[0060] The specific implementation methods of the present application are further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present application, but are not used to limit the scope of the present application.

[0061] Embodiment 1

[0062] Figure 1 is a flow chart of a hydraulic system testing method provided in an embodiment of the present application, such as Figure 1 As shown, the method includes:

[0063] S1, obtaining oil temperature signals and abnormal parameters for testing the hydraulic system;

[0064] S2, obtaining a temperature control strategy based on the oil temperature signal;

[0065] S3, controlling the temperature of the hydraulic system by controlling the environmental chamber according to the temperature control strategy to obtain temperature control data;

[0066] S4, obtain the fault strategy according to the abnormal parameters;

[0067] S5, troubleshooting is performed according to the fault strategy to obtain fault control data;

[0068] S6, testing the hydraulic system according to the temperature control data and the fault control data.

[0069] In the above implementation process, by integrating testing processes such as temperature control and troubleshooting into the test of the hydraulic system, the subsystems and components of the hydraulic system can be fully covered, which facilitates timely adjustment of each subsystem and component, provides a complete testing environment for the research of hydraulic control, improves the diversity and accuracy of the test, and provides more convenience for the test process.

[0070] The embodiments of the present application can solve the problem of high difficulty in testing the hydraulic system of a hybrid transmission. The test system of the present application is provided with a calibrable simulated load, which can accurately simulate the test environment of the hydraulic system placed in the transmission assembly, can comprehensively cover the subsystems and components, meet the conditions for measuring relevant parameters, and make timely adjustments to the subsystems and components.

[0071] The method of the embodiment of the present application can be applied to a hydraulic test system, such as Figure 2 As shown, the motor (or bench motor) replaces the engine as the power source of the mechanical pump. The mechanical pump rotates to absorb oil from the oil tank. The lubricating oil passes through the filter at the head end of the pipeline, passes through the mechanical pump in turn, and then passes through different solenoid valves inside the valve body and then pumped out, and returns to the oil tank through the terminal simulated load system. There are multiple sensors arranged in the test system, including speed sensors and torque sensors at the motor end, temperature sensors, liquid pressure sensors and flow meters in the pipeline, etc., which can realize real-time monitoring of test parameters and feedback to the industrial computer, and collect data of multiple parameters for test analysis.

[0072] Based on the structural schematic diagram of the test system, the entire test system is composed of multiple components. For the hybrid transmission mechanical pump and the hydraulic control module integrated with the valve body and its cooperating components, such as the oil cooler and filter, a multi-modular design is adopted, and each component can be flexibly adjusted and matched to achieve the purpose of test diversity. The motor simulates the engine to deliver power to the mechanical pump. The end of the test system is equipped with a calibrable simulated load system. The simulated load system consists of multiple groups of solenoid valves, which can send current signals to control the solenoid valves according to the throttle hole size calculated by simulation, thereby simulating the flow resistance of the lubricating oil in the transmission assembly oil circuit. The above description of the test system shows that it truly and accurately simulates the test environment of the hydraulic control module on the transmission assembly in many aspects.

[0073] S2 includes:

[0074] Obtain the oil temperature threshold value pre-set according to the test conditions;

[0075] Compare the oil temperature signal with the oil temperature threshold to obtain a comparison result;

[0076] The temperature control strategy is obtained based on the comparison results.

[0077] In the above implementation process, the oil temperature can be accurately controlled, so that the comparison of the oil temperature signal is not easily disturbed by the external environment, the comparison result can be made more accurate, and the availability and practicality of the temperature control strategy can be improved.

[0078] Furthermore, the step of obtaining a temperature control strategy according to the comparison result includes:

[0079] If the comparison result shows that the oil temperature signal is higher than the upper threshold value of the oil temperature threshold value, a cooling strategy is obtained, and the cooling strategy is determined to be a temperature control strategy;

[0080] If the comparison result is that the oil temperature signal is lower than the lower threshold value of the oil temperature threshold value, a temperature increase strategy is obtained, and the temperature increase strategy is determined to be a temperature control strategy.

[0081] In the above implementation process, the temperature environment of the hydraulic system is determined according to the upper and lower thresholds in the oil temperature threshold, and the temperature can be adjusted in time, which improves the flexibility of oil temperature control and the hydraulic system's ability to control temperature.

[0082] The application can monitor the oil temperature in real time. When the oil temperature does not meet the working temperature, the industrial control machine will issue a command to automatically adjust the temperature to meet the test conditions. The heating method of the hydraulic system includes heating by mechanical pump stirring oil and heating by heat exchange in the environmental chamber. The cooling method includes heat exchange of low-temperature coolant and cooling in the environmental chamber. The system heating rate and temperature control accuracy can be improved, thereby improving the measurement accuracy of the test system.

[0083] The present application sets up multiple temperature sensors to monitor the oil temperature in real time. When the oil temperature exceeds the lower threshold, the oil temperature alarm system is triggered, and the heating strategy of the environmental chamber is automatically stopped and the motor stops driving the mechanical pump. The same applies when the temperature is lower than the lower threshold.

