Specific implementation mode
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation describes, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Term " first " and " second " in description and claims of this specification and above-mentioned attached drawing etc. are to be used for area
Not different objects, rather than for describing specific sequence.In addition term " comprising " and " having " and their any deformations,
It is intended to cover and non-exclusive includes.Such as it contains the process of series of steps or unit, method, system, product or sets
It is standby not to be set in the step of having listed or unit, but the step of may include not listing or unit.
Provide a kind of AMT drive ranges self-regulating method in embodiments of the present invention may include referring to Fig. 1：
S11, according to shift control parameters, carry out target gear shift；
If S12, failing to target gear shift, the target gear is recorded；
Automatic gear-box control unit (TCU, Transmission ControlUnit) is realized and is controlled AMT, passes through biography
Sensor position signal closed-loop control makes the signal of sensor feedback in goal-setting position range band, to reach control
Purpose.When the position signal of sensor feedback is in range band, but actual fork physical location not up to as defined in position
When, it may appear that phenomena such as shift abnormal sound or shift fail.
TCU normally judges to shift gears by parameters such as position, times, when target gear carries out primary shift failure, record
The target gear.
S13, default adjustment shift curve corresponding with the target gear is obtained, and determines target adjustment curve；
A kind of method of determining target adjustment curve is additionally provided in embodiments of the present invention, including：
Obtain the normal shift curve of vehicle；
The default adjustment shift curve is generated according to the normal shift curve, the default adjustment shift curve includes
Clamping stagnation of shifting gears adjusts curve and overshoot adjusts curve；
Target tune is obtained according to the shift control parameters, AMT wear coefficients and the default adjustment shift curve, determination
Whole curve.
For example, when there is shift failure, the measure taken is usually increase gear shifting force, but due to the abrasion of mechanism
Phenomena such as degree cannot measure or cannot accurately measure, excessive gear shifting force be caused to may result in position overshoot.Work as gear shifting force
When increasing to the limit, it is possible to there is shift failure, agree be that there are catching phenomena for mechanism at this time, it is primary to influence shift
Success rate, shift quality and driving experience etc..As described in Figure 2, shift curve if normal is (1), when vehicle passes through one section
Between run after, shift curve may become (2) or (3), can be changed if carrying out normal shift according to curve (1) at this time
Shelves failure, so needing to carry out shift adjustment according to adjustment curve namely (2) or (3).Curve (2) is to increase to change in fig. 2
There is shift catching phenomenon after keeping off power；Curve (3), which is that TCU preset control parameters are improper, leads to overshoot occur.
It is specific to generate the default method for adjusting curve, may include：
It counts shift control parameters when shift fails and manually adjusts information, and generate the correction data of shift curve；
The normal shift curve is corrected according to the correction data, obtains the default adjustment curve.
Shift control parameters when being failed according to vehicle shift and to manually adjust information for statistical analysis, find corresponding
Then correction data is corrected normalized curve to obtain default adjustment curve.
Correspondingly, the phenomenon that under normal road condition being usually not in shift failure for certain vehicles, but certain
Under special road conditions, such as the section that uphill way, height above sea level are higher or road conditions are more rugged will appear the case where shift fails,
Or in certain the case where also will appear shift failure compared with harsh climate, the embodiment of the present invention at this moment may be used
Another bearing calibration of offer, including：
The correction data of shift curve is generated according to traffic information, air pressure and car load；
The normal shift curve is corrected according to the correction data, is adjusted curve, the adjustment curve
For carrying out gear adjust automatically to the AMT for meeting the automobile for presetting road conditions and environment.
It, can be by combining the information such as engine temperature, TOT Transmission Oil Temperature to be corrected in the correction course.
S14, the shift control parameters are adjusted according to the target adjustment curve, obtains target shift parameter；
S15, it is shifted gears according to the target shift parameter, if shift failure, more according to the adjustment of target adjustment curve
The new target shift parameter, until shifting to the target gear.
According to shifting gears again after target adjustment curve adjust automatically TCU control parameters, by continuous online self-adjusting parameters,
It is finally completed shift.The process is the process that a cycle adjusts repeatedly, still fails if shifting gears after being adjusted by curve, weighs
It is new to determine then adjustment curve determines that control parameter is shifted gears again.
But in the case of multiple shift failure, the process nor a unlimited number cycle, need setting one
A outage threshold, the outage threshold can be the shift frequency of failure, or parameter adjustment number or adjustment time.With this
Outage threshold is, when shift failure, to record the shift frequency of failure for shifting gears the frequency of failure, and judge that the shift frequency of failure is
It is no to have reached predetermined threshold value, that is, outage threshold, if it is, stop adjustment shift control parameters, that is, no longer again
It determines adjustment curve, generates failure message, quote corresponding failure.The failure message can be sent to preset specified device.
The present invention provides a kind of AMT drive ranges self-regulating methods, corresponding default by determination when shift failure
After adjustment shift curve, then shift control parameters are adjusted, are adjusted repeatedly if shift fails again until shifting to
Target gear is realized the adjust automatically of the drive range after failing to shift, is occurred after avoidable AMT vehicle long-plays
The problem of shift failure rear vehicle can not be run, improves the reliability of AMT products.
