AUTOMATED TREND DETECTION

Abstract:

A method includes acquiring a current condition indicator of a condition indicator set associated with an operating condition of a vehicle, the condition indicator set indicating sensor readings associated with an operating element of the vehicle under the operating condition, determining, by a data server, a volatility over a window of the condition indicator set based, at least in part, on differences between adjacent data points in the window, wherein the window includes the current condition indicator, determining, by the data server, a movement over the window of the condition indicator set based, at least in part, on a difference between two selected data points in the window, determining a volatility-based movement significance over the window of the condition indicator set based, at least in part, on a ratio of the movement to the volatility, determining, by the data server, whether a trend associated with the operating element is indicated based, at least in part, on the volatility-based movement significance, and generating, by the data server, an alert signal in response to the determining that the trend is indicated.
