Abstract:
1. A method of assisting steering of steered wheels of a vehicle, comprising: calculating an angular speed and an angular acceleration of a steering wheel of the vehicle; comparing the angular speed of the steering wheel to a threshold speed; comparing the angular acceleration of the steering wheel to a threshold acceleration; and when the angular speed is greater than the threshold speed and the angular acceleration is greater than the threshold acceleration, applying a phase advance between the steering wheel and a rack element so as to decrease a response time of the vehicle to an action of a driver of the vehicle on the steering wheel, wherein a steered wheels steering preset is emitted to an actuator to control the rack element, the steering present being calculated as a function of the angular speed and the angular acceleration of the steering wheel, and wherein the steering preset is calculated based on an angle of steer of the steered wheels and a temporal advance, according to the following equation: α
