His embodiment, belongs to the scope of protection of the invention.
Embodiment 1
The present embodiment provides a kind of automobile storage battery preventing electric loss guard method, and this method can be applied to engine and move
The fuel cell electric vehicle and hybrid vehicle of power battery, avoid electric automobile and stand for a long time so that battery loses
The problem of conductance causes vehicle not start.Specifically, the as shown in figure 1, automobile storage battery preventing electric loss guard method of the present embodiment
Comprise the following steps：
S101：Judge whether vehicle's current condition is locking resting state, if vehicle's current condition is locking resting state
Then enter step S102.
It should be noted that the locking resting state of vehicle is in static condition for engine stop operation, vehicle.
S102：Whether current batteries are judged in power shortage state is treated, if current batteries, which are in, is treated power shortage state
Then enter step S103.
It should be noted that the present embodiment according to batteries electricity from more to less by the whole state of batteries point
For normal condition, power shortage state and power shortage state are treated, treats that power shortage state can be understood as the critical power shortage state of batteries, is surpassed
The critical power shortage state is crossed, batteries are put into power shortage state.
As a preferred embodiment, described judge whether current batteries are following in treating that power shortage state passes through
Mode is realized：Judge whether the state-of-charge SOC of current batteries is less than first threshold, if the charged shape of current batteries
State SOC is less than first threshold, then the batteries are in and treat power shortage state.
The capacity that state-of-charge SOC accounts for batteries fully charged state for the currently owned electricity of batteries is big
Small, it indicates the dump energy of batteries.First threshold is default state-of-charge SOC value, if current state-of-charge

If the current gear positions of vehicle do not terminate to run in P gears or N gears, engine.
Due to when the gear of vehicle is located at P gears (Park) or N gears (neutral), the accidental movement of vehicle can be prevented.
This step is by confirming whether the gear positions of vehicle keep off (Park) in P or N keeps off (neutral), so as to ensure subsequently sending out
When motivation starts, vehicle will not change the current state i.e. static condition of vehicle.
Due to this step vehicle's current condition be locking resting state on the premise of trigger, and now car owner often from
Drive, during in order to prevent subsequent engine automatic start, have the danger of theft, in one embodiment, detection
Whether the current gear positions of vehicle are locked in P gears or N gears, if the current gear positions of vehicle are locked in P gears or N gears, enter
Enter step S104, in the embodiment when gear positions be locked in P gear or N keep off when, could only be unlocked by car key, i.e., without
When car key unlocks, the gear positions of vehicle can not be changed.
S104：Judge whether current engine fuel amount is more than or equal to preset value, if current engine fuel amount is big
In equal to preset value, then into step S105.
If current engine fuel amount is less than preset value, engine terminates to run.
It should be noted that the preset value of this step is the minimal amount of fuel required for engine start, when engine fires
When doses is more than or equal to preset value, it can be ensured that the normal startup of engine.
In one embodiment, current engine fuel is judged by detecting the fuel level of fuel tank highly
Amount, in this embodiment, the minimum fuel level height institute of fuel tank when preset value is ensures that engine can be enlightened normally
Corresponding fuel quantity.
S105：Start engine with to the battery charging.
After engine start, vehicle is idle in the lockout condition, and the operating of engine drives generator operation, so as to
Charging supplement is carried out to batteries.
The present embodiment is by detecting the power shortage state of batteries in vehicle locking resting state and triggering engine automatically
Start, so that vehicle runs a period of time in engine idle conditions, to the battery charging of vehicle, work as batteries
Closing engine is automatically controlled when charging to a certain extent.It can only be used relative to the startup of automobile engine of the prior art
Key operation realizes that the present invention, which realizes, can realize the function of starting engine automatically without key, make vehicle more intelligence
Energyization, avoid because vehicle for a long time stand storage and caused by discharged or defective battery problem, ensure that vehicle is shelved for a long time and remain to just
Often start, eliminate the pain that car owner waits for rescue by vehicle power shortage.In addition, the present invention also effectively extends the use of battery
Life-span.

N is kept off, then into step S204.
If the current gear positions of vehicle do not terminate to run in P gears or N gears, engine.
Due to when the gear of vehicle is located at P gears (Park) or N gears (neutral), the accidental movement of vehicle can be prevented.
This step is by confirming whether the gear positions of vehicle keep off (Park) in P or N keeps off (neutral), so as to ensure subsequently sending out
When motivation starts, vehicle will not change the current state i.e. static condition of vehicle.
Due to this step vehicle's current condition be locking resting state on the premise of trigger, and now car owner often from
Drive, during in order to prevent subsequent engine automatic start, have the danger of theft, in one embodiment, judge
Whether the current gear positions of vehicle are locked in P gears or N gears, if the current gear positions of vehicle are locked in P gears or N gears, enter
Enter step S104, in the embodiment when gear positions be locked in P gear or N keep off when, could only be unlocked by car key, i.e., without
When car key unlocks, the gear positions of vehicle can not be changed.
S204：Judge whether current engine fuel amount is more than or equal to preset value, if current engine fuel amount is big
In equal to preset value, then into step S205.
If current engine fuel amount is less than preset value, engine terminates to run.
