Problems solved by technology

[0005] However, most of the current methods for analyzing the activity of vehicle functions based on the huge data of the CAN bus mostly use local storage and offline copying to transmit data offline. The data is not real-time, and the sample size is still restricted by storage and copy capabilities.

Embodiment Construction

[0057] The present invention is further described below in conjunction with accompanying drawing:

[0058] see figure 1 , the present invention mainly completes the analysis of the activity of automobile functions through four steps of collection, processing, analysis and visualization:

[0059] 1. Raw data collection, raw data uploaded to hive: monitor the vehicle function signal through 4G Tbox, when the vehicle function signal meets the conditions, Tbox collects the signal and stores it locally, and uploads it to the cloud every 10s.

[0060] 2. Data processing, the original data is formatted through hiveSql: there are data of the day and reissue data in the daily data, after the cloud obtains the data, it is stored in each partition based on the server time, and the reissue is processed and distributed with the sql program The data is sent to the corresponding partition, and the spark calculation program is activated to update the calculation results of the corresponding ...

Abstract

The invention aims to provide a vehicle function activeness analysis method and system. The method comprises the steps of original data acquisition, data processing, data analysis and data visualization. Existing data acquisition hardware is utilized, under the condition that cost and manpower are not increased, a terminal monitors CAN bus data, vehicle function signals are uploaded, a backgroundreceives and stores data, the use frequency and duration of vehicle functions are obtained through data operation, and therefore the function activeness is obtained. The method has data real-time performance and full sample size, can reflect the function activity condition of an actual user, forms multi-dimensional analysis, and meets the requirements of products and operators.

Description

technical field [0001] The present invention relates to analysis techniques for vehicle function activity. Background technique [0002] In recent years, the importance of data has become increasingly prominent in the process of the transformation of OEMs from traditional car manufacturers to service-oriented companies. Vehicles are equipped with more and more functions, and users may be at a loss for such complicated functions. OEMs have also invested a lot of research and development costs in order to carry these bright functions. But how end users evaluate these functions, whether they are used as frequently as expected, and whether users really need these functions are worthy of in-depth research to improve the functional design of the car. At present, most OEMs use offline surveys to obtain evaluation data. This method has disadvantages such as small sample size, poor universality, and high costs. [0003] The data analysis theory of the existing terminal APP is very ...
