The paper outlines simulation studies and investigations of a hydraulic actuated brake (HAB) and an alternative electromechanically actuated brake (EMB) system on a half-car model using the Simulink environment. The vehicle simulation model used is briefly explained as follows. Both implementations build on a brake by wire technology, which is essentially an interface for driver assistance. The input is obtained from 0-100% brake actuation converted into pressure applied to the brake system. This gives scope for further development, for example increasing brake pressure in emergency situations and traction control. Additionally, it covers safety aspects in design and implementation. For example, a design for a hydraulic based brake-by-wire pedal emulator with failed power braking requirements may be found in Zehnder et al. (1999). In the paper various ABS control strategies utilizing HAB and EMB technologies are evaluated and compared. The ABS control strategies are outlined and comparisons of the results are discussed.
