After control unit 63 makes the initial start-up of engine 2 in output vehicle launch signal and using starter motor 21, in engine 2 Operating in addition to above-mentioned common EV driving conditions are set up, it is stipulated that first EV driving modes perform the feelings that condition is also set up Under condition, engine 2 is stopped, being transferred to first EV driving modes.
Herein, it is stipulated that first EV driving modes jump condition to be set to speed less than the 1st car speed (be, for example, less than conduct The 15km/h of setting).The speed is one, not limited to this.Additionally, as the speed of regulation, being preferably set to engine 2 and opening The speed that can be independently operated after dynamic.
Whether control unit 63 is implemented to that can perform and start in the 2nd car speed being transferred to after first EV driving modes What the restarting of machine 2 was confirmed restarts affirmation mode.Implement this before speed exceedes the speed of regulation and restart confirmation mould Formula.Here, the 2nd car speed is for example set smaller than the speed of 15km/h.The speed is one, not limited to this.
Then, illustration.
Fig. 3 is the flow chart of the control process of vehicle 1, and the control process are for example by being stored at the control of control unit 63 Reason program is performed.
Control unit 63 performs the vehicle launch operation that driver is carried out.(step S1).In step sl, vehicle launch is worked as When signal input is to control unit 63, drives starter motor 21 and make the initial start-up of engine 2.It is (defeated to perform vehicle launch operation Enter vehicle launch signal) for opportunity performs this program.
Then, control unit 63 is based on detection information from accelerator opening test section 56 and charged state test section 57 etc. To judge whether common EV driving conditions set up (step S3), it is being judged as the invalid situation of common EV driving conditions Under, the process returns to step S3.
In step s3, control unit 63 discerns whether to implement first when being judged as that common EV driving conditions are set up EV driving modes (step S4), in the case where being judged as that first EV driving modes can not be implemented, the process returns to step S3。
In step s 4, control unit 63 also meets bus-speed monitoring portion in addition to being set up except common EV driving modes condition In the case of condition of the speed less than 15km/h detected by 55, it is allowed to implement first EV to the transfer of first EV driving modes Driving mode (step S5).
Whether control unit 63 is in order to implement to possess common EV driving functions and to that can perform restarting for internal combustion engine and carry out The first EV driving modes of the function of confirmation, control inverter 45 first, drive dynamotor 4.Stop from not shown simultaneously Injector stop engine 2 to the spray fuel of engine 2.
Control unit 63 preferentially implements the common EV driving modes (function) in first EV driving modes as described above, then That implements internal combustion engine restarts affirmation mode (function) (step S5), and this treatment is terminated.Additionally, exceeding in speed Internal combustion engine is completed before 15km/h restarts affirmation mode (function).
Control unit 63 drives ISG20 to implement opening again for the first time for engine 2 when implementing to restart affirmation mode (function) It is dynamic.
Implement engine 2 it is first restart in the case of, first, will switch 41 by low pressure BMS15 and disconnect, then Switch 40 is closed.Thus, electric power is supplied to ISG20 from the 1st electrical storage device 30, and can be restarted.In engine 2 by again After startup, 41 closures will be switched by low pressure BMS15, thus, be supplied by protection load 38 from ISG20 and the 1st electrical storage device 30 pairs Answer electric power.
Control unit 63 is after first restarting is implemented, even if first EV driving conditions are set up also does not use this Part, forbids to first EV mode shifts.The illegal state continues to the operation due to driver the shut-off of vehicle launch signal (OFF) untill.
That is, control unit 63 after the initial start-up of engine 2 opened (ON) due to vehicle launch signal and carry out, with logical Normal EV driving modes condition is set up and speed is less than 15km/h for condition only implements first EV driving modes 1 time, Speed restarts affirmation mode more than implementation before 15km/h in first EV driving modes.
Also, after first EV driving modes are implemented, only it is transferred to when common EV driving modes condition is set up EV driving modes.
Fig. 4~Fig. 6 is the timing diagram of present embodiment.Due to from the moment t0 of timing diagram to moment t2,3 timing diagrams Change is identical, therefore carries out conclusion explanation for common ground.
First, illustrated on term, " deceleration purpose " refers to release the accelerator pedal 58 that driver is carried out Step on, accelerator opening vanishing, " parking purpose " refers to that vehicle 1 stops and speed vanishing.
Each timing diagram illustrates (moment t0) since the timing of driver's ride-on vehicles.In this condition, vehicle 1 is Halted state, therefore have deceleration purpose or parking purpose.
