Summary of the Invention

Problems to be Solved by the Invention

[0004] As a situation where a human approaches a vehicle, there may be a case where the user of the vehicle approaches the vehicle trying to drive, or there may be a case where a human simply passes by near the vehicle. Among such various situations, if the same process is performed regardless of the situation as in the security system of Patent Document 1, it is not necessarily highly convenient for the user of the vehicle.

Means for Solving the Problems

[0005] A security system for solving the above problems comprises a detector for detecting moving objects around a vehicle, a camera for photographing the area around the vehicle, a illuminator for illuminating the area around the vehicle, and a control device for controlling the detector, the camera, and the illuminator. A predetermined range including the location where the vehicle is parked is defined as the first range, and a predetermined range within the first range that is narrower than the first range is defined as the second range. The control device determines whether a first condition is met, including the requirement that the detector detected the moving object within the first range when the vehicle was parked; whether a second condition is met, including the requirement that the detector detected the moving object within the second range when the vehicle was parked; and changes one or more controls selected from the presence or absence of recording by the camera, the on / off processing of the illuminator, and the illuminance of the illuminator, depending on whether the first condition is met and the second condition is not met, or whether both the first and second conditions are met.

[0006] According to the above configuration, the control of one or more of the cameras and illuminators is changed in response to a change in the position of the moving object relative to the vehicle. This allows the cameras and illuminators to be controlled in a preferred manner according to the position of the moving object relative to the vehicle. [Brief explanation of the drawing]

[0007] [Figure 1] This is a schematic diagram of the security system. [Figure 2] This flowchart shows the pre-determination control. [Figure 3] This is a flowchart showing security control. [Figure 4] This is an explanatory diagram for describing the operation of the security system. [Modes for carrying out the invention]

[0008] <Outline configuration of the security system> An embodiment of the present invention will be described below with reference to Figures 1 to 4. First, the general configuration of the security system 100 will be described.

[0009] As shown in Figure 1, the security system 100 includes a vehicle 10. The vehicle 10 is, for example, a car owned by the user. The vehicle 10 is equipped with a motor generator 41 and a battery 42. The battery 42 supplies power to various devices, including the motor generator 41. The battery 42 is a so-called secondary battery. The motor generator 41 operates using power supplied from the battery 42. Therefore, the vehicle 10 is a so-called electric vehicle.

[0010] Vehicle 10 is equipped with a converter 43 and an inlet 45. The inlet 45 can be connected to an external power supply 90, which will be described later. The inlet 45 is electrically connected to the battery 42 via the converter 43. Power is supplied to the inlet 45 from the external power supply 90. The converter 43 converts the AC power supplied from the inlet 45 into DC power. The converter 43 supplies the converted DC power to the battery 42. As a result, the battery 42 is charged by the external power supply 90. In other words, the battery 42 can be charged by an external power supply 90 located outside the vehicle 10.

[0011] Vehicle 10 is equipped with a current sensor 31, a voltage sensor 32, a battery temperature sensor 33, and a GNSS receiver 34. The current sensor 31 detects the current IB that is input to and output from the battery 42. The voltage sensor 32 detects the voltage VB, which is the voltage across the terminals of the battery 42. The battery temperature sensor 33 detects the battery temperature TB, which is the temperature of the battery 42. The GNSS receiver 34 detects the position coordinates PC, which are the coordinates of the location where vehicle 10 is located, by communicating with a GNSS satellite (not shown). GNSS refers to the Global Navigation Satellite System.

[0012] The vehicle 10 is also equipped with an acceleration sensor 35, multiple cameras 36, a display 37, and an illuminator 51. The acceleration sensor 35 is a so-called three-axis sensor. That is, the acceleration sensor 35 can detect longitudinal acceleration GX, lateral acceleration GY, and vertical acceleration GZ. The longitudinal acceleration GX is the acceleration along the longitudinal axis of the vehicle 10. The lateral acceleration GY is the acceleration along the lateral axis of the vehicle 10. The vertical acceleration GZ is the acceleration along the vertical axis of the vehicle 10.

[0013] Each camera 36 captures a video PI of the area surrounding the vehicle 10. Each camera 36 captures a different area around the vehicle 10. The combined area of ​​the multiple cameras 36 covers almost the entire area around the vehicle 10, both front, back, left, and right. Each camera 36 also functions as a detector to detect moving objects around the vehicle 10. Each camera 36 operates based on power supplied from the battery 42. Note that Figure 1 shows only one of the multiple cameras 36.

