A New Approach to Investigate the Vehicle Interface Driver / Brake Pedal Under Real Road Conditions in View of Oncoming Brake-by-wire-systems 1999-01-2949

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. The driver's judgment in driving experiments under real road conditions when changing brake pedal's idle travel and jump-in presented in this paper, will show the dependence of brake pedal parameters from braking situations.
