It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1 is a flowchart of a running-in method of an automatic transmission according to a first embodiment of the present invention, where the method is applicable to a running-in situation of the automatic transmission during offline detection, and the method may be executed by a running-in device of the automatic transmission, and the device may be implemented in software and/or hardware, and the device may be configured in a device, for example, the device may be a smart phone, a computer, or a tablet computer.
Fig. 2 is a schematic diagram of a running-in table of an automatic transmission in a first embodiment of the present invention, referring to fig. 2, the running-in table of the automatic transmission in the present embodiment may include an automatic transmission 11, a driving motor 12 and a load motor 13, wherein the driving motor 12 may simulate an engine on a vehicle and mainly takes charge of outputting torque and rotating speed, the load motor 13 may simulate a vehicle load, and the automatic transmission 11 is a controlled object in a running-in process.
Fig. 3 is a schematic diagram of a controlled mechanism in an automatic transmission according to a first embodiment of the present invention, and referring to fig. 3, the controlled mechanism in the automatic transmission according to the present embodiment may include a synchronizer cone 111 and a synchronizer ring 112, wherein the synchronizer ring 112 may include a friction pair therein. The synchronizer cone 111 has a cone angle α and a cone average diameter d. The conical surface of the synchronizer cone 111 can comprise a single conical surface and a plurality of conical surfaces, the shifting force F can be the pressure provided by the shifting solenoid valve, and the specific pressure value can be obtained by the calculation of the solenoid valve characteristic curve look-up table.
Since the shift pressure of the automatic transmission in the present embodiment can be realized by using a solenoid valve, such as a vbs (variable Bleed solenoid) solenoid valve, the shift pressure can be adjusted by adjusting the magnitude of the solenoid current. The current of the solenoid valve may be set according to the frictional force and the frictional torque of the synchronizer ring 112 and the synchronizer cone 111 in this embodiment to set the shift pressure. The normal force of the friction surfaces of the synchronizer cone 111 and the synchronizer ring 112 can be calculated by the formula

Is calculated to obtain, wherein TRThe torque represents friction torque, mu represents the dynamic friction coefficient of a friction pair, j represents a conical surface of a synchronizer, j is 1 in a single conical surface, and j is more than or equal to 2 in a multi-conical surface.
As shown in fig. 1, the method may specifically include:
and S110, acquiring a running-in instruction.
The running-in command is a command for realizing running-in of the automatic transmission. Specifically, the specific manner in which the running-in device of the automatic transmission acquires the running-in instruction may be set according to an actual situation, for example, the running-in device of the automatic transmission detects a trigger operation of a user on a setting key, which may be a physical key or a virtual key, and then determines to acquire the running-in instruction; for another example, when the running-in device of the automatic transmission receives a preset voice instruction or a preset gesture operation of a user, the running-in device can determine to obtain the running-in instruction, where the preset voice instruction and the preset gesture operation can be set according to an actual situation.
In addition, after the running-in instruction is acquired, the method further comprises the following steps: and judging whether the running-in condition is met. The running-in condition may be whether or not relevant devices, such as a clutch solenoid valve, a gear engaging and disengaging solenoid valve, a clutch pressure sensor, a shift fork position sensor, and the like of the automatic transmission are in a normal state when the automatic transmission is in a running-in state. If the related devices have electrical faults when the automatic transmission is in running-in, the running-in is directly quitted after the running-in failure, and if the related devices are in a normal state, the subsequent operation is executed.
And S120, determining a target running-in gear according to the running-in command.
The target running-in gear is any one of gears included in the vehicle, and the target running-in gear can include 1-7 gears and a reverse gear.
Specifically, after the running-in command is obtained by the running-in device of the automatic transmission, the target running-in gear can be determined based on the selection of the user, and the target running-in gear can also be automatically determined. For example, the running-in apparatus of the automatic transmission may automatically determine the target running-in gear in order of 1 st gear, 2 nd gear, 3 rd gear, 4 th gear, 5 th gear, 6 th gear, 7 th gear, and R th gear.
And S130, controlling the electromagnetic valve in the automatic transmission to apply the target current.
