Fig. 2 is a kind of example flow diagram of vehicle-mounted weak electricity system control method according to some embodiments pair.
In step sl, the vehicle-state value before light-current system obtains the remaining capacity of battery and stops working.?
In some embodiments, vehicle-state value includes but is not limited to the electricity of Fuel Oil Remaining or power battery.The remaining capacity of battery
It can be used for subsequent judging whether to charge to battery with the vehicle-state value before flame-out.
In step s 2, compare battery remaining capacity and preset first given threshold,
In some embodiments, the remaining capacity and the first given threshold of light-current system comparison battery.Wherein institute
Stating the first given threshold is fixed threshold, when the remaining capacity of battery is greater than the first given threshold, shows the surplus of battery
Remaining electricity is sufficient；When the remaining capacity of battery is less than the first given threshold, demonstrate the need for charging to battery.One
In a little embodiments, the first given threshold can have factory settings, can also there is the self-service setting of car owner.For example, if the big portion of car owner
Divide the time of using cars in the higher area of temperature, then the first given threshold can be set slightly lower；If car owner largely uses vehicle
Time is in the lower area of temperature, then the first given threshold can be set slightly higher.In step s3, when the residue of battery
When electricity is less than preset first given threshold, vehicle-state value is sent to car owner.
In some embodiments, it when the remaining capacity of battery is less than the first given threshold, demonstrates the need for battery
It charges.But it also needs to be further determined whether according to vehicle-state value to charge to battery.
Specifically, if vehicle-state value is greater than the second preset threshold, illustrate Fuel Oil Remaining abundance, then battery is carried out
Charging, will not influence the starting and normal use of vehicle because charging a battery.Therefore light-current system can voluntarily give birth to
At charging instruction.
When the remaining capacity of battery is less than the first given threshold, and vehicle-state value is less than or equal to second and presets
Threshold value, can due to the remaining capacity of remaining amount of fuel and/or power battery in charging consumption fuel tank if charging to battery
It can influence the normal use of vehicle, it is therefore desirable to send reminder message to car owner, wait the control instruction of car owner.
It should be noted that normal use referred herein refers to, vehicle can be reached gas station's oiling by car owner.Car owner
The second preset threshold can be set according to use habit.For example, second is pre- if the place of parking is closer apart from gas station
If relatively low value can be set in threshold value, if parking place apart from gas station farther out, the second preset threshold setting
Relatively high value.When car owner receive Fuel Oil Remaining it is lower remind it is small when after, need are judged whether according to specific Fuel Oil Remaining
Start vehicle to charge to battery.If it is considered to charging will not influence the normal use of vehicle, then to light-current system
Charging instruction is sent, otherwise sends not charging instruction, or do not make any instruction.If car owner does not do any instruction,
Light-current system does not start vehicle to charge to battery.
In step s 4, control instruction is generated according to vehicle-state value.
In some embodiments, when vehicle is fuel vehicle, vehicle-state value refers to the oil mass value of fuel tank；When vehicle is electricity
When motor-car, vehicle-state value refers to the charge value of power battery；When vehicle is hybrid electric vehicle, vehicle-state value refers to fuel tank
Oil mass value and power battery charge value.
When vehicle-state value is greater than the second preset threshold, illustrate that Fuel Oil Remaining and/or remaining capacity are sufficient, vulnerabilities scan
System can voluntarily generate charging instruction.When vehicle-state value is less than or equal to the second preset threshold, receive from car owner's
Control instruction generates charging instruction according to the control instruction of car owner.In some embodiments, if the control instruction of car owner is to fill
Electricity, then light-current system generates charging instruction；If the control instruction of car owner is to forbid charging, light-current system is not generated
Charging instruction.
In step s 5, it is charged according to charging instruction to battery.
Specifically, when light-current system generates charging instruction, or the control according to car owner according to vehicle-state value oneself
When system instruction generates charging instruction, starts engine and/or motor and charge to battery.
In some the present embodiment, starts engine in light-current system and/or motor charges to battery
During, vehicle-state value is obtained in real time.If vehicle-state value is less than or equal to third predetermined threshold value, stop to battery
Charging.Third predetermined threshold value can may be the same or different with the second given threshold, as third predetermined threshold value is slightly smaller than
Two given thresholds.The purpose of third predetermined threshold value is set also for the residue electricity for preventing Fuel Oil Remaining and/or power battery
Amount is not enough to support the normal operation of vehicle.If vehicle-state value is less than or equal to third predetermined threshold value, light-current system
Stop charging, and send reminder message to car owner, waits the instruction of car owner.After car owner sees reminder message, make specific
Continue the instruction charged or do not charged, or does not do any instruction.After light-current system receives being explicitly indicated of car owner, execute
Car owner's is explicitly indicated.If light-current system does not receive being explicitly indicated for car owner, stop charging.
In some embodiments, during charging a battery, the charging current of battery is obtained in real time；According to storage
The charging current of battery judges whether to need to continue to charge.
Specifically, judge whether the current value of charging current is less than preset current threshold during the charging process, if so,
Stop charging to battery.In other words, the present embodiment is current value by charging current to determine whether stopping battery
Charging illustrates that the electricity of battery supports vulnerabilities scan enough if the current value of charging current is less than preset current threshold
The normal work of system continues to fill conversely, illustrating that the electricity of battery also is not enough to support the normal work of light-current system
Electricity.
In some embodiments, after battery completes charging, the current vehicle-state value of vehicle is sent into car owner, so as to
The remaining capacity of vehicle Fuel Oil Remaining or power battery can be understood in time in car owner.
In some embodiments, when starting engine charges to battery, vehicle only charges to battery,
Other vulnerabilities scan devices such as remaining function, such as not starting ignition, air-conditioning, headlight, sound equipment of vehicle are not started to reduce as far as possible
The power consumption of vehicle.
Vehicle-mounted weak electricity system control method provided in this embodiment, when the remaining capacity of battery is less than the first given threshold
When, vehicle-state value is sent to car owner, is then judged whether according to car owner's control instruction that vehicle-state value and car owner return
It charges to battery, this method can in time charge to the battery of vehicle, and car owner is avoided to forget and lead to electric power storage
Pond feed, the case where can not starting so as to avoid vehicle, and the problem of reduction service lifetime of accumulator；And it avoids not
It needs to charge to battery and start engine, reduces the frequency of engine start, improve the service life and dimension of engine
Protect cost.
The present embodiment also provides a kind of vehicle-mounted weak electricity system control device, as shown in figure 3, vehicle-mounted weak electricity system control device
