Orientation model for a sensor system

摘要

A sensor system for arrangement in a vehicle includes a plurality of sensor elements, a satellite navigation system, and a signal processing device. The signal processing device calculates and/or uses a first group of data of physical variables, whose values relate to a vehicle coordinate system, and calculates and/or uses a second group of data of physical variables, whose values relate to a world coordinate system, for describing the orientation and/or dynamic variables of the vehicle in the world.

1. A sensor system for arrangement in a vehicle, the sensor system comprising:
a plurality of sensor elements configured to detect at least partly different primary measured variables and use at least partially different measurement principles, a satellite navigation system, and a signal processing device, the signal processing device is configured to evaluate that it evaluates the sensor signals of the sensor elements and the output signals of the satellite navigation system jointly at least partially directly or indirectly, the signal processing device calculates and/or uses a first group of data of physical variables, whose values relate to a vehicle coordinate system, and wherein the signal processing device calculates and/or uses a second group of data of physical variables, whose values relate to a world coordinate system, wherein this world coordinate system is suitable at least for describing the orientation and/or dynamic variables of the vehicle in the world, wherein the vehicle coordinate system is defined as having a longitudinal axis of the vehicle, a transverse axis of the vehicle and a vertical axis of the vehicle, wherein the world coordinate system defines an orientation and/or dynamic variables of the vehicle in the world. the sensor system has an orientation model unit, with which the orientation angle between the vehicle coordinate system and the world coordinate system is calculated.
