Abstract:
Methods and systems are provided for controlling boost pressure in a staged engine system comprising a turbocharger and an upstream electric supercharger. In one example, a method may include accelerating an electric supercharger to choke the flow of air to the engine in the event of turbocharger overboost.

Claim (Index 20):
An engine system, comprising:\n a direct injection engine having an intake; a first intake compressor driven by an electric motor, the motor powered by a battery; a second intake compressor driven by an exhaust turbine, the second compressor positioned downstream of the first compressor along the intake; a bypass including a bypass valve coupled across the first compressor; a wastegate including a wastegate valve coupled across the exhaust turbine; and a controller with computer readable instructions stored on non-transitory memory for: in response to an operator pedal tip-in while the second compressor is spinning, closing the wastegate valve to adjust a speed of the second compressor; and concurrently adjusting a speed of the first compressor to limit airflow into the second compressor, wherein operation of the first compressor is further adjusted based on an altitude of operation of the engine system.
