A headlight 11 that emits light in front of the vehicle 1 is arranged in the front part of the vehicle 1 . The headlight 11 of the present embodiment is a twin-lens type headlight unit that includes a right light irradiation section 11R and a left light irradiation section 11L symmetrically. However, a single-lens type headlight unit, a three-lens type headlight unit, or a left-right asymmetric two-lens type headlight unit can also be employed.

The front part of the vehicle 1 is covered with a front cowl 12, and the front side part of the vehicle 1 is covered with a pair of left and right side cowls 14. A screen 13 is arranged above the front cowl 12 . The screen 13 is a windshield that reduces the wind pressure applied to the rider during running, and is made of, for example, a transparent resin member.

A pair of left and right side mirror units 15 are arranged on the sides of the front cowl 12 . A side mirror (not shown) is supported by the side mirror unit 15 so that the rider can visually recognize the rear.

In the case of this embodiment, the front cowl 12 is composed of cowl members 121-123. The cowl member 121 extends in the Y direction to constitute the main body of the front cowl 12 , and the cowl member 122 constitutes the upper portion of the cowl member 121 . The cowl member 123 is spaced downward from the cowl member 121 .

Between the cowl member 121 and the cowl member 123 and between the pair of left and right side cowls 14, an opening is formed to expose the headlight 11. The upper edge of this opening is defined by the cowl member 121, and the lower edge is defined by the cowl member 121.

External communication devices 107 include GPS 134, near field wireless device 135, and key authentication communication device 136, for example. Of course, each component may include other configurations.

The control unit 101 includes a processor represented by a CPU. The storage unit 102 stores programs executed by the processor, data used by the processor for processing, and the like. Note that the storage unit 102 may be incorporated inside the control unit 101 . The control unit 101 is connected to other components 102 to 107 via signal lines such as buses, can transmit and receive signals, and controls the vehicle 100 as a whole.

For example, the control unit 101 acquires the detection result of the radar unit 16B of the external monitoring device 103, constantly recognizes targets and road conditions around the vehicle 100, and detects objects approaching the vehicle 100. be able to. In addition, the control unit 101 can use the imaging unit 16A to photograph and record road conditions, approaching objects, etc. during travel. The control unit 101 can store image data captured by the imaging unit 16A in the storage unit 102, and can also transmit the data to an external device using an external communication device (not shown). Also, the control unit 101 acquires various information via the GPS 134 , the short-range wireless device 135 , and the key authentication communication device 136 . GPS 134 acquires the current position of host vehicle 100 . The short-range wireless device 135 transmits a signal according to the danger state of the own vehicle 100, which will be described later, within a predetermined distance via short-range wireless communication. Near-field wireless communication may be any communication method that enables communication within a predetermined range, such as wireless LAN (Wi-Fi), Bluetooth, NFC, and infrared communication. The communication range can be set as an area including a radius of 5 m to 20 m from the own vehicle 100, for example. The signal is received by one or more other vehicles 200 located within a predetermined range from host vehicle 100 . Further, the control unit 101 performs short-range wireless communication with an authentication key (key) 220 believed to be possessed by an approaching person approaching the vehicle 100 via the key

authentication communication device

136, and 220 is authenticated as to whether or not the user is the authorized owner of own vehicle 100 . The short-range wireless communication between the key authentication communication device 136 and the authentication key 220 may or may not be the same communication method as the short-range wireless device 135 .

The control unit 101 can control each actuator included in the manipulator 105 . Further, in the case of the present embodiment, the control unit 101 monitors inputs to each actuator in order to detect a dangerous state of the own vehicle 100 by a suspicious person, which will be described later. Furthermore, the control unit 101 detects a dangerous state of the vehicle 100 by a suspicious person based on the detection results of various vehicle-mounted sensors 106 . Here, the dangerous state of the vehicle 100 by a suspicious person indicates the degree or possibility of a crime against the vehicle 100 by an approaching person whose authentication via the key authentication communication device 136 has failed, that is, a suspicious person. be. For example, in this embodiment, the dangerous state is classified into possible danger, danger preparation, danger, and danger avoidance according to the difference in degree. Details will be described later.

