Specifically, the current position detection unit 200 emits infrared rays, millimeter wave radar, ultrasonic waves, etc., and uses the reflected light to measure the distance to a human body or an object to detect the proximity state. is there. For example, a millimeter wave radar detects a user's current position in a predetermined range by using a millimeter wave band radio wave. Since this method uses radio waves, it can be used even in fog or during rain or snow. Currently, the available frequency bands are the 60 GHz band and the 76 GHz band, and the technical conditions are defined as a low power millimeter wave radar.

Note that the opening/closing angle control unit 500 may control the opening/closing angle each time the blocking presence/absence state received from the operation intention detection unit 400 changes from a state in which light is not blocked to a state in which light is blocked. , After the lapse of a predetermined time or within a predetermined time interval, if the state of presence or absence of interruption does not change from the state where light is not blocked to the state where light is blocked The opening/closing angle of the opening/closing body may be controlled.

The opening/closing angle control unit 500 can also control the opening/closing angle of the vehicle opening/closing body only during a predetermined angle of the vehicle opening/closing body during opening/closing.

For example, in the case of the opening operation, the opening/closing angle control unit 500 moves the vehicle opening/closing body to a predetermined angle (for example, 45 degrees) in the opening operation in response to the operation intention detecting unit 400 detecting the operation intention of the user. To automatically open and control the opening/closing angle of the vehicle opening/closing body in accordance with the interruption presence/absence state detected by the operation intention detecting unit 400 between the predetermined angle and the angle at which the vehicle opening/closing body is completely opened. Can also

On the contrary, in the case of the closing operation, the opening/closing angle control unit 500 operates between the angle when the vehicle opening/closing body is completely opened and the predetermined angle in response to the operation intention detecting unit 400 detecting the operation intention of the user. In the above, the opening/closing angle of the vehicle opening/closing body is controlled according to the interruption presence/absence state detected by the operation intention detecting unit 400, and when the vehicle opening/closing body is closed from a predetermined angle, it is automatically closed to the completely closed state.

For example, the collision detection unit 600 detects that there is a possibility of collision with the vehicle opening/closing body when the distance between the vehicle opening/closing body and the obstacle becomes equal to or less than a preset predetermined value.

The vehicle opening/closing body control unit 700 controls the opening/closing operation of the vehicle opening/closing body when the operation intention detecting unit 400 detects the operation intention of the user. The vehicle opening/closing body includes at least a back door and a side door (rear door).

The vehicle opening/closing body drive unit 800 drives the vehicle opening/closing body. Specifically, the vehicle opening/closing body drive unit 800 opens the vehicle opening/closing body according to the angle determined by the opening/closing angle control unit 500 when an operation of blocking the formed display for detecting the operation intention is performed. To drive. Further, the vehicle opening/closing body drive unit 800 stops driving the vehicle opening/closing body when the collision detection unit 600 detects that the vehicle opening/closing body may collide.

The device control unit 900 receives signals from each unit and controls the overall operation of the vehicle opening/closing body control device according to a control program stored in a ROM (Read Only Memory).
