An information and/or control system for a vehicle includes a positioning unit for determining a current geographic position of the vehicle, a map unit containing information at least regarding routes on which the vehicle may travel, and an interface unit for selective output of information from the map unit as a function of the current geographic position. Furthermore, information, referred to as a virtual traffic sign, regarding properties of a section of a drivable route is stored in the map unit in correlation with a geographic position along this route. This information is outputable by the interface unit when the distance of the vehicle from this geographic position is less than a limit value.

Information and control system for vehicles

A headlight illumination field regulating apparatus includes an electromagnetic radiation emitter, a reflected radiation sensor, an evaluation unit, and a unit for adjusting the alignment position of the headlights. The electromagnetic radiation emitter operates to radiate electromagnetic radiation on the road to the front of the automobile and the reflected radiation sensor senses reflected radiation and creates a data point representative of the irradiated spot. The evaluation unit evaluates the data points to establish the position of the detected spot or area and thereafter compares the evaluated position with a predetermined desired position and subsequently generate a correction signal to control the regulation or adjustment of the headlights into a proper light projecting orientation which ensures a proper projection limit of the beam of the headlight.

Apparatus for regulating the illumination field of a vehicle headlight

A headlight illumination field regulating apparatus includes an electromagnetic radiation emitter, a reflected radiation sensor, a comparing element, and a unit for adjusting the alignment position of the headlights. The electromagnetic radiation emitter operates to radiate two electromagnetic radiation beams on the road to the front of the automobile and the reflected radiation sensor senses reflected radiation and determines a relationship of a sensed characteristic of the first radiation beam and a sensed characteristic of the second radiation beam and creates a data point representative of the irradiated spot. The comparing element thereafter compares the determined relationship between the sensed reflected radiation characteristics with a predetermined desired position and subsequently generate a correction signal to control the regulation or adjustment of the headlights into a proper light projecting orientation which ensures a proper projection limit of the beam of the headlight.
