Abstract
The invention provides a method, device and TCU for controlling a shifting rotation speed. The method comprises the steps that the TCU detects a running mode of a vehicle; when the vehicle runs under a pure motor mode, the TCU will send out a shifting instruction to control a clutch to start working if the speed of the vehicle reaches a shifting point; when work of the clutch is found to satisfy preset conditions, the TCU will reduce the clutch transmission torque corresponding to the current shift and increase the clutch transmission torque corresponding to a shift obtained after the shifting; and when the clutch transmission torque corresponding to the current shift is reduced to a first preset threshold value, the TCU will send out a rotation speed request signal to let an HCU adjust the motor rotation speed to be consistent with the rotation speed of a transmission input shaft corresponding to the shift obtained after the shifting. By the scheme, shifting duration can be reduced.

Specific embodiment
At present, the hybrid vehicle of double-clutch automatic transmission is carried, in shift process, with
Under engine mode as a example by upshift control, three phases are can be generally divided into, respectively clutch rushes in advance oil
It is control, torque phase and rotating speed phase stage, corresponding to enable engine speed to drop to gear after upshift
Rotating speed, the rotating speed of electromotor is adjusted by torque control signal indirectly, i.e., by reducing air inflow, pushing away
The three kinds of modes in lag ignition angle and oil-break controlling motor torque, to reaching the reduction of engine speed.
But in this case, due to causing power source speed to be adjusted indirectly by torque control signal
The method of the method for section and non-immediate control power source speed, can extend shift time.And when vehicle row
When this power source of electromotor has been used when sailing, due to electromotor it is relative for the response of torque control signal
It is slower in motor, can further extend shift time.
To cause those skilled in the art to more fully understand the problems referred to above, Fig. 1 is shown in prior art
The procedure chart that hybrid vehicle shifts to 3 gears under pure motor mode by stepping on the gas from 2 gears.It is whole to rise
Clutch control can be divided into (1), (2) and (3) control process during gear, wherein：(1) it is pre- punching oil control
Stage；(2) it is the torque phase control stage；(3) it is the rotating speed phase control stage.

Show that clutch 1 transmits torque；Fig. 1 (e) is speed change curve.
During with 2 gear travelings, driver's vehicle steps on the gas, the throttle signal in (a) in such as Fig. 1
It can be seen that, when the speed that TCU detects the vehicle reaches liter catch point, shifting commands can be sent to control
Clutch work processed, wherein shown in speed visible (e).In the 600ms-900ms time periods in Fig. 1, institute
Oil pump is stated in the pre- punching oily stage, the oil pressure to causing oil pump be enough to the separation for clutch or closure
Enough control pressures are provided.In 900ms, the pre- punching oil stage terminates, in 900ms-1100ms
In time period, it is seen that shown in (d), the TCU reduces by 2 and keeps off the corresponding transmission of clutch 2 torque of gear,
And the corresponding transmission torque of clutch 1 of 3 gear gears is continuously increased until the transmission torque drop of the clutch 2
Low such as can be value 3Nm of clutch Half engagement point to certain value, then the TCU sends torque and asks
Signal is sought so that the rotating speed of HCU controlled motors keeps off turning for the corresponding automatic transmission input shafts of gears with 3
Speed it is identical, wherein torque request signal can be found in it is shown in solid in (d), then the motor shown in (b) solid line turn
It is fast then follow the torque request signal to be accordingly changed, but can be to see due to using torque requests
The rotating speed of Signal Regulation motor is not direct regulative mode, so the rotation speed change of motor corresponds to institute
The change for stating torque request signal is slow, can thus extend shift time.
For the problems referred to above, embodiments provide a kind of control method of gearshift rotating speed, device and
TCU, methods described is included when the corresponding clutch transmission torque of the current shift is reduced to default first
During threshold value, the TCU by send rotating speed request signal so that HCU regulation motors rotating speed to

In being embodied as, for the vehicle for being mounted with double-clutch automatic gearbox, shift process
The middle principal and subordinate's moving plate for needing to separate the corresponding clutch of current shift, and cause the gear pair after gearshift
Principal and subordinate's moving plate of the clutch answered is combined, and controls the combination that clutch work can be principal and subordinate's moving plate
Control pressure is provided.Thus the TCU can send shifting commands to control clutch work.
S23：When it is determined that during the default condition of the clutch on-the-job satisfaction, the TCU reduces working as front
The corresponding clutch transmission torque in position, and increase the corresponding clutch transmission torque of gear after gearshift.
In being embodied as, there can be various methods to judge whether the clutch work meets default
Condition.Whether the time that can such as record the pre- punching of the clutch exceedes the default very first time, when described
When the time that clutch is rushed in advance exceedes the very first time, determine that the clutch has met default
Condition, the very first time can be 300ms.Again such as, it is also possible to detect the oil of the clutch
Press and judge that whether the oil pressure exceedes default Second Threshold, when the oil pressure of the clutch exceedes described the
During two threshold values, the default condition of the clutch on-the-job satisfaction is determined, the Second Threshold can be 1.5Pa.
It should be noted that the Second Threshold of the oil pressure is relevant with speed, speed is bigger, the of the oil pressure
Two threshold values are bigger.
S24：When the corresponding clutch transmission torque of the current shift is reduced to preset first threshold value, institute
State TCU and send rotating speed request signal so that the rotating speed of HCU regulation motors is extremely corresponding with gear after gearshift
Transmission input shaft rotating speed it is consistent.
In being embodied as, when the corresponding clutch transmission torque of the current shift is reduced to default first
During threshold value, that is, when showing that principal and subordinate's moving plate of the clutch of current shift is basically separated, the TCU can send out
Go out rotating speed request signal so that the rotating speed of HCU regulation motors is defeated to variator corresponding with gear after gearshift
The rotating speed for entering axle is consistent.Because the rotating speed of the corresponding transmission input shaft of gear after gearshift may be according to oil
The situation of gate signal changes, and described unanimously i.e. the rotating speed of final regulation motor is extremely corresponding with gear after gearshift
The rotating speed of transmission input shaft is identical.It should be noted that the first threshold can be carried out as needed
Arrange, such as the first threshold can be set to the corresponding clutch transmission of clutch half hitch chalaza and be turned
Square, can be 3Nm.
To cause those skilled in the art to be better understood from the beneficial effect of above-described this method embodiment
Fruit and shift process, Fig. 3 shows that embodiment of the present invention hybrid vehicle passes through under pure motor mode
Step on the gas from 2 gears and shift to the procedure chart of 3 gears.During whole upshift clutch control can be divided into (1),
(2) and (3) control process, wherein：(1) it is the pre- punching oily control stage；(2) it is the torque phase control stage；(3)
For the rotating speed phase control stage.
