Document Type and Number:
Japanese Patent JP7347038
Kind Code:
B2
Abstract:
To stably operate a relay switch that is provided to a power line of a motor.SOLUTION: A door ECU having a function of a motor control device includes a relay switch 61 that is provided to a power line 55 connecting a motor 10 to a driving circuit 41, a resistor 63 that is provided so as to be in series with a relay coil 61a of the relay switch 61, and a bypass switch 65 that is provided so as to be in parallel with the resistor 63. In addition, the door ECU includes a motor control unit 40 having a function of a switch control unit to control operations of the relay switch 61 and the bypass switch 65. Furthermore, the motor control unit 40 turns on the bypass switch 65 when connection control of causing an on-operation of the relay switch 61 by a current flow to the relay coil 61a is started. After the on-operation of the relay switch 61 is caused, the motor control unit 40 turns off the bypass switch 65.SELECTED DRAWING: Figure 4
