Herein, in the case of hope makes the illegal state of engine automatic stop continue, it may occur however that as follows
Loaded down with trivial details thing, i.e. when releasing the illegal state of engine automatic stop every time, user must forbid
The switching manipulation of engine automatic stop.
Therefore, in present embodiment, in view of this, it is determined that forbid period Tx at engine automatic stop
In, if become setting up along with engine auto stop conditions and carrying out the situation of engine automatic stop, root
The illegal state of engine automatic stop is extended according to its result of determination.So, enter suitably according to user view
Row engine automatic stop and electromotor are restarted.
The prolongation of the flow chart of Fig. 2 used below engine automatic stop illegal state to being implemented by ECU21
Process illustrates.Present treatment is implemented with specified period repeatedly by ECU21.
First, in step S11, it is determined that whether prohibition flag is " 1 ".Herein, prohibition flag uses " 1 "
Represent that engine automatic stop is prohibited, represent that engine automatic stop is not prohibited with " 0 ".
When step S11 judging prohibition flag as " 0 ", enter step S12, it is determined whether forbid starting
Machine is automatically stopped.Whether forbid the judgement of engine automatic stop according to whether by driver to operation button 25
Carry out operation to judge.
When step S12 is judged to forbid engine automatic stop, enter step S13, in prohibition flag
If set, in following step S14, set forbid engine automatic stop forbid period Tx.
Forbid that period Tx is down counter, the certain time of regulation is set as initial value.After, forbidding
Start while engine automatic stop to forbid successively decreasing of period Tx.In step S15, make display part 26 point
Bright to have carried out the first notice that engine automatic stop forbids the initial setting of period Tx, knot as notice
Bundle present treatment.On the other hand, when step S12 is judged to be not prohibited by engine automatic stop, directly terminate
Present treatment.
When step S11 judging prohibition flag as " 1 ", enter step S16, it is determined whether have passed through taboo
Only period Tx.Step S16 is judged to, through forbidding period Tx, enter step S27, will forbid
Labelling resets to " 0 ", terminates present treatment.
On the other hand, step S16 is judged to, without when forbidding period Tx, enter step S17, sentence
Determine stop condition establishment to mark whether as " 0 ".Herein, " 1 " expression of stop condition establishment labelling is started
Machine automatic stop condition sets up the state that the rear engine condition of restarting is not set up, and the most virtual electromotor is automatic
Halted state.Additionally, stop condition sets up labelling represents that with " 0 " being not in virtual electromotor stops automatically
Only state.
Step S17 judges, when stop condition establishment is labeled as " 0 ", enter step S18, it is determined that start
Whether machine automatic stop condition is set up.Step S18 is judged to when engine auto stop conditions is set up,
Enter step S19, in stop condition sets up labelling, set set.In following step S20, start
Carry out the counting of duration T y of engine automatic stop virtually, terminate present treatment.It addition, whenever
Automatic stop condition sets up the just accumulative time carrying out engine automatic stop virtually, calculates the persistent period
Ty.On the other hand, step S18 is judged to when engine auto stop conditions is not set up, directly terminates this
Process.
On the other hand, step S17 judges, when stop condition establishment is labeled as " 1 ", enter step S21,
Judge that electromotor restarts whether condition is set up.Step S21 being judged to, electromotor is restarted condition and set up
Time, enter step S22, stop condition is set up labelling and resets to " 0 ", stop the meter of duration T y
Number.On the other hand, step S21 is judged to when the condition of restarting is not set up, directly terminates present treatment.
In step S23, it is determined that whether duration T y is more than stipulated time Th1.Step S23 judges
When duration T y is more than stipulated time Th1, enters step S24, reset and forbid period Tx.This
Place, arranges the value identical with initial value.So, the illegal state of engine automatic stop is extended.Next
Step S25 in, make display part 26 flash and extended the illegal state of engine automatic stop as notice
Second notice.In step S26, duration T y is reset to zero, terminate present treatment.On the other hand,
When step S23 judging duration T y as stipulated time below Th1, directly terminate present treatment.
The prolongation processing mode of engine automatic stop illegal state is carried out by the timetable being then used by Fig. 3
Explanation.
First, by setting set in prohibition flag at moment t11, engine automatic stop is forbidden.
Now, display part 26 starts to light.If setting up at moment t12 engine auto stop conditions, then stop
Condition is set up labelling and is arranged to " 1 ".Now, duration T y starts counting up.If sending out at moment t13
Motivation is restarted condition and is set up, then stop condition establishment labelling is arranged to " 0 ".Now, the persistent period
Ty stops counting.If again setting up at moment t14 engine auto stop conditions, then stop condition becomes day-mark
Note is arranged to " 1 ".Now, duration T y restarts counting.Recur at moment t15 electromotor
Dynamic condition is set up again.Now, it is determined that when moment t11 starts duration time accumulated Ty more than regulation
Between Th1, and reset and forbid period Tx, forbidding that electromotor stops automatically before forbidding period Tx
Only.Additionally, now, display part 26 starts flicker.Can obtain according to the present embodiment described in detail above
To following excellent effect.