[0014] The display 37 is capable of displaying various types of information. Furthermore, the display 37 is a so-called touch panel display. Therefore, users can input various types of information via the display 37.

[0015] The lighting unit 51 illuminates the area around the vehicle 10. The lighting unit 51 may be one or more of the headlights, taillights, hazard lights, or DRLs (Daytime Running Lamps) provided by the vehicle 10. The lighting unit 51 operates based on power supplied from the battery 42.

[0016] Vehicle 10 is equipped with a control device 20. The control device 20 acquires corresponding signals from a current sensor 31, a voltage sensor 32, a battery temperature sensor 33, and a GNSS receiver 34. The control device 20 also acquires corresponding signals from an acceleration sensor 35, a camera 36, ​​and a display 37. The control device 20 displays various information on the display 37 by outputting control signals to the display 37. The control device 20 also controls the illuminator 51 by outputting control signals to the illuminator 51. Furthermore, the control device 20 controls the capture of video PI by the camera 36 and the recording of the captured video PI by outputting control signals to the camera 36.

[0017] The control device 20 comprises an execution unit 21 and a storage unit 22. The storage unit 22 stores information acquired by the control device 20. The storage unit 22 also pre-stores various programs. Furthermore, the storage unit 22 can store setting information IS. Here, the setting information IS is either always on, area set, or non-on. Always on indicates that the security control described later will be executed without area restrictions. Area set indicates that the security control described later will be executed only in specific locations. Area set also includes information on the coordinates of the locations where security control should be executed. Non-on indicates that security control described later will not be executed regardless of the area. This setting information IS can be input by the user by operating the display 37. The execution unit 21 executes various processes by reading programs from the storage unit 22. An example of the execution unit 21 is a CPU.

[0018] The execution unit 21 calculates the charge level (SOC) of the battery 42 based on the current IB, voltage VB, and battery temperature TB at predetermined control cycles. The charge level (SOC) is expressed by the following formula (1).

[0019] Equation (1): State of Charge (SOC) [%] = Remaining capacity of battery 42 [Ah] / Fully charged capacity of battery 42 [Ah] × 100 [%] Among the above formula (1), the full charge capacity is the maximum amount of electric power that the battery 42 can store. The full charge capacity varies slightly depending on the voltage VB and current IB history of the battery 42, and the battery temperature TB. Therefore, the full charge capacity is calculated based on the voltage VB and current IB history of the battery 42, and the battery temperature TB. Also, the remaining capacity is calculated based on, for example, the integrated value of the current IB after the battery 42 is fully charged, and the voltage VB.

[0020] Also, the execution unit 21 executes monitoring control each time a predetermined condition is satisfied. Here, the execution unit 21 determines that the predetermined condition is satisfied when, for example, all of the following requirements (1) and (2) are satisfied.

[0021] Requirement (1): The vehicle 10 is parked. Requirement (2): One or more of the longitudinal acceleration GX, lateral acceleration GY, and vertical acceleration GZ are greater than or equal to a predetermined defined acceleration.

[0022] Therefore, for example, when a certain impact is applied to the vehicle 10 while the vehicle 10 is parked, the execution unit 21 determines that the predetermined condition is satisfied. And in the monitoring control, the execution unit 21, for example, activates the camera 36 to capture the video PI with the camera 36, and stores the captured video PI in the storage unit 22. In other words, the execution unit 21 executes recording with the camera 36. Note that the execution unit 21 ends the monitoring control when a predetermined fixed period has elapsed since the predetermined condition was satisfied.

[0023] As shown in FIG. 1, the security system 100 includes an external power source 90. The external power source 90 includes a power supply main body 91, a circuit breaker 92, and a connector 95. The connector 95 can be connected to the inlet 45 of the vehicle 10. The connector 95 is connected to the power supply main body 91 via the circuit breaker 92. The circuit breaker 92 can cut off the electrical connection between the connector 95 and the power supply main body 91. The power supply main body 91 can supply AC power.

[0024] <Pre-determination control> Next, with reference to Figure 2, the pre-determination control performed by the control device 20 will be described. The control device 20 repeatedly performs pre-determination control when predetermined pre-determination conditions are met. The pre-determination conditions are, for example, that the vehicle 10 is parked. In this pre-determination control, the control device 20 sets the execution flag F to on or off for executing the anti-theft control described later. In this embodiment, the control device 20 sets the execution flag F to off when the pre-determination conditions are met. That is, when the first pre-determination control is started, the execution flag F is off.

