Method and system for controlling anti-lock brake system operation of vehicle

摘要

A method and system for controlling the operation of an Anti-lock Brake System (ABS) are provided. The system includes an ABS controller and a vehicle controller. The ABS controller enables an ABS operation signal when an ABS operation is necessary. The vehicle controller receives the enabled ABS operation signal from the ABS controller and adjusts the output of motor torque based on the received ABS operation signal. The ABS controller operates the ABS when a signal indicating that the motor torque has been removed is received from the vehicle controller.

1. A method of controlling an operation of an Anti-lock Brake System (ABS) of a vehicle, comprising:
generating, by a vehicle controller, a motor torque instruction that enables a motor to be operated based on a movement of an acceleration pedal or a brake pedal of the vehicle; receiving, by the vehicle controller, an ABS operation signal that indicates whether the ABS operation is necessary from an ABS controller configured to operate the ABS of the vehicle; removing, by the vehicle controller, motor torque when the ABS operation signal is received, and sending a motor torque removal signal indicating that the motor torque has been removed to the ABS controller to operate the ABS; detecting, by the vehicle controller, a wheel speed of the vehicle and a speed of the motor during ABS operation; and generating and outputting, by the vehicle controller, regenerative braking motor torque during the ABS operation when a difference between the detected wheel speed and the detected motor speed is lees than a predetermined reference value.
