摘要： An outside air temperature (OAT) diagnostic system includes an ambient temperature monitoring module that receives (i) an OAT signal from an OAT sensor and (ii) an intake air temperature (IAT) signal from an IAT sensor of an engine. The ambient temperature monitoring module compares the OAT signal to an IAT signal and generates a first difference signal. A performance reporting module determines whether the OAT sensor is exhibiting a fault and generates an OAT performance signal based on the first difference signal.

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 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.
