Abstract

A system is provided for assisting with parking of motor vehicles in parking spaces, having at least one transmitter, arranged on the exterior side of the vehicle for transmitting a signal emitted at least approximately perpendicularly to the longitudinal axis of the vehicle and limited to a small emission angle range, and an assigned receiver for the reflected signal. The transmitted signal is formed of two partial beams having approximately flat surface area emission characteristics, the two areas being situated at least approximately perpendicular with respect to one another.
