Abstract

A door opening/closing control device includes: a driving part driving an actuator opening or closing a door; an operation switch operated for instructing opening/closing or stopping of the door; a first controller controlling driving of the actuator via the driving part in accordance with the operation; a manual opening/closing detector detecting that the door is manually opened or closed; and a second controller controlling the driving of the actuator via the driving part to assist a manual operation of opening or closing the door when the manual opening/closing detector detects the manual opening/closing operation. Then, when the second controller controls the driving of the actuator to assist the manual operation of opening or closing the door, even when the operation switch is operated, the first controller does not control the driving of the actuator in accordance with the operation, and the second controller continues to control the driving.

First claim

The invention claimed is:

1. A door opening and closing control device, comprising:
a driving part configured to drive an actuator that opens or closes a door;
an operation switch configured to accept an operation for opening, closing, or stopping movement of the door, and to send an instruction indicating the operation;
a first controller configured to control driving of the actuator via the driving part in accordance with the instruction indicating the operation of the operation switch;
a manual opening or closing detector configured to detect that the door is manually opened or closed; and
a second controller configured to control the driving of the actuator via the driving part so as to assist a manual operation of opening or closing the door when the manual opening or closing detector detects the manual opening or closing operation,
wherein, while the second controller is controlling the driving of the actuator so as to assist the manual operation of opening or closing the door, operation of the operation switch is ignored or invalidated, such that the first controller does not control the driving of the actuator in accordance with the instruction indicating the operation, and the second controller continues to control the driving of the actuator.

2. The door opening and dosing control device according to claim 1 , further comprising:
a position detector configured to detect an opening or closing position of the door;
a speed calculator configured to calculate an opening or closing speed of the door based on a temporal change in the opening or closing position detected by the position detector; and
a target speed calculator configured to calculate a target speed based on the opening or closing position detected by the position detector,
wherein the first controller controls the driving of the actuator based on the opening dosing speed calculated by the speed calculator and the target speed calculated by the target speed calculator.

3. The door opening and closing control device according to claim 2 , further comprising:
a target assisting force calculator configured to calculate target assisting force based on the opening or closing position detected by the position detector and the opening or closing speed calculated by the speed calculator; and
a current detector configured to detect a driving current of the actuator,
wherein the second controller controls the driving of the actuator based on the target assisting force calculated by the target assisting force calculator and the driving current detected by the current detector.

4. The door opening and closing control device according to claim 1 ,
wherein at the time of the first controller controlling the driving of the actuator so as to perform the operation of opening or closing the door in accordance with the instruction indicating the operation of the operation switch, and
wherein, when re-operation of the operation switch is performed during automatic opening or closing of the door, the first controller controls the driving of the actuator in accordance with an instruction indicating the re-operation of the operation switch.

5. The door opening and closing control device according to claim 1 , further comprising:
a remote controller which is provided with the operation switch and configured to wirelessly transmit an operation signal that shows an operating state of the operation switch; and
a communication part configured to receive the operation signal transmitted from the remote controller,
wherein, when the communication part receives the operation signal from the remote controller,
wherein, unless the second controller is controlling the driving of the actuator so as to assist the manual operation of opening or closing the door,
wherein the first controller controls the driving of the actuator in accordance with the operation signal.

6. The door opening and closing control device according to claim 1 , which controls opening and closing of the door provided on a vehicle, the door opening or closing control device further comprising
a traveling state detector configured to detect whether or not the vehicle is traveling based on information concerning traveling and stopping of the vehicle, the information is acquired from a vehicle-side device,
wherein, at the time of the traveling state detector detecting non-traveling of the vehicle and the second controller controlling the driving of the actuator so as to assist the manual operation of opening or closing the door, even when the operation switch is operated, the first controller does not control the driving of the actuator in accordance with the instruction indicating the operation, and the second controller continues to control the driving of the actuator,
wherein, at the time of the traveling state detector detecting non-traveling of the vehicle and the second controller not controlling the driving of the actuator so as to assist the manual operation of opening or closing the door, when the operation switch is operated, the first controller controls the driving of the actuator in accordance with the instruction indicating the operation, and
wherein, at the time of the traveling state detector detecting traveling of the vehicle, when the operation switch is operated, the first controller controls the driving of the actuator in accordance with the operation.

7. The door opening and closing control device according to claim 5 ,
wherein the operation switch is provided in at least each of an operation part in the driver's seat and the remote controller of the vehicle,
wherein at the time of the traveling state detector detecting traveling of the vehicle, the first controller controls the driving of the actuator in accordance with an instruction indicating the operation of the operation switch of the operation part in the driver's seat, and
wherein at the time of the traveling state detector detecting non-traveling of the vehicle and the second controller not controlling the driving of the actuator so as to assist the manual operation of opening or closing the door, the first controller controls the driving of the actuator in accordance with an instruction indicating the operation of the operation switch of the operation part in the driver's seat or of the operation switch of the remote controller.
