[0063] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0064] Example 1

[0065] Please see Figure 1 , Figure 1 This is a flowchart illustrating a method for calculating the amount of fuel dispensed in an air-cooled automatic transmission, as disclosed in an embodiment of this application. Figure 1 As shown, the method in this application embodiment includes the following steps:

[0066] 101. Calculate the total oil volume of the transmission hydraulic control system when the transmission is operating normally;

[0067] 102. Calculate the total oil volume of the cooling and lubrication system and the hydraulic system of the torque converter when the transmission is operating normally;

[0068] 103. Calculate the amount of oil in the cavity below the target oil level;

[0069] 104. Based on the oil volume in the cavity below the target oil level, the total oil volume of the transmission hydraulic control system when the transmission is working normally, and the total oil volume of the cooling lubrication system and the hydraulic torque converter hydraulic system when the transmission is working normally, determine the amount of oil to be added to the air-cooled automatic transmission.

[0070] 105. Obtain the fluid outflow data from the transmission fluid level port under actual operating conditions;

[0071] 106. Adjust the amount of oil added to the air-cooled automatic transmission based on the oil flow data from the transmission oil level port under actual operating conditions.

[0072] The embodiment of the present application calculates the total oil amount of the transmission hydraulic control system when the transmission is normally working, calculates the total oil amount of the cooling and lubricating system and the hydraulic torque converter hydraulic system when the transmission is normally working, and calculates the cavity oil amount below the target oil level surface. Then, the oil filling amount of the air-cooled automatic transmission can be determined based on the cavity oil amount below the target oil level surface, the total oil amount of the transmission hydraulic control system when the transmission is normally working, and the total oil amount of the cooling and lubricating system and the hydraulic torque converter hydraulic system when the transmission is normally working. On the other hand, by obtaining the oil outflow data of the transmission oil level port under real working conditions, the oil filling amount of the air-cooled automatic transmission can be adjusted based on the oil outflow data of the transmission oil level port under real working conditions, so as to improve the calculation accuracy of the oil filling amount of the air-cooled automatic transmission.

[0073] In the embodiment of the present application, for the air-cooled automatic transmission, the oil not only circulates inside the transmission, but also circulates outside the transmission. Therefore, in order to meet the demand, the oil amount of the air-cooled automatic transmission includes the oil amount required by the transmission hydraulic control system and the oil amount required by the cooling and lubricating system and the hydraulic torque converter hydraulic system. In addition, a redundant oil amount is usually stored in the oil pan, which is used for circulation. Therefore, the oil filling amount of the air-cooled automatic transmission needs to be determined by the cavity oil amount below the target oil level surface, the total oil amount of the transmission hydraulic control system when the transmission is normally working, and the total oil amount of the cooling and lubricating system and the hydraulic torque converter hydraulic system when the transmission is normally working.

[0074] In the embodiment of the present application, the total oil amount of the transmission hydraulic control system when the transmission is normally working refers to the oil amount required by the transmission hydraulic control system when the transmission is normally working.

[0075] In the embodiment of the present application, the cooling and lubricating system and the hydraulic torque converter hydraulic system usually work cooperatively, so the cooling and lubricating system and the hydraulic torque converter hydraulic system can be regarded as a total system.

[0076] In the embodiment of the present application, the inside of the oil pan is designed as a cavity for storing transmission oil. The transmission oil can form a target oil level surface in the cavity, and the oil amount below the target oil level surface is referred to as the cavity oil amount below the target oil level surface.

