    摘要: A connecting system and a method for connecting a towing vehicle to a semitrailer includes a first plug unit configured to be fixed to a rotor of a semitrailer unit rotatably mounted on the semitrailer unit about an axis of rotation and having a first coupling portion, and a second plug unit having at least one mounting portion configured to be attached to a coupling plate of a commercial vehicle and a second coupling portion, wherein the first and second coupling portions are configured to be coupled together along a coupling axis such that the coupling axis is substantially parallel to the axis of rotation and spaced from the axis of rotation, and such that the first coupling portion is displaceable relative to the rotor and/or the second coupling portion is displaceable relative to the mounting portion along the coupling axis to engage or disengage the respective opposite coupling portion.

    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 safety system for a towing vehicle and a towed object including a towing vehicle coupling, a towed vehicle connection point that is engageable with the towing vehicle coupling, a coupling lock that is movable between a locked and unlocked positions, a lock sensor that is operative to detect whether the coupling lock is in the locked or unlocked position, a brake system that is moveable between a brake system engaged position and a brake system disengaged position, a controller, wherein the controller is in operative connection with the lock sensor and the brake system, and wherein the controller is operative to receive signals from the lock sensor, wherein in response to a signal from the lock sensor indicating the coupling lock is in the locked position, the controller is operative to enable the brake system to be in the disengaged position through manipulation of manual parking brake valve.

    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.