Next, the configuration of the other vehicle 200 will be explained. The other vehicle 200 indicates one or more vehicles within a predetermined range from the position of the own vehicle 100, and each vehicle has various configurations. Only the configuration will be explained. Therefore, other vehicle 200 may include other configurations in addition to the configuration described here. Other vehicle 200 includes control unit 201 , storage unit 202 , external communication device 203 , and imaging unit 204 . The external communication device 203 includes a GPS 205 , a short-range wireless device 206 and a data transmission section 207 . Imaging unit 204 includes camera 208 and drive recorder 209 .

The control unit 201 includes a processor represented by a CPU. The storage unit 202 stores programs executed by the processor, data used by the processor for processing, and the like. Note that the storage unit 202 may be incorporated inside the control unit 201 . The control unit 201 is connected to

other components

203 and 204 via signal lines such as buses, can transmit and receive signals, and controls the other vehicle 200 as a whole.

The control unit 201 can store the imaging data captured by the imaging unit 204 in the storage unit 202, and can also transmit the data to the external device 211 via the wide area network using the data transmission unit 207 of the external communication device 203. Also, the control unit 201 acquires various types of information via the GPS 205 and the short-range wireless device 206 . GPS 205 acquires the current position of other vehicle 200 . For example, it is possible to acquire the position of the other vehicle 200 when the camera 208 of the imaging unit 204 takes an image, and add the position information to the imaging data. The short-range wireless device 206 receives a signal according to the dangerous state transmitted from the own vehicle 100 via short-range wireless communication. Near-field wireless communication may be any communication method that enables communication within a predetermined range, such as wireless LAN (Wi-Fi), Bluetooth, NFC, and infrared communication. As the communication range, for example, an area including a radius of 5 m to 20 m from the other vehicle 200 can be set.

The external device 211 receives, via the wide area network, data relating to the shooting site, such as image data transmitted from each vehicle, and stores the data in the data storage unit 212 . The data stored in the data storage unit 212 is later used by a predetermined agency to analyze and investigate crimes.

<Detection of approaching person>
FIG. 4 shows a diagram for explaining a mechanism for detecting an approaching person to the own vehicle 100 according to this embodiment. Circles R1 and R2 indicate a range of a predetermined radius from the vehicle 100. FIG. For example, R1 is set between 5m and 20m, and R2 is set within 5m. 400a to 400c represent persons approaching the own vehicle 100 in the direction of the arrow.

As indicated by 410, own vehicle 100 uses radar 111 and laser 112 to detect objects approaching own vehicle 100. Depending on the performance of the radar 111 and laser 112, R1, for example, a person 400a located at a location exceeding a radius of 20 m from the own vehicle 100 can also be detected. At the position of person 400 a , it is not determined that the person is approaching vehicle 100 .

A person 400b indicates a person located within the range of R1 but outside the range of R2, for example, within the range of 5m to 20m from the own vehicle. Note that the own vehicle 100 does not immediately judge the person 400b as an approaching person at the timing when the person 400b enters the range of R1. This is to prevent erroneous detection of a person or the like passing by the vehicle 100 as a person approaching the vehicle 100 . Also, the person 400b who is within the range of R1 but out of the range of R2 is basically not judged as an approaching person. However, if the person 400b who has entered the range of R1 moves within a predetermined period of time, such as by shortening the distance from the own vehicle 100, it may be determined as an approaching person.

A person 400c indicates a person located within the range of R2, for example, within 5m from the own vehicle. The host vehicle 100 determines that a person is an approaching person when the person enters the range of R2. Further, when own vehicle 100 determines that the person is approaching, it performs short-range wireless communication with authentication key 220 that person 400c may possess via key authentication communication device 136, and the approaching person is authorized to own vehicle 100. to authenticate whether you are the owner of Here, if the person 400c does not possess the authentication key 220, the authentication information cannot be acquired from the authentication key 220 in the first place, and the authentication process fails. In such a case, the vehicle 100 determines that the approaching person 400c is a suspicious person. Note that the authentication processing using these short-range wireless communication may be triggered by identifying an approaching person. On the other hand, the authentication process may be automatically executed, the range of the short-range wireless communication is set within the range of R2, for example, within 5 m, and a signal for establishing the short-range wireless communication is constantly transmitted. There may be. As a result, for example, even when an approaching person cannot be detected by the radar 111 or the like due to an obstacle around the own vehicle 100, authentication can be performed when the approaching person is detected by the radar 111 when the own vehicle 100 is considerably approached. If the processing is not successful, the approaching person can be immediately identified as a suspicious person.

