CONTROL SYSTEM FOR ELECTRICALLY ASSISTED TURBOCHARGER

摘要

System for controlling an electric assisted turbocharger (10) including an electric motor (12) disposed within the turbocharger, and an electric motor controller (26) 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 (32) 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 and boost pressure control dampening, and can be used to produce electricity from the electric motor depending on the particular operating condition.
