Abstract

An unintentional operation of a door is prevented while the usability of the door is improved. A power back door control device includes: an operation signal acceptor configured to accept an operation signal of a back door opening/closing switch for performing an operation of opening or closing a back door of a vehicle; a controller configured to control opening/closing of the back door via a motor when the operation signal acceptor accepts the operation signal; and a stopping state detector configured to detect whether or not the vehicle is in a stopping state based on information about traveling or stopping of the vehicle acquired by a vehicle-side ECU. When the stopping state detector detects that the vehicle is not in the stopping state, the controller performs fixing control of the back door so as to keep the back door from moving.

Claims

1. A door opening/closing control device, comprising:

an operation signal acceptor configured to accept an operation signal of an operation switch for performing an operation of opening or closing a door of a vehicle;

a controller configured to control opening/closing of the door via an actuator when the operation signal acceptor accepts the operation signal;

a stopping state detector configured to detect whether or not the vehicle is in a stopping state based on information about traveling or stopping of the vehicle acquired by a vehicle-side unit;

a position detector configured to detect an opening/closing position of the door;

a speed calculator configured to calculate an opening/closing speed of the door; and

a manual opening/closing detector configured to detect that the door has been manually opened or closed,

wherein, when the stopping state detector detects that the vehicle is in the stopping state, and when the manual opening/closing detector detects that the door has been manually opened or closed, the controller calculates assisting force based on the opening/closing position of the door detected by the position detector and the opening/closing speed of the door calculated by the speed calculator, and controls the actuator based on the assisting force to control the opening/closing of the door, thereby assisting manual operation of opening or closing the door, and

wherein, when the stopping state detector detects that the vehicle is not in the stopping state, regardless of whether the manual opening/closing detector detects that the door has been manually opened or closed, the controller performs fixing control of the door so as to keep the door from moving.

2. The door opening/closing control device according to claim 1,

wherein, when the stopping state detector detects that the vehicle is not in the stopping state, the controller sets a current position of the door as a target position of the door based on the opening/closing position of the door detected by the position detector, and

wherein, based on the target position set by the controller and a door position detected as needed in the position detector, the controller performs the fixing control of the door via the actuator so as to keep the door from moving.
