Description

The present invention relates to an information processing system, a server device, a control method for a server device, a program, and a storage medium.

Patent Document 1 discloses an alarm output device that includes a sensor unit that detects a first obstacle behind the vehicle, and an alarm output unit that outputs an alarm to notify the occupant of the presence of the first obstacle based on information from the sensor unit when the shift position is in the reverse range.

JP 2018-106429 A

However, Patent Document 1 does not control the content of the notification depending on the type of vehicle. For example, because four-wheeled vehicles can move backward, it is necessary to issue a notification to warn the driver if there is a person (especially a child) behind the vehicle. On the other hand, because two-wheeled vehicles do not move backward (do not back up), there is no need to issue a notification even if there is a person behind the vehicle.

The present invention was made in consideration of the above-mentioned problems, and aims to provide technology for notifying appropriate information depending on the type of vehicle.

Embodiments of the present invention will be described below with reference to the accompanying drawings. Note that each figure is merely a schematic diagram for explaining the embodiments, and for example, the dimensions of each element in the figure do not necessarily reflect actual dimensions. Furthermore, identical elements in the figures are assigned the same reference numbers, and explanations of overlapping content will be omitted in this specification.

<Overview>
In this embodiment, an application for a child monitoring service will be described as an example. Each child carries a mobile terminal device associated with the child when going to and from school. When a child carrying a mobile information terminal is present near the vehicle while the vehicle is stopped or parked, information indicating the presence of the child is notified to alert the driver of the vehicle.

When issuing this warning, the system controls the system so that appropriate information is provided depending on the type of vehicle. For example, if the vehicle is a four-wheeled vehicle, the four-wheeled vehicle can travel in both forward and backward directions. Therefore, information indicating the presence of a child is notified to the driver both when the child is in front of the vehicle and when the child is at the rear of the vehicle. On the other hand, if the vehicle is a two-wheeled vehicle, the two-wheeled vehicle can only travel in the forward direction and, as a general rule, does not move backward. Therefore, there is little need to issue a warning when there is a child at the rear of the vehicle. Therefore, the system controls the system so that information indicating the presence of a child is not provided to the driver when there is a child in front of the vehicle. In this way, the system takes into account the type of vehicle and does not issue a warning when it is not necessary, thereby preventing excessive information from being issued.

<System Configuration>
1 is a diagram illustrating the configuration of an information processing system according to one embodiment. The information processing system includes a server device 10, one or more first vehicles 21, one or more second vehicles 22, and one or more mobile terminal devices 30, which are configured to be able to communicate with each other via a network 40. The network 40 is, for example, the Internet and/or a local area network (LAN). The one or more first vehicles 21 are, for example, four-wheeled vehicles. The one or more second vehicles 22 are, for example, two-wheeled vehicles. The one or more mobile terminal devices 30 are, for example, communication devices such as smartphones carried by one or more children.

<Device configuration>
Next, with reference to FIGS. 2 and 3, an example of the configuration of a vehicle and devices that constitute an information processing system according to an embodiment will be described.

Figure 2(a) is a diagram showing an example configuration of a server device in an information processing system according to one embodiment. The server device 10 includes a CPU 101, a storage device 102, and a communication unit 103. The CPU 101 controls the operation of the server device 10 by reading and executing programs stored in the storage device 102. The storage device 102 stores various types of information. The storage device 102 stores programs for the CPU 101 to read and execute, and can also store information acquired from one or more first vehicles 21, one or more second vehicles 22, and mobile terminal devices 30 via the communication unit 103, as well as processing results of the acquired information. The communication unit 103 transmits and receives various types of information via wired or wireless connections.

Figure 2(b) is a diagram showing an example configuration of a mobile terminal device in an information processing system according to one embodiment. The mobile terminal device 30 is a mobile information terminal such as a smartphone, and is carried by a child who is registered for the monitoring service provided by the information processing system according to this embodiment. The mobile terminal device 30 includes a CPU 301, a storage device 302, a communication unit 303, a display unit 304, an operation input unit 305, a GPS sensor 306, and a gyro sensor 307. The CPU 301 controls the operation of the mobile terminal device 30 by reading and executing programs stored in the storage device 302.

The storage device 302 stores programs that the CPU 301 reads and executes, as well as various information input to the mobile terminal device 30 via the operation input unit 305. The communication unit 303 communicates with the server device 10 via the network 40, and can send and receive various information via wired or wireless connections.

