Abstract: A method for optimizing vehicle steer-by-wire characteristics, includes collecting steer-by-wire steering system data for multiple predetermined data segments. Multiple driving quality objective indices are determined for each segment. A trend line is prepared based on the multiple predetermined data segments using a first algorithm, a second algorithm and a third algorithm, each assigned to one of the driving quality objective indices. Values obtained from the first algorithm, the second algorithm and the third algorithm are superimposed to create a net desired incremental change in damping, steering ratio and base assist. A steering calibration modification command is generated in real-time using the incremental change in damping, steering ratio and base assist.

Abstract: A method to determine a fatigue limit for a material. Form a test component including the material. Identify a resonant frequency of the component and an excitation frequency which causes the component to vibrate. Measure a response parameter of the component when excited at the excitation frequency. Test the component to determine its fatigue limit by sub-steps to: apply an excitation force to the component at the excitation frequency to cause vibration of the component; alter the applied excitation force at constant excitation frequency to maintain the response parameter constant; measure at least one of an input parameter and an output parameter; iterate the sub-steps to alter and measure until the first order, second order, or first and second order derivatives of the input parameter and/or output parameter exhibit a discontinuity. Repeat the steps for a different excitation frequency. The fatigue limit for the material includes all the identified discontinuities.

Abstract: One example of a wellbore control tool and a method of use is described. A leak is detected in a cased wellbore comprising a multiple telescoping casing sections. A fluid flows in an uphole direction through the cased wellbore. A flow of the fluid in the uphole direction results in a first force in the uphole direction.

The open downhole end of the wellbore tool provides metal to metal contact against the uphole end of the second telescoping casing section and restricts fluid flow into the leak.
