[0036] During low-temperature testing and calibration, transmissions have cooling circuits, typically equipped with coolers. However, these coolers have poor heat dissipation performance at low temperatures, meaning the coolant in the cooling circuit cannot effectively cool the transmission. Therefore, an ambient chamber is usually used to directly cool the transmission housing. This cooling method is slow and inefficient. Furthermore, to ensure accuracy during low-temperature testing and calibration, the transmission's operating environment and conditions must be maintained. Natural cooling of the transmission also suffers from slow cooling rates, leading to low testing efficiency. Therefore, improving the efficiency of low-temperature testing for transmissions while maintaining accuracy has become a pressing problem.
[0037] This embodiment provides a control method for the transmission cooling system of the electronic device operating in the aforementioned vehicle. Figure 2 This is a flowchart of a control method for a transmission cooling system according to one embodiment of the present invention, such as... Figure 2 As shown, the process includes the following steps:
[0038] Step S10: Collect first operating condition parameters, wherein the first operating condition parameters are obtained by measuring the first operating state of the first branch, and the first operating condition parameters include at least: the flow rate of the coolant flowing through the cooler and the pressure of the coolant flowing through the cooler.
[0039] Step S20: Collect second operating condition parameters. The second operating condition parameters are obtained by measuring the second operating state of the second branch. The second operating condition parameters include at least: the flow rate of the coolant flowing through the heat dissipation device and the pressure of the coolant flowing through the heat dissipation device. The heat dissipation device is set differently from the cooler structure. The heat dissipation device is used to quickly cool the transmission.
[0040] Step S30: Generate control commands based on the first operating condition parameters and the second operating condition parameters;
[0041] Step S40: Adjust the second operating condition parameter based on the control command so that the adjusted second operating condition parameter and the first operating condition parameter meet the preset conditions;
[0042] The preset conditions include that the difference between the adjusted second operating condition parameter and the first operating condition parameter is less than a preset threshold.
[0043] Through the above steps, by setting up a first branch with a cooler and a second branch with a heat dissipation device, and collecting the first operating parameters of the first branch and the second operating parameters of the second branch, the second operating parameters can be adjusted using the first and second operating parameters. This allows the second branch with the heat dissipation device to quickly cool the transmission using the heat dissipation device, ensuring that the transmission's operating environment when using the heat dissipation device is consistent with its operating environment without an external heat dissipation device. This prevents changes to the transmission's operating environment, enabling rapid cooling without affecting its various operating conditions, improving test efficiency, and thus solving the technical problem of slow cooling speed in existing transmission cooling systems. In this embodiment, the heat dissipation device is a radiator with a larger heat dissipation area and the same interface as the transmission cooler. Using the technical solution of this embodiment, the transmission cooling system simulates the actual operating environment of the transmission when using the heat dissipation device, allowing the transmission cooling system to achieve the same test results in related low-temperature tests and calibrations as with natural radiation cooling, even with the heat dissipation device connected.
[0044] Optionally, the first branch and the second branch are connected in parallel. In step S10, the acquisition of the first operating condition parameters includes the following execution steps: Step S101, in response to the first branch being in the open state and the second branch being in the closed state, the first operating condition parameters are acquired.
[0045] In other words, the first operating condition parameters are collected only when the first branch is connected to the transmission. This setting can shield the influence of the second branch on the first branch, accurately measure the operating condition parameters of the transmission in a representative operating environment when there is no external interference, and realize the measurement of the actual vehicle state of the transmission.
[0046] Optionally, in step S20, collecting the second operating condition parameters includes the following execution steps: Step S201, in response to the first branch being in the open state and the second branch being in the closed state, the first operating condition parameters are collected.
[0047] Optionally, in step S30, generating control instructions based on the first operating condition parameters and the second operating condition parameters includes the following execution steps: generating adjustment factors based on the first operating condition parameters and the second operating condition parameters; generating control instructions based on the adjustment factors.
[0048] In an optional embodiment, generating control commands based on the first operating condition parameter and the second operating condition parameter may further include: calculating the difference between the first operating condition parameter and the second operating condition parameter as an adjustment factor, and generating control commands based on the difference. It should be noted that the technical solution of this embodiment does not limit the method for calculating the adjustment factor.
[0049] Optionally, the main circuit of the cooling system is sequentially equipped with an electric pump and a pressure valve, and adjusts the second operating parameters based on control commands, including: in response to the second branch being in the open state and the first branch being in the closed state, adjusting the flow rate of coolant flowing through the heat dissipation device using the pressure valve based on control commands, and / or, in response to the second branch being in the open state and the first branch being in the closed state, adjusting the pressure of coolant flowing through the heat dissipation device using the electric pump based on control commands.
[0050] Optionally, Figure 3 This is a hydraulic principle block diagram of a transmission cooling system according to one optional embodiment of the present invention. The cooling system includes: a transmission cooling oil circuit interface 1, a pressure sensor 2, a flow sensor 3, a pressure control valve 4, a three-way valve 5, a heat dissipation device 6, a vehicle cooler 7, and an electric pump 8. Using the transmission cooling system in this embodiment can significantly improve the heat dissipation capacity of the cooling system under simulated actual transmission operating conditions. When used in conjunction with a low-temperature environment chamber, it can greatly improve the efficiency of low-temperature transmission testing and calibration.
[0051] The transmission cooling oil circuit interface 1 includes an inlet end and an outlet end, which are connected by pipes that form the main circuit. Figure 3 The piping shown with the actual vehicle cooler 7 is the first branch, such as... Figure 3 The pipe shown with heat dissipation device 6 is the second branch.
