Analysis of an accelerating model of motor vehicle with the uncontrolled steering wheel

In this paper a continuation of the previous research has been presented. A simulation of a vehicles acceleration in various road conditions but without a drivers control has been taken into account. The main aim of this paper was to answer the question whether the random road conditions could affect the vehicle while accelerating while a driver cannot control the direction of its motion. The three various maximum amplitudes of the irregularities for both the dry and the icy road surface were used. Almost different road profiles were also adopted for the analyzed maneuver, which defines a specific coefficient. Apart from no control of the vehicle the initial speed was set to 5 km/h and after 1 s the vehicle started to accelerate. The time of reaching the full throttle (100%) was only 0.25 s which provided a rapid acceleration. The simulation time was 10 s.
