Abstract

A stabilizer (105) for the anti-roll stabilization of a vehicle (100). The stabilizer (105) has a first stabilizer element (110) and a second stabilizer element (115). The first stabilizer element (110) is, or can be, coupled to a first wheel suspension element (120) of the vehicle (100) and the second stabilizer element (115) is, or can be, coupled to a second wheel suspension element (125) of the vehicle (100). Furthermore, the stabilizer (105) is provided with an electric motor (135) designed to rotate the first stabilizer element (110), relative to the second stabilizer element (115) in response to a control signal, so as to decouple the first wheel suspension element (120) from the second wheel suspension element (125). In this case the control signal represents a signal determined on the basis of a field-orientated control system.