[0025] As shown in Figure 2, when the control device 20 starts pre-determination control, it executes the process in step S11. In step S11, the control device 20 determines whether the charge rate (SOC) is equal to or greater than a predetermined specified charge rate (SA). Here, the specified charge rate (SA) is a threshold for determining whether the battery 42 has a sufficient charge rate (SOC) to perform the security control described later. An example of a specified charge rate (SA) is several tens of percent. If the control device 20 determines in step S11 that the charge rate (SOC) is equal to or greater than the specified charge rate (SA) (S11: YES), the control device 20 proceeds to step S21. On the other hand, if the control device 20 determines in step S11 that the charge rate (SOC) is less than the specified charge rate (SA) (S11: NO), the control device 20 proceeds to step S12.

[0026] In step S12, the control device 20 determines whether the battery 42 is being charged by the external power supply 90 at the time of processing in step S12. If the control device 20 determines in step S12 that the battery 42 is being charged by the external power supply 90 (S12: YES), the control device 20 proceeds to step S21.

[0027] In step S21, the control device 20 determines whether continuous operation of the security control, described later, is desired, based on whether the setting information IS is set to continuous operation. If the control device 20 determines in step S21 that continuous operation of the security control is desired (S21:YES), the control device 20 proceeds to step S31. On the other hand, if the control device 20 determines in step S21 that continuous operation of the security control is not desired (S21:NO), the control device 20 proceeds to step S22.

[0028] In step S22, the control device 20 determines whether an area is set for which the security control described later is to be operated, based on whether the setting information IS is set to an area setting. If the control device 20 determines in step S22 that an area is set for which the security control is to be operated (S22:YES), the control device 20 proceeds to step S23.

[0029] In step S23, the control device 20 determines whether the coordinates of the location where security control should be performed and the location coordinates PC of the vehicle 10 match, based on the coordinates of the location where security control should be performed and the location coordinates PC included in the setting information IS. The control device 20 determines that the two coordinates match if the difference between the coordinates of the location where security control should be performed and the location coordinates PC of the vehicle 10 is within a predetermined error range. For example, the user can set the coordinates of their home parking lot as the coordinates of the location where security control should be performed. If the control device 20 determines in step S23 that the coordinates of the location where security control should be performed and the location coordinates PC of the vehicle 10 match (S23:YES), the control device 20 proceeds to step S31.

[0030] In step S31, the control device 20 sets the execution flag F to ON. After step S31, the control device 20 terminates the current pre-determination control. Then, the control device 20 proceeds to step S11 again.

[0031] On the other hand, if the control device 20 determines in step S12 above that the battery 42 is not being charged by the external power supply 90 (S12: NO), the control device 20 proceeds to step S32. Also, if the control device 20 determines in step S22 above that no area is set for which security control is to be performed (S22: NO), the control device 20 proceeds to step S32. In other words, if the control device 20 determines that the setting information IS is inactive, the control device 20 proceeds to step S32. Furthermore, if the control device 20 determines in step S23 above that the coordinates of the location where security control should be performed do not match the position coordinates PC of the vehicle 10 (S23: NO), the control device 20 proceeds to step S32.

[0032] In step S32, the control device 20 sets the execution flag F to off. After step S32, the control device 20 terminates the current pre-determination control. Then, the control device 20 proceeds to step S11 again.

[0033] <Security control> Next, with reference to Figure 3, the anti-theft control performed by the control device 20 will be described. The control device 20 repeatedly performs anti-theft control on the condition that the execution flag F is on. The pre-determination control described above is performed on the condition that the vehicle 10 is parked. When this pre-determination control is performed, the execution flag F is set to on. Therefore, the anti-theft control is performed when the vehicle 10 is parked.

[0034] As shown in Figure 3, when the control device 20 starts security control, it executes the process in step S51. In step S51, the control device 20 determines whether or not a moving object has been detected by the camera 36 within a predetermined first range A1. Here, the first range A1 is a predetermined range that includes the location where the vehicle 10 is parked. For example, as shown by the dashed line in Figure 4, the first range A1 is the range that includes the vehicle 10 and can be photographed by any of the cameras 36. The first range A1 is predetermined as, for example, a rectangular area with sides of several meters. As shown in Figure 3, if the control device 20 determines in step S51 that no moving object has been detected by the camera 36 within the first range A1 (S51: NO), the control device 20 proceeds to step S73.

