SYSTEMS AND METHODS FOR CONTROL OF TURBOCHARGER WASTEGATE

摘要

A system includes an internal combustion engine including an intake manifold and a throttle disposed upstream of the intake manifold. The system also includes a turbocharger coupled to the internal combustion engine, wherein the turbocharger includes a turbine and a compressor. The system further includes a wastegate coupled to the turbine. The system yet further includes a controller configured to receive a first signal representative of a compressor discharge pressure from a first sensor and a second signal representative of the intake manifold pressure from a second sensor, to determine a differential pressure across the throttle based on the first and second signals, to determine a position of the wastegate solely based on the differential pressure, and to adjust the wastegate to the position.