<Warning process>
FIG. 5 is a flowchart showing the procedure of warning processing executed by the control unit 101 of the own vehicle 100 according to the approaching state of the suspicious person according to this embodiment. The processing described below is realized, for example, by the CPU of the control unit 101 reading a program held in the ROM or the storage unit 102 into the RAM and executing the program. The number following S indicates the step number of each process. Here, the approaching state of a suspicious person indicates a state of danger to the own vehicle 100 by a suspicious person.

First, in S501, the control unit 101 of the own vehicle 100 executes authentication processing of an approaching person approaching the own vehicle 100, as described using FIG. Specifically, the control unit 101 transmits a signal for establishing short-range wireless communication using the key authentication communication device 136 within a predetermined distance range. Authentication information is obtained from the authentication key 220 and authentication processing is executed.

Subsequently, in S502, the control unit 101 determines whether or not the authentication process with the authentication key 220 has succeeded. If the authentication process is successful, the process proceeds to S509, the control unit 101 proceeds to start control of the own vehicle 100, and ends this flowchart. On the other hand, if the authentication process has not succeeded, the control unit 101 identifies the approaching person as a suspicious person and advances the process to S503. Here, the case where the authentication process is not successful means the case where the close person does not have the authentication key in the first place and the short-range wireless communication is not established, or the near-field wireless communication is established but the subsequent authentication process is performed. This includes the case where the owner of the own vehicle 100 cannot be determined to be the authorized owner.

In S503, the control unit 101 determines whether or not an approaching person whose authentication processing has not succeeded has approached within a predetermined distance from the own vehicle 100, based on the output of the radar unit 16B. More specifically, the control unit 101 determines whether an approaching person identified as a suspicious person has approached within 3 m from the own vehicle 100 based on the output result of the radar 111, for example. If it approaches, the process proceeds to S504. On the other hand, if it is not approaching, the determination of S503 is repeated. If the person does not approach within the predetermined distance after the predetermined time has passed, or if the person moves away from the range of R2, it is determined that there is no possibility of identifying the suspicious person, and the repeated determination of S503 ends. You may

At S504, the control unit 101 determines that the vehicle 100 may be in danger from a suspicious person. Here, the possibility of danger indicates that there is an increased possibility that self-vehicle 100 will be stolen or mischievous by a suspicious person. Subsequently, in S505, the control unit 101 issues an alarm according to the first pattern. More specifically, the control unit 101 turns on the warning light using at least one of the lighting bodies such as the headlight 11, the taillight 117, and the blinker 115. FIG.

Next, in S506, the control unit 101 determines whether or not at least one of detection by the in-vehicle sensor 106 and input to the operator 105 has occurred. If it has not occurred, the determination of S506 is repeated periodically. Note that when a predetermined time has passed or when the approaching person has left the range of R1 or R2, it may be determined that there is no longer a possibility that the own vehicle 100 will be subjected to a criminal act, and the determination process may be terminated. . On the other hand, if either occurs, the process proceeds to S507, and the control unit 101 determines that the host vehicle 100 is under criminal activity, that is, is in danger. Subsequently, in S508, the control unit 101 issues an alarm with a second pattern different from the first pattern, and terminates the process. More specifically, the control unit 101 causes the horn 118 or the like to generate a warning sound, for example, in addition to or in place of the warning by the lamp body in the first pattern. As described above, according to the present embodiment, the behavior of the suspicious person is monitored by switching the warning pattern using sound or light according to the approach state of the approaching person identified as the suspicious person to the own vehicle 100 . It is possible to raise awareness of the fact that It is desirable that the warning be continued until it is determined that there is no danger of a criminal act or a predetermined input is made. It should be noted that the terms "first pattern" and "second pattern" used here do not necessarily correspond to the "first pattern" and "second pattern" described in the claims. . In this specification, the same applies to other terms, but "first", "second", and "third" merely indicate that they are different from each other.

<Modified example of warning processing>
FIG. 6 is a flow chart showing a modification of the warning process of FIG. The processing described below is realized, for example, by the CPU of the control unit 101 reading a program held in the ROM or the storage unit 102 into the RAM and executing the program. The number following S indicates the step number of each process. Further, the same step numbers are assigned to the same processes as in FIG. 5, and the description thereof is omitted.

