Description

  The present invention relates to a vehicle position guidance system, and more particularly to a vehicle position guidance system for guiding a vehicle parking position to a user of the vehicle.

  In a parking lot attached to a leisure land, a shopping mall, etc., a large number of vehicles are accommodated in a vast area, so that the vehicle user who wants to return to the parked vehicle may hesitate without remembering the parking position. . For such a case, a vehicle position guidance system that guides the parking position of the host vehicle to the user has already been developed. As such a vehicle position guidance system, for example, a vehicle position guidance system including a vehicle-mounted device that detects the position and altitude of the vehicle and a mobile communication terminal that displays a three-dimensional map is known (Patent Document 1). .

  In addition, in large-scale parking lots such as those mentioned above, not only luxury cars but also vehicles equipped with expensive electrical equipment are parked, so depending on the scale of the security equipment and security posture of the parking lot, It is assumed that you will encounter vandalism aiming at the vehicle. In recent years, an increasing number of vehicles are equipped with a security system that detects a suspicious person approaching the vehicle. For example, a vehicle equipped with a security device equipped with a monitoring sensor is known (Patent Document 2). The security device described in Patent Document 2 notifies the user of the act of the suspicious person when the suspicious person approaches the vehicle or when the vehicle is physically harmed, and responds to the user's request. Thus, an image around the vehicle can be transmitted to the user's portable communication terminal.

  However, in a security device such as that disclosed in Patent Document 2, power is supplied from a battery mounted on a vehicle, and the security system is always operated. For this reason, the battery of the parked vehicle is continuously used, and depending on the power consumption of the security device and the remaining amount of the battery, the battery may be consumed during parking and the security system may not function. Things can happen.

  And in a vehicle in which such a security system is not functioning, for example, when a suspicious person ambushes the user of the vehicle in the vicinity of the vehicle, the user cannot obtain information on the suspicious person. Can not be done, and there is a risk of harm from a suspicious person. The same applies to the case where the timing when the suspicious person tries to harm the vehicle and the timing when the user tries to return to the parking position of the vehicle by the guidance of the vehicle position guidance system as described above. In addition, it may be assumed that the suspicious person and the user of the vehicle are in a balance and the user is harmed by the suspicious person.

  For example, in the vehicle position guidance system of Patent Document 1, when a vehicle is parked, the vehicle position is uploaded to a communication station, and information related to the vehicle position is acquired by the mobile communication terminal through the communication station. Since it is comprised, even when the battery of the vehicle is exhausted, information on the vehicle position can be acquired without going through the vehicle. For this reason, in the vehicle position guidance system of Patent Document 1, some users may be guided to the parking position without noticing the system down of the security device due to battery exhaustion, and it is not always necessary to prevent matching with a suspicious person. I couldn't.

The in-vehicle security device 152 is an in-vehicle terminal mounted on the vehicle 150, and includes various devices such as a control device 154, a communication device 156, a position information acquisition device 158, an imaging device 160, a human sensor 172, a tilt sensor 174, and an intrusion sensor 176. It includes a sensor, a speaker 180, a horn 182, a microphone 184, and the like.

  The control device 154 is a computer having a CPU 162 as a processor, a ROM in which a program is written, and a memory 164 including a RAM for temporarily storing map information, image data acquired by the imaging device 160, and the like. The communication device 156, the position information acquisition device 158, the imaging device 160, the human sensor 172, the various sensors such as the tilt sensor 174 and the intrusion sensor 176, the speaker 180, the horn 182 and the microphone 184 that constitute the in-vehicle security device 152 are computers. The control device 154 is controlled by executing a program. The computer program can be stored in an arbitrary computer-readable storage medium in addition to the memory 164.

  In addition, the control device 154 determines the safety around the vehicle 150 based on information transmitted from various sensors including the imaging device 160, the human sensor 172, the tilt sensor 174, the intrusion sensor 176, and the like. When it is determined that the vicinity of the vehicle 150 is in a dangerous state, the determination is transmitted to the mobile communication terminal 102 via the communication device 156. Note that the communication device 156 is, for example, a wireless LAN communication device, and exchanges information with the mobile communication terminal 102 and the external server 141 via an access point of the surrounding public wireless LAN 140 or the like.

