Abstract: A computer in a vehicle is configured to operate the vehicle in at least one of an autonomous and a semi-autonomous mode. The computer is further configured to detect at least one condition of a roadway being traveled by the vehicle, the condition comprising at least one of a restricted lane, a restricted zone, a construction zone, and accident area, an incline, a hazardous road surface. The computer is further configured to determine at least one autonomous action based on the condition, the at least one autonomous action including at least one of altering a speed of the vehicle, controlling vehicle steering, controlling vehicle lighting, transitioning the vehicle to manual control, and controlling a distance of the vehicle from an object.

Abstract: In one embodiment of the disclosed subject matter, a trailer backup assist system includes a state estimator that determines a current position of a trailer relative to a waypoint position. In addition, the trailer backup assist system includes a trajectory planner that generates first and second circular trajectories tangent to one another spanning between the current and waypoint positions. The trailer backup assist system also includes a controller that reverses the trailer to the waypoint position along the first and second circular trajectories, which are dynamically regenerated as the trailer reverses along the first circular trajectory.

Abstract: A backup assist system for a vehicle reversing a trailer includes a brake module and a throttle module. The system further includes a controller having a vehicle speed detector and coupled with the brake module and the throttle module for implementing a backup mode including detecting an adverse operating condition and then adjusting at least one of the brake module and the throttle module and terminating the backup mode upon detecting the adverse operating condition for a time interval.

Abstract: An autonomous control system for a vehicle that controls the speed and steering system of the vehicle to operate in a lane-keeping mode or a lane-changing mode. Position sensors sense the location of surrounding vehicles. A lane determining system identifies a current lane where the vehicle is located. A source of oncoming lane course data provides information as to the course of the current lane. A controller provides instructions to the steering system and speed control system to maneuver the vehicle in either the lane-keeping mode or the lane-changing mode. The driver may override the control system by providing a manual input to the steering system or the speed control system.

Abstract: A vehicle system includes a sensor that detects a speed of at least one nearby vehicle and outputs a speed signal representing the speed of the at least one nearby vehicle. The vehicle system further includes a processing device programmed to determine a set point speed based on the speed signal output by the sensor. The processing device generates a command signal to control a host vehicle in accordance with the set point speed.

Abstract: An intersection of a host vehicle and a target vehicle is identified. Data relating to the target vehicle are collected. A map of a surrounding environment is developed. A driver intent probability is determined based at least in part on the map. A threat estimation is determined based at least in part on the driver intent probability. At least one of a plurality of safety systems is activated based at least in part on the threat estimation.

Abstract: A display system for a vehicle and trailer is disclosed. The system comprises an interface configured to receive a directional input and a controller in communication with the interface and a screen. The controller is operable to receive a hitch angle and determine a heading direction of the trailer. The controller is further operable to determine a predicted heading of the vehicle aligned with the trailer based on the hitch angle. The predicted heading of the trailer is then displayed by the controller on the screen.

Abstract: A computer in a first vehicle is configured to receive data relating to a second vehicle.
