Abstract
Methods and systems are provided for coordinating operation of a high pressure EGR control loop with a boost pressure control loop. In one example, following a tip-in, turbine vane position may be adjusted as a function of a maximum permissible exhaust pressure upstream of a turbocharger turbine. The maximum permissible exhaust pressure may be determined as a function of a HP EGR valve position at the time of the tip-in.
