Abstract (en)

[origin: DE19602170A1] A method is proposed for improving the control characteristics ofa brake pressure regulation system for vehicles and involves the following: the turning characteristics of the individual vehicle wheels are determined with wheel sensors, a vehicle reference speed (approximately equal to the vehicle speed) and vehicle reference acceleration are determined by logical connection and evaluation of the sensor signals, a brake pressure control signal is formed and brake pressure control signals are generated in accordance with a predetermined regulation mode, and vehicle acceleration sensors are used to determine vehicle body acceleration. The difference between the vehicle reference acceleration (aref; 13) and car body acceleration (aKar; 14) is determined and evaluated to ascertain the road conditions at a given moment. The regulation mode or algorithm is then varied in accordance with the difference signal ( DELTA ; 16).
