Abstract: A vehicle position detection and guidance system for use with an automotive service lift having a pair of runways onto which a vehicle is driven in order to be elevated. The system consists of a LiDAR sensor disposed to provide a field of view encompassing a volume of space extending upward from the upper surface of each lift runway, as well as the intervening region between the runways. The LiDAR sensor to observes at least the leading tread surfaces of two or more wheels on a vehicle approaching the service lift, and a volume of space below the vehicle. Output from the LiDAR sensor is conveyed to a processing system, which monitors the wheel positions relative to the runway surfaces, and provides output indicating steering corrections, obstructions, and a vehicle stopping point as the vehicle is driven onto the runways and/or the lift elevation changes.
