<p>When it is detected by velocity sensors (1-4, figure 1) that the vehicle is stationary 14 a slip threshold is set 15 by the controller (6, figure 1) to a low value so that virtually no wheel slip is allowed. Once the speed of the vehicle has reached a predetermined value, a higher wheel slip threshold is set 17 so that the vehicle's forward momentum can be maintained. This permits the vehicle to move off from rest without the wheels digging into a deformable surface, for example by controlling the throttle of the vehicle's engine (12, figure 1).</p> |