Judge to forbid whether period Tx becomes along with electromotor stops automatically forbid engine automatic stop
Only condition is set up and is carried out the situation of engine automatic stop, extends electromotor according to its result of determination and automatically stops
Illegal state only.Now, although be in the situation forbidding engine automatic stop, but but can grasp change
For carrying out the situation of the situation of engine automatic stop virtually.Herein, virtual electromotor is occurred automatically to stop
Even if situation only is it is meant that user wishes to forbid engine automatic stop, it is also at occurring this electromotor certainly
The dynamic traveling state of vehicle stopped, for meeting user view, preferably extend engine automatic stop forbids shape
State.Therefore, accordingly, it is possible to be suitably carried out engine automatic stop according to user view and send out
Motivation is restarted.
Use and following constitute, if i.e. forbidding that in period Tx, electromotor stops automatically at engine automatic stop
The aggregate-value of the duration T y when condition restarted to electromotor when condition only is set up is set up is more than rule
Fix time Th1, then extend the illegal state of engine automatic stop.Now, if forbidding period Tx repeatedly
Virtual automatic engine stop condition occurs, then duration T y is more than stipulated time Th1, and prolongation is started
The self-braking illegal state of machine.Therefore, it is possible to according to the generation shape of virtual automatic engine stop condition
Condition, extends and forbids period Tx.
Use and following constitute, i.e., be derived from user operation engine automatic stop illegal state be derived from
Different notice is carried out under the illegal state of the engine automatic stop automatically prolonged.Therefore, it is possible to make user just
Really recognize the illegal state of the engine automatic stop being derived from user operation and be derived from starting of automatically prolonging
The self-braking illegal state of machine.
(other embodiments)
Such as can change above-mentioned embodiment as follows.
Following composition can also be used, i.e. forbidding that period Tx restarts what condition was set up according to electromotor
Condition is set up number of times Tz and is extended the illegal state of engine automatic stop.It addition, be not limited to electromotor
Restart the establishment number of times of condition, it is also possible to use the establishment number of times of engine auto start conditions.
The prolongation of the flow chart of the use Fig. 4 engine automatic stop illegal state to being implemented by ECU21 processes
Illustrate.Present treatment is implemented with specified period repeatedly by ECU21.To processing identical with Fig. 2 in Fig. 4
Process and give identical number of steps, different at the aspect of additional step S31～S35.
In step S17 of Fig. 4～S21, set up along with engine auto stop conditions and stop condition is become
Day-mark note is set to " 1 ", and then stop condition is set up labelling afterwards resets to " 0 ", in step S31,
Forbid period Tx electromotor is restarted condition set up condition set up number of times Tz be incremented by.Ensuing step
In rapid S32, it is determined that condition sets up whether number of times Tz reaches stipulated number Th2.Step S32 is judged to bar
When part establishment number of times Tz has reached stipulated number Th2, enter step S33, reset and forbid period Tx,
In following step S34, display part 26 is made to flash.It addition, forbid period Tx be set to herein with
The value that initial value is identical.In step S35, condition is set up number of times Tz and resets to zero, terminate present treatment.
According to above-mentioned composition, if forbidding that period Tx conditional sets up number of times Tz at engine automatic stop
Reach stipulated number Th2, then extend the illegal state of engine automatic stop.Now, if forbidding period
Happen over and over again virtual automatic engine stop condition in Tx, then condition establishment number of times Tz reaches stipulated number
Th2, extends the illegal state of engine automatic stop.Therefore, it is possible to automatically stop according to virtual electromotor
Situation occurred only, extends the illegal state of engine automatic stop.
In Fig. 4, although use following composition, i.e. forbidding that period Tx is judged to that bar restarted by electromotor
When the number of times that part has been set up reaches stipulated number Th2, extend the illegal state of engine automatic stop, but
This composition can also be changed.For example, it is also possible to use following composition, i.e. release the taboo of engine automatic stop
Only after state, during by operation button 25 is operable to again forbid engine automatic stop, at this
Secondary condition when forbidding is set up number of times Tz and is set up the time point of number of times Tz more than condition when forbidding last time, prolongs
The self-braking illegal state of long electromotor.
Following composition can also be used, i.e. while calculating duration T y, condition is set up number of times Tz
Carry out in the composition being incremented by, be judged to setting up any one of number of times Tz according to duration T y and condition
It is in the time point of the situation that should extend engine automatic stop illegal state, extends engine automatic stop
Illegal state.
Following composition can also be used, forbidding that period Tx is according to the situation carrying out engine automatic stop
Frequency, be set as variable during the prolongation that period Tx will be forbidden.Such as, as it is shown in figure 5, prohibit
Only the establishment number of times of the automatic stop condition in period Tx is the most, the longest by being set to during prolongation.Now,
Can be with the period of frequent generation engine automatic stop, it is possible to forbid being automatically stopped according to user view.