The display unit 304 is a liquid crystal display or the like, and can display various types of information. The operation input unit 305 is a physical button, a touch panel button, or the like. The child who owns the mobile terminal device 30 or their guardian can operate the operation input unit 305 to input various types of information. If the display unit 304 is a touch panel, the display unit 304 may also function as the operation input unit 305.

The GPS sensor 306 detects the current location of the mobile terminal device 30 on Earth and the current time by receiving radio waves generated by artificial satellites.

Figure 3(a) is a diagram showing an example configuration of a first vehicle according to one embodiment. The first vehicle 21 is, for example, a four-wheeled vehicle. The first vehicle 21 includes an ECU (electronic control unit) 211, a storage device 212, a communication unit 213, an on-board navigation device 214, an external camera 215, and a speaker 216.

The ECU 211 includes a CPU, memory, and a communication interface. The CPU performs predetermined processing based on information (data or electrical signals) received via the communication interface, and stores the processing results in memory or storage device 212, or outputs them to other elements via the communication interface. The ECU 211 controls the drive mechanism based on the amount of operation of the acceleration operator (accelerator pedal) by the driver. The ECU 211 also controls the braking mechanism based on the amount of operation of the braking operator (brake pedal) by the driver. The braking mechanism is, for example, a disc brake provided on each wheel of the first vehicle 21. The ECU 211 also controls the steering mechanism based on the amount of operation of the steering operator (steering wheel) by the driver. The steering mechanism includes power steering.

The storage device 212 stores various information, such as image data captured by the external camera 215. It also stores information such as departure and destination points entered via the in-vehicle navigation device 214. The communication unit 213 communicates with the server device 10 via the network 40, and can send and receive various information via wired or wireless connections.

The in-vehicle navigation device 214 comprises a display unit 2141 and an operation input unit 2142. The display unit 2141 is an LCD display or the like, and displays various navigation information such as route information from the departure point (or current location) to the destination (or intermediate location), and displays various information based on information received from the server device 10. The operation input unit 2142 is a physical button, a rotary mechanism, or the like, and the driver (user) can operate the operation input unit 2142 to input various navigation information such as the departure point and destination. Note that if the display unit 2141 is a touch panel, the display unit 2141 may also function as the operation input unit 2142.

The exterior camera 215 captures images of the surroundings of the first vehicle 21. For example, the camera may capture images of the front, rear, and/or sides of the first vehicle 21. An around-view of the first vehicle 21 may also be captured. The speaker 216 outputs audio information to the occupants of the first vehicle 21. The GPS sensor 217 receives radio waves generated by artificial satellites to detect the current position and current time of the first vehicle 21 on Earth. The orientation sensor 218 detects the current orientation (direction) of the first vehicle 21.

Figure 3(b) is a diagram showing an example configuration of a second vehicle according to one embodiment. The second vehicle 22 is, for example, a motorcycle. The first vehicle 22 includes an ECU (electronic control unit) 221, a storage device 222, a communication unit 223, an on-board navigation device 224, an external camera 225, and a speaker 226.

The ECU 221 includes a CPU, memory, and a communication interface. The CPU performs predetermined processing based on information (data or electrical signals) received via the communication interface, and stores the processing results in memory or storage device 222, or outputs them to other elements via the communication interface. The ECU 221 controls the drive mechanism based on the amount of operation of an acceleration operator (accelerator) by the driver. The ECU 221 also controls the braking mechanism based on the amount of operation of a braking operator (e.g., brake) by the driver. The braking mechanism is, for example, a disc brake provided on each wheel of the second vehicle 22.

The storage device 222 stores various information, such as image data captured by the external camera 225. It also stores information such as departure and destination points entered via the in-vehicle navigation device 224. The communication unit 223 communicates with the server device 10 via the network 40, and can send and receive various information via wired or wireless connections.

The in-vehicle navigation device 224 comprises a display unit 2241 and an operation input unit 2242. The display unit 2241 is an LCD display or the like, and displays various navigation information such as route information from the departure point (or current location) to the destination (or intermediate location), and displays various information based on information received from the server device 10. The operation input unit 2242 is a physical button, a rotary mechanism, or the like, and the driver (user) can operate the operation input unit 2242 to input various navigation information such as the departure point and destination. Note that if the display unit 2241 is a touch panel, the display unit 2241 may also function as the operation input unit 2242.

