FOUR-WHEEL STEERING MATCHING PROCESS

摘要

PROBLEM TO BE SOLVED: To provide a method for matching the position sensor of a wheel 12 with steerable wheels 28 and 44. SOLUTION: This four-wheel steering matching process comprises a step for providing the absolute value of a position according to a position signal 66 from a steering wheel position sensor 56, a step for providing the relative value of the position according to the calculated values of encoder signals 70a and 70b from a position encoder 50, and a step for providing the index value of the position according to an index signal 72. The process further comprises a step for receiving a mathchable signal and a step for determining a correction factor according to the relative value of the position and the index value of the position.
