Abstract

The invention discloses a bus network management method, a bus network management system and a vehicle. The bus network comprises a CAN node and a CANFD node, and the method comprises the steps that when it is determined that the CANFD node has a CANFD network communication requirement, the CANFD node controls the CAN node to enter a sleep mode and controls the CANFD node to enter a CANFD communication state based on a mode of stopping sending a network management message; when it is determined that the CANFD node does not have the CANFD network communication requirement and has the CAN network communication requirement, the CANFD node starts to send a network management message; and when receiving the network management message sent by the CANFD node, the CAN node is awakened and enters aCAN communication state. The method can solve the problem that the coexistence of the CAN node and the CANFD node of the node on the bus network cannot be realized in the prior art.

Description

technical field [0001] The present application relates to the technical field of vehicle communication, and in particular to a bus network management method, a bus network management system, a vehicle and a computer-readable storage medium. Background technique [0002] At present, the traditional CAN (Controller Area Network, controller area network) network is upgraded to the CANFD (CAN with Flexible Data-Rate, CAN with flexible data rate) network. Due to the inconsistent frame format, CANFD nodes can normally send and receive traditional CAN reports. text and CAN FD messages, but traditional CAN nodes cannot send and receive CAN FD messages normally. This is because a traditional CAN node will report an error when receiving a CAN FD message. In the prior art, it is impossible to realize the coexistence of CAN nodes and CAN FD nodes in nodes on a bus network. Contents of the invention [0003] The purpose of this application is to solve one of the above-mentioned techni...
