Controller Area Network (CAN) is widely used in automotive, especially in safety-related situation. The reliability and stability of CAN-based ECUs and the whole network have become major concern. Thus it is important to research the dynamic behavior of them after the errors take place. A special instrument with windows software called disturbance generator, which can configured to work in different trigger modes and disturbances modes to inject or simulate different physical failures and protocol defined errors to the CAN bus, is developed to meet the specific test requirements. The systems analysis, principle diagram and functional features of the CAN disturbances generator are described, and the hardware and software design of the disturbance generator are presented in detail as well. The test results showed in the paper demonstrate that the CAN disturbances generator is effective and reliable.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
