The present disclosure relates to a motor driving circuit of an electronic parking brake system, which is configured to include a first motor and a second motor for releasing or applying a parking brake applied to different wheels, respectively; and a first ECU and a second ECU for controlling the driving of the first motor and the second motor, respectively, wherein the second ECU is prevented from intervening in the driving of the first motor and the second motor while the first ECU drives the first motor and the second motor, and controls the driving of the first motor and the second motor only when there is an abnormality in the first ECU.

Motor driving circuit for electronic parking brake system

An electronic control unit (ECU) includes a first signal processor and a second signal processor. The first signal processor selectively receives current wheel speed information detected by a sensing device, detects a signal of the current wheel speed information, and processes the detected signal. The second signal processor communicates with the first signal processor, selectively receives the current wheel speed information detected by the sensing device when the first signal processor is in a faulty state, and detects and processes a signal of the current wheel speed information.
