Abstract

The invention discloses an automatic testing device comprising a power module, a signal generator, a bus interferometer, a test interface module, an oscilloscope, a bus test module, a simulation module and a network test engine, which are integrated together. The automatic testing device disclosed by the invention can automatically achieve a physical layer consistency test of a CAN / LIN bus networkcontroller (ECU), a data link layer consistency test, a robustness test, a diagnostic test, a gateway routing test and a network management protocol test (AUTOSAR) and so on via different test modules; and compared with the manner of accomplishing the test process by the test personnel, the automatic testing device has the advantages of saving labor, and improving the work efficiency and the accuracy of test results.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to an automatic testing device. Background technique [0002] The vehicle factory will test the CAN / LIN bus of the electronic control unit. The specific content of the test may include: short-circuit or open-circuit the power line, ground line, CAN_H, CAN_L, LIN and other signal lines; use different test circuits to Power line, ground line, CAN_H, CAN_L, LIN and other signal lines realize terminal matching, threshold test, internal resistance test, wake-up function test, bus interference tester interface test, robustness test and other bus tests. [0003] In the process of realizing the present invention, the inventor found that the following problems exist in the prior art: the existing testing methods are mainly based on manual testing, and there are situations such as low testing efficiency, long cycle, low accuracy rate, and single testing. It cannot meet the high requirements...
