Background technology
The road circumstance state that heavy high motor-driven offroad vehicle load change is big, is travelled is again extremely complex, often through natural pond
The badly band such as pool, desert, general hand gear more demanding to dynamic property, passability, safety and intelligence etc.
It is difficult the variation for adapting to this complexity.Although hydraulic automatic speed variator structure is more complicated, and efficiency relies on fluid power than relatively low
The good adaptivity of torque-converters makes it under conditions of cross-country and frequent starting, and control is simple, and simple operation, advantage exists
It is showed on heavy-duty off-road vehicle especially prominent.Matched hydraulic automatic speed variator is primarily adapted for use in general road conditions currently on the market, changes
Shelves pattern is single.High motor-driven offroad vehicle cannot be met and be required to meet various road conditions and environmental working condition requirement, and in order to ensure high machine
The requirement of dynamic offroad vehicle, it is desirable to must assure that and reasonably select Shift gear moment and travelled always in suitable gear, simultaneously
Gear-change operation should ensure that the stationarity and agility of gearshift procedure, improve power performance and fuel economy.
Invention content
The object of the present invention is to provide a kind of hydraulic automatic speed variator shift control methods, solve matched fluid power in the market
The problem of automatic gearbox gear shifting pattern is single.
The technical scheme is that：A kind of hydraulic automatic speed variator shift control method, it is characterised in that：It specifically includes
Following steps：
S1, under different road conditions, pass through sensor collection vehicle situation and pilot control parameter；The difference road conditions are removed
General straight road is stablized outside traveling road conditions, further includes ice and snow road traveling, slope road traveling, highlands traveling, extremely cold area
It exercises, cross-country road driving cycle；
The data acquired are sent to electronic controller disengaging storage by S2, sensor；
S3, it is acquired by the data of above-mentioned operating mode, by the data storage of the data acquired storage to electronic controller

Specific embodiment
To make the purpose of the present invention, content and advantage clearer, with reference to embodiment, the specific implementation to the present invention
Mode is described in further detail.
The present invention provides a kind of hydraulic automatic speed variator shift control method, specifically includes following steps：
S1, under different road conditions, by sensor collection vehicle situation and pilot control parameter, stepped on speed and throttle
Two gearshift control parameters of Board position (accelerator open degree) further include engine oil temperature, water temperature, system pressure as main control parameter
The various controls parameters such as power, brake pedal signal, turn signal, transfer gear box, environmental parameter, pavement state, load capacity；Institute
It states sensor and includes throttle position switch, rotating speed, pressure, temperature sensor, oil temperature, pressure sensor, vehicle speed sensor etc.；
The data acquired are sent to electronic controller disengaging storage by S2, sensor；Different road conditions remove general straight road
Road is stablized outside traveling road conditions, increases ice and snow road traveling, slope road travels, highlands traveling, extremely cold area are exercised, cross-country road
The operating modes such as traveling,
For highlands, the mainly oxygen content of air declines, and motor characteristic curve changes very greatly with plains region,
Engine running parameter is acquired by sensor and is transmitted to electronic controller；
For extremely frigid zones, great changes have taken place for the starting rail pressure of engine, distributive value, and acquiring engine by sensor becomes
Change parameter and be transmitted to electronic controller；
Vehicle is travelled on ice and snow road, the attachment coefficient of vehicle is reduced, by sensor collection vehicle situation simultaneously
It is transmitted in electronic controller；
Vehicle is travelled in cross-country road conditions, vehicle continuous will cross ditch and obstacle detouring, in the case that road conditions are very poor, gearshift
Time and shifting points are required for being adjusted；
S3, it is acquired by the data of above-mentioned operating mode, by the data storage of the data acquired storage to electronic controller
In, preset control program parameter former in electronic controller is supplemented and corrected；
S4, the data after correction are stored in electronic controller, form different shift modes.When the operation shape of vehicle
When condition, running environment and driver's operation change, electronic controller carries out the data acquired in real time and the data of storage
Compare and handle, travel condition of vehicle is identified, optimal Shifting is selected to send out corresponding gearshift to speed changer and is referred to
Enable control gear shifting actuating mechanism gearshift.
The present invention ensure that automobile has best dynamic property using dynamic parameter schedule method；And dynamic is joined
Number schedule can also make automobile select optimal gear on the road surface of different situations, ensure the same of vehicle dynamic quality
When, also ensure the fuel economy of automobile, effectively solve the problems, such as frequently and accident gear shift, can realize meet as possible it is different
Working condition needs, and various aspects integrate optimal shift mode：To different traveling road conditions, corresponding shifting points can be set
Position, makes electronic controller under identical power, meets the gearshift demand under corresponding road conditions；
In special cold district in the case where oil temperature is very low, the parameter of engine can be adjusted, so as to control engine
Rotating speed, and accordingly adjust electronic controller response time；
To reduce impact and dynamic loading during fluid drive, need in shift process to carry out engine active torque,
Rotating speed control, the present invention using electronic controller substitute gearbox TCU, realize self shifter during engine speed from
It is dynamic to adjust, obtain more preferably power performance and fuel economy.
