Abstract
A sensor device for measuring a motion of a vehicle includes a light source for radiating light on a region on a ground below the vehicle in temporal intervals and to produce a spot of increased temperature; a heat detection unit, which is mountable at an underside of the vehicle for detecting a position of the spot on the ground at the temporal intervals; and a control unit for receiving data about a measured time of the spot and the position of the spot from the heat detection unit and to estimate a change of the position of the spot in vehicle coordinates.
