Abstract
A vehicle is provided comprising: a main body; a plurality of wheels coupled to the main body; a traction motor associated with the main body and coupled to at least one of the wheels for driving the one wheel; control apparatus coupled to the traction motor and generating a motor drive signal to the traction motor; a first sensor for generating a velocity signal indicative of a velocity of the driven wheel; and a further sensor for sensing an acceleration of the main body and generating a vehicle acceleration signal. The control apparatus determining a measured velocity of the driven wheel from the first sensor speed signal, calculating a velocity of the vehicle using the vehicle acceleration signal and comparing the measured velocity of the driven wheel to the calculated velocity of the vehicle to determine wheel slip status.
