Abstract
A target gear combination for a vehicle having at least two drive systems is determined. Each of the two drive system drives a vehicle axle and each of the two drive systems has at least one electric motor and at least one transmission has at least two gears The target gear combination is determined based on one or more of a route profile lying ahead, a speed and/or an acceleration of at least one vehicle driving ahead or driving, and a distance from at least one vehicle driving ahead or driving behind.

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 motor and at least one transmission, wherein at least one of the transmissions has at least two gears, the method comprising:
- determining the target gear combination based on (i) a route profile lying ahead of the vehicle as determined by a digital map or by a sensor system of the vehicle, (ii) a speed of at least one surrounding vehicle, (iii) an acceleration of at least one surrounding vehicle, or (iv) a distance from the at least one surrounding vehicle, wherein the surrounding vehicle is another vehicle driving ahead or behind the vehicle;
- and
- selecting and activating the determined target gear combination for the transmissions between the drive axles and the motors.
