The invention relates to a vehicle inner wheel difference risk monitoring method and device, computer equipment and a storage medium, and the method comprises the steps: obtaining the distances between two distance measurement radar sensors disposed between a vehicle head and rear wheels at the right side of a vehicle and an obstacle, so as to obtain a first distance and a second distance; calculating coordinates of the obstacle according to the first distance and the second distance; calculating the vertical approaching speed of the obstacle to the vehicle body according to the coordinates ofthe obstacle to obtain an instantaneous speed; calculating collision time according to the relative speed and the coordinates of the obstacle; judging whether the collision time meets the requirements or not; if yes, generating an alarm signal to prompt a driver and pedestrians; if not, judging whether the first distance and the second distance are both not smaller than a set threshold value or not; and if not, generating an alarm signal to prompt a driver and pedestrians. Potential safety hazards existing in the area related to the inner wheel difference are detected in real time, a driver and pedestrians are reminded when the potential safety hazards occur, risk control of the driver is facilitated, and accidents are prevented.

    本发明涉及车辆内轮差风险监测方法、装置、计算机设备及存储介质,该方法包括获取设置在车辆右侧车头至后轮之间的两个测距雷达传感器与障碍物的距离,以得到第一距离和第二距离;根据第一距离和第二距离计算障碍物的坐标;根据障碍物的坐标计算障碍物垂直接近车辆车身的速度,以得到瞬间速度;根据相对速度及障碍物的坐标计算碰撞时间;判断碰撞时间是否符合要求;若是,则生成报警信号,以提示驾驶者和行人;若否,则判断第一距离和第二距离是否均不小于设定阈值;若否,则执行生成报警信号,以提示驾驶者和行人。本发明实现实时检测内轮差所涉及的区域存在的安全隐患,当出现安全隐患时提醒驾驶员和行人,有利于驾驶员控制风险、防止发生事故。
