PURPOSE:To drive a door by fixed driving force by computing the ratio door speed to door motor speed decided through a link mechanism to drive the door as a distance function, and adjusting the output torque of a door motor from the obtained speed reduction ratio and the prescribed closing force. CONSTITUTION:When a door opening command is output to a door control device 10, rotation of a door motor 4 is transmitted to a speed reduction pulley 5 through a belt, further transmitted to a chain pulley 6 through a chain so as to rotate a main link 7a and a following link 7b in the arrow mark directions, and doors 1a, 1b connected with the links through connecting members 9a, 9b are opened. In this case, output torque of the door motor 4 to always make the driving force constant regardless of a door position is searched, at first door motor speed is computed from the computed result of the present position of the doors, and the speed reduction ratio is obtained from this value. Next, the output torque of the door motor 4 is computed from the reduction ratio, and the motor torque command is so processed as to be subjected to the operation of a limiter on the basis the door motor speed deviation.
