Driver Assistance Controller for Tire Saturation Avoidance up to the Limits of Handling

Electronic Stability Control (ESC) reduced the number of fatal crashes in single vehicle accidents in 32%, a ESC unit corrects the vehicle yaw rate avoiding under-steering or over-steering in relation to the drives intent. In recent years Steer-by-Wire systems have been proposed for driver assistance systems, this allows the development of controllers capable of predicting and avoiding exceeding saturation limits. This paper proposes a Model Predictive Controller to safely handle longitudinal and lateral driver intents up to the limits of handling on front wheel driven vehicles.
