Abstract: Methods and motor vehicles that assist a driver are provided. In an exemplary embodiment, a method includes identifying one or more potential parking positions for a motor vehicle. Selection of a desired parking position is requested, and a suggested driving path for positioning the motor vehicle in the desired parking position is calculated. The suggested driving path is displayed to the driver on a display screen, and the suggested driving path is re-calculated as the driver drives the motor vehicle with a steering wheel. The display screen is updated with the suggested driving path after the suggested driving path is re-calculated and as the driver drives the motor vehicle with the steering wheel.

Abstract: Methods and systems are provided for detecting faults in a sensor and reconstructing an output signal without use of the faulty sensor. In one embodiment, a method includes: receiving, by a processor, sensor data indicating a measured value from a first sensor; receiving, by a processor, sensor data indicating measured values from a plurality of other sensors; computing, by a processor, virtual values based on a vehicle model and the sensor data from the plurality of other sensors; computing, by a processor, a residual difference between the measured value from the first sensor and the virtual values; detecting, by a processor, whether a fault exists in the first sensor based on the residual difference; and when a fault in the sensor is detected, generating, by a processor, a control value based on the virtual values instead of the measured value.

Abstract: A method for providing vehicle lateral steering control. The method includes providing a mathematical model of vehicle dynamics that includes a state variable, a steering control variable and a future road disturbance factor that defines the upcoming road curvature, banks and slopes of the roadway. The method determines an optimal steering control signal that includes a feedback portion and a feed-forward portion, where the feed-forward portion includes the road disturbance factor. The method determines a state variable and a control variable for the current roadway curvature, bank and slope for stationary motion of the vehicle for constant speed, yaw rate and lateral velocity. The method then introduces a new state variable and control variable for dynamic vehicle motion for variable speed, yaw rate and lateral velocity that is a difference between the state and control variables for predicted future times and the steady state variables.

Abstract: A method for determining a snow covered surface condition of a path of travel. A beam of light is emitted at a surface of the path of travel by a light emitting source. An image of a path of travel surface is captured by an image capture device. The image capture device is mounted on the vehicle and captures an image in a downward direction. The captured image captures the beam of light emitted on the path of travel surface. Analyzing a subsurface scattering of the light generated on the path of travel surface by a processor. A determination is made whether snow is present on the path of travel. A snow covered path of travel surface signal is generated in response to the identification of snow on the path of travel.

Abstract: A method for providing vehicle steering control through a curve in an autonomously driven or semi-autonomously driven vehicle that is towing a trailer. The method determines that the trailer will cross out of the travel lane based on the curvature of the curve and the turn radius of the trailer. The method calculates a start turn radius of the vehicle for a start location of the curve, an end turn radius of the vehicle for an end location of the curve, and a turn end point proximate the end location or a turn start point proximate the start location. The method provides initial and boundary conditions for determining a desired path of the vehicle through the curve that prevents the trailer from crossing out of the lane and determines the desired path based on the initial and boundary conditions by solving a polynomial equation.

Abstract: A rear cross traffic avoidance system includes an object detection device sensing remote objects rearward of a host vehicle. An object classifier distinguishes a remote dynamic object from remote static objects. The object classifier identifies a shape of the dynamic object. A tracking system tracks the remote dynamic object. A processor determines the remote object being on an intersecting path to the remote vehicle. The processor determines a warning threat assessment as a function of a time to intersect between the host vehicle and the remote dynamic object. The processor determines a brake threat assessment in response to an actuated warning of a collision. A brake actuation system actuates a braking operation for mitigating the collision.
