Some embodiments of the present application, instead of all the embodiments.Based on the embodiment in the application, those of ordinary skill in the art
All other embodiment obtained without making creative work, shall fall in the protection scope of this application.
Below in conjunction with Fig. 2, Fig. 2 is a kind of side of determining each gear positions of AMT gearbox provided by the embodiment of the present application
The flow chart of method.
Itself specifically includes the following steps:
S101: when vehicle is in parked state, the first gear extreme position nonce and the second gear limit position are utilized
Nonce calculating is set to calculate separately to obtain the first gear extreme position exact value and the second gear extreme position exact value；Wherein,
Each gear of AMT gearbox is followed successively by the first gear, neutral gear, the second gear；
Using common method, maximum power is applied to gear shifting pulling head, obtains the extreme position nonce of two gears, this reality
It applies in example, three pits as shown in Figure 1 from left to right represent the first gear, neutral gear, the second gear respectively.
A kind of mode obtaining gear extreme position is as follows:
Control gear shifting pulling head is moved with maximum power to the direction of the first gear, is obtained the first gear extreme position and is faced
Duration；Control gear shifting pulling head is moved with maximum power to the direction of the second gear, and it is interim to obtain the second gear extreme position
Value.Control gear shifting pulling head is moved to the same direction with maximum power, is limited fill by respective direction in gear shifting pulling head every time
When the limitation set, an extreme position nonce of the gear is recorded, this movement, which is repeated several times, can obtain multiple gears
Extreme position nonce obtains the extreme position exact value of the gear using the method that majority seeks average.
Certainly the extreme position nonce of obtained multiple gears can also be judged, with can reject or determine
Representative extreme position exact value is calculated using this group of extreme position nonce.One of mode is to this
Group extreme position nonce calculates standard deviation, since standard deviation is able to reflect the wave stability of this group of extreme position nonce,
Then average calculating just only can be carried out after calculated standard deviation meets the requirements, the extreme position for obtaining the gear is accurate
Value.
S102: average is sought to the first gear extreme position exact value and the second gear extreme position exact value, is obtained
Neutral gear position nonce；
After the extreme position exact value for successfully obtaining corresponding two gears of both direction in the way of in S101, this step
It is intended to calculated two gears extreme position exact value and carries out average calculating, obtain neutral gear position nonce.By
The position of two gears in gearbox as shown in Figure 1 at left and right sides of neutral gear symmetrically exists relative to neutral gear, certainly, due to
The presence of manufacturing process or particular/special requirement under actual conditions will also result in there are certain deviation or inherently asymmetric, this Shen
It is please in the gearbox of symmetrical relationship with respect to neutral gear just for the first gear and the second gear.
S103: control gear shifting pulling head moves the first preset times to the direction of the first gear from neutral gear position nonce,
The first gear nonce of respective numbers is got, and the first gear exact value is calculated according to the first gear nonce；
On the basis of S102, this step is intended to obtain the exact value of the first gear.It will be seen from figure 1 that the first gear
Extreme position exact value should be located at the left side of the first gear exact value, that is to say, that the first gear exact value can be greater than, certainly, by
In the rigid condition manufactured by gearbox itself, on the basis of obtaining the first gear extreme position exact value, the first gear
Exact value will not be too far at a distance of the first gear extreme position exact value, that is to say, that there are a distance ranges, are located at the distance
The first gear nonce in range should be it is believable, it is on the contrary then insincere.
Can with it is seen from figure 1 that, control is moved in gear shifting pulling head from neutral gear position nonce to the right, that is, wants to control
During gearing device is linked into the first gear, which will receive the resistance of oblique upper left wall on the left of neutral gear pit first
Power can remove the neutral gear pit since the neutral gear pit gradient is relatively slow with lesser power, until entering the first gear pit
And the subsequent resistance by oblique upper wall on the left of the first gear pit, the resistance is larger, is only applying maximum under normal conditions
Power Shi Caihui overcomes the biggish resistance to shift to the first gear extreme position.It therefore, can be by judging wherein by one
A biggish resistance is to determine whether the gearing device has arrived at the first gear exact value nearby and attempts to overcome resistance to the
One gear extreme position is mobile.
