Vehicle information recorder of hybrid power vehicle

Abstract

The invention discloses a vehicle information recorder of a hybrid vehicle, composed of a communication module, a data processing module, and a massive data storing module. The communication module iscomposed of a CAN communication module, a K communication module and a serial port communication module. The CAN communication module and K communication module are connected with relative buses facilitated on the vehicle in order to collect data transmission from the bus. The serial port communication module is connected with a LCD (liquid crystal display) module in order to display error information from electrical control unit of each module on the vehicle and vehicle stratus information such as vehicle speed, etc. By combining with error diagnosis K line and popular CAN line, the invention can collect and discover the errors timely; the data can be stored in a flash disk via USB interface from the PC computer directly, while the recorder can also be connected with the PC computer; thus, it can store data before and after the moment when error occurs; it can also realize long-term storage for all the data completely. The system has the advantages of simple structure, low costs anduse convenience.

Description

technical field [0001] The invention belongs to the technical field of automotive electronics applications, and relates to bus communication, data collection, storage and fault detection technologies of automobiles, and in particular to a hybrid electric vehicle driving state, record and display of states of each electronic control unit of the automobile. It is especially suitable for occasions where a large amount of test data needs to be collected and post-processed during the development or driving of hybrid vehicles. Background technique [0002] With the increasing popularization of automobiles, the depletion of oil resources and the seriousness of environmental pollution, the development of new energy-saving and environment-friendly automobiles has become the focus of everyone's research. A hybrid vehicle is a new type of vehicle with this function. It is the new darling of the automotive industry. The technology is still in the stage of continuous development. The mod...

AI Technical Summary

Problems solved by technology

Specialized fault detection instruments can only perform regular detection, and cannot collect the operating data of related modules, which cannot meet the data requirements during development

However, foreign vehicle information recording systems are not only expensive, but also have some functions that cannot meet their own needs.

There is no in-vehicle networked data acquisition system that specifically collects data on the CAN bus and K lines for hybrid vehicles, and performs mass storage and display of USB flash drives in China.
