Abstract (en)

[origin: WO2006106058A1] An internal combustion engine has an exhaust-gas turbocharger which comprises an exhaust-gas turbocharger actuator. Furthermore, it has an exhaust-gas recirculation device which comprises an exhaust-gas recirculation valve. An apparatus for controlling the internal combustion engine comprises an exhaust-gas turbocharger regulator which, as a function of the setpoint boost pressure (BP_SP) and an actual boost pressure (BP_AV), determines a controlled actuating-variable exhaust-gas back-pressure (FB_SG_PEXH). An exhaust-gas recirculation regulator is provided which, as a function of a setpoint air mass flow (MAF_SP) and an actual air mass flow (MAF_AV), determines a controlled actuating-variable exhaust-gas recirculation mass flow (FB_SG_EGR). A first decoupling unit is configured to determine a decoupling mass flow (MF_DEC) in an exhaust-gas section upstream of a branch of the exhaust-gas recirculation device, to be precise as a function of the pilot-control actuating-variable exhaust-gas recirculation mass flow (PRE_SG_EGR) and the controlled actuating-variable exhaust-gas recirculation mass flow (FB_SG_EGR) . A second decoupling unit is provided which determines a decoupling exhaust-gas back-pressure (PEXH_DEC), to be precise as a function of the pilot-control actuating-variable exhaust-gas back-pressure (PRE_SG_PEXH) and the controlled actuating-variable ehaust-gas back-pressure (FB_SG_PEXH) . A first conversion unit is configured to determine an actuating signal (ATL_S_SIG) for the exhaust-gas turbocharger actuator as a function of the pilot-control actuating-variable exhaust-gas back-pressure (PRE_SG_PEXH), the controlled actuating-variable exhaust-gas back-pressure (FB_SG_PEXH) and the decoupling mass flow (MF_DEC). A second conversion unit is provided which determines an actuating signal (S_SIG_EGR) for the exhaust-gas recirculation valve as a function of the pilot-control actuating-variable exhaust-gas recirculation mass flow (PRE_SG_EGR), the controlled actuating-variable exhaust-gas recirculation mass flow (FB_SG_EGR) and the decoupling exhaust-gas back-pressure (PEXH_DEC).
