SUPERTURBOCHARGER CONTROL SYSTEMS

摘要

Disclosed is a control system and method for controlling a superturbocharged engine system in various operation modes. Throttle control mode may idle the superturbocharger during low and medium engine loads, so that boost is not created in the intake manifold. During high engine load conditions (open throttle), boosting occurs in response to the driver, operator, or control system requesting increased engine loads. For steady state control mode, the control system may receive a plurality of input data, an actual/current control data input, look up a desired value for the control input, compare the desired to the actual control input, and perform control logic on the comparison results to obtain an updated continuously variable transmission ratio to control the superturbocharged engine system independent of throttling on the engine.
