Abstract (en)
[origin: WO2013182257A1] The present invention relates to a method of providing sensory feedback to a vehicle driver when driving close to the grip limits of a tire of a front vehicle wheel, the method comprising steps of: determining (42) a current lateral slip state ( Sy ) of the tire; estimating a tire-road coefficient of friction (mu), based on measurement (41 ) of a normal force (Fz) acting on the vehicle wheel and of at least one of a lateral force (Fy) and a longitudinal force (Fx) acting on the wheel; estimating (43) a peak lateral slip state (S ymax ) at which maximum tire lateral force can be generated, based on the determined current lateral slip state and the estimated friction coefficient; providing sensory feedback to the driver (45), whereby the feedback has a magnitude that varies as a function of the difference between the peak lateral slip state and the current lateral slip state.
