Abstract
Methods and systems are provided for adjusting an EGR valve and one or more intake throttles responsive to the output of an intake oxygen sensor to provide a desired amount of EGR flow while maintaining engine torque. The adjustments are coordinated to improve distributed control of the EGR valves and intake throttles, and enable EGR flow even when one actuator is limited.
