The maximum of 3rd open range is less than the minimum value of the first accelerator open degree scope, the 3rd aperture
The minimum value of scope is more than the maximum of the second accelerator open degree scope.Specifically, the first accelerator open degree may range from
80%~100%, the second accelerator open degree may range from 0%~40%, and the 3rd accelerator open degree may range from 40%~80%.
3rd accelerator open degree scope is common accelerator open degree section, if statistical result for accelerator open degree value mainly in common accelerator open degree
Section is not required to then carry out tactful change in large throttle aperture also no longer small accelerator open degree.
Step S24：Count the number N11 of the accelerator open degree value in the range of default first accelerator open degree and the number threshold
Whether the ratio of value N0 is more than default first ratio B1, if so, step S25, if it is not, then performing step S26.
Step S25：Reduce the downshift speed of gear.
The present invention judges the intention of driver and demand by accelerator open degree accounting.When driver be frequently necessary to it is very strong
Power and during vehicle power deficiency, large throttle aperture accounting can be higher.Default first accelerator open degree scope, that is, large throttle aperture model
It encloses.The more low then power of gearbox-gear is stronger.By reducing the downshift speed of each gear, it can realize that vehicle is more operated in
More low-grade location improves dynamic property, meets the stronger power demand of driver, while also engine can be made to be operated in efficient oil
Door aperture section, improves economical.
Step S26：Count the number N12 of the accelerator open degree value in the range of default second accelerator open degree and default institute
Whether the ratio for stating number threshold value N0 is more than default second ratio B2, if so, performing step S27.
Step S27：Gear upshift speed is improved, the maximum of the second accelerator open degree scope is less than first throttle

Due to load-carrying is light, speed of operation is low, need not suddenly accelerate, does not overtake other vehicles, the road gradient is low etc. so that vehicle is frequent
When operating in underload, then small accelerator open degree accounting can be higher, shows as excess drive force.By the upshift speed for promoting a gear
It can realize that vehicle is more operated in more high tap position, engine is made to be operated in efficient accelerator open degree section, gearbox-gear
Higher economy is better, improves the economy of driving.
Referring to Fig. 3, the upshift strategy in shift control strategy for being AMT illustrates.Vehicle control device is according to vehicle number and throttle
Aperture determines whether to shift gears, and has different gearshift curves in different gears.Vehicle control device can collect speed (abscissa) and
Accelerator open degree (ordinate) information, if this coordinate points shifts gears on the right side of current gear gearshift line, changes higher shelves into
Position.It is that vehicle control device has been stored with gearshift control rule as shown in Figure 3, is vehicle vehicle is consigned to client
Production firm analyzes and concludes what is obtained by calculating.The present invention modification gear upshift speed, the curve that will shift gears move to left or
It moves to right.
It the step of raising gear upshift speed, specifically includes：
New upshift strategy is calculated by the second formula and replaces former upshift strategy, second formula is：
Wherein, V4 is new upshift speed, and V3 is former upshift speed, and V0 is minimum gearshift speed, and B3 is the 3rd ratio,
P2 is ratio of the number with the number threshold value of the accelerator open degree value in the 3rd open range.
The corresponding curve of shifting gears of each gear is comprising a minimum gearshift vehicle velocity V 0.When V0 is very low vehicle can be caused firm
Starting is with regard to needing to change more high tap position into so that engine speed is less than minimum operation rotating speed (idling speed), causes to stop working；Gear
Higher power is poorer, if during minimum gearshift 0 very little of vehicle velocity V, the vehicle most of the time can be caused to operate in high tap position, vehicle moves
User demand is just not achieved in power；Part vehicle emission regulation is that requirement vehicle runs one section of typical condition, different gear shift rule
Engine can then be caused to operate in different rotating speed and torque, influence emission test results.Above discharge, stability and minimum dynamic
Power requirement has minimum desired value in entire vehicle design, can be found out by vehicle analogue simulation and verification experimental verification and reach minimum
The minimum gearshift vehicle velocity V 0 of desired value.
It is similar with upshift strategy for the down-shift strategy in the shift control strategy of AMT, it is the prior art, the present embodiment is not
It repeats again.
It the step of reduction gear downshift speed, specifically includes：
New down-shift strategy is calculated by the first formula and replaces former down-shift strategy, first formula is：
Wherein, V2 is the new speed that downshifts, and V1 is former downshift speed, and V9 is highest gearshift speed, and B3 is the 3rd ratio,
P2 is ratio of the number with the number threshold value of the accelerator open degree value in the 3rd open range.
The corresponding curve of shifting gears of each gear is comprising a highest gearshift vehicle V9.When V9 very Gao Shihui cause engine very
High rotating speed can just change more high tap position into, and rotating speed is excessively high to cause vehicle pause and transition in rhythm or melody sense very strong；Gear is lower, and economy is poorer, if most
When height gearshift vehicle V9 is very high, the vehicle most of the time can be caused to operate in low-grade location, vehicle demand is just not achieved in vehicle economy；
Part vehicle emission regulation is that requirement vehicle runs one section of typical condition, and different gear-shifting rules can cause engine to operate in not
Same rotating speed and torque, influences emission test results.Above discharge, stability and lowest economic are required in entire vehicle design all
There is minimum desired value, the highest gearshift vehicle V9 for reaching minimum desired value can be found out by vehicle analogue simulation and verification experimental verification.
It should be noted that the number N1 of the accelerator open degree value of statistics storage is equal to default number threshold value every time
N0, and after carrying out subsequent judgement, be required to empty the accelerator open degree Value Data of storage, and restart to store and count
Number.Such as it is little to count the number N13 of accelerator open degree value in the 3rd open range and the ratio of the number threshold value N0
In default 3rd ratio B3, then the accelerator open degree Value Data of storage is emptied, and restart to store and count；Alternatively,
The number N11 and the ratio of the number threshold value N0 for counting the accelerator open degree value in the range of default first accelerator open degree are not more than
Default first ratio B1, and, count the number N12 of accelerator open degree value in the range of default second accelerator open degree with it is default
The ratio of the number threshold value N0 is not more than default second ratio B2, then empties the accelerator open degree Value Data of storage, and
Restart to store and count.
