A method for actuating an actuator device of a roll stabilizer for a vehicle. The actuator device has a supply line connection for supplying a supply voltage, a converter for supplying an alternating voltage using the supply voltage, and at least two phase lines for supplying the alternating voltage to actuator connections of an actuator which can be operated using the alternating voltage. The method has a step of reading an interruption signal, which indicates an interruption in the supply of the supply voltage or a deviation from the supply voltage at the supply line connection and a step of providing a protection signal at an interface with a protection device using the interruption signal in order to at least partly prevent a generator voltage which is or can be fed into the phase lines via the actuator connections from being forwarded in response to the protection signal.

Method and device for actuating an actuator device, and actuator device

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