Power battery charging.
It is understandable to enable the above objects, features and advantages of the present invention to become apparent, below in conjunction with the accompanying drawings to the present invention
Specific embodiment be described in detail.
As stated in the Background Art, generally when electrokinetic cell SOC is relatively low or electrokinetic cell discharge capability deficiency, hybrid power
The power source of automobile can enter series model, by driven by engine ISG electric power generations come for power battery charging or provide electric discharge
Power is used to drive vehicle to TM motors.In the present embodiment, the power that ISG electric power generations export is referred to as ISG generated outputs, will
The power to be charged to electrokinetic cell is referred to as the charge power of electrokinetic cell, will carry out energy regenerating by TM motors during braking
When the generated output that provides be referred to as TM generated outputs.In the present embodiment, under the series model distribution of generated output include car
Being in ISG generated outputs under drive pattern distributes for driving vehicle and for power battery charging, is additionally included in Brake Energy
During amount recovery, distribute the ISG generated outputs and TM generated outputs and be used for power battery charging.
In the present embodiment, the calculating for the ISG generated outputs is (by gas pedal by vehicle traction power demand
Depth and speed parsing), power battery charging power demand (according to battery electric quantity is how many and external condition calculates) and vapour
The consumption power demand sum of car annex, and the condition limit such as generating capacity by ISG motors, available charge power of electrokinetic cell
It is made.For example, when the generating capacity of ISG motors is insufficient for vehicle traction power demand, power battery charging power
When demand and consumption power demand three's sum of car accessories, then the ISG generated outputs are true by the generating capacity of ISG motors
It is fixed, it now can not all meet above-mentioned each demand.
In view of being usually to be not present to need to distribute when actually implementing, for the consumption power demand for car accessories
The problem of, therefore, in the present embodiment, the distribution of generated output is sent out based on ISG under the hybrid vehicle series model
Electrical power can not meet for the situation of vehicle traction power demand and power battery charging power demand simultaneously.In addition, this
The inventor of application is additionally contemplates that in Brake energy recovery and can also issue the generated output of TM motors as series model
A part for electrical power, so as to be formerly used for meeting the ISG generated outputs of power battery charging power demand by adjustment come real
It is existing.
In addition, in particular cases even if the SOC of electrokinetic cell is very high, charge power is restricted some, but it is dynamic because mixing
There is larger power demand in some annexes on power automobile, such as under conditions of receiving air-conditioning heat request, can also make to mix
The power source control for closing power vehicle enters series model.
In the present embodiment, when the power source of hybrid vehicle is under series model, step S1 is first carried out, judges to work as
It is preceding which kind of series model be in.Due to a variety of different types of works be present when the power source of hybrid vehicle is in series model
Condition, different series models should take corresponding strategy to go to complete the distribution of generated output under series model.
It is the specific strategy that various series models issue electrical power distribution below with reference to Fig. 1：
If vehicle traction power demand and power battery charging power demand is not present, but the consumption work(of car accessories be present
During rate demand, then step S21 is performed, ISG generated outputs are allocated in the consumption power demand for meeting car accessories.Specifically,
If there is no vehicle traction power demand, such as gearbox gear-shift gear is in park position (P shelves) or neutral gear (N shelves), and without right
The charge requirement of electrokinetic cell, such as SOC are very high, and charging is restricted, but because air-conditioning heat request condition enters series model, this
When ISG generated outputs be only used for the consumption power demand that meets car accessories.
If in the absence of vehicle traction power demand and power battery charging power demand be present, step S22 is performed, will
ISG generated outputs, which are allocated in, meets the power battery charging power demand.Specifically, if needed without vehicle traction power
Ask, such as gearbox shifting gear is in P shelves or N shelves, and have the charge power demand to electrokinetic cell, for example, SOC it is relatively low or
Discharge power can be used relatively low, now ISG generated outputs are used for the charge power for meeting electrokinetic cell.If it should be noted that this
When the consumption power demands of car accessories also be present, then should also be considered simultaneously and ISG generated outputs met into disappearing for car accessories
Consume power demand.
If vehicle traction power demand be present and power battery charging power demand is not present, but disappearing for car accessories be present
When consuming power demand, then step S23 is performed, by the discharge power joint distribution of ISG generated outputs and electrokinetic cell in meeting car
The consumption power demand of driving power demand and car accessories.When specifically, if vehicle traction power demand, such as
Gearbox shifting gear is in drive shift (D shelves) or reverse drive gear (R shelves), and without the charge requirement to electrokinetic cell, such as SOC is very
Height, charge power are restricted, but because air-conditioning heat request condition enters series model, then ISG generated outputs and electrokinetic cell
Discharge power meets the consumption power demand of vehicle traction power demand and car accessories jointly.It is it should be noted that such a
Under series model, it is assumed that the simple consumption that vehicle traction power demand and car accessories are disclosure satisfy that using ISG generated outputs
Power demand, but if the electricity of electrokinetic cell is sufficient, then when actually implementing except utilizing ISG generated outputs, it is also necessary to profit
With the discharge power of electrokinetic cell, it otherwise will make it that automobile dynamic system efficiency is low.
