Any one structure that has the generator drive of can be used as and can be used as electric motor driven known synchronous generator-motor of motor M G1 and motor M G2 by inverter 41,42, is carried out exchange of electric power with storage battery 50. Inverter 41,42 and storage battery 50 bonded assembly electric wireline 54 are made of each inverter 41,42 shared positive electrode bus and negative pole bus, and the electric power of one of motor M G1, MG2 generating can be by another electrical consumption.Therefore, storage battery 50 discharges and recharges according to the electric power or the power shortage of motor M G1, any one generation of MG2.In addition, when obtaining the balance of electric power revenue and expenditure by motor M G1, MG2, then storage battery 50 does not does not just discharge and recharge.Motor M G1, MG2 each by motor with electronic control unit (below be called motor ECU) 40 drive controlling.Import the necessary signals that drive controlling motor M G1, MG2 use to motor ECU40, for example the signal of the position of rotation detecting sensor of using from the position of rotation of the rotor that detects motor M G1, MG2 43,44 or input go out by not shown current sensor senses, be applied to phase current on motor M G1, the MG2 etc., by motor ECU40 to inverter 41,42 output switch control signals.The signal that motor ECU40 comes according to various sensors, monitoring motor MG1,, MG2 operative condition, detect the state of operated motor MG1, MG2 well, for example because of inverter 41,42 unusually can not operated motor MG1, MG2 state, or motor M G1, MG2 take place unusual and state that can not turn round.Motor ECU40 and hybrid power are with electronic control unit 70 connection of communicating by letter, according to the control signal of using electronic control unit 70 from hybrid power, in the time of drive controlling motor M G1, MG2, as required, the data relevant with the operative condition of motor M G1, MG2 are exported with electronic control unit 70 to hybrid power.
Hybrid power is made of the microprocessor that with CPU72 is the center with electronic control unit 70, except CPU72, also has ROM74, the RAM76 of temporary memory data and the not shown input and output port and the communication port of memory handler.The residual fuel amount of coming from the fuel meter 23a that is installed on the Fuel Tank 23 or from the ignition signal of ignition lock 80, shift position SP from the shift position sensor 82 of the operating position that detects shifter bar 81, acceleration pedal aperture Acc from the accelerator pedal position sensor 84 of the depression amount that detects acceleration pedal 83, from the brake pedal position BP of the brake pedal position sensor 86 of the depression amount that detects brake pedal 85, from the vehicle velocity V of car speed sensor 88 etc. by input port to hybrid power with electronic control unit 70 inputs.As aforementioned, by communication port and Engine ECU 24 or motor ECU40, storage battery ECU52 connects hybrid power with electronic control unit 70, and with Engine ECU 24 or motor ECU40, storage battery ECU52 exchanges various control signals or data.
So the hybrid vehicle 20 of the embodiment of structure based on chaufeur to the depression amount of acceleration pedal 83 corresponding acceleration pedal aperture Acc and vehicle velocity V, calculating should be to the moment of torsion that requires as the gear ring axle 32a of axle drive shaft output, running control driving engine 22 and motor M G1 and motor M G2 will be requiring the corresponding demanded driving force of wanting of moment of torsion to export to gear ring axle 32a with this.Running control as driving engine 22 and motor M G1 and motor M G2, have: at running control driving engine 22, with from driving engine 22 output the time with the power of wanting demanded driving force to match, drive controlling motor M G1 and motor M G2, so that carry out torque conversion by power distribution integration mechanism 30 with motor M G1 and motor M G2 from the whole of power of driving engine 22 outputs, with torque conversion operation mode to gear ring axle 32a output; Or at running control driving engine 22, with from driving engine 22 output the time with the power of wanting the needed electric power sum of discharging and recharging of demanded driving force and storage battery 50 to match, drive controlling motor M G1 and motor M G2, with along with discharging and recharging of storage battery 50 will be a part of along with power distribution integration mechanism 30 and torque conversion due to motor M G1 and the motor M G2 from the whole of the power of driving engine 22 output or its, the charge-discharge drive mode of will demanded driving force exporting to gear ring axle 32a; And the running of shutting engine down 22, with will with want power that demanded driving force matches to the turn round motor rotation pattern etc. of control of the mode of gear ring axle 32a output from motor M G2.
