Operation of the electronic fan is stopped or reduced by means of detecting a power supply state, and a purpose of protecting storage batteries is achieved.
Description
Technical field
The invention belongs to vehicle control field.What the present invention relates to is a kind of method and system of controlling the cooling of vehicle motor radiator with electronic fan.Specifically, relate to and a kind ofly can when the cooling of control vehicle motor radiator is with electronic fan, protect the method and system of storage battery in the power supply line.
Background technique
Present vehicle is passenger vehicle particularly, much all is to use DENG, fuel-economizing to receive everybody generally attention.But, because having followed " the non-temperature control " of truck, its conventional engines radiator cooling system reaches " inoperative is Continuous Drive still " characteristics, these characteristics have determined the cooling system oil consumption high.Traditional concept " is not boiled " with water tank and is got final product, and motor often is lower than standard temperature, and the thermal efficiency is low, and fuel consume is high; When engine whole vehicle was used, " non-temperature control " made air inlet, entering water temp only relevant with engine speed, do not reach the optimum temperature of stand requirement.Temperature contrast causes the thermal efficiency low more greatly, and fuel consume is high.The cooling fan continuous running, consumed power still in the time of need not dispelling the heat causes the fuel oil waste.
In order to address these problems, improve the efficient of fuel oil, adopt the electronic fan controller to control the operation of fan now according to the temperature of motor, reach and overcome the purpose that " non-temperature control " reaches " inoperative is Continuous Drive still ".Fig. 1 is the schematic diagram of existing electronic fan radiation system, and motor 1 passes through the cooling water heat-shift with radiator (water tank) 2; Whether electronic fan controller 5 moves according to the temperature information decision electronic fan 3 of radiator (water tank) temperature transducer 4, carries out the heat radiation work of radiator (water tank); General DENG should keep the temperature of radiator (water tank) relatively good at 85 °～90 °; Power supply line's powered that electronic fan 3 is made up of generator 8 and storage battery 7, the solid line among the figure are represented power supply line's (so positive and negative two lines are arranged).This temperature control system can be controlled according to the temperature of radiator (water tank) 2, and when need not dispelling the heat, electronic fan is consumed energy not, and this had both practiced thrift the energy, also makes motor be in best operating temperature zone simultaneously, has improved the efficient of fuel oil.
But electronic fan 3 needs power consumption.In order to guarantee the normal electricity consumption of electronic fan, must make the generator of vehicle that corresponding electric current can fully be provided.Such as, originally the 150A generator that needs of passenger vehicle provides the system such as illumination, air-conditioning of passenger vehicle, and needs 60A during the electronic fan full speed operation, can only select the generator of 210A so for use, and this causes the bigger generator of purchase to cause waste.In addition, on the passenger vehicle that has dispatched from the factory, be exactly the 150A generator for preparing originally, will cause bigger waste if change.
So general way is exactly now, be the special generator that increases a 60A of electronic fan.Cost increases like this, and difficult installation.No matter some people is clear-cut the power demands that electronic fan increased in addition.In use, like also no problem.But say it is that problem is arranged certainly from reason, that is to say when generator 8 electricity shortages, the electricity that uses storage battery 7 is replenished.Storage battery 7 will often be in the state that discharges and recharges like this, and this infringement to storage battery 7 is very big, has a strong impact on the working life of storage battery 7
The consumer of passenger vehicle has now: illumination and supplementary equipment (the inside and outside lighting burner of vehicle, TV and sound equipment, electronics station reporting instrument (electric sign board) electric heating diversion machine), air conditioning appliance equipment (condenser fan and evaporator fan) and special equipment (electric eddy current retarder, ABS and ECU control module).When the design passenger vehicle; Generally defer to the idling matching principle-since air-conditioned passenger train under any driving cycle, all to use air-conditioning; And; Urban public traffic vehicles accounts for more than 70% of whole running process in the operating mode that waits with middle low cruise, and the electric current that therefore needs generator to export must satisfy the needs of vehicle air conditioning and other main consumer, idling that Here it is coupling.
