Abstract
A motor vehicle has an actuator device for raising a bonnet in an accident to minimize injury to a pedestrian. The actuator device has at least two actuators for raising the bonnet. A control unit activates actuators with a time delay. Alternatively, the actuators differ in power. The time delay between activating the actuators or the differing power of the actuators reduces vibration while raising the bonnet, thereby ensuring proper raising of the bonnet and enhancing protection to the pedestrian.