  The position information acquisition device 158 is constituted by, for example, a GPS receiver that can receive signals from GPS satellites. The control device 154 acquires the position information output from the position information acquisition device 158 and stores it in the memory 164, and transmits the position information to the mobile communication terminal 102 via the communication device 156. The data is stored in the memory 118 of the control device 106 of the communication terminal 102. Note that the acquired position information of the vehicle 150 can be stored in the external server 141 via the public wireless LAN 140.

  The imaging device 160 includes a plurality of cameras that monitor the periphery of the vehicle 150, for example, four cameras that monitor each of four surrounding directions including the front, rear, right, and left directions of the vehicle. An image captured by each camera is configured as a still image or a moving image, and the captured image is transmitted to the mobile communication terminal 102 via the communication device 156 and stored in the memory 164 of the control device 154.

If a speaker is arranged in the vehicle, even if a suspicious person enters the vehicle 150, the suspicious person can be threatened by using the speaker, for example. The horn 182 is a warning unit that issues a warning to, for example, a suspicious person approaching the vehicle 150 in response to an instruction from the mobile communication terminal 102. The horn 182 may be a horn mounted on a vehicle. Further, instead of the horn 182 or in combination with the horn 182, a hazard lamp, a headlight, a backlight, etc. mounted on the vehicle can be used as warning means for the suspicious person. For example, when a user confirms a suspicious person approaching the vehicle, a headlight or the like is turned on or blinked by remote operation using the mobile communication terminal 102 to thereby detect a suspicious person who is about to approach the vehicle. Can be warned. The microphone 184 is a sound collecting microphone attached to the outside of the vehicle 150 and collects sound generated around the vehicle 150, for example, a voice of a suspicious person.

  The control device 154, the communication device 156, the position information acquisition device 158, the image pickup device 160, various sensors such as the human sensor 172, the tilt sensor 174, and the intrusion sensor 176, the speaker 180, the horn 182, and the microphone 184 are an in-vehicle security device. The device or sensor is not limited to the dedicated device or sensor that configures 152, and may be a device or sensor that configures a car navigation system (not shown) mounted on the vehicle 150, for example.

  Next, a procedure of processing executed by the vehicle position guidance system 100 according to the present embodiment will be described with reference to flowcharts shown in FIGS.

  FIG. 2 is a processing procedure related to acquisition of the parking position of the vehicle 150 executed by the vehicle position guidance system 100. This process ends when the acquired parking position, which is started when the user of the vehicle 150 starts the engine of the vehicle, is transmitted to the mobile communication terminal 102 or the external server 141, for example.

  In this process, it is first determined whether or not the vehicle is parked such as a parking lot (S202). Whether or not the vehicle is parked is, for example, when the engine of the vehicle 150 is stopped, the stopped state continues for, for example, 5 minutes or more, and a signal from the human sensor 172 provided in the vehicle is not detected. It can be judged based on the above (S202: Yes). Note that the determination of whether or not the vehicle is parked is not limited to such a method, and various determination methods can be applied. For example, the determination is made on a car navigation device (not shown) mounted on the vehicle 150. When the control device 154 detects both the arrival signal indicating arrival at the destination and the stop signal indicating engine stop, it may be determined that the vehicle 150 is parked. If it is determined that the vehicle is not parked (S202: No), the process is repeated.

  Subsequently, when it is determined that the vehicle is parked in the parking lot (S202: Yes), the parking position of the vehicle 150 is acquired from the position information acquisition device 158 (S204). The parking position of the vehicle can be acquired using, for example, a position information acquisition device 158 that can detect the vehicle position with an accuracy of about 1 meter, for example. In addition, if such a position information acquisition device 158 with high detection accuracy is used, the altitude of the parking position can be detected with high accuracy even when the vehicle is parked on a desired floor of a self-propelled three-dimensional parking lot. Therefore, the controller 154 can appropriately determine the parking floor based on the detected altitude.

