|Samenvatting||Automatic control of vehicle motion systems may have a great influence on enhanced safety. The purpose of this analysis is to present the possibility of improving vehicle performance by using automatic devices fitted to a vehicle. This paper presents the results of investigations of intelligent control of the braking, steering, suspension and power transmission systems of a vehicle, which is equipped with an antilocking braking device, traction control one, active suspension and four wheel drive. The dynamics of the vehicle were analysed under different road conditions. The solution of equations describing mathematical models is described. The equations were validated by the comparison of the results of calculation with these ones obtained from road tests. The algorithms of the control of all devices are proposed and realised by means of the fuzzy logic method. It outlines the process used to create fuzzy sets and the rules that define the fuzzy controller. The results of the simulation outline enhancement of the vehicle performance while using electronic control systems. For the covering abstract see ITRD E825082.|
