METHOD OF PREVENTING OVERSTEERING AND AUTOMOBILE EQUIPPED WITH POWER-ASSISTED STEERING PREVENTING OVERSTEERING

The method involves generating a signal e.g. sound and/or light alert signal, when an effort associated to the behavior of tires of front wheels (1) e.g. steering wheels, under deformation, exerted on a steering rack (6) decreases with respect to a lateral effort and a speed of rotation of a flywheel (2) is higher than a threshold speed, where movement of the rack is due to the effort, torque applied by the fly-wheel and power torque applied by an electric motor (5). A residual function of time is defined from the effort exerted on the rack and from the lateral effort exerted on the tires. An independent claim is also included for a motor vehicle equipping an electrical power assisted steering system for orienting a train of steering wheels.
