Abstract
A vehicle (1) having: a chassis portion (2) and a tilting suspension arrangement (10) such that the chassis portion can tilt relative to ground; a tilt control arrangement (50) including at least a tilt controller and a tilt motor (48) to selectively apply a torque between the chassis portion (2) and at least one member (12) of the tilting suspension arrangement (10). The tilt controller has an active, tilt-controlled first mode (200) which adjusts a tilt angle (a) of the chassis towards an unstable equilibrium position using the tilt motor (48). The tilt controller has a primarily passive, free-tilt second mode (220) in which the tilt angle of the chassis is not adjusted for at least fifty percent of time. The tilt controller selectively permits a transition between the first mode and the second mode in dependence on at least one operating parameter of the vehicle.
