Abstract

The invention relates to a gateway automatic test system of a CAN network, comprising a processor module; a CAN network module comprising two or more than two CAN bus systems for simulating the CAN network system of a vehicle; a gateway module to be tested for communication between the two or more than two CAN bus systems; a power supply control module for simulating the real vehicle ignition voltage change of the vehicle; and a switch control module for simulating the real vehicle ignition switching operation of the vehicle. The processor module is respectively connected to the CAN network module, the power supply control module and the switch control module; the CAN network module and the switch control module are connected to the gateway module to be tested; the processor module is used for selecting a test case so as to test the gateway module to be tested, analyzing a test result and outputting a test report. The gateway automatic test system of the CAN network of the invention is featured by simple and convenient operation, complete test, high test precision and high efficiency.

Description

technical field [0001] The invention relates to the technical field of automotive electronics, in particular to a CAN network gateway automatic test system and method. Background technique [0002] Due to the increasingly powerful functions of the vehicle control network, a large amount of quantitative information is required to be effectively transmitted on different CAN buses. Due to the repetition rate of the signal and the amount of data generated, the CAN bus system is divided into two or more CAN bus areas, such as CAN drive bus area (high speed), CAN comfort bus area (low speed), CAN instrument bus area ( low speed), etc. All the control units of each CAN system are connected in parallel on the CAN data bus, and the data exchange between the control units is completed through the CAN data bus. These data may be engine speed, fuel tank oil level and vehicle speed. [0003] Since different CAN bus areas have different communication standards, such as different transmi...
