The present invention relates to a control device and a control method for an electric braking system, which prevent partial braking due to an operation error of an actuator based on the electric braking system. The present invention provides a control device for an electric brake system, which controls the actuators respectively provided in each wheel hub for the braking of the electric brake based on the brake signal transmitted from the pedal simulator, and is characterized in that it includes: a braking force calculation unit , calculating the target braking force and the braking force of the actuator according to the braking signal; the system failure judging unit compares the deceleration of the vehicle with the target braking force, and judges whether the electric braking system is faulty; and an actuator failure judging unit, wherein the system failure judging unit judges a failure and judges whether the actuator is faulty. As a result of the judgment by the actuator failure judging unit, it is judged that a specific actuator is faulty, and the braking force calculation unit recalculates the braking forces of other normal actuators other than the faulty actuator.
Description
technical field [0001] The invention relates to a control device and a control method of an electric brake system. More specifically, the control device and control method for an electric brake system according to the present invention prevent bias braking due to an operation error of an actuator in the electric brake system. Background technique [0002] Along with the rapid development of the automobile industry, the development of technologies that can meet the increasing safety of automobiles and the increasingly intensified environmental and safety restrictions on automobiles is in progress. [0003] In particular, technologies related to vehicle safety are being developed into active safety control systems (Active Safety Control System) through integration with technologies in the electronics and control fields. With regard to the car brake (Brake) system, developed such as ABS (Antilock Brake System, anti-lock braking system), EBD (Electronic Braking Force Distributi...
