1. A method of monitoring functionality of a pedestrian detecting device for a vehicle, the method comprising the acts of:

  • generating, by a sensor operatively coupled to the pedestrian detecting device, sensor signals indicative of a current operating condition of the pedestrian detecting device of the vehicle;

    storing, in a memory of the vehicle as a target value, a first sensor signal that is generated by the sensor upon the vehicle being parked;

    storing, in the memory of the vehicle as an actual value, a second sensor signal that is generated at a point in time after the vehicle has been parked and when the vehicle is restarted;

    comparing, the actual value with the target value to determine any deviation of the actual value from the target value resulting from an impact while the vehicle has been parked; and

    determining, the functionality of the pedestrian detecting device as a function of the comparison, wherein the pedestrian detecting device comprises an absorber on a bumper of the vehicle, the absorber being deformable in an event of a collision with a pedestrian, wherein deformation due to the collision is transmitted to a connecting element that actuates the sensor to generate the sensor signal.
