ABSTRACT:
Turbocharger control systems used with electric assist turbochargers include an electric motor for controlling turbocharger operation. The system comprises an oil pressure sensor attached to the turbocharger for sensing oil pressure for lubricating a shaft bearing assembly. The pressure sensor provides oil pressure information to a control system that controls the operation of the electric motor and/or other operating parameters of the turbocharger and/or the vehicle. The control system regulates operation of the electric motor during operating conditions where a low oil pressure condition is detected when compared to a predetermined minimum. The control system reactivates the electric motor once a desired minimum oil pressure has been detected.
