    摘要： A control system for an engine includes an air calculation module that determines, based on a plurality of first coolant temperatures sensed during a period of engine operation, a first cumulative mass of intake air combusted by the engine during the period that corresponds to an estimated amount of heat dissipated by a cooling system of the engine during the period, and that determines, based on the first cumulative mass, a second cumulative mass of intake air of the engine that is required to raise a temperature of the engine from an initial temperature at a start of the period to a target temperature. The control system further includes a control module that selectively adjusts one of a diagnostic condition and an operating condition of the engine based on the second cumulative mass. A related method for controlling an engine is also provided.

    摘要： A control system for diagnosing a fuel system of a vehicle is provided. The system generally includes a correction term module that estimates a fuel correction term based on a first fuel correction value and a second fuel correction value, wherein the first fuel correction value is based on a first period and the second fuel correction value is based on a second period, and wherein the first period is longer than the second period. A diagnostic module diagnoses the fuel system of the vehicle based on the fuel correction term.

    摘要： A control system for a vehicle is provided. The control system includes a signal processing module that receives a sensor signal and extracts a plurality of sample points from the sensor signal. A computation module computes a summation of the sample points, computes a summation of squares of the sample points, and computes a standard deviation based on the summation of the sample points and the summation of the squares of the sample points. A control module generates a control signal based on the sensor signal and the standard deviation.

    摘要： An engine control system includes a digital signal processing (DSP) module that generates a fast Fourier transform (FFT) of an engine knock signal generated by an engine knock sensor. An intensity determination module determines an engine knock intensity based on one of a maximum of and an average of the FFT. A status determination module determines a status of the engine knock sensor based on the engine knock intensity, a plurality of predetermined knock intensity thresholds, and a rotational speed of an engine crankshaft.
