摘要： A method of guiding a vehicle to a region for initiating a parallel parking maneuver. A region of feasible starting locations for successfully performing a parallel parking maneuver is determined by a processor. A position of the vehicle relative to the region of feasible starting locations is determined. A determination is made whether the vehicle is in a zero heading position. The vehicle is guided along an initial target path by controlling a steering actuator until the vehicle is in a zero heading position relative to the road of travel in response to the vehicle is not in the zero heading position. A planned path is generated that includes two arc-shaped trajectories extending between the vehicle at the zero heading position and a position within the region of feasible starting locations as determined by the processor. The steering actuator is controlled to follow the planned path to the feasible region.

摘要： A method of determining functionality of a vision-based imaging system for a vehicle includes capturing images by the vision-based imaging system. The images include landmarks that are identified in multiple images for distinguishing displacement of landmarks between the images. Edge maps for each of the images are generated. Like regions of at least two edge maps are compared for distinguishing displacement of a landmark between the at least two edge maps. Each pixel location of a first edge map is compared with a same pixel location of a second edge map for determining whether each compared pixel location has a different intensity value. An aggregate number of pixel locations having a different intensity value between the at least two edge maps is determined and compared to a threshold. An error message is generated in response to the aggregate number being less than the threshold.

摘要： A lane tracking system for a vehicle includes a front steering controller, a rear steering controller, and a lane tracking processor. The front steering controller is configured to rotate a front wheel of the vehicle through a front steering angle in response to a front steering torque command, and the rear steering controller is configured to rotate a rear wheel of the vehicle through a rear steering angle in response to a rear steering torque command. The lane tracking processor is configured to determine a desired course of the vehicle along a roadway, estimate a trajectory of the vehicle based on sensed vehicle motion, compute an error between the determined desired course and the estimated trajectory, and provide a front steering torque command to the front steering controller, and a rear steering torque command to the rear steering controller to minimize the computed error.

摘要： A vehicle merge control system includes a host communication system in a host vehicle for exchanging vehicle position and kinematics data with a remote communication system in at least one remote vehicle. A vehicle host processor determines respective positions and paths of travel of the at least one remote vehicle and the host vehicle. The host processor determines a time to intersect based on the positions and predicted paths of travel between the host vehicle and remote vehicle during a merging maneuver. A host vehicle is configured to transmit a host vehicle intention message from the host communication system to the remote communication system for negotiating a merging position between the host vehicle and the at least one remote vehicle. The host vehicle executes the merging maneuver using the negotiated merging position.

摘要： Vehicle steering measurements of a vehicle may be measured. Expected vehicle steering measurements may be calculated, each calculated expected vehicle steering measurement corresponding to one of the measured vehicle steering measurements. At least one difference between one of the measured vehicle steering measurements and its corresponding calculated expected vehicle steering measurement may be calculated. A lower boundary and an upper boundary of at least one override transition zone, each of the override transition zones corresponding to one of the measured vehicle steering measurements and its corresponding calculated expected vehicle steering measurement, may be calculated. Steering control of the vehicle may be gradually transferred from an automatic vehicle control system to a driver of the vehicle over a predetermined period of time when one or more of the calculated differences lie between the calculated lower boundary and the calculated upper boundary of the corresponding override transition zone.

摘要： A system and method for determining whether a vehicle driver is holding a steering wheel of the vehicle while the vehicle is in an autonomous driving mode. The vehicle will include an electric power steering (EPS) system and may include an active front steering (AFS) system, both of which include a motor that can apply a high frequency and low amplitude perturbation signal to the steering wheel of the vehicle that is not felt by the vehicle driver and does not cause the vehicle to turn, but is able to be detected by a steering angle sensor. The method subtracts a steering angle command signal from the steering angle signal and removes road disturbances, and then determines whether the induced perturbation signal is present in the steering angle sensor signal. If the perturbation signal is present, then the system knows that the vehicle driver is not holding the steering wheel.
