摘要： A system and method for automatically coupling at least one of an air line or an electrical line of a tractor to a trailer that is configured to be pulled by the tractor. A moveable arm is mounted to the tractor and is configured to exhibit at least one degree of freedom (DOF) of motion relative to the tractor. The moveable arm carries at least one of an air line connector or an electrical connector. A trailer coupling head is mounted to the trailer and carries at least one of an air line connector or an electrical connector that are configured to be connected to the at least one of an air line connector or an electrical connector of the tractor. The trailer coupling head can be moved in at least a vertical DOF relative to the ground by the automatic coupling system.

摘要： A method detects and prevents stall of a drive motor of an autonomous electric tractor. A stall detector receives, at intervals, a motor current value from a drive circuit of the autonomous electric tractor, determines when the motor current value reaches or exceeds a first current threshold and applies brakes, inhibits a throttle controlling the drive motor, and sets a motor stall flag. A method determines a height above the ground of a landing gear of a trailer coupled with a tractor. A lift detector controls a hydraulic pump to pump a hydraulic fluid into a chamber of a piston coupled to a fifth wheel of the tractor to raise the fifth wheel. The lift detector senses, at intervals as the fifth wheel rises, a pressure value of the hydraulic fluid in the chamber and processes the pressure value to determine when the landing gear is lifted off the ground.

摘要： 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.
