Then, illustration.
Fig. 3 is the flow chart of the control processing of vehicle 1, which handles the control for example by being stored in control unit 63 Processing routine executes.
Control unit 63 executes the vehicle launch operation that driver is carried out.(step S1).In step sl, when vehicle opens When dynamic signal is input to control unit 63, drives starter motor 21 and make 2 initial start-up (step S2) of engine.To perform vehicle Start-up operation (having input vehicle launch signal) is that opportunity executes this program.
Then, control unit 63 is based on the detection information from accelerator opening test section 56 and charged state test section 57 Etc. judging whether common EV driving conditions are true (step S3), it is being judged as the invalid feelings of common EV driving conditions Under condition, 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 mode (step S4), in the case where first EV driving mode cannot be implemented by being judged as, the process returns to step S3。
In step s 4, control unit 63 also meets bus-speed monitoring portion in addition to common EV driving mode condition is set up In the case where condition of the speed detected by 55 less than 15km/h, allow to shift to first EV driving mode first to implement EV driving mode (step S5).
Control unit 63 is in order to implement to have common EV driving functions and restart progress to that whether can execute internal combustion engine The first EV driving mode of the function of confirmation, first control inverter 45, drive motor generator 4.It is simultaneously stopped from not shown Injector to engine 2 spray fuel and make engine 2 stop.
Control unit 63 preferentially implements the common EV driving mode (function) in first EV driving mode as described above, connects Implement internal combustion engine and restart affirmation mode (function) (step S5), by this, processing terminate.In addition, being more than in speed That internal combustion engine is completed before 15km/h restarts affirmation mode (function).
Control unit 63 when implementing to restart affirmation mode (function), drive ISG20 implement engine 2 it is first again Starting.
It in the case where restarting for the first time, firstly, being disconnected switch 41 by low pressure BMS15, is connect in implementation engine 2 By switch 40 be closed.Electric power is supplied to ISG20 from the 1st electrical storage device 30 as a result, and can be carried out and restart.In engine 2 After being restarted, switch 41 is closed by low pressure BMS15, it is negative by protection from ISG20 and 30 couples of the 1st electrical storage device as a result, Carry 38 supply electric power.
Control unit 63 does not use this first EV driving conditions are set up after implementing first restart Part is forbidden to first EV mode shifts.The illegal state continues to the operation due to driver and vehicle launch signal turns off (OFF) until.
That is, control unit 63 due to vehicle launch signal open (ON) and carry out engine 2 initial start-up after, with Common EV driving mode condition is set up and speed is less than 15km/h and only implements first EV driving mode 1 time for condition, Speed is more than to implement before 15km/h to restart affirmation mode in first EV driving mode.
Also, after implementing first EV driving mode, only it is transferred to when common EV driving mode condition is set up EV driving mode.
Fig. 4~Fig. 6 is the timing diagram of present embodiment.T0 to moment t2 at the time of due to from timing diagram, 3 timing diagrams Variation be identical, therefore carry out conclusion explanation for common ground.
Firstly, being illustrated about term, " deceleration intention " refers to the accelerator pedal 58 for releasing that driver is carried out It steps on, accelerator opening becomes zero, and " parking intention " refers to that vehicle 1 stops and speed becomes zero.
Each timing diagram illustrates (moment t0) since the timing of driver's ride-on vehicles.In this state, vehicle 1 It is off state, therefore has deceleration intention or parking intention.
Driver under this condition starts vehicle 1.It is operated by the vehicle launch of driver, it is first to execute engine Start-up operation, engine 2 change (moment t1) from halted state to operating condition.Later, since driver executes vehicle start Movement, therefore become no deceleration intention or parking intention (moment t2).
Since the later passage of starting-up action (moment t2) is different in Fig. 4~6, individually it is illustrated.
In Fig. 4, by driver along with the starting-up action for stepping on accelerator pedal 58, speed rises and is more than Specified value (15km/h) (moment t3).
