Abstract:
Methods and systems are provided for improving surge control in a boosted engine system configured with an electric motor to provide electrical boost assistance. Tip-in and tip-out surge are addressed by increasing the opening of a compressor recirculation valve and coordinating the recirculation valve opening with adjustments to an exhaust waste-gate position and a power output by the electric motor. The adjustments enable an intake airflow to be provided that operates the compressor outside a surge region while providing a target boost pressure as operator torque demand increases or decreases.

Claim (Index 10):
A method, comprising:\n responsive to a first tip-out to boosted engine operation, opening a continuously variable compressor recirculation valve (CCRV) by a first amount while increasing a power output by an electric motor coupled to an intake compressor of a turbocharger; and responsive to a second tip-out to un-boosted engine operation, opening the CCRV by a second amount, larger than the first amount, while decreasing the power output by the electric motor.