Driver under this condition starts vehicle 1.Operated by the vehicle launch of driver, perform engine and open for the first time Dynamic operation, engine 2 changes (moment t1) from halted state to operating condition.Afterwards, moved because driver performs vehicle start Make, therefore be changed into without deceleration purpose or parking purpose (moment t2).
Because the later passage of starting-up action (moment t2) is different in Fig. 4~6, therefore individually illustrate.
In fig. 4, by driver along with the starting-up action for stepping on accelerator pedal 58, speed rises and more than rule Definite value (15km/h) (moment t3).
After the state is reached, driver's accelerator-off 58 is stepped on, and accelerator opening turns into below setting value. In this condition, if having met other common EV driving modes enabled conditions (not illustrating), common EV travelings Pattern enabled condition sets up (moment t4).But, due to be also not carried out including engine 2 it is first restart including function just Secondary EV driving modes, therefore usual EV driving modes are not performed.
In the state of usual EV driving modes enabled condition is met, driver makes vehicle deceleration, when speed is less than rule During definite value (15km/h), first EV driving modes enabled condition is set up, and engine 2 stops (moment t5).
First EV driving modes are performed from moment t5 to moment t6.First EV driving modes include usual EV driving functions (constant speed drive that is only carried out by dynamotor, slide (creep) travel, regenerative electric power) and engine restart work( Can, usual EV travelings are first carried out, before speed exceedes setting (15km/h), complete the first of engine 2 and restart.
Then, explanatory diagram 5.
Because Fig. 5 carries out passage until moment t5 with the control of Fig. 4 identicals is dynamic, therefore only explanation moment t5 later control Braking is made.Turn into temporarily stopped state from moment t5 to moment t6 figure 4 illustrates vehicle 1, although and figure 5 illustrates speed Slightly reduce but vehicle 1 does not turn into halted state and performs the first example restarted of engine 2.
Then, explanatory diagram 6.
Because Fig. 6 carries out passage until moment t2 with Fig. 4, Fig. 5 identical control action, thus only explanation moment t2 with Control action afterwards.
In figure 6, the request driving force due to driver after vehicle start action is small, therefore in speed less than regulation During being worth the situation downward driving of (15km/h), engine auto stop conditions are that EV driving modes enabled condition is set up.By In not only speed is less than setting (15km/h) and be to implement EV travelings for the first time after vehicle start-up, therefore perform first EV rows Sail pattern (from moment t3 to moment t4).
First EV driving modes perform the content same with Fig. 4, Fig. 5.
So, the control unit 63 of present embodiment due to only by starter motor 21 by after the initial start-up of engine 2 first It is secondary be transferred to EV driving modes in the case of be attached with to whether the function of being checked of restarting of engine can be performed, therefore Can investigate in advance after vehicle start-up (inspection) internal combustion engine restart system in the presence or absence of defect.
Particularly, the control unit 63 of present embodiment in car speed due to being only less than the 1st car speed (15km/h) In the case of implement possess the first EV driving modes for restarting function of engine, therefore, it is possible in safer velocity band In to that whether can carry out restarting for engine and confirm.Thereby, it is possible in the low-speed region being transferred to before running at high speed In be reliably completed audit function that is unrelated with the purpose of driver and implementing automatically, therefore driver or passenger will not be damaged Comfortableness.
Due to having completed engine before the 2nd car speed (15km/h) as low-speed region is reached in car speed Restart confirmation function, therefore, it is possible to make to restart the reduction of caused supply voltage to being equipped on other systems of vehicle 1 Influence (the system that supply voltage reduction causes that (vehicle stability control device, motor-driven power steering control device etc.) brings Shut down) turn into Min. (influence of the system-down in low vehicle-speed region is smaller).
In first EV driving modes, the function of usual EV driving modes is preferentially performed, secondly perform engine and restart Confirm function.Therefore, it is also to perform engine after the good EV travelings of quietness have been enjoyed to open again even first EV travelings Move and confirm function, therefore driver will not feel under the weather.
In addition, the starter motor 21 and ISG20 of the vehicle 1 of present embodiment are connected to the 1st electric power storage that output voltage is 12V filling Put 30.Thus, compared with the dynamotor 4 driven by high voltage power supply group 34, simple (distribution is thin, distribution strip number is few) can be used Structure make ISG20 and the line of starter motor 21 (being easy to line) and be equipped on vehicle 1.Therefore, it is possible to reduce ISG20 and starter motor The weight of 21 distribution reduces wiring space.
Although disclosing embodiments of the present invention, it is understood that those skilled in the art can not depart from it is of the invention Apply change in the case of scope.It is intended to be contained in all of this modification and equivalent in claims.
