    摘要： A vehicle includes one or more laser scanners and an on-board vehicle computer system communicatively coupled to the laser scanners. The computer system uses information (e.g., coordinate points) obtained from the laser scanners to calculate a trailer angle (e.g., a cab-trailer angle) for the vehicle. The computer system may include a shape detection module that detects a trailer based on the information obtained from the laser scanners and an angle detection module that calculates an angle of the detected trailer relative to a laser scanner, calculates the orientation of the detected trailer based on that angle and dimensions (e.g., width and length) of the trailer, and calculates a cab-trailer angle based on the orientation of the trailer. The computer system may include an autonomous operation module configured to use the cab-trailer angle in an autonomous or computer-guided vehicle maneuver, such as a parking maneuver or backing maneuver.

    摘要： A vehicle computer system controls downhill speed of a vehicle having a cruise control and an engine retarder. The system receives a request to increase engine retarder demand. In response, the system increases an engine retarder demand setting and, if cruise control is active, decreases a downhill speed control (DSC) cruise control offset. The engine retarder system may automatically activate to reduce the vehicle speed to a cruise control set speed plus the DSC cruise control offset. In an embodiment, the request to increase engine retarder demand is generated in response to operator input via an engine retarder demand input device (e.g., a steering-column-mounted control stalk). The system may also receive a request to decrease engine retarder demand in the engine retarder of the vehicle. In response, the system decreases the engine retarder demand setting and, if cruise control is active, increases the DSC cruise control offset.

    摘要： In some embodiments of the present disclosure, augmented reality and/or virtual reality technologies are used to present information for a vehicle to a technician. A virtual object model file that includes a context model and at least one assembly detail model is created based on a vehicle design model. A VR/AR device uses its camera to generate video of a vehicle, and superimposes a depiction of a vehicle component or assembly from the virtual object model file over the video in the location in which the vehicle component or assembly is actually located, as if the vehicle were “see-through.” The VR/AR device may then also allow the technician to select specific components of the depicted assembly in order to retrieve and display detailed information about the component.

    摘要： A platooning light fence includes an illumination assembly having one or more light sources located on at least one of a first platooning truck and a second platooning truck, each of the one or more light sources configured to radiate a beam of light that extends substantially continuously between the first and second platooning trucks. A system for deterring passenger vehicles from entering a gap defined between at least a leading platooning truck and a trailing platooning truck includes an illumination assembly having one or more light sources located on at least one of the leading platooning truck and the trailing platooning truck, each of the one or more light sources configured to radiate a beam of light that extends substantially continuously between the leading and trailing platooning trucks, and an activation assembly configured to selectively activate the illumination assembly.
