Detecting inclined installation of vehicle navigation unit involves using acceleration sensor that measures Earth's acceleration to determine installation orientation wrt. vehicle vertical axis

摘要

The method involves using an acceleration sensor that measures the Earth's acceleration to determine the installation orientation of the navigation system (3) wrt. the vertical axis (8) of the vehicle (1). The acceleration sensing system (6) determines the component of the Earth's acceleration in the sensitive axis of the sensor. An Independent claim is also included for a navigation system and for a vehicle with a navigation system contg. a location module.
