Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described further:
As depicted in figs. 1 and 2, the present embodiment is described in detail the control of control recovery system of the present invention when being in various state:
1, the signal collector of storage battery, throttle, brake etc. is increased.Increase air-conditioning and generating and electrical motor change over controller.Electrical generator and storage battery may need to change to meet requirements at the higher level.2, monitor vehicle when being in acceleration mode: a, as air-conditioning is in open mode, control air conditioner electric control power-transfer clutch, close air-conditioning compressor.Save the fuel engines power that air-conditioning takies.After acceleration mode stops (or other parameters occur), control air conditioner electric control power-transfer clutch, reopen air-conditioning compressor.This process does not affect air-conditioner air outlet air-out in car.B, the state of vehicle battery collected according to storage battery signal picker, control electrical generator and electrical motor change over controller, electrical generator be switched to electric motor state from generating state.While namely electrical generator no longer takies fuel engines power, follow procedure controls the Power output of electrical motor.Battery power is converted to vehicle power.C, we know that the power of equipment and moment of torsion and rotating speed are correlationship.The fuel engines of same chassis and the revolution ratio of electrical generator and air-conditioning compressor immobilize.Namely electrical generator is converted to the shared moment of torsion with discharging of electrical motor, and mitigation and amplification multiple is identical.
During the at the uniform velocity motoring condition of 3, stated limit: a, any control operation is not carried out to air-conditioning compressor.B, by storage battery signal picker, storage battery to be monitored, when only certain condition being met to storage battery, stop generator operation, with saving fuel oil, reduce energy consumption and the discharge of driving engine.4, when monitoring vehicle at brake deceleration: a, any control operation is not carried out to air-conditioning compressor.B, electrical generator must to battery charges, recovery section energy.
Run according to control system of the present invention, as shown in Figure 4: after tested, during vehicle acceleration, fuel engines rotating speed is between 1500-3000rpm usually, we calculate according to aviation value, by the step a programming control in above-mentioned control program 2, can be vehicle acceleration increase about 16 Ns of rice moments of torsion.By the step b programming control in above-mentioned control program 2, can be the moment of torsion of vehicle acceleration increase about 9 Ns of rice (previous status is consumption 4 Ns of rice, is now output 4 Ns of rice).Add up to the moment of torsion increasing about 25.2013, the parameter of 14 years global top ten's driving engine Subaru FA20 driving engines is: maximum power 148KW/7000rpm, torque peak 205 Ns of rice/6400rpm, calculate by native system by increasing the moment of torsion of torque peak about 12%, as increased more according to FA20 driving engine in the torque arithmetic of 2000rpm by this.
Shown in the engine power torque curve figure of Fig. 4, by common situations during vehicle acceleration, engine speed is elevated to 3000rpm from 1500rpm, and torsion increases 25-30 ox rice, due to the smart allocation that native system uses engine power, the highest driving torsion that can increase by 25 Ns of rice.Consider that vehicle may be in the reason such as non-using air-condition or battery power deficiency, drive torsion 12 Ns of rice to calculate by average increasing.Engine torsion will be reduced and export 40%, reduce exhaust emissions 40% simultaneously.
Data according to the relevent statistics, the situation such as acceleration, deceleration, startup of vehicle accounts for the 50-90% of total run time, and wherein accelerated condition accounts for 30-50%, and the 2-6 of driving engine when instantaneous oil consumption is about at the uniform velocity when accelerating doubly.Because the homogeneity of acceleration mode engine air in-cylinder mixture strength is damaged, combustion efficiency declines, and discharge increases higher.Native system is got involved when vehicle acceleration exhaust emissions several times increase, and reduces particle emission peak effect more obvious.
Detect the situation of vehicle exhaust emissions under different conditions, as shown in Figure 5: by the instantaneous the criterion of the fuel consumption of some vehicle existing, we also can see the oil consumption of vehicle at different conditions intuitively.Also just correspondence is the exhaust emissions of different conditions vehicle.Vehicle launch with when accelerating, corresponding index often vehicle corresponding index when at the uniform velocity travelling 2-8 doubly.If that is we start to walk frequently and accelerate, under the load conditions particularly blocked up now, emission from vehicles will be increased greatly, cause environmental pollution.And the moment of torsion that the present invention increases when accelerating will reduce the rotating speed of fuel engines, reduce exhaust emissions peak value when accelerating, protection of the environment.Reduce and cut down peak value exhaust emissions 40%.
