Vehicles with automatic headlight alignment

A vehicle, comprising:

• a vehicle body;
• a headlight that includes independently adjustable light sources and that is configured to produce headlight illumination on a surface in front of the vehicle body by activating different subsets of the independent adjustable light sources in sequence;
• sensor circuitry configured to obtain a surface measurement on the surface and configured to obtain partially activated headlight illumination measurements of the headlight illumination on the surface, each of the partially activated headlight illumination measurements corresponding to the activation of a given subset of the different subsets of the independently adjustable light sources;
• an electrically adjustable positioner configured to move the headlight relative to the vehicle body;
• and
• control circuitry configured to adjust the electrically adjustable positioner to align the headlight, wherein the control circuitry is configured to adjust, when aligning the headlight, relative output intensities of the independently adjustable light sources based on the partially activated headlight illumination measurements.

A vehicle, comprising:

• a vehicle body;
• a headlight;
• a positioner configured to move the headlight relative to the vehicle body;
• a three-dimensional sensor configured to measure a surface of an object in front of the vehicle body;
• an image sensor configured to measure a position on the surface where the headlight is pointed;
• and
• control circuitry configured to:
• calibrate the positioner when the vehicle is parked by directing the positioner to move while making sensor measurements to evaluate accuracy of the movement;
• use the measured surface to determine a predicated position on the object where the headlight is expected to be aimed when the headlight is aligned relative to the vehicle body;
• compare the measured position to the predicated position;
• and
• use the positioner to move the headlight based on the comparison.
