摘要： Disclosed herein is an apparatus that relates to a gear set. The apparatus includes, a housing, a first gear movable in the housing such that a first axis defined by the first gear is repositionable relative to the housing, a second gear in mesh with the first gear, and a second axis defined by the second gear. The apparatus constrains movement of the first axis to a plane containing both the first axis and a line commonly perpendicular to the first axis and the second axis, and a biasing member that urges the first gear toward the second gear.

摘要： A method for controlling a four-wheel steering system of a vehicle includes recognizing a driver-selectable mode, receiving a signal preferably indicative of a front wheel steering-angle, and determining a rear-to-front steering-angle ratio in correspondence with the recognized mode and the received signal; and optionally includes receiving a signal indicative of vehicle speed, recognizing a current system state, determining a desired steering-angle, generating a command based on the desired and received steering-angles and the recognized system state, and diagnosing conditions in accordance with the received signals in order to enter a output disable mode.

摘要： A system and a method for controlling a steering position of at least one rear wheel of a vehicle are provided. The vehicle has both a brushless electric motor with a plurality of electrical phase windings and a steering actuator. The brushless electric motor has a rotor configured to drive the steering actuator. The steering actuator is operably coupled to at least one rear vehicle wheel. The method includes determining a desired voltage value indicative of about one-half of a peak-to-peak voltage to be applied to each of the plurality of electrical phase windings of the brushless electric motor based on a desired rear vehicle wheel steering angle and a measured rear vehicle wheel steering angle. The method further includes determining when the desired voltage value is greater than a threshold voltage level. The method further includes calculating a phase advance angle based on at least the desired voltage value and the threshold voltage level. The method further includes phase advancing a plurality of voltage waveforms applied to the plurality of electrical phase windings, wherein each phase advanced voltage waveform is phase advanced an amount substantially equal to the phase advance angle, wherein phase advancing the voltage waveforms increases a speed of the rotor at a desired torque to thereby increase a speed at which the steering actuator moves at least one rear vehicle wheel toward the desired rear vehicle wheel steering angle.
