Abstract
A turbocharger control system for a high-pressure turbocharger and a low-pressure turbocharger includes a turbo mode determination module and a transition control module. The turbo mode determination module determines a transition from a dual turbo mode to a single turbo mode. The high-pressure turbocharger is active in the dual turbo mode and idle in the single turbo mode. The transition control module determines a turbine efficiency of the high-pressure turbocharger and controls the high-pressure turbocharger during the transition based on a predetermined maximum turbine efficiency equation.
