摘要
为了适应智能车辆辅助驾驶系统对驾驶和车辆状态监测的要求,利用MEMS惯性传感器自主设计了微惯性测量单元,并结合GPS设计了一种驾驶行为和车辆状态监测系统,实现对驾驶员操纵动作的感知、汽车6自由度运动状态参数和汽车运行车速的实时监测。介绍了MEMS传感器的选型,设计,安装和布置。实车道路实验结果表明:系统对驾驶员踩踏刹车踏板、离合器踏板和变换档位的操纵动作的感知效果较好,侧向加速度和方向盘转角的理论识别曲线与实车实验曲线在趋势上比较吻合。该系统为开发驾驶人员操纵动作自动识别系统提供理论基础和技术支持,也可为提高汽车行驶性和安全性提供重要的理论依据和工程应用指导。
A driving behavior and vehicle motion monitoring system is developed to realize the Perception of the driver maneuvers, the real-time monitoring of vehicle 6 degree of freedom motion state parameters and vehicle running speed based on micro inertial measurement unit （ MIMU ） , which is designed by MEMS inertial sensors, and GPS for driver surveillance in intelligent vehicle assistant driving systems. Type selection, design, installation and layout of MEMS sensors are introduced. The vehicle road test results show that the system perceives well in the driver depresses the brake pedal, clutch pedal, and maneuvers transform stalls. The theoretical identification curve of the lateral acceleration and steering angle matches well with vehicle test on the trend. The system provides a theoretical basis and technical support for the development of driver maneuvers automatic identification system, also provides an important theoretical basis and engineering applications guidance to improve the vehicle driving and safety.
