Regarding the evaluation of car stability during lateral slips

The purpose of this paper is to highlight the analysis of the way in which the automobile can enter the state of instability when curving and the influence of some construction parameters (position of the weight centre, axle track, elasticity of the tires) and functional parameters (speed, acceleration, braking) which can influence the dynamic behavior. In this paper, there are described some dynamic simplified models of the automobile when curving, the way in which the experimental determinations have been made when a real automobile is involed in many circular routes with speeds and rays that we know. This paper also describes the methodology of study and the devices used as equipment for the automobile during the study on routes in order to register some specific parameters important for limiting the possibility of the appearance of lateral slips.
