Abstract

A method for operating a floor-bound heavy-duty transportation vehicle that can be displaced on rubber tires, such as a heavy-duty transportation vehicle that may be operated without a driver, comprising an electric drive having at least two electric motors. In order to improve the overall efficiency of the electric drive of a floor-bound heavy-duty transportation vehicle, the at least two electric motors are operated using optimized variables by a drive control and according to the operational conditions of the heavy-duty transportation vehicle and its performance requirements.
