Vehicle-mounted high-speed network test system and method

Abstract

The invention discloses a vehicle-mounted high-speed network test system and method. The system comprises a control unit, a test unit and a tested unit, wherein the tested unit comprises a vehicle-mounted network controller; the control unit is used for generating a test instruction according to test requirements, sending the test instruction to the test unit and generating a test report accordingto test results returned by the test unit; the test unit is used for testing the tested unit according to the test instruction; a test result of the tested unit is received and returned to the control unit; test contents for testing the tested unit comprise a PMA test, an interoperability test, a protocol consistency test, a network performance test, a fault mode test, an Ethernet diagnosis test,an Ethernet flashing test, a gateway routing test, an audio and video transmission test and a network information security test. All contents of the OSI seven-layer model of the vehicle-mounted high-speed network can be tested, and the test coverage is comprehensive. Moreover, various test contents can be tested in parallel, so that the test efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of vehicle network communication testing, in particular to a vehicle-mounted high-speed network testing system and method. Background technique [0002] With the development of automobile intelligence and networking, the amount of data that needs to be transmitted inside the car is increasing, and the requirements for in-vehicle communication bandwidth are also getting higher and higher. The traditional CAN bus can no longer meet the requirements of in-vehicle communication bandwidth. . Therefore, the new vehicle high-speed network, especially the vehicle Ethernet, has become the mainstream network application in the development of the electronic and electrical architecture of today's intelligent networked vehicles due to its characteristics of large bandwidth and low latency. [0003] Vehicle-mounted Ethernet refers to the network communication technology applied to automobiles after the traditional Ethern...