Wherein the target current is obtained according to the friction force and the friction torque of the synchronizer cone and the synchronizer ring and is used for providing the shifting pressure on the synchronizer ring. The target current in this embodiment may be set according to the target break-in gear, that is, the target currents of different target break-in gears are different. For example, the target current of 2 nd gear may be set to 400mA, and the target current of 3 rd gear may be set to 500 mA.
Specifically, after the running-in device of the automatic transmission determines a target running-in gear, a solenoid valve in the automatic transmission is controlled to be started, and a target current corresponding to the target running-in gear is applied.
And S140, if the synchronizer ring in the automatic transmission reaches the running-in position within the set time and the running-in time of the target running-in gear meets the target running-in time, finishing the running-in.
Wherein the set time may be a theoretical maximum time for the synchronizer ring to reach the run-in position. The theoretical longest time begins from the application of current to the electromagnetic valve, the electromagnetic valve can have certain delayed response time, then the electromagnetic valve piston pushes the shifting fork, and the shifting fork pushes the gear sleeve and the synchronizer ring to overcome certain resistance and idle stroke and also to need certain time. The theoretical maximum time in this embodiment may be set according to actual conditions.
The target running-in time can be set according to the target running-in gear, namely, the target running-in time corresponding to different target running-in gears is different. The target break-in time is related to the design capacity of the synchronizer ring, the magnitude of the frictional force between the synchronizer cone and the synchronizer ring, and the frictional material. If the target running-in time is too short, running-in is insufficient, and if the target running-in time is too long, the running-in heat is too large, and the object to be run-in, namely the synchronizer ring, is damaged.
For example, the target break-in time for gear 1 may be set to 10s, the target break-in time for gear 2 may be set to 6s, the target break-in time for gear 3 may be set to 5s, the target break-in time for gear 4 may be set to 3s, the target break-in time for gear 5 may be set to 3s, the target break-in time for gear 6 may be set to 3s, the target break-in time for gear 7 may be set to 3s, and the target break-in time for reverse gear may be set to 10 s.
Specifically, the step of enabling a synchronizer ring in the automatic transmission to reach a running-in position within a set time may include: and determining that the synchronizer ring reaches a running-in position if the torque of a driving motor connected with the automatic transmission is greater than the set torque within the set time. The running-in position can be characterized by the torque of the driving motor, the friction force is larger when the applied pressure is larger, and the transmitted torque is larger, and it can be understood that the torque of the driving motor is close to 0 when the target current is 0. The setting torque in the present embodiment may be set according to actual conditions, and for example, the setting torque may be set to 12 Nm.
Further, if a synchronizer ring in the automatic transmission reaches a running-in position within a set time and the running-in time of a target running-in gear meets the target running-in time corresponding to the target running-in gear, the running-in is completed, the running-in is stopped, and the target current of the gear shifting solenoid valve is set to be zero.
In the embodiment, the running-in instruction is acquired, the target running-in gear is determined according to the running-in instruction, the electromagnetic valve in the automatic transmission is controlled to apply the target current, and if the synchronizer ring in the automatic transmission reaches the running-in position within the set time and the running-in time of the target running-in gear meets the target running-in time, the running-in is completed. According to the technical scheme, the gear running-in of the automatic transmission is realized through running-in of the synchronizer ring in the automatic transmission, the consistency of products is effectively improved, a series of gear shifting problems caused by the characteristics of friction materials or the assembly consistency can be eliminated, and the driving feeling of the whole vehicle is improved.
Example two
Fig. 4 is a flowchart of a running-in method of an automatic transmission according to a second embodiment of the present invention. The present embodiment further optimizes the running-in method of the automatic transmission described above on the basis of the above-described embodiments. Correspondingly, as shown in fig. 4, the method of this embodiment specifically includes:
and S210, acquiring a running-in instruction.
And S220, controlling the clutch in the automatic transmission to be closed.
Specifically, after acquiring the running-in command, the running-in device of the automatic transmission may control the clutch in the automatic transmission to be closed according to the running-in command. In this embodiment, the clutch actuator is a hydraulic actuator, and therefore the pressure required for closing the clutch also needs to be calculated by looking up the current-pressure characteristic curve of the solenoid valve to obtain the driving current. If the clutch can not be closed normally, the running-in failure directly exits the running-in.
