Title: AUTOMATIC VEHICLE GUIDANCE METHOD AND SYSTEM
Abstract:
The invention relates to an automatic vehicle guidance method according to which infrastructure data are wirelessly transmitted to the vehicle (10) and vehicle guidance instructions are calculated by using this infrastructure data. The method is characterized in that the infrastructure data for at least one segment of the route (40) located immediately ahead is loaded into an on-board memory (44), in that the actual position of the vehicle (10) is continuously determined by a precise positioning system (14), and in that the instructions are calculated by using the position data and the stored infrastructure data.