The exterior camera 225 captures images of the surroundings of the second vehicle 22, such as the area in front of and/or behind the second vehicle 22. The speaker 226 outputs audio information to the occupants of the second vehicle 22. The GPS sensor 227 receives radio waves generated by artificial satellites to detect the current position and time of the second vehicle 22 on Earth. The orientation sensor 228 detects the current orientation (direction) of the second vehicle 22.

<Processing>
Next, an example of a processing sequence executed in the information processing system according to an embodiment will be described with reference to Fig. 4. It is assumed that a child or his/her guardian has registered in advance with an application that provides a child monitoring service using the child's mobile terminal device 30.

In F401, the mobile terminal device 30 carried by the child acquires location information of the mobile terminal device 30, for example, via the GPS sensor 306. This process is performed continuously at predetermined intervals. In F402, the first vehicle 21 acquires location information of the first vehicle 21, for example, via the GPS sensor 217, and acquires orientation information of the first vehicle 21 via the orientation sensor 218. This process is performed continuously at predetermined intervals. In F403, the second vehicle 22 acquires location information of the second vehicle 22, for example, via the GPS sensor 227, and acquires orientation information of the second vehicle 22 via the orientation sensor 228. This process is performed continuously at predetermined intervals.

In F404, the mobile terminal device 30 transmits the position information of the mobile terminal device 30 acquired in F401 to the server device 10. This process is performed continuously at predetermined intervals. In F405, the first vehicle 21 transmits the position and orientation information of the first vehicle 21 acquired in F402 to the server device 10. This process is performed continuously at predetermined intervals. In F406, the first vehicle 22 transmits the position and orientation information of the second vehicle 22 acquired in F403 to the server device 10. This process is performed continuously at predetermined intervals.

In this way, the server device 10 periodically receives location information of the mobile terminal devices 30 of registered children from the mobile terminal devices 30. The server device 10 also periodically receives information indicating the location and orientation of each first vehicle from each first vehicle, and periodically receives information indicating the location and orientation of each second vehicle from each second vehicle.

In F407, the server device 10 determines whether the situation warrants notification of the presence of a child based on the information received in F404 to F406.

In F408, the server device 10 transmits first information to the first vehicle 21 based on the location information of the mobile terminal device 30 and the location and orientation information of the first vehicle 21. Here, the first information is information about the mobile terminal device 30 that is located within a predetermined range from the first vehicle 21 and in a direction that the first vehicle 21 can travel (e.g., forward and/or backward). If a mobile terminal device 30 is located within a predetermined range from the first vehicle 21 and in a direction that the first vehicle 21 can travel (e.g., forward and/or backward), it can be determined that a situation requires the presence of a child to be reported. At this time, information including the positional relationship between the first vehicle 21 and the child (mobile terminal device 30), such as information indicating the presence of a child in front of the first vehicle 21, information indicating the presence of a child behind the first vehicle 21, or information indicating the presence of a child both in front and behind the first vehicle 21, is transmitted.

Here, Figure 6 is an explanatory diagram illustrating the positional relationship between the first vehicle 21 and a child carrying a mobile terminal device 30 according to one embodiment, and the need for notification. In this embodiment, the first vehicle 21 is a four-wheeled vehicle that can travel in two directions: forward and backward. Therefore, as shown in Figure 6, within a predetermined range 601 of the first vehicle 21 (for example, within a distance of 50 m from the vehicle), it is necessary to notify the presence of the vehicle in both cases: when a child carrying a mobile terminal device 30a is in front of the vehicle, and when a child carrying a mobile terminal device 30b is behind the vehicle. Note that if there is no need for notification, the server device 10 does not transmit the first information to the first vehicle 21.

In F409, the server device 10 transmits second information to the second vehicle 22 based on the location information of the mobile terminal device 30 and the location and orientation information of the second vehicle 22. Here, the second information is information about the mobile terminal device 30 that is located within a predetermined range from the second vehicle 22 and in the direction in which the second vehicle 22 can travel (e.g., forward). At this time, information including the positional relationship between the second vehicle 22 and the child (mobile terminal device 30), such as information indicating that a child is located in front of the second vehicle 22, is transmitted.

