Normal fusing, so that protection circuit is safe, vehicle power supply point is related to reliability, relevant laws and regulations and the electromagnetic interference etc. that user uses
Factor.In real vehicle in use, the phenomenon that fuse melting also happens occasionally, after there is fuse melting, corresponding electrical function will
How failure reduces termination of insurance status to vehicle using bring inconvenience to the maximum extent, is the core of vehicle power distribution.
In the selection of power distribution, it is impossible to which each electrical appliance protects its connection line using an insurance
Shield, so in practical applications, different electrical appliances can be taken to share the strategy of insurance.User's vehicle is given in termination of insurance status in order to prevent
Bring is inconvenient, shares the strategy of insurance including but not limited to by functionally similar electrical appliance co-used insurance, or will safely compared with
Insurance is used alone in high electrical function, closes to vehicle to avoid the failure effect of other secondary functions and weighs the normal work of electric appliance
Make.These allocation strategies provide good guarantee for the safe handling of vehicle.CN204623369U discloses a kind of " automobile electricity
Source distribution system ", including battery, nose cabin electrical equipment box and indoor electric appliance box, battery include the first output end and the second output
End；Nose cabin electrical equipment box is electrically connected respectively at the first output end and the first subsystem, and the first subsystem includes that at least two first electricity consumptions are set
Standby, the first electrical equipment power is greater than or equal to preset value, and each first electrical equipment is in series with a fuse, at least one respectively
A first electrical equipment is connected with the first relay；Indoor electric appliance box is electrically connected with second output terminal and the second subsystem respectively, and second
Subsystem includes at least two second electrical equipments, and the second electrical equipment power is less than preset value, each second electrical equipment point
It is not in series with a fuse, at least one second electrical equipment is connected with the second relay.Its automobile power source provided distributes system
Each electrical equipment is connect a fuse by system, and electrical equipment power difference uses different relays, guarantees system stability
And safety.
Vehicle power distribution strategy at this stage has conducted a thorough research vehicle electrical appliance and line security, but for
For power supply supplier's generator under vehicle operating status, fail safe strategy then consider it is less, when generator or power generation
After machine circuit failure leads to fuse melting, the power supply supplier of vehicle only leans on battery, and the electricity of battery how to be allowed to play
Maximum effect, to the safety that raising vehicle uses, and to the maximum extent, reduction user loss has great meaning.
Summary of the invention
The purpose of the utility model is to provide a kind of vehicle power distribution systems, have both been able to achieve to generator and generator
The normal protection of route, and the service efficiency of accumulator electric-quantity can be improved, it, can be maximum especially after generator powered failure
Reduce to limit user's loss.
The utility model is divided into traveling basic training based on traditional vehicle power distribution strategy, by vehicle electricity consumption functional circuit
It can electric appliance and safety and comfort functional circuit two major classes.The utility model is by generator insurance setting in traveling basic function and safety
Between comfortable function, and travels basic function and be directly connected to battery feed.
A kind of vehicle power distribution system described in the utility model, including generator, the electric power storage with power generation mechatronics
Pond, the starting motor being electrically connected with battery, it is characterized in that: traveling basic function electric appliance and safety and comfort function electricity on automobile
Device is connected in parallel on the outlet line of the generator and battery；One generator insures the outlet line for being connected on the generator
On, and between the traveling basic function electric appliance and safety and comfort functional circuit.
Further, the traveling basic function electric appliance include engine EMS, ignition coil, atomizer, Oil pump electrical machinery,
Must be used in the driving processes such as TCU, ESP, EPS, gateway, brake switch, shift control assembly engine operation, braking,
It turns to, gearshift function.
Further, the safety and comfort functional circuit includes car body controller, glass lifting motor, front and back windscreen wiper, air-conditioning
System, reversing radar controller, panorama controller, lighting system, DVD entertainment systems, seat heating ventilation, lights a cigarette at rear defrosting
Function necessary to the non-vehicle such as device, electric horn, air bag are mobile.
The utility model has the beneficial effects that there is event in the power supply supplier generator or its route worked as under vehicle operating status
After barrier leads to fuse melting, battery can persistently provide power supply for traveling basic function, and safety and comfort function and battery
Between due to by insurance connection, after fuse melting, safety and comfort function cannot then be used because lacking power supply.It is this
The electricity consumed by reducing safety and comfort function, and increase the supply of traveling basic function electricity, it can be improved vehicle and exist
Mileage after generator insurance damage, allows vehicle driver to reach nearest safety area or maintenace point to the maximum extent.
Detailed description of the invention
Fig. 1 is traditional vehicle power distribution schematic diagram；
Fig. 2 is the vehicle power distribution schematic diagram of the utility model.
In figure: 1-traveling basic function electric appliance, 2-safety and comfort functional circuits, the insurance of 3-generators；10-power generations
