The invention relates to the technical field of vehicle safety, and provides a collision risk assessment method, a vehicle warning device and a computer readable storage medium. The invention aims to provide more accurate collision risk early warning for a user, and comprehensively assesses the current motion state of the vehicle on the basis of the obstacle orientation measured by the ultrasonic radar system, so that possible collision can be assessed more accurately and truly. Through the collision risk assessment method combining ultrasonic measurement with the vehicle motion state, the measured position of the obstacle and the motion trend of the vehicle are comprehensively considered, the magnitude of the collision risk faced when the vehicle continues to run can be reflected more truly, and therefore reference is provided for driving of a user more visually and efficiently. In addition, the system also has the advantage of overcoming the risk of missed report and false report when the driving direction is not consistent with the gear under the extreme condition of a traditional ultrasonic radar system, such as the conditions of backward sliding on a slope or ice and snow pavements and the like.

    本发明涉及车辆安全技术领域,提供一种碰撞风险评定方法、车辆警示装置及计算机可读存储介质。本发明旨在为用户提供更加准确的碰撞风险预警,以超声波雷达系统测量到的障碍物方位为基础,并综合评估车辆当前的运动状态,从而更加精确真实的对可能的碰撞进行评估。通过将超声波测量与车辆运动状态相结合的碰撞风险评定方法,综合考虑测量到障碍物所处位置和车辆的运动趋势,将能够更加真实的反映车辆继续行驶时所面临的碰撞风险大小,从而更直观高效的为用户的驾驶提供参考。除此之外,其优势还在于可以克服传统超声波雷达系统在极端情况下行驶方向与档位不符时的漏报错报风险,例如斜坡后溜或冰雪路面等情况。
