Definitions

• TravelPilot comprises an autonomous navigation device working with a coupling location, stored street maps and a navigation computer.
• the vehicle has an antenna and a receiver which receives the satellite signals of the so-called "Global Positioning System” and forwards them to a navigation computer which compares the vehicle position determined in each case with a digital map stored in a data memory.
• relativistic influencing factors can also be taken into account, so that a position determination with an accuracy of a few meters is possible.
• the position of the vehicle determined in each case is indicated to the vehicle occupants as required via acoustic or optical information carriers, so that the vehicle driver is able to reach the previously programmed travel destination in the shortest possible way.
• the navigation computer is alternatively also connected to a vehicle-side position determination system which comprises a compass and motion sensors which are arranged in the wheel area.
• This alternative position determination system provides a second quantity of data for processing by the navigation computer, by means of which a failure of the satellite signals can be bridged at least for a short time.
• DE 3925057 proposes storing additional triggering points arranged in the road map in the navigation system, the position of which is signaled to the driver when the vehicle is approaching.
• trigger points can e.g. B. stops or sights.
• the purpose of the monitoring devices the road users z. B. by maintaining the prescribed speed or traffic-adapted driving to protect against accidents in particularly hazardous areas, often missed.
• the invention has for its object to provide a position determination system that makes the driver aware of their presence in good time when approaching traffic monitoring devices.
• a data memory in the form of a CD-ROM, a floppy disk or the like is provided. This data can be queried, for example, by means of a CD-ROM drive and, after comparing the position determined by the computer with the stored position data of the monitoring devices, can be displayed optically and / or acoustically.
• the data memory can also have a partial memory that can be programmed via radio signals.
• the information that the vehicle is approaching a traffic monitoring device is preferably passed on with the aid of an optical or acoustic signaling device, so that the vehicle driver can adapt to the presence of such devices in good time by adapting his driving style.
• the computer When the vehicle is started up, the computer is first switched on. B. makes a position determination of the current location of the vehicle by means of the satellite signals. The position coordinates of the traffic monitoring devices are then z. B. read by means of a CD-ROM drive or the radio programmable partial memory and compared with the calculated position coordinates of the vehicle. This adjustment is constantly updated when the vehicle is moving, so that when the vehicle approaches a stored traffic monitoring device, an optical and / or acoustic message can be sent to the vehicle driver.
• the known satellite-based navigation systems can be easily combined with the system according to the invention.
