Vehicle network management method and system, and vehicle

Abstract

The present invention discloses a vehicle network management method. The method comprises the steps of acquiring a current network management state of a self-control node; acquiring a line state signal of the self-control node and line state signals of other predetermined control nodes; comparing the obtained line state signals and the current network management state with a predetermined state condition, and determining a desired network management state of the self-control node according to a comparison result; and controlling the self-control node to execute corresponding desired network management state logic. According to the method, each control node automatically determines, according to obtained state information, the desired network management state of the control node and adjusting corresponding desired network management state, so that the control node can be in a low power consumption state when in a sleep mode, and the control node can be awaken timely when the control node is to work. The development limitation of the control node due to use of a logic ring is broken up. The present invention further discloses a vehicle network management system and a vehicle. The system and the vehicle have the above beneficial effects.

Description

technical field [0001] The invention relates to the technical field of vehicle engineering, in particular to a vehicle network management method, system and vehicle. Background technique [0002] As the functional complexity of the vehicle is getting higher and higher, the number of ECUs (Electronic Control Units, electronic control units) is gradually increasing, and different ECUs have different requirements for power. The ECU is always in the wake-up state, which will increase the power consumption of the vehicle. Therefore, it is necessary to control the sleep wake-up of the constant power ECU through network management. However, the traditional OSEK network management requires a specific logic loop to control the sleep and wake-up of the network, and the ECU needs to be standardized, which makes development difficult and costly. Therefore, it is a technical problem to be solved by those skilled in the art how to conveniently realize the flexible state transition of th...