When at least one of detection by the in-vehicle sensor 106 and input to the operation element 105 occurs in S506, the process proceeds to S601, the control unit 101 determines that it is a risk preparation time, and starts counting the number of occurrences. Here, the danger preparation time indicates a state in which the possibility of danger to the own vehicle 100 is higher than the danger possibility time. Subsequently, in S602, the control unit 101 determines whether or not the number of occurrences of at least one of the detection by the in-vehicle sensor 106 and the input to the operator 105 has reached a predetermined number. If the predetermined number of times has been reached, the process proceeds to S507; otherwise, the determination of S602 is periodically repeated. It should be noted that if a predetermined time has elapsed since the counting was started, or if the target approaching person has left the range of R1 or R2, it may be determined that there is no more danger to the own vehicle 100, and the process may end. good. In S507, the control unit 101 determines that the host vehicle 100 is in danger, and thereafter executes the same processing as the processing in FIG.

Note that here, the warning was not issued when it was determined that it was a danger preparation time, but the warning may be issued at this timing as well. In that case, it is desirable to have different alarm patterns in each of the possibility of danger, danger preparation, and danger. For example, when it is determined that there is danger, the lighting is turned on, when it is determined that danger is to be prepared, the lighting is flashed and the horn 118 is used to temporarily generate a warning sound, and when it is determined that there is danger, the lighting is turned on. A warning sound may be generated continuously while blinking the body.

<Second embodiment>
A second embodiment of the present invention will be described below. In the first embodiment described above, flexibly switching the alarm pattern by sound or light according to the approach state of the vehicle 100 by a suspicious person has been described. Furthermore, according to the present invention, the crime scene is suitably photographed in cooperation with the other vehicle 200 in accordance with such an approaching state, and the photographed image serving as evidence is recorded. In more detail, it is characterized by switching the signal transmitted from own vehicle 100 according to the approach state with respect to own vehicle 100 of a suspicious person. Further, the other vehicle 200 controls the activation state of an imaging unit such as a camera and the start of imaging according to the received signal. Note that this embodiment may be configured to be added to the warning processing described in the first embodiment, or may be configured to be performed independently.

<Relationship between own vehicle and other vehicle>
FIG. 7 shows a diagram for explaining the relationship between the host vehicle 100 and the other vehicle 200 according to this embodiment. Circles R1 and R2 indicate a range of a predetermined radius from the vehicle 100. FIG. For example, R1 is set between 5m and 20m, and R2 is set within 5m. A person 400 c indicates a suspicious person who has approached the own vehicle 100 . 200a to 200c denote other vehicles having imaging units such as cameras.

As indicated by 700 , own vehicle 100 transmits a signal informing the danger of own vehicle 100 within a predetermined distance according to the approaching state of a suspicious person to own vehicle 100 . The signal is transmitted, for example, within a range of R1, for example within a radius of 5 m to 20 m. Therefore, the signal transmitted from own vehicle 100 is received by each of

other vehicles

200a, 200b, and 200c located within the range of R1. On the other hand, other vehicles located beyond the range R1 from own vehicle 100 cannot receive the signal from own vehicle 100. FIG.

Own vehicle 100 transmits a signal in response to at least one of the approaching state of a suspicious person to own vehicle 100, that is, the danger potential state, danger preparatory state, and danger state. For example, the own vehicle 100 transmits a signal indicating the danger possibility of the own vehicle 100 in the dangerous state, and a signal indicating that the own vehicle 100 is in danger (corresponding to the first signal) in the dangerous state. ). Alternatively, the own vehicle 100 transmits a signal (corresponding to a second signal) indicating that the own vehicle 100 is in a danger preparation state in the danger preparation state, and transmits a signal indicating that the own vehicle 100 is in the danger preparation state. A signal may be sent to indicate that there is.

