The region of the traveling (EV traveling) of realization is denoted as " can not EV ".In addition, also describing vehicle velocity V in the figure is the case where comparing low speed
With the example of the electric discharge upper limit value of the battery 101 in the case where high speed.As shown in the drawing, there is the limitation (electric discharge of electric discharge output
Upper limit value) it is increased and raised mapping graph according to each SOC with vehicle velocity V.In addition, although illustration omitted, reflects about these
Figure is penetrated, the case where driving mode for vehicle 1 is sport driving mode and the case where common driving mode have prepared different
Mapping graph.
It is specified value with SOC the case where SOC is more than specified value under (the case where " specified value+" and " specified value ++ ")
Situation is compared, and electric discharge upper limit value when high speed becomes larger.Therefore, the battery in the case where SOC is more than specified value, when high speed
101 (primary) discharge capacity increase, thereby, it is possible to ensure the vacant capacity of battery 101.In addition, in SOC more than specified value
In the case of, compared to common driving mode, upper limit value of discharging relatively mitigates sport driving mode.
Illustrate the concrete example of above-mentioned control.It is 50km/h and electric discharge upper limit value under common driving mode, such as in speed
To be not available for EV traveling in the traveling of 15kW, and in the traveling that speed is 80km/h and upper limit value of discharging is 15kW also not
EV traveling can be carried out, in contrast, under sport driving mode, in the traveling that speed is 50km/h and upper limit value of discharging is 15kW
In be not available for EV traveling, on the other hand, speed be 80km/h and discharge upper limit value be 15kW traveling in be able to carry out EV
Traveling.In this way, it is higher by the way that the electric discharge upper limit value of the SOC in the region of high speed to be set to, it is able to carry out the high speed
EV traveling in region.
In addition, setting the drive for only permitting engine ENG according to each speed and SOC in the control of present embodiment
Dynamic region (region for forbidding the electric discharge of battery 101 as caused by the driving of motor MG), but exist make the region (hereinafter,
Referred to as " electric discharge prohibited area ".) different multiple mapping graphs.Fig. 6 shows electric discharge prohibited area corresponding with SOC and speed
Figure.Disclose following curve graph in the figure: this graph illustrate the high speed and low SOC the case where (upper right columns), high
Speed and (left the case where (upper left column), low speed and high SOC the case where (right-bottom column), low speed and low SOC the case where high SOC
Lower column) under engine ENG revolving speed Ne [rpm] and engine ENG output T [Nm] between relationship under electric discharge exclusion area
Domain Y.In addition, the asterisk in curve graph is bsfc (brake specific fuel consumption: net specific fuel consumption)
The vertex of bottom.As shown in the drawing, the more high speed of speed and SOC is higher, then the prohibited area Y that discharges is smaller.Therefore, vehicle
The more high speed of speed and SOC is higher, the frequency of the electric discharge of battery 101 is higher, therefore, SOC can be made to efficiently reduce, from
And ensure in the capacity of battery 101 vacant.
In addition, in the control of present embodiment, when speed is specified value or less and SOC is specified value or more, hair
It cannot be transferred to the warning of sport driving mode out.The warning is shown in display panel (display unit) 55.Fig. 7 is to show the control
The figure of the flow chart of system.As shown in the drawing, here, first, it is determined that the driving mode of vehicle 1 is sport driving mode or general
Logical driving mode (ST2-1).If as a result, sport driving mode, next, it is judged that whether speed is specified value or less
(ST2-2).As a result, being not (no) in specified value situation below, movement cannot be transferred to by judging whether to have had been sent from
The warning (ST2-3) of driving mode releases the warning (ST2-4) if having issued warning (YES).On the other hand, if
Speed is the following (YES) of specified value in step ST2-2, then next, it is judged that SOC whether be upper limit value L (the first upper limit value L1) with
Upper (ST2-5).As a result, SOC is not upper limit value L or more (no), judging whether to have had been sent from cannot be shifted
To the warning (ST2-3) of sport driving mode, if having issued warning (YES), the warning (ST2-4) is released.On the other hand,
If SOC is the above (YES) of upper limit value in step ST2-5, the warning (ST2- that cannot be transferred to sport driving mode is issued
6).Then, vehicle 1 is made to start to walk (ST2-7) in the state of being restricted in the case where keeping sport driving mode.That is, battery
101 SOC as starting performance, even if the original driving force of sport driving mode cannot be played, will not also be shown there is no vacant
Show that the display of panel 55 is changed to " common driving mode ", but making this make vehicle in the state of being shown as " sport driving mode "
1 starting.
