Abstract
Methods and systems are provided for improving engine torque response during transient condition. In one example, a method may include adjusting intake throttle and exhaust waste-gate valve based on the operator torque demand and concurrently, scheduling exhaust gas recirculation (EGR) and variable cam timing (VCT) based on a predicted torque shortfall ratio. The scheduling of EGR and VCT is independent of the actual position of intake throttle and exhaust waste-gate valve.
