In order to solve the above-described problems, the embodiments of the present disclosure provide a vehicle control method, which is described below in connection with specific embodiments.
Fig. 1 is a schematic flow chart of a vehicle control method according to an embodiment of the disclosure, where the method may be performed by a vehicle control device, and the device may be implemented by software and/or hardware, and may be generally integrated in an electronic device. As shown in fig. 1, the method includes:
step 101, a shift request of a vehicle is acquired.
In different application scenarios, the manner of acquiring the shift request of the vehicle is different, and examples are as follows:
In some possible embodiments, a shift key is preset in the vehicle, and when the shift key is triggered, a shift request of the vehicle is obtained;
In some possible embodiments, standard gradient information corresponding to the current gear may be detected, current gradient information corresponding to the vehicle may be obtained, whether an absolute value of a difference between the current gradient information and the standard gradient information is greater than a preset difference threshold value may be determined, and if the absolute value is greater than the preset difference threshold value, a shift request of the vehicle may be obtained.
And 102, responding to the gear shifting request, controlling the clutch to be opened and performing oil discharging treatment.
When the vehicle shifts, the clutch is required to be switched from a locking state to an opening state, and the clutch is subjected to oil discharging treatment, so that oil falls back to the oil tank.
And 103, obtaining the residual oil quantity after oil discharge treatment, and calculating the oil filling time according to the residual oil quantity.
During practical application, after oil discharge treatment, the clutch cavity and the oil duct may be insufficiently discharged, so that the clutch cavity and the oil duct are attached with oil, and at this time, in order to avoid excessive oil filling caused by re-filling when stepping on an accelerator during gear shifting, the residual oil quantity after the oil discharge treatment is obtained, and the oil filling time is calculated according to the residual oil quantity.
It should be noted that, in different application scenarios, the ways of obtaining the residual oil amount after the oil unloading treatment are different, and examples are as follows:
In some possible embodiments, a commanded oil pressure of the clutch is obtained, the commanded oil pressure being a control oil pressure generated by the processor when the clutch is shifted, a current contact point pressure of the clutch is obtained, and the amount of residual oil is determined based on the commanded oil pressure divided by the current contact point pressure of the clutch.
In some possible examples, sensor data of sensors preset in the clutch cavity and the oil passage are read, and the residual oil amount is determined according to the sensor data.
In some possible examples, the initial oil amount of the clutch is obtained, and an oil discharge duration and an oil discharge step length are determined, wherein the oil discharge duration is the total duration of performing the oil discharge treatment, that is, the duration from the start of oil discharge to the start of oil filling of the clutch, and the oil discharge step length is related to the oil discharge speed, for example, 100% of the residual oil amount of the clutch represents complete filling, and 0 represents complete discharge. The oil discharge speed is calculated by the step length of oil discharge, and when the residual oil amount of the clutch is 100%, the oil is discharged by 50 step lengths, namely 100% -0, and 500 milliseconds are needed to be discharged.
For example, the current oil discharging temperature of the clutch can be identified, the corresponding relationship between the oil discharging temperature and the oil discharging step length can be determined according to the current oil discharging temperature, for example, the corresponding relationship is determined in advance according to experimental data, and the corresponding oil discharging time length can be obtained by inquiring the corresponding relationship. For example, a driving mode before the clutch is shifted may be determined, and the oil discharging step length is determined according to the driving mode, that is, a corresponding relationship between the driving mode and the oil discharging step length is constructed in advance, and the corresponding oil discharging step length is obtained based on the corresponding relationship.
And calculating oil discharge amount according to the oil discharge duration and the oil discharge step length, calculating a first difference value between the preset oil amount and the oil discharge amount of the clutch, and determining the first difference value as residual oil amount.
Of course, considering that in some application scenarios, the oil discharge speed is accelerated, the oil discharge is relatively sufficient, the compensation processing of the oil filling time in the embodiment of the disclosure is not required to be executed, the current driving mode of the vehicle is also acquired before the residual oil quantity after the oil discharge processing is acquired according to the residual oil quantity and the oil filling time length, the oil discharge standard speed corresponding to the current driving mode is determined, and the oil discharge standard speed is determined to be smaller than or equal to the preset speed threshold.
Further, after the residual oil amount is obtained, the oil filling time period is calculated according to the residual oil amount. In this embodiment, the more the residual oil amount is, the shorter the oil filling time is, and the less the residual oil amount is, the longer the corresponding oil filling time is, so that the residual oil amount is compensated by the oil filling time, and the problem of excessive oil filling is avoided.