If vehicle traction power demand be present and power battery charging power demand is not present, but the electric discharge energy of electrokinetic cell
When power is insufficient for the power of vehicle traction power demand, then step S24 is performed, distribution ISG generated outputs compensate.Tool
Body, it is higher without the charge requirement to electrokinetic cell, such as SOC if vehicle traction power demand, and the energy of electrokinetic cell
When power is insufficient for the power of vehicle traction power demand, then the ability of electrokinetic cell is compensated not by the power of ISG generatings
Foot meets vehicle traction power demand, so as to being unlikely to cause car power not when electrokinetic cell discharge capability deficiency
Foot.
If the vehicle traction power demand and power battery charging power demand simultaneously be present, step S25 is performed,
Preferentially ISG generated outputs are allocated in and meet vehicle traction power demand, then take into account the charge power of electrokinetic cell.Specifically
Ground, if vehicle traction power demand, electrokinetic cell has a demand of forced charge, such as SOC very low, then ISG generating work(
Rate should meet power battery charging power demand, meet vehicle traction power demand again, if ISG generated outputs are not enough to together
When meeting the consumption power of vehicle traction power demand, power battery charging power demand and car accessories, then it is preferential to meet
Vehicle traction power demand, so as to ensure certain power performance.
If carry out Brake energy recovery, step S26 is performed, the preferential TM generated outputs that distribute fill for electrokinetic cell
Electricity.Specifically, if vehicle deceleration carry out Brake energy recovery, when electrokinetic cell can with charge power be less than TM generated outputs and
When ISG motors can use generated output sum, then reduce the generated output of ISG motors, preferentially distribute the TM generated outputs and be used for
Power battery charging, the generated output of ISG motors is set to be equal to the available charging work(of the electrokinetic cell with TM generated outputs sum
Rate, so as to obtain more preferable economy.In the present embodiment, the electrokinetic cell can be referred to working as electrokinetic cell with charge power
The maximum charge power of preceding permission；The ISG motors can refer to the maximum generation work(that ISG motors can be provided with generated output
Rate.
It should be noted that in the series model of above-mentioned six type, " existing vehicle traction power demand and dynamic electricity
During the forced charge demand of pond " and " in Brake energy recovery " both operating modes under for generated output distribution method be with it is existing
Have that technology is otherwise varied, therefore below in conjunction with specific experiment data to the generated output distribution method under both operating modes
Specific implementation is further described.
When Fig. 2 is the existing vehicle traction power demand of the embodiment of the present invention and dynamic battery forced charge power demand

Rate, that is, meet the power of vehicle traction power demand；301 in Fig. 3 be power coordinate, line 305 is time coordinate, line
302 be the charge power of electrokinetic cell, line 303 is ISG generated outputs, line 304 is TM generated outputs.
As shown in Fig. 2 under series model when ISG electric power generations, if vehicle traction power demand, and ISG
The consumption power that generated output is insufficient for vehicle traction power demand, power battery charging power demand and car accessories needs
When seeking three's sum, ISG generated outputs should meet the charge power demand of electrokinetic cell, meet vehicle traction power need again
Ask, then preferentially meet vehicle traction power demand, so as to ensure certain power performance.From fig. 2 it can be seen that
ISG generated outputs are limited ISG generating capacities by some conditions can not increase (such as Fig. 2 lines 202), in the power (vehicle of TM consumption
The power of driving power demand) increase when (as shown in Fig. 2 lines 204), the charge power of electrokinetic cell is reduced (as schemed
Shown in 2 center lines 203).That is, when the power increase of vehicle traction power demand, reduce and electrokinetic cell is carried out
The power of charging is to meet vehicle traction power demand, so as to ensure certain vehicle traction.
Therefore, in the present embodiment, described be preferentially allocated in the ISG generated outputs meets the vehicle traction power
Demand, then taking into account the power battery charging power demand can specifically include：When ISG generated outputs are insufficient for vehicle
During consumption power demand three's sum of driving power demand, power battery charging power demand and car accessories, meeting
After the consumption power demand for stating car accessories, first meet the vehicle traction power demand, then remaining ISG generated outputs are divided
Assigned in meeting the power battery charging power demand；If the power increase of vehicle traction power demand, reduces electrokinetic cell
Charge power to meet vehicle traction power demand.
As shown in figure 3, if vehicle deceleration carries out Brake energy recovery, now preferentially distribution TM generated outputs are used for power
Battery charges, and so can more carry out energy regenerating so as to obtain more preferable economy.Under this operating mode, carried out by TM motors
Brake energy recovery, now the charge power (as shown in Fig. 3 center lines 302) of electrokinetic cell be equal to ISG generated outputs (in such as Fig. 3
Shown in line 303) and TM generated outputs (as shown in Fig. 3 center lines 304) sum.From figure 3, it can be seen that returned carrying out braking energy
When receipts, by reducing ISG generated outputs come preferentially distributing TM generated outputs is used for power battery charging.
Therefore, in the present embodiment, it is described preferentially to distribute TM generated outputs when carrying out Brake energy recovery and be used for power
Battery charging can specifically include：When carrying out Brake energy recovery, when electrokinetic cell can be less than TM generating work(with charge power
When rate and ISG motors can use generated output sum, reduce the ISG generated outputs, preferentially distribute the TM generated outputs and be used for
Power battery charging, the ISG generated outputs are made to be equal to the available charge power of the electrokinetic cell with TM generated outputs sum.
