Next, the operation of the vehicle-use home security system 10 will be described.
The user parks the vehicle 11 in the parking lot P of the home 12 and then connects the power line 14 connected to the home 12 to the PLC communication connector 28 of the vehicle-side communication control device 22. Then, power supply to the vehicle-mounted battery 27 is started from the home 12 side, and output signals from the sensors 18-1, 18-2, the GPS receiver 19, the camera 20, and the laser radar 21 are transmitted to the home 12.

  Specifically, after alternating current from the home power supply 33 of the home 12 is converted into direct current by the AC / DC converter 34, the vehicle is connected via the superposition / separation unit 37, the PLC communication connector 35, and the power line 14 of the home side communication control device 30. Power is supplied to the side communication control device 22. On the vehicle 11 side, the received power is supplied to the battery 27 via the PLC communication connector 28 and the superposition / separation unit 26 of the vehicle side communication control device 22.

  On the other hand, output signals from the sensors 18-1, 18-2, the GPS receiver 19, the camera 20, and the laser radar 21 are transmitted by the ECUs 17-1 to 5 to the vehicle-side communication control device 22 via the LAN. When the power line carrier communication is valid and the wireless communication is invalid, the output signal is superimposed on the power by the superposition / separation unit 26 via the gateway unit 23 and the PLC communication unit 24, and the power line 14 is connected from the PLC communication connector 28.

  The control signals of the various ECUs 17-1 to 17-5 and the like transmitted from the home security terminal 31 to the vehicle-side communication control device 22 side generate original data in a frame format that can be processed by the in-vehicle LAN on the home security terminal 31 side, The original data is encapsulated in the home LAN frame format and transmitted. That is, when it is transmitted from the home side communication control device 30 to the vehicle side communication control device 22, a format suitable for the in-vehicle LAN can be obtained simply by removing the capsule in the home LAN format. Therefore, the load on the system on the vehicle 11 side is reduced, and no extra cost is added to the vehicle 11.

In addition, when the power line 14 is disconnected or the wireless function is destroyed by a suspicious person and neither the power line carrier communication nor the wireless communication can be used, the sensors 18-1, 18-2, the GPS receiver 19, An output signal from the camera 20, the laser radar 21 or the like is transmitted from the communication device 16 and transmitted to the home security terminal 31 via the Internet N so that communication is possible even in an emergency.
The communication means between the vehicle 11 and the home 12 uses power line carrier (PLC) or wireless, but may be wired communication using a signal line.

  If it is set as the above structure, the sensors 18-1, 18-2, the camera 20, etc. which were previously mounted in the vehicle 11 parked in the home parking lot P will be utilized effectively, and the parked vehicle 11 and its surroundings will be displayed at home 12. Since the home security terminal 31 on the side can grasp it, the number of sensors and cameras newly installed in the home 12 can be reduced. That is, by using the vehicle 11 itself as a sensing medium, the home security system can be introduced at a low cost and the crime prevention performance can be improved. Further, mischief or theft of the vehicle 11 can be grasped while staying at home 12.

Further, since the vehicle-side communication control device 22 and the home-side communication control device 30 are connected by the power line 14 and the household power supply is supplied to the vehicle 11 so that the battery 27 can be charged, various sensors 18-1 can be used during parking. , 18-2, etc., are prevented from decreasing the amount of electricity stored in the battery 27. Furthermore, since the output signals from the various sensors 18-1, 18-2, etc. are transmitted to the home-side communication control device 30 using the power line carrier technology, the communication line becomes unnecessary and the wiring cost can be reduced. Wiring burden can be reduced.
Further, since the AC / DC converter 34 for converting the household power source 33 from alternating current to direct current is provided not at the vehicle 11 side but at the home 12 side, the vehicle 11 can be prevented from being increased in weight and size, and fuel consumption can be prevented from being lowered. it can.
The AC / DC converter 34 is provided not on the home 12 side but on the vehicle 11 side, and AC power is supplied to the power line 14, and AC is converted to DC on the vehicle side to supply power to the battery 27. Also good.