It can be by using the method for most averageds, that is, it is interim to collect multiple first gears in such as S101
Value, and average calculating is carried out after through judgement, to obtain the first representative gear exact value.
S104: control gear shifting pulling head moves the first preset times to the direction of the second gear from neutral gear position nonce,
The second gear nonce of respective numbers is got, and the second gear exact value is calculated according to the second gear nonce；
This step is substantially the same with S103, and only after determining the first gear exact value, gear shifting pulling head is placed in sky
Gear is set at nonce, and repeats the described operation of S103 round about, to obtain being located at the second gear on the right side of neutral gear
Exact value.
S105: average is sought to the first gear exact value and the second gear exact value, obtains neutral gear position exact value；
On the basis of S103, S104, this step is accurate according to the first gear exact value and the second gear being calculated
Value carries out average calculating, to obtain neutral gear position exact value.
S106: control gear shifting pulling head moves the second preset times to the direction of the first gear from neutral gear position exact value,
The first synchronous point position nonce of respective numbers is got, and is calculated first together according to the first synchronous point position nonce
Beans-and bullets shooter position exact value；
On the basis of S106, this step is intended to obtain the first synchronous point position exact value.In each AMT gearbox,
It, all can be accordingly same by first during gear shifting pulling head is shifted to the first gear exact value or the second gear exact value from neutral gear
Beans-and bullets shooter and the second synchronous point, correspondence shift to the first gear and the second gear.The synchronous point means and synchronizer phase in gearbox
The position of engagement, be it is essential, due to gearing device pass through synchronous point position when also will receive certain resistance,
How to find each gear synchronous point position accurately is an important foundation for increasing smooth gear shifting.
Since the synchronous point position of each gear is in the mistake that gear shifting pulling head is shifted to the first gear or the second gear from neutral gear
Cheng Zhong, and also will receive certain resistance, therefore can use the mode used in S103 also to carry out by resistance point
Find and confirmation, unlike S103, relative to first gear exact value distance the first gear extreme position exact value away from
From range size, the distance range of first gear synchronous point positional distance the first gear extreme position exact value can be larger, therefore
There are another biggish distance ranges, it can which falls in apart from size using at a distance of the first gear extreme position exact value
The first gear exact value or the first synchronous point position are determined in one distance range.
S107: control gear shifting pulling head moves the second preset times to the direction of the second gear from neutral gear position exact value,
The second synchronous point position nonce of respective numbers is got, and is calculated second together according to the second synchronous point position nonce
Beans-and bullets shooter position exact value；
This step is substantially the same with S106, only after determining the first synchronous point position exact value, by gear shifting pulling head
It is placed at neutral gear position exact value, and repeats the described operation of S106 round about, to obtain being located at the on the right side of neutral gear
Two synchronous point position exact values.
S108: by the first gear extreme position exact value, the second gear extreme position exact value, neutral gear exact value, first
Synchronous point position the second synchronous point of exact value position exact value is recorded and saved in memory.
This step be intended to by the first gear extreme position exact value, the second gear extreme position exact value, neutral gear exact value,
First synchronous point position the second synchronous point of exact value position exact value is recorded and saved in memory, to make accordingly
AMT gearbox realizes accurate shift.
Further, gear can also be carried out to the data saved every preset period of time built-in storage and determines analysis,
It obtains gear and determines log, entire gear positions determination process reappear and abnormal to determine log according to the gear
Analysis.
Based on the above-mentioned technical proposal, the calibration method of a kind of each gear positions of AMT gearbox provided by the embodiments of the present application,
While carrying out extreme position calibration using study to each gear extreme position, the Accurate Points position for also having learnt each gear is obtained
To the Accurate Points position of each gear and the synchronous point position of each gear, improve each mechanical part of transmission internal uses the longevity
