  • Patent number: 11661082
    Abstract: A control system of the autonomous vehicle may generate multiple possible behavior control movements based on the driving goal and the assessment of the vehicle environment. In doing so, the method and system selects one of the best behavior control, among the multiple possible movements, and the selection is based on the quantitative grading of its driving behavior.

  • Patent number: 11660979
    Abstract: A method and system for estimating state of charge of a lithium battery cell of a vehicle is provided. The method comprises providing a non-linear function of the lithium battery cell, a normalized lithium surface density and an actual voltage at a current of the lithium battery cell having an internal resistance. The method further comprises determining an actual lithium surface density based on the actual voltage relative to an inverse of the non-linear function. The method further comprises determining a varying parameter based on the actual lithium surface density relative to a first diffusion model. The method further comprises determining a predicted lithium surface density based on the varying parameter relative to a second diffusion model. The method further comprises determining an estimated state of charge of the lithium battery cell when a difference between the predicted and actual lithium surface densities is less than a first threshold.

  • Patent number: 11663836
    Abstract: A system and method for error estimation in an eye gaze tracking system in a vehicle may include an operator monitoring system providing measured eye gaze information corresponding to an object outside the vehicle and an external object monitoring system providing theoretical eye gaze information and an error in the measured eye gaze information based upon the measured eye gaze information and the theoretical eye gaze information.

  • Patent number: 11661109
    Abstract: A method increases fidelity of a lane localization function aboard a motor vehicle by receiving input signals indicative of a relative position of the vehicle with respect to a roadway. The input signals include GPS and geocoded mapping data, and an electronic turn signal indicative of activation of the turn signal lever. Sensor-specific lane probability distributions are calculated via the lane localization function using the input signals. The various distributions are fused via the localization function to generate a host lane assignment. The host lane assignment corresponds to a lane of the roadway having a highest probability among a set of possible lane assignments. An autonomous steering control action is performed aboard the motor vehicle using an Advanced Driver Assistance System (ADAS) in response to the host lane assignment. A motor vehicle has a controller that performs the method, e.g., by executing instructions from computer-readable media.
