    摘要: One embodiment of the invention may include a method of controlling exhaust gas recirculation (EGR) in a turbocharged compression-ignition engine system including a high pressure (HP) EGR path and a low pressure (LP) EGR path. The method may include determining a target total EGR fraction for compliance with exhaust emissions criteria, and determining a target HP/LP EGR ratio to optimize other engine system criteria within the constraints of the determined target total EGR fraction. The determining of the target HP/LP EGR ratio may include using at least engine speed and load as input to a base model to output a base EGR value, using at least one other engine system parameter as input to at least one adjustment model to output at least one EGR adjustment value, and adjusting the base EGR value with the at least one EGR adjustment value to generate at least one adjusted EGR value.
