A ground movement system for a land transport vehicle (2) capable of levitating, the vehicle having a plurality of wheels including at least one actuated wheel (3), a drive device (6) for driving the actuated wheel and/or a brake (8) for braking the actuated wheel (3), a vertical positioning actuator (9) arranged to move the actuated wheel (3) vertically relative to a fuselage of the vehicle (2), and control means arranged to act, during an acceleration stage and/or during a braking stage of the vehicle, to control the vertical positioning actuator (9) as to adjust the vertical position of the actuated wheel in order to increase the load carried by the actuated wheel and thus increase the maximum force that can be transmitted to the ground by the actuated wheel so as to increase the maximum drive and/or braking torque that can be produced by the drive device (6) and/or by the brake (8) without the actuated wheel (3) skidding or slipping.

A status tracking system for tracking a suspension system or a physical condition of the parts in a steering system in vehicles. The status tracking system includes a sensor unit connected with the body of the part, and a processor unit configured to connect with the sensor unit in a manner receiving the measurements made by the sensor unit as input. The processor unit is configured to obtain measurement information from the measurements it receives, generate status information by classifying the measurement information according to a reference value in a memory unit, and display the status information on a user interface.

A computer system for performing an axle load adjustment action of vehicle axle of a vehicle is provided. The computer system including processing circuitry is configured to obtain tire data, and obtain at least one adjustment parameter, wherein at least one adjustment parameter is requirement data pertaining to the weight of the vehicle, axle load requirements of the vehicle, and the legal requirements for the road on which the vehicle is or will be travelling, determine an axle load adjustment action based on at least one adjustment parameter and based on tire data, and execute said axle load adjustment action, wherein the axle load adjustment action includes an temporarily increase of the load of the at least one axle of the vehicle.
