In above preferred embodiment:
First bus is vehicle body CAN network, and all nodes support " CAN wake-up " thereon, implements the management of OSEK straight-forward network,
All nodes by CAN exchange network management information form single logic box.Even if network is in close state, node
Local activation and local function can also be executed.Such as BCM (car body controller) is active, and shines its application program controlling
Bright function, and the every other node on network is all in sleep pattern at this time.
It is answered on other nodes as long as the software application on the controller of Local activation enters to need to send or receive in network
With the state of data, the first bus will be waken up, and logic box implementation will trigger.Logic box and its node participated in are in and wake up
State, until not needing to carry out using data transmission.
Second bus is power CAN network, in accordance with OSEK indirect network management, wakes up the second bus node using rigid line,
Hard signal state is waken up to be controlled by CIU (gateway).
When it is low for waking up hard signal level, controller stops network communication.However, controller, which is in, not to allow to close
State when, controller keep activation, and continue communication until reaching the local state that it can be closed.
When CIU detects wake-up signal, it will pass through to wake up rigid line and export high level and activate power CAN network.Wake-up signal
It include: 1, vehicle body CAN network state of activation；2, rigid line wake-up signal；3, internal timer function.
In addition, the dynamic mode signal that CIU detection VCU (entire car controller) issues, determines whether network needs in sharp
State living.In general, these signals, which are in " OFF " state and indicate that, to allow to close.
The wake request that OBC (charger) is issued:
OBC issues wake request to CIU by a wake-up rigid line, and it is (minimum which belongs to short pulse
It 100ms), is that OBC is exported when detecting charging gun insertion；When CIU is in sleep state, OBC wakes up gateway, then triggers
CIU activates network, and CIU at least maintains Wake on LAN 90 seconds after being waken up by OBC.If necessary to charge, into charge mode.If
It does not need to charge, more than 90 seconds, CIU may turn off network.
KL15 (power supply when vehicle " ON " shelves) relay is as wake source: CIU reads KL15 relay status, really
Network when KL15 relay passes through PEPS (keyless entry and one-key start module) " activation " is protected also to be synchronized to activate.

VCU is existed simultaneously in the signal forwarding on power CAN and chassis CAN, being responsible between two networks, but VCU is not necessarily to
Connecting base plate wakes up relay, because VCU receives the system power supply mode signal in power CAN network and the signal of CIU sending,
It can simulate such wake-up input.This mean that only power CAN network link be also activated in the case of, chassis
CAN network link can just be activated, and CIU is responsible for managing and starting the link between two networks.
Wherein network activation means to prevent network from closing using logical node, and network release means that network is allowed to close, but
Some other application logical node can prevent network from closing, and activation is forced to mean to force to wake up network when network not yet activates.

Disconnect " releasing network after signal, the also releasing network in dropout failure.
Use-case 4: by heat management system mode activation.CIU is when receiving non-" OFF " status signal of heat management system mode
Holding vehicle body and power network activation, and the releasing network after receiving corresponding " OF " signal, are also released in dropout failure
Put network.
Use-case 5: switched by vehicle electric source modes and activated.Vehicle internal electric source management system becomes electric source modes from " OFF "
When for " ON ", PEPS output activation signal simultaneously activates KL15 relay, therefore all-network all forces activation under this state, to electricity
When source module is switched to " OFF ", PEPS exports release signal, releasing network.
Use-case 6: " Intelligent key electricity is low " reminds activation.PEPS is knowing Intelligent key low battery state and electric source modes
It is switched to " OFF " state from " ON ", PEPS keeps vehicle body network to activate and export " Intelligent key electricity is low " signal to IPC (group
Close instrument), " Intelligent key electricity is low " is provided to driver and reminds project, and after internal time-out 10 seconds, PEPS is by caution signal