[0035] As shown in Figure 3, in step S73, the control device 20 controls the illuminator 51 to turn off. As a result, the illuminator 51 does not illuminate the area around the vehicle 10. If the illuminator 51 is already off at step S73, the control device 20 continues to keep the illuminator 51 off. The control device 20 also stops recording on each camera 36. Similarly, if recording on each camera 36 is already stopped at step S73, the control device 20 continues to keep recording stopped on each camera 36. After step S73, the control device 20 terminates the current security control. The control device 20 then proceeds to step S51.

[0036] On the other hand, if the control device 20 determines in step S51 above that a moving object has been detected by the camera 36 within the first range A1 (S51: YES), the control device 20 proceeds to step S61. In this embodiment, the requirement that a positive determination was made in step S51 is the first condition.

[0037] In step S61, the control device 20 determines whether a moving object has been detected by the camera 36 within a predetermined second range A2. Here, the second range A2 is a predetermined range within the first range A1 that is narrower than the first range A1. For example, as shown by the dashed line in Figure 4, the second range A2 is a rectangular area that includes the vehicle 10 and is smaller than the first range A1. The second range A2 is predetermined as, for example, a rectangular area with sides of several meters. In this embodiment, each side of the second range A2 is located closer to the vehicle 10 than each side of the first range A1. As shown in Figure 3, if the control device 20 determines in step S61 that a moving object has been detected by the camera 36 within the second range A2 (S61: YES), the control device 20 proceeds to step S62. In this embodiment, the requirement that a positive determination was made in step S61 is the second condition.

[0038] In step S62, the control device 20 performs recording with the camera 36. In other words, the execution unit 21 of the control device 20 stores the video PI captured by the camera 36 in the storage unit 22. After step S62, the control device 20 proceeds to step S63.

[0039] In step S63, the control device 20 determines whether the moving object is stationary within a predetermined second range A2. Specifically, the control device 20 defines the continuous period TX as the period during which the camera 36 continuously detects the moving object within the second range A2, up to the processing time of step S63, which is the period during which the camera 36 continuously detects the moving object. The control device 20 also determines whether the continuous period TX is equal to or greater than a predetermined specified period TA. The control device 20 then determines that the moving object is stationary within the second range A2 if the continuous period TX is equal to or greater than the specified period TA. An example of a specified period TA is several tens of seconds to several minutes. The control device 20 resets the continuous period TX each time it makes a negative determination in step S61. If the control device 20 determines in step S63 that the moving object is stationary within the second range A2 (S63: YES), the control device 20 proceeds to step S64.

[0040] In step S64, the control device 20 determines whether the moving object is a person other than a predetermined specific person based on the video PI captured by the camera 36. Specifically, the control device 20 extracts a human face from the image captured by the camera 36. Then, the control device 20 compares the extracted facial feature points with predetermined feature points using a known method. If the comparison results are equal to or greater than a predetermined agreement rate, the control device 20 determines that the moving object is a predetermined specific person. On the other hand, if the comparison results are less than a predetermined agreement rate, the control device 20 determines that the moving object is a person other than a predetermined specific person. The predetermined specific person is, for example, the user of the vehicle 10. If the control device 20 determines in step S64 that the moving object is a person other than a predetermined specific person (S64:YES), the control device 20 proceeds to step S71. That is, the control device 20 proceeds to step S71 only if both requirements are met: the requirement that an affirmative determination was made in step S63, and the requirement that an affirmative determination was made in step S64. In this embodiment, the third condition is that two requirements are met: that a positive determination is made in step S63, and that a positive determination is made in step S64.

[0041] In step S71, the control device 20 performs a warning illumination by controlling the illuminator 51 to turn on. Specifically, in warning illumination, the control device 20 controls the on / off state of the illuminator 51 to intermittently illuminate the area around the vehicle 10 with light. In other words, the illuminator 51 flashes. After step S71, the control device 20 terminates the current security control. Then, the control device 20 proceeds to step S51 again.

[0042] On the other hand, if the control device 20 determines in step S61 above that no moving object has been detected by the camera 36 within the second range A2 (S61: NO), the control device 20 proceeds to step S72. The control device 20 stops recording with each camera 36 when it makes a negative determination in step S61. Also, if the control device 20 determines in step S63 above that no moving object is stationary within the second range A2 (S63: NO), the control device 20 proceeds to step S72. Furthermore, if the control device 20 determines in step S64 above that the moving object is a predetermined specific person (S64: NO), the control device 20 proceeds to step S72.

