Definitions
- the present disclosure relates to an electric parking brake device for a vehicle.
- Patent Document 1 describes an electric parking brake device that is fixed to a side surface of a side member on the outside of the vehicle below the floor panel of the vehicle compartment.
- the electric parking brake system is a braking system that is separate from the normal braking system using the brake pedal. It has the function of locking (restraining) the rotation of the rear wheels by automatically towing.
- the electric parking brake device incorporates a battery-driven motor. The operating state of the motor is controlled according to the operation of the passenger. For example, when the motor is rotated forward, the wire cable is pulled and the rear wheels are locked. Further, when the motor is reversely rotated, the pulling force of the wire cable is weakened and the rear wheels are unlocked. These operations are associated with, for example, button operations and accelerator pedal depression operations.
