The invention discloses a method and a device for storing accident data of an automobile data recorder. The method comprises the following steps of: obtaining three-axis acceleration data of a vehicle and speed data of the vehicle; the three-axis acceleration data comprises left-right, front-back and up-down acceleration data of the vehicle; judging whether the three-axis acceleration at the current moment meets a preset condition or not; if yes, recording the state at the current moment as an emergency state, and recording the vehicle state after the moment corresponding to the emergency state; and if the vehicle is completely stopped within 15-30 seconds, marking the driving data at the moment corresponding to the emergency state and 30 seconds before and after the emergency state as important data, and storing the important data. Data are obtained from the vehicle chassis and analyzed to obtain accident data, long-term data needed by the automobile data recorder and the black box can be better provided and stored, and the situation that the automobile data recorder and the black box are affected by a memory and the accident data are circularly covered is avoided.
一种行车记录仪事故数据保存方法与装置,方法包括以下步骤:获得车辆的三轴加速度数据、以及车辆的车速数据;三轴加速度数据包括车辆的左右、前后、上下加速度数据;判断当前时刻的三轴加速度是否满足预设的条件;满足则将当前时刻的状态记录为紧急状态,并记录紧急状态对应时刻后的车辆状态;若在15~30秒内车辆完全停止,则将紧急状态对应时刻及其前后30秒的行车数据标记为重要数据,进行保存。从车辆底盘得到数据并进行分析得到事故数据,能够更好的提供行车记录仪和黑匣子需要长期的数据并储存,避免行车记录仪和黑匣子受内存影响,事故数据被循环覆盖。
