A mechanical system is set up to represent the motion of a tractor- semitrailer vehicle on a flat or inclined road. The driver is simulated by a controller. The system is modelled by a set of nineteen ordinary differential equations. Different types of losses of stability of the straight line steady state motion of the vehicle with and without driver control are investigated. The nonlinear stability analysis is done by means of centre manifold theory and singularity theory.
