After speed=0), at the time of have passed through stipulated time (such as 1 second), step S20 makes to be judged certainly.It is being determined as vehicle 10
In the case of on the move, terminate present treatment.On the other hand, in the case where being determined as that vehicle 10 is not in movement, it is transferred to
Step S21, prohibitory sign will be restarted and be set to "Off".
Next, figure 4 illustrates the execution example of above-mentioned processing.Before moment t1, vehicle 10 travels on road, weight
It is "Off" to open prohibitory sign, and seat occupancy sensor 39 is "ON", with inputting the section to be opened by the operation of air throttle handle 14
Correspondingly, engine 30 is operated the aperture of valve.
In moment t1, after driver releases the operation of air throttle handle 14, the speed of vehicle 10 is passed through along with the time
And reduce.In moment t2, the speed vanishing of vehicle 10, it is determined as that vehicle 10 travels stop condition (to stop as defined in meeting
Only state), begin to pass through time TX measurement.In moment t3, detect that elapsed time TX has reached defined stand-by time T0
When, engine 30 is automatically stopped.
In moment t4, for driver after vehicle 10 gets off, seat occupancy sensor 39 turns into "Off".Afterwards, driver gripping side
To push 12 after the action that vehicle 10 moves starts, the translational speed of vehicle 10 is detected by vehicle speed sensor 35.Then, exist
Moment t5, when to detect translational speed be more than setting v1, restart prohibitory sign and be set as "ON".
After moment t5, driver, which continues to push vehicle 10, to move, thus, in moment t6, even if air throttle handle 14
Open, be "ON" due to restarting prohibitory sign, also maintain the halted state of engine 30.
Then, vehicle 10 after moment t7 speed turns into zero, is restarted by the hand push of driver and the mobile stopping that carrying out
Prohibitory sign is set as "Off".
Then, in moment t8, when driver is sat on vehicle 10 to drive vehicle 10, seat occupancy sensor 39 turns into
"ON".Then, in moment t9, when air throttle handle 14 is rotated (operation), according to its rotation amount (aperture of air throttle), start
Machine 30 is to automatically restart.
According to present embodiment, following excellent effect is obtained.
(1) when engine 30 is automatic stop condition, grip direction in driver and push what vehicle 10 moved 12
In the case of, forbid restarting automatically, even if there is the operation of air throttle handle 14, engine 30 is maintained automatic stop condition not
Become.Thereby, it is possible to avoid causing the undesirable vehicle start of driver.
(2) vehicle 10 by the hand push of driver and the mobile stopping that carrying out after, the possibility that vehicle traveling starts be present
Property.Then, in the case where being determined as the mobile stopping of vehicle 10, by engine 30 restart automatically forbid releasing, so as to
Vehicle start after being allowed to successfully is carried out.
(3) when engine 30 is automatically stopped, in the case where driver takes a seat, driver wants to make vehicle travels can
Energy property is higher, and in the case where not taking a seat, the possibility that driver wants to travel vehicle is relatively low.Therefore, it is being judged to driving
In the case that member takes a seat, it is not prohibited by the automatic of engine 30 and restarts, thereby, it is possible to prevent from exceedingly forbidding the automatic of engine 30
Restart and then fail to respond to the undesirable condition of the starting meaning of driver.
(4) in the case where driver takes a seat, there is a possibility that vehicle traveling starts.Then, do not taken a seat from driver
And the forbidden state of restarting automatically of engine 30 rises, in the case where being determined as that driver takes a seat, by engine 30 from
It is dynamic restart forbid releasing, successfully start so as to the vehicle start after being allowed to.
(5) vehicle etc. is push due to driver at full tilt and in the case that the translational speed of vehicle 10 accelerates, air throttle
The possibility that handle 14 is operated is higher.On the other hand, vehicle start is carried out after push vehicle movement there is also driver
The possibility of action.Then, vehicle 10 translational speed for more than setting and in the case of the possibility height of vehicle start,
Prohibitory sign will be restarted and be set to "ON", forbid the automatic of engine 30 to restart.On the other hand, it is less than in the translational speed of vehicle 10
Setting and possibility that air throttle handle 14 is operated it is relatively low in the case of, will restart prohibitory sign is set to "Off", makes to start
Machine 30 can restart automatically.In such manner, it is possible to avoid undesirable vehicle start, and the vehicle start to be carried out after being allowed to
More successfully start.
Illustrate modified embodiment of the present embodiment below.
