【摘要】 随着车载导航行驶记录仪系统集成度的不断提高，产品的性能和稳定性问题层出不穷。快速评测和确定车载导航行驶记录仪系统的性能指标和质量结果越来越困难。为此本课题研究提出一种针对车载导航行驶记录仪系统的性能评测方法。通过建立车载导航行驶记录仪系统的性能指标体系，设计系统的评测试验方法和评测流程，用可视化的方式分析被测系统的质量状况。从而解决快速有效的评测一套车载导航行驶记录仪系统性能的问题。对车载导航行驶记录仪的性能指标设计，基于系统架构和特征的分类，对系统的空间导航数据显示效率和合理性、时空行驶记录数据准确性和及时性、导航路径规划的效率和合理性、车载导航行驶记录仪系统的综合性能等方面，设计出一套性能评测的指标体系。结合车载导航和行驶记录仪的行业标准，提出系统各部分的性能评测指标阈值。确定车载导航行驶记录仪的性能指标测量方法，需要根据被测系统的特征，通过等价类分析的方式，设计出具有代表性和满足覆盖率要求的系统性能评测用例集合。基于系统的空间导航数据和时空行驶记录数据量大，难以目视分析的现状，设计一套对空间导航数据的评测结果、时空行驶记录数据分析和导航路线规划结果的可视化分析方法。通过搭建对车载导航行驶记录仪的性能指标评测系统，设计开发自动化的系统性能评测工具，实现对被测的车载导航行驶记录仪系统的空间数据显示性能、时空行驶记录数据记录的性能、导航路径规划的效率和结果等方面实现自动化评测的过程。将评测结果进行可视化处理和分析，满足对车载导航行驶记录仪系统的快速回归验证和可视化结果分析的需要。本课题研究通过建立一套车载导航行驶记录仪系统的性能评测指标和评测方法，能够快速有效的评测被测系统的性能指标达成程度。经过大量实验实验表明，本课题所提出的性能指标和评测方法，不仅能确定车载导航行驶记录仪系统的性能指标，而且对快速完成评测过程，为系统的性能和可靠性优化提供依据。更多还原

【Abstract】 With the increasing of integration for the car navigation and travelling datarecorder system, there are increasingly problems of performance and stability appeared,and the performance indicators and the quality results of rapid determination systemare becoming increasingly difficult. Therefore, this research project will provide anevaluating method for the performance indicators of the car navigation and travellingdata recorder system. Through establishing the performance system of car navigationand travelling data recorder system, design the system of evaluation test method andevaluation process, and using the visual way to analysis the quality of the system undertest. Thus could solve the problem of evaluating the car navigation and travelling datarecorder system effectively and rapidly.The performance indicators design of the car navigation and travelling datarecorder, basic on system architecture and feature classification, to display theefficiency and rationality of the spatial navigation data system, the accuracy andtimeliness of the spatial data travelling data recorder, and the efficiency and rationalityof the route planning, for designing an indicator system of performanceevaluation.Combine with the industrial standard of vehicle navigation and travellingdata recorder, providing the indicator threshold of performance evaluation for eachpart.To determine the test method of performance indicator for navigation travellingdata recorder, it needs basic on the features under test system, through the approach ofequivalence class analysis, design the system performance evaluation case collectionwhich satisfy the coverage rate requirement with representativeness. Basic on thesituation that huge spatial and spatio-temporal data is difficult to visual analysis,design a visualization analysis method for space navigation evaluation results,spatio-temporal running record data analysis and navigation route planning results.Through establish the evaluation system and the performance indicators of carnavigation and travelling data recorder system, design and develop the automatedsystem performance evaluation tools, realization of the automated evaluation processfor space displaying data, spatio-temporal travelling data recorder’s data, and navigation route planning results under test. To visualize the results, satisfy therequirement of rapid regression verification and visual result analysis under test.This research project could evaluate the degree that performance indicatorsreached under test through establish an evaluation method of performance for the carnavigation and travelling data recorder system. A large number of experiments showthat providing the performance indicators and the performance evaluation methodscould confirm the performance indicators of car navigation and travelling data recordersystem, and providing the evidences for rapid completion of evaluation, system’sperformance and reliable optimizing.更多还原