And S230, determining a target running-in gear according to the running-in command.
The target running-in gear is any one of gears included in the vehicle, and the target running-in gear can include 1-7 gears and a reverse gear.
And S240, controlling the electromagnetic valve in the automatic transmission to apply the target current.
The target current in this embodiment may be set according to the target break-in gear, that is, the target currents of different target break-in gears are different.
And S250, judging whether a synchronizer ring in the automatic transmission reaches a running-in position within set time.
Whether a synchronizer ring in an automatic transmission reaches a running-in position within a set time may include: determining that a synchronizer ring reaches a running-in position if the torque of a driving motor connected with the automatic transmission is greater than a set torque within a set time; and if the torque of a driving motor connected with the automatic transmission is less than or equal to the set torque, determining that the synchronizer ring does not reach the running-in position.
If the synchronizer ring in the automatic transmission reaches the running-in position within the set time, executing S260; if the synchronizer ring in the automatic transmission does not reach the run-in position within the set time, S270 is executed.
And S260, if the running-in time of the target running-in gear meets the target running-in time, finishing running-in.
And if the synchronizer ring in the automatic transmission reaches the running-in position within the set time and the running-in time of the target running-in gear meets the target running-in time corresponding to the target running-in gear, finishing the running-in, stopping the running-in and setting the target current of the gear shifting solenoid valve to be zero.
It needs to be understood that after the running-in of each target running-in gear is completed, whether all gears are completely run-in needs to be judged, if not, the determination of a new target running-in gear is continuously executed, and the running-in of the new target running-in gear is carried out; and if the running-in is finished, ending the running-in.
And S270, controlling the electromagnetic valve to increase the set current on the basis of the target current.
If a synchronizer ring in the automatic transmission does not reach a running-in position within a set time, the control solenoid increases a set current based on the target current to increase a shift pressure. The set current may be a current value that is theoretically allowed to be increased, and may be set according to an actual situation, which is not limited in this embodiment. For example, the set current may be set to 100 mA.
And S280, if the synchronizer ring does not reach the running-in position within the set time, determining that the automatic transmission is unqualified and exiting the running-in.
Specifically, after the solenoid valve increases the set current on the basis of the target current, the synchronizer ring does not reach the running-in position within the set time, and it is determined that the automatic transmission is unqualified and the running-in is exited.
In addition, if the pressure is too high during the running-in process, the transmission torque is too high, and damage may be caused to a running-in object, i.e., a synchronizer ring of the automatic transmission. In the process of running-in of the automatic transmission, if the torque of the driving motor is detected to be larger than a torque threshold value, it is determined that the gear shifting pressure is too large or a mechanical fault occurs, and the running-in needs to be timely quitted. The torque threshold may be set according to actual conditions, for example, the torque threshold in the present embodiment may be set to 10 Nm. And, should the clutch accidentally disengage or the solenoid valve otherwise fail during break-in be detected, immediate break-in may be required.
In the embodiment, a running-in instruction is obtained, a clutch in an automatic transmission is controlled to be closed, a target running-in gear is determined according to the running-in instruction, a solenoid valve in the automatic transmission is controlled to apply a target current, and if a synchronizer ring in the automatic transmission reaches a running-in position within a set time and the running-in time of the target running-in gear meets the target running-in time, the running-in is completed; and if the synchronizer ring in the automatic transmission does not reach the running-in position within the set time, the control solenoid valve increases the set current on the basis of the target current, and if the synchronizer ring does not reach the running-in position within the set time, the automatic transmission is determined to be unqualified and the running-in is exited. According to the technical scheme provided by the embodiment of the invention, the gear running-in of the automatic transmission is realized by running-in of the synchronizer ring in the automatic transmission, the consistency of products is effectively improved, a series of gear shifting problems caused by the characteristics of friction materials or the assembly consistency can be eliminated, the gear shifting quality is optimized, the gear shifting force is reduced, the gear shifting time is shortened, and the driving feeling of the whole vehicle is improved.
