In-vehicle environment detection method and detection system

Abstract

The invention discloses an in-vehicle environment detection method and detection system. The in-vehicle environment detection method includes the steps of collecting in-vehicle sensor data; calculating the grade of a direct feeling module and the grade of a danger coefficient module; determining the weights of the direct feeling module and the danger coefficient module and solving the grade of the overall comfort level; predicting the trend of each index according to historical data; using one kind of sensor data as a comparison index and others as reference indexes, calculating the degree of association of the reference indexes and the comparison index, obtaining predicted value of the comparison index, calculating data of the reference indexes corresponding to the predicted value of the comparison index, judging whether the predicted value reaches a dangerous value within time t, and if no, outputting ideal temperature and humidity and overall comfort level. According to the in-vehicle environment detection method provided by the invention, various environmental data in a vehicle are monitored in real time through a sensor, the comfort degree of environment in the vehicle under a current state is calculated, the basis of in-vehicle environment conditioning is given according to optimal environmental data, and thus conditioning is facilitated to obtain a better taking environment.

Description

technical field [0001] The invention belongs to the technical field of intelligent vehicles, and is a detection method and a detection system established by effectively integrating advanced computer technology, sensor technology, wireless communication technology and embedded micro-control technology and applying them to vehicle interior environment monitoring. Background technique [0002] With the popularity of small family cars and the continuous development of autonomous driving technology, the environment inside the car has become one of the environments people often live in. The sensor technology can realize the real-time monitoring of the environment inside the vehicle, process the environmental data and realize the control through the single chip microcomputer, and embed the single chip microcomputer into the control module of the car, so as to realize the self-adaptive adjustment of the inside environment of the vehicle, that is, to automatically adjust the environme...

Problems solved by technology

In this literature, the number of samples is large, the analysis is more detailed, and the environmental factors considered are more comprehensive, but it is not possible to judge the comfort in the car in real time. It is only the overall comfort evaluation result established by statistically evaluating the comfort of the respondents , and there are significant differences in the comfort evaluation of passengers on high-speed trains of different models, which is not suitable for real-time environmental monitoring in small family cars
