Abstract
For the development and testing of ABS/ESP control units, both the detailed simulation of the vehicle and drive train dynamics as well as the dynamic behaviour of the hydraulic system are important. The signals coming from the control unit that control the valves in the brake hydraulic system cause pressure changes in the brake system and thus affect the braking torque. In turn, the changes in the speed of the wheels are fed back to the control unit via sensors. The objective of an ABS control strategy is to prevent the wheels from locking during braking in order to ensure and maintain the steerability of the vehicle, while the ESP action also attempts to achieve a stabilization of the yawing motion by means of active braking.
