Abstract
A control device controls opening/closing of a sliding door of a vehicle by a motor in cooperation with a drive device that opens and closes the sliding door, and applies proportional plus integral plus differential control to motor speed based on a driving pattern of the sliding door. When a difference between a door speed and a motor speed exceeds a threshold, the control device judges that the vehicle is parked in a tilted state, and adjusts a sum of a proportional element, an integral element, and a differential element of a proportional plus integral plus differential control to a vehicle-tilted time element.
Claims9
A control device for controlling opening/closing of a sliding door of a vehicle by a motor in cooperation with a drive device that opens and closes the sliding door, comprising:
- a detecting unit that detects door speed of the sliding door;
- an applying unit that applies, based on a driving pattern of the sliding door set in advance, proportional plus integral plus differential control to motor speed of the motor;
- a tilt-judging unit that judges, when a difference between the door speed and the motor speed exceeds a threshold within a predetermined time from when the sliding door starts to open/close, that the vehicle is parked in a tilted state;
- and
- an adjusting unit that adjusts a sum of a proportional element, an integral element, and a differential element of the proportional plus integral plus differential control to a vehicle-tilted time element.
A control device for controlling opening/closing of a sliding door of a vehicle by a motor in cooperation with a drive device that opens and closes the sliding door, comprising:
- a detecting unit that detects door speed of the sliding door;
- an applying unit that applies, based on a driving pattern of the sliding door set in advance, feedback control to motor speed of the motor;
- a tilt-judging unit that judges, when a difference between the door speed and the motor speed exceeds a threshold within a predetermined time from when the sliding door starts to close, that the vehicle is parked in a tilted state;
- and
- an adjusting unit that brings forward a deceleration start timing of the driving pattern.

- a detecting unit that detects door speed of the sliding door;
- an applying unit that applies, based on a driving pattern of the sliding door set in advance, feedback control to motor speed of the motor;
- a tilt-judging unit that judges, when the sliding door closes from a half-opened state, that the vehicle is parked in a tilted state, regardless of whether the vehicle is actually tilted;
- and
- an adjusting unit that brings forward a deceleration start timing of the driving pattern.

A control device for controlling opening/closing of a door of a vehicle by a motor in cooperation with a drive device that opens and closes the door, comprising:
- a detecting unit that detects door speed of the door;
- an applying unit that applies, based on a driving pattern of the door set in advance, feedback control to motor speed of the motor;
- a follow-up judging unit that judges, when a difference between the door speed and the motor speed exceeds a threshold after elapse of a predetermined time from when the door starts to open/close, that the door is subjected to a follow-up operation.
