The poor control responsiveness of the target position of the clutch can cause that the rotating speed of the input shaft of the gearbox cannot be accurately regulated, so that the gear engaging success rate of the vehicle at the starting gear engaging stage is low.
In order to realize accurate adjustment of the rotating speed of the input shaft of the gearbox and improve the success rate of gear engagement, the embodiment of the application provides a control method of the rotating speed of the input shaft of the gearbox, the target position of a clutch is determined according to the target required position offset of the clutch and the required position of the clutch, the clutch is controlled to be engaged to the target position, the current rotating speed of the input shaft of the gearbox is obtained at set time intervals, if the absolute value of the difference between the current rotating speed and the target rotating speed of the input shaft of the gearbox is larger than a set threshold value, the target position is repeatedly adjusted based on the target required position offset, and gear engagement operation is executed until the absolute value of the difference between the current rotating speed and the target rotating speed is not larger than the set threshold value.
The technical solutions provided by the embodiments of the present application will be described in detail below with reference to the accompanying drawings.
The embodiment of the application provides a method for controlling the rotating speed of an input shaft of a gearbox, as shown in fig. 2, the method comprises the following steps:
step S201, determining the target position of the clutch according to the target required position offset of the clutch and the required position of the clutch.
Wherein the target demand location offset may be a current demand location offset or a stored historical demand location offset.
When the target required position offset is the current required position offset, the current required position offset can be determined according to the maximum rotating speed of the input shaft of the gearbox, the target rotating speed of the input shaft of the gearbox and the position correction coefficient. Wherein the position correction factor is determined based on a target rotational speed of the transmission input shaft. The current required position offset can also be determined according to the maximum position correction coefficient, the target position correction coefficient and the target rotating speed. Wherein the maximum position correction factor and the target position correction factor are determined based on the rotational speed of the input shaft of the gearbox.
In one embodiment, it is also desirable to determine that the vehicle is in a launch gear state of an engine-only mode and that the current gear of the vehicle is neutral before determining the target desired positional offset of the clutch.
And step S202, controlling the clutch to be engaged to a target position, and acquiring the current rotating speed of the input shaft of the gearbox at set time intervals.
After the target position of the clutch is determined, the clutch can be controlled to be engaged to the target position, and the current rotating speed of the input shaft of the gearbox is obtained at set time intervals in the engaging process.
The set time can be freely set, for example, when the set time is 10ms, the rotating speed of the input shaft of the gearbox can be acquired every 10 ms.
Step S203, if the absolute value of the difference between the current rotating speed and the target rotating speed of the input shaft of the gearbox is larger than the set threshold, the target position is repeatedly adjusted based on the target required position offset, and the gear engaging operation is executed until the absolute value of the difference between the current rotating speed and the target rotating speed is not larger than the set threshold.
And if the absolute value of the difference between the current rotating speed of the input shaft of the gearbox and the target rotating speed of the input shaft of the gearbox is not larger than the set threshold value, executing the gear engaging operation.
If the absolute value of the difference between the current rotating speed of the input shaft of the gearbox and the target rotating speed of the input shaft of the gearbox is larger than the set threshold, the maximum rotating speed of the input shaft of the gearbox is obtained, and the target required position offset is determined according to the maximum rotating speed of the input shaft of the gearbox, the target rotating speed of the input shaft of the gearbox and the position correction coefficient. Wherein the position correction factor is determined based on a target rotational speed of the transmission input shaft.
And repeatedly adjusting the target position according to the target required position offset and the required position until the absolute value of the difference between the current rotating speed of the input shaft of the gearbox and the target rotating speed of the input shaft of the gearbox is not greater than a set threshold value, and then executing the gear engaging operation.
In some embodiments, the method for controlling the rotational speed of the input shaft of the transmission proposed by the present application can also be implemented according to the process shown in fig. 3. As shown in fig. 3, the following steps may be included:
step S301, determining that the vehicle is in a starting gear state of a pure engine mode, and the current gear of the vehicle is a neutral gear.
Before the vehicle is subjected to speed regulation and gear engagement, the starting and gear engagement state that the vehicle is in a pure engine mode needs to be determined, and the current gear of the vehicle is a neutral gear. When the vehicle is determined to be in a starting and gear-engaging state in a pure engine mode and the current gear of the vehicle is in a neutral gear, the AMT system can be determined to be needed to execute speed regulation and gear-engaging actions.
In step S302, a target required position offset amount of the clutch is acquired.
The target required position offset of the clutch may be a current required position offset or a stored historical required position offset.
The historical required position offset is determined in the last speed regulating process, and the clutch required position offset is automatically stored after the vehicle controller is powered off. The current required position offset is the clutch required position offset obtained by recalculating after the speed is not properly adjusted by performing speed regulation and gear engagement based on the historical required position offset.
