[Display system]
The display system 10 shown in FIG. 1 is mounted on a vehicle 1 (see FIG. 2). The vehicle 1 is an example of a moving body in the present invention, and is an automobile having a drive source and wheels including drive wheels driven by the power of the drive source and steerable wheels. In this embodiment, the vehicle 1 is a four-wheeled automobile having a pair of left and right front wheels and rear wheels. The drive source of the vehicle 1 may be an electric motor, an internal combustion engine such as a gasoline engine or a diesel engine, or a combination of an electric motor and an internal combustion engine. In addition, the drive source of the vehicle 1 may drive a pair of left and right front wheels, a pair of left and right rear wheels, or four wheels including a pair of left and right front wheels and rear wheels. Either one of the front wheels and the rear wheels may be a steerable wheel, or both of them may be steerable wheels.

The display system 10 includes a front camera 11, a side camera 12, a rear camera 13, various sensors 14, a navigation device 15, a display device 16, a display switching operation button 17, and a control device 18. The components of the display system 10 are connected to each other via a wired or wireless communication network so that they can communicate with each other.

As shown in FIG. 2, the front camera 11 is a camera that captures an image of the area FF in front of the vehicle 1, and is provided, for example, at the front end of the vehicle 1. Note that the front camera 11 only needs to be able to capture an image of the area FF in front of the vehicle 1, and its location is not limited to the front end of the vehicle 1, and it may be, for example, the back of a rearview mirror, etc.

As shown in FIG. 2, the side camera 12 is a camera that photographs the lateral areas (left and right) of the vehicle 1, and is composed of a right side camera 12R that photographs the right side area SR and a left side camera 12L that photographs the left side area SL. For example, the right side camera 12R is provided on the right door mirror 11R, and the left side camera 12L is provided on the left door mirror 11L. Note that the right side camera 12R only needs to be able to photograph the right side area SR, and its location is not limited to the right door mirror 11R, and it may be, for example, near the right front fender. Similarly, the left side camera 12L only needs to be able to photograph the left side area SL, and its location is not limited to the left door mirror 11L, and it may be, for example, near the left front fender.

As shown in FIG. 2, the rear camera 13 is a camera that captures an image of the rear area RR of the vehicle 1, and is provided, for example, at the rear end of the vehicle 1. Note that the rear camera 13 only needs to be able to capture an image of the rear area RR of the vehicle 1, and its location is not limited to the rear end of the vehicle 1 and may be, for example, at the upper position of the rear window.

The various sensors 14 are an example of an acquisition unit that acquires information regarding the moving state of the vehicle 1. For example, the various sensors 14 acquire information indicating the traveling speed of the vehicle 1 (hereinafter also referred to as "vehicle speed") as information regarding the moving state of the vehicle 1. The various sensors 14 may also acquire information indicating the steering angle of the vehicle 1 or information indicating the accelerator position (hereinafter also referred to as "AP") of the vehicle 1 as information regarding the moving state of the vehicle 1. In other words, the various sensors 14 may include a vehicle speed sensor that detects the vehicle speed, an AP sensor that detects the AP of the vehicle 1, a steering angle sensor that detects the steering angle of the vehicle 1, etc.

The navigation device 15 includes a storage device (e.g., a flash memory) that stores map data and the like, a GNSS (Global Navigation Satellite System) receiver that can identify the current position of the vehicle 1 (hereinafter also referred to as the "vehicle position") based on signals received from positioning satellites, and operation buttons (including a touch panel) that accept operations from a user (e.g., the driver of the vehicle 1, hereinafter also simply referred to as the "driver"). The navigation device 15, for example, determines a route (hereinafter the "guided route") from the vehicle position to a destination set by the user by referring to map data and the like, and guides the driver along the determined guided route via a display device 16, which will be described later, and the like.

The display device 16 notifies the driver of information by displaying an image. The display device 16 is disposed, for example, in front of the driver's seat and constitutes an instrument panel. The display device 16 can display a front view screen G1 as exemplified in FIG. 3, a navigation screen G2 as exemplified in FIG. 4, and a side view screen G3 as exemplified in FIG. 5.

The front view screen G1 is an example of a first screen in the present invention, and is a screen generated based on an image captured by the front camera 11. As shown in FIG. 3, the front view screen G1 displays, for example, a forward image V1, which is an image showing the forward area FF of the vehicle 1, and an overhead image V2, which is a bird's-eye view of the vehicle 1 from directly above. The overhead image V2 can be generated by combining images captured by the front camera 11, the side camera 12, and the rear camera 13.