Or, forbid that the establishment number of times of engine auto stop conditions in period Tx is the most, can be by the extended period
Between be set to the shortest.Now, for being effective to the chance being reduced oil consumption by engine automatic stop improve
Fuel efficiency, it is possible to increase fuel efficiency effect.
In above-mentioned embodiment, make display part 26 light as the first notice, make display part 26 flicker make
It is the second notice, but mode in addition can also be used.For example, it is also possible at display part 26
Show on display that being in the information being automatically stopped in the initial actuating forbidden notifies as first, in display
On the display in portion 26, display is in the information being automatically stopped in the over reach forbidden as the second notice.
Although having used following composition, i.e. judge to be in forbid period Tx by the setting value of time, but
It is to use following composition, i.e. judges to be in forbid period Tx by the setting value of distance.Such as, if
Put predetermined distance as initial value, predetermined distance rear vehicle operating range will be set reach the period of predetermined distance
As forbidding period Tx.
Although having used following composition, i.e. by user, operation button 25 being operated, being considered as carrying out
Predetermined operation and forbid engine automatic stop, but can also change this composition, and use and following constitute,
I.e. forbid engine automatic stop according to the potential idea of driver.Such as, following composition is used, i.e. at car
When speed less than fixing speed and carries out stampede operation to brake pedal, according to releasing trampling of brake pedal
The time of stepping on of changing operating to the stampede operation starting accelerator pedal forbids engine automatic stop.
The engine automatic stop performed by ECU21 is forbidden that process illustrates by the flow chart using Fig. 6.
Present treatment is performed with specified period repeatedly by ECU21.
In step S41 of Fig. 6, it is determined that whether speed is less than fixing speed (e.g., less than 10km/h).
When step S41 judges speed less than fixing speed, enter step S42, carry out from brake pedal to adding
When the changing of speed pedal is stepped on, measure this and change the time of stepping on.On the other hand, step S41 judging, speed is as regulation speed
Time more than spending, directly terminate present treatment.
In step S43, it is determined that change the time of stepping on be whether regulation change the time of stepping on more than.Step S43 judges
Change the time of stepping on be regulation when changing the time of stepping on more than, enter step S44, forbid engine automatic stop.Separately
On the one hand, in step S43 judge change the time of stepping on less than regulation change step on the time time, directly terminate present treatment.
According to above-mentioned composition, from brake pedal to accelerator pedal change the time of stepping on be regulation change the time of stepping on
Time upper, forbade engine automatic stop.Now, it is possible to forbid that electromotor is certainly according to the potential idea of driver
Dynamic stopping.That is, if quickly carrying out changing from brake pedal to accelerator pedal to step on, then it is assumed that driver deposits
Make vehicle quickly set out in hope, i.e. wish to move to potential idea at a distance.If additionally, slowly carried out
Changing from brake pedal to accelerator pedal is stepped on, then it is assumed that driver exists hope makes vehicle slowly set out, i.e.
It is in traffic jam and is not intended to move to potential idea at a distance.If as premise, then can basis
The potential idea of driver, it may be judged whether need to forbid being automatically stopped.
Following composition can also be used, i.e. forbid that electromotor is certainly according to the releasing speed of trampling of brake pedal
Dynamic stopping.Now, calculate brake pedal in step S42～44 of Fig. 6 tramples releasing speed, it is determined that
When this releasing speed is less than fixing speed, forbid engine automatic stop.It addition, be not limited to brake
Pedal trample releasing speed, it would however also be possible to employ constitute as follows, i.e. forbid according to the speed of trampling of accelerator pedal
Engine automatic stop.Now, when trampling speed less than fixing speed of accelerator pedal, forbid that electromotor is certainly
Move and stop.
According to above-mentioned composition, the trampling of brake pedal releases speed less than during fixing speed or accelerator pedal
When trampling speed less than fixing speed, forbid engine automatic stop.Now, it is possible to diving according to driver
Engine automatic stop is forbidden in idea.That is, if it is bigger that trampling under state is trampled in brake releases speed
Or accelerator pedal to trample speed bigger, then it is assumed that driver exists and wishes that vehicle quickly sets out, and i.e. wishes to move
Move potential idea at a distance.If additionally, brake trample under state to trample releasing speed less or add
Speed pedal to trample speed less, then it is assumed that driver exists hope makes vehicle slowly set out, and is i.e. in traffic
Blocking is not intended to move to potential idea at a distance.If as premise, then can be according to driver's
Potential idea, it may be judged whether need to forbid being automatically stopped.
Can also change every time measure changing the time of stepping on from brake pedal to accelerator pedal when stepping on, and according to
The meansigma methods of this time judges the potential idea of driver.
Brake is trampled releasing speed and can be calculated as the time diffusion value relative to brake tread-on quantity,
Accelerate to trample speed to calculate as relative to the time diffusion value accelerating tread-on quantity.
