Abstract

A device for operating an active roll stabilization system of a vehicle is described, which active roll stabilization system has a roll stabilizer on at least one axle of the vehicle, which roll stabilizer is configured to adjust, by use of an electrically operated actuator, a degree of twist between lever arms of the roll stabilizer which act on different sides of the axle, in order to counteract a roll movement of the vehicle. The device is set up to determine which operating mode of a plurality of different operating modes of the roll stabilization system has been selected by a user of the vehicle. Further, the device is set up to operate the actuator as a generator, in order to recuperate electrical energy from a roll movement of the vehicle and/or from a roadway-induced movement of the vehicle, in a manner dependent on the selected operating mode.