And step S303, determining the target position of the clutch according to the target required position offset of the clutch and the required position of the clutch.
And step S304, controlling the clutch to be engaged to a target position, and acquiring the current rotating speed of the input shaft of the gearbox at set time intervals.
Step S305, determining whether the absolute value of the difference between the current rotating speed and the target rotating speed of the input shaft of the gearbox is larger than a set threshold value; if not, executing step S306; if so, step S307 is executed.
In step S306, a shift operation is performed.
And when the absolute value of the difference between the current rotating speed of the input shaft of the gearbox and the target rotating speed of the input shaft of the gearbox is determined to be not greater than the set threshold value, the AMT system executes a gear engaging action to finish the starting speed-regulating gear engaging process.
And step S307, acquiring the maximum rotating speed of the input shaft of the gearbox, and determining the target required position offset according to the maximum rotating speed of the input shaft of the gearbox, the target rotating speed of the input shaft of the gearbox and the position correction coefficient.
When the absolute value of the difference between the current rotating speed of the input shaft of the gearbox and the target rotating speed of the input shaft of the gearbox is determined to be larger than the set threshold value, the required position offset of the clutch needs to be calculated again. The maximum rotating speed of the input shaft of the gearbox can be obtained, and the target required position offset of the clutch, namely the target required position offset = (the maximum rotating speed of the input shaft of the gearbox-the target rotating speed of the input shaft of the gearbox)/the target rotating speed of the input shaft of the gearbox = K, is determined according to the maximum rotating speed of the input shaft of the gearbox, the target rotating speed of the input shaft of the gearbox and the position correction coefficient. And K is a position correction coefficient, and can be determined according to the target rotating speed of the input shaft of the gearbox.
In one embodiment, the target required position offset, that is, the target required position offset = (K-K0)/K0 × the target rotation speed of the transmission input shaft, may also be determined according to the maximum position correction coefficient, the target position correction coefficient, and the target rotation speed of the transmission input shaft. K is the maximum position correction coefficient, K0 is the target position correction coefficient, and K0 can be determined according to the rotating speed of the input shaft of the gearbox.
After the target required position offset is determined, the step S303 is continuously executed to perform secondary speed regulation. And repeating the speed regulation process until the absolute value of the difference between the current rotating speed of the input shaft of the gearbox and the target rotating speed of the input shaft of the gearbox is not greater than the set threshold value, and then executing the gear engaging operation.
Optionally, after the vehicle controller is powered off, the required position offset of the clutch may be automatically stored to be used as the required position offset of the clutch in the next speed regulation process, so as to participate in the calculation of the target position.
In the control mode, the states of all parts of the vehicle can be as shown in fig. 4, the clutch is closed instantaneously in the gear engaging process, accurate speed regulation gear engaging is realized, the clutch is closed slowly after gear engaging is finished, and the whole vehicle starts to run in an accelerated manner.
According to the control method for the rotating speed of the input shaft of the gearbox, after the starting and gear engaging state of a vehicle in a pure engine mode is determined, and the current gear of the vehicle is in a neutral gear, the stored historical required position offset of the clutch is obtained, the target position of the clutch is determined according to the historical required position offset and the required position of the clutch, the clutch is controlled to be engaged to the target position, in the engaging process, the current rotating speed of the input shaft of the gearbox is obtained at set time intervals, gear engaging operation is executed when the absolute value of the difference between the current rotating speed and the target rotating speed is determined to be not larger than a set threshold, the maximum rotating speed of the input shaft of the gearbox is obtained when the absolute value of the difference between the current rotating speed and the target rotating speed is determined to be larger than the set threshold, the current required position offset obtained through recalculation according to the maximum rotating speed and the target rotating speed is repeated, and gear engaging operation is executed until the absolute value of the difference between the current rotating speed and the target rotating speed is not larger than the set threshold. Because the required position offset of the clutch can be converted into a calculated value from a fixed value through the rotating speed and the target rotating speed of the input shaft of the gearbox, the self-adaptive adjustment of the required position offset of the clutch is realized, manual debugging is replaced, the numerical precision is improved, and the calibration time is saved. In addition, the required position offset of the clutch can be changed along with the position of the sliding mode of the clutch by optimizing the required position offset of the clutch, the control precision of the sliding mode position of the clutch in the starting and gear engaging stage of a vehicle in a pure engine mode is improved, and the accurate adjustment of the rotating speed of the input shaft of the gearbox without the synchronizer is realized, so that the speed regulation time is shortened, and the success rate of the first gear engaging is improved.

Because the device is a device corresponding to the method for controlling the rotating speed of the input shaft of the gearbox, and the principle of solving the problem of the device is similar to that of the method, the implementation of the device can refer to the implementation of the method, and repeated parts are not described again.
