Abstract

Because the throughput of the traditional wireless communication and positioning system of EVs is reduced, which can not meet the needs of users, the wireless communication and positioning system of EVs based on CAN bus is designed. Using the central control board to collect the real-time status, exchange information data, select the tps5430 switching power conversion chip to realize the two-way transmission with MCU address and data; under the support of hardware structure, optimize the initialization procedure, use the toa positioning principle to complete the positioning and ranging, extract the effective information, and realize the design of the wireless communication positioning system of the programmable electric vehicle based on CAN bus. Using computer simulation software, the performance of the system is tested. The results show that when the traffic load increases to 45mbps or higher, the throughput curve of the traditional system gradually shows a downward trend, while the throughput of the designed system does not change significantly after the traffic load increases, which can meet the needs of users.
