PROBLEM TO BE SOLVED: To reduce cost, by reducing the number of components equivalent to touch sensors, by preventing nipping by a door, without providing the touch sensor.SOLUTION: A door opening-closing control device comprises a motor for changing opening of a door, an angle sensor for detecting a rotation angle of the motor, and a motor control part for controlling the motor on the basis of a detection result of the angle sensor. The motor control part stops the motor or rotates the motor in the inverse direction of closing operation when a driving current of the motor exceeds a predetermined threshold value in closing operation of the door, and sets the predetermined threshold value low as the opening of the door detected by the angle sensor becomes low.SELECTED DRAWING: Figure 1 |
