Vehicle navigation system based on a central route calculating computer linked via a communications network to an onboard vehicle guidance system that calculates a route automatically based on user identification and position

摘要

Navigation system for guiding users towards a target destination has a central route computer (10) that calculates a route from start to target destination and transmits it to a vehicle target guidance unit (15), that issues guidance instructions based on the user's actual position. A user identification unit (17) is used to transmit user identification to a central target input device (11) from which a target destination is determined based on time and user position data. The invention relates to vehicles that are used by different drivers, to cover different routes and involves calculating an optimum path for each standard route based on traffic conditions, etc. The computer automatically determines a target destination based on user identity, position and time. An Independent claim is made for a method for guiding users towards their target destinations.
