  • Systems and methods for real-time angle-domain measurement of filtered cylinder pressure
    Patent number: 9719435
    Abstract: Techniques for measuring cylinder pressure include receiving an analog cylinder pressure signal indicative of pressure in a cylinder of an engine and an angular position signal indicative of an angular position of the engine. The analog cylinder pressure signal is converted to a digital cylinder pressure signal by (i) windowing the analog cylinder pressure signal in the angle-domain using the angular position signal and (ii) sampling the windowed analog cylinder pressure signal in the time-domain, and the digital cylinder pressure signal is filtered in the time-domain to obtain a filtered digital cylinder pressure signal. A measured pressure in the angle domain is obtained by sampling the filtered digital cylinder pressure signal using the angular position signal, and operation of the engine is controlled using the measured cylinder pressure.
