Method and apparatus for compensating steering pull |
摘要 |
<p>A method, system, and apparatus for providing enhanced steering pull compensation are provided. The method compensates for steering pull in a vehicle steering system that includes a handwheel. The method includes monitoring the vehicle to determine whether the vehicle is heading forward along a substantially linear straight-ahead path and, if so, measuring handwheel torque, as a sensed torque signal, to determine an amount of steering pull existing at the handwheel. The method also includes generating a torque assist signal in response to the sensed torque signal and calculating an offset signal for reducing the amount of steering pull to substantially zero. The method further includes producing a modified torque assist signal by adding the offset signal to the torque assist signal, and applying the modified torque assist signal to the vehicle steering system.</p> |
