According to the present invention, a brake can be operated while appropriately using a parking brake mechanism, power consumption can be reduced, an operating time of the brake can be effectively extended especially when an auxiliary power supply is used, and effects on the performance and feeling of the brake are maximally reduced while using the parking brake. The electric brake system is provided with a parking brake mechanism (5) which maintains braking force through mechanical engagement. The electric brake system is provided with an auxiliary power supply (25) in addition to a main power supply device (19), and a power supply control device (24) which switches whether to use the auxiliary power supply (25). A power monitoring control means (23) is provided which monitors the power supply state and assists in the retention of power supply through the auxiliary power supply (25) when it is determined that the power supply state is below a predetermined state. The parking brake mechanism (5) is configured to be operated without manipulation of a driver while the auxiliary power supply (25) is used. |
