Description

[0002] Precise control of clutch pressure is crucial for precise control of a dual-clutch automatic transmission, and in a low-temperature state, especially when a low-temperature vehicle is started for the first time, the actual pressure follows poorly when the controller controls the clutch pressure due to the large viscosity of the oil, thereby causing a large delay when the vehicle starts, greatly affecting the driving experience.

[0003] Currently, when compensating for low-temperature oil pressure of a clutch, a stable control compensation value is calculated based on the current temperature, so that the clutch pressure control is more precise. However, since the compensation value is a steady-state compensation, the pressure state is changing in real time during the entire clutch pressure control process, and the clutch pressure delay is different at each stage, so it is difficult to achieve optimal pressure control.

[0026] Embodiment one

[0027] Figure 1 A flow chart of a pressure compensation method of a clutch provided by the first embodiment of the present application, the present embodiment can be applied to the case of dynamically compensating the pressure of the clutch, and the method can be executed by the pressure compensation device of the clutch in the embodiments of the present application, which can be realized in the form of hardware and / or software. As shown in the figure, the method comprises: Figure 1

[0028] Step S101, when it is determined that the current environment temperature and the clutch oil temperature are both less than the set value, enter the clutch pressure dynamic compensation mode.

[0029] ​Specifically, in the embodiment, the clutch pressure dynamic compensation of the clutch of the dual-clutch automatic transmission is mainly performed in the low-temperature oil filling stage. Therefore, after the vehicle is powered on, the current ambient temperature and the clutch oil temperature are collected. In the embodiment, the set value is configured in advance, and the collected current ambient temperature and clutch oil temperature are compared with the set value. When it is determined that the ambient temperature and the clutch oil temperature are both less than the set value, the clutch pressure dynamic compensation mode is entered. In the clutch pressure dynamic compensation mode, various compensation modes can be included, such as pulse dynamic pressure compensation and steady-state pressure fixed compensation. The pulse dynamic pressure compensation can be divided into pulse dynamic pressure positive compensation and pulse dynamic pressure negative compensation. The embodiment does not limit the specific compensation modes included in the clutch pressure dynamic compensation mode.

[0030] In the embodiment, the current ambient temperature and the clutch oil temperature can be obtained by a temperature sensor. Specifically, the current ambient temperature can be obtained by a first temperature sensor arranged on the surface of the vehicle, and the clutch oil temperature can be obtained by a second temperature sensor arranged at the clutch position. In order to ensure the accuracy of data collection, multiple values in a continuous unit time can be obtained, and the average value of the multiple values can be calculated. The obtained average value is used as the temperature or oil temperature collected at the current time. Of course, the embodiment is only an example, and the specific way of collecting values is not limited. As long as the accuracy of the collected data is ensured, it is within the protection scope of the application, and the embodiment does not repeat it.

[0031] In step S102, the operating parameters of the clutch are obtained in the clutch pressure dynamic compensation mode.

[0032] Optionally, in the clutch pressure dynamic compensation mode, the operating parameters of the clutch are obtained, including monitoring the operation of the clutch in the clutch pressure dynamic mode, and obtaining the operating parameters of the clutch according to the monitoring result. The operating parameters include the clutch target pressure, the clutch actual pressure, the clutch target pressure change rate, and the clutch actual pressure change rate.

[0033] Specifically, when the clutch pressure dynamic compensation mode is entered in the embodiment, the operating parameters of the clutch are acquired in the mode, and specifically, the operating process of the clutch is monitored, and the operating parameters are acquired according to the monitoring result. The operating parameters include the clutch target pressure, the clutch actual pressure, the clutch target pressure change rate, the clutch actual pressure change rate, and the like. Of course, the embodiment is only used for illustration, and the specific type of the operating parameters is not limited. In the embodiment, it can be determined based on the acquired operating parameters which compensation mode is used in the clutch pressure dynamic compensation mode.

[0034] It should be noted that, since the operating parameters of the clutch are collected in real time, not only the data in the current period are collected and recorded, but also the clutch target pressure and the clutch actual pressure before the specified period are recorded, so as to ensure the integrity of the data record.

[0035] In step S103, when the operating parameters meet the preset condition, the compensation interval and the compensation value of the clutch are acquired in real time.

[0036] Optionally, when the operating parameters meet the preset condition, the compensation interval and the compensation value of the clutch are acquired in real time, including: when it is determined that the difference between the clutch target pressure and the clutch actual pressure is greater than a specified threshold and lasts for a specified duration, or the clutch target pressure change rate is greater than the clutch actual pressure change rate, it is determined that the operating parameters meet the preset condition; the compensation interval is acquired in real time according to the operating parameters, and the compensation value is acquired in real time according to the clutch oil temperature.

