Description
Technical field
It the utility model is related to vehicle electric field, and in particular to automobile quiescent current monitors system.
Background technology
After automobile flameout parking, generator is stopped, and storage battery is as the unique power supply of full car, there is provided car during parking
The work of upper each electric component and standby current, and provide starting current for automobile starting next time.Under normal conditions, to keep away
Battery-free power shortage, stops working after parking, each electric component is in dormancy or holding state on automobile, only consumes small Static Electro
Stream（Both dark current）, so as to ensure that automobile can park longer time and is again started up without influencing.
But if there is some abnormal service conditions, such as body light does not close, the later stage arbitrarily installs electric appliance additional, quiescent current
It will be significantly increased, accelerate the consumption of storage battery, causing to park a period of time rear vehicle to start, and damages storage battery.Separately
Outside, if there is some failures, such as damage of line short, parts, electric leakage, manufacturer and user and it is ignorant in the case of,
Larger electric leakage quiescent current can cause discharged or defective battery, cause automobile not start, if being continuing with these larger leakages
Electric quiescent current parts, are likely to result in more parts damages, damage, or even trigger the major accidents such as vehicle fire.
Therefore, after automobile flameout, how effectively and uninterruptedly monitoring automobile quiescent current be that a needs solve
Problem.
Utility model content
The utility model discloses automobile quiescent current to monitor system, can uninterruptedly monitor automobile quiescent current.
Automobile quiescent current monitors system, it is characterised in that：Including storage battery, vehicle mounted electrical apparatus, quiescent current monitoring module,
Automobile ECU and sensor；
The vehicle mounted electrical apparatus, quiescent current monitoring module are connected in parallel on storage battery power supply circuit；
The sensor series are on storage battery power supply circuit；
The first current signal output end of the parallel setting of the sensor, the second electric current capacitance signal output terminal, described first
Current signal output end is connected by data cable with quiescent current monitoring module, and the second electric current capacitance signal output terminal passes through
Data cable is connected with automobile ECU.
Further, the Engine ECU of automobile ECU engine idling start and stop in order to control.
Further, first current signal output end is connected by LIN lines with quiescent current monitoring module, and described
Two electric current capacitance signal output terminals are by LIN lines with controlling the Engine ECU of engine idling start and stop to be connected.
Further, communications module, server and user terminal, the report of the quiescent current monitoring module are further included
Alert signal output part is connected by data cable with communications module by signal input terminal, and communications module by signal output terminal passes through
Wireless network is connected with server, and the server is connected by wireless network with user terminal.
The utility model advantageous effects are：
1）The storage battery signal monitoring of Double Data line, current signal sensor set two data lines respectively with automobile ECU,
Quiescent current monitoring module connects, and can be supervised respectively at the same time by automobile ECU, quiescent current monitoring module after engine misses
Survey storage battery capacitance information and quiescent current variation situation and do not interfere with each other mutually.Instantaneous in automobile flameout, automobile ECU needs to learn
After moment storage battery capacitance is so as to next engine start, compared with the storage battery capacitance monitored again, whether storage battery is judged
It can normally support automobile ECU controlled load case（The functions such as the start and stop of engine idling, intelligent automobile）, and due to cabin temperature mistake
Height, can not also slack off flame-out rear instant static curent change monitoring, it is desirable to which quiescent current monitoring module is to quiescent current
Start abnormal monitoring, tackle such Intelligent Control Strategy, set the Double Data line of the utility model to connect automobile ECU, static state
Current monitoring module scheme, realizes that quiescent current information is accurate, does not disturb quick reception and registration.
2）Independently of the additional static current monitoring and controlling modular structure of automobile ECU, since operating mode considers that automobile ECU is being sent out
A period of time after motivation is stopped working, will in a dormant state, and after engine misses, cabin temperature is high, quiescent current real time monitoring
The necessary frequent starting of mechanism, therefore independent separate goes out additional static current monitoring and controlling module and starts monitoring to quiescent current.
Brief description of the drawings
Fig. 1 monitors system schematic for quiescent current.
