Abstract: A method of transitioning from an autonomous driving mode to a manual driving mode for a vehicle is provided. The method includes comparing a steering device input angle to an autonomously controlled steering angle to determine a steering angle error. The method also includes comparing an acceleration or deceleration input to an autonomously controlled acceleration or deceleration input to determine an acceleration or deceleration error. The method further includes progressively transitioning to the manual driving mode in a weighted manner based on a confidence level factor determined by a calculation that factors in the steering angle error and the acceleration or deceleration error.

Abstract: A method of assembling a rolling element intermediate shaft assembly includes providing a solid shaft, a tubular shaft, and a wear plate. The solid shaft includes first and second ends. A tubular shaft includes an inner wall with an axially extending groove formed therein. The groove includes an inner surface. The wear plate includes a bottom surface that defines an axially extending channel. The wear plate is orientated in the groove of the tubular shaft with a gap defined by the wear plate and the groove of the tubular shaft. The solid shaft is then inserted into the tubular shaft. At least one ball bearing is inserted within the channel between the wear plate and the solid shaft.

Abstract: A method for steering control for a marine vessel includes determining a first position of a hand wheel of the marine vessel. The method also includes determining, after a first period, a second position of the hand wheel. The method also includes determining a difference between the first position of the hand wheel and the second position of the hand wheel. The method also includes, in response to a determination that the difference between the first position of the hand wheel and the second position of the hand wheel is less than a threshold: capturing a first heading of the marine vessel; and selectively controlling steering of the marine vessel according to the first heading.
