A method of analyzing vehicle parameters to distinguish between whether an unexpected vehicle acceleration is due to an internal fault or external forces. The method uses a magnitude and direction ofa change in acceleration for evaluating whether the unexpected acceleration is due to a potential system fault scenario or a potential crash scenario. 种用于通过分析车辆参数来区分车辆的突然加速是由于内部故障还是外力而导致的方法。该方法利用加速度变化的大小和方向来评估突然加速是由于可能的系统故障场景还是潜在的碰撞场景而导致的。
