An electric parking brake system that includes a parking brake, and an electric motor, wherein the parking brake is activated by the electric motor. Operation of the parking brake is controlled such that a vehicle is decelerated at a target deceleration of a predetermined magnitude when an operation command to operate the parking brake is issued by a driver via an operation switch while the vehicle is running. If a service brake fails while a vehicle is running, when the driver depresses the operation switch to issue the operation command to a parking brake to brake the vehicle, the parking brake is controlled such that the vehicle is decelerated at the target deceleration of the predetermined magnitude set on the basis of the number of times of depressing the operation switch.
