Abstract
A method controls a motor vehicle including an internal combustion engine coupled to a first axle set and to at least two electric machines each one coupled to one wheel of a second axle set. The method includes determining the speed of at least one of the electric machines; comparing the determined speed against a threshold; and altering, if the determined speed is above the threshold, the maximum torque of the electric machines so as to limit the rotational speed of the machines.
