Abstract
In this study were developed theoretical and experimental researches regarding the braking performances of passenger cars on roads with different adherence coefficients, in concordance with the improvement of active safety and the reduction of accidents with severe consequences. In order to validate the ABS/ASR system working algorithm and to accentuate the influences over the braking/starting processes with and without ABS respectively ASR, a plane dynamic model was done for a single wheel of the passenger car. This simplified model of the passenger car has two inertial elements: a wheel and a mass in translational movement (the vehicle). In order to confirm the theoretical results obtained some experimental tests were realized.
Keywords: active safety, ABS, vehicle dynamics, Matlab-Simulink, model, simulation.
