Abstract:
1. A method for detecting spinout on an automotive vehicle, comprising: monitoring a set of conditions on the vehicle, including at least the vehicle's lateral acceleration, forward velocity, and yaw rate; determining whether the set of conditions satisfies a set of criteria; upon a determination that the set of conditions does satisfy the set of criteria, calculating a lateral factor, wherein the lateral factor includes a present lateral factor, defined as a function of the vehicle's lateral acceleration, forward velocity, and yaw rate at the time of measurement, and one or more past values of the lateral factor; computing a spinout factor based on the calculated lateral factor, wherein the spinout factor indicates the difference between the direction of vehicle travel and the direction the vehicle is heading; and generating a warning signal, upon a determination that the spinout factor is above a predefined threshold value; wherein the present lateral factor is defined by ∫(ay−ω