Below, unusual to action, the particularly failure of fuel of the hybrid vehicle 20 of the embodiment of formation like this and driving engine 22, the action that the unusual grade of motor M G1 causes can not generating state the time describes.The diagram of circuit of the example that Fig. 2 handles during for the starting carried out with electronic control unit 70 when connecting ignition lock 80, by hybrid power, Fig. 3 be to connect ignition lock 80 and starting back, used the diagram of circuit of an example of the counting processing that electronic control unit 70 carries out repeatedly by hybrid power.
When handling when carrying out starting, the hybrid power CPU72 of electronic control unit 70, at first, for initialization with counting machine with sign Fc and be set at 0 value (step S100), but and the drive-system of check engine 22 and motor M G1, MG2, inverter 41,42 etc. whether be running state (step S110).Relevant counting machine is narrated in the back with sign Fc.Be not only self whether having taken place unusually of equipment such as check engine 22 and motor M G1, MG2, inverter 41,42 but whether drive-system is the inspection of running state, also will check whether be the state that can carry out to the fuel feeding of driving engine 22.In addition, these inspections can be undertaken by the monitoring data that input Engine ECU 24 and motor ECU40 produce.Under without any unusual normal circumstances, in step S120, draw the judgement of certainty, permission is handled when finishing starting according to travel usually (step S130) that the operation of driver's accelerator pedal 83 switches to motor rotation pattern or torque conversion operation mode, charge-discharge drive mode and travels.
Now, for any unusual situation takes place, particularly because failure of fuel makes state that driving engine 22 can not turn round or because state, the driving engine 22 that driving engine 22 can not be turned round of driving engine 22 can turn round because motor M G1 unusual and the state that can not generate electricity, because inverter 41 unusual and state that can not drive motor MG1 etc. can not generate electricity and consider to the electrically-charged situation that can not generating state of storage battery 50.In this occasion, in step S120, draw negatory judgement, unusual lamp 90 is lighted (step S140), counting machine (カ ウ Application タ) C and threshold value Cref is compared (step S150).At this, counting machine C handles by the illustrated counting machine of Fig. 3 that carries out repeatedly after starting and sets.When threshold value Cref is set in and can not generating state continues, allow the travel number of starts of (モ one タ traveling) of motor, set to be worth 3,4,5,6 etc. mode.When counting machine C deficiency threshold value Cref, under the state of shutting engine down 22 and motor M G1, the motor that allows only to travel with the power from motor M G2 travels (step S160), is in threshold value Cref when above at counting machine C, forbid travelling (step S170), handle when finishing starting.Even take place this can not generating state, when the not enough threshold value Cref of counting machine C, also allow motor to travel to be: though at vehicle can not generating state to be that reason may be at the road junction when stop (crossing), the also cause that can travel vehicle is moved by motor.
Allow to travel usually or motor travels when starting handling, carry out counting machine shown in Figure 3 repeatedly and handle by when starting.Carrying out counting machine when handling, at first, but whether the drive-system of check engine 22 and motor M G1, MG2, inverter 41,42 etc. is running state (step S200).The status checking of the step S100 that handles when this checks with starting is identical.After this, judge that whether this status checking result is can not generating state (step S210), can not generating state the time, counting machine C be set at 0 value (step S220) non-, end counter is handled.Like this, because non-can not generating state the time, counting machine C be set to 0 value, be judged to be can not generating state even handle during by the starting of Fig. 2 when the starting of next time, owing to counting machine C is littler than threshold value Cref, also allows motor to travel.
