System for estimating the speed of a vehicle (1) comprising means (11) to determine a first parameter based on the rotational speed of a first set of wheels (5) of the vehicle, such as its drive wheels, and means (14) to estimate the speed of the vehicle (Vestimate) using said first parameter. The system also comprises means (12) to determine a second parameter based on the rotational speed of a second set of wheels (4) of the vehicle and means (16) to identify any difference between said first and second parameters. <IMAGE>
