Abstract: The mobility of a vehicle having first and second pairs of diagonally opposite wheels is extended when the pressure on a given wheel is abnormally low. A load on the first pair of wheels defines a first load diagonal, and a load on the second pair of wheels defines a second load diagonal. A disequilibrium between the first and second load diagonals is induced by actuation of a level corrector comprised of at least two actuators each acting on a respective side of the vehicle, for reducing a load borne by said given wheel and thereby extending the mobility thereof.

Abstract: A technique for compensating side pull in a vehicle, the suspension system of the steering axle of the said vehicle comprising a virtual pivot point. The method applies a steering torque (Cg) to the wheel-carrier (2g) by way of one of the arms (5g, 6g) of the virtual pivot point.

Abstract: The invention concerns a method and a system for extending the mobility of a vehicle, which consists in substantially reducing the load borne by a wheel of the vehicle when the pressure in the tyre of the said wheel is abnormally low.
