The vehicle level sensors used in different automotive control system:

• Headlight levelling control:
  • this system guaranty that the vehicle doesn’t dazzle others users on the road.
  • it also guaranty that the lighting range is always maintained.
• Active suspension control:
  • comfort and safety: maintain chassis stability and vehicle height constant.
  • safety and fun to drive: adapt suspension performances to road and drive conditions, and allow the driver select modes (sport, comfort).
• Load monitoring:
  • for safety purpose the system monitor the vehicle load and balancing.

The sensor body is fixed on the chassis, and a rotational lever is attached on the wheel arm of the vehicle with a rod. This lever angle depends (and then the angle information provided by the sensor) on the angle of the wheel arm.