In Fig. 3 step 20, the releasing restarted and forbidden can also be considered as when it is "ON" to be determined as seat occupancy sensor 39
Condition is set up.In this case, when it is "ON" to be determined as seat occupancy sensor 39, restart prohibitory sign and be released from.In this case,
Also undesirable vehicle start can be avoided, and when driver takes to the vehicle 10 for making the original idea of vehicle traveling high, car
Starting successfully starts.
In Fig. 3 step S11, it can also be judged to meeting traveling in the state of the travel speed of vehicle is more than zero
Stop condition.For example, it is also possible in the case where speed is below speed per hour 1.5km/h, it is judged to meeting traveling stop condition.
Can also will restart prohibitory sign to restart forbidden situation automatically for "ON" and engine 30, by aobvious
Show that the lamp in portion 21 is shown to report.Display part 21 in addition to lamp display notification, can also be by raising equivalent to notifying operator
The sound notification that sound device is carried out.
Taking a seat for driver can also be detected optically by by infrared sensor etc..Or can also be, based on from
The operation input of the component (such as brake etc.) operated in the state of vehicle 10 is seated in driver, judges driver's
Take a seat.In addition it is also possible to be not provided with seat occupancy sensor 39 in vehicle 10, but determined based on the testing result of translational speed etc.
Surely the automatic of engine 30 could be forbidden to restart.In this case, the composition of vehicle 10 can be simplified, while avoid undesirable car
Starting.
The releasing (pass) of starting prohibitory sign in step S21 can also eliminate diagram by be arranged at display part 21
The operation of switch input and manually carry out.For example, being set up even if restarting the condition that prohibitory sign is "ON", grasped there is switch
In the case of inputting, also make to restart prohibitory sign and be returned as "Off".So, the situation for travelling vehicle is wanted in driver
Under, it can more successfully carry out vehicle start.

In step s 12, judge whether vehicle 10 is traveling halted state.Made in vehicle 10 for traveling halted state
Certainly in the case of judging, present treatment is terminated.In the case where being made that negative judges, into step S13.Such as in speed
In the case of being zero, it is determined as that the traveling of vehicle 10 stops.
In following step S13, the elapsed time from being determined as that vehicle 10 is in traveling halted state is measured
TX.In following step S14, judge whether elapsed time TX has reached defined stand-by time T0.It is being made that affirmative
In the case of judgement, into step S15.In the case where being made that negative judges, terminate present treatment.
In step S15, it is considered as automatic stop condition establishment, is automatically stopped engine 30.Specifically, make to oil spout
The fuel injection command of device 31, each output of firing command to igniter 32 stop respectively, stop engine 30.
On the other hand, be determined as in step slo engine 30 be not in operating in the case of, into step S16, judge
Whether the movement of vehicle is had.Here, in the case where the translational speed of vehicle 10 is more than setting v1, it is determined as vehicle
It is mobile.Vehicle 10 move and be made that certainly judge in the case of, into step S19.For example, it is contemplated that the walking to people
Speed, setting v1 is set as speed per hour 3km/h.
In addition, in the case of being made that negative judges in step s 16, in step S17, determine whether there is air throttle and hold
14 operation is inputted (whether air throttle is open state).Have operation input and be made that certainly judge in the case of, enter
Step S18.In the case where being made that negative judges, terminate present treatment.In step S18, be considered as engine 30 restarts bar
Part is set up, and implements automatically to restart (true to start) by starter 34.Thus, vehicle 10 can start to walk.
On the other hand, it is made that in step s 16 in the case of judging certainly, in step S19, judges seat occupancy sensor
Whether 39 be "Off".In the case where seat occupancy sensor 39 is made that judgement certainly for "Off", into step S20.Making
In the case that negative judges, terminate present treatment.In addition, as the concrete example that negative judgement is made in step S19, have as follows
Situation：Engine 30 by idle stop control to be automatically stopped when, driver sit on the seat with pedal landing ground with
Vehicle 10 moves together.
In following step S20, self-braking engine 30 is set to restart automatically (false start).Now, hair is passed through
The false start of motivation 30 and vibration or the sound of caused vehicle 10, there can be the possibility of vehicle start to driver notification
Property.False start mark is set to "ON" in the step s 21.
It is determined as that false start (carries out the feelings of the false start of engine 30 in the case of being masked as "ON" in step s 11
Condition), judge whether the movement of vehicle 10 has stopped in step S22.If now speed=0, it is judged as the shifting of vehicle 10
It is dynamic to stop.In addition, step S22 determinating reference can also be identical with step S16.In addition it is also possible to it is configured to, in vehicle 10
After mobile stopping (after turning into speed=0), at the time of have passed through the stipulated time (such as 1 second) afterwards, step S22 makes to be sentenced certainly
It is fixed.In the case where the movement to vehicle 10 is made that negative judges, into step S23.It is being made that the situation of judgement certainly
Under, after false start mark is set into "Off" in step s 25, engine 30 is back to automatic stop condition in step S15.
