The invention discloses a vehicle body running posture real-time monitoring system. The working method of the real-time monitoring system comprises the following steps: motion parameters in the running process of a vehicle are obtained, wherein the motion parameters comprise vehicle speed information, vehicle working condition information and driver behavior information; a data acquisition systemsynchronously acquires actual vehicle body posture information, vehicle working condition information and driver behavior information by using a multi-thread technology, the data acquisition system uploads the information to a data processing unit, and the data processing unit fuses and processes the information to obtain an actual vehicle body posture; the data processing unit calculates a vehicle driving safety threshold value, and if the vehicle driving safety threshold value exceeds a preset safety threshold value, the data processing unit stores the safety threshold value and sends out early warning information, early warning is conducted on a driver, and the driver is reminded that the vehicle is in a dangerous state; and if the safety threshold value does not exceed the preset safety threshold value, the data processing unit only stores the safety threshold value. According to the invention, a C + + multi-thread technology is adopted to acquire the data of each sensor in real time, so that the problems of large error and poor monitoring effect caused by different data acquisition frequencies of the sensors are solved.

    本发明公开了一种车身运行姿态实时监控系统,包括如下步骤:获取车辆行驶中的运动参数:运动参数包括车辆自身速度信息、车辆自身工况信息和驾驶员行为信息;数据采集系统利用多线程技术同步采集实际车身姿态信息、车辆自身工况信息和驾驶员行为信息,数据采集系统将上述信息上传给数据处理单元,数据处理单元融合处理上述信息得到所述实际车身姿态;数据处理单元计算出车辆行驶安全域度值,若超出预设安全域度阈值,数据处理单元将安全域度值存储,并发出预警信息,向驾驶员进行预警,提醒驾驶员车辆处于危险状态;若未超出预设安全域度阈值,数据处理单元仅将安全域度值存储。本发明中采用C++多线程技术,对各传感器数据进行实时采集,解决因受各传感器数据采集频率不同的影响导致误差大及监控效果差的问题。
