摘要
基于出租车计价器检定背景,研究了低成本MIMU/DGNSS松组合导航模块在车辆里程统计结果及计价器移动检定中的应用。由于传统计价器检定方法过于繁琐,提出了利用低成本MIMU/DGNSS松组合算法处理后的导航定位结果统计车辆行驶里程,实现计价器的在线移动检定,并通过将其与高精度差分GNSS接收机计算的基准里程进行比对,验证低成本MIMU/DGNSS松组合模块里程统计精度。同时,提出了分段里程比对的思路并设计了里程分析软件,避免了累积里程误差的影响,提高了里程比对误差结果的客观性。实验结果表明:低成本MIMU/DGNSS松组合导航模块里程统计精度误差约在8‰范围内,证明了其在里程统计及出租车计价器在线移动检定中的可用有效性。
loosely coupled realise the n algorithm is designed to get the vehicle mileage statistical results and further e mobile verification of taximeter. Then, by comparing the vehicle mileagestatisti cal results with those calculated by high precision differential GNSS reference receiver, the mileage statistics accuracy of the low cost MIMU/DGNSS loosely coupled navigation module can be vet fled. Besides, a new method of the segmental mileage comparison is proposed anda mileageanaly sis software is designed, which can avoid the impact of accumulated mileage error and improve the objectivity of the mileage comparison error result. I.astly, the experimental results demonstrate that the mileage statistical error applicability and effectiveness o tistics and the online mobile ca of the the low bration ntegrated navigation module is within 8 N0, showing the cost loosely coupled navigation module in the mileage sta
