Detailed description of the invention
The invention discloses a kind of automobile dynamic system, to reduce the unnecessary energy loss of vehicle, save the energy.The invention also discloses a kind of commercial vehicle/comm..vehicle with above-mentioned automobile dynamic system.
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiment.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1, the structural representation of the automobile dynamic system that Fig. 1 embodiment of the present invention provides.
Automobile dynamic system provided by the invention, comprises sustainer, main engine 1, power-transfer clutch 2, change speed gear box 3, the first electrical generator 4, sustainer, main engine control unit 14, storage battery 15, power assembly controller 12, donkey engine 10, donkey engine control unit 13 and the second electrical generator 11.Wherein, sustainer, main engine 1 is for driving dynamics is provided, and power-transfer clutch 2 is connected with sustainer, main engine 1 successively with change speed gear box 3, for the moment of torsion of sustainer, main engine 1 is spread out of.The first electrical generator 4 is connected with sustainer, main engine 1, and storage battery 15 is connected with the first electrical generator 4, drive by sustainer, main engine 1, by send out electrical power storage in storage battery 15.Sustainer, main engine control unit 14 is for starting sustainer, main engine 1, and power assembly controller 12 is by the break-make between the each consumer of Control and storage battery.The power of donkey engine 10 is less than the power of sustainer, main engine 1, donkey engine control unit 13 is for starting donkey engine 10, power assembly controller 12 is connected with sustainer, main engine control unit 14 and 13 communications of donkey engine control unit respectively, control the starting of sustainer, main engine 1 and donkey engine 10, the second electrical generator 11 is connected with donkey engine 10, this second electrical generator 11 is connected with storage battery 15, with by 11 of the second electrical generators electrical power storage in storage battery 15.
The present invention has designed the pattern of two driving engines (being sustainer, main engine 1 and donkey engine 10) collaborative works, sustainer, main engine 1 is high-power large-duty engine, and power when Vehicle Driving Cycle is provided is connected with sustainer, main engine 1 with change speed gear box 3 by power-transfer clutch 2, with transmitting torque, drive vehicle.The first electrical generator 4 is connected with sustainer, main engine 1, in the time that sustainer, main engine 1 is worked, provides electric energy, and accumulators 15 charges.Donkey engine 10, compared with sustainer, main engine 1, is small power motor, and the second electrical generator 11 is connected with donkey engine 10, and in the time that donkey engine 10 is worked, the second electrical generator 11 accumulators 15 charge.Sustainer, main engine control unit 14 and donkey engine control unit 13 have starting kinetic energy, can start by control engine, power assembly controller 12 is connected with sustainer, main engine control unit 14 and 13 communications of donkey engine control unit, is transmitted and is controlled sustainer, main engine 1 and donkey engine 10 and work by signal.The present invention is by lower-powered donkey engine 10 is set, without driving vehicle, while only driving annex work, can only start donkey engine 10, because the power of donkey engine 10 is less, therefore its energy resource consumption is lower, compared with prior art, it will save mass energy.
Sustainer, main engine 1 can be connected by gear or driving band with the first electrical generator 4, and corresponding, donkey engine 10 also can be connected by gear or driving band with the second electrical generator 11.Consumer generally comprises electronic cooling water pump 5, electronic fan 6, electric air-conditioning compressor 7, electric air compressor 8 and other consumers 9.By power assembly controller 12, can freely select energising and the power-off of electronic cooling water pump 5, electronic fan 6, electric air-conditioning compressor 7, electric air compressor 8 and other consumers 9.
In the time of sustainer, main engine 1 cold post-start, power assembly controller 12 disconnects being connected of electronic cooling water pump 5 and electronic fan 6 and power supply (power supply being herein the first electrical generator 4, the second electrical generator 11 and storage battery 15).During due to sustainer, main engine 1 cold post-start, the cooling water temperature of sustainer, main engine 1 is lower, for make sustainer, main engine 1 fast as far as possible complete warming-up process, after sustainer, main engine 1 cold post-start, first electronic cooling water pump 5 and electronic fan 6 are disconnected, in the time of sustainer, main engine 1 cold post-start, because its cooling water temperature is lower, without carrying out cooling by electronic cooling water pump 5 and electronic fan 6 to it.
In the time that the cooling water temperature of sustainer, main engine 1 exceedes preset temperature, power assembly controller 12 is controlled donkey engine 10 and is started.In the time of sustainer, main engine 1 cold post-start, owing to having cut off the power supply of electronic cooling water pump 5 and electronic fan 6, the cooling water temperature of sustainer, main engine 1 can rise rapidly, until reach preset temperature, this preset temperature is predefined temperature upper limit, power assembly controller 12 is controlled donkey engine 10 and is started, and drives electronic cooling water pump 5 and electronic fan 6 to work, so that the cooling water expansion tank of sustainer, main engine 1 is lowered the temperature by this donkey engine 10.Because auxiliary engine 10 power are less, drive electronic cold water pump 5 and electronic fan 6 to work by auxiliary engine 10, can relatively save a part of energy.
When vehicle is during in driving cycle, power assembly controller 12 is closed donkey engine 10.Due in driving cycle, travelling that to need sustainer, main engine 1 be vehicle provides power, and in order to save fuel oil, power assembly controller 12 is closed described donkey engine 10, is storage battery 15 power supplies by sustainer, main engine 1, drives each accessory equipment work.
When sustainer, main engine 1 is during in idling, power assembly controller 12 is closed sustainer, main engine 1 and is started donkey engine 10.Under idling mode, sustainer, main engine 1 is in idle running, and vehicle speed value is zero, now waits for operating mode in parking, and now sustainer, main engine does not drive Vehicle Driving Cycle, only drives consumer work.Now power assembly controller 12 is closed sustainer, main engine 1 and is started donkey engine 10, drives accessory equipment work by donkey engine 10, with respect to driving accessory equipment work by sustainer, main engine 1, can save a part of fuel oil.
At storage battery 15 undertensions, when battery supply feed, 12 of power assembly controllers can not start sustainer, main engine 1, only start donkey engine 10 accumulators 15 and charge.The present invention adopts lower-powered donkey engine 10 compared with direct employing sustainer, main engine 1, and himself loss is less, can greatly reduce the oil consumption of vehicle in real work.
In the time that vehicle-mounted air receiver air pressure is not enough, 12 of power assembly controllers can not start sustainer, main engine 1, only start donkey engine 10 to vehicle-mounted air receiver pressurization.The present invention adopts lower-powered donkey engine 10 compared with direct employing sustainer, main engine 1, and himself loss is less, can greatly reduce the oil consumption of vehicle in real work.
