便携式车身动态姿态检测系统的设计

Design of Portable Detection System for Car Body Dynamic Posture

为实时掌握汽车在行驶过程中的车身姿态,检测其动态性能,设计了以单片机为控制核心的便携式车身动态姿态检测系统。陀螺仪传感器将采集的汽车三维角速度信号传递给A/D转换器,经过软件系统进行A/D转换和积分处理,在LCD显示器上显示车身在不同时刻的俯仰角、侧倾角和横摆角等动态参数,并进行存储。测试结果表明,该车身动态姿态检测系统工作稳定可靠,满足使用要求。

To test the car body posture and dynamic performance in the process of driving,the portable car body dynamic posture detection system is designed based on MCU.Gyroscope transmits the 3-dimension angular velocity signal to A/D converter,the analog-to-digital conversion and integral processing are conducted by software system,dynamic parameters such as pitch angle,roll angle and yaw angle of the vehicle in different time are obtained and displayed on LCD,and then stored.The feasibility and reliability of this system are verified by testing results,which meets the operating requirement.
