Systems and methods for automated operation and handling of autonomous trucks and trailers hauled thereby
A system and method for operation of an autonomous vehicle (AV) yard truck is provided. A processor facilitates autonomous movement of the AV yard truck, and connection to and disconnection from trailers. A plurality of sensors are interconnected with the processor that sense terrain/objects and assist in automatically connecting/disconnecting trailers. A server, interconnected, wirelessly with the processor, that tracks movement of the truck around and determines locations for trailer connection and disconnection. A door station unlatches/opens rear doors of the trailer when adjacent thereto, securing them in an opened position via clamps, etc. The system computes a height of the trailer, and/or if landing gear of the trailer is on the ground and interoperates with the fifth wheel to change height, and whether docking is safe, allowing a user to take manual control, and optimum charge time(s). Reversing sensors/safety, automated chocking, and intermodal container organization are also provided.
1. A system for operating a truck in a yard comprising:
an autonomous truck and a hitched trailer responsive to a processor onboard the truck and a remote server;
a dock-mounted safety system that indicates when movement of the hitched trailer away from the dock is authorized, the processor onboard the truck determines a state of movement authorization, the processor and remote server, responsive to the state of movement authorization, further instructing the truck to move when indicated by the safety system; and
a lever assembly of the truck configured to employ appropriate hydraulic lifting actuators to raise the hitched trailer at its front end, and thereby secure a hitch between the autonomous truck and the hitched trailer for movement away from the dock.
2. The system as set forth in claim 1 , wherein the safety system comprises a multi-color signal light operatively connected with the server and the processor.
3. The system as set forth in claim 1 , wherein the safety system comprises a multi-color signal light and the truck includes a sensor that reads a state of the multi-color signal light.
4. The system as set forth in claim 1 , wherein the safety system comprises a locking mechanism that selectively engages a portion of the hitched trailer when movement away from the dock is not enabled.
5. The system as set forth in claim 1 , wherein a dock-lock is activated at a loading dock, once the hitched trailer is securely placed against bay door, and thereafter loading/unloading is initiated.
6. A system for assisting reverse operations on a trailer hitched to an autonomous truck comprising:
a moving sensor assembly mounted on a linear guideway, the guideway being mounted laterally on a structure adjacent to a plurality of parking areas for trailers to be received, the sensor assembly moving along the structure to a location corresponding to a parking area of the plurality of parking areas for the hitched trailer and providing sensor data related to a space behind the hitched trailer that is employed by at least one of a facility control server for the autonomous truck and an on-board controller of the autonomous truck.
7. The system as set forth in claim 6 wherein the sensor assembly includes at least one of a vision system camera, LIDAR and radar.
8. The system as set forth in claim 7 wherein the guideway is mounted with respect to a loading dock.
9. The system as set forth in claim 8 wherein the guideway comprises at least one of a rail, wire and track.
10. A system for operating a truck in a yard comprising:
a dock-mounted safety system that indicates when movement of a hitched trailer to dock is authorized;
an autonomous truck and the hitched trailer operationally responsive to a processor onboard the truck and a remote server, the processor onboard the truck determining a state of movement authorization, and responsive to the state of movement authorization, the processor and remote server further instructing the truck to move when indicated by the safety system; and
a lever assembly of the truck configured to employ appropriate hydraulic lifting actuators to lower the hitched trailer at its front end, and thereby unhitch the hitched trailer from the autonomous truck for movement by the truck away from the unhitched trailer.
