Basis for innovative driver assistance systems and automated driving
The ECU links the electric steering to the electrical system of the vehicle and to other vehicle components. In this way, the electric power steering has access to parameters such as speed, steering angle, wheel revolutions and yaw rate. On the basis of these, the ECU can continuously calculate the longitudinal and lateral guidance of the vehicle as well as the optimal steering assistance, and intervene correctively with the aid of driver assistance systems in emergency situations. The vehicle manufacturer decides which driver assistance systems are used and in which way. For instance, it is possible to influence the lateral guidance of the vehicle in dangerous situations to prevent accidents or lessen the consequences.
In future applications for highly automated driving, redundant electronics are provided in order to ensure control of the servo assist function in the event of a fault.