After reaching the state, driver's accelerator-off 58 is stepped on, accelerator opening become setting value with Under.In this state, if having met other common EV driving mode enabled conditions (not illustrating), common EV Driving mode enabled condition sets up (moment t4).But due to being also not carried out restarting function for the first time and exist including engine 2 Interior first EV driving mode, therefore usual EV driving mode is not executed.
In the state of meeting usual EV driving mode enabled condition, driver makes vehicle deceleration, when speed is less than rule When definite value (15km/h), first EV driving mode enabled condition is set up, and engine 2 stops (moment t5).
First EV driving mode is executed from moment t5 to moment t6.First EV driving mode includes usual EV driving functions (only carried out by motor generator constant speed drive, slide (creep) traveling, regenerative electric power) and engine restart function Can, usual EV traveling is first carried out, before speed is more than specified value (15km/h), completes restarting for the first time for engine 2.
Then, explanatory diagram 5.
Since Fig. 5 carries out passage until moment t5, only illustrates that moment t5 is later so that control identical with Fig. 4 is dynamic Control action.Vehicle 1, which is shown in FIG. 4, becomes temporarily stopped state from moment t5 to moment t6, although and being shown in FIG. 5 Speed slightly has reduction but vehicle 1 does not execute the example of engine 2 restarted for the first time as halted state.
Then, explanatory diagram 6.
Since Fig. 6 carries out passage until moment t2, only illustrates moment t2 with control action identical with Fig. 4, Fig. 5 Later control action.
In Fig. 6, since requested driving force of the driver after vehicle start movement is small, it is less than rule in speed During the situation downward driving of definite value (15km/h), engine auto stop conditions, that is, EV driving mode enabled condition is set up. Since not only speed is less than specified value (15km/h) and is to implement EV traveling for the first time after vehicle start-up, execute first EV driving mode is (from moment t3 to moment t4).
First EV driving mode executes content same as Fig. 4, Fig. 5.
In this way, the control unit 63 of present embodiment is due to only passing through starter motor 21 for after 2 initial start-up of engine first It is secondary be transferred to EV driving mode in the case where be attached with restart the function of being checked to whether engine can be executed, because This can investigate (inspection) restarting in system with the presence or absence of defect in internal combustion engine in advance after vehicle start-up.
In particular, the control unit 63 of present embodiment is due to only in car speed less than the 1st car speed (15km/h) In the case of implement have the first EV driving mode for restarting function of engine, therefore can be in safer speed area To whether can be carried out restarting for engine and confirm in domain.Thereby, it is possible in the low regime being transferred to before running at high speed It is reliably completed unrelated with the intention of driver and automatic implementation audit function in domain, therefore driver will not be damaged or multiplied The comfort of visitor.
Since engine being completed before car speed reaches the 2nd car speed (15km/h) as low-speed region Restart confirmation function, therefore the reduction for restarting caused supply voltage can be made to the other systems for being equipped on vehicle 1 (vehicle stability control device, motor-driven power steering control device etc.) bring of uniting influences (system caused by supply voltage reduces System is shut down) become minimum limit (influence of the system-down in low vehicle-speed region is smaller).
In first EV driving mode, the function of usual EV driving mode is preferentially executed, engine is secondly executed and restarts Confirm function.Therefore, even first EV traveling, and engine is executed again after having enjoyed the good EV traveling of quietness Starting confirmation function, therefore driver will not feel well.
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 Device 30.It, can (wiring be thin, distribution strip number with simple as a result, compared with the motor generator 4 driven by high voltage power supply group 34 Structure less) makes ISG20 and 21 line of starter motor (being easy to line) and is equipped on vehicle 1.Therefore, can reduce ISG20 and The weight of the wiring of starter motor 21 reduces wiring space.
Although disclosing embodiments of the present invention, it is understood that those skilled in the art can not depart from the present invention Range in the case where apply change.All this modifications and equivalent are contained in claims by intention.
