摘要： Methods and systems are provided for expediting turbine spool up during an engine restart following an engine stop while a vehicle is in motion. In one example, a method includes, in response to engine restart conditions being met, operating an electrically driven compressor to supply compressed air to a turbocharger turbine for expedited turbine spool up during engine cranking.
