Electric parking brake control device

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.

1. An electric parking brake control device comprising:
at least one actuator that drives at least one motor configured to operate or release at least one electric parking brake; a control unit that controls the at least one actuator; a storage unit that stores a state of the at least one parking brake; at least one determining unit that determines the state of the at least one parking brake based on current that flows into the at least one motor; and a detecting unit that detects an ON/OFF state of an ignition switch, wherein, when the detecting unit detects that the ignition switch is in the ON state, the at least one actuator sends current in a direction which causes the at least one parking brake to be operated to the at least one motor, and the at least one determining unit determines whether the at least one parking brake is in an operation state or a release state based on the current which flows to the at least one motor, wherein the control unit compares a state of the at least one parking brake determined by the at least one determining unit with a state of the at least one parking brake stored in the storage unit, and wherein, when the state of the at least one parking brake determined by the at least one determining unit and the state of the at least one parking brake stored in the storage unit are in agreement with each other, the control unit controls the at least one actuator such that the at least one parking brake maintains the states which are in agreement with each other.
