  • Patent number: 10369988
    Abstract: Method and apparatus are disclosed for autonomous parking of vehicles in perpendicular parking spots. An example vehicle includes a front corner, a camera, and an autonomous vehicle parker. The autonomous vehicle parker is to detect, via the camera, a perpendicular parking spot and an outer boundary of the perpendicular parking spot, determine a linear parking path located within the perpendicular parking spot and based on the outer boundary, and autonomously turn into the perpendicular parking spot such that the front corner travels along the linear parking path.

  • Patent number: 10363874
    Abstract: A hitch assist system and method are provided herein. An imager captures one or more images of a trailer having a hitch coupler. A user-input device is provided for specifying a location of the hitch coupler in the one or more captured images. A controller generates an image patch around the user-specified location, segments the image patch to identify the hitch coupler, and estimates a trailer height based on a height and projective geometry of the imager.

  • Patent number: 10315481
    Abstract: Systems and method for assigning vehicle suspension dynamics are disclosed. Control signals that correspond to a current driving dynamic of a suspension system of a vehicle are generated. A vehicle state associated with the generated control signals is computed and a non-traditional suspension mode is selected.

  • Publication number: 20190071088
    Abstract: A trailer backup assist system is provided herein. The system includes a calibration feature for calibrating an imaging device used for hitch angle detection. The system also employs multiple hitch angle detection methods, a number of which may run in parallel to increase the intervals at which a hitch angle can be measured. The system additionally includes a predictive feature in which a hitch angle can be predicted in instances where a trailer sensing device fails. The system is further configured to estimate a trailer length and generate steering commands that are invariant to the estimated trailer length under certain conditions.

  • Patent number: 10166980
    Abstract: A vehicle having a drivetrain is controlled based on a difference between a torque transmitted by the drivetrain when the vehicle has constant non-zero speed and the torque transmitted by the drivetrain when the vehicle is accelerating. The drivetrain torque may be measured by a drivetrain torque sensor. The effective vehicle mass is computed from the torque difference. The computed mass of the vehicle is used to adjust the activation of a collision warning system or a collision avoidance system. A method of operating a vehicle where the activation of a collision avoidance system is adjusted based on a difference between a torque transmitted by a drivetrain when the vehicle has constant non-zero speed and the torque transmitted by the drivetrain when the vehicle is accelerating is disclosed. The torque difference is used to compute a vehicle mass that is used to adjust a collision warning distance.

  • Patent number: 10000103
    Abstract: A method of controlling a vehicle active suspension system may include, in response to an object being detected forward of the vehicle and a vehicle speed exceeding a threshold, identifying an object classification associated with the object. The method may further include actuating the active suspension system to induce a vibration signature in the vehicle based on the object classification such that a different identified object classification corresponds to a different vibration signature.

  • Patent number: 9945300
    Abstract: A method of operating a vehicle includes measuring a transmission output torque, measuring impeller and turbine speeds, estimating a transmission component torque, and adjusting an engine torque to avoid overstressing a transmission component such as a gear. The method does not rely on an accurate estimate of engine torque. Furthermore, the method does not rely on a fixed transmission torque rating in each gear ratio.