Here, Figure 7 is an explanatory diagram illustrating the positional relationship between the second vehicle 22 and a child carrying a mobile terminal device 30 according to one embodiment, and the need for notification. In this embodiment, the second vehicle 21 is a two-wheeled vehicle with one possible direction of travel: forward. Therefore, as shown in Figure 7, if a child carrying a mobile terminal device 30a is present in front of the second vehicle 22 within a predetermined range 701 from the vehicle (for example, within a distance of 50 m from the vehicle), a notification is required. On the other hand, if a child carrying a mobile terminal device 30b is present behind the vehicle, the second vehicle 22 is unlikely to move backward (reverse), and therefore there is little need to notify the child's presence, and therefore no notification is performed. Note that if there is no need for notification, the server device 10 does not transmit the second information to the second vehicle 22.

In F410, the first vehicle 21 issues warning information indicating the need to be careful of the presence of a child based on the first information received from the server device 10. At this time, the notification includes the relative positions of the first vehicle 21 and the child (mobile terminal device 30), such as "There is a child ahead. Be careful," "There is a child behind. Be careful," or "There are children ahead and behind. Be careful." Figure 8(a) shows an example of a display on the display unit 2141 of the first vehicle 21 according to one embodiment. In the illustrated example, a text message is displayed warning the driver that there are children ahead and behind the first vehicle 21 and that caution is required. Alternatively, or in addition to this, the first vehicle 21 may issue an audio notification via the speaker 216. Furthermore, as in the illustrated example, an icon indicating the relative positions of the vehicle and the child may be displayed to visually alert the driver. In the illustrated example, because children are present both ahead and behind the vehicle, the icons at both the front and rear of the vehicle are lit (or flashing). Instead of sending a text or voice message, notifications may be sent by flashing an icon and sounding an alarm.

In F411, the second vehicle 22 issues warning information indicating the need to be careful of the presence of a child based on the second information received from the server device 10. At this time, the notification includes the relative positions of the second vehicle 22 and the child (mobile terminal device 30), such as "There is a child ahead. Please be careful." Figure 8(b) shows an example of a display on the display unit 2241 of the second vehicle 22 according to one embodiment. In the illustrated example, a text message is displayed warning the driver that a child is ahead of the second vehicle 22 and caution is required. Alternatively, or in addition to this, the second vehicle 22 may issue an audio notification via the speaker 226. Furthermore, as in the illustrated example, an icon indicating the relative positions of the vehicle and the child may be displayed to provide a visually easy-to-recognize warning. In the illustrated example, the icon at the front of the vehicle is lit (or flashing) because a child is ahead of the vehicle. Notification may also be made by flashing the icon and sounding an alarm, without a text or audio message. In the case of the second vehicle 22, the only direction of travel is forward, so notifications are only issued when there are children in the front. In this way, notifications are not issued when there are children in the rear, preventing unnecessary (excessive) information from being provided to occupants.

This completes the processing sequence shown in Figure 4. When implemented, the processing sequence shown in Figure 4 will be repeated. Note that the order of each process is an example, and the order may be changed. Specifically, the processing order of F401 to F406 is not limited to the example shown. Furthermore, the processing order of F408 to F411 is not limited to the example shown.

<Server Device Processing>
Next, the procedure of the process performed by the server device 10 according to an embodiment will be described with reference to the flowchart of FIG.

At S501, the server device 10 acquires location information for each mobile terminal device 30 carried by each child. That is, it collects location information for one or more mobile terminal devices 30 registered with the child monitoring service. At S502, the server device 10 acquires location and orientation information for each first vehicle 21 from one or more first vehicles 21. At S503, the server device 10 acquires location and orientation information for each second vehicle 22 from one or more second vehicles 22.

In S504, the server device 10 determines whether a mobile terminal device 30 is present within a predetermined range from the first vehicle 21 and in the possible direction of travel of the first vehicle 21. This process is performed for each of one or more first vehicles 21. If this step is Yes, proceed to S505. On the other hand, if this step is No, proceed to S506.

