Determining vectorial vehicle speed involves determining third value depending on comparison of first value from inertial sensors and second value from location device

摘要

The method involves determining a first value for the vectorial speed using inertial sensors, determining a second value using a location device and determining a third value depending on a comparison of the first and second values. The location device is a satellite-based system, especially a Global Positioning System. AN Independent claim is also included for the following: an arrangement for implementing the method.
