Locating and navigation method and system for a motor vehicle has a gyro-sensor and GPS system with the position determined using GPS used to constantly correct the coupled position determined using the gyro-sensor

摘要

Locating and navigating method has the following steps: (a) Determination of a coupled position from the output position of a gyro-sensor (b) determination of an absolute, GPS, position (c) determination of the difference between coupled and absolute position (d) breaking down of the difference into first and second components for controlling the correction of the output signal. The difference vector is divided into two vector components: the first is for offset correction of the gyro-sensor output, the other for correction of the characteristic curve of the gyro-sensor. The invention also relates to a corresponding computer program product and a locating and navigating system.
