At present, if a reduction gearbox receives a new gear shifting request during gear shifting, one method is to execute the currently executed gear shifting request first and then execute the received new gear shifting request; another method is to interrupt the currently executing shift request and directly execute the received new shift request.
For the first gear shifting method, as the new gear shifting request is started to be executed after the gear shifting request which is executed first, the gear shifting time length is increased; in addition, since the rear axle power is cut off during the shifting, if the shifting time is long, the rear axle power cut-off time is also long, and the power performance of the whole vehicle is reduced.
With the second method, since a shift request is being executed, if a new shift request is immediately started to be executed, wear of gears in the reduction gear box may be caused, for example, if gears already engaged stop being engaged, wear may be caused.
Based on the above reasons, the present application provides a gear shift control method for a reduction gearbox, which can determine whether a new gear shift request needs to be executed immediately according to the current gear shift stage if a new gear shift request is received in the gear shift process. The application can improve the gear shifting speed compared with the prior first method. The present application avoids gear wear due to sudden stops during gear shifts, making the gear shift strategy more adaptive to the current state of the vehicle, relative to the second prior art approach.
In this embodiment, a reduction gearbox is present in the vehicle. The reduction gearbox is controlled by a shift controller (ACU) to realize shifting. Whether the shift controller performs the shift operation is determined by a Hybrid vehicle Control Unit (HCU). When a shift is required, the HUC sends a shift request to the ACU, which begins to perform a shift operation upon receiving the shift request.
The reduction gearbox can be a two-gear reduction gearbox or a four-gear reduction gearbox and the like. Three gears exist in the two-gear speed reducer, namely a neutral gear, a 1 gear and a 2 gear. For convenience of explanation, the two-speed reduction gearbox is taken as an example in the application for illustration, but the method is not limited to be used on the two-speed reduction gearbox.
Fig. 1 shows a schematic flow chart of a gear shift control method of a reduction gearbox provided by the present application, which can be implemented in the ACU described above, and with reference to fig. 1, the method is detailed as follows:
and S101, after receiving the first gear shifting request, controlling the reduction gearbox to switch gears.
In the present embodiment, the first gear shift request carries a second target gear, which is a gear to be shifted, for example, the first target gear may be 1 gear or 2 gears.
After receiving the first shift request, the first shift request is executed. The gear shifting process comprises gear shifting, motor speed regulation and gear shifting. The gear shifting is to switch the gear of the reduction gearbox to a neutral position. The motor speed regulation is carried out in a neutral position. The gear shifting is to shift the gear of the reduction gearbox from a neutral gear to a target gear.
For example, if the second target gear is the 1 st gear and the reduction gearbox is in the neutral position at the present time, the motor needs to be adjusted in speed in the neutral position, and after the speed adjustment is finished, the gear-in operation is performed. The drive operation is to drive the gear of the reduction gearbox from neutral to 1 gear.
If the second target gear is the gear 1 and the reduction gearbox is in the gear 2 at the current moment, the gear is required to be shifted from the gear 2 to the neutral gear; and then, the speed of the motor is regulated in a neutral position, and the gear is shifted after the speed regulation is finished.
S102, if a second gear shifting request is received in the gear shifting process, the gear shifting stage of the reduction gearbox at the current moment is obtained, wherein the second gear shifting request carries a first target gear.
In this embodiment, the shift stage is an off-shift stage, a motor speed regulation stage or a forward shift stage.
In the present embodiment, the first target gear and the second target gear are different gears.
S103, determining a gear shifting strategy matched with the gear shifting stages, wherein different gear shifting stages are matched with different gear shifting strategies.
In the present embodiment, different gear shifting stages are preset for different gear shifting strategies.
In some embodiments, since the gear of the reduction gearbox needs to be shifted to neutral when the second gear shift request is executed, if the current time is in the gear shifting stage, the gear shifting operation can be continuously executed, and then the second gear shift request is executed after the gear shifting is finished. Specifically, when the shift stage is a shift-off stage, the shift strategy is to execute the second shift request after the shift stage is shifted to neutral.
In some embodiments, when the second shift request is executed, the motor speed regulation is required to be performed in the neutral position, so if the current time is in the motor speed regulation stage, the speed regulation currently being executed can be ended, and the speed regulation of the second shift request can be started to be executed. Specifically, when the shift stage is the motor speed regulation stage, the shift strategy stops the speed regulation currently being executed, and starts to execute the second shift request.
In some embodiments, if the current time is in the shift stage, in order to avoid collision between gears, the shift operation needs to be continued, and the second shift request is executed after the shift operation is finished. Since the shift operation is the last step of the gear shift, when the shift stage is the shift stage, the shift strategy is to execute the second shift request after the first shift request is executed.
And S104, controlling the gear of the reduction gearbox to be switched to the first target gear according to the gear shifting strategy matched with the gear shifting stage.
Specifically, a gear shift operation is performed in accordance with the determined gear shift schedule such that the gear of the reduction gear box is finally determined at the first target gear.