On the other hand, the other vehicles 200a to 200c control activation of their own imaging units according to the received signal. For example, when the other vehicles 200a to 200c receive the signal indicating the possibility of danger or the signal indicating the time of risk preparation, they activate the imaging unit to prepare for photographing, and when they receive the signal indicating the time of danger, You may make it start the imaging|photography using an imaging unit. Further, the other vehicles 200a to 200c transfer the photographed data to the external device 211 via the data transmission section 207. FIG. In the external device 211, the imaging data transferred from each of the other vehicles 200 is stored in the data storage unit 212 and accumulated. In addition, the positional information acquired by GPS205 at the time of imaging|photography may be added to the imaging data transferred from the other vehicle 200. FIG. This allows for more accurate crime scene evidence to be recorded. Further, the other vehicles 200a to 200c grasp the distance from the own vehicle 100 according to the signal strength of the received signal, and, for example, only when they determine that they are located within the range R2 from the own vehicle 100, shoot. you can go As a result, only other vehicles located relatively close to the host vehicle 100 can take pictures, and useless pictures can be reduced.

Note that the own vehicle 100 may change the transmission range according to the signal to be transmitted. For example, the vehicle 100 may transmit signals within R1 during potential danger conditions and within R2 during danger conditions. As a result, in actual photographing, only other vehicles that are closer to the vehicle may be photographed, and photographing of other vehicles that are relatively distant from the vehicle may be avoided. This is because there is a high possibility that an obstacle exists between the subject vehicle and the subject vehicle from a relatively distant location, so such useless photography can be reduced.

<Warning processing>
FIG. 8 is a flow chart showing the procedure of warning processing executed by the control unit 101 of the own vehicle 100 according to the approaching state of the suspicious person according to this embodiment. The processing described below is realized, for example, by the CPU of the control unit 101 reading a program held in the ROM or the storage unit 102 into the RAM and executing the program. The number following S indicates the step number of each process. 5 and 6 are assigned the same step numbers, and descriptions thereof are omitted.

In S504, when an approaching person who has not been successfully authenticated approaches within a predetermined distance L1 from the own vehicle 100, the process proceeds to S801, and the control unit 101 determines that there is a possibility of danger and indicates the possibility of danger. A signal is sent, for example, within R1 to start counting the number of occurrences. Subsequently, in S602, the control unit 101 determines whether or not the number of occurrences of at least one of the detection by the in-vehicle sensor 106 and the input to the operator 105 has reached a predetermined number. If the predetermined number of times has been reached, the process proceeds to S802; otherwise, the determination of S602 is periodically repeated. It should be noted that if a predetermined time has elapsed since the counting was started, or if the target approaching person has left the range of R1 or R2, it may be determined that there is no more danger to the own vehicle 100, and the process may end. good. In S802, the control unit 101 determines that the host vehicle 100 is in danger, transmits a signal indicating the danger within the range of R1 or R2, and then executes the same processing as the processing in FIG.

In this flowchart, when it is determined that there is a possibility of danger in S601, no signal indicating that effect is transmitted, but such a signal may be transmitted at this timing as well. Also, it is desirable that each of these signals be transmitted continuously or periodically. As a result, even when the own vehicle 100 is moved, it is possible to transmit a signal to another nearby vehicle at the destination. This is because the other vehicle 200 cannot continuously grasp the dangerous state of the own vehicle 100 only by receiving the signal once, and therefore, for example, it cannot appropriately determine the end timing of the photographing.

<Photography processing of other vehicles>
FIG. 9 is a flow chart showing a processing procedure of photographing processing of the other vehicle 200 according to this embodiment. The processing described below is realized, for example, by the CPU of the control unit 201 reading a program held in the ROM or the storage unit 202 into the RAM and executing the program. The number following S indicates the step number of each process. Here, as shown in FIG. 8, the case where own vehicle 100 transmits a danger preliminary signal and a danger signal will be described. The same processing is performed when a danger possibility signal is received instead of the danger preliminary signal.

In S901, the control unit 201 receives a danger preliminary signal (or danger possibility signal) from the own vehicle 100 via the short-range wireless device 206. Subsequently, in S902, the control unit 201 activates at least one of the camera 208 of the imaging unit 204 and the drive recorder 209, and executes preparation processing for photographing.

Next, in S<b>903 , the control unit 201 receives a danger signal from the own vehicle 100 via the short-range wireless device 206 . Subsequently, in S904, the control unit 201 starts shooting with the imaging unit 204 activated in S902. These imaging operations may be performed continuously for a predetermined period of time and periodically, or, for example, in the case of receiving a signal periodically, if the signal is not received for a predetermined period of time, the imaging may be terminated. The details of the determination of whether or not to end shooting will be described later.

