It should be noted that the embodiments and features of the embodiments of the present disclosure may be combined with each other without conflict.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure, but the present disclosure may be practiced in other ways than those described herein; it is to be understood that the embodiments disclosed in the specification are only a few embodiments of the present disclosure, and not all embodiments.
In the vehicle gear shifting process, after the TCU carries out self-adaptive adjustment on an adjusting component of the automatic transmission, the adjusting value of the adjusting component is stored in a storage medium of the TCU for the TCU to read and use in the next gear shifting process. Therefore, the adjustment value of the adjustment component stored in the storage medium of the TCU needs to have high accuracy, otherwise, during the next gear shifting process, the phenomena of gear shifting impact, jerk, shake and the like may occur, which affects the driving experience of the user.
According to the method, after a gear shifting starting signal is received, the state value of an oil cut signal is acquired in real time; if the state value of the acquired fuel cut-off signal changes at least once before the gear shifting end signal is received, setting the self-adaptive interrupt signal as a preset value; after the gear shifting end signal is received, whether the first adjusting value of the adjusting component of the automatic transmission stored in the storage medium of the TCU is updated according to the second adjusting value of the adjusting component of the automatic transmission is determined according to the self-adaptive interrupt signal, so that the accuracy of the adjusting value in the storage medium of the TCU is improved, the next gear shifting process is smoother, the gear shifting smoothness is improved, the gear shifting quality is improved, and the driving experience of a user is improved.
The technical solutions of the present disclosure are described in several specific embodiments, and the same or similar concepts may be referred to one another, and are not described in detail in each place.
Fig. 1 is a schematic flowchart of an embodiment of an adaptive control method for an automatic transmission according to an embodiment of the present disclosure. The adaptive control method of the automatic transmission is applied to the shifting process of the vehicle and can be executed by a TCU. As shown in fig. 1, the method of the present embodiment includes:
s101: after receiving the shift start signal, the adjusting component of the automatic transmission is adjusted according to the first adjustment value stored by the storage medium of the TCU.
After receiving the gear-shifting starting signal, determining that the self-adaptive function of the automatic transmission is in an open state, reading a first adjusting value stored in a storage medium of the TCU, and adjusting an adjusting component of the automatic transmission according to the first adjusting value, such as: clutches, torque converters, and the like.
The storage medium of the TCU may be a charged Erasable Programmable Read-Only Memory (EEPROM). The first adjustment value comprises a combination of one or more of: clutch pressure value, torque converter pressure value, clutch disengagement duration, clutch engagement duration, and the like.
S102: a second adjustment value of an adjustment member of the automatic transmission is obtained.
Optionally, the adjusting component of the automatic transmission is adjusted according to the state of the automatic torque converter and the current road condition information of the vehicle, and a second adjusting value of the adjusting component of the automatic transmission is obtained.
S103: and acquiring the state value of the fuel cut-off signal in real time.
Optionally, the state value of the fuel cut-off signal includes: a fuel cut-off state and a fuel supply state. For example: setting the state value of the fuel cut-off signal to be 1 to represent the fuel cut-off state; setting the state value of the fuel cut signal to 0 indicates the fuel supply state.
S104: and if the state value of the acquired fuel cut-off signal changes at least once before the gear shifting end signal is received, setting the self-adaptive interrupt signal as a preset value.
Optionally, the at least one change in the state value of the fuel cut signal includes: and changing from the fuel cut-off state to the fuel supply state, or changing from the fuel supply state to the fuel cut-off state.
The preset values can be set according to actual needs, for example: 0. 1, etc., to which the present disclosure is not limited.
For example, if the state value of the acquired fuel cut signal is changed from the fuel cut state to the fuel supply state before the gear shift end signal is received, the adaptive interrupt signal is set to the preset value 1.
The scenario in which the state value of the fuel cut signal changes may include:
when the rotating speed of the engine exceeds the set highest rotating speed, fuel injection is interrupted, and the state value of the fuel cut-off signal is changed from the fuel supply state to the fuel cut-off state;
or,
when the vehicle suddenly decelerates in the process of high-speed running, fuel injection is interrupted, the state value of the fuel cut-off signal is changed from the fuel supply state to the fuel cut-off state, fuel supply is resumed until the rotating speed of the transmitter is reduced to the set low rotating speed, and the state value of the fuel cut-off signal is changed from the fuel cut-off state to the fuel supply state.
S105: after receiving the shift end signal, determining whether to update the first adjustment value stored by the storage medium of the TCU according to the second adjustment value according to the adaptive interrupt signal.
One possible implementation is: as shown in figure 2 of the drawings, in which,
s1051: and after receiving the gear shifting end signal, judging whether the self-adaptive interrupt signal is a preset value or not.
If the adaptive interrupt signal is a preset value, executing S1052; if the adaptive interrupt signal is not the preset value, S1053 is performed.
S1052: the first adjustment value stored by the storage medium of the TCU is not updated according to the second adjustment value.
For example: the timing at which the shift start signal is received is t1, the timing at which the shift end signal is received is t2, and the writing of the second adjustment value of the adjusting part of the automatic transmission between t1 and t2 to the storage medium of the TCU, which still stores the first adjustment value, is prohibited.
S1053: the first adjustment value stored by the storage medium of the TCU is updated according to the second adjustment value.
For example: the timing at which the shift start signal is received is t1, the timing at which the shift end signal is received is t2, the second adjustment value of the adjustment member of the automatic transmission between t1 and t2 is allowed to be written in the storage medium of the TCU, and the first adjustment value stored in the storage medium of the TCU is updated to the second adjustment value.

According to the self-adaptive interrupt signal, whether the second adjusting value of the adjusting part of the automatic transmission updates the first adjusting value stored in the storage medium of the TCU or not in the gear shifting process is controlled, so that the accuracy of the adjusting value in the storage medium of the TCU is improved, the next gear shifting process is smoother, the gear shifting smoothness is improved, the gear shifting quality is improved, and the driving experience of a user is improved.
Optionally, the present disclosure does not limit the order in which the TCU executes S102, S103, and S104.
Optionally, after receiving the shift end signal, the adaptive interrupt signal is set to a default value, where the default value is different from the preset value, and may be set according to actual needs, for example, the default value is 0, and the preset value is 1.

s1041: and if the state value of the acquired fuel cut signal changes for the first time before the gear shifting end signal is received, setting the self-adaptive interrupt signal as a preset value until the gear shifting end signal is received.
If the state value of the acquired fuel cut signal changes for the first time before the gear shifting end signal is received, for example: and when the oil supply state is changed to the oil cut-off state, setting the self-adaptive interrupt signal as a preset value. If the state value of the acquired fuel cut signal changes again before the gear shifting end signal is received, for example: and when the fuel supply state is recovered from the fuel cut state, the self-adaptive interrupt signal is not changed until the gear-shifting end signal is received.
In the embodiment, before the gear shifting end signal is received, the acquired state value of the oil cut signal changes for the first time, the adaptive interrupt signal is set as the preset value until the gear shifting end signal is received, the situation that the adaptive interrupt signal is repeatedly set when the oil cut signal changes for many times is avoided, the accuracy of the adjustment value in the storage medium of the TCU is improved, the next gear shifting process is smoother, the abrasion of internal parts of the automatic transmission is reduced, therefore, the gear shifting quality is improved, and the service life of the automatic transmission is prolonged.