  The acquisition of the parking position of the vehicle in this process is not limited to the above-described method. For example, when the engine of the vehicle 150 is stopped, the communication device 156 of the vehicle 150 to the communication device 110 of the mobile communication terminal 102. It is also possible to use the position information acquired from the position information acquisition device 108 by the mobile communication terminal 102 that has transmitted the engine stop signal and received the stop signal as the parking position. In addition, the imaging device 160 captures the scenery in the parking lot until entering the parking lot and stopping the engine as a moving image, and stores the captured moving image in the memory 164, and a part of the moving image (for example, It is good also as a structure where a user confirms the 30 second animation immediately before parking) as needed, and a parking position is guided. In addition, when the GPS signal reception sensitivity of the position information acquisition device 158 is low, by using this method together, the user can park according to the approximate parking position by GPS and the image at the time of parking by moving images. The position can be accurately grasped.

  In addition, as a method of determining the parking floor of the multi-story parking lot, instead of the method of determining the parking floor from the above-described altitude, for example, a signal from an inclination sensor 174 that configures the in-vehicle security device 152 is used. The parking floor may be determined by counting the number of times the traveling on the inclined surface and the traveling on the horizontal plane after entering the three-dimensional parking lot are repeated. Further, when the GPS signal reception sensitivity is low in the multilevel parking lot, the parking position may be accurately determined by using such a method and the result from the position information acquisition device 158 together. .

  The vehicle parking position obtained by the above-described method is transmitted to the mobile communication terminal 102 through the communication device 156 of the vehicle 150 (S206) and stored in the memory 118 of the control device 106 of the mobile communication terminal 102. Become. Alternatively, the parking position information may be transmitted to the external server 141 connected via the public wireless LAN 140 and stored. When the data is stored in the external server 141, the user of the vehicle 150 can connect to the external server 141 by operating the mobile communication terminal 102, and can confirm the position of the host vehicle as necessary.

  Next, a processing procedure executed by the vehicle position guidance system 100 when the user is guided to the parking position of the vehicle 150 will be described using the flowcharts shown in FIGS. FIG. 3 is a process flow executed by the control device 106 of the mobile communication terminal 102. This process is started at the same time when the user launches a parking position guidance application installed in the mobile communication terminal 102, for example. The application is terminated at the same time as it is terminated. 4 shows a processing flow executed by the control device 154 of the in-vehicle security device 152 mounted on the vehicle 150. This processing is performed by, for example, an activation signal of the security device 152 transmitted from the mobile communication terminal 102. Is started at the same time as receiving the stop signal of the security device 152 transmitted from the mobile communication terminal 102 or when the user reaches the vehicle 150.

  The processing flow shown in FIG. 3 is started when the user launches a parking position guidance application installed in the mobile communication terminal 102. First, an activation signal of the security device 152 is transmitted to the vehicle 150 (S302). As a result, the security device 152 that has been in the sleep state after the engine is stopped is activated by receiving the activation signal, and the processing illustrated in FIG. 4 is started, and the surroundings of the imaging device 160, the human sensor 172, and the like are monitored. The function is activated (S402). Subsequently, the control device 154 of the security device 152 starts imaging of the surrounding situation of the vehicle 150 by the imaging device 160 and monitoring of the vehicle periphery by various sensors such as the human sensor 172 and the tilt sensor 174 (S406).

  Next, in the mobile communication terminal 102, the parking position information stored in the memory 118 of the mobile communication terminal 102 is read, and the parking position read together with the parking lot guide map is displayed on the display screen of the display device 104. It is displayed (S306). If the parking position information is stored in the external server 141, the parking position information is read by accessing the external server 141 via the access point of the public wireless LAN 140. Thus, the user proceeds toward the parking position of the host vehicle while checking the parking position of the host vehicle displayed on the mobile communication terminal 102 on the display device 104.

