<p>A controller for a motorised vehicle, e.g. a front wheel drive wheelchair, receives control signals from a user input device, e.g. X,Y joystick, and is configured to control a motor arrangement of the vehicle in dependence on the control signals, wherein the controller comprises an acceleration control unit 60 configured to determine a centripetal force factor corresponding to a centripetal force which is currently acting on the vehicle as a result of the control signals, and is configured to calculate an acceleration limit for the motorised vehicle in dependence on the centripetal force factor. The acceleration control unit is configured to apply the acceleration limit by modifying a response of the controller to the control signals, such that the motorised vehicle does not exceed the acceleration limit. Preferably, the acceleration limit is calculated by a calculation unit 130 within the acceleration unit 60. Also disclosed is a method of controlling a motorised vehicle using the controller, a computer program product for use in the method, and a motorised vehicle comprising the controller.</p> |
