Embodiment
In order to be more clearly understood that the technology contents of the present invention, described in detail especially exemplified by following examples.It is it should be understood that real
Apply example and be only for the explanation present invention, rather than limitation of the present invention.
Fig. 1 be the present invention mixed power plant and the method accordingly controlled a specific embodiment involved by mixing move
The structural representation of power apparatus.Reference picture 1, described mixed power plant include：Engine 100, it includes belt pulley
It is 101；Gearbox 200, it includes main reducing gear gear wheel 201, has at least five forward gear；Dynamoelectric machine 300；Motor
Travelling gear 400, with the engaged transmission of main reducing gear gear wheel 201；First clutch 501, for connecting the dynamoelectric machine
300 with belt train 101；Second clutch 502, for connecting the dynamoelectric machine 300 and motor-driven gear
400。
The gearratio i of lower surface analysis motor-driven gear 400MSet.It is noted that iMFor motor-driven gear 400 and master
The resultant gear ratio realized after the engaged transmission of decelerator gear wheel 201.It is readily appreciated that, shifting power is compensated, vehicle electrical is wriggled and straight
Regenerative braking is connect for iMRequirement be different, therefore analyze these functions first to iMRequirement, then synthesis draw one
Suitable iM。
The data of economical A levels car are provided first, it is specific as follows to carry out calculating analysis：Vehicular gross combined weight
1500kg, tire radius 0.3m, the gearratio of 5 forward ranges of gearbox is respectively 3.583/1.947/1.343/0.976/
0.804, main step-down ratio is 4.052；The peak power of dynamoelectric machine 300 is 15kW, torque capacity 50Nm, highest
Working speed 18000rpm；Gearratio between engine and dynamoelectric machine is 1/3.
The gearratio i of motor-driven gear 400MAccording to following condition setting：
iM=inif/ibN=1,2,3,4,5 (1)
Wherein, inFor the forward gear ratios of gearbox, ifFor final driver ratio, ibFor engine and electronic/generating
Belt transmission ratio between machine.
When vehicle electrical is wriggled, vehicle wriggling is operated alone in dynamoelectric machine 300, and its torque request can be used on 5% slope
Road surface not back skating is spent to determine, so that it is determined that iM.Back skating torque on wheel is 225Nm, by the maximum of dynamoelectric machine 300
Torque 50Nm, i can be calculated according to formula (1)M=4.5, calculate in=0.37, therefore in＞ 0.37, then iM＞ 4.5, then electronic/hair
Motor 300 is enough to drive vehicle electrical to wriggle, that is, takes the gearratio of 4 gears before gearbox to substitute into obtained iMCan meet will
Ask.
When vehicle regenerative is braked, dynamoelectric machine 300 directly carries out energy regenerating.The max. speed of NEDC state of cyclic operations
For 120km/h, as long as therefore the energy regenerating more than 10kW is carried out in this vehicle speed range, then can be by the system more than 80%
Energy is recovered in battery.According to the highest working speed 18000rpm and speed 120km/h of dynamoelectric machine 300, according to
Formula (1) can calculate iM=17.0, calculate in=12.6, therefore in＜ 12.6, then iM＜ 17.0, then dynamoelectric machine 300 is sufficient
To carry out energy regenerating in 120km/h vehicle speed ranges, that is, the gearratio of 4 gears before gearbox is taken to substitute into obtained iMAll may be used
To meet to require.
During vehicle shift, dynamoelectric machine 300 carries out power compensation, to avoid power interruption.The running resistance work(of vehicle
Rate increases as speed increases, and the power compensation power demand under different speeds is different.One kind gearshift speed be：
20km/h changes 2 grades, and 40km/h changes third gear, and 60km/h changes 4 grades, and 80km/h changes 5 grades, and the resistance power in 80km/h is about
12kw, dynamoelectric machine 300 are enough to carry out power compensation to gearshift.If changing 5 grades in 120km/h, resistance power reaches
35kW, the power limited of dynamoelectric machine 300, therefore also need to engine 100 and Partial Power is provided.It can also now utilize
Vehicle reduces the rotating speed of engine 100, therefore the tension side rotating speed of first clutch 501 or second clutch 502 should be higher than that
The rotating speed of passive side, in other words, engine 100 change to 5 grades in advance by belt train 101 and motor-driven gear 400,
It can then ensure to depress by the rotating speed of engine 100 in the engaging process of second clutch 502, so as to which gearbox 200 is changed
Gear and main clutch smooth engagement.Gearbox 5 is kept off gearratio and substitutes into (1), i can be calculatedM=9.78, therefore can also
Meet the requirement that electricity is wriggled and DIRECT ENERGY reclaims.The gearshift of higher speed needs higher power demand, in belt pulley
Be 101 etc. can support in the case of, the degree of engagement of second clutch 502 can also be controlled, so as to carry out power compensation.
Analyzed more than, the control method of following mixed power plant can also be proposed：When vehicle electrical is wriggled, first
Clutch 501 separates, and second clutch 502 engages, and dynamoelectric machine 300 drives vehicle to wriggle；When vehicle regenerative is braked, the
One clutch 501 separates, and second clutch 502 engages, and dynamoelectric machine 300 directly carries out energy regenerating；During vehicle shift,
When dynamoelectric machine 300 can provide enough compensation power, first clutch 501 separates, and second clutch 502 engages,
Dynamoelectric machine 300 carries out shifting power compensation, when the compensation underpower that dynamoelectric machine 300 provides, then controls the
The degree of engagement of two clutches 502, dynamoelectric machine 300 and engine 100 provide compensation power together.
It is noted that before above operating mode is entered, it may be possible to which engine 100 is shut down, or driving electric/generator 300
Being generated electricity, then first clutch 501 first separates, and then dynamoelectric machine 300 carries out speed governing, and second clutch 502 engages,
The power can driving vehicle of dynamoelectric machine 300 is wriggled, either Direct Regeneration braking or shifting power compensation.
Further, since dynamoelectric machine 300 is arranged in the back side of engine 100, space is more nervous, and needs to control
Degree of engagement processed, therefore first clutch 501 and second clutch 502 are realized preferably by multi-disc wet clutch.
The mixed power plant of the specific embodiment of the invention, including：Engine, it includes belt train；Gearbox,
It includes main reducing gear gear wheel；Dynamoelectric machine；Motor-driven gear, with the main reducing gear gear wheel engaged transmission, tool
There is at least five forward gear；First clutch, for connecting the dynamoelectric machine and the belt train；Second clutch
Device, for connecting the dynamoelectric machine and the motor-driven gear, because dynamoelectric machine passes through the first clutch respectively
Device, second clutch and engine, main reducing gear are connected into action edge transmission, therefore can realize that shifting power compensates, or
Vehicle electrical is wriggled, and realizes that Direct Regeneration is braked.
It is electric described in described mixed power plant using mixed power plant of the invention and the method accordingly controlled
Dynamic/generator is connected into action edge transmission by the first clutch, second clutch and engine, main reducing gear respectively,
Therefore it can realize that shifting power compensates, either realize vehicle electrical wriggling or realize that Direct Regeneration is braked, pass through the realization
The method of mixed power plant control, it can control described device adjusting working mode in the state of difference.
