Abstract: The electric brake actuator with a parking function is provided with: detection unit which is provided in a vehicle in which the electric brake actuator is provided and is capable of detecting movement of the vehicle from a stop state; and determination unit configured to determine whether or not a locking mechanism has shifted to a parking locking state, by using a detection signal outputted from the detection unit, when the locking mechanism is driven by an actuator so as to switch from an unlocking state to the parking locking state.

Abstract: An electric brake device includes an electric motor; a braking force application mechanism configured to apply a braking force on a vehicle wheel; a lock mechanism configured to assume one of a locked condition; a temperature sensor configured to measure an ambient temperature of a vehicle; and a freezing preventive power supply unit configured to initiate supply of an electric power to the electric motor or a drive source of the lock mechanism. The freezing preventive power supply unit interrupts the supply of the electric power to the electric motor or the drive source of the lock mechanism when the temperature detected by the temperature sensor exceeds a second preset temperature T2 that is higher than a first preset temperature T1.
