In order to obtain the best energy recovery during regenerative braking, vehicles with an electrified drive train will increasingly be equipped with new brake systems which provide a free distribution of braking force between the wheel brake and the electric motor. The hydraulic brake system therefore has to be completely decoupled from the driver’s input at the brake pedal. The generation of hydraulic pressure is designed for permanent operation in contrast to conventional ESCsystems. This article intends to demonstrate how traction and driving experience can be improved by using new, more capable brake actuators in comparison to existing systems like traction control and ESC, which solely affect the stability of the car respectively its wheels. Due to better NVHcharacteristics, the brake can already be applied at standstill. Interventions below the threshold of traction control will then be possible and acoustically acceptable. First results will be presented on the basis of driving simulations and measurements.     «
