Abstract

An operation detecting device of an opening and closing body for a vehicle, includes: a detecting section that detects an operation by a user with respect to an opening and closing body of a vehicle; an input section that receives an opening and closing body motion signal which indicates whether or not the opening and closing body is in motion or idle; a determination section that determines whether or not the operation is performed using different detection conditions for a case in which the opening and closing body is in motion and a case in which the opening and closing body is idle; and an output section that outputs a control signal which causes the opening and closing body to move or stop based on the determination result of the determination section.

Claims

1. An operation detecting device of an opening and closing body for a vehicle, comprising:

a detecting section that detects an operation by a user with respect to an opening and closing body of a vehicle, the detecting section includes a plurality of electrodes which detect a change of an electrostatic capacitance value which is generated due to the operation;

an input section that receives an opening and closing body motion signal which indicates whether or not the opening and closing body is in motion or idle;

a determination section that determines whether or not the operation is performed using different detection conditions for a case in which the opening and closing body is in motion and a case in which the opening and closing body is idle; and

an output section that outputs a control signal which causes the opening and closing body to move or stop based on the determination result of the determination section;

wherein,

the determination section determines whether or not the operation is performed, based on the change of the electrostatic capacitance value,

when the opening and closing body is idle, the determination section determines that the operation is performed in a case in which a plurality of the electrostatic capacitance values detected by the plurality of electrodes shows a variation pattern corresponding to a predetermined gesture of the user, and

when the opening and closing body is in motion, the determination section determines that the operation is performed in a case where it is detected that at least one of the plurality of electrostatic capacitance values detected by the plurality of electrodes is changed to a predetermined threshold or more due to the operation.

2. The operation detecting device of an opening and closing body for a vehicle according to claim 1

wherein, when the opening and closing body is in motion, the detecting section determines whether or not the operation is performed based on the electrostatic capacitance values detected by a larger number of electrodes than when the opening and closing body is idle.

3. The operation detecting device of an opening and closing body for a vehicle according to claim 1,

wherein, when the detecting section determines that the operation is performed while the opening and closing body is in motion, the output section outputs the control signal which causes the opening and closing body to be idle.

4. An operation detecting device of an opening and closing body for a vehicle, comprising:

a detecting section that detects an operation by a user with respect to an opening and closing body of a vehicle, the detecting section includes a plurality of electrodes which detect a change of an electrostatic capacitance value which is generated due to the operation;

an input section that receives an opening and closing body motion signal which indicates whether or not the opening and closing body is in motion or idle;

a determination section that determines whether or not the operation is performed using different detection conditions for a case in which the opening and closing body is in motion and a case in which the opening and closing body is idle; and

an output section that outputs a control signal which causes the opening and closing body to move or stop based on the determination result of the determination section;

wherein,

the determination section determines whether or not the operation is performed, based on the change of the electrostatic capacitance value,

when the opening and closing body is idle, the detecting section determines that the operation is performed in a case where it is detected that a state in which the electrostatic capacitance value is changed to a predetermined threshold or more due to the operation continues for a first time or more, and

when the opening and closing body is in motion, the detecting section determines that the operation is performed in a case where it is detected that a state in which the electrostatic capacitance value is changed to a predetermined threshold or more due to the operation continues for a second time or more which is shorter than the first time.
