The invention relates to a method for judging whether a vehicle runs still. The method for judging that the vehicle runs still comprises the steps of recording acceleration values, representing wheelacceleration of the vehicle, of wheels within a specified time period, by at least one sensor element; wherein at least three scanning time points are included in one scanning period, and the acceleration value of the wheel is recorded at each scanning time point; and detecting whether rolling motion exists in the wheel according to the recorded scanning value of the acceleration value, wherein the at least three scanning time points are sequentially arranged in a preset scanning period, and the sampling interval duration between every two adjacent scanning points is the same. The invention provides a method for judging the running stillness of a vehicle, which can effectively judge the state of the vehicle.
本发明涉及一种判断车辆运行静止的方法。该判断车辆运行静止的方法包括使用至少一个传感器元件在指定的时间段内记录表征车辆的车轮加速度的车轮的加速度值;在一个扫描周期内包括至少三个扫描时间点,在每个扫描时间点记录车轮的加速度值;和根据所记录的加速度值的扫描值来检测车轮是否存在滚动运动;其中,至少三个扫描时间点在一个预定扫描周期内依次排列,两个相邻扫描点之间的采样间隔时长相同。本发明提出了一种判断车辆运行静止的方法,能有效判断车辆状态。
