[0028] The shutdown control command is transmitted to the monitoring and control device and the transmission controller to control the hybrid transmission test system and the hybrid transmission under test to stop working.

[0029] The present invention also proposes a hybrid transmission test system comprising:

[0050] Improving energy efficiency, transforming energy utilization systems, and achieving electrification, new energy, and clean transportation have become the trends and directions for the development of urban public and private transportation. As a result, the market for hybrid vehicles is growing rapidly. Hybrid vehicle transmissions, as one of the core components of a car, have a complex structure. To ensure transmission quality, their performance must be tested on a test bench before leaving the factory. Currently, due to the highly specialized nature of test bench operation, operators require professional training. Furthermore, during testing, if the test bench or hybrid vehicle transmission malfunctions, the lag in manual operation can lead to damage to the test bench or transmission, resulting in economic losses.

[0051] In view of this, the present invention proposes a monitoring and control method based on a hybrid transmission test system, which can simultaneously monitor the hybrid transmission and the hybrid transmission test system. When abnormalities occur in the hybrid transmission or the hybrid transmission test system, feedback actions are used to alert the test personnel, facilitating timely handling and preventing significant damage to the hybrid transmission or the hybrid transmission test system. Figure 1The image shows an embodiment of the monitoring and control method based on a hybrid transmission test system provided by the present invention.

[0052] The present invention also proposes a hybrid transmission test system 100. The input motor 11 is used to simulate a car engine to provide driving force for the hybrid transmission. The torque input to the hybrid transmission is measured by the first torque meter 12. The output motor 21 is used to simulate road load to realize driving road condition simulation. The output torque of the hybrid transmission is measured by the second torque meter 22. In this way, the hybrid transmission test system 100 completes the performance monitoring and testing of the hybrid transmission.

[0053] like Figure 1 The diagram shown is a flowchart illustrating a specific embodiment of a monitoring and control method based on a hybrid transmission test system according to the present invention.

[0054] Please see Figure 1 In this embodiment, the monitoring and control method based on the hybrid transmission test system includes the following steps:

[0055] Step S10: Obtain at least one test monitoring parameter;

[0056] Step S20: When the test monitoring parameters meet the preset conditions, generate control commands;

[0057] Step S30: Send the control command to the feedback device to control the feedback device to perform a feedback action.

[0058] Before testing the hybrid transmission 200, relevant monitoring parameters of the components to be monitored in the hybrid transmission 200 under test must be entered into the hybrid transmission test system 100. Specifically, during the testing of the hybrid transmission 200 under test, at least one test monitoring parameter of the hybrid transmission 200 and the hybrid transmission test system 100 needs to be acquired. When the test monitoring parameter meets preset conditions, a control command is generated and sent to the feedback device to control the feedback device to perform a feedback action. In this way, the hybrid transmission 200 and the hybrid transmission test system 100 can be monitored simultaneously. When any test monitoring parameter of the hybrid transmission 200 or the hybrid transmission test system 100 meets the corresponding preset conditions, a feedback action can be used to remind the test personnel, so as to handle the situation in a timely manner and avoid causing significant damage to the hybrid transmission 200 or the hybrid transmission test system 100.

[0059] Specifically, the test monitoring parameters include data from the hybrid transmission 200 under test and test system data. Thus, during the test, both the hybrid transmission 200 and the hybrid transmission test system 100 can be monitored simultaneously, allowing for feedback when any one of the test monitoring parameters of the hybrid transmission 200 or the hybrid transmission test system 100 meets the corresponding preset conditions.

[0060] Furthermore, the hybrid transmission under test 200 includes a transmission motor and an electric pump; the data of the hybrid transmission under test 200 includes at least one of the actual operating speed of the transmission motor, the actual operating temperature of the transmission motor, and the actual flow rate of the electric pump. Thus, during the test, feedback is provided when any one of the actual operating speed of the transmission motor, the actual operating temperature of the transmission motor, and the actual flow rate of the electric pump meets the corresponding preset conditions.

