Embodiment Construction

[0032] As mentioned in the background technology, the traditional ECU upgrade test mainly relies on manually building a test environment, and upgrades a dedicated ECU through a dedicated host computer tool. Usually, each test can only be performed once for the same type of ECU. Upgrade test . This test method has low efficiency and low repeatability. And because the working mode of the remote ECU upgrade based on the domain controller is more complicated, the traditional method cannot be effectively tested.

[0033] In view of this, an embodiment of the present application provides an ECU upgrade test system, including: a terminal emulation node, a cloud emulation node connected to the terminal emulation node, a domain controller emulation node connected to the cloud emulation node, and A multi-core cable is connected to the cable transition box of the domain controller emulation node; wherein,

[0034] The cable transition box includes multiple types of communication interf...

Abstract

The invention discloses an ECU upgrading test system. The system is composed of a terminal simulation node, a cloud simulation node, a domain controller simulation node and a cable switching box; the domain controller simulation node is connected with the cable switching box through a multi-core cable; the cable switching box comprises multiple types of communication interfaces, therefore, the connection with various ECUs is realized. According to the ECU upgrading test system, the nodes and the cable switching box are utilized to simulate the whole process from initiating an upgrading request by a terminal to upgrading various ECUs; and full-automatic test of different upgrading channels can be realized by operating the domain controller simulation node through interaction between the terminal simulation node and the cloud simulation node, and therefore, the stability and reliability of the function of remote ECU upgrading of the domain controller are verified; and moreover, the ECU upgrading test system can realize upgrading test of a plurality of same or different types of ECUs at the same time, so that the ECU upgrading test efficiency is greatly improved.

Description

technical field [0001] The present application relates to the technical field of vehicle engineering, and more specifically, relates to an ECU upgrade test system. Background technique [0002] With the development of automotive electronic technology, there is a trend of centralization of automotive electronic systems, and the decentralized ECU (Electronic Control Unit, Electronic Control Unit) in the traditional design mode is gradually replaced by centralized domain controllers and central computers. As a basic function of automotive electronic systems, ECU upgrades have high requirements for its stability and reliability. However, in the current centralized processing scenario, there is still no solution for how to automate the testing of ECU remote upgrades. [0003] The traditional ECU upgrade test mainly relies on manually building a test environment, and upgrades a dedicated ECU through a dedicated host computer tool. Usually, each test can only be done once for the ...
