D successively executes following D1-D3 condition judgement, if D1-D3 is full after determining fitting input speed acceleration value
Foot then determines that clutch pressure filling is excessive；Otherwise judge that clutch fill is not excessive.
Whether D1 judges the acceleration change amount in first time calibration section less than the first predetermined threshold value；
Specifically, the first predetermined threshold value can be the calibration value of pre-selection, here with Δ aThr1It indicates, when judging first
Between demarcate section T1Acceleration change amount Δ a1Whether less than the first predetermined threshold value Δ aThr1, i.e. Δ a1<ΔaThr1。
Acceleration change amount, the acceleration change in second time calibrating section in section are demarcated in D2 judgement at the first time
Whether amount meets the first preset ratio condition；
Judge Δ a2≥kThr·Δa1；K in formulaThrIt is proportionality coefficient, general value 1-5.
D3 judges the fitting input speed acceleration value in second time calibrating section, second time calibrating section
The difference of input speed acceleration minimum value whether be greater than the second predetermined threshold value.
Specifically, judging Δ aCAL2=ay-amin2>ΔaThr2；Wherein Δ aCAL2Indicate the fitting in the second time calibrating section
Input speed acceleration value, second time calibrating section input speed acceleration minimum value difference；ΔaThr2It indicates
Second predetermined threshold value.

And acceleration change amount Δ a in the period1, T3Input speed acceleration average value a in periodAve3, T2Input in period
Rotating speed acceleration average value amin2And its t at the time of corresponding2With acceleration change amount Δ a in the period2, can refer to Fig. 2.
Wherein, period T1、T2、T3It is whether obviously to be divided according to the fluctuation of output shaft acceleration, reality can be chosen
Logo definite value.
Above-mentioned acceleration information recording gauge be used at last by the input axle acceleration correlation value in different time sections into
Row calculates, and the value of calculating excessively fills judgement for following oil pressure.
The oil pressure excessively fills judgement and includes following multiple sub-steps:
Step 1: judging under current driving condition, within the limits prescribed whether throttle variable (such as accelerator open degree)；
Step 2: the data a based on recordAve1、aAve3, fitting straight line y=kx+b (i.e. by two o'clock determine one directly
Line), and acquire t2Acceleration point a corresponding to the moment straight liney；
Step 3: according to threshold value Δ aThr1(calibration value) judges T1Input speed acceleration change amount Δ a in period1It is
It is no to meet condition: Δ a1<ΔaThr1；
Step 4. judges T2Input speed acceleration change amount Δ a in period2, if meet inequality Δ a2≥kThr·
Δa1；Proportionality coefficient kThrFor calibration value, general value 1-5；
Step 5. judges t2The acceleration change amount Δ a at momentCAL2Whether threshold value Δ a is metThr2(calibration value) requirement:
ΔaCAL2=ay-amin2>ΔaThr2；
If step 1, step 3, step 4, step 5 are all satisfied setting condition, it is determined as clutch pressure under current state
Excessively filling, then execute the relevant operation for reducing oil-filled height.
