EPAS Fail-Safe Control using Differential Braking

One of the main systems for ground vehicles is Electric Power Assisted Steering (EPAS). Due to its importance, a redundant system usually implemented. This solution remain however expensive, especially small urban cars. paper proposes an alternative fail-safe control algorithm using this time differential braking. Controlling each brake apart generates yaw moment enabling turning vehicle. Optimal coordination ensured due importance maneuver. Results show that braking, already exist in most passenger cars, able generate sufficient additional help driver steer his/her can reduce space and cost
