A CAN Bus Automatic Test System

In order to ensure the quality and stability on the CAN bus products,an automatic test system for CAN bus conformance testing is introduced, which allows the tester to execute the test validation automatically. CAN bus test module, test programs and some special test tools constitute the test system. All of the physical layer testing, data link layer testing, robust testing and communication testing are supported by the test system. Finally, this paper verifies the feasibility and functional integrity of the test system.
