The Effect of Power Steering on Idle Control of EMS Systems

Feng Huashuai，Lu Yingjie，Mai Weiping，Lian Dianjiao，Ye Caisheng

Abstract：The power steering signal is sent to the EMS （Engine Model System） through the CAN bus signal as a condition for triggering the EMS control system to intervene in torque compensation， and the dynamic static torque compensation loading method proposed in this paper can effectively solve the phenomenon of speed bulging pits caused by sudden load in target speed control.

Key words：EMS control system， idle control， target idling， torque compensation， PID teach-in， EPS load flag

EMS發(fā)動(dòng)機(jī)控制系統(tǒng)能夠在怠速工況實(shí)現(xiàn)目標(biāo)轉(zhuǎn)速的平穩(wěn)控制，完全暖機(jī)后目標(biāo)怠速一般設(shè)定在750±50rpm，開啟空調(diào)后則會(huì)相應(yīng)的提高到800±50rpm，防止未知負(fù)載如突然打開大燈、轉(zhuǎn)動(dòng)方向盤、開啟雨刮負(fù)載等突然的施加造成發(fā)動(dòng)機(jī)熄火，引起售后市場(chǎng)問題。（剩余3495字）
