Abstract
A method for determining a limit speed for driving, for a driver at a vehicle's steering wheel, includes a step of estimating a grip potential available at a given instant between a tire of the vehicle and a roadway on which a tire of the vehicle is running. The grip potential is estimated as a function of at least one of: a known influencing parameter, and a measured influencing parameter. The method also includes a step of determining a need for grip as a function of a driving situation of the vehicle and driving characteristics of the driver. The method further includes a step of determining a limit speed for driving as a function of the need for grip and the estimated grip potential. By virtue of the limit speed for driving, it is possible to prevent exceeding an estimate grip potential available.