The navigation screen G2 is an example of a second screen in the present invention, and is a screen generated by the navigation device 15. As shown in FIG. 4, the navigation screen G2 displays, for example, a map image M showing a map of the vicinity of the vehicle's position or a point specified by the user. In addition, the guide line RL showing the above-mentioned guide route and the vehicle's position icon I showing the vehicle's position may be displayed on the map image M.

The side view screen G3 is a screen generated based on an image captured by the side camera 12. As shown in FIG. 5, the side view screen G3 displays, for example, a right side image V3 which is an image showing a part of the right side area SR of the vehicle 1 (e.g., near the right front wheel), a left side image V4 which is an image showing a part of the left side area SL (e.g., near the left front wheel), and an overhead image V2. The side view screen G3 is used, for example, when the vehicle 1 turns right or left, when pulling over, or when parking.

The display switching operation button 17 constitutes an operation unit for switching the screen displayed on the display device 16 to another screen. The display switching operation button 17 is provided in a position where the driver can easily operate it, such as near the steering wheel. This improves the operability of the display switching operation button 17 by the driver.

The control device 18 controls the display device 16 to display various screens on the display device 16. The control device 18 includes an acquisition unit 181 and a display control unit 182.

The acquisition unit 181 is a functional unit that acquires information related to the moving state of the vehicle 1. The acquisition unit 181 acquires, for example, information indicating the vehicle speed as information related to the moving state of the vehicle 1. The information indicating the vehicle speed can be acquired based on the detection results of a vehicle speed sensor included in the various sensors 14.

The display control unit 182 is a functional unit that controls the display device 16. The display control unit 182 causes the display device 16 to display one of a number of types of screens, including, for example, a front view screen G1, a navigation screen G2, and a side view screen G3. When the display switching operation button 17 is operated, the display control unit 182 also switches the screen displayed on the display device 16 to another screen.

In this embodiment, when the vehicle speed is equal to or greater than a predetermined threshold value of 25 km/h (predetermined state), the display control unit 182 switches the screen to be displayed on the display device 16 from among the first screen group, which includes a front view screen G1 and a navigation screen G2, but does not include a side view screen G3, as shown in FIG. 6, each time the display switching operation button 17 is operated, when the vehicle speed is less than 25 km/h, the display control unit 182 switches the screen to be displayed on the display device 16 from among the second screen group, which includes a front view screen G1, a navigation screen G2, and a side view screen G3, as shown in FIG. 7, each time the display switching operation button 17 is operated.

The control device 18 is realized by a computer (e.g., an ECU: Electronic Control Unit) equipped with a CPU (Central Processing Unit) that performs various calculations, a storage device that stores various information, and an input/output device that controls the input and output of data between the inside and outside of the control device 18. That is, the functions of the acquisition unit 181 and the display control unit 182 described above can be realized, for example, by the CPU executing a predetermined program (display switching program) that is pre-stored in the storage device. In addition, some or all of the functions of the control device 18 may be realized by hardware such as an LSI (Large Scale Integration), an ASIC (Application Specific Integrated Circuit), an FPGA (Field-Programmable Gate Array), or a GPU (Graphics Processing Unit). Furthermore, some or all of the functions of the control device 18 may be realized by collaboration between software and hardware.

[Display switching process executed by the control device]
Next, an example of a display switching process (display switching method) executed by the control device 18 will be described with reference to Fig. 8. Note that the control device 18 executes the display switching process shown in Fig. 8, for example, when the navigation screen G2 is displayed on the display device 16.

As shown in FIG. 8, the control device 18 first determines whether the display switching operation button 17 has been pressed (step S1). If the control device 18 determines that the display switching operation button 17 has been pressed (step S1: Yes), the control device 18 causes the display device 16 to display the front view screen G1 (step S2).

Then, the control device 18 determines whether the display switching operation button 17 has been pressed (step S3). If the control device 18 determines that the display switching operation button 17 has been pressed (step S3: Yes), it acquires the vehicle speed (step S4) and then executes the process of step S5.

In step S5, the control device 18 determines whether the vehicle speed is 25 km/h or more. If the control device 18 determines that the vehicle speed is 25 km/h or more (step S5: Yes), the control device 18 causes the display device 16 to display the navigation screen G2 (step S6). That is, the control device 18 switches the display screen of the display device 16 from the front view screen G1 to the navigation screen G2.

In this way, when the vehicle speed is 25 km/h or higher, it is assumed that the vehicle 1 is unlikely to turn right or left or be parked in the near future. Therefore, by not displaying the side view screen G3, the control device 18 can reduce the number of operations required by the user to display the navigation screen G2 that is likely to be desired by the user, thereby improving user convenience.

On the other hand, if the control device 18 determines that the vehicle speed is less than 25 km/h (step S5: No), it causes the display device 16 to display the side view screen G3 (step S7). That is, the control device 18 switches the display screen of the display device 16 from the front view screen G1 to the side view screen G3.