[0043] In step S72, the control device 20 performs support illumination by controlling the illuminator 51 to turn on. Specifically, in support illumination, the control device 20 controls the illuminator 51 to turn on and continuously illuminates the area around the vehicle 10 with light. In other words, the illuminator 51 turns on. At this time, the control device 20 lowers the illuminance of the illuminator 51 to a level lower than the illuminance when the illuminator 51 was turned on in the warning illumination in step S71. After step S72, the control device 20 terminates this security control. Then, the control device 20 proceeds to step S51 again.

[0044] <Operation of this embodiment> As shown by the solid arrows in Figure 4, assume that a person is approaching the vehicle 10. When the person approaches within the first range A1, the first condition is met. At this time, as shown in Figure 3, in step S72, the control device 20 performs support illumination. That is, the control device 20 controls the illuminator 51 to turn on, continuously illuminating the area around the vehicle 10. As a result, for example at night, the area around the vehicle 10 is illuminated, making it easier for users and others to recognize the area around the vehicle 10.

[0045] On the other hand, the second condition is met when a person approaches within the second range A2. At this time, as shown in Figure 3, in step S62, the control device 20 performs recording with the camera 36. Furthermore, provided that the second condition is met, if a person other than the user is stationary within the second range A2, the control device 20 performs warning illumination. That is, the control device 20 controls the on / off state of the illuminator 51 to intermittently illuminate the area around the vehicle 10.

[0046] Thus, the control device 20 changes the processing related to whether or not recording is performed by the camera 36, ​​the on / off switching of the illuminator 51, and the control of the illuminance of the illuminator 51 depending on whether the first condition is met but the second condition is not met, or whether both the first and second conditions are met.

[0047] <Effects of this embodiment> (1) As described above, when the first condition is met but the second condition is not met, recording is not performed by the camera 36, ​​whereas when both the first and second conditions are met, recording is performed by the camera 36. Therefore, for example, when a person approaches the vehicle 10, and security precautions are needed for the vehicle 10, recording can be performed by the camera 36.

[0048] Furthermore, the on / off control of the illuminator 51 and the illuminance control of the illuminator 51 change depending on whether the first condition is met but the second condition is not, or whether both the first and second conditions are met. In this way, the control of the camera 36 and the illuminator 51 is changed in accordance with the change in the position of the moving body relative to the vehicle 10. Therefore, in this embodiment, the camera 36 and the illuminator 51 can be controlled in a preferred manner according to the position of the moving body relative to the vehicle 10.

[0049] (2) In the pre-determination control, the control device 20 sets the execution flag F to ON, on the condition that the battery 42 is being charged by the external power supply 90. Then, the control device 20 executes the security control on the condition that the execution flag F is ON. In other words, on the condition that the battery 42 is being charged by the external power supply 90, a determination is made as to whether the first and second conditions in the security control have been met. If the determination of whether the first and second conditions have been met is not made, the subsequent recording by the camera 36, ​​and the turning on and flashing of the lighting fixture 51 will not occur. Therefore, the consumption of power from the battery 42 can be suppressed as a result of the determination of whether the first and second conditions in the security control have been met is made.

[0050] (3) In terms of security for the vehicle 10, for example, the longer a person remains within the second range A2, the higher the likelihood of harm to the vehicle 10. In this regard, the control device 20 executes the process of step S71 when the third condition, which includes the requirement confirmed in step S63, namely that the continuous period TX is equal to or greater than the predetermined specified period TA, is met. Then, in step S71, the control device 20 controls the on / off switching of the illuminator 51 to intermittently illuminate the area around the vehicle 10. As a result, in terms of security for the vehicle 10, the illuminator 51 flashes in situations where greater caution is needed, thereby drawing attention to the area around the vehicle 10.

[0051] (4) For example, even if a person remains within the second range A2 for a long period of time, if that person is a user of the vehicle 10, there is no need to draw attention to the area around the vehicle 10. In this regard, in this embodiment, the third condition includes the requirement that was affirmed in step S64, namely the requirement that the moving object is a person other than a predetermined specific person. Therefore, even if a person remains within the second range A2 for a long period of time, if that person is a user of the vehicle 10, the control device 20 does not execute the process in step S71, but executes the process in step S72. This prevents the user of the vehicle 10 from feeling uncomfortable due to the flashing of the illuminator 51 when the user of the vehicle 10 is located within the second range A2.

