Abstract
When two (in particular electric) drives operate on wheels decoupled from each other in a motor vehicle, the drives should have an identical construction and the same properties. However, if one drive is stronger than the other, distribution factors other than 0.5 must define the target torque for the two drives, i.e. the fraction of a total torque, in order to provide a correction. The distribution factors are determined while the motor vehicle is in operation. For this purpose, a steering angle and an additional quantity such as the lateral acceleration or the yaw rate are determined and a check is performed to determine if the additional quantity has the correct functional dependency on the steering angle.
