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

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.

2. 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;

determining, by the vehicle controller, whether the ABS is operating by receiving a hydraulic control signal or hydraulic sensor signal of the ABS from an ABS controller that operates the ABS of the vehicle;

removing, by the vehicle controller, motor torque in response to determining that the ABS is operating;

detecting, by the vehicle controller, a wheel speed of the vehicle and a speed of the motor during the 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.

3. A system for controlling an operation of an Anti-lock Brake System (ABS) of a vehicle, comprising:

an ABS controller configured to enable an ABS operation signal when the ABS operation is necessary; and

a vehicle controller configured to:

receive the enabled ABS operation signal from the ABS controller and adjust an output of motor torque based on the received ABS operation signal,

detect a wheel speed of the vehicle and a speed of the motor during the ABS operation, and

generate and output regenerative braking motor torque during the ABS operation when a difference between the detected wheel speed and the detected motor speed is less than a predetermined reference value,

wherein the ABS controller is configured to operate the ABS when a signal indicating that the motor torque has been removed is received from the vehicle controller.

4. The system of claim 3 , wherein the ABS controller is configured to set a maximum standby time for the removal of the motor torque.

5. The system of claim 4 , wherein the ABS controller is configured to operate the ABS after the maximum standby time has elapsed.

6. The system of claim 4 , wherein the maximum standby time is extracted and set from a previously generated maximum standby time table based on a driving state and driving environments of the vehicle.

7. A non-transitory computer readable medium containing program instructions executed by a controller, the computer readable medium comprising:

program instructions that generate 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;

program instructions that receive an ABS operation signal that indicates whether the ABS operation is necessary from an ABS controller configured to operate the ABS of the vehicle;

program instructions that remove 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;

program instruction that detect a wheel speed of the vehicle and a speed of the motor during the ABS operation; and

program instructions that generate and output 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.

8. The non-transitory computer readable medium of claim 7 , further comprising:

program instructions that determine whether the ABS is operating by receiving a hydraulic control signal or hydraulic sensor signal of the ABS from an ABS controller that operates the ABS of the vehicle; and

program instructions that remove motor torque in response to determining that the ABS is operating.
