  • Publication number: 20240140449
    Abstract: A system for planning motion of a vehicle includes a controller having a processor and tangible, non-transitory memory on which instructions are recorded. The vehicle is capable of an automated driving operation. A planning module is executable by the controller to generate a vehicle trajectory constrained by a set of planning parameters. During a degraded driving situation, an adjustment module is executable by the controller to generate at least one adjusted parameter in the set of planning parameters. The controller is adapted to register occurrence of the degraded driving situation when the planning module is unable to generate a feasible path for the vehicle constrained by the set of planning parameters. The planning module is adapted to generate a modified trajectory plan based on the at least one adjusted parameter, with the automated driving operation being based on the modified trajectory plan during the degraded driving situation.

  • Patent number: 11970063
    Abstract: Examples described herein provide a computer-implemented method that includes calculating, by a processing device, a motor acceleration error based at least in part on a motor torque and a motor speed. The method further includes calculating, by the processing device, a regression fit line based at least in part on the motor acceleration error. The method further includes identifying, by the processing device, a zero point using the regression fit line. The method further includes comparing, by the processing device, the zero point to a datum reference to determine a difference. The method further includes integrating, by the processing device, the difference to determine the lash angle. The method further includes controlling, by the processing device, the motor based at least in part on the lash angle.
