Fuzzy Testing Method of CAN Bus of Charging Pile Based on Genetic Algorithm

Abstract

With the guidance of the new energy policy and the continuous expansion of the new energy market, electric vehicles are the development direction of the automotive industry in the future, and the electric vehicle charging infrastructure is an important guarantee for the use of electric vehicles, which plays a positive role in promoting the popularity of electric vehicles. CAN bus protocol is the communication protocol between charging pile and electric vehicle, and its security concerns the safety of electric vehicles. In this article, a CAN bus fuzzy testing method based on genetic algorithm is proposed to solve the security problem of charging pile CAN bus. In this method, genetic algorithm is added in the fuzzy testing process of CAN bus protocol, that is, genetic algorithm is introduced in the generation of fuzzy data to search the test case that best conforms to CAN bus protocol, so as to greatly improve the detection efficiency of CAN bus protocol.
