Choosing the control action on the steering of vehicles

\nThe requirements for the controllability of vehicles regulated in Global Technical Regulations No. 8 (GTR No. 8) are analyzed. It is noted that it is impossible to directly compare the controllability of vehicles due to the fact that the law of rotation of the controlled wheels when performing tests using this technique varies from the design features of the car, in particular from the length of the wheelbase. A single law of rotation of controlled wheels for movement is proposed, both for a material point and for structures of real vehicles. The methods of obtaining a single idealized path by the magnitude of deviations from which it is possible to assess the change in the controllability of any vehicle are described. The results and conclusions obtained in the work allow the manufacturer to more reasonably approach the choice of vehicle parameters to ensure road safety.\n
