Abstract: An apparatus for controlling the movement of a material transfer vehicle with respect to the front end of a paving machine that is being supplied by the material transfer vehicle includes a controller that is mounted on the material transfer vehicle and is operatively connected to drive systems for controlling the steering and speed of the material transfer vehicle. A sensor is mounted on the material transfer vehicle and is operatively connected to the controller. The sensor is located and adapted to execute multiple non-contact sensor scan passes across the front end of the paving machine to determine the distance from the sensor to the paving machine. The sensor is also adapted to communicate information to the controller about the distance from the sensor to the paving machine. The apparatus includes no components that are mounted on the paving machine.

Abstract: An apparatus for controlling the movement of a material transfer vehicle with respect to the front end of a paving machine that is being operated by a driver/operator and is being supplied with asphalt paving material by the material transfer vehicle includes a controller that is mounted on the material transfer vehicle and is operatively connected to control mechanisms for controlling the speed and braking of the material transfer vehicle. A sensor is mounted on the material transfer vehicle and is operatively connected to the controller. The sensor is located and adapted to execute non-contact sensor scan passes across the front end of the paving machine to determine the distance from the sensor to the paving machine. The sensor is also adapted to communicate information to the controller about the distance from the sensor to the paving machine. The apparatus includes no components that are mounted on the paving machine.

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.

Abstract: A material transfer vehicle that is adapted to supply asphalt paving material to a paving machine on a roadway has a discharge conveyor with an input end and an output end 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 elevation control signals to the elevation control system for the discharge conveyor so that the elevation of the discharge conveyor may be adjusted based upon communication from the controller. The controller is also adapted to communicate steering control signals to 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 based upon communication from the controller. 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. The paver-locating sensor is also adapted to communicate information to the controller about the distance and orientation of the paving machine with respect to the paver-locating sensor.
