Patent DE-19856184-A1 (DE)
Inventor: BEIER WOLFGANG
IPC: G07B15/00
Filed: 1998-12-05
Abstract: The method involves providing the course of the streets in the vehicle as a data set and at least two separate setting algorithms. The algorithms are used to combine movement-related data, especially the distance from an exit position, vehicle rotation and position data obtained using a global positioning system, with the data set of street characteristics. The algorithms extend from an exit position, especially from a reference point (3') based on three measurement co-efficients. One co-efficient relates an East-West distance obtained from geographical latitude co-ordinates in proportion to an odometer determined distance between the current position and the exit position. One co-efficient relates a North-South distance obtained from geographical latitude co-ordinates in proportion to the odometer determined distance between the current position and the exit position. One co-efficient relates to a gyrometrically determined vehicle rotation, especially between the exit and current positions, in proportion to the odometer determined distance between the current position and the exit position. An Independent claim is included for a system for implementing the method.