When the shooting ends, the control unit 201 records the captured image data in the storage unit 202 in S905. Alternatively, it may be stored in a memory card (not shown) or the like. As a result, the memory card can be submitted to an investigative agency that investigates crimes, thereby improving the portability of data and effectively utilizing the storage area. Also, the control unit 201 may transmit the imaging data to the external device 211 via the data transmission unit 207 . Accordingly, the imaged data is held in the storage unit 212 of the external device 211, and the imaged data of each vehicle can be collectively managed.

<Modification>
Various modifications are possible without intending to limit the present invention to the above embodiment. Various modifications will be described below with reference to the drawings. It should be noted that the following modifications can be applied alternatively or additionally to the first and second embodiments, and alternatively or additionally to other modifications to the extent possible. can.

<Modification of danger signal transmission>
In the above-described embodiment, the configuration for transmitting a signal according to the approach state of a suspicious person to the own vehicle 100 has been described with reference to FIG. However, an emergency signal or the like may be transmitted when other conditions are satisfied. FIG. 10 is a flow chart showing a modification of the processing procedure when the own vehicle 100 transmits the danger signal. This flowchart shows the processing executed when the GPS 134 is powered off. The processing described below is realized, for example, by the CPU of the control unit 101 reading a program held in the ROM or the storage unit 102 into the RAM and executing the program. The number following S indicates the step number of each process.

In S1001, the control unit 101 determines whether or not the power to the GPS 134 was cut off according to a normal procedure. Here, the normal procedure refers to a procedure in which the power supply is cut off by disabling the function of the GPS 134 according to a predetermined procedure on an operation panel (not shown) or the like. On the other hand, the illegal procedure is, for example, when a suspicious person steals the own vehicle 100, the power supply is cut off by physically disconnecting the power cable of the GPS 134 because the position of the vehicle after the theft cannot be grasped. indicates the case. Therefore, when the input of the position information from the GPS 134 stops without performing the regular procedure, the control unit 101 determines that the power supply to the GPS 134 has been cut off by a procedure different from the regular procedure. In that case, the process advances to S1002, and if it is determined that the normal procedure has been performed, this flowchart ends.

At S1002, the control unit 101 determines that the vehicle 100 is in danger by a suspicious person, transmits a signal indicating danger within the range of R1 or R2, and terminates this flowchart. Here, the danger signal may be transmitted regardless of whether the suspicious person is identified, or the danger signal may be transmitted only when the suspicious person approaching the own vehicle 100 is identified. may The other vehicle 200 that has received the emergency signal executes the processes of S903 to S905 described with reference to FIG.

Also, a suspicious person may disconnect the short-range wireless device 135 of the own vehicle 100 . In such a case, the other vehicle 200 starts photographing when it stops receiving danger signals such as danger potential signals, danger preliminary signals, and danger signals periodically transmitted from the own vehicle 100. You may make it Thereby, even when the communication device is disconnected, it is possible to start shooting at an appropriate timing.

<Modified Example 1 of Shooting Processing>
In the above-described embodiment, the configuration for switching and transmitting the signal according to the approach state of the suspicious person to the own vehicle 100 has been described with reference to FIG. 9 . However, the host vehicle 100 may transmit a constant signal (hereinafter referred to as a danger signal) without switching the signal according to the approach state. FIG. 11 is a flow chart showing a modified example of the processing procedure of the photographing processing of the other vehicle 200. As shown in FIG. The processing described below is realized, for example, by the CPU of the control unit 201 reading a program held in the ROM or the storage unit 202 into the RAM and executing the program. The number following S indicates the step number of each process. Further, the same step numbers are attached to the same processing as in FIG. 9, and the description thereof is omitted.

At S1101, the control unit 201 receives the danger signal from the own vehicle 100. Subsequently, in S1102, the control unit 201 determines whether or not the distance to the own vehicle 100 is within the range of R2, for example, within 5 m. For example, the control unit 201 may determine the distance to the own vehicle 100 according to the signal strength received in S1101, or may measure the distance to the own vehicle 100 using a radar unit (not shown). If it is within the range of R2, proceed to S904; otherwise, proceed to S1103d. After proceeding to S904, the control unit 201 starts shooting and executes the same processing as in FIG.

On the other hand, in S1103, the control unit 201 determines whether or not the distance to the own vehicle 100 is within the range of R1, for example, within 20m. The distance to own vehicle 100 is determined in the same manner as in S1102. If it is within the range of R1, the process proceeds to S902; otherwise, the flow chart ends.

