Abstract: A method of detecting and utilizing a 3-dimensional (3D) position of a coupler of a trailer may include calculating a motion of a camera mounted to a vehicle; determining 2-dimensional (2D) positions of the coupler within input images captured by the camera; estimating 3D estimated positions of the coupler based on the 2D positions of the coupler and the motion of the camera; optimizing the 3D estimated positions of the coupler to generate adjusted 3D coupler positions; and filtering the adjusted 3D coupler positions to detect the 3D position of the coupler of the trailer.

Abstract: A system for fusing two or more versions of map data together includes one or more central computers that receive road network data representing a road network for a predefined geofenced area. The central computers receive road network data that includes a discrete random curve that represents lane markings. The discrete random curve includes a plurality of state vectors that are each defined by a respective location and tangent angle. The central computers estimate the position for the state vectors of the discrete random curve based on a signed distance and the tangent angle by minimizing a spatial Kalman filter cost function and execute a Kalman smoothening function to estimate the position and the tangent angle for the state vectors that are part of the discrete random curve, where the state vectors each represent a map point of the fused map data.

Abstract: A charging unit guidance system includes a processor and a memory. The memory includes instructions that upon execution by the processor, cause the processor to receive a sequence of user states associated with a user of a first autonomous vehicle, each user state being one of a walking state and an at-charging-unit state and the sequence of user states being based on a sequence of observed user speeds associated with detected user position data associated with movement of the user from the first autonomous vehicle to a charging unit and at the charging unit, determine a charging unit location of the charging unit based on a correlation between the at-charging-unit states in the sequence of user states and the user position data, and upload the charging unit location associated with the charging unit to an edge computing system, the edge computing system being configured to provide guidance instructions to the charging unit to a second autonomous vehicle based at least in part on the charging unit location.

Abstract: A method for generating garage parking notifications includes receiving current parked-vehicle data indicating that a vehicle has been parked inside a garage. The current parked-vehicle data includes the current location of the vehicle parked inside the garage. The method further includes determining whether the current location of the vehicle inside the garage is within a warning zone. The warning zone is an area inside the garage where the vehicle has not been frequently parked. The warning zone area is determined using historical parked-vehicle data. The method further includes generating a notification to warn an operator of the vehicle that the vehicle should be moved in response to determining that the current location of the vehicle inside the garage is within the warning zone.

Abstract: A system for active roll control for a vehicle body is provided and includes a sensor operable to monitor a tilt of the body and a suspension system. The suspension system includes an active sway bar including a first bar portion, a second bar portion, and an active roll control motor disposed between the first bar portion and the second bar portion. The active roll control motor is operable to turn the first bar portion in relation to the second bar portion. The system further includes a computerized active roll control controller which is operative to monitor a driving mode including one of straight-line driving and rounding a curve on a road, monitor an output of the sensor, determine a desired roll moment based upon the driving mode and the output of the sensor, and control the active roll control motor based upon the desired roll moment.

Abstract: A vehicle, operating system of a vehicle and a method of operating a vehicle is disclosed. A local electronic control unit is operated at the vehicle in order to control the vehicle. A backup electronic control unit is operated at a remote computing platform for control of the vehicle. A control of the vehicle is transferred from the local electronic control unit to the backup electronic control unit upon occurrence of a fault at the local electronic control unit.

Abstract: A process for correcting longitudinal roll from an offset load using active roll control within a vehicle is provided. The process includes, within a computerized controller using axle-based control to control a suspension system, operating programming to control pneumatic pressure supplied to each of a plurality of air spring devices within the suspension system to execute a vehicle leveling event including one of adjusting a height of the vehicle or maintaining the height of the vehicle. The process further includes operating programming to, simultaneously with the controlling the pneumatic pressure, utilize a plurality of active sway bars to provide an offset torque to the vehicle body. Each of the plurality of active sway bars is associated with one of a plurality of axles. Providing the offset torque is based upon a number of moles of air in each of the plurality of air spring devices and reducing the longitudinal roll.
