摘要： An electric parking brake control device has an actuator that drives a motor configured to operate or release an electric parking brake, a control unit that controls the actuator, a storage unit that stores a state of the parking brake, a determining unit that determines the state of the parking brake based on current that flows into the motor, and a detecting unit that detects an ON/OFF state of an ignition switch. When the detecting unit detects that the ignition switch is in the ON state, the actuator sends current in a direction which causes the parking brake to be operated to the motor, and the determining unit determines whether the parking brake is in an operation state or a release state based on the current which flows to the motor.

摘要： A motor control device has a motor driving unit that drives a motor, a current detecting unit that detects a motor current flowing through the motor, a control unit that compares a detected current value of the motor current detected by the current detecting unit with a target current value to obtain a deviation, to control the motor driving unit based on the deviation, and a compensation unit that sets as a current offset value a detected current value of a drift current detected by the current detecting unit in a state where the motor current is regarded as zero, to compensate the detected current value of the motor current by the current offset value. The compensation unit sets a target offset value according to the current value of the detected drift current to correct the current offset value stepwise until the current offset value reaches the target offset value.
