1. A vehicle control system comprising:
a non-inertial sensor arrangement configured to detect a parameter indicative of a radius of turn for a vehicle that is desired by a driver of the vehicle; a speed detection arrangement operable to detect a forward speed of the vehicle; a friction estimation arrangement configured to provide an estimated value for a coefficient of friction between at least one tire of the vehicle and a surface over which the vehicle is driven; and a processor connected to receive signals from the non-inertial sensor arrangement, the speed detection arrangement and the friction estimation arrangement, wherein the processor is configured to: determine a desired radius of turn from the signals received from the non-inertial sensor arrangement, and generate a value for the desired radius of turn; calculate a maximum safe speed for the vehicle, based on the desired radius of turn and the estimated value for the coefficient of friction, the maximum safe speed representing a forward speed at which the vehicle can safely negotiate a turn having the desired turn radius of turn; and generate a speed reduction signal to instruct speed of the vehicle to be reduced if a detected forward speed of the vehicle exceeds the maximum safe speed. |