It should be noted that, in different application scenarios, the manner of calculating the oil-filled duration according to the residual oil amount is different, and examples are as follows:
in some possible embodiments, a preset gear shift standard oil filling amount of the clutch is obtained, wherein the preset gear shift standard oil filling amount is an oil filling amount capable of realizing smooth gear shift, the preset gear shift standard oil filling amount is calibrated in advance according to a vehicle type and the like, a second difference value between the preset gear shift standard oil filling amount and the residual oil amount is calculated, and the oil filling duration is determined according to the second difference value.
In this embodiment, considering that in the actual application scenario, the oil filling step length is related to the current oil filling temperature, the current oil filling temperature of the clutch may be identified, and the oil filling step length is determined according to the oil filling temperature. For example, a preset corresponding relation between the oil filling temperature and the oil filling step length is queried, and the corresponding relation is queried to determine the oil filling step length corresponding to the current oil filling temperature. For example, the current oil filling temperature can be input into a preset deep learning model, and the oil filling step length is obtained according to the deep learning model; for example, a sensor may be preset, an oil charge step size may be detected based on the sensor, and the like. Because the oil filling step length is related to the oil filling speed, the oil filling time length is calculated according to the second difference value and the oil filling step length. For example, the oil filling speed may be calculated according to the oil filling step length, and the ratio of the second difference value to the oil filling speed may be calculated to obtain the oil filling duration.
In some possible embodiments, a corresponding relationship between the residual oil amount and the oil filling duration may be constructed in advance according to a large amount of sample data, and after the residual oil amount is determined, the corresponding oil filling duration is determined according to the corresponding relationship, and so on.
And 104, controlling the clutch to carry out oil filling treatment according to the oil filling time.
In one embodiment of the disclosure, the clutch is controlled to be filled with oil according to the oil filling time, wherein the oil filling time is less than or equal to the default oil filling time in the conventional technology, so that the oil pressure of the clutch cannot be over-filled by calculating the residual oil quantity and the oil discharge compensation of the clutch at the previous time to compensate the oil filling time at the next time, the responsiveness of the control oil pressure and the stability of the output torque are ensured, and the comfort of the whole vehicle is improved.
Step 105, clutch lockup is controlled after the oil filling process.
In one embodiment of the present disclosure, after the oil fill process, clutch lockup is controlled to shift gears, wherein the position of lockup is related to the corresponding gear of the transmission.
Based on the above embodiment, it should be noted that, in order to ensure driving safety, it is necessary to determine that the transmission control clutch is in a preset state, the preset state is an open state, the opening of the accelerator is smaller than a preset angle threshold, the brake of the vehicle is open, and the gear of the vehicle and the clutch corresponding to the brake are the same clutch before executing the oil-filled duration determining step of the present disclosure after the gear shift request is acquired.
The following explains the vehicle control method of the present disclosure in connection with specific embodiments:
As shown in fig. 2, when the vehicle is driven in the creeping mode, the clutch is in an open state, the brake pedal is depressed, and the brake is released, so that the pressure reset of the creeping clutch is triggered, the current oil discharge temperature is detected, the oil discharge step length is determined based on the current oil discharge temperature, the oil discharge speed is determined according to the oil discharge part length, the residual oil amount after oil discharge is determined according to the oil discharge speed, the oil filling step length is obtained, the oil filling time length is calculated according to the residual oil amount and the oil filling step length, wherein the more the residual oil amount is, the shorter the corresponding oil filling time length is, the less the residual oil amount is, the corresponding oil filling time length is, and further, the oil filling treatment is carried out according to the oil filling time length, so that the compensation of the oil filling time length is realized, and the problem of excessive oil filling caused by overlong oil filling time length is avoided.
In summary, the vehicle control method according to the embodiment of the present disclosure obtains a shift request of a vehicle, responds to the shift request, controls the clutch to open and perform oil discharge treatment, obtains a residual oil amount after the oil discharge treatment, and further controls the clutch to perform oil charge treatment according to the oil charge duration, and controls the clutch to lock after the oil charge treatment. According to the technical scheme, the oil filling time is determined based on the residual oil quantity after oil discharge treatment before gear shifting, so that the oil filling time is related to the residual oil quantity, the oil filling time is compensated based on the residual oil quantity, the problem of excessive oil filling caused by overlong oil filling time is avoided, and therefore power output is stable during gear shifting, gear shifting response is more timely and comfortable, and driving experience is improved.
