Abstract
The present invention is drawn to a light bar assembly for guiding the movement of a vehicle on a tilted surface. The light bar assembly is comprised of a housing having a light bar and a tilt sensor. The light bar is disposed in the housing and adapted to guide the movement of the vehicle. In addition, the tilt sensor is disposed in the housing and adapted to indicate the attitude of the vehicle. As such, the attitude of the vehicle is taken into consideration when the vehicle is being guided along the adjusted travel path on the tilted surface. Moreover, with the addition of the light bar assembly, an existing prior art guidance control system can be conveniently and economically upgraded to a robust system that includes the tilt sensor.
