Abstract: Improving the safety of the car, including its controlled, is one of the main and complex tasks of the automotive industry, maintenance and traffic control services. Improving the operational characteristics of the car, aimed at preventing or at least reducing the severity of injuries in road accidents, was carried out in this thesis in the direction of improving controllability, stability and reliability, improving living conditions in the car cabin. The choice of vehicle parameters that provide the best characteristics of controlled and related stability guarantees optimization. Based on this: the acting forces acting on the car when driving along a circular path at a constant low speed; considered the phenomenon of drift of a car wheel associated with the lateral elasticity of the wheel, to a degree affecting the handling and stability of the car; from consideration of the turning scheme of a car with elastic wheels, a graph of the car's handling was built, which connects the parameters (turning radius and speed of the car, the angle of rotation of the steered wheels, centrifugal force, the difference in the angles of withdrawal of the rear and front wheels of the car) the movement of the car along a curve the definition for the critical speed under controlled conditions is determined, which allows to determine three cases of occurrence of neutral understeer and oversteer of the vehicle.
Key words: analysis, influence of the technical condition of the vehicle, stability, the dependence of the angular deviation, the car, the speed when braking the car, when one front or one rear braking mechanism.