We see an instance of specifically selecting generators of passenger cars for use; All electric consumers that at first will be except that air-conditioning and warm braw; Comprise car light, TV, water heater, wiper, the power consumption addition of electric eddy current retarder, wherein the power consumption of electric eddy current retarder is 100A; But consider that it does not work long hours, make even equal power consumption 50A. then the electricity consumption data of vehicle be:
I1 vehicle power consumption (not containing air-conditioning and the warm braw)=about 30A=80A of other electric consumers of electric eddy current retarder 50A+
I2 idle call electric weight=70A
I3 warm braw power consumption=20A
The I4 idling mode is the power consumption=80A of the main electric consumer of work (after this moment, considered was used electric eddy current retarder, storage battery was in the power shortage state, for guaranteeing the proper functioning of retarder, needs generator to the timely quick charge of storage battery) down.
Because I1+I2=150A＞125A is so car load need use two generators.Wherein the no storage battery generator of a 8SC3110VC (24V-150A) is the air-conditioning system power supply; The adjustment velocity ratio, the output current that does not have the storage battery generator when making idling guarantees the needs of air-conditioning more than or equal to 70A (the idling output of 3110VC); And high workload rotating speed is no more than 8,000rpm; AC172R on the Cummins Engine (24V-140A) generator, under idling mode output current be about 110A >=I3+I4=100A, and high workload rotating speed is no more than 8,000rpm.
Obviously, select the instance of generator for use according to above-mentioned passenger vehicle.We know the power consumption of groundless increase electronic fan, must not meet the designing requirement of original passenger vehicle.But under a lot of situation, the output of generator is rich fully, and for example electric eddy current retarder 50A (100A during use) opposes with electronic fan at all.Reason is, when the driver touches on the brake, clearly is to need to reduce the speed of a motor vehicle, also can not give engine oil.So at this moment be exactly that electronic fan does not change, the temperature of motor can not be elevated to problematic degree yet.In other words during the electric eddy current retarder electricity consumption, electronic fan fully can not electricity consumption; Promptly can electronic fan and the electric eddy current retarder time-sharing multiplex take the power supply supply of this 50A jointly.
Summary of the invention
Owing to adopt electronic fan and the electric eddy current retarder time-sharing multiplex power supply period, so need knowing electric eddy current retarder, the electronic fan controller when is in user mode, whether decision closes the electricity consumption of electronic fan then.When obviously electric eddy current retarder uses, can detect driver's order (action), also can detect the working signal of electric eddy current retarder.But these detecting methods all are difficult to install.The essence of problem is that generator may not provide enough electric currents when electric eddy current retarder and electronic fan co-operation in fact, will inevitably cause the voltage of power supply line to descend like this.When voltage dropped to 24V, storage battery began external power supply, so so long as the voltage of power supply line drops to 24V must be electricity shortage just, Here it is stops correct opportunity of electronic fan work.
Can certainly detect the use electric current of electric eddy current retarder, when he is enough big, show that it starts working.So:
A kind of method of controlling the cooling of vehicle motor radiator with electronic fan, it comprises: the power supply state that obtains power supply line; When the electricity shortage of power supply line, controller control stops or minimizing work cooling with electronic fan;
Further, the power supply state that obtains power supply line is the voltage that detects in the power supply line, when voltage during less than rating value, is judged to be electricity shortage;
Insurance ground, rating value are 25V.
Alternatively, the power supply state that obtains power supply line is the output current that detects storage battery in the power supply line, when output current during greater than rating value, is judged to be electricity shortage;
Ordinary circumstance, vehicle motor are DENGs.
In addition, a kind of system that controls the engine radiator cooling with electronic fan, it comprises: radiator (water tank) temperature transducer; Radiator (water tank) heat transmission electronic fan; Storage battery; Generator; Detection part is used to detect power supply line's power supply state of being made up of storage battery and generator; The electronic fan controller;
Storage battery and generator are formed power supply line; When radiator (water tank) temperature transducer judge radiator (water tank) temperature reach impose a condition after; The control of electronic fan controller makes electronic fan work, uses the electricity of power supply line to carry out the heat radiation work of radiator (water tank); When detection part detected power supply line's electricity shortage, the control of electronic fan controller stopped electronic fan or minimizing work;
Ordinary circumstance, this system also has electric eddy current retarder.
