Electronically-controlled throttle system

摘要

To suppress vehicle shock upon acceleration or deceleration, an upper guard value (KGUARD) for throttle rate of change is calculated based on parameters indicative of engine and torque transmission operating conditions. A target throttle sensor voltage change (DVVTA) is calculated based on accelerator depression and compared with the upper guard value KGUARD. If DVTTA>KGUARD, the final target throttle sensor voltage for the present cycle is determined by adding the upper guard value KGUARD to the previously calculated final throttle sensor voltage. If DVVTA
