[0022]
The smart ECU 101 has a transmission / reception circuit. The smart ECU 101 collates an ID transmitted from a key having a transmission / reception function with an ID stored in the smart ECU 101 in advance. Lock and unlock each door. Further, the smart ECU 101 detects lock / unlock of each door by this transmission / reception. The body ECU 102 detects that each door of the vehicle 10 has been locked / unlocked by manual operation. The smart ECU 101 and the body ECU 102 both output a door lock / unlock signal to the mobile security ECU 20.
[0023]
When the key is inserted into a key cylinder (not shown) provided in the passenger compartment, the immobilizer ECU 103 receives the ID transmitted from this key, and the received ID and the ID stored on the vehicle 10 side. It is judged whether or not. If it is determined by this determination that the regular key is being used, the immobilizer ECU 103 instructs the engine ECU (not shown) to start the engine, or releases the lock of the key cylinder. Or
[0024]
Further, the immobilizer ECU 103 outputs a signal corresponding to whether the key determination is correct to the mobile security ECU 20. In the immobilizer ECU 103, for example, it may be determined whether or not an accessory is turned on with a regular key, or whether or not an ignition is turned on with a regular key.
[0025]
When all the doors of the vehicle 10 are locked, the mobile security ECU 20 inputs a door lock signal and sets the mode from the security unset mode to the security set mode for detecting the approach of a person to the vehicle from the security unset mode.

The approach sensor 108 includes, for example, a transmission / reception circuit that transmits and receives radio waves such as microwaves and a microcomputer (both not shown). As shown in FIG. Installed in the center.
[0028]
That is, the transmission circuit radiates radio waves around the vehicle 10 for a very short time (radiation pulse), and the reception circuit receives a reflected wave (reflection pulse) from an object with respect to the radiation pulse. Then, the distance to the object is calculated based on the time from when the radiation pulse is emitted until the reflected pulse is received. When the distance to the object is located within a preset area A shown in FIG. 8, the approach sensor 108 recognizes the approach of the object to the vehicle 10.
[0029]
On the other hand, whether or not the object located in the area A is a person is determined from the reflection area (scattering cross section). That is, the power of the radiation pulse radiated from the transmission circuit is attenuated by being absorbed by the object, and the power that cannot be absorbed by the object is received by the reception circuit as the power of the reflected pulse. Since the amount of power attenuation is proportional to the reflection area, the reflection area is calculated by the ratio of the power of the radiation pulse and the power of the reflection pulse. When the reflection area is about the reflection area by a person, it is determined that the object located in the area A is a person. Thereby, the approach of the person to the vehicle 10 can be detected. Note that the degree of the reflection area of a person is obtained in advance by experiments or the like.
