Abstract: This paper analyzes the development trend of special vehicle control system technology. The significance and problems of intelligent power distribution system research and development are summarized. Combined with practical application, the hardware architecture and system implementation of intelligent power distribution module are analyzed. By using electronic switches instead of relays and fuses, realized the intelligent power distribution and fault diagnosis function of the module. Controller Area Network (CAN) bus communication technology is used to communicate with the main system. The module meets the corresponding technical indicators and application requirements. The efficiency and safety performance of power distribution are optimized to a great extent. It has the characteristics of high intelligence, good maintainability and strong universality. The research and development of this module is also an important foundation for realizing unmanned driving in the future.