  Here, when the user is moving toward the parking position of the host vehicle, in the vehicle 150, sensors such as the imaging device 160 and the human sensor 172 that configure the security device 152 monitor the surroundings of the vehicle. When the security device 152 does not detect a suspicious person or the like (S410: No) and the user has not arrived at the vehicle 150 (S414: No), the processing is repeated, and the imaging device 160 and various sensors Monitoring of the surroundings of the vehicle 150 is continued. The mobile communication terminal 102 determines whether or not the suspicious person information transmitted from the security device 152 is received (S310), and the suspicious person information is not received from the security device 152 (S310: No). If the vehicle 150 has not been reached (S314: No), the process is repeated, and the system for receiving suspicious person information from the security device 152 is continued. In addition, when the user arrives at the own vehicle 150 without receiving suspicious person information (S314: Yes, S414: Yes), the guidance to the own vehicle 150 by the vehicle position guidance system 100 ends.

  On the other hand, in the security device 152, for example, when a suspicious person is detected by the imaging device 160 constituting the periphery monitoring function (S410: Yes), the suspicious person is detected in the mobile communication terminal 102. A real-time video image of the suspicious person photographed with the message such as suspicious person information is transmitted (S416). When the mobile communication terminal 102 receives the suspicious person information (S310: Yes), an alarm sound is output from the speaker 130 of the mobile communication terminal 102, and the display screen of the display device 104 displays “Suspicious person detected. Is displayed, and a real-time video of a suspicious person around the host vehicle 150 is displayed (S316).

  Here, in the mobile communication terminal 102, whether or not to make contact with the police or the security company to which the user is subscribed is being executed while the process of displaying the real-time video transmitted from the security device 152 is executed. The confirmation process is executed in parallel (S320). When the user determines that it is necessary to contact the police or the like while checking the video (S320: Yes), the control device 106 searches for the contact information of the police or security company closest to the user's current location. Thus, the user can request the police or the like to take appropriate measures against the suspicious person.

  In addition, when the video transmitted from the security device 152 shows a mischievous situation such as a small child touching the user's vehicle 150, the user needs to contact the police or the like. In such a case, for example, a voice such as “Do not touch the car!” Is input to the microphone 120 of the mobile communication terminal 102, and the voice is It can transmit to the vehicle 150 and can be alerted by voice to the children who are mischievous through warning means comprising the speaker 180 mounted on the vehicle 150 (S328: Yes, S332, S420: Yes, S424). ). Instead of this, or in combination with this, the horn 182 and warning means such as horn, headlight, backlight, hazard lamp, etc. mounted on the vehicle are activated by remote control using the mobile communication terminal 102. May be. Note that such warning means can be selected as appropriate based on remote control instructions from the user, detection information from the imaging device 160, the human sensor 172, the intrusion sensor 176, and the like. For example, when a suspicious person is detected by a front camera mounted in front of the vehicle 150 and the user selects a light or the like on the mobile communication terminal 102, the security device 152 operates the headlight to warn the suspicious person. be able to. In addition, when the intrusion sensor 176 detects the intrusion of a suspicious person, a warning sound can be output from a speaker in the vehicle.

  In the security device 152, for example, when a plurality of human sensors 172 operate simultaneously, or when the presence of a plurality of suspicious persons can be recognized in an image captured by the imaging device 160, a plurality of suspicious people are detected. Since it is estimated that the person is present around the vehicle 150, the control device 154 of the security device 152 determines that the vehicle periphery is in a dangerous situation that cannot be handled by one user (S428: Yes), In order to urge the user not to approach the vehicle 150, a danger signal is transmitted to the mobile communication terminal 102 (S432). And when the said danger signal is received in the mobile communication terminal 102 (S336: Yes), the control apparatus 106 of the mobile communication terminal 102 stops the guidance of the user to the own vehicle 150, for example, the guard room of the said parking lot, By searching the Internet for information on the nearest safe place such as a management room of a shopping center attached to the parking lot via the public wireless LAN 140 and changing the information to a guide to the safe place, the user can be Guide to the safe place (S340).

