  • Patent number: 9511795
    Abstract: The invention relates to a method to assist with turning a vehicle power assisted steering wheel, during which method a return setpoint (final return setpoint) quantifying a return force intended to be applied to said steering wheel in order to assist with returning said steering wheel to a predetermined central position is formulated, said method involving at least one step (a) of determining longitudinal acceleration during which step the instantaneous longitudinal acceleration of the vehicle is evaluated, followed by a step (b) of adapting the return setpoint during which step the steering wheel return setpoint is adjusted according to said instantaneous longitudinal acceleration so as to increase the intensity of the return force if said longitudinal acceleration increases, and thus notably compensate for the lessening of the natural centring effect that is caused by the lightening of the steering under acceleration conditions.
