Embodiment one
See Fig. 1, the control method of the AMT shift-selecting and changing actuating mechanism that the embodiment of the present invention one provides include with
Lower step:
S11, determine and shift gears unsuccessfully:
It should be noted that during shifting, gearshift refers under the driving of drive mechanism, if normally
If work, precalculated position can be reached within a certain period of time.Described precalculated position is included on block selecting direction
Position and/or the position on direction of putting into gear.
But, if gearshift refers to be stuck in moving process or position sensor breaks down, gearshift refer to through
After crossing the driving of long period, also it is not reaching to precalculated position, now think and shift gears unsuccessfully.
In order to prevent from gearshift from referring in moving process being stuck or due to position sensor breaks down can not
Realize correctly shifting gears, can make to set a maximum duration by each transfer in shift process, if should
Transfer is still not reaching to precalculated position after making to exceed predetermined maximum duration, then it is assumed that shift gears unsuccessfully.
It should be noted that in embodiments of the present invention, described AMT shift-selecting and changing actuating mechanism can be gas
Dynamic shift-selecting and changing actuating mechanism, it is also possible to for electronic shift-selecting and changing actuating mechanism.When for pneumatic shift-selecting and changing actuating mechanism
Time, gearshift refers to can be by solenoid-driven, and drive mechanism described above is electromagnetic valve, described gear selection mechanism
For gear-selecting cylinder, described gearshift is shifting cylinder.When for electronic shift-selecting and changing actuating mechanism, gearshift refers to
Can be passed through by block selecting motor and put into gear motor and actuator drives thereof, this block selecting motor and motor of putting into gear
The signal of PWM (pulse width modulation) controls, and the pulse number or the time that are driven by PWM are reached
The effect identical with electromagnetic valve.
During shifting, its transfer is made to include block selecting, pluck gear and put into gear.Therefore, change when AMT choosing
When gear actuator is pneumatic shift-selecting and changing actuating mechanism, in embodiments of the present invention, can be by following several
Method determines shifts gears unsuccessfully:
The first: when pluck gear solenoid-driven range piston time more than the first maximum duration after, gearshift live
Plug does not arrive the centre position of shifting cylinder, it is determined that shift gears unsuccessfully.Wherein, the first maximum duration be
Plucking under the driving of gear electromagnetic valve, range piston moves to the maximum duration needed for the centre position of shifting cylinder again
Plus certain surplus, described surplus can be the twice normally plucking gear required time.
The second: when time of block selecting solenoid-driven block selecting piston more than the second maximum duration after, block selecting is lived
After plug does not arrive the precalculated position of gear-selecting cylinder, it is determined that shift gears unsuccessfully.Wherein, the second maximum duration is
Under the driving of block selecting electromagnetic valve, block selecting piston moves to the maximum duration needed for the precalculated position of gear-selecting cylinder
Plus certain surplus, described surplus can be the twice normally plucking gear required time.
The third: when time of solenoid-driven range piston of putting into gear more than the 3rd maximum duration after, gearshift is lived
Plug is not reaching to the precalculated position of shifting cylinder, it is determined that shift gears unsuccessfully.Wherein, the 3rd maximum duration be
Putting into gear under the driving of electromagnetic valve, the maximum duration needed for range piston moves to the precalculated position of shifting cylinder adds
Upper certain surplus, described surplus can be the twice normally plucking gear required time.
It should be noted that in pneumatic shift-selecting and changing actuating mechanism, the mobile drive gearshift of block selecting piston refers to
Movement on block selecting direction, when block selecting piston moves to position corresponding to target gear, its gearshift driven
Refer to also be moved into the position that target gear is corresponding, therefore, to learn that gearshift refers to by the position of block selecting piston
Position on block selecting direction.Equally, can learn that gearshift refers in direction of putting into gear by the position of range piston
On position.
When AMT shift-selecting and changing actuating mechanism is electronic shift-selecting and changing actuating mechanism, it does not has block selecting piston and changes
Gear piston, is directly driven the movement referring on block selecting direction of shifting gears, by hanging by block selecting motor and actuating device thereof
Gear motor and actuating device thereof directly drive gearshift to refer in the movement putting into gear on direction.
After gearshift refers to be driven the scheduled time, by judging that gearshift refers to that whether reaching precalculated position judges to change
Gear is the most failed.After gearshift refers to reach precalculated position, shift gears successfully, when it is not reaching to precalculated position,
Then shift gears failure.
