智能车载感知与侧翻预警系统的设计

为了防止汽车在行驶过程中发生侧翻,使汽车始终处在安全工况下行驶,减少交通事故,设计了一种基于ARM9的智能车载感知和侧翻预警系统,对汽车在途行驶时的侧倾角和侧倾角速度进行监测,并采用多阶递推模型对汽车侧倾姿态进行预测,当预测到侧倾达到极限工况时发出报警信息,提醒驾驶人员注意并采取相应减少侧向加速度的措施,从而达到预防汽车侧翻事故的发生,并基于VB2005,Matlab和NIMeasurement Studio开发了车载感知与侧翻预警系统软件,进行了系统仿真。实车道路试验与系统仿真实验进行了比较,结果表明:车载感知和预警系统能够及时准确预测汽车侧翻,提高汽车主动安全。

Design of intelligent vehicle perception and rollover warning system

In order to prevent car rollover while moving,and to make the car always in a safe driving condition and to reduce traffic accidents,an ARM9-based intelligent vehicle perception and rollover warning system is designed.Monitor the roll state of the car when driving and multi-level recursive model is used to predict the vehicle roll attitude.When the predicted roll reach to the limit conditions,trigger the alarm to remind driver to be careful and to take appropriate method to prevent vehicle rollover accidents,and further improve the vehicle active safety performance.Road experiments are designed,Matlab is used to compare the predicted values with experimental data.The results show that vehicle perception and rollover warning system can predict vehicle rollover timely and accurately,which can improve vehicle active safety.