[0084] Furthermore, S3 includes:

[0085] If the temperature control strategy is a cooling strategy, a cooling signal instruction is obtained;

[0086] According to the temperature reduction signal instruction, the motor is controlled to stop rotating, so that the temperature of the environmental chamber starts to decrease, until the temperature of the environmental chamber reaches the target temperature, and the temperature control data is obtained;

[0087] If the temperature control strategy is a temperature increase strategy, a temperature increase signal instruction is obtained;

[0088] According to the temperature rise signal instruction, the oil cooling system is controlled to stop running, so that the environmental chamber starts to heat up and obtains the temperature rise measurement data;

[0089] The temperature control data is obtained based on the temperature rise measurement data.

[0090] In the above implementation process, the temperature of the environmental chamber is controlled in different ways according to different temperature control strategies, so that the temperature of the environmental chamber can be adjusted in real time according to the temperature control strategy to ensure the rationality of the temperature of the environmental chamber.

[0091] In the actual test process, the operator can set the upper and lower thresholds (oil temperature thresholds) of the oil temperature according to the test conditions before the test starts. In the test process, the data acquisition system monitors and collects the oil temperature in real time and feeds back the corresponding signal instructions to the industrial computer. When the oil temperature exceeds the upper threshold, the cooling strategy is triggered. The industrial computer sends a cooling signal to instruct the bench motor to stop rotating, the environmental chamber starts to cool down, and the oil cooling system starts the low-temperature coolant to flow quickly through the pipeline to exchange heat with the high-temperature lubricating oil. In summary, the cooling purpose is achieved until the temperature meets the working conditions. The cooling strategy stops the test and continues.

[0092] When the oil temperature is lower than the lower threshold or a higher oil temperature is required at the beginning of the test, the temperature increase strategy is triggered. At this time, the oil cooling system stops running, the environmental chamber temperature increases, and the test bench motor starts running to stir the oil and increase the temperature.

[0093] Furthermore, the step of obtaining temperature control data according to the temperature rise measurement data includes:

[0094] Obtaining mapping relationship data between target temperature and motor speed according to temperature rise measurement data;

[0095] Import the mapping relationship data into the industrial computer to obtain the target speed of the motor;

[0096] The temperature rise is controlled according to the target speed to obtain temperature control data.

[0097] In the above implementation process, the mapping relationship data between the target temperature and the motor speed is obtained according to the temperature rise measurement data, so that the target speed of the motor can be obtained quickly and accurately, thereby performing temperature rise control, which can improve the accuracy of temperature rise control.

[0098] This application uses a large amount of temperature rise measurement data based on the temperature rise strategy to determine the mapping relationship between the target oil temperature and the test bench motor speed, and import it into the industrial computer. Before the test, the operator can determine the target speed of the test bench motor according to different oil temperatures to achieve automatic control of the temperature rise.

[0099] Furthermore, after the step of troubleshooting according to the fault strategy and obtaining the fault control data, the following steps are also included:

[0100] Perform pressure adjustment test on the hydraulic system according to abnormal parameters.

[0101] In the above implementation process, pressure regulation testing of the hydraulic system can realize real-time monitoring of pipeline oil pressure and other key parameters, and propose corresponding fault solving strategies to reduce the risk of failure caused by oil pressure.

[0102] In terms of troubleshooting and solving faults, this application can monitor the abnormal conditions of various parameters in real time and feedback them to the industrial computer, making corresponding judgments and solving fault strategies. A pressure regulating valve is set in the system pipeline. Once the pipeline pressure is abnormal, the industrial computer issues a command to adjust the pressure regulating valve to realize automatic control of the oil pressure to meet the working conditions.

[0103] Furthermore, the step of performing a pressure adjustment test on the hydraulic system according to the abnormal parameters includes:

[0104] Obtain pipeline pressure data from abnormal parameters;

[0105] Obtain pressure regulation signal instructions according to pipeline pressure data;

[0106] Perform pressure regulation test on the hydraulic system according to the pressure regulation signal command.

[0107] In the above implementation process, a pressure regulation signal instruction is obtained according to the pipeline pressure data, and then a pressure regulation test is performed, so that the oil pressure can be regulated in real time and accurately, thereby improving the flexibility of oil pressure regulation.

[0108] In terms of pipeline pressure monitoring, this application sets up multiple pressure sensors and flow sensors to monitor pipeline pressure and flow in real time. When the pipeline pressure exceeds the set upper and lower thresholds, the pressure relief regulating valve in the pipeline will make relevant adjustments to restore the pipeline pressure to the test threshold range. The system monitors multiple influencing factors in real time and proposes relevant strategies for various faults to reduce the risk of failure.

[0109] In the embodiment of the present application, the volumetric efficiency and mechanical efficiency of the mechanical pump and the overall efficiency of the hydraulic system can be obtained by calculation.