[0052] (5) In this embodiment, if the configuration information IS is inactive, the execution flag F is turned off. On the other hand, if the configuration information IS is always active or set to area mode, the execution flag F may be turned on. In this way, the user can choose whether or not to execute the security control, so it is possible to set it up according to the user's preference.

[0053] (6) In this embodiment, when the setting information IS is set to area setting, the execution flag F can be turned on only when the coordinates of the location where the predetermined security control should be performed match the position coordinates PC of the vehicle 10. Therefore, detailed settings are possible regarding whether or not the security control is performed, according to the parking position of the vehicle 10.

[0054] <Example of changes> This embodiment can be implemented with the following modifications. This embodiment and the following modifications can be combined with each other to the extent that they do not contradict each other technically.

[0055] • In the above embodiment, the pre-determination control may be modified. For example, the process in step S11 may be omitted. In this case, the control device 20 only needs to execute the process in step S12 when it starts the pre-determination control.

[0056] For example, the process in step S12 may be omitted. In this case, if the control device 20 determines that the result is negative in step S11, it should proceed to step S32. For example, the process in step S23 may be changed. Specifically, the area setting in the setting information IS may include information on the coordinates of a location where security control is not performed. In this case, in step S23, the control device 20 may determine whether the coordinates of the location where security control is not performed match the location coordinates PC of the vehicle 10. In this case, in step S23, if the coordinates of the location where security control is not performed match the location coordinates PC of the vehicle 10, the control device 20 should proceed to step S32.

[0057] For example, steps S22 and S23 may be omitted. In this case, if the control device 20 determines that step S21 is negative, it should proceed to step S32.

[0058] For example, steps S21 to S23 may be omitted. In this case, the control device 20 may proceed to step S31 if it makes a positive determination in step S11 or step S12.

[0059] • In the above embodiment, the security control may be modified. For example, the process in step S62 may be modified. Specifically, in step S62, the control device 20 may increase the illuminance of the illuminator 51 in addition to, or instead of, performing recording with the camera 36. In other words, the control device 20 may increase the illuminance of the illuminator 51 when both the first and second conditions are met, compared to when the first condition is met but the second condition is not. This increases the illumination around the vehicle 10 in situations where security precautions for the vehicle 10 are necessary.

[0060] For example, the order of processing in steps S62 and S63 may be changed. Specifically, if the control device 20 determines that step S61 is positive, it proceeds to step S63. Then, if the control device 20 determines that step S63 is positive, it executes the processing in step S62. In this case, the second condition includes the requirement that a positive determination was made in step S61 and the requirement that a positive determination was made in step S63.

[0061] For example, the order of processing in steps S62, S63, and S64 may be changed. Specifically, if the control device 20 determines that step S61 is positive, it proceeds to step S63. If the control device 20 determines that step S63 is positive, it proceeds to step S64. If the control device 20 determines that step S64 is positive, it executes the processing in step S62. In this case, the second condition includes the requirements that a positive determination was made in step S61, in step S63, and in step S64.

[0062] For example, the process in step S64 may be omitted. In this case, the third condition is the requirement that the result in step S63 was positive. For example, the process in step S71 may be changed. Specifically, in step S71, the control device 20 may turn on the illuminator 51 instead of flashing it. Alternatively, for example, the control device 20 may set the illuminance when the illuminator 51 is turned on to be the same as the process in step S72.

[0063] In the above embodiment, monitoring and control may be omitted. • In the above embodiment, the configuration of the security system 100 may be changed. For example, the security system 100 may be equipped with a millimeter-wave radar, LiDAR, or the like as a detector. In this case, the camera 36 does not need to function as a detector.

[0064] For example, the security system 100 may include components other than the vehicle 10 and the external power supply 90. Specifically, the security system 100 may include a lighting fixture 51 installed in the user's home or elsewhere. In this case, in steps S71, S72, and S73, the control device 20 may control the lighting fixture 51 installed in the user's home or elsewhere, in addition to or instead of the lighting fixture 51 provided in the vehicle 10. The control device 20 can control the lighting fixture 51 installed in the user's home or elsewhere by communicating with external equipment of the vehicle 10 using a communication device (not shown). Also, as a specific example, the security system 100 may include a separate control device outside the vehicle 10 that performs pre-determination control and security control. In this case, the control device 20 can transmit various information to the control device that performs pre-determination control and security control by communicating with external equipment of the vehicle 10 using a communication device (not shown).