In addition, in the control of present embodiment, when set the upper limit value M in sport driving mode as the first upper limit value M 1,
When upper limit value M in common driving mode is the second upper limit value M 2, vehicle stop in the upper limit value M restored of SOC be set as the
The relationship of one upper limit value M, 1 < the second upper limit value M 2.That is, in the case where having selected sport driving mode, and common row has been selected
The case where sailing mode is compared, and the upper limit value M of the SOC in the stopping of vehicle 1 is set as lower value.In this way, stopping in vehicle 1
In only, in the case where having selected sport driving mode, compared with the case where having selected common driving mode, by the upper limit of SOC
Value M is set as lower value, driving force needed for thus can also ensure that the starting of vehicle 1, is able to carry out and has paid attention to movement row
Sail the strong starting of the accelerating ability in mode.
As described above, in the control device of the vehicle driving apparatus of present embodiment, fortune is being selected
In the case where dynamic driving mode of the driving mode as vehicle 1, compared with the case where having selected common driving mode, carry out so that
The battery remaining power that the upper limit value of SOC becomes lower value controls.Carrying out such battery remaining power control is because of In
It, can not be true when battery 101 is fully charged state in the structure for the driving device 100 that the vehicle 1 of present embodiment has
The starting performance for taking care of yourself the so-called motion mode of accelerating ability required by having regarded sport driving mode, so needing than existing
The driving device of hybrid vehicle generates in the SOC of battery vacant earlier.
That is, existing hybrid vehicle driving device (the machine for adjusting torque structure portion TC's without above structure
Driving device) in, in vehicle start without the regenerative electric power based on motor, however the driving by motor consumes electricity
Power, therefore, even if the SOC of battery there is no vacant, can also ensure that starting performance required by sport driving mode.But
In the driving device 100 of the present embodiment with machine for adjusting torque structure portion TC, carried out when vehicle 1 is started to walk based on motor
The regenerative electric power of MG, so being needed in the SOC of battery vacant to play starting performance required by sport driving mode.
In addition, the SOC management of battery carries out area's control in existing control, substantially implements and want to reach regulation area
The control in center, but consider that the control control as described below of special circumstances and further progress is, for example, following control:
When vehicle for a long time on mountain pass (upward trend) when driving, battery slightly discharges, the center in the area SOC cannot be reached, therefore, learn
Control plays a role, it is contemplated that inhibits the electric discharge of battery or drives off mountain pass finally (as being able to carry out the renewable hair based on motor
Electricity situation) and terminate ramp (upwards slope) detect when, reduce SOC quickly.
When specifically, in case where the battery remaining power control to carry out present embodiment, vehicle is on longer
Slope road travel in the case where, by the state of reaching the state of the upward trend completely or slightly going down from that into
The above-mentioned control of row, changes the given threshold (upper limit value) of the recovery of SOC.By the way that the upper limit value of SOC in this case is set
It is set to second upper limit in the case where the first upper limit value L1 and common driving mode in the case where above-mentioned sport driving mode
Value L2, so that the first upper limit value of upper limit value L1 < second L2.As a result, in particular, intentionally reducing the SOC under sport driving mode
Upper limit threshold setting.In addition, the phenomenon that for the state of a control for becoming the center for being not up to SOC because of above-mentioned control,
Implement control as follows: so that the not only upper limit threshold of SOC, but also in the case that the convergency value of SOC also becomes sport driving mode
Convergency value be less than common driving mode in the case where convergency value value.
