Abstract

The invention relates to a device and method for controlling an electro-mechanical brake system. According to an electro-mechanical brake system, braking bias caused by the movement error of actuators can be prevented. The device for controlling an electro-mechanical brake system controls the actuators at the wheel hubs for the braking of an electro-mechanical brake based on braking signals transmitted from a pedal stimulator. The device for controlling the electro-mechanical brake system is characterized by including a braking force calculating part which calculates a target braking force and the braking force of the actuators based on braking signals, a system fault determination part which determines whether the electro-mechanical brake system has faults by comparing the deceleration of a vehicle with the target braking force, and an actuator fault determination part which determines whether the actuators have faults based on the fault determination condition of the system fault determination part. If the actuator fault determination part determines that a specific actuator has faults, the braking force calculating part calculates the braking force of other normal actuators except the faulted actuator.

Description

technical field [0001] The invention relates to a control device and a control method of an electric braking 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 brake system), EBD (Electronic Braking Force Distributi...
