IMPROVEMENT OF SPEED REGULATION ON MOTOR VEHICLES BY INDICATING THE BRAKING DISTANCE

VERBESSERUNG DER GESCHWINDIGKEITSREGELUNG IM KRAFTFAHRZEUG DURCH DIE ANZEIGE DES BREMSWEGES

From the results of the research on human capabilities in connection with the driving of motor vehicles an information flow diagram is derived which takes into account the essential viewpoints of information recording and information processing in the steering of motor vehicles. It results from these considerations that it is advisable to divide the steering functions into a regulation of the transverse dynamics of the vehicle and into a regulation of the longitudinal dynamics. In contrast to the regulation of the transverse dynamic for which a continuous guidance is given by the course of the road, no suitable quantity exists for the regulation of the longitudinal dynamics. The continuous indication of the braking distance being required to bring the vehicle to a stop with present road conditions and present speed would result in an improvement of the regulation of the longitudinal dynamics. A technical concept is developed ensuring the indication of the braking distance by a continuous measurement of the closed linkage factor. In order to guarantee the improved comparison aimed at between guiding quantity and slaving quantity a head- up-display with analogue indication is proposed by which the driver gets the impression that the point at hich his vehicle would come to a standstill in case of an emergency braking is marked by a light beam across the street. The utilization of the indicated braking distance by the driver in the closed feedback control system is shown on the basis of some selected examples. /Author/