At S505, the server device 10 transmits first information to the first vehicle 21 based on the location information of the mobile terminal device 30 and the location and orientation information of the first vehicle 21. Here, the first information is information about the mobile terminal device 30 that is located within a predetermined range of the first vehicle 21 and in a direction in which the first vehicle 21 can travel (e.g., forward and/or backward). At this time, information including the positional relationship between the first vehicle 21 and the child (mobile terminal device 30) is transmitted, such as information indicating the presence of a child in front of the first vehicle 21, information indicating the presence of a child behind the first vehicle 21, or information indicating the presence of a child both in front and backward. This makes it possible for the first vehicle 21 to issue warning information that also includes the positional relationship between the vehicle and the child.

In S506, the server device 10 determines whether a mobile terminal device 30 is present within a predetermined range from the second vehicle 22 and in the direction in which the second vehicle 22 can travel. This process is performed for each of one or more second vehicles 22. If this step is Yes, proceed to S507. On the other hand, if this step is No, the process ends.

At S507, the server device 10 transmits second information to the second vehicle 22 based on the location information of the mobile terminal device 30 and the location and orientation information of the second vehicle 22. Here, the second information is information about the mobile terminal device 30 that is located within a predetermined range from the second vehicle 22 and in the direction in which the second vehicle 22 can travel (e.g., ahead). At this time, information including the positional relationship between the second vehicle 22 and the child (mobile terminal device 30), such as information indicating that a child is present in front of the second vehicle 22, is transmitted. This makes it possible for the second vehicle 22 to issue warning information that also includes the positional relationship between the vehicle and the child.

As described above, in this embodiment, the vehicle is controlled to provide appropriate information depending on the type of vehicle. For example, if the vehicle is a four-wheeled vehicle, the four-wheeled vehicle can travel in both forward and backward directions. Therefore, information indicating the presence of a child is notified to the driver both when the child is in front of the vehicle and when the child is at the rear of the vehicle. On the other hand, if the vehicle is a two-wheeled vehicle, the two-wheeled vehicle can only travel in the forward direction and, as a general rule, does not move backward. Therefore, there is little need to provide a notification when a child is at the rear of the vehicle. Therefore, the system is controlled to provide information indicating the presence of a child to the driver when a child is in front of the vehicle. In this way, the type of vehicle is taken into consideration and a warning is not issued when it is not necessary, thereby preventing excessive notification of information.

This makes it possible to improve the safety of children registered with the monitoring service while preventing excessive notification of information to vehicle occupants. Furthermore, since information is not sent from the server device to the second vehicle when notification is not necessary, data communication volume can be reduced.

Note that the processing order in Figure 5 is an example and various modifications are possible. For example, the processing of S501 to S503 may be performed in a different order. The determination processing of S504 and S506 may also be performed in the reverse order. Furthermore, the transmission processing of S505 and S507 may be performed after the determination processing of S504 and S506.

[Variations]
In the above embodiment, an example was described in which the criteria for whether or not to notify the driver of the presence of a child around the vehicle were changed depending on the type of vehicle (possible traveling direction). Furthermore, an example was described in which, if the vehicle is a four-wheeled vehicle, a notification is given when a child is present in front of and/or behind the vehicle, and if the vehicle is a two-wheeled vehicle, a notification is given when a child is present in front of the vehicle. In this case, the distance between the vehicle and the mobile terminal device 30 carried by the child may also be notified. For example, the notification may be configured to include information such as, "There is a child 30 meters ahead of the vehicle. Please be careful."

The movement history of the mobile terminal device 30 carried by the child may also be monitored, and the server device 10 may determine information indicating whether the child is approaching or moving away from the vehicle, and transmit such information to the first vehicle 21 and the second vehicle 22. In this case, when a child is approaching the vehicle, the first vehicle 21 and the second vehicle 22 may issue a warning including information indicating the child's movement status, such as "A child is approaching from the front. Please be careful." Furthermore, when a child is moving away from the vehicle, when a child is present within a specified range of the vehicle and an alert is issued regarding the child's presence, information such as "There is a child behind the vehicle. He is moving away from the vehicle, so please be careful." This makes it possible to alert the vehicle occupants with more specific information, making it easier for them to understand the situation around them.