In the case of the mobile stopping of vehicle 10, it is not necessary to arouse driver and pay attention to, therefore engine 30 is back to and is automatically stopped
State, suppress the consumption of fuel.
In step S23, judge whether air throttle is defined open state.Made in air throttle open state for as defined in
Certainly in the case of judging, into step S24.In the case where being made that negative judges, terminate present treatment.In step S24
In, the starting inputted by the operation for air throttle handle 14 suppresses control, and the rotation for suppressing engine 30 rises.
Then, figure 6 illustrates the execution example of above-mentioned processing.Before moment t1, vehicle 10 is travelled on road, and vacation is opened
Dynamic to be masked as "Off", seat occupancy sensor 39 is "ON", with inputting the air throttle to be opened by the operation of air throttle handle 14
Aperture correspondingly, engine 30 is operated.
In moment t1, after driver releases the operation of air throttle handle 14, the speed of vehicle 10 is passed through along with the time
And reduce.In moment t2, when the speed of vehicle 10 turns into zero, it is determined as that vehicle 10 travels stop condition (to stop as defined in meeting
Only state), proceed by elapsed time TX measurement.In moment t3, when detecting that elapsed time TX has reached defined standby
Between T0 when, engine 30 is automatically stopped.
In moment t4, for driver after vehicle 10 gets off, seat occupancy sensor 39 turns into "Off".Afterwards, driver gripping side
Push to 12 after the action that vehicle 10 moves starts, the translational speed of vehicle 10 is detected by vehicle speed sensor 35.Then, when
T5 is carved, when to detect translational speed be more than setting v1, by the false start of engine 30.Thus, arouse driver and pay attention to vehicle
For the state that can be started to walk.In addition, in moment t5, false start mark is set as "ON".
In addition, after moment t5, driver, which continues to push vehicle 10, to move, thus, in moment t6 air throttle handle 14
When being opened, perform starting and suppress control, the rising of the rotation of engine 30 is suppressed.
Then, vehicle 10 is by the hand push of driver and the mobile stopping carried out, and in moment t7, speed is less than setting v1
When, engine 30 is back to automatic stop condition.In addition, false start mark is set as "Off".
Then, in moment t8, when driver is in order that vehicle 10 is travelled and is sitting on vehicle 10, seat sensor 39 turns into
"ON".Then, in moment t9, when air throttle handle 14 is rotated (operation), according to its rotation amount (aperture of air throttle), will send out
Motivation 30 really starts.
According to present embodiment, following excellent results can be obtained.
(1) in 30 automatic stop condition of engine, the feelings that direction pushes 12 vehicle 10 and move are gripped in driver
Under condition, the operation with air throttle handle 14 independently makes engine 30 restart automatically (false start).Thereby, it is possible to arouse driver
Pay attention to the possibility for having vehicle start.
(2) in the case of pushing hard vehicle etc. in driver and the translational speed of vehicle 10 is accelerated, air throttle handle 14
The possibility operated is higher.Therefore, vehicle 10 translational speed for it is more than setting and the possibility of vehicle start is high
In the case of, make the false start of engine 30.On the other hand, it is less than setting and the quilt of air throttle handle 14 in the translational speed of vehicle 10
In the case that the possibility of operation is relatively low, it is constant that engine 30 is maintained automatic stop condition.With the mobile status phase of vehicle
Answer ground to determine whether to carry out the false start of engine 30, the consumption of fuel can be suppressed, while arouse the attention of driver.
(3) in the state of engine 30 is by false start, in the case of the mobile stopping of vehicle, engine 30 is returned
To automatic stop condition, it can more suppress the consumption of fuel.
(4) even if having carried out undesirable throttle operation, the situation that driver is sitting on vehicle 10 and driver are from car
10 situations about getting off are compared, it is easier to suppress to start to walk by mistake.Therefore, in the state of vehicle 10 is automatically stopped, it is being determined as
Driver do not take a seat in the case of by the false start of engine 30, engine 30 is maintained in the case where being determined as that driver takes a seat
It is constant for automatic stop condition.In such manner, it is possible to correspondingly determine whether to carry out engine 30 with the presence or absence of taking a seat for driver
False start, thus, it is possible to suppress the consumption of fuel, while arouse the attention of driver.
