Unlatching is switched to from shutdown.As a result, set up by gear-shifting operating device 31a the top gear for being used as the shift gear of AMT3.
Then, stop the fuel injection in engine 2, emitted dose becomes " 0 ".Thereafter, by clutch control signal from opening
It opens and is switched to shutdown, automatic clutch 32 is engaged.As a result, in Braking in the state of each driving wheel 7, engine 2
Directly it is coupled by AMT3 with each driving wheel 7.
Therefore, the load of engine 2 is sharply increased, engine speed Ne drastically declines.The engine 2 generated at this time
Cogging be transferred to the rubber tyre part of each driving wheel 7, vibration-damping function absorbs possessed by rubber tyre part.
In addition, since engine speed Ne drastically declines, engine 2 can stop early.As a result, compared with the past, root
And the time meeting resonated consistent with the eigentone of vehicle drive system according to the vibration of the cogging of engine 2
Shorten.
Thereafter, when engine speed Ne is less than egulation rotating speed Nth, in order to measure stipulated time tn, such as start ECU5
Timer internal measurement.Thereafter, when states of the engine speed Ne less than egulation rotating speed Nth passes through stipulated time tn, sentence
Break and reliably stopped for engine 2.
Gear control signal is switched to shutdown from unlatching as a result, is controlled AMT3 for sky by gear-shifting operating device 31a
Gear state.Thereafter, brake control signal is switched to shutdown from unlatching, the brake force that will act on each driving wheel 7 releases.
As described above, the internal combustion engine stop control involved by present embodiment is less than regulation vehicle velocity V th in vehicle velocity V
And when detecting the stopping instruction of engine 2, shift gear is switched to the minimum top gear of gear ratio, and by automatic clutch
Device 32 is switched to transmission state.
Therefore, in the case of the stopping instruction for having engine 2, each driving wheel 7, top gear are in establishment state
AMT3 and engine 2 can directly be coupled.Load can drastically be applied to engine 2 as a result,.As a result, engine can be made
2 stop early.Therefore, the internal combustion engine stop control involved by present embodiment is compared with the past, can mitigate engine
The vibration that engine 2 generates during stopping brings the sense of discomfort of occupant.
In addition, in the internal combustion engine stop control involved by present embodiment, in the stopping for detecting engine 2
During instruction, brake apparatus 41 is by Braking in each driving wheel 7, and vehicle 1 starts during therefore, it is possible to prevent engine stop.
In addition, in the present embodiment, petrol engine has been used as engine 2, but not limited to this, it can also make
By the use of diesel engine as engine 2.In this case, it is not equipped with air throttle 26.In the case of diesel engines, can not
Air throttle is set as full-shut position inhaled air volume to be made drastically to decline in engine stop as in the past, therefore, nothing
Vibration when method mitigates engine stop brings the sense of discomfort of occupant.In the present embodiment, even with such bavin
, also can be with the presence or absence of air throttle independently in the case of oil turbine, vibration when mitigating engine stop brings occupant's
Sense of discomfort.
In the present embodiment, it is considered as in the case where ignition switch 103 has been carried out shutdown operation and has carried out engine
2 stopping instruction, but not limited to this, for example, in the case of being to have the vehicle of idle stop function in vehicle 1 or
It is considered as the stopping instruction for having carried out engine 2 in the case where engine auto stop conditions are set up.
In addition, in the present embodiment, make the shift gear set up in AMT3 for most in above-mentioned engine stop control
High gear, but not limited to this, can also set up the shift gear of the traveling less than top gear.But, it is being set as other than top gear
Shift gear in the case of, be preferably set to close to top gear shift gear (in present embodiment for 4 gear, 3 gear).
Embodiments of the present invention are disclosed above, but it will be appreciated that the scope of the present invention can not departed from
It is changed.Appended claim is intended to comprising all this amendments and equivalent.
