汽车运动参数组合测试系统的研究

Research on Integrated Measurement System of Vehicle Motion Parameters

针对传统汽车运动参数测试手段的不足,研究开发了一种面向汽车道路试验的汽车运动参数DGPS/IMU组合测试系统。详细论述了该组合测试系统的硬件构成、原理和软件设计。该测试系统能够测量输出丰富完备的汽车运动参数信息,包括位置、轨迹、速度、姿态和加速度等。应用该系统进行了汽车运动性能的测试实验与评价,实现了对各种汽车运动参数的长时间高精度与高频率测量。

To overcome the shortcomings of traditional measurement devices, an integrated DGPS/IMU system about measuring vehicle motion parameters is studied and developed, Its configuration , principle and software design are discussed in detail. The integrated measuring system can provide enough and abundant information including vehicle＇s position, trajectory, velocity, attitude and acceleration etc. Many typical vehicle motion tests have been made by use of this integrated measurement system. The results show that it can measure vehicle motion parameters with high frequency and precision for a long time.
