Systems and methods for determining a height of an object above a vehicle

In some embodiments, a range sensor is configured to detect a distance between a portion of a vehicle and an object above the portion of the vehicle. In some embodiments, the detected distance may be presented to an operator to allow the operator to control a height of an adjustable suspension in order to manually control the distance. In some embodiments, the detected distance may be used to automatically control the distance. In some embodiments, the distance may be controlled in order to allow the vehicle to couple to the object, such as a fifth wheel of the vehicle coupling to a kingpin of a trailer.

Suspension component damage detection with marker

A detected displacement of a marker on a vehicle is determined based on image data captured while the vehicle traverses a displacement object of a ground surface. Then a health status of a suspension component of the vehicle is determined to be unhealthy based on comparing the detected displacement of the marker to a target displacement of the marker. The target displacement specifies displacement of the marker that indicates the suspension component is healthy. The vehicle is operated based on the suspension component being unhealthy.
