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.

Abstract: Systems for preventing/controlling compressor surge in an electrically assisted turbocharger comprise a turbocharger having an electric motor disposed around a turbocharger shaft. The electric motor controller is electrically coupled to the electric motor for controlling the rotational movement provided by the electric motor to the turbocharger shaft. A memory is electrically coupled to the electric motor controller and comprises a multi-dimensional map of compressor surge conditions stored therein. Sensors are used to provide desired engine and/or turbocharger operating information for comparing against the stored map data. The sensors are electrically coupled to the electric motor controller. The controller plots the actual operating information provided by the sensors on the stored map to evaluate whether the turbocharger is operating in different operating regions. If the plotted turbocharger operation falls within a surge risk or surge state operating region, the motor controller operates the electric motor in a manner that reduces the rotational speed of the turbocharger shaft.

Abstract: System for controlling an electric assisted turbocharger comprise an electric motor disposed within turbocharger, and an electric motor controller electrically coupled thereto for purposes of controlling the same. A memory is electrically coupled to the electric motor controller and is configured with a condition map that correlates electric motor instructions with engine and turbocharger conditions. The system includes sensors that are electrically coupled to the electric motor controller, and that are configured to sense conditions of at least one of the turbocharger and the internal combustion engine that is coupled thereto. The electric motor controller is configured to control the electric motor based upon the input received from the plurality of sensors as compared to the data contained multi-dimensional condition map. The system provides electric motor speed control, boost pressure control dampening, and can be used to produce electricity from the electric motor depending on the particular operating condition.
