Force-based determination of a setpoint gear combination for multiple drive systems

Abstract

The invention relates to a method for determining a target gear combination for a vehicle having at least two drive systems, wherein each drive system drives a vehicle axle and each of the two drive systems has at least one electric motor and at least one transmission with in each case at least two gears; wherein the method comprises the following step: determining the target gear combination on the basis of a comparison of a longitudinal force demand with maximum total driving forces and/or minimum total resistance forces of possible gear combinations of the at least two gears of the at least two transmissions, wherein the maximum total driving forces are the sum of the maximum driving forces of the possible gear combinations and the minimum total resistance forces are the sum of the minimum resistance forces of the possible gear combinations.
