Backstepping is a method designed to control nonlinear systems. Formulated for the first time and described by Petar Kokotovic around 1990. The main purpose of backstepping is stabilisation of each subsystem’s structure; the function needs to be of an adequate class. The present task consists in minimising the vehicle body displacement from the position of equilibrium after it has been knocked out of it with the force exerted on the wheel, which has the purpose of simulating the wheel encountering an obstacle. The model depicts ¼ of the vehicle suspension with a conical spring or classical spring, and the damper with magnetorheological fluid which modifies damping of the suspension. The Mathcad programme facilitated the calculations, the model was designed using the Matlab – Simulink environment. Simulations were carried out on the model with the linear characteristics of a spring, as well as on the model with the implemented nonlinear spring. All the investigated cases were accompanied by the control tests that comprised building the model without control, i.e. with the constant value of damping