[0052] Optionally, Figure 6 This is a structural block diagram of a transmission cooling system according to an optional embodiment of the present invention. The cooling system includes: a test and adjustment unit, a parameter acquisition unit, and a system calibration unit.
[0053] Optionally, such as Figure 7As shown, the test adjustment unit includes an interface module, a transition module, and an adjustment module. The interface module includes an extension interface for the transmission cooler's oil circuit. The interface module connects to the transition module. The transition module provides a mounting platform for the sensors and simultaneously splits the transmission cooler's oil circuit interface in the interface module into two parts via a three-way valve, connecting the transmission cooler (i.e., the radiator) and a heat dissipation device respectively. The heat dissipation device is a test heat dissipation device used to replace the transmission's own cooler; compared to the transmission cooler, this heat dissipation device has a larger external surface area and stronger heat exchange capacity with the environment. The adjustment module includes a three-way valve. When the three-way valve is in position P1, it connects the interface module to the transmission cooler; when the three-way valve is in position P2, it connects the interface module to the aforementioned heat dissipation device. Furthermore, it adjusts the oil circuit matching in the transition module, thereby adjusting the test target of the parameter acquisition unit.
[0054] Optionally, such as Figure 8 As shown, the parameter acquisition unit includes: sensors, a data acquisition module, and a data processing module. The sensors include an outlet pressure sensor (sensor 2) and an inlet pressure sensor (not shown in the figure) at the transmission cooling oil circuit interface 1, and an outlet flow sensor (sensor 3) at the transmission cooling oil circuit interface 1. The data acquisition module is a signal amplifier used to amplify and process the signals acquired by the sensors before transmitting them to the data processing module. The data processing module records the pressure and flow parameters of the transmission cooling oil circuit interface as T1 when the adjustment module in the test adjustment unit connects the oil circuit to the actual vehicle cooler. When the adjustment module in the test adjustment unit connects the oil circuit to the heat dissipation device, it records the pressure and flow parameters of the transmission cooling oil circuit interface as T2.
[0055] Optionally, such as Figure 9 As shown, the system calibration unit includes an automatic adjustment module, an execution module, and a drive module.
[0056] The system calibration unit includes an automatic adjustment module, an execution module, and a drive module. The automatic adjustment module receives parameters from the parameter acquisition unit and controls the execution and drive modules to ensure that parameter T2 in the data acquisition unit matches parameter T1. The execution module includes a programmable DC power supply and a solenoid valve; it is used to adjust the pressure value acquired by the sensor at the transition module in the test adjustment unit. Figure 4 This is a schematic flowchart of a control method for a transmission cooling system according to one optional embodiment of the present invention. Figure 4 As shown, the method includes the following steps:
[0057] Step S1: When the test adjustment unit is in P1, the parameter acquisition unit measures parameter group T1.
[0058] In other words, by adjusting the three-way valve in the test adjustment unit, the parameter group T1 is obtained by connecting it to the vehicle cooler.
[0059] Step S2: When the test adjustment unit is in P2, the parameter acquisition unit measures parameter group T2;
[0060] In other words, by adjusting the three-way valve in the test adjustment unit to connect the heat dissipation device, parameter group T2 is measured.
[0061] Step S3: The system calibration unit adjusts the execution module and the drive module to make T2 consistent with T1;
[0062] In the system calibration unit, the drive module uses an electric pump, the execution module uses a programmable power supply and solenoid valves, and the automatic adjustment module uses a combination of computer and PLC to control the drive and execution modules. The system calibration unit adjusts the execution and drive modules to make T2 and T1 converge.
[0063] Step S4: The system calibration unit locks the current system parameters;
[0064] The system parameters include, but are not limited to, the speed of the electric pump and the opening degree of the pressure control valve. The technical solution of this embodiment provides an automatic calibration method for a transmission cooling system, enabling the transmission to achieve rapid cooling without affecting its various operating conditions, improving testing efficiency, and meeting the testing and calibration requirements of transmissions under low-temperature conditions.
[0065] Figure 5 This is a structural block diagram of a control device for a transmission cooling structure according to one embodiment of the present invention, such as... Figure 5 As shown, the device includes: a first acquisition unit 61 for acquiring first operating condition parameters, wherein the first operating condition parameters are obtained by measuring the first operating state of the first branch, and the first operating condition parameters include at least: the flow rate of coolant flowing through the cooler and the pressure of coolant flowing through the cooler; a second acquisition unit 62 for acquiring second operating condition parameters, wherein the second operating condition parameters are obtained by measuring the second operating state of the second branch, and the second operating condition parameters include at least: the flow rate of coolant flowing through the heat dissipation device and the pressure of coolant flowing through the heat dissipation device, wherein the heat dissipation device is structurally different from the cooler and is used to rapidly cool the transmission; a generation unit 63 for generating control commands based on the first and second operating condition parameters; and a control unit 64 for adjusting the second operating condition parameters based on the control commands so that the adjusted second operating condition parameters and the first operating condition parameters meet preset conditions.
[0066] The aforementioned device enables the setting of a first branch with a cooler and a second branch with a heat dissipation device. By collecting the first operating parameters of the first branch and the second operating parameters of the second branch, and adjusting the second operating parameters based on the first and second operating parameters, the second branch with the heat dissipation device can rapidly cool the transmission using the heat dissipation device. Furthermore, it ensures that the transmission's operating environment when using the heat dissipation device remains consistent with its operating environment without an external heat dissipation device, thus maintaining the transmission's operating environment. This allows the transmission to achieve rapid cooling without affecting its various operating conditions, improving testing efficiency and solving the technical problem of slow cooling speed in existing transmission cooling systems.
