Embodiment Construction

[0052] The present invention will be further described below in conjunction with accompanying drawing.

[0053]With the development of chip technology, Ethernet technology has entered the automotive industry, and the functions that the on-board controller can achieve become more and more complex, resulting in an increase in the code volume of the on-board controller. Whenever the controller needs to update the program, It is often necessary to write dozens of megabytes of data, and some controllers even have hundreds of gigabytes of code. If you use the 500kb / s CAN bus for flashing, even if the data is transmitted under full load, It also takes tens of minutes to several hours to complete. If you use the automotive Ethernet DoIP flashing, the flashing speed of the controller can be greatly improved, and the update efficiency of the controller program can be improved. Therefore, based on the L3 vehicle architecture, Ethernet DoIP flashing for the controller has become a trend. ...

Abstract

The invention relates to a vehicle-mounted Ethernet DoIP diagnosis flashing test method and system based on an L3 whole vehicle framework. The system comprises an upper computer, bus acquisition equipment, a programmable power supply, a board card and an Ethernet node; the upper computer is connected with the bus acquisition device, the bus acquisition device is connected with the Ethernet node, the upper computer is simultaneously connected with the programmable power supply, the programmable power supply is connected with the board card, and the board card is connected with the Ethernet node; the upper computer controls the programmable power supply and the board card through scripts, automatically controls upper and lower motor fault injection of a tested Ethernet node, and realizes upper and lower power logic test and fault code test of diagnosis and flashing; the upper computer controls the bus acquisition equipment through scripts, simulates the sending of Ethernet DoIP diagnosis and flashing diagnosis service messages, and monitors and collects an Ethernet DoIP diagnosis message. According to the invention, the diagnosis and flashing functions of the Ethernet DoIP can be rapidly tested, and the problem point can be accurately positioned.

Description

technical field [0001] The invention relates to the technical field of vehicle detection, in particular to a vehicle Ethernet DoIP diagnostic flash test technology based on L3 vehicle architecture. Background technique [0002] In the new electrical architecture of automobiles, Ethernet already exists as a new type of network. Many functions in the Ethernet bus network need to be implemented through diagnostic services, such as online programming (FBL), production line inspection, calibration matching, and reading fault information. And data flow, etc. These diagnostic functions involve a series of processes of the vehicle from the production line to the after-sales service of the 4S shop. The correctness and reliability of vehicle Ethernet DoIP diagnostic flashing are crucial to the use of vehicles. Functions such as FBL and production line electrical inspection need to be applied during the development process of the controller. The development and testing time is short, ...
