Abstract

An opening/closing body control device has a controller that controls a driving operation of a motor for carrying out an operation for opening/closing an opening/closing body of a vehicle, a load detector that detects a load of the motor; a deciding part that compares a variation in the load detected by the load detector with a predetermined threshold, thereby deciding presence of insertion of a foreign substance into the opening/closing body during the operation for closing the opening/closing body, an engine state detector that detects a stopping state of an engine of the vehicle, a receiver that receives a closing command for the opening/closing body which is transmitted from a remote control machine, and a changing part that changes the threshold.

Claims

1. An opening/closing body control device comprising:

a controller that controls a driving operation of a motor for carrying out an operation for opening/closing an opening/closing body of a vehicle;

a load detector that detects a load of the motor;

a deciding part that compares a variation in the load detected by the load detector with a predetermined threshold, thereby deciding presence of insertion of a foreign substance into the opening/closing body during the operation for closing the opening/closing body;

an engine state detector that detects a stopping state of an engine of the vehicle;

a receiver that receives a closing command for the opening/closing body which is transmitted from a remote control machine; and

a changing part that changes the threshold,

wherein, when the stopping state of the engine is detected by the engine state detector and the closing command is received by the receiver;

the changing part changes the threshold from a normal value to a sensitive value for detecting the insertion more sensitivity than the normal value,

the controller controls the motor to carry out the operation for closing the opening/closing body,

the controller controls the motor and stops the opening/closing body or carries out the opening operation after the stoppage if the deciding part decides that the insertion is present during the operation for closing the opening/closing body, and

the controller automatically controls the motor to carry out the operation for closing the opening/closing body if a predetermined time then passes.

2. The opening/closing body control device according to claim 1, wherein, while the controller automatically controls the motor to carry out the operation for closing the opening/closing body, the deciding part decides the presence of the insertion.

3. The opening/closing body control device according to claim 2, wherein, when the controller automatically controls the motor to carry out the operation for closing the opening/closing body, the changing part changes the threshold to a gentler value than the sensitive value.

4. The opening/closing body control device according to claim 2, wherein the controller automatically controls the motor to restrict, to a predetermined number of times, a number of times that the operation for closing the opening/closing body is carried out.

5. The opening/closing body control device according to claim 2, wherein, every time the controller automatically controls the motor to carry out the operation for closing the opening/closing body, the changing part changes the threshold to become stepwise gentler.

6. The opening/closing body control device according to claim 5, wherein the changing part changes the threshold from the sensitive value to the normal value so as to become stepwise gentler.

7. The opening/closing body control device according to claim 1, further comprising:

a door state detector that detects an opening/closing state of a door of a vehicle,

wherein, when the stopping state of the engine is detected by the engine state detector and the closing command for the opening/closing body is received by the receiver, and the closing states of all of the doors are detected by the door state detector;

the changing part changes the threshold from the normal value to the sensitive value, and

the controller controls the motor to carry out the operation for closing the opening/closing body.

8. The opening/closing body control device according to claim 1,

wherein the opening/closing body comprises a power window provided on the door and a window glass,

wherein an operating part is further provided in the vehicle, and

wherein the controller drives the motor to carry out an operation for opening/closing the window glass depending on a command sent from the remote control machine or an operation state of the operating part.

9. The opening/closing body control device according to claim 3, wherein the controller automatically controls the motor to restrict, to a predetermined number of times, a number of times that the operation for closing the opening/closing body is carried out.

10. The opening/closing body control device according to claim 3, wherein, every time the controller automatically controls the motor to carry out the operation for closing the opening/closing body, the changing part changes the threshold to become stepwise gentler.

11. The opening/closing body control device according to claim 4, wherein, every time the controller automatically controls the motor to carry out the operation for closing the opening/closing body, the changing part changes the threshold to become stepwise gentler.

12. The opening/closing body control device according to claim 9, wherein, every time the controller automatically controls the motor to carry out the operation for closing the opening/closing body, the changing part changes the threshold to become stepwise gentler.

13. The opening/closing body control device according to claim 2, further comprising:

a door state detector that detects an opening/closing state of a door of a vehicle,

wherein, when the stopping state of the engine is detected by the engine state detector and the closing command for the opening/closing body is received by the receiver, and the closing states of all of the doors are detected by the door state detector;
