The safe and stable control ofa vehicle undoubtedly belongs to one of the most important requirements that relate to the vehicle 's design and operation. Consequently, in the near future, so called steer-by-wire systems could become the next stage in the control system development. A number of new, modern vehicles presented by car makers at important car shows definitely show how topical the issue is. If we want to create a design for this steering system, we have to know the action offorce very well. An experimental laboratory establishment for measuring and optimizing the steering system of vehicles was developed in our centre. The testing equipment is made of aluminium sections enabling the equipment to be quickly adapted to various vehicles ' axles and tyres. An exchangeable mat located under a tyre enables the system to create behaviour simulation for various surfaces with a different coefficient of adhesion. A sliding way assisted by a hydraulic jack under a tyre allows a change in axle load for example in accordance with the vehicle 's occupancy. A force sensor will be positioned between the jack and the mat to monitor the load adjustment. The testing stand design enables us to determine responses and behaviour of the system including tyres.The safe and stable control ofa vehicle undoubtedly belongs to one of the most important requirements that relate to the vehicle 's design and operation.