In step S210, be judged to be can not generating state the time, judging counting machine with when indicating whether Fc is 0 value (step S220), take a decision as to whether motor travel in (step S230), whether the export-restriction Wout that judges storage battery 50 more not enough threshold value Wref (step S240).At this, the export-restriction Wout of storage battery 50 is in an embodiment, to use by temperature sensor 51 detected battery temp Tb and residual capacity (SOC), and pass through the data that communication is read in and used from storage battery ECU52 by the data that storage battery ECU52 sets.Threshold value Wref is the data that are used to prevent that the overdischarge of storage battery 50 from setting, and can try to achieve by the characteristic of storage battery 50.Counting machine when being 1 value or does not travel when middle at motor with sign Fc, and the export-restriction Wout of storage battery 50 is when threshold value Wref is above, directly end counter processing.On the other hand, is 0 value at counting machine with sign Fc, simultaneously also in motor travels, and during the export-restriction Wout of storage battery 50 deficiency threshold value Wref, at counting machine C only in increase value 1 (the step S250), with indicating the Fc value of being set at 1 (step S260), end counter is handled with counting machine.Like this, counting machine is with sign Fc value of being set to 1 when counting machine C increases,, draws in step S220 and negatoryly declares timer-operated result and do not carry out the increase processing of counting machine C with after indicating Fc value of being set to 1 at counting machine.Thereby when hybrid vehicle 20 startings and counting machine C increase, thereafter, hybrid vehicle 20 stops, and does not increase counting machine C up to starting.
Handle during with the starting of Fig. 2 and during the counting machine treatment combination ground consideration of Fig. 3, even because unusual, the motor M G1 of failure of fuel or driving engine 22 unusual etc. makes when can not generating state continuing, till the number of times of setting by threshold value Cref, the starting that allows motor to travel, but when reaching the number of times of setting by threshold value Cref, forbid the starting of travelling.Because the supply of fuel or the maintenance of driving engine 22 and motor M G1 etc. have been eliminated can not generating state the time, allowing the starting of travelling usually during starts, is clearly 0 value with counting machine C.Its result, even by learn that failure of fuel makes the starting of hybrid vehicle 20 and stops not use repeatedly repeatedly original using method not predeterminedly, also can suppress the overdischarge of storage battery 50, suppress simultaneously to be accompanied by overdischarge and the breakage of the storage battery 50 that produces.
At this, in the hybrid vehicle 20 of embodiment, used the export-restriction Wout of storage battery 50 as the discharge capability of storage battery 50, but be not limited to export-restriction Wout, also can use for example residual capacity of storage battery 50 various data such as (SOC) as discharge capability.
In the hybrid vehicle 20 of embodiment, the power of motor M G2 is by reducing gear 35 speed changes and to gear ring axle 32a output, but also can be as ground as illustrated in the hybrid vehicle 120 of the variation of Fig. 4, the power of motor M G2 is connected with the axletree different with the axletree (with drive wheel 63a, 63b bonded assembly axletree) that connects gear ring axle 32a (among Fig. 4 with wheel 64a, 64b bonded assembly axletree).
In the hybrid vehicle 20 of embodiment, be with the power of driving engine 22 by power distribution integration mechanism 30 to drive wheel 63a, 63b bonded assembly, as the gear ring axle 32a output of axle drive shaft, but also can be illustrated as the hybrid vehicle 220 of the variation of Fig. 5, can include with the bent axle 26 bonded assembly internal rotors 232 of driving engine 22 and with the axle drive shaft bonded assembly outer rotor 234 of power to drive wheel 63a, 63b output, to the axle drive shaft transmission time, with remaining power-supply change-over, be the paired rotor electric machine 230 of electric power with the part of the power of driving engine 22.
In addition, so long as have the electrical generator of the dynamic power that uses driving engine, by from the rechargeable battery (secondary battery) of the power charge of this electrical generator, the hybrid vehicle of electrical motor of electric power output drive strength by electrical generator and rechargeable battery, no matter be which kind of hybrid vehicle does not all have obstruction.Moreover the power take-off implement that is loaded on this hybrid vehicle also can be loaded on the hybrid vehicle vehicle or equipment in addition.
More than, with embodiment concrete example of the present invention is illustrated, but the present invention is not limited to these embodiment, much less, in the scope that does not break away from main idea of the present invention, can adopt various forms to implement.