In this way, when the vehicle speed is below 25 km/h (i.e., low speed), it is assumed that there is a possibility that the vehicle 1 will turn right or left or be parked in the near future, and therefore the control device 18 can support the safe movement of the vehicle 1 by displaying the side view screen G3. Specifically, as described above, the side view screen G3 includes the right side image V3, the left side image V4, and the overhead image V2, and therefore it is possible to guide the driver of the situation around the vehicle 1, thereby supporting the safe movement of the vehicle 1.

Then, the control device 18 determines whether the display switching operation button 17 has been pressed (step S8). If the control device 18 determines that the display switching operation button 17 has been pressed (step S8: Yes), the control device 18 causes the display device 16 to display the navigation screen G2 (step S9). That is, the control device 18 switches the display screen of the display device 16 from the side view screen G3 to the navigation screen G2, which was displayed before the front view screen G1 was displayed.

In this way, even if the side view screen G3 is displayed on the display device 16 because the vehicle speed is less than 25 km/h, when the display switching operation button 17 is pressed, the display screen of the display device 16 can be switched to the navigation screen G2, thereby quickly returning to the navigation screen G2 that was displayed before the front view screen G1 was displayed, thereby improving user convenience.

As described above, the control device 18 enables the user to switch to an appropriate screen (i.e., the screen desired by the user) according to the vehicle speed (moving state) through a simple operation (pressing operation) using the display switching operation button 17, which is a single operation unit, thereby improving user convenience.

Although the embodiment of the present invention has been described above with reference to the attached drawings, it goes without saying that the present invention is not limited to such an embodiment. It is clear that a person skilled in the art can come up with various modified or revised examples within the scope of the claims, and it is understood that these also naturally fall within the technical scope of the present invention. Furthermore, the components in the above embodiment may be combined in any manner as long as it does not deviate from the spirit of the invention.

For example, in the above-described embodiment, the way in which the display screen of the display device 16 is switched (whether or not the side view screen G3 is displayed) is changed depending on whether or not the vehicle speed is equal to or greater than a predetermined threshold value of 25 km/h, but this is not limited to the above.

For example, instead of the vehicle speed, the display screen of the display device 16 may be switched differently based on the AP of the vehicle 1. Specifically, when the AP of the vehicle 1 is equal to or greater than a predetermined threshold (in other words, when the accelerator pedal is pressed hard), it is assumed that the vehicle 1 is unlikely to turn right or left or be parked in the near future, and so the control device 18 may not display the side view screen G3. On the other hand, when the AP of the vehicle 1 is less than the threshold, it is assumed that the vehicle 1 is likely to turn right or left or be parked in the near future, and so the control device 18 may display the side view screen G3.

In addition, instead of the vehicle speed, the display screen of the display device 16 may be switched differently based on the steering angle of the vehicle 1. Specifically, when the steering angle of the vehicle 1 is less than a predetermined threshold (in other words, when the steering wheel is not turned by a predetermined amount or more), it is assumed that the vehicle 1 is unlikely to turn right or left or be parked in the near future, and the control device 18 may not display the side view screen G3. On the other hand, when the steering angle of the vehicle 1 is equal to or greater than the threshold, it is assumed that the vehicle 1 is likely to turn right or left or be parked in the near future, and the control device 18 may display the side view screen G3.

In the above-described embodiment, an example in which the navigation screen G2 is displayed has been described as an example of the second screen in the present invention, but this is not limiting. For example, instead of the navigation screen G2, an audio-visual screen (content playback screen) for playing predetermined content such as music data may be displayed on the display device 16 as the second screen. With this configuration, in a situation in which it is considered unlikely that the vehicle 1 will turn right or left or be parked in the near future, the audio-visual screen can be displayed quickly, thereby improving user convenience.

In the above embodiment, the moving body in the present invention is described as a four-wheeled automobile, namely, vehicle 1, but is not limited to this. The moving body in the present invention may be a two-wheeled automobile (a so-called motorcycle), a Segway, a ship, an aircraft, or the like.

The display switching method described in the above embodiment can be realized by executing a prepared program (display switching program) on a computer. The display switching program is stored in a computer-readable storage medium and is executed by reading it from the storage medium. The display switching program may be provided in a form stored in a non-volatile (non-transient) storage medium such as a flash memory, or may be provided via a network such as the Internet. The computer that executes the display switching program may be included in a control device mounted on a mobile object, or may be included in a terminal device such as a smartphone, tablet terminal, or personal computer that can communicate with the mobile object, or may be included in a server device that can communicate with the mobile object.
