Future on-board vehicle control systems can be further improved through new types of mechatronic systems. In particular, these systems'' capacities for interaction enhance safety, comfort and economic viability. The Automotive Engineering Department (fzd) of Darmstadt University of Technology is engaged in research of the mechatronic vehicle corner, which consists of three subsystems: sensor tire, electrically actuated wheel brake and smart suspension. By intercommunication of these three systems, the brake controller receives direct, fast and permanent information about dynamic events in the tire contact area provided by the tire sensor as valuable control input. This allows to control operation conditions of each wheel brake. The information provided by the tire sensor for example helps to distinguish between straightline driving and cornering as well as to determine μ-split conditions.

With the view to many new opportunities with actuation devices of oncoming Brake-by-wire-systems, the active driving safety could be increased by means of vehicle braking dynamics on the one hand and by means of optimization of the driving conditions during braking on the other hand. This is a strong focus of the brake-pedal and Brake-by-wire research at the Department of Automotive Engineering at Darmstadt University of Technology (fzd) and the ‘Sonderforschungsbereich’ IMES (Mechatronics for Mechanical Engineering) of the ‘Deutsche Forschungsgemeinschaft’ (DFG) with task B6. To study the brake pedal feel, a new research vehicle focusing on an adjustable brake pedal has been developed. In view of the wide range of influences on brake pedal feel, this car allows systematic research of the brake system's man/machine interface.
