Description
Technical field
The present invention relates to new-energy automobile detection field, more specifically, relate to a kind of car load network test system being applied to new-energy automobile.
Background technology
Lack of energy, constantly riseing of automobile pollution, and the general requirement of national governments' energy-saving and emission-reduction, each large car manufactures in the whole world carries out new-energy automobile exploitation one after another, and new-energy automobile will become the grand strategy direction of automobile industry transition.At present, China has become the first in the world automobile production and marketing state, and within one longer from now on period, the automobile volume of production and marketing of China also will keep quick growth, and expecting the year two thousand twenty automobile pollution will more than 2.5 hundred million.Therefore, propulsion energy-saving and new-energy automobile industrialization, promoting industrial transformation upgrading is implement the Party Central Committee, State Council about energy-saving and emission-reduction and the important path of general requirement cultivating emerging strategic industries.
Along with the development of this new industry of new-energy automobile, the application of new technology is absolutely necessary.The application of CAN network technology is exactly one of gordian technique wherein.CAN controller LAN is the abbreviation (hereinafter referred to as CAN) of Control ler Area Network, is the serial communication protocol of ISO International standardization.In automobile industry, for the requirement to security, comfortableness, convenience, low public hazards, low cost, various electronic control system is developed.Owing to communicating data type used and being not quite similar to the requirement of reliability between these systems, situation about being made up of multiple bus is a lot, and the quantity of wire harness also increases thereupon.For adapting to the needs of " reducing the quantity of wire harness ", " by multiple LAN, carrying out the high-speed communication of mass data ", within 1986, electric business Bosch of Germany develops the CAN communication agreement towards automobile.After this, CAN has carried out standardization by ISO11898 and ISO11519, has been the standard agreement of automotive networking in Europe.Its a kind of serial data communication agreement being exchanges data for solving in Hyundai Motor between numerous control and testing tool and developing, it is a kind of multi-master bus, communication media can be twisted-pair feeder, concentric cable or light transmitting fiber, and traffic rate reaches as high as 1Mbps.
The initial appearance of CAN is because consumer at that time gets more and more for the requirement of automobile function, and the realization of these functions is based on electronically controlled mostly, this becomes increasingly complex with regard to making the communication between electronic installation, means the more signal connecting line of needs simultaneously.The initial motivation of proposition CAN is exactly the communication in order to solve between electronic-controlled installation huge in Hyundai Motor, reduces ever-increasing signal wire.So just devise a single network-bus, all peripheral components can be articulated in this bus.1993, CAN became international standard, i.e. ISO11898 (high-speed applications) and ISO11519 (low-speed applications).In North America and West Europe, CAN agreement has become the STD bus of Computer Controlled System for Vehicle and built-in industrial control area net（CAN）, and have with CAN be underlying protocol aim at high capacity waggon and heavy industry motor vehicles and machines design J1939 agreement.In recent years, its high reliability had and good error detection capability more and more come into one's own, and be widely used in that automotive field, computer control system and environment temperature are severe, electromagnetic radiation is strong and vibrate large industrial environment.
New-energy automobile is in the flourish stage, and the competition of industry has penetrated into the every aspect of technology and market.CAN is occupied an leading position in automobile bus, and new-energy automobile needs inherit and develop the application of bus on automobile.The CAN network workbench that can be applied to each subsystem of car load is at present also less, most of test macro is all carry out functional test with single controller node, each subsystem software such as CANoe, CANscope, CANstress of German Vector company is such as adopted to test one by one, so not only extend car load debugging cycle, nor be beneficial to operating personnel learn fast application.In future, in order to adapt to large-scale production task, reduce the production test time of single product, raise labour productivity, car load network workbench is indispensable easily.
At present, existing technical scheme just carries out test job comparatively fully for the vehicle body network in car load network, and relating to less to the joint test work of power network, the joint test of power network can only carry out real steering vectors after car load has been assembled and it is mainly used on traditional fossil fuel automobile.Therefore, once go wrong after finding power network test and cause and do over again, there will be larger human and material resources and leeway thus.
Summary of the invention
The present invention completes based on the following fact and cognition.
At present, existing technical scheme just carries out test job for the part vehicle body network in car load network, and relates to less to the work of power network joint test, and it is mainly used on traditional fossil fuel automobile.And new-energy automobile and traditional fossil fuel automobile are essentially different, the electric pressure of traditional vehicle is that the low-pressure system of 12V is powered, and the electric pressure of the pure electric automobile hyperbaric environment system that to be 336V even higher, therefore the two faced by car load electromagnetic environment (EMC) be as far apart as heaven and earth, and electromagnetic interference (EMI) is also affect one of key factor that can finished vehicle electronic electrical equipment and car load network system work normally.
Therefore, when carrying out the test job in entire new energy automobile electronic apparatus, must consider that the high voltage component of car load is under the condition of the work of intervention, test detailed is respectively carried out for the vehicle body network in car load network, power network, charging network, such test result that could ensure pure electric automobile better, thus, workbench just must possess high voltage component and carry function, and the technical scheme of traditional vehicle is blank in this, new-energy automobile especially whole pure electric vehicle network test requirements therefore cannot to be met.
