Abstract: In order to solve the problems in EMI test of new energy vehicles such as low degree of intelligence, numerous flow, large programming quantity under multiple tasks and lack of flexibility, according to system requirements and through functional analysis, it is proposed to develop a characteristic frequency scanning system of EMI for new energy vehicles based on finite state machine, establish a mathematical model of the finite state machine and conduct reachability analysis for the model with HIPS software. The results show that the use of the finite state model for the characteristic frequency scanning system can realize reachability and improve the response speed of the system effectively.
