System for estimating the speed of a vehicle by determining a first parameter based on the rotational speed of a first set of wheels of the vehicle, such as its drive wheels, and to estimate the speed of the vehicle (v<SUB>estimate</SUB>) using the first parameter, determining a second parameter based on the rotational speed of a second set of wheels of the vehicle, identifying any difference between the first and second parameters and from that determining the actual speed, indicating the actual speed and controlling the actual speed to a maximum. |
