Abstract
To address the complex challenges of modern new energy vehicles,such as low network transmission latency and high real-time data requirements,a vehicle gateway controller based on CAN FD(Controller Area Network Flexible Data-rate)was designed u-sing Renesas automotive-grade microcontroller RH850/F1 K.It features six bus channels,supports both classical CAN and CAN FD,and provides data storage.The bus transceiver employs the next-generation CAN transceiver TJA1462 to enhance signal transmission performance.The software design is based on the embedded operating system FreeRTOS,enabling multitasking and structured hierar-chical functions.Additionally,a specialized driver was developed for the CAN peripheral's unique transceiver method on the RH850/F1 K microcontroller.Using a USB-to-CAN tool,the gateway's data transmission and storage capabilities were tested.The results dem-onstrate that the designed gateway controller can operate smoothly even when the load rate approaches the bus usage limit,providing an efficient and reliable solution for vehicle gateway controllers.关键词
