Abstract

The invention discloses and relates to a CAN (Controller Area Network) test system and test method. The system comprises an ECU (Electronic Control Unit), a power supply control unit, a programmable power supply, a stabilized voltage power supply, CAN bus data collecting equipment, a CAN bus interferometer, a network oscilloscope, a test host, a test control plate card and a bus test plate card. The method comprises the following steps of 1, inputting demand test information; 2, preparing test cases; 3, selecting the test cases according to requirements; 4, building a CAN bus network automatictest system; 5, judging whether the generation of test reports is needed or not through conditions; 6, analyzing the test cases in the steps; 7, testing data, and identifying and guiding the test data into a corresponding data table. The system and the method have the beneficial effects that the defects of manual test are overcome; the condition that the manual test equipment building work is performed when the test starts at each time is avoided; the operation efficiency is improved; the artificial errors generated in the test process are avoided.

Description

technical field [0001] The invention relates to a CAN network test system and a test method, belonging to the technical field of pure electric vehicle electronic control technology. Background technique [0002] At present, automobiles, as a technology-intensive and industrial process-intensive comprehensive industrial product, represent the overall industrial development level of a country or region. With the rapid development of the automobile industry, the focus of automobile technology has gradually shifted from traditional mechanical engineering to the field of electronic control engineering. The electronic equipment in automobiles is increasing. Electronic Control Unit (ECU) (hereinafter referred to as : The number of ECU units is also increasing, and the uninterrupted real-time communication and information interaction between the control units form a complex CAN network system. How to ensure the reliability, transmission rate, and fault tolerance between the control...
