Preliminary study on the issues of 4WS car control

Artykuł ma charakter przeglądowy i skupia się na problematyce sterowania samochodami 4WS (z czterema kołami skrętnymi). Przedstawiono najważniejsze idee dotyczące sterowania w pojazdach czterokołowych, rozwój historyczny, stan dzisiejszy i perspektywy konstrukcji samochodów 4WS. Omówiono w ujęciu systemowym całokształt zagadnień teoretycznych dotyczących sterowania kierunkiem ruchu pojazdu (w tym kwestie związane z modelowaniem matematycznym i badaniami symulacyjnymi ruchu pojazdu, kwestie syntezy i analizy algorytmów sterowania 4WS). Prezentowane studium oparte jest na dość bogatym przeglądzie literaturowym dotyczącym samochodów 4WS oraz na przemyśleniach kształtujących koncepcję rozprawy doktorskiej poświęconej algorytmom sterowania w samochodach 4WS.The article is an overview and it focuses on the control of 4WS cars (with four steered wheels). The most important ideas concerning the control of four-wheeled vehicles, the historical development, the present state and prospects for the construction of 4WS cars were presented. Theoretical issues related to the control of vehicle movement direction (including issues related to mathematical modelling and simulation studies of vehicle motion, synthesis and analysis of 4WS control algorithms) were discussed. The presented study is based on a fairly extensive literature review on 4WS cars and on thoughts that shaped the concept of the doctoral dissertation on control algorithms in 4WS cars

Study of the problem and the idea of operation of four-wheel-steering cars

The article takes the form of a review paper and focuses on the control problems of four wheel steering vehicles. The main issues related to the control of four wheel steering (4WS) vehicles, the historical development, the current state and the approach to the construction of 4WS vehicles have been discussed. The whole of theoretical issues related to the control of the car direction (including elements related to mathematical modelling and simulation studies of the vehicle motion, issues of synthesis and analysis of the 4WS control algorithms) were presented systemically. The presented collection of literature is based on a rather extensive review relating to 4WS cars and on considerations shaping the concept of development of the topic of control algorithms in 4WS cars. A preliminary concept of control in autonomous cars is also presented and will be explain what type of road manoeuvres it is going to analyse. The authors have also shown an example of the computational apparatus used