In S902, the control unit 201 activates the imaging unit to prepare for imaging, and returns the process to S1101. After that, when the danger signal is periodically received, the imaging unit is placed in a standby state until it is positioned within the range of R2. As described above, in the modification, after the other vehicle 200 receives a danger signal from the own vehicle 100 indicating danger, the distance to the own vehicle 100 is measured, and the imaging unit is activated according to the measurement result to set the vehicle in the standby state. or to start shooting.

<Modified Example 2 of Shooting Processing>
Next, another modified example in the case of determining whether or not another vehicle 200 starts photographing will be described. FIG. 12 explains the processing related to the end of the photographing processing of the host vehicle 100 and the other vehicle 200. FIG. FIG. 12A shows the processing after the host vehicle 100 has transmitted the danger signal, and FIG. 12B shows the processing after the other vehicle 200 receives the danger signal. The processing described below is realized by, for example, CPUs of the

control units

101 and 201 reading programs held in the ROM and the

storage units

102 and 202 into the RAM and executing the programs. The number following S indicates the step number of each process.

First, the processing of own vehicle 100 will be described. In S1201, the control unit 101 transmits a danger signal. The danger signal here corresponds to the signal transmitted in S801 or S802. Alternatively, the vehicle 100 may transmit a constant signal without switching the signal according to the approaching state of the suspicious person. Furthermore, the control unit 101 starts timing a predetermined time.

Next, in S1202, the control unit 101 determines whether or not the time that started measuring in S1201 has passed a predetermined time, for example, one minute. If the predetermined time has elapsed, the process proceeds to S1203, and if not, the process returns to S1201 to continue transmitting the danger signal. In S1203, the control unit 101 stops transmitting the danger signal and ends this flowchart.

Next, the processing of the other vehicle 200 will be explained. In S1211, the control unit 201 receives a danger signal from the own vehicle 100, activates the imaging unit, and puts it in a standby state. Also, the control unit 201 starts timing a predetermined time. Subsequently, in S1212, the control unit 201 determines whether or not the clocked time has passed a predetermined time, for example, 1 minute. After the predetermined time has elapsed, the process advances to step S1213, and the control unit 201 starts photographing by the imaging unit. As described above, in this modified example, the own vehicle 100 stops transmitting the danger signal after a predetermined period of time has passed, and the other vehicle 200 receives the danger signal and starts shooting after a predetermined period of time has passed. Note that it is desirable that the other vehicle 200 starts shooting when it continues to receive the danger signal even after the predetermined time has passed. As a result, it is possible to reduce erroneous operations such as when the transmission of the danger signal is stopped when the danger is avoided.

<Modified Example 3 of Shooting Processing>
Next, a modification will be described in which another vehicle 200 determines whether to stop photographing and adds the position information at that time to the photographed data. FIG. 13 is a flowchart showing another processing procedure of photographing processing by the other vehicle 200. FIG. The processing described below is realized, for example, by the CPU of the control unit 201 reading a program held in the ROM or the storage unit 202 into the RAM and executing the program. The number following S indicates the step number of each process. Further, the same step numbers are attached to the same processing as in FIG. 9, and the description thereof is omitted.

When photographing is started in S904, in S1301, the control unit 201 uses the signal strength of the danger signal received from the own vehicle 100 or a radar unit (not shown) to determine whether the distance from the own vehicle 100 is within a predetermined distance, for example, the range of R2. It is judged whether it is within 5m. If it is within the predetermined distance, the determination in S1301 is repeated. If it is not within the predetermined distance, for example, if it is determined that the other vehicle 200 is not within the range R2 from the own vehicle 100, the process proceeds to S1302.

In S1302, the control unit 201 stops shooting. Subsequently, in S1303, the control unit 201 acquires position information using the GPS 205 and adds it to the imaging data captured after S1301. After that, in S905, the control unit 201 stores the imaging data in the storage unit 202, transmits it to the external device 211 via the data transmission unit 207, and ends this flowchart.

