Abstract: A method for providing low speed lateral steering control for an autonomously driven or semi-autonomously driven vehicle includes obtaining a desired final vehicle position relative to a current vehicle position, and calculating, by one or more data processors, a target vehicle position based on the current vehicle position and the desired final vehicle position. The method further includes calculating, by the one or more data processors, a road wheel angle command value based on the target vehicle position; determining, by the one or more data processors, a control signal based on the calculated road wheel command value; and providing the control signal to a steering controller.

Abstract: A vehicle including an advanced driver-assistance system (ADAS) and operator-adjustable devices is described. Controlling the vehicle includes identifying a vehicle operator, and capturing a plurality of operator-selectable settings associated with the plurality of operator-adjustable devices for the vehicle operator. A base profile and a second profile are determined for the vehicle operator based upon the first subset associated with non-autonomous operation of the vehicle and the second subset associated with ADAS, respectively. The plurality of operator-adjustable devices are controlled to the operator-selectable settings associated with the base profile when the vehicle is operating in the non-autonomous mode, and the plurality of operator-adjustable devices are controlled to the operator-selectable settings associated with the second profile when the vehicle is being controlled at least in part by one or more of the subsystems of the ADAS.

Abstract: A system to detect and avoid spilled cargo in an automobile vehicle, includes an automobile vehicle rear cargo area including a floor to temporarily receive a storage item in the cargo area. A lift gate is moved between a closed and latched position and a fully open position inclusive to allow loading and removal of the storage item. A vision system identifies the storage item when initially loaded in the cargo area and identifies if the storage item is initially positioned in a cargo spill position or subsequently moves to the cargo spill position. A cargo stop device is releasably connected to the lift gate. An operating system releasably stores the cargo stop device when the storage item is not in the cargo spill position and deploys the cargo stop device when the storage item is in the cargo spill position.

Abstract: A method and apparatus that determine parking feasibility are provided. The method includes determining a charging pad location based on information received from sensors or the charging pad, generating a path function corresponding to a path from a vehicle position to the charging pad location, determining whether a vehicle is within a parking maneuver feasibility region by comparing values of the generated path function, a minimum turning radius of the vehicle, and a maximum steering angle rate of the vehicle, and moving the vehicle to the charging pad location if the vehicle is in the parking maneuver feasibility region.

Abstract: An automotive vehicle includes a vehicle-based charging unit including a receiving unit configured to receive power from a ground-based charging unit, the receiving unit including a multi-coil receiver, a first actuator operably coupled to the vehicle-based charging unit and configured to adjust a first position of the vehicle-based charging unit relative to the ground-based charging unit, and a controller configured to selectively actuate the first actuator. The controller is configured to receive first performance indicator data indicating a first alignment between the charging units, determine an alignment error between the charging units and calculate a first position adjustment of the vehicle-based charging unit, automatically control the first actuator to implement the first position adjustment of the vehicle-based charging unit, and receive second performance indicator data indicating a second alignment between the charging units, the second alignment resulting in a desired power transfer efficiency between the charging units.

Abstract: A system and method for personalization of security features of a vehicle. The system includes a memory having computer readable instructions and one or more processors for executing the computer readable instructions, the computer readable instructions controlling the one or more processors to perform operations. The operations include detecting a person in a cabin of a vehicle. At least one adjustable vehicle setting is detected in relation to the person in the cabin of the vehicle. The adjustable vehicle setting is compared to a stored adjustable vehicle setting in a first user profile. Operation of the vehicle by the person in the cabin of the vehicle is enabled based on the comparison and a permitted level of access from the first user profile.

Abstract: A method includes obtaining information about a lead vehicle. The lead vehicle is traveling directly ahead of the host vehicle and the information includes velocity of the lead vehicle and a gap g between the host vehicle and the lead vehicle. Based on detecting a change in the velocity of the lead vehicle in the information, a corresponding desired acceleration is computed for the host vehicle using perceived acceleration of the lead vehicle to maintain the gap g within a specified range of gap values. The perceived acceleration of the lead vehicle is based on the change in the velocity indicated by the information. Based on a check of parameters involved in the computing the corresponding desired acceleration, a modified desired acceleration is computed for the host vehicle using a lag for the lead vehicle that results in an intended acceleration of the lead vehicle differing from the perceived acceleration.

Abstract: A vehicle and a system and method of controlling the vehicle. The system includes a sensor and a processor. The sensor obtains a first estimate of a force on a tire of the vehicle based on dynamics of the vehicle. The processor is configured to obtain a second estimate of the force on the tire using a tire model, determine an estimate of a coefficient of friction between the tire and the road from the first estimate of the force and the second estimate of the force, and control the vehicle using the estimate of the coefficient of friction.

Abstract: A tire radius monitoring system for dynamically determining a tire effective radius for each of the wheels on a vehicle is described. The system includes a GPS sensor, a plurality of wheel speed sensors, and a controller. The controller determines, via the GPS sensor, a velocity vector related to longitudinal velocity of the vehicle. The controller determines wheel speeds for the plurality of vehicle wheels, and detects a no-wheel-slip state for the vehicle wheels and the velocity vector from the GPS sensor. The controller determines tire effective radii for the plurality of vehicle wheels based upon the velocity vector for the vehicle and the wheel speeds for the plurality of vehicle wheels during the no-wheel-slip state, and controls vehicle operation based upon the tire effective radii.
