Abstract
A material transfer vehicle has a discharge conveyor with a discharge chute mounted thereon. A controller is operatively connected to the elevation control system and the steering control system for the discharge conveyor. The controller is adapted to communicate with the elevation control system for the discharge conveyor to adjust the elevation of the discharge conveyor. The controller is also adapted to communicate with the steering control system for the discharge conveyor so that the angular orientation of the discharge conveyor with respect to the longitudinal axis of the material transfer vehicle may be adjusted. A paver-locating sensor is operatively connected to the controller, and is located and adapted to execute multiple non-contact sensor scan passes across the front end of the paving machine to determine the distance and orientation of the paving machine with respect to the paver-locating sensor and to communicate this information.
