Method for operating commercial vehicle for transportation of load, involves partially lifting trailer and/or semitrailer of vehicle to store potential energy, and partially lowering trailer and/or semitrailer to deliver stored energy

摘要

The method involves partially lifting a trailer and/or a semitrailer (1) of a motor vehicle i.e. commercial vehicle, to store potential energy. The trailer and/or the semitrailer of the motor vehicle are partially lowered to deliver the stored potential energy. The stored potential energy is used for driving the vehicle. A lifting and/or lowering device (10) is drivingly connected to a fluid machine. A load (5) and/or the trailer are totally or partially lifted/lowered such that change in center of gravity of the load does not affect driving behavior of the motor vehicle. An independent claim is also included for a motor vehicle.
