Abstract

The present application relates to an AUTOSAR-based local network management method and system. The method includes the steps of: constructing a network topology map of all ECUs; configuring a number of ECUs for each functional group according to the network topology map, and providing Set the priority; define the network management message, the network management message includes the status indication bits of all function groups, and assign the position of the status indicator bits of the function group in the network management message according to the priority of the function group ; When the function group triggers the activation condition, determine the response strategy according to the number, type and priority of the activated function group, the ECU identifies the network management message, and executes the wake-up or sleep operation according to the status indicator bit of the function group to which it belongs . The local network management method provided by the present application can reduce battery power consumption, save more energy, and prolong the life of the ECU.

Description

technical field [0001] The present application relates to the technical field of automotive electronics, in particular to an AUTOSAR-based local network management method and system. Background technique [0002] At present, the network management commonly used in automobiles is usually global network management, that is, when a certain function is activated, all ECUs (Electronic Control Units) on the network that participate in network management need to be woken up, even if some ECUs do not participate in this function activation. The work will also be woken up, causing the ECUs on the network to be in the wake-up state, which will cause the disadvantages of fast battery power consumption and shorten the life of the ECU. Contents of the invention [0003] The embodiment of the present application provides an AUTOSAR-based local network management method and system to solve the technical problems of fast battery power consumption and short ECU life in the related art. ...
