The parking brake motor is the actuator in the Electronic Parking Brake (EPB) system, replacing the manual handbrake. Activated by a button, the motor applies or releases brake pressure on the calipers. EPB systems have two common designs: caliper-integrated motors and motor-driven cable systems; both use motor-driven cables or gear mechanisms to clamp the brake pads. They support hill-start assist, automatic hold, and remote parking features, integrating signals from ABS, vehicle speed, and incline sensors for intelligent control. Benefits include increased convenience and safety (e.g., preventing roll-away), but they also introduce complexity and demand high reliability from the motor, sensors, and ECU.