  Here, in FIG. 3, when the danger signal is received (S336: Yes), the user is guided to a safe place such as a security room of the parking lot, and the process ends when the safe place is reached. (S344: Yes). When the danger signal is not received (S336: No), the control device 106 of the mobile communication terminal 102 guides the user to the own vehicle and keeps the danger signal until reaching the own vehicle. This process ends when the process of determining whether or not the vehicle has been received is repeated (S348: No) and the vehicle reaches the host vehicle (S348: Yes). In FIG. 4, the process related to the determination of whether or not the vehicle periphery is dangerous (S428) is repeatedly executed until the user arrives at the vehicle 150 (S440: No). Then, when the user arrives at the vehicle 150 (S436: Yes), or when an end signal is transmitted from the mobile communication terminal 102 possessed by the user, this processing ends.

  Thus, in the vehicle position guidance system 100 according to the present embodiment, the location where the guidance to the vehicle 150 is started in order to activate the security device 152 of the vehicle 150 when the position guidance to the parked vehicle is requested. Until the parking position of the host vehicle is reached, the security system 152 mounted on the vehicle 150 can be reliably operated. Thereby, for example, when there is a suspicious person around the host vehicle, the security device 152 can detect the suspicious person and transmit the detection information to the mobile communication terminal 102 possessed by the user. . When the user is being guided to the parking position of the vehicle 150 by the vehicle position guidance system 100, if the vehicle 150 is harmed by a suspicious person, an alarm sound output from the mobile communication terminal 102 Since it is possible to stop walking to the vehicle 150 by coming into contact with the suspicious person information, it is possible to prevent the suspicious person from being put together. In addition, the user can take appropriate measures such as contacting the police at a place away from the suspicious person while confirming the appearance and behavior of the suspicious person on the display device 104 of the mobile communication terminal 102.

  In addition, the vehicle position guidance system 100 according to the present embodiment stops the guidance to the host vehicle when the host vehicle is in a dangerous situation where the periphery of the host vehicle is surrounded by a plurality of suspicious persons, for example. In addition, since the destination changing function that can start guidance to a safe place other than the vehicle is provided, the safety of the user can be further ensured.

  In the present embodiment, the parking position guidance request is made by the user starting up an application installed in the mobile communication terminal 102 and the parking position guidance is started. The start of is not limited to such a case. For example, in a small parking lot, when the user can store the parking position, it may be assumed that the user does not start an application, and the vehicle position guidance system 100 does not function effectively. Cases are also conceivable. In such a case, the processing flow shown in FIGS. 3 and 4 is started with the application for parking position guidance being always started in the background and triggered by an operation that proceeds toward the parked vehicle. May be.

  For example, when the control device 106 detects a reduction in the distance between the current position of the user and the parking position of the vehicle stored in the memory of the mobile communication terminal 102, it is determined that the operation is toward the parked vehicle. It is good also as a structure which starts the processing flow shown to 3 and 4 and the security apparatus 152 of a vehicle is started. Also, when shopping at a shopping center adjacent to the parking lot or paying a parking fee, the flow shown in FIGS. 3 and 4 is started when the mobile communication terminal 102 is used for payment. The vehicle security device 152 may be activated.

  Moreover, the vehicle position guidance system 100 according to the present embodiment is not limited to the large-scale parking lot described above, and can be applied to, for example, a case where the vehicle 150 is parked in a parking lot near the user's home. For example, when the user goes out of the house, the processing flow shown in FIGS. 3 and 4 may be started and the vehicle security device 152 may be activated. In addition, when the going out is not going out using a vehicle, a configuration is adopted in which an off signal is transmitted from the mobile communication terminal 102 to the security device 152 after the elapse of a predetermined time after activation, and the security device 152 is stopped. Also good.
