Vehicle control arrangement

A vehicle control arrangement includes a mechanical interface configured to be interposed between an existing steering wheel column shaft and steering wheel of a vehicle. The arrangement includes at least two drive units, each configured to selectively engage with said mechanical interface upon activation for actuating the steering column shaft to steer the vehicle. Also included are a detector arranged in register with said mechanical interface and configured to detect manual interaction with the steering wheel, and a controller arranged in signal communication with the detector and drive units, the controller configured to, when autonomous control is selected, engage and control at least one drive unit to effect autonomous steering of the vehicle, and when manual interaction is detected, to disengage said drive units. In this manner, a vehicle is retrofittable with said control arrangement to facilitate alternating between autonomous and manual control, as required.
