摘　　要：分析了车内环境对行车安全的影响,根据车内环境多元化、复杂化的特点研究了对车内环境的评价,进而构建了一套较为完善的综合评价行车安全的车内环境的理论。其中包括:运用改进的韦伯-费希纳定律评价模型确定车内环境分级标准;运用改进的综合集成赋权模型确定各评价指标的权重;基于模糊综合评价模型和检测到的各要素含量,通过计算模糊关系矩阵、指标权重矩阵,得出行车安全的车内环境综合评价结果。在此基础上,利用STM32F103单片机、液晶显示屏、气体传感器、ATK-NEO-6M、ATK-SIM900A等硬件及相关软件,设计了一套能够实时检测、评价、显示、定位、预警、传送车内环境各要素指标的车载预警系统,实测结果表明,该系统达到了预期的检测、评价效果。The influence of the environment in a vehicle for safe driving was analyzed, the evaluation of the in-vehicle en- vironment was studied under the consideration of its characteristics of diversification and complication, and a set of more perfect theories for comprehensive evaluation of the environment in vehicles were built, including determina- tion of the grading standards of the environment in vehicle using the improved Weber-Fechner law evaluation mod- el, determination of the weight level of each evaluation index using the improved integrated weight model, and ob- taining of the comprehensive evaluation results based on the fuzzy synthetic evaluation model as well as the compu- tation of the matrixes of fuzzy relation and index weight. Based on the above-mentioned work, theories for a vehicle- mounted early warning system for real time detection, evaluation, display, position, alarm, deliver of vehicles＇ in- terior environment was designed and implemented by using STM32F103 microcontroller, LCD display, gas sensors, ATK-NEO-6M, ATK-SIM900A, and other hardwares and relational softwares. Which achieved the desired effect in practical applications.
