Abstract
A method and system corrects steering of a vehicle upon a brake system malfunction. The brake system has a diagonal split layout. An electronic brake system (EBS) controls operation of the master cylinder. An electronic power steering system (EPS) includes sensors to measure motion and torque of a steering column of the vehicle and includes a motor to provide torque to the steering column. During driver braking when one of the brake circuits has failed, the system calculates a yaw torque value introduced by a driver braking with just one functioning brake circuit. Based on a steer wheel angle and a steer wheel torque obtained from the sensors of the EPS and on the yaw torque value, a steer wheel torque request defining a steer wheel torque/angle needed to counter the yaw torque value is calculated and sent the EPS which operates the motor to compensate for the steering deviation.