[0077] In the embodiment of the present application, steps 101, 102 and 103 are realized based on simulation analysis, therefore, the oiling amount of the air-cooled automatic transmission calculated by step 104 is a theoretical value, which may be different from the actual value, therefore, in order to reduce the difference between the two, the oiling amount of the air-cooled automatic transmission calculated by step 104 needs to be corrected based on the oil outflow data of the transmission oil level port under real working conditions, wherein the oil outflow data of the transmission oil level port under real working conditions reflects the difference between the two, for example, if the oiling amount of the air-cooled automatic transmission calculated by step 104 is the same as the actual value, theoretically, when the air-cooled automatic transmission is filled with oil according to the oiling amount calculated by step 104, the transmission hydraulic control system, the cooling and lubricating system and the hydraulic torque converter hydraulic system are fully filled with oil, and then the transmission oil can overflow from the transmission oil level port, and if the oiling amount of the air-cooled automatic transmission calculated by step 104 is less than the actual value, the transmission oil cannot overflow from the transmission oil level port. Further, if the transmission oil overflows from the transmission oil level port, the oiling amount of the air-cooled automatic transmission calculated by step 104 can be reduced according to the overflow amount, so that the transmission oil just overflows the transmission oil level port. If the transmission oil is still not enough to overflow from the transmission oil level port, the transmission oil level port is filled with oil, so that the transmission oil just overflows the transmission oil level port, and then the oiling amount of the air-cooled automatic transmission calculated by step 104 is adjusted according to the oiling amount, so as to finally improve the calculation accuracy of the oiling amount of the air-cooled automatic transmission.

[0078] In the embodiment of the present application, in order to obtain the oil outflow data of the transmission oil level port under real working conditions, the real working conditions need to be realized, and the specific process is as follows: first, start the engine, the engine drives the hydraulic torque converter shell, drives the oil pump to rotate, the cooling and lubricating system and the hydraulic torque converter hydraulic system start to fill oil, and the transmission oil temperature also rises, when the oil temperature rises to the opening temperature of the temperature control valve, the temperature control valve opens, the air-cooled cooler is filled with oil, and the cooling oil channel is filled with oil. Engage R gear and D gear for several seconds, so that the hydraulic control system clutch and brake are filled with oil. Engage N gear, and let the engine speed rise for several seconds, so that the hydraulic torque converter hydraulic system is filled with oil. At this time, the internal oil circuit system of the transmission is filled with oil, engage P gear, so that the parking mechanism is filled with oil, and the engine idles.

[0079] Further, open the transmission oil level port, and confirm whether the oiling amount meets the requirements. If a small amount of oil flows out, the oiling amount is accurate. If no oil flows out, add oil until it flows out, record the oiling amount, and confirm the final accurate oiling amount by comprehensively confirming the calculated value.

[0080] In the embodiments of the present application, as an optional implementation, the step of adjusting the oiling amount of the air-cooled automatic transmission based on the oil outflow data of the transmission oil level port under the real working condition comprises the following steps:

[0084] The optional implementation can judge whether the transmission oil level port has oil outflow under the real working condition based on the oil outflow data of the transmission oil level port under the real working condition, and then keep the oiling amount of the air-cooled automatic transmission unchanged when the transmission oil level port has oil outflow under the real working condition, and increase the oiling amount of the air-cooled automatic transmission when the transmission oil level port has no oil outflow under the real working condition.

[0085] In the embodiments of the present application, as an optional implementation, the step of increasing the oiling amount of the air-cooled automatic transmission comprises:

[0092] The optional embodiment can simulate and analyze the transmission oil filling flow of the first oil filling process and the oil filling time of the first oil filling process, and then can calculate the total oil amount of the transmission hydraulic control system when the transmission is normally working based on the transmission oil filling flow of the first oil filling process and the oil filling time of the first oil filling process, wherein the first oil filling process is a process of filling the transmission hydraulic control system when the air-cooled mode automatic transmission is normally working.

[0093] For the optional embodiment, the first oil filling process is based on the transmission hydraulic control system, wherein the transmission hydraulic control system includes an oil sump, a suction filter, a double-vane pump, a hydraulic valve body, a hydraulic control oil circuit, a brake, a clutch, a parking mechanism and the like. Further, referring to Figure 2 , Figure 2 is a schematic diagram of a principle of a transmission hydraulic control system disclosed in an embodiment of the present application. As shown in Figure 2 , the first oil filling process specifically refers to that the transmission oil is filtered by the suction filter after being pumped from the oil sump by the double-vane pump and then enters the hydraulic valve body, the hydraulic valve body performs oil circuit distribution and pressure control, and the transmission oil flows to the clutch and brake pistons, the parking lock hydraulic valve and the like. Further, by controlling the clutch and the parking lock to be combined and separated, the transmission gear shifting and parking functions are realized.
