Abstract:
A control system for a recirculation valve of a turbocharger includes a target boost module, a close request module, and a close delay module. The target boost module determines a target boost for the turbocharger based on a torque request. The close request module selectively generates a close request to close the recirculation valve based on the target boost. The close delay module, in response to the generation of the close request, delays closing of the recirculation valve.
