The invention provides an automatic test system of an automobile. The automatic test system comprises a power supply, a signal simulation unit, an ECU to be tested, a signal transceiver and an upper computer, wherein the power supply is used for providing a voltage for the signal simulation unit, the signal simulation unit is used for providing a simulation signal for the ECU to be tested, the signal transceiver is used for receiving and sending request information and transmitting data by a CAN bus, the upper computer is used for performing parameter configuration on the signal simulation unit, performing automatic test and generating a test report, the power supply is connected with the signal simulation unit, the signal simulation unit is connected with the ECU to be tested and the upper computer, and the ECU to be tested is connected with the upper computer by the signal transceiver. By the automatic test system, an automatic diagnosis test platform of the automatic ECU is built, the parameter configuration is performed by the upper computer, an input-output signal is simulated to do diagnosis test, various complicated diagnosis fault codes can be tested, and the fault diagnosis efficiency and the diagnosis fault accuracy of the automobile are improved.
Description
technical field [0001] The invention belongs to the field of automatic testing, in particular to an automatic testing system for automobiles. Background technique [0002] The on-board computer for automobiles is a special microcomputer controller for automobiles in terms of use. It is the same as an ordinary computer. (A / D) and shaping, driving and other large-scale integrated circuits. With the rapid development of our country's economy, cars have entered ordinary families, and cars have become an indispensable part of people's daily life. After-sales services for cars are becoming more and more important, and good after-sales services are based on car diagnosis. Perfect diagnostic service and ECU testing are the main guarantees. Traditional diagnostic support services can pass the diva test, but testing and diagnosing faults is more complicated, time-consuming, costly, and inefficient. Contents of the invention [0003] In view of this, the present invention aims to ...