(5) under the traveling halted state of vehicle 10, when having carried out in the false start of engine 30, by false start mark
"ON" is set to, implements starting in this condition and suppresses control.Thus, even if driver has been carried out not when push vehicle 10 and moving
The operation of desired air throttle handle 14, it can also avoid causing vehicle start.
Hereinafter, modified embodiment of the present embodiment is illustrated.
In Fig. 5 step S12, it can also be judged to meeting that traveling is stopped in the state of the travel speed of vehicle is more than zero
Only condition.For example, it is also possible to it is judged to meeting traveling stop condition in the case where speed is below speed per hour 1.5km/h.
It can also be provided for judging that the air throttle of the gripping state of air throttle handle 14 holds decision mechanism.That is, driving
When the person of sailing pushes the movement of vehicle 10, vehicle start is caused to be because hold air throttle handle 14.Accordingly it is also possible to by air throttle
When holding decision mechanism is determined as that air throttle handle 14 is held, makes the false start of engine 30, arouse the attention of driver.This
Outside, can also be in the situation for being determined as air throttle handle 14 and not being held in the case where setting air throttle to hold decision mechanism
Under, engine 30 is back to automatic stop condition, suppress the consumption of fuel.
In step S16 and step S22, the mobile shape of vehicle 10 can also be judged based on the displacement of vehicle 10
State.In addition, the displacement of vehicle 10 is obtained according to the time integral of translational speed.In addition, the setting of the situation is for example
For 2m.In addition, vehicle 10 can also be judged based on the combination of the setting of translational speed and the both sides of displacement
Mobile status.
Can also after engine 30 is automatically stopped, be determined as driver under seat by seat occupancy sensor 39
In the case of (such as Fig. 6 at the time of t4) or be determined as the operation input from air throttle handle 14 to be more than setting
In the case of (such as Fig. 6 at the time of t5), false start mark is set to "ON".On the other hand, can also be set in false start mark
After "ON", in the case where being determined as that driver sits on the seat by seat occupancy sensor 39 (such as Fig. 6 at the time of t8) or
(such as air throttle turns into after t6 at the time of Fig. 6 in the case that operation input from air throttle handle 14 is less than setting
At the time of closed state), false start mark is set to "Off".Preferably, in the state of the traveling of vehicle stops, at least there is section
In the case of the operation input of valve handle 14, false start mark is set as "ON".For this point, false start mark also may be used
Suppress mark to be referred to as starting to walk.
Can also be that after being automatically stopped of engine 30, in the case where being determined as that vehicle 10 moves, the situation is led to
The lamp for crossing display part 21 is shown to be reported.Display part 21, can also in addition to lamp display notification equivalent to notifying operator
It is configured to carry out sound notification by loudspeaker.Specifically, can also be with the false start phase of engine 30 in step S20
Ying Di, the loudspeaker by being used as notifying operator etc. driving exports the sound or sound etc..Thereby, it is possible to more understandable call out
Play the attention of driver.In addition, as notifying operator, the light sources such as LED can also be used.Such as it can also show on display part 21
Show word etc., to represent engine 30 for the halted state under idle stop control.
In step S24 starting suppresses control, by adjusting the various drives associated with the rotary speed of engine 30
The driving condition of dynamic device, can suppress the rising of the rotary speed of engine 30.Such as can also be that cut-out fuel injector 31 is carried out
Fuel supply and suppress the rising of the rotary speed of engine 30.In addition, carry out electronics control possessing the aperture to air throttle
In the composition of the throttle actuator of system, the air capacity to engine 30 is adjusted to implement to start to walk by the throttle actuator
Suppress.
As step S23 starting suppress control, can also the aperture based on the air throttle detected in step S21, adjust
The degree of integral point ignition delay or ignition cut.Such as in the case where the aperture of air throttle is big, ignition timing is significantly set
Retardation.Or it can also be risen by increasing the ratio of ignition cut to suppress the rotation of engine 30.
In the case of being provided with self-supporting support for eliminating diagram etc. in vehicle 10, it can also be set as stopping in vehicle 10
Stop the false start of engine 30 in the case of car state.
Taking a seat for driver can also be detected optically by by infrared sensor etc..Or it can also be based on next comfortable
The operation for the component (such as brake etc.) that driver is operated in the state of being sitting on vehicle 10 is inputted to be judged.
It can also be configured to, in the case where false start mark turns into "open" state, throttle valve operation is invalid.Specifically,
Can also be that the operation input of air throttles of the ECU20 for being carried out under being masked as "open" state in false start imposes electronic lock.
