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.
