It is disconnected whether to need to compensate the idling of vehicle.
S4:Actual idle speed value is worth to according to idling offset and idling setting, and vehicle is controlled according to actual idle speed value
Starting.Wherein, actual idle speed value=idling setting value+idling offset.Vehicle is started by actual idle speed value and ensures vehicle
Start power, avoid the vehicle stall caused by being short of power, lift driving experience.
In one embodiment of the invention, it is further comprising the steps of in step S4：
S5：Detect speed during vehicle idling driving.
In one embodiment of the invention, the speed of vehicle passes through the moment of torsion of engine and the gear ratio calculation of speed changer
Obtain.
S6：Speed when being driven a vehicle according to idling obtains idling correction factor.Wherein, idling correction factor be more than or equal to 0 and
Less than or equal to 1.
In the example of the present invention, the relation such as institute of table 2 between speed and idling correction factor when idling is driven a vehicle
Show.
| Speed (kilometer/hour) | 0 | 4 | 6 | 8 | 10 |
| Correction factor | 1 | 0.8 | 0.5 | 0.3 | 0 |
Table 2
As shown in Table 2, speed is higher when idling travels, and idling correction factor is also small.
S7：Idling offset is modified according to idling correction factor, to be adjusted to actual idle speed value.
After vehicle is successfully started to walk, if idling holding high value, speed is higher whard to control in idling driving conditions,
And there is the phenomenon for altering car.In the example of the present invention, idling correction factor is multiplied by former idling compensation and is worth to final idling
Offset, final idling offset is compensated to the idling of engine, it is ensured that the even running of vehicle.
The control method of vehicle according to embodiments of the present invention, when vehicle start, if being linked into drive shift or reverse gear,
Setting idle speed value can be compensated according to engine water gentle atmospheric pressure, so as to ensure vehicle rising in environment such as plateaus
Performance is walked, avoids stopping working；When idling travels after vehicle start, pass through idling driving speed amendment idling offset, Ke Yibao
The even running of vehicle is demonstrate,proved, and then lifts driving experience.
