Electric automobile comprises the first controller and second controller.First controller can be in multiple controllers of electric automobile except entire car controller arbitrary controller, second controller can be the arbitrary controller except entire car controller and the first controller.First controller and second controller can be the controllers of some function for performing electric automobile, such as, can be air-conditioner controllers, car body control module (BCM), VSC (ESP) and battery controller etc.Controller can comprise two states, wake-up states and resting state, and wherein, the controller be under resting state can perform the function of this controller after being woken.Electric automobile can comprise multiple controller, multiple controller is connected by CAN network bus, multiple controller comprises entire car controller, the first controller and second controller, also other controllers can be comprised, wherein, entire car controller for detecting the whole vehicle state of electric automobile, and sends whole vehicle state message by CAN network bus, and entire car controller can be periodically detect whole vehicle state and send whole vehicle state message.
First controller receives the information of outside input, obtains the first input information aggregate.The information of outside input comprises signal or the message of the outside input that controller receives, this input information can be the network management message except the first controller transmission in the multiple controllers by electric automobile, the message of the network management message preset format that to be arbitrary controller in the controller of electric automobile send at wake-up states, there is preset format, first controller judges whether to receive network management message, the network management message that first controller receives is the message that the controller in electric automobile except the first controller sends, can be judged by the CAN transceiver of self configuration, this CAN transceiver be may be used for detecting in CAN network the message that transmits and is filtered by the information of hardware to message, such as, CAN transceiver can be the CAN transceiver of TJA1042 for the model at grace intelligence Pu, do not need to wake controller up and filtration identification is carried out to message, also can be the whole vehicle state message that entire car controller sends, whole vehicle state message be the message generated after entire car controller detects the whole vehicle state of electric automobile, for reporting whole vehicle state, also can be electric source modes signal, electric source modes signal be the status signal of the electric source modes of electric automobile, and electric source modes signal comprises unlatching (ON) and closes (OFF), also can be local event, local event be the switching manipulation that user performs electric automobile, and such as, user opens air-conditioning in electric automobile.Wherein, local event and electric source modes signal can be hard signal, are lasting signals.First input information aggregate is the set of all external input informations that the first controller is currently received, and the first controller often receives an external input information, upgrades one time first input information aggregate.
Step S202, the first controller judges whether satisfied first wake-up condition according to the first input information aggregate.
After obtaining the first input information aggregate, judge whether the first controller meets the first wake-up condition according to the first input information aggregate.Alternatively, the first controller can receive the combination of multiple external input information, by the combination of multiple external input information as judging whether the first controller enters the condition of wake-up states.First wake-up condition can comprise the combination of multiple external input information, such as, the wake-up condition of air-conditioner controller can be enter wake-up states after receiving local event, or judge to input information aggregate be receive electric source modes signal be ON and other controllers send wake the network management message of air-conditioner controller up after, enter wake-up states, also namely the wake-up condition of air-conditioner controller comprises two kinds of modes, first kind of way only needs local event to wake up, it is that the network management message waking air-conditioner controller up that ON and other controllers send just can wake up that the second way needs to receive electric source modes signal.Alternatively, if the first controller only can accept a kind of external input information, satisfied first wake-up condition can be judged whether according to this external input information.
Whole vehicle state message is the message generated after entire car controller detects the whole vehicle state of electric automobile, for reporting whole vehicle state, preferably, when the information of outside input comprises whole vehicle state message, after the first controller receives whole vehicle state message, according to whole vehicle state message, first controller judges that electric automobile is the need of waking the first controller up under whole vehicle state: if the first controller needs to wake the first controller up under judging whole vehicle state according to whole vehicle state message, judge whether satisfied first wake-up condition, if meet the first wake-up condition of the first controller, enter wake-up states, if the first controller does not need to wake the first controller up under judging whole vehicle state, can determine that the first controller does not meet the first wake-up condition.
Preferably, when the information of outside input comprises whole vehicle state message, after the first controller receives whole vehicle state message, first controller judges whether according to whole vehicle state message the condition meeting the first forbidden energy pattern that enters, if the condition meeting the first forbidden energy pattern that enters judged by the first controller, enter the first forbidden energy pattern, wherein, the first forbidden energy pattern is used for forbidding that the first controller enters wake-up states.For example, whole vehicle state can be divided into: power on, and awaits orders, driving, lower electricity, fills, trickle charge soon, write with a brush dipped in Chinese ink the state such as program and fault, when charged state, can forbid that air-conditioner controller enters wake-up states, because the charging interval of electric automobile is usually much larger than running time, entering forbidden energy pattern by controlling some controllers in the charge state, the useful life of controller can be extended.
Preferably, the packets of information includes network administrative message of outside input, network management message carries and needs to wake controller identifier up, controller identifier to be waken up needs the controller waken up for the controller notifying to send network management message, wherein, after the first controller receiving network managing message, first controller judges whether controller identifier to be waken up comprises the mark of the first controller: if the first controller judges that controller identifier to be waken up comprises the mark of the first controller, judge whether satisfied first wake-up condition, if meet the first wake-up condition of the first controller, enter wake-up states, if the first controller judges that controller identifier to be waken up does not comprise the mark of the first controller, can determine that the first controller does not meet the first wake-up condition.
Step S203, if satisfied first wake-up condition judged by the first controller, enters wake-up states.
