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 mechanical component for a vehicle, having a measurement region with a surface, and at least one force sensor associated with the measurement region for detecting a force to which the component is exposed. The component () has, disposed in the measurement region, a hollow body () with a cavity () in which the at least one force sensor () can be positioned.

Mechanical component having a force sensor

A mechanical component for a vehicle, such as a ball stud, having a cylindrical measurement region with an outer surface. A force sensor is associated with the cylindrical measurement region for detecting at least one force to which the component is exposed. The forces detected by the nanotube sensor may include compressive and/or tensile stress forces. The force sensor includes a layer of carbon nanotubes applied to the outer surface of the cylindrical measurement region.
