Simulation of a motor vehicle braking with the unlocked steering wheel

Abstract

In this paper the results of a simulation of a sports vehicle’s braking maneuver in the adopted road conditions has been presented. The aim of this paper was to analyze the results and compare them with the ones obtained in the previous paper by the author, also prepared for the acceleration maneuver. At the same time considerations on the damaging effect of the road irregularities have been presented as this time no straightforward steering was included, so the vehicle could move freely. The simulated braking of the vehicle’s model started at the speed of 100 km/h and its duration was 10 s.As in the previous paper the random road irregularities had three different amplitudes which enabled analysis of vehicle’s deceleration on a different road conditions each time. Almost different profiles were also assumed for the left and the right wheels of the vehicle’s model which moved on the dry and the icy road surface.