The first vehicle 21 may also control the notification taking into consideration information obtained by analyzing images captured by the exterior camera 215. For example, when the first vehicle 21 receives information from the server device 10 indicating that a child is present in front of the first vehicle 21, the first vehicle 21 may analyze the images captured by the exterior camera 215. If a person (child) is detected in the images, the first vehicle 21 may display an image (or video) of the person on the display unit 2141 along with warning information. Similarly, the second vehicle 22 may also control the notification taking into consideration information obtained by analyzing images captured by the exterior camera 225. For example, when the first vehicle 21 receives information from the server device 10 indicating that a child is present in front of the second vehicle 22, the first vehicle 21 may analyze the images captured by the exterior camera 225. If a person (child) is detected in the images, the second vehicle 22 may display an image (or video) of the person on the display unit 2241 along with warning information. This enables the actual surrounding situation to be grasped early.

Furthermore, in the case of four-wheeled vehicles, control may be performed taking into account the gear range. For example, when the gear is in reverse, the system may be configured to only alert the driver of the presence of a child located behind the vehicle. In other words, when the gear is in reverse, the system may be configured not to alert the driver of a child located in front of the vehicle.

(Other embodiments)
Furthermore, a program that realizes one or more functions described in each embodiment can be supplied to a system or device via a network or a storage medium, and one or more processors in a computer of the system or device can read and execute the program. The present invention can also be realized in such an embodiment.

The invention is not limited to the above-described embodiments, and various modifications and variations are possible within the scope of the invention.

the notification means of the first vehicle, when receiving the first information from the server device, notifies information indicating that the mobile terminal device is present in a travelable direction (for example, forward and backward) of the first vehicle;
When the notification means of the second vehicle receives the second information from the server device, it notifies information indicating that the mobile terminal device is present in a direction in which the second vehicle can travel (e.g., ahead).

This allows different information to be displayed depending on the vehicle's possible direction of travel, making it possible to display appropriate information.

3. In the information processing system according to the third aspect,
the first transmitting means of the server device transmits, as the first information, information about the mobile terminal device that is present within a predetermined range from the first vehicle and in a travelable direction of the first vehicle;
The second transmitting means of the server device transmits, as the second information, information relating to the mobile terminal device that is present within a predetermined range from the second vehicle and in a direction in which the second vehicle can travel.

This allows information about children who are near the vehicle and in the direction the vehicle can move, reducing the amount of unnecessary information being reported, such as information about children who are in the direction the vehicle cannot move.

4. In the information processing system according to the fourth aspect,
the first information is information about the mobile terminal device that is located within a predetermined range from the first vehicle and in a travelable direction of the first vehicle,
the second information is information about the mobile terminal device that is located within a predetermined range from the second vehicle and in a travelable direction of the second vehicle,
The number of directions in which the second vehicle can travel is smaller than the number of directions in which the first vehicle can travel.

This reduces the frequency of notifications in the second vehicle, making it possible to prevent excessive notification of information.

5. In an information processing system according to a fifth aspect,
the number of directions in which the second vehicle can travel is one, i.e., forward of the vehicle;
The number of directions in which the first vehicle can travel is two, that is, forward and backward.

As a result, the second vehicle will only issue a notification if there is a child carrying a mobile terminal device in front of the vehicle, reducing the frequency of notifications in the second vehicle and preventing excessive notifications of information.

6. In an information processing system according to a sixth aspect,
The first vehicle is a four-wheeled vehicle, and the second vehicle is a two-wheeled vehicle.

This makes it possible to provide appropriate information depending on the type of vehicle, i.e., distinguishing between four-wheeled vehicles and two-wheeled vehicles.

7. In an information processing system according to a seventh aspect,
the first transmitting means of the server device transmits the first information to the first vehicle based on the position information of the mobile terminal device and the position and orientation information of the first vehicle when the speed of the first vehicle is equal to or less than a threshold;
When the speed of the second vehicle is below a threshold, the second transmitting means of the server device transmits the second information to the second vehicle based on the position information of the mobile terminal device and the position and orientation information of the second vehicle.

As such, when traveling at a certain speed, it is unlikely that the vehicle's direction of travel will change immediately. In such a situation, there is less need to change whether or not to notify depending on the vehicle's possible traveling direction. For example, it is unlikely that the vehicle will suddenly start reversing when traveling forward at a certain speed. Therefore, there is little need to distinguish between vehicle types. More specifically, there is little need to distinguish between four-wheeled vehicles and two-wheeled vehicles. Therefore, it is possible to provide appropriate information according to the type of vehicle in necessary situations, such as when the vehicle is stopped, parked, or traveling at low speeds.
