The invention relates to the technical field of vehicles, and discloses a vehicle rollover detection and alarm method and system.The vehicle is provided with a vehicle-mounted terminal, and the method comprises the following steps that the initial acceleration of the vehicle when the vehicle gets off the line is obtained; the acceleration value of the vehicle in the driving process is obtained; calculating an included angle alpha between the acceleration and the acceleration; the alpha is compared with a defined Alpha angle, if the alpha is larger than the Alpha angle, rollover occurs, and the vehicle-mounted terminal automatically gives an alarm; if alpha is smaller than or equal to the Alpha angle, rollover does not occur, and no alarm is given. According to the vehicle rollover detection and alarm method and system provided by the invention, detection and automatic alarm are realized when the vehicle rollover occurs based on the vehicle-mounted terminal, and the safety of the vehicle is improved.
本发明涉及车辆技术领域,公开了一种车辆侧翻检测及报警的方法及系统,其中车辆上配置有车载终端,该方法包括以下步骤:获取车辆下线时的初始加速度;获取车辆在行驶过程中的加速度值;计算加速度与之间的夹角α;将α与定义的Alpha角度进行比较,若α大于Alpha角度,则发生侧翻,车载终端自动报警;若α小于或等于Alpha角度,则未发生侧翻,不报警。本发明提供的车辆侧翻检测及报警的方法及系统,实现了基于车载终端实现车辆在发生侧翻时检测及自动报警,提高了车辆的安全性。
