Abstract: To control quick reverse operation while inhibiting generation of vibration when performing the reverse operation with respect to a car door during door-closing operation.SOLUTION: In a door control device 10, a speed command unit 102 determines a speed command value in accordance with reverse operation when a reverse command for instructing the execution of the reverse operation in which door-opening operation is performed while stopping door-closing operation is input during the door-closing operation of a door 12. A constant switching unit 103 applies a second-kind door control constant (control constant for reverse operation) prepared for stopping the door-closing operation in the reverse operation, which is different from a first-kind door control constant for normal door opening/closing operation (control constant for normal opening/closing), to a door control constant. A control arithmetic unit 105 executes control arithmetic operation corresponding to the speed command value determined by the speed command unit 102 by using the applied second-kind door control constant.SELECTED DRAWING: Figure 2
