The article investigates the potential of controlled vehicle suspension for off-road vehicles. The primary question is whether the controlled vehicle suspension can reduce the deformation of the deformable off-road (soil) and can become a soil-friendly suspension. The article represents the preliminary study of this problem, in the sense that the realistic but simple models for the vehicle, the tyre-off-road contact, and the suspension control have been chosen. The results described demonstrate that the specific soil-friendly vehicle suspension exists and the off-road (soil) deformation can be significantly reduced. If an off-road vehicle with a passive (but optimized) suspension is repeatedly passed across an off-road with an initial bump, then the initial bump is increased and developed into a long wavy road after the bump. Such wavy roads are typically seen on the off-roads after passing many vehicles. If the same experiment is realized with an off-road vehicle with a controlled (semi-active or limited-active) suspension, then the initial bump is decreased, and the development of the wavy road is suppressed. The usage of soil-friendly off-road suspension can be for both agricultural and military vehicles.
