METHOD FOR IDLE SPEED CONTROL |
摘要 |
A method is disclosed for controlling engine output in a vehicle having a hydraulic power steering system. The method may include, during an idle condition where an engine speed is set to an idle speed, adjusting engine output based on a learned absolute steering wheel angle to compensate for changes in engine load caused by operation of the hydraulic power steering system. The learned absolute steering wheel angle may be based on a steering wheel angle relative to a steering wheel position at vehicle startup and operating conditions from previous vehicle operation before the vehicle startup.