[0037] Specifically, in the embodiment, it is determined based on the acquired operating parameters which compensation mode is used in the clutch pressure dynamic compensation mode, and in the embodiment, the preset condition corresponding to the pulse type dynamic pressure compensation is set, and when the operating parameters meet the preset condition, the pulse type dynamic pressure compensation is used. Since the pulse type dynamic pressure compensation can be divided into pulse type dynamic pressure positive compensation and pulse type dynamic pressure negative compensation, when it is determined that the clutch actual pressure is less than the clutch target pressure, the pulse type dynamic pressure positive compensation is used; when it is determined that the clutch actual pressure is greater than the clutch target pressure, the pulse type dynamic pressure negative compensation is used. Since the principles of the pulse type dynamic pressure positive compensation and the pulse type dynamic pressure negative compensation for pressure compensation are roughly the same, only the specific process of the pulse type dynamic pressure positive compensation is described in the embodiment.

[0038] It should be noted that when it is determined that the difference between the clutch target pressure and the clutch actual pressure is greater than the specified threshold value and lasts for a specified duration, or the clutch target pressure change rate is greater than the clutch actual pressure change rate, it is determined that the operating parameter meets the preset condition, that is, the condition for pulse dynamic pressure compensation is met, at this time, the compensation interval is further obtained in real time according to the operating parameter obtained above, and the way of obtaining the compensation interval is different for different situations. For example, when it is determined that the difference between the clutch target pressure and the clutch actual pressure is greater than the specified threshold value and lasts for a specified duration, the first difference between the clutch target pressure and the clutch actual pressure is calculated, the compensation interval is obtained according to the first difference and the first type of compensation interval list, and since the corresponding relationship between the pressure difference and the compensation interval is included in the first type of compensation interval list, the compensation interval can be obtained by querying the first type of compensation interval list. When it is determined that the clutch target pressure change rate is greater than the clutch actual pressure change rate, the second difference between the clutch target pressure change rate and the clutch actual pressure change rate is calculated, and the compensation interval is obtained according to the second difference and the second type of compensation interval list, and since the corresponding relationship between the pressure change rate difference and the compensation interval is included in the second type of compensation interval list, the compensation interval can be obtained by querying the second type of compensation interval list. Of course, the above two different situations are only used as examples to illustrate the specific way of obtaining the compensation interval in the embodiment, and the specific way of obtaining the compensation interval is not limited.

[0039] In addition, in the embodiment, after the compensation interval is obtained, a specific compensation value can also be obtained according to the clutch oil temperature, and specifically, a pre-set compensation value list is obtained, wherein the compensation value list includes the corresponding relationship between the clutch oil temperature and the compensation value; the compensation value corresponding to the clutch oil temperature is obtained by querying the compensation value list according to the clutch oil temperature. Of course, the above is only used as an example, and the specific way of obtaining the compensation value is not limited, for example, the compensation value can also be calculated according to the clutch oil temperature, and the specific calculation formula for obtaining the compensation value according to the clutch oil temperature is not limited in the embodiment, and the user can set it according to the actual situation.

[0040] In step S104, the clutch is compensated by pulse dynamic pressure based on the compensation interval and the compensation value.

[0041] Optionally, the clutch is compensated by pulse dynamic pressure based on the compensation interval and the compensation value, including: determining a compensation time point based on the compensation interval; and compensating the clutch actual pressure with the compensation value at the compensation time point, so that the compensated clutch actual pressure follows the clutch target pressure.

[0042] Specifically, after the compensation interval and the compensation value are obtained in the embodiment, the clutch is subjected to pulse dynamic pressure compensation, and when the compensation is performed, a compensation time point is determined based on the compensation interval, and each compensation time is set as Δt, the controller has a control period T, and therefore the pressure rise value per control period is (compensation value*T) / (2*Δt), and when the clutch command control pressure reaches (compensation value+clutch target pressure), the pressure is decreased by a gradient of (compensation value*T) / (2*Δt) per control period until the clutch target pressure is reached, the compensation cycle is ended, and the above compensation operation is repeated after Δt, so as to control the pressure of the clutch.

[0043] It should be noted that, in the embodiment, when it is determined that the difference between the clutch target pressure and the actual pressure of the clutch in the current period is less than the difference between the clutch target pressure and the actual pressure of the clutch before the specified period, it is indicated that the pulse dynamic pressure compensation is not applicable at present, and therefore the clutch is subjected to steady-state pressure fixed compensation, and when the compensation is performed, only a fixed compensation value needs to be obtained, and the clutch is subjected to steady-state pressure fixed compensation by using the fixed compensation value. For example, after the fixed compensation value is calculated according to the difference between the clutch target pressure and the actual pressure of the clutch before the specified period, the clutch command pressure is equal to the sum of the clutch target pressure and the fixed compensation value, until the difference between the clutch target pressure and the actual pressure of the clutch before the specified period is less than a set value, and then the clutch pressure compensation is exited. Of course, the embodiment is only an example, and the specific manner of the steady-state pressure fixed compensation is not limited.

