Parking assistance device for motor vehicle, has shaping units to restrain beams presenting sections with shapes viewed by driver when shapes appear on obstacle to allow driver to estimate vehicle position when beams are intercepted

摘要

The device has two shaping units (MF111, MF211) arranged to restrain two parallel visible light beams (F111, F211) to be presented with transverse sections, where the beams are delivered by two visible light sources (S111, S211) e.g. head light. The transverse sections are respectively formed with two visual differential shapes viewed by eyes of a driver when the shapes appear on an obstacle (O) to allow a driver to estimate a position of a motor vehicle (V) with respect to the obstacle according to relative positions of the shapes when the beams are intercepted by the obstacle.