If satisfied first wake-up condition judged by the first controller, enter wake-up states.Alternatively, the first wake-up condition can comprise multiple wake-up mode.Preferably, when the information of outside input comprises whole vehicle state message, after the first controller receives whole vehicle state message, first controller judges whether according to whole vehicle state message to meet the condition entering the first half functional modes, if the first controller is judged to meet the condition entering the first half functional modes, enter the first half functional modes, wherein, the first half functional modes are used for the first preset function forbidding the first controller after the first controller enters wake-up states.
Alternatively, whole vehicle state can comprise charged state, after the first controller judges to receive whole vehicle state message, judge whether whole vehicle state is charged state according to whole vehicle state message, when judging that whole vehicle state is charged state, select to enter normal mode, the first half functional mode or the first forbidden energy patterns.Fig. 3 is the schematic diagram of the car load charged state of electrical vehicle network management method according to a first embodiment of the present invention.As shown in Figure 3, the controller except entire car controller, when judging that whole vehicle state is charged state, is selected to enter normal mode, half functional mode and forbidden energy pattern.For the first controller, if select to enter normal mode, the first controller, when meeting the first wake-up condition, can enter wake-up states and function is normal; If select to enter half functional mode, the first controller, when meeting the first wake-up condition, can enter wake-up states, but some function of forbidding the first controller self, the function of forbidding can be selected in advance; If select to enter forbidden energy pattern, the first controller, when meeting the first wake-up condition, cannot enter wake-up states.
Preferably, judge satisfied first wake-up condition at the first controller, after entering wake-up states, the first controller judges whether to need to wake other controllers up; If the first controller is judged to need to wake other controllers up, send network management message by CAN network bus according to the first prefixed time interval, network management message is the message of preset format.

Step S205, second controller judges whether satisfied second wake-up condition according to the second input information aggregate, and wherein, the first wake-up condition is different with the second wake-up condition.
According to the second input information aggregate, second controller judges whether that the method for satisfied second wake-up condition inputs information aggregate to the first controller according to first and judges whether that the method for satisfied first wake-up condition is similar, do not repeat them here.
It should be noted that, the wake-up condition of the first controller and second controller is different.Specifically, the first wake-up condition and the wake-up mode that the second wake-up condition comprises have at least a kind of is different.Such as, the wake-up condition of air-conditioner controller is when judging to receive local event, or, judging that electric source modes signal is ON, and receive other controllers send wake the network management message of air-conditioner controller up time, enter wake-up states, the wake-up condition of car body control module is when judging to receive local event, or, judging that electric source modes signal is ON, and receive that entire car controller sends wake the whole vehicle state message of car body control module up time, enter wake-up states, so, the wake-up condition of air-conditioner controller is different from the wake-up condition of car body control module.Electric automobile in the present invention is except entire car controller, the first controller and second controller, other controllers can also be comprised, the wake-up condition of other controllers can be identical with the first controller or second controller, also can be other wake-up condition, different from the wake-up condition of the first controller and second controller.The wake-up condition of other controllers is determined according to the concrete condition of controller, and the wake-up condition of the embodiment of the present invention to other controllers does not limit.
Whole vehicle state message is the message generated after entire car controller detects the whole vehicle state of electric automobile, for reporting whole vehicle state, preferably, when the information of outside input comprises whole vehicle state message, after second controller receives whole vehicle state message, according to whole vehicle state message, second controller judges that electric automobile is the need of waking second controller up under whole vehicle state: if second controller needs to wake second controller up under judging whole vehicle state according to whole vehicle state message, judge whether satisfied second wake-up condition, if meet the second wake-up condition of second controller, enter wake-up states, if second controller does not need to wake second controller up under judging whole vehicle state, can determine that second controller does not meet the second wake-up condition.
Preferably, when the information of outside input comprises whole vehicle state message, after second controller receives whole vehicle state message, second controller judges whether according to whole vehicle state message the condition meeting the second forbidden energy pattern that enters, if second controller judges the condition meeting the second forbidden energy pattern that enters, enter the second forbidden energy pattern, wherein, the second forbidden energy pattern is used for forbidding that second controller enters wake-up states.
Preferably, the packets of information includes network administrative message of outside input, network management message carries and needs to wake controller identifier up, controller identifier to be waken up needs the controller waken up for the controller notifying to send network management message, wherein, after second controller receiving network managing message, second controller judges whether controller identifier to be waken up comprises the mark of second controller: if second controller judges that controller identifier to be waken up comprises the mark of second controller, judge whether satisfied second wake-up condition, if meet the second wake-up condition of second controller, enter wake-up states, if second controller judges that controller identifier to be waken up does not comprise the mark of second controller, can determine that second controller does not meet the second wake-up condition.
Step S206, if second controller judges satisfied second wake-up condition, enters wake-up states.
If second controller judges satisfied second wake-up condition, enter wake-up states.Alternatively, the second wake-up condition can comprise multiple wake-up mode.Preferably, when the information of outside input comprises whole vehicle state message, after second controller receives whole vehicle state message, second controller judges whether according to whole vehicle state message to meet the condition entering the second half functional modes, if second controller is judged to meet the condition entering the second half functional modes, enter the second half functional modes, wherein, the second half functional modes are used for the second preset function forbidding second controller after second controller enters wake-up states.
