Abstract

A front hood assembly has a front hood of a motor vehicle that is hinged to the chassis of the motor vehicle via at least one hinge, said front hood being lockable via at least one hood lock. The hinge comprises means for displacing a joint depending on the vehicle speed to an upper or a lower position, independent of whether a collision with a pedestrian has taken place or not. The assembly provides a protection for pedestrians that is technically feasible and can be implemented at low cost. In a method for actuating the front hood of a motor vehicle depending on the vehicle speed, the front hood is displaced into a lifted position at least in the area of its hinges if a lower threshold value of the vehicle speed is exceeded or if the vehicle speed falls below an upper threshold value.