In the embodiment of the application, after the first gear shifting request is received, the reduction gearbox is controlled to switch gears, if the second gear shifting request is received in the gear shifting process, the gear shifting stage of the reduction gearbox at the current moment is obtained, and the gears of the reduction gearbox are controlled to be switched to the first target gear according to the gear shifting strategy matched with the gear shifting stage. According to the method and the device, if the gear shifting request is received again in the gear shifting process, the gear shifting strategy is determined according to the gear shifting stage at the current moment, so that the gear shifting strategy is more matched with the current state of the vehicle, the gear shifting process can be more adaptive to the current state of the vehicle, and the abrasion of the vehicle during the gear shifting process is reduced.
In a possible implementation manner, after step S101, the method may further include:
and if a second gear shifting request is not received in the gear shifting process, controlling the gear of the reduction gearbox to be shifted to the second target gear.
As shown in fig. 2, in a possible implementation manner, when the shift stage is the off-shift stage, the implementation process of step S104 may include:
and S201, controlling the reduction gearbox to shift to a neutral position.
For example, if the reduction gearbox is in the 1 st gear at the current moment, the reduction gearbox is controlled to change from the 1 st gear to the neutral gear.
S202, after the reduction gearbox is in the neutral position, controlling the gear of the reduction gearbox to be switched to the first target gear.
Specifically, the neutral position is required to be switched to the target gear position during gear shifting, so that gear shifting can be continuously performed if the current time is in a gear shifting stage, the motor is started to regulate the speed after the reduction gearbox is in the neutral position, and the gear position of the reduction gearbox is shifted to the first target gear position from the neutral position after the speed regulation is finished. According to the method and the device, after the gear is shifted to the neutral position, the gear is not shifted to the gear indicated by the first gear shifting request continuously, but is shifted to the gear indicated by the second gear shifting request directly, and therefore gear shifting time is saved.
Specifically, the current rotating speed of the rear wheel of the vehicle is obtained; calculating the output rotating speed of a motor in the vehicle according to the current rotating speed; adjusting the rotation speed of the motor to the output rotation speed; and after the motor is at the output rotating speed, controlling the reduction gearbox to shift from a neutral position to the first target gear.
In this embodiment, the current rotational speed of the rear wheels of the vehicle is the average of the rotational speeds of the two rear wheels of the vehicle.
As shown in fig. 3, in a possible implementation manner, when the shift stage is the motor speed regulation stage, the implementation process of step S104 may include:
and S301, stopping the speed regulation of the motor.
In the present embodiment, since the rotation speed of the motor is changed in real time, that is, the vehicle speed of the vehicle is changed in real time, the speed regulation of the motor when the first shift request is executed is not applicable to the speed regulation of the motor when the second shift request is executed, and therefore, the speed regulation of the motor at the current time needs to be stopped first, and then the second shift request is executed.
S302, controlling the gear of the reduction gearbox to be switched to the first target gear.
In this embodiment, the process of switching the shift position in step S302 is the same as that in step S202, please refer to the description of step S202, which is not repeated herein.
As shown in fig. 4, in a possible implementation manner, when the shift stage is the shift stage, the implementation process of step S104 may include:
s401, controlling the reduction gearbox to shift to the second target gear, wherein the first gear shifting request carries the second target gear.
S402, controlling the reduction gearbox to switch the gear from the second target gear to the first target gear.
In this embodiment, since the reduction gearbox has shifted to the second target gear, when the second shift request is executed, it is necessary to first shift the transmission, then to adjust the speed of the motor, and finally shift the transmission to the first target gear.
Specifically, the implementation process of step S402 may include:
controlling the reduction gearbox to shift from the second target gear to a neutral gear;
acquiring the current rotating speed of the rear wheel of the vehicle;
calculating the output rotating speed of a motor in the vehicle according to the current rotating speed;
adjusting the rotation speed of the motor to the output rotation speed;
and after the motor is at the output rotating speed, controlling the reduction gearbox to move from the neutral gear to the first target gear.
In the embodiment of the application, since the gear of the reduction gearbox may already be engaged in the gear shifting stage, if the gear is immediately shifted to the gear shifting stage, the gear may collide to cause gear damage, and therefore, in order to protect the gear, the gear shifting needs to be completed when the reduction gearbox is in the gear shifting stage, and then the second gear shifting command is executed.
As shown in fig. 5, in a possible implementation manner, the method may further include:
and S11, receiving a first gear shifting request, and switching the gear of the reduction gearbox according to the first gear shifting request.
And S12, judging whether a second gear shifting request is received in the gear shifting process.
And S13, if the second gear shifting request is not received in the gear shifting process, the first gear shifting request is completed.
And S14, if a second gear shifting request is received in the gear shifting process, judging whether the current process is in the gear off stage.
And S15, if the current gear shifting stage is in the gear shifting stage, firstly controlling the reduction gearbox to shift to the neutral position, and then executing a second gear shifting request.
And S16, if the current process is not in the gear-off stage, judging whether the current process is in the motor speed regulation stage.
And S17, if the current speed regulation stage of the motor is in the current speed regulation stage, stopping the current speed regulation process and immediately executing a second gear shifting request.
And S18, if the current process is not in the motor speed regulation stage, judging whether the current process is in the gear shifting stage.
And S19, if the current gear is in the gear-shifting stage, continuing to execute the current process, and starting to execute a second gear-shifting request after the gear shifting is finished.
It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.
