Abstract: When different vehicle dynamic control systems are integrated into an overall concept, the potential to influence the vehicle dynamics rises, thus increasing the potential of performance in safety-critical driving situations. The potential of active steering, powertrain and braking systems and their combinations is investigated systematically in order to increase the efficiency of an evasive manoeuvre assistant. Different powertrain topologies are taken into account. A vehicle dynamics control is presented that determines the actuator control signals for different actuator configurations. An algorithm to evaluate the maximum coefficient of friction serves as the basis to decide on how the actuator signals are distributed to the individual wheels. This study supports selecting promising concepts in the broad variety of possible combinations of available systems.