[0044] In the embodiment, the compensation interval and the compensation value of the clutch are obtained in real time according to the obtained operating parameters of the clutch, and the pulse dynamic compensation is performed on the oil charging process of the clutch according to the compensation interval and the compensation value, so that the pressure compensation is performed in real time according to the current oil charging process, and the problems of poor pressure response and inaccurate following of the low-temperature clutch are effectively solved.

[0045] Embodiment Two

[0046] Figure 2 A flowchart of a pressure compensation method of a clutch provided in the embodiment two, and the embodiment is based on the above-mentioned embodiment, and after the pulse dynamic pressure compensation is performed on the clutch according to the compensation interval and the compensation value, the pressure compensation result of the clutch is detected. As shown in the method, the method comprises the following steps. Figure 2

[0047] In step S201, when it is determined that the current environment temperature and the oil temperature of the clutch are both less than a set value, the clutch pressure dynamic compensation mode is entered.

[0048] In step S202, the operating parameters of the clutch are obtained in the clutch pressure dynamic compensation mode.​

[0049] Optionally, the operation parameter of the clutch is acquired in the clutch pressure dynamic compensation mode, comprising: monitoring the operation of the clutch in the clutch pressure dynamic mode; and acquiring the operation parameter of the clutch according to the monitoring result, wherein the operation parameter comprises the clutch target pressure, the clutch actual pressure, the clutch target pressure change rate and the clutch actual pressure change rate.

[0050] Step S203, when the operation parameter meets the preset condition, the compensation interval and the compensation value of the clutch are acquired in real time.

[0051] Optionally, when the operation parameter meets the preset condition, the compensation interval and the compensation value of the clutch are acquired in real time, comprising: when it is determined that the difference between the clutch target pressure and the clutch actual pressure is greater than a specified threshold and lasts for a specified duration, or the clutch target pressure change rate is greater than the clutch actual pressure change rate, it is determined that the operation parameter meets the preset condition; the compensation interval is acquired in real time according to the operation parameter, and the compensation value is acquired in real time according to the clutch oil temperature.

[0052] Step S204, the clutch is compensated in a pulse dynamic pressure mode based on the compensation interval and the compensation value.

[0053] Optionally, the clutch is compensated in a pulse dynamic pressure mode based on the compensation interval and the compensation value, comprising: determining a compensation time point based on the compensation interval; and compensating the clutch actual pressure with the compensation value at the compensation time point, so that the compensated clutch actual pressure follows the clutch target pressure.

[0054] Step S205, the pressure compensation result of the clutch is detected.

[0055] Specifically, after the clutch is compensated in a pulse dynamic pressure mode in the embodiment, the difference between the clutch actual pressure and the clutch expected pressure after the clutch receives the command control pressure is calculated, and it is determined whether the difference is less than a preset threshold. When it is determined that the difference is less than the preset threshold, it is indicated that the subsequent clutch actual pressure can quickly follow the clutch target pressure through pressure compensation, so that it is determined that the current pressure compensation is effective. When it is determined that the difference is greater than the preset threshold, it is indicated that the subsequent clutch actual pressure cannot quickly follow the clutch target pressure through pressure compensation, i.e. the clutch pressure is delayed.

[0056] It should be noted that when it is determined that the pulse dynamic pressure compensation is invalid, an alarm information is generated, and an alarm prompt is performed in a specified manner, for example, an alarm is performed in a voice manner or an alarm is performed in a lamp tube flickering manner. Of course, the embodiment is only an example, and the specific manner of the alarm prompt is not limited. As long as the alarm prompt can prompt the user, it is within the protection scope of the application.

[0057] It is worth mentioning that the alarm information is also sent to the mobile terminal of the user in the embodiment, so that even when the user is not near the device and cannot see the alarm information, the pressure compensation state of the clutch can be obtained in time according to the alarm information pushed to the mobile terminal, and the software or hardware of the device is repaired in the case of determining that the pressure compensation is invalid, so as to further improve the efficiency and accuracy of the clutch pressure compensation.

[0058] In the embodiment, the compensation interval and the compensation value of the clutch are obtained in real time according to the obtained operating parameters of the clutch, and the oil filling process of the clutch is dynamically compensated in pulses based on the compensation interval and the compensation value, so that the pressure compensation is realized in real time according to the current oil filling process, and the problems of poor pressure response and inaccurate following of the low-temperature clutch are effectively solved.
