OPENING AND CLOSING CONTROL DEVICE
An opening and closing control device includes a motor configured to drive, in an opening and closing direction, an opening and closing body that is supported a vehicle body and allowed to be opened and closed, a controller configured to control the motor, and a pulse encoder configured to output a pulse signal. The controller adjusts an advance angle of the motor, detects a rotational speed of the motor or an opening and closing speed of the opening and closing body according to pulse detection based on the pulse signal output from the pulse encoder, and detects a pinching state of the opening and closing body when the rotational speed of the motor or the opening and closing speed of the opening and closing body is equal to or less than a threshold value during advance angle control on the motor.
1 . An opening and closing control device, comprising:
a motor configured to drive, in an opening and closing direction, an opening and closing body that is supported a vehicle body and allowed to be opened and closed;
a controller configured to control the motor; and
a pulse encoder configured to output a pulse signal,
wherein the controller is configured to:
adjust an advance angle of the motor;
detect a rotational speed of the motor or an opening and closing speed of the opening and closing body according to pulse detection based on the pulse signal output from the pulse encoder; and
detect a pinching state of the opening and closing body when the rotational speed of the motor or the opening and closing speed of the opening and closing body is equal to or less than a threshold value during advance angle control on the motor.
2 . The opening and closing control device according to claim 1 ,
wherein the controller detects the pinching state of the opening and closing body when the rotational speed of the motor or the opening and closing speed of the opening and closing body is equal to or less than the threshold value during normal control on the motor in which the advance angle control is not performed.
3 . The opening and closing control device according to claim 1 , further comprising:
an inclination detector configured to detect an inclination angle of the vehicle body,
wherein the controller changes the advance angle based on the inclination angle.
4 . The opening and closing control device according to claim 3 ,
wherein in a case where an operation direction is inclined upward in an opening and closing operation of the opening and closing body, the controller performs the advance angle control when the inclination angle is equal to or less than a set value.
5 . The opening and closing control device according to claim 3 ,
wherein in a case where an operation direction is inclined upward in an opening and closing operation of the opening and closing body, the controller reduces the advance angle as the inclination angle increases.
6 . The opening and closing control device according to claim 3 ,
wherein in a case where an operation direction is inclined upward in an opening and closing operation of the opening and closing body, the controller performs normal control on the motor in which the advance angle control is not performed when the inclination angle is larger than a set value.
7 . The opening and closing control device according to claim 1 ,
wherein in an opening and closing operation region where a load on the opening and closing body is prone to vary, the controller performs the advance angle control with reducing the advance angle or performs normal control on the motor in which the advance angle control is not performed, as compared with an opening and closing operation region where the load on the opening and closing body is hard to vary.
8 . The opening and closing control device according to claim 7 ,
wherein the opening and closing body is a slide door, and
the opening and closing operation region where the load on the opening and closing body is prone to vary includes a deceleration region before the opening and closing body reaches a half door position and a latch engaging region before the opening and closing body reaches a full-open position.
