An electric parking brake system (10) includes a wheel (20) driven by an electric motor (26) to move a vehicle (1), a parking brake (22) maintaining the wheel (20) stopped, a parking brake actuator (32) operating the parking brake (22), and a drive controller (40) controlling the parking brake actuator (32). The drive controller (40) controls the electric motor (26) to maintain the wheel (20) of the vehicle (1) stopped while the vehicle (1) is parked, and calculates a parking torque (Ptr) based on a control amount of the electric motor (26) that maintains the wheel (20) stopped. The drive controller (40) calculates a necessary braking force for the parking brake (22) to maintain the wheel (20) stopped based on the calculated parking torque (Ptr), and controls the parking brake actuator (32) so that the necessary braking force is generated.