FIG. 14 is a diagram showing the effect of the flowchart in FIG. 100a to 100c indicate own vehicles. Here, the stolen own vehicle 100 is shown moving in the order of 100a, 100b, and 100c. 200a to 200c indicate other vehicles. Circles R1 and R2 indicate a range of a predetermined radius from the vehicle 100a-100c. For example, R1 is set between 5m and 20m, and R2 is set within 5m. Dotted lines R1 and R2 indicate radii from the host vehicle 100a. Solid lines R1 and R2 indicate radii from the host vehicle 100b. R1 and R2 indicated by dashed lines indicate radii from the host vehicle 100c.

When the control described above is performed using FIG. 13, the other vehicle 200a is located within the range indicated by the dotted line R2 at the position of the own vehicle 100a, so that it is photographed. On the other hand, when the

subject vehicle

100b or 100c moves to the position, the other vehicle 200a is not positioned within the range of R2 indicated by the solid line or the one-dot chain line, so the photographing ends. Similarly, the other vehicle 200b shoots at the position of its own vehicle 100b, but finishes shooting at the position of its own vehicle 100c. Also, although the other vehicle 200c takes the image at the position of the own vehicle 100c, the image taking ends when the own vehicle 100c moves further and the other vehicle 200c is out of the range of R2. When the photographing is finished, each of the other vehicles 200a to 200c obtains the positional information, adds it to the photographed data, stores it, and transmits it to the external device 211. FIG.

In this way, after each of the other vehicles 200a to 200c receives the danger signal, it determines the distance from the own vehicle 100 and determines the end of shooting. For example, when the imaging unit of the other vehicle 200 is provided in front of the vehicle, it is possible to photograph a predetermined range in the forward direction, but it is not possible to photograph positions beyond that range. In other words, since the other vehicle 200 has a limited imaging range, it is desirable to end the imaging by determining that the own vehicle 100 cannot be imaged when the distance from the own vehicle 100 is to some extent. It is desirable that this distance can be changed by setting based on the performance of the camera. If the shooting direction of the camera can be changed, it is possible to set a wider shooting range. By determining the end of photographing by the other vehicle 200 in this way, the control of the own vehicle 100 can be simplified and unnecessary photographing can be avoided.

<Judgment of end of shooting process>
Next, a modified example in which it is determined that the host vehicle 100 has avoided danger and a signal is transmitted, and when the other vehicle 200 receives the signal, the other vehicle 200 ends the image capturing, and adds the position information at that time to the captured image data. explain. FIG. 15 explains processing related to the end of photographing processing of own vehicle 100 and other vehicle 200 . FIG. 15A shows processing when own vehicle 100 is determined to be in a dangerous state, and FIG. 15B shows processing after other vehicle 200 starts photographing. The processing described below is realized by, for example, CPUs of the

control units

101 and 201 reading programs held in the ROM and the

storage units

First, the processing of own vehicle 100 will be described. In S1501, the control unit 101 determines that the host vehicle 100 is in danger by a suspicious person and transmits an emergency signal. Note that the determination of these dangerous states is the same as the control described with reference to FIG. 8, so description thereof will be omitted. When the danger signal is transmitted, in S1502 the control unit 101 issues an alarm using the second pattern as described above.

After that, in S1503 to S1505, the control unit 101 determines whether the dangerous state of the own vehicle 100 is a dangerous state, a danger preparatory state, or a possible danger state. Repeat periodically. On the other hand, if it is determined that none of the dangerous states exist, the control unit 101 advances to S1506 and determines whether or not a predetermined time has elapsed. The predetermined time indicates the elapsed time since it was last determined to be one of the dangerous states. Five minutes, for example, is set as the predetermined time. If the predetermined time has not passed, the process returns to S1503, and if it is determined that the predetermined time has passed, the process proceeds to S1507. ) and terminate the process. In addition, since there is a possibility that the other vehicle 200 cannot receive the signal with one transmission, it is desirable to continuously transmit the danger evacuation signal for a predetermined period of time.

Next, the processing of the other vehicle 200 will be explained. In S1511, the control unit 201 determines whether or not a retraction signal has been received after the start of imaging. Upon receiving the evacuation signal, the control unit 201 advances to S<b>1512 and acquires position information using the GPS 205 . Subsequently, in S1513, the control unit 201 attaches the acquired position information to the imaging data, transmits the imaging data to the external device 211, and ends the process. In this way, it may be determined whether or not the host vehicle 100 has escaped from a dangerous state, and if the host vehicle 100 has escaped, a signal indicating that fact may be transmitted to end the photographing of the other vehicle 200 .
