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

A method of adjusting a height of a vehicle frame, the method comprising:

• receiving, by an electronic control unit (ECU), a distance value from a range sensor connected to
• a portion of the vehicle frame that extends behind a cab of the vehicle and is aimed in an upward direction, wherein the distance value represents a distance between the range sensor and an object over the range sensor;
• determining, by the ECU, an adjustment amount to raise or lower the vehicle frame based on the distance value;
• and
• transmitting, by the ECU, a command to an adjustable suspension system to raise or lower the frame the determined adjustment amount.

A non-transitory computer-readable medium having computer-executable instructions stored thereon that, in response to execution by an electronic control unit (ECU) of a vehicle, cause the ECU to perform actions for adjusting a height of a vehicle frame of the vehicle, the actions comprising:

• receiving, by the ECU, a distance value from a range sensor connected to a portion of the vehicle frame that extends behind a cab of the vehicle and is aimed in an upward direction, wherein the distance value represents a distance between the range sensor and an object over the range sensor;
• determining, by the ECU, an adjustment amount to raise or lower the vehicle frame based on the distance value;
• and
• transmitting, by the ECU, a command to an adjustable suspension system to raise or lower the frame the determined adjustment amount.
