  • Patent number: 11598870
    Abstract: In various embodiments, methods, systems, and vehicle apparatuses are provided. A method for estimating a Hitch Articulation Angle (HAA) using Ultra-Sonic Sensors (USSs) while ensuring quality detected echo signal performance using plausibility filtering, generating at least one set of USS data based on detecting a set of echo signals generated by a plurality of USSs configured about a vehicle coupled to a trailer; determining based on a set of USS data using a selected set of geometric equations in a plausibility filtering process for an arbitrary frontal shape of the trailer; and generating at least one comparison based on at least one set of USS data estimations to a kinematic model at low speeds for ensuring that results of the kinematic model to the HAA associated with the determined trailer shape is based on a pair of detected echo signals that are deemed to have a higher signal performance.

  • Patent number: 10800412
    Abstract: An automotive vehicle includes at least one actuator configured to control vehicle steering, at least one sensor configured to detect a profile of a driving surface proximate the vehicle, and at least one controller in communication with the actuator and the sensor. The controller is configured to identify a plurality of potential paths within a driveable lane, determine at least one road profile parameter for each respective potential path, identify a desired path based on a comparison of the respective road profile parameters for the plurality of potential paths, and control the actuator to steer the vehicle according to the desired path.
