Patent number: 9598102Abstract: A method of mitigating abnormalities in a first control command for controlling a power steering system is provided. The method generates a range signal indicative of a range of command values based on a plurality of input signals. The method determines whether the first control command is out of the range for longer than a predetermined duration of time. The method limits the first control command to the range and sends the limited first control command to the power steering system in response to determining that the first control command is out of the range for shorter than or equal to the duration of time.Type: GrantFiled: October 20, 2014Date of Patent: March 21, 2017Assignees: STEERING SOLUTIONS IP HOLDING CORPORATION, BAYERISCHE MOTORENWERKE AKTIENGESELLSCHAFTInventors: Scott A.

Patent number: 8560178Abstract: A system for providing steering torque assistance to an electrically-powered steering apparatus comprises a torque assistance motor coupled to the steering apparatus. A steering controller is configured to cause the torque assistance motor to apply a commanded level of steering torque assistance to the steering apparatus. The steering controller is configured to determine the commanded level of steering torque assistance based on a product of a scheduled level of steering torque assistance and a torque assistance scale factor, wherein the scheduled level of steering torque assistance is determined from a scheduled torque assistance characteristic having a nominal assist. The steering controller is configured to determine a scaled assist based on feedback from one or more safety sensors; and the torque assistance scale factor is determined as a ratio of the scaled assist and the nominal assist.Type: GrantFiled: November 30, 2011Date of Patent: October 15, 2013Assignee: Steering Solutions IP Holding CorporationInventor: Kevin L. Derry

Patent number: 7475907Abstract: The present invention provides an apparatus and method for pivoting and locking a steering column. The apparatus of the invention includes a steering column extending axially between first and second ends. The steering column is pivotally mountable to a vehicle at the second end. The apparatus also includes a locking mechanism spaced from the second end. The locking mechanism is operative to releasibly secure the steering column in a selected position of adjustment. The apparatus also includes a spring urging the steering column in a first pivoting direction. The spring is disposed in axially spaced relation adjacent to said locking mechanism. The method of the invention includes the step of pivotally mounting a steering column that extends axially between first and second ends to a vehicle. The method also includes the step of releasibly securing the steering column in a selected position of adjustment with a locking mechanism that is spaced from the second end.Type: GrantFiled: August 10, 2004Date of Patent: January 13, 2009Assignee: Delphi Technologies, Inc.Inventors: Lee Tinnin, Kevin L.

A plurality of helical or spiral shaped threshing groups are attached to the outer peripheral surface and extend substantially the length of the drum. Each of the curved threshing members making up a helical group are placed end to end resulting in a continuous and uninterrupted spiral or helical pattern. A plurality of straight threshing members are attached to the outer peripheral of the drum. The straight threshing members are interspersed between the helical or spiral groups in a plurality of longitudinally extending rows. The rows may be arranged in alternating fashion resulting in a staggered appearance.Type: GrantFiled: September 25, 1997Date of Patent: July 6, 1999Assignee: Derry Farms, Inc.Inventor: Kevin L. Derry
