Abstract: A trailer backup assist system, according to one embodiment, provides a sensor that senses a hitch angle between a trailer and a vehicle. The trailer backup assist system also provides a selection device for selecting a longitudinal direction of the trailer or the vehicle in a static orientation. Further, the trailer backup assist system provides a controller that generates a steering command to the vehicle when reversing based on the hitch angle to guide the trailer in the selected longitudinal direction. The controller determines a kinematic relationship of the trailer and the vehicle based on a length of the trailer and a wheelbase of the vehicle, whereby the steering command is generated based on the kinematic relationship.

Abstract: A vehicle is operated at least partially autonomously. A predicted path of the vehicle is monitored to identify an object with which the vehicle is likely to collide. A graphical user interface (GUI) is provided that includes the predicted path, a proposed path for the vehicle to avoid a collision with an object, and the vehicle. A selection is made to follow one of the predicted path and the proposed path. The GUI is updated to include the selected one of the predicted path and the proposed path, along with a location of the vehicle on the selected one of the predicted path and the proposed path.

Abstract: A vehicle includes a sensor configured to detect a first road feature, an adjustable suspension system, and a processing device. The processing device is configured to determine, using a drive history map, a location of the vehicle based on the first road feature and apply a suspension profile to the suspension system. The suspension profile is associated with a second road feature identified by the drive history map, which is at a different location from the first road feature.

Abstract: A vehicle sub-system controller is configured to receive a first message and a second message, wherein the first message includes at least a command for the controller, and the second message includes at least a target value for the controller to achieve. A fault may be detected with respect to the first message; and an adjustment to the sub-system may be locally determined in the sub-system controller to achieve the target value.

Abstract: A trailer back-up assist apparatus comprises an obstacle sensing system operable to output information characterizing proximity of a object adjacent to a vehicle-trailer combination while the vehicle-trailer combination is being backed toward a targeted location and a trailer back-up assist system correction apparatus coupled to the obstacle sensing system. The trailer back-up assist system uses the information characterizing proximity of the object to determine if a path of the vehicle-trailer combination needs to be altered to limit a potential of the vehicle-trailer combination colliding with the object and implements a path correction action to alter the path of travel of the vehicle-trailer combination to reduce the potential for the vehicle-trailer combination colliding with the object.

Abstract: Vehicle operating systems are autonomously operated. A transient in an upcoming path of the vehicle is determined from a comparison of vehicle path data and vehicle status data to a threshold of mechanism first operating system. Operational parameters for one of first and second operating systems are selected according to the comparison. The selected operational parameters are applied to the operation of the one of the first and second operating systems.

Abstract: A vehicle comprises a communication interface for enabling information to be communicated to a and from an occupant of the vehicle and a trailer back-up assist system coupled to the communication interface. The trailer back-up assist system is operable for determining a selected width of a lane within which the vehicle and an attached trailer are to be backed from a current position of the vehicle to reach a targeted location for the attached trailer and for outputting to the occupant of the vehicle via the communication interface information characterizing an ability of the vehicle to be backed within the lane from the current position of the vehicle.

Abstract: Data is collected during operation of a vehicle. A determination is made that a confidence assessment of at least one of the data indicates at least one fault condition. A first autonomous operation affected by the fault condition is discontinued, where a second autonomous operation that is unaffected by the fault condition is continued.

Abstract: A vehicle operator is identified. Based at least in part on the operator's identity, one or more parameters are determined specifying a mode for autonomously operating the vehicle. The vehicle is autonomously operated at least in part according to the one or more parameters.

Abstract: A system and method of calculating a heading angle for a trailer that is being backed by a vehicle. A trailer backup assist control module, in communication with a hitch angle detecting apparatus, receives a hitch angle and determines displacement of left and right vehicle wheels using information supplied by vehicle wheel speed sensors while the vehicle is backing the trailer. A vehicle heading angle is determined using left and right wheel displacement information and a known vehicle track width. A trailer heading angle is then calculated using the vehicle heading angle and the hitch angle.

Abstract: A trailer backup steering input apparatus is coupled to a vehicle. The trailer backup steering input apparatus comprises a rotatable control element (e.g., a knob) and a rotatable control element movement sensing device. The rotatable control element biased to an at-rest position between opposing rotational ranges of motion. The rotatable control element movement sensing device is coupled to the rotatable control element for sensing movement of the rotatable control element. The rotatable control element movement sensing device outputs a signal generated as a function of an amount of rotation of the rotatable control element with respect to the at-rest position, a rate movement of the rotatable control element, and/or a direction of movement of the rotatable control element with respect to the at-rest position.

When incorrect trailer measurements have been entered, the trailer backup assist system recognizes the error, initiates a warning and requests corrective action to correct the trailer measurements. Default values for a maximum controllable curvature limit and a maximum controllable angle replace the limits calculated and applied by the calibration model that used incorrect trailer measurements, until corrected trailer measurements may be entered by the driver.
