The invention provides an implementation method for detecting continuous lane change of a vehicle, which comprises the following steps of: carrying out integral processing on an average value of stored and acquired yaw angle and Z-axis angular velocity data, and solving integral change of the average value; whether the integral change value of the Z-axis average value exceeds a preset lane changing angle threshold value or not is judged, if yes, it is judged that the vehicle changes the lane, and when it is detected that the vehicle changes the lane, a double linked list node is created, the time node of vehicle lane changing is stored, and meanwhile whether current lane changing is first lane changing or not is checked; and when it is detected that the vehicle continuously changes lanes for three times in a short time, the time difference between the current lane change and the first lane change is calculated, and if the time difference is smaller than or equal to a preset threshold value, it is judged that the vehicle has a frequent lane change behavior. The driving track of the vehicle can be tracked in real time, accurate detection of the continuous lane changing behavior of the vehicle is achieved, and whether a driver has the abnormal driving behavior of frequent lane changing or not is further judged.

    本发明提供一种用于检测车辆连续变道的实现方法,其包括对存储获取到的偏航角和Z轴角速度数据的平均值进行积分处理,求出平均值的积分变化;判断Z轴平均值的积分变化值是否超出预设的变道角度阈值,若超出,则判定车辆正在变道,当检测到车辆正在变道时,并创建一个双向链表节点,存储车辆变道的时间节点,同时检查当前变道是否为首次变道;当检测到车辆在短时间内连续三次变道时,计算当前变道与首次变道之间的时间差,若该时间差小于或等于预设的阈值,则判定车辆发生了频繁变道行为。本发明能够实时跟踪车辆的行驶轨迹,实现车辆连续变道行为的精准检测,并进一步判断驾驶员是否存在频繁变道的异常驾驶行为。
