Teoretické řešení dynamiky jízdy vozidla řízeného všemi koly

In Section 2.1 an actual state in steering of passenger cars also by back wheels is analyzed. In Point 2.1.2 back axles making only passive steering possible are treated. In Point 2.1.3 active systems are discussed. The quantities that determine at single systems back wheels turn are specified; main types of apparatus for back wheels moving are characte-rized. In Point 2.1.1 legitimates on cars with all wheels steering are mentioned. In Point 2.1.4 trends of development in steering systems are adumbrated. The major aim was to predict behaviour of a car that can steer, dependently upon chosen quantities, also with back wheels. In Point 2.2.2 the abstract plane one-track model as a basis for further considerations is dis-cussed. The input of an assembled mathematical model (equations describing motion of the model are written in Point 3.2) was as a consequence of the study in Point 3.1 the front Wheel *) an-gle. In relation to the aim, three problems were scrutinized (Section 3.3). The first problem was behaviour of the model at steering under given dependences of the back Wheel angle on the front Wheel angle. The second problem was behaviour of the model in the case of back Wheel turn being linearly dependent on the yaw velocity. The third problem was behaviour of the model at zero sideslip angle in the centre of gravity. In Point 3.4 drive maneuvers used at computations are defined. In Chapter 5 pieces of knowledge obtained through an analysis of graphical results are spe-cified.
