Methods and apparatus for determining a corrected current load pitch angle of a vehicle for headlamp beam height adjustment using a gravitation sensor

A non-transitory machine readable storage medium comprising instructions to cause programmable circuitry to at least:

• determine an initial value of a load pitch angle of a vehicle based on output from a gravitation sensor of the vehicle when the vehicle is stationary;
• determine a change in the load pitch angle;
• determine a correction parameter of the vehicle based on a chassis behavior of the vehicle;
• determine a current value of the load pitch angle based on the initial value of the load pitch angle, the change in the load pitch angle, and the correction parameter;
• and
• control a movement of a headlamp of the vehicle based on the current value of the load pitch angle.

An apparatus for headlamp adjustment of a vehicle, the apparatus comprising:

• a gravitation sensor;
• machine-readable instructions;
• and
• programmable circuitry to execute the machine-readable instructions to:
• determine an initial value of a load pitch angle of the vehicle when the vehicle is stationary based on output from the gravitation sensor of the vehicle;
• determine a change in the load pitch angle;
• determine a correction parameter of the vehicle based on a chassis behavior of the vehicle;
• determine a current value of the load pitch angle based on the initial value of the load pitch angle, the change in the load pitch angle, and the correction parameter;
• and
• adjust a position of a headlamp of the vehicle based on the current value of the load pitch angle.
