Abstract
A front wheel drive motorized vehicle controller comprises: a control signal interface receiving control signals from a user control device indicating at least a demanded forward speed; an acceleration measurement interface, receiving acceleration measurements from at least one vehicle-mounted acceleration sensor, providing a first and second acceleration measurements with respect to first and second axes, the motorized vehicle being configured to be driven in a plane defined by the first and second axes; an acceleration magnitude calculation unit calculating an acceleration magnitude in dependence on the first and second acceleration measurements; a speed modification unit calculating a forward speed reduction factor in dependence on the acceleration magnitude and applying the forward speed reduction factor to the demanded forward speed to produce an applied forward speed; and a motor control unit controlling the speed of the left and right drive wheels in dependence on the applied forward speed.
