  • Patent number: 11117612
    Abstract: Technical solutions are described for attenuating dither noise in a steering system. An example method includes computing multiple filter parameters, each filter parameter based on a corresponding signal in the steering system. The method further includes determining at least one final filter parameter from the plurality of filter parameters by arbitrating the plurality of filter parameters. The method further includes dynamically configuring a filter using the at least one final filter parameter. Further, the method includes filtering a motor torque command using the filter, a filtered motor torque command being applied to a motor to generate a corresponding amount of torque.

  • Patent number: 10538269
    Abstract: Technical solutions are described for estimating handwheel angle of a steering wheel of a vehicle based on road wheel rotational speed data. In one or more examples, the technical solutions are used when the vehicle does not have a sensor to measure the handwheel angle, or if the handwheel angle sensor is faulted and unable to provide data on the actual handwheel angle.

  • Patent number: 5645024
    Abstract: A timing chain cover which is mounted to an engine block having an opening in general axial alignment with an exposed end of a camshaft. A cap is mounted to the cover and generally seated in the opening. The cap includes a hole in general axial alignment with the camshaft and an adjustable button is secured in the hole. One end of the button engages the camshaft to prevent cam walk and opposed end is accessible for adjustment without removal of the cover from the engine block.
