用于配备有增压器的内燃机的控制系统和控制方法
Abstract:
一种用于配备有增压器的内燃机的控制系统，其利用具有虚拟上游进气压力(PA)的虚拟内燃机模型、根据加速器踏板行程(θA)来计算目标进气质量流量(mt’)。而后，此控制系统根据测得的上游进气压力(PIN)计算目标节气门开度(θ)，由此提供所述目标进气质量流量(mt’)，并基于所述目标节气门开度(θ)控制节气门。
Abstract(English):

A control system for an internal combustion engine equipped with a supercharger calculates a target intake mass airflow (mt') in accordance with an accelerator pedal travel (thetaA), using a virtual internal combustion engine model having a virtual upstream intake air pressure (PA). The control system then calculates a target throttle opening (thet) in accordance with a measured upstream intake pressure (PIN) so as to provide the target intake mass airflow (mt'), and controls a throttle valve based on the target throttle opening (theta).
