When a KL30 node based on AUTOSAR network management definition is in a non-power-on state, after the KL30 node is powered on, the KL30 node enters a bus sleep mode; the method comprises the following steps: after entering a bus sleep mode, receiving a network request or successfully receiving a network management frame, entering a repeated message sending state of a network mode, and starting a TREPEATMESSAGE timer and a TNMTIMEROUT timer in the stage; after entering a repeated message sending state, when the TREPEATMESSAGE timer is overtime and a network request exists, entering a normal execution state, and when the TREPEATMESSAGE timer is overtime and the network is released, entering a ready dormant state; and no matter which link of the network state is in, once the TNMTIMEROUT is overtime, entering a pre-sleep mode, starting a TWAITBUSSLEEP timer, and when the TWAITBUSSLEEP timer is overtime, returning to a bus sleep mode. According to the novel sleep wake-up strategy, the time and nodes of network wake-up of the whole vehicle are reduced, the power consumption of the whole vehicle is reduced, and the problem of power shortage faults of the whole vehicle is reduced.
本发明公开了一种低功耗高鲁棒性的整车休眠唤醒策略当基于AUTOSAR网络管理定义的KL30节点处于未上电状态时,接通其常电后,节点进入总线休眠模式;当进入总线休眠模式后接受网络请求或是成功接收网络管理帧后,进入网络模式的重复报文发送状态,该阶段会启动TREPEAT_MESSAGE定时器与TNM_TIMEROUT定时器;当进入重复报文发送状态后,当TREPEAT_MESSAGE定时器超时并且有网络请求时进入正常执行状态,当TREPEAT_MESSAGE定时器超时并且网络释放时进入就绪休眠状态;无论在网络状态的哪个环节,一旦TNM_TIMEROUT超时,则进入预休眠模式,并启动TWAIT_BUS_SLEEP定时器,当TWAIT_BUS_SLEEP定时器超时时,回到总线休眠模式。本发明新型休眠唤醒策略减少了整车网络唤醒的时间和节点,降低了整车电量消耗,减少了整车亏电故障问题的发生。