S12, judge whether block selecting position sensor breaks down:
During shifting, more specifically, gear action, put into gear action and block selecting action generation are being plucked
While, in order to prevent shift process the most back and forth, need to judge whether block selecting position sensor breaks down.
In embodiments of the present invention, can be by judging position signalling and the block selecting drive mechanism of block selecting position sensor
The position that the gearshift driven refers to the most unanimously judges whether block selecting position sensor breaks down.If block selecting position
Put the position that the gearshift that the position signalling of sensor and block selecting drive mechanism drive refers to inconsistent, then block selecting position
Sensor failure, performs step S13, if the position signalling of block selecting position sensor drives machine with block selecting
The position consistency that the gearshift that structure drives refers to, then block selecting position sensor does not breaks down, and performs step S14.
For as a example by pneumatic shift-selecting and changing actuating mechanism, as in figure 2 it is shown, include gear-selecting cylinder 2 and shifting cylinder
3 and gearshift refer to 5, wherein, in gear-selecting cylinder 2, include block selecting piston 1, include in shifting cylinder 3 gearshift live
Plug 4.Wherein, the motion of block selecting piston 1 and range piston 4 drives gearshift to refer to that 5 move accordingly.
Wherein, gearshift refers to 5 for promoting shift fork axle to put into gear, make gear engage, and it is similar to manually change
Putting into gear that block handle is carried out is stirred.
Wherein, the air inlet/vent position on gear-selecting cylinder 2 and number are by shift-selecting and changing actuating mechanism and gear number
Determine.Being characterized in, opening certain or certain a few air inlets by electromagnetic valve, block selecting piston 1 can be driven
Move a certain precalculated position, if when driving time reaches requirement, the gearshift of block selecting position sensor detection
The physical location of the position signalling display block selecting piston 1 referred to the most just on this precalculated position, then judges block selecting
The signal of position sensor is normal, and block selecting position sensor does not break down or gear actuator work
Normally, otherwise, then block selecting position sensor breaks down or gear actuator operation irregularity.But,
In practical work process, position sensor is easy to break down, so, in embodiments of the present invention, if
The signal of position sensor is abnormal, then it is assumed that be that position sensor breaks down.
According to above-mentioned introduction, when described AMT shift-selecting and changing actuating mechanism is pneumatic shift-selecting and changing actuating mechanism,

Keep off and refer to move to precalculated position:
Specifically, block selecting electromagnetic valve controls the air inlet on gear-selecting cylinder and/or air vent, drives block selecting to live
Plug moves predetermined amount of time according to predetermined direction, so that described gearshift refers to move to precalculated position.Described predetermined
Position is that gearshift refers to the position that the direction according to block selecting solenoid-driven reaches in theory.
A2, judge that the position signalling that the gearshift that block selecting position sensor detects refers to is the most consistent with precalculated position:
If the position signalling that the gearshift of block selecting position sensor detection refers to is consistent with precalculated position, namely
Say, the position one that the position signalling that refers to of gearshift of block selecting position sensor detection refers to the gearshift of solenoid-driven
Cause, then block selecting position sensor does not breaks down, otherwise, then block selecting position sensor breaks down.
S13, to use described in the first driving time Schema control gearshift to refer to move to described target gear corresponding
Shift gears and refer to the position on block selecting direction:
After elected gear puts sensor failure, in order to adopt remedial measures, i.e. in order to enable the vehicle to continue

In inventive embodiments, described first driving time pattern drives gearshift to refer to when block selecting drive mechanism
After time exceedes very first time threshold value, AMT controller controls described gearshift according to current vehicle speed and refers to move to
Gearshift corresponding to described target gear refers to the position on block selecting direction.The gearshift that this described target gear is corresponding
Refer to that the gearshift that the position on block selecting direction is corresponding with the gear that current vehicle speed adapts refers to location.
Wherein, target gear is the gear adapted with current vehicle speed.Wherein, very first time threshold value is that block selecting drives
Gearshift is referred to be driven into the maximum duration needed for the first precalculated position by mechanism.Wherein, hold when AMT shifting
When row mechanism is pneumatic shift-selecting and changing actuating mechanism, block selecting drive mechanism is block selecting electromagnetic valve, when AMT choosing is changed
When gear actuator is electronic shift-selecting and changing actuating mechanism, block selecting drive mechanism is motor and drive mechanism thereof.
S14, use described block selecting position sensor position signalling control described gearshift refer to move to described mesh
Mark gearshift corresponding to gear refers to the position on block selecting direction:
If block selecting position sensor does not breaks down, normal position signalling control model is the most still used to control
