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.

Abstract: A method for route planning includes a) making an initial energy forecast for a journey route to a route destination using an initial speed for at least one section of the journey route. The method may also include: b1) making a first energy forecast for the journey route using a first speed for the at least one section; b2) making a second energy forecast for the journey route using a second speed for the at least one section; b3) determining whether the journey route, based on the second energy forecast, includes n or n?1 charging stops; and b4) if the journey route includes n charging stops, determining the first speed as specified speed for the at least one section of the journey route, or if the journey route includes n?1 charging stops, repeating steps b2) and b3) with a third speed for the at least one section.
