Description
Technical field
The invention belongs to the technical fields of automobile power speed change system.More particularly it relates to a kind of AMT speed changer
Automobile gear selecting drive control method.
Background technique
Hyundai Motor is easy to appear after automobile gear shift and changes because the automobile gear selecting drive control algorithm of AMT speed changer is unreasonable
Situations such as gear failure, pause and transition in rhythm or melody sense is stronger.
Gear selecting control acts on extremely important in AMT speed changer, and gear selecting and shift cooperate and could rationally be put into gear, if
With reasonable, it may appear that the thing of strong pause and transition in rhythm or melody sense or the position that cannot hang up on file seriously affects driving experience and driving safety
Property.
Existing AMT speed changer gear selecting technique algorithm cannot accurately carry out selection gear, it may occur that gear selecting failure, feelings out of supply
Condition influences driving experience.
Summary of the invention
The present invention provides a kind of automobile gear selecting drive control method of AMT speed changer, and the purpose is to make block selecting control more
Add precisely.
For reasonably optimizing AMT speed changer gear selecting control strategy, four-stage is subdivided into gear selecting: be respectively boost phase,
Constant velocity stage, deboost phase and stage in place, make to control so more accurate.
To achieve the goals above, the technical scheme adopted by the invention is as follows:
The automobile gear selecting drive control method of AMT speed changer of the invention is divided into four when plucking neutral gear and carrying out selection gear
A control stage: being boost phase, constant velocity stage, deboost phase and stage in place respectively；The driving force of boost phase, block selecting are real
When border position is greater than target position, the direction that driving direction is 0, on the contrary it is 1 direction.
The driving force of the boost phase output, enters constant velocity stage when block selecting physical location is greater than target position,
If being more than 0.2ms in this stage residence time, driving force increases by 10%, the residence time is then calculated again, if surpassed again
Cross 0.2ms, driving force is further added by 10%, until pass through or time-out.
The driving force of constant velocity stage's output, when block selecting physical location subtracts target position absolute value of the difference less than one
When determining range, into the deboost phase；If being more than 0.2ms in this stage residence time, driving force increases by 10%, then again
The residence time is calculated, if driving force is further added by 10% again more than 0.2ms, until passing through or overtime.
The driving force of the deboost phase output, this driving force is reversed brake force, when block selecting physical location subtracts
When target position absolute value of the difference is less than a certain range or braking time is more than 0.2ms, then enters the stage in place.
The stage in place, first drive value clear 0, and start timing, still meet locality condition then more than 0.2ms
Block selecting flag set in place；It is such as unsatisfactory for, then restarts output driving power, judge again until meeting locality condition again.
The present invention by adopting the above technical scheme, solves the accuracy of the automobile gear selecting drive control algorithm of AMT speed changer,
More optimal Rule of judgment is provided when speed changer is shifted gears, makes to put into gear more smooth, meets the comfort of driving experience
Requirement.
Specific embodiment
Below by the description to embodiment, specific embodiments of the present invention will be described in further detail, with side
Those skilled in the art is helped to have more complete, accurate and deep understanding to inventive concept of the invention, technical solution.
The present invention is a kind of automobile gear selecting drive control method of AMT speed changer.
In order to solve the problems, such as of the existing technology and overcome its defect, realize so that block selecting controls more accurate invention
Purpose, the technical scheme adopted by the invention is as follows:
When plucking neutral gear and carrying out selection gear, it is divided into four control stages: is boost phase, constant velocity stage, braking respectively
Stage and in place stage；
The driving force of boost phase, when block selecting physical location is greater than target position, the direction that driving direction is 0, on the contrary it is 1
Direction.
The Rule of judgment of four-stage is respectively:
The driving force of the block selecting boost phase output, at the uniform velocity rank is entered when block selecting physical location is greater than target position
Section, if being more than 0.2ms in this stage residence time, driving force increases by 10%, the residence time is then calculated again, if again
More than 0.2ms, driving force is further added by 10%, until pass through or time-out.
The driving force of the described block selecting constant velocity stage output, when to subtract target position absolute value of the difference small for block selecting physical location
When a certain range, into the deboost phase；If being more than 0.2ms in this stage residence time, driving force increases by 10%, then
Calculate the residence time again, if driving force is further added by 10% again more than 0.2ms, until pass through or time-out.
The driving force of the block selecting deboost phase output, this driving force is reversed brake force, when block selecting physical location
When subtracting target position absolute value of the difference less than a certain range or braking time is more than 0.2ms, then enters the stage in place.
The stage in place, first drive value clear 0, and start timing, still meet locality condition then more than 0.2ms
Block selecting flag set in place；It is such as unsatisfactory for, then restarts output driving power, judge again until meeting locality condition again.
The stage in place, that is, block selecting decelerating phase.
The present invention is exemplarily described above, it is clear that present invention specific implementation is not subject to the restrictions described above,
As long as using the improvement for the various unsubstantialities that the inventive concept and technical scheme of the present invention carry out, or not improved this is sent out
Bright conception and technical scheme directly apply to other occasions, within the scope of the present invention.
