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; and a first sensor for generating a speed signal indicative of a speed of the driven wheel. The control apparatus may calculate acceleration of the one wheel using changes in the speed signal over time and calculate an acceleration of the vehicle using torque applied by the traction motor and a mass of the vehicle.