[0061] Specifically, the hybrid transmission test system 100 includes a power simulation device 1 and a load simulation device 2. The power simulation device 1 includes an input motor 11 and a first torque meter 12, and the load simulation device 2 includes an output motor 21 and a second torque meter 22. The test system data includes at least one of the actual operating speed of the input motor 11, the actual torque of the first torque meter 12, the actual operating speed of the output motor 21, and the actual torque of the second torque meter 22. Thus, during the test, feedback is provided when any one of the actual operating speed of the input motor 11, the actual torque of the first torque meter 12, the actual operating speed of the output motor 21, and the actual torque of the second torque meter 22 meets the corresponding preset conditions.

[0062] In this embodiment, the test monitoring parameters include the test system data and the data of the tested hybrid transmission 200; in step S20:

[0063] An alarm control command is generated when either the test system data or the data of the tested hybrid transmission 200 exceeds the corresponding preset condition.

[0064] Thus, during the test, if any data in the test system data or the test hybrid transmission 200 data exceeds the corresponding preset conditions, an alarm control command is generated. After the alarm control command is sent to the feedback device, the feedback device performs a feedback action to remind the test personnel to handle the abnormal situation and avoid causing serious damage to the hybrid transmission 200 and the hybrid transmission test system 100.

[0065] In this embodiment, the hybrid transmission test system 100 includes a power simulation device 1, which includes an input motor 11 and a first torque meter 12; the test monitoring parameters include the actual operating speed of the input motor 11 and the actual torque of the first torque meter 12. Further, in step S20:

[0066] An alarm control command is generated when the actual operating speed of the input motor 11 exceeds the first preset speed threshold of the input motor 11 and / or the actual torque of the first torque meter 12 exceeds the preset torque threshold of the first torque meter 12.

[0067] Thus, during the test, when the actual operating speed of the input motor 11 exceeds the first preset speed threshold of the input motor 11, an alarm control command is generated. After the alarm control command is sent to the corresponding feedback device, the feedback device performs a feedback action to remind the operator that the speed of the input motor 11 is abnormal. When the actual torque of the first torque meter 12 exceeds the preset torque threshold of the first torque meter 12, an alarm control command is generated. After the alarm control command is sent to the corresponding feedback device, the feedback device performs a feedback action to remind the operator that the torque data measured by the first torque meter 12 is abnormal. When the actual operating speed of the input motor 11 exceeds the first preset speed of the input motor 11, and the actual torque of the first torque meter 12 exceeds the preset torque threshold of the first torque meter 12, an alarm control command is generated. After the alarm control command is sent to the two corresponding feedback devices respectively, the two feedback devices perform a feedback action to remind the operator that the speed of the input motor 11 is abnormal and the torque data measured by the first torque meter 12 is abnormal. Specifically, for example, the preset speed range threshold of the input motor 11 is 0 to 16000 r / min. When the actual operating speed of the input motor 11 is 16000 r / min, an alarm control command is generated and sent to the feedback device to control the feedback device to perform a feedback action. Similarly, in the hybrid transmission 200 test, the preset conditions of other monitoring test parameters can be set according to the actual needs of each monitoring data, which will not be elaborated here.

[0068] In this embodiment, the hybrid transmission under test 200 includes a transmission motor and an electronic pump. The hybrid transmission test system 100 includes a power simulation device 1, a load simulation device 2, and a feedback device. The feedback device includes multiple alarms, which are correspondingly set with respect to the transmission motor, the electronic pump, the power simulation device 1, and the load simulation device 2. Specifically, step S30 includes:

[0069] The control command is sent to the corresponding alarm to control the alarm to flash.

[0070] Thus, during the test, when any one of the test monitoring parameters of the gearbox motor, the electronic pump, the power simulation device 1, and the load simulation device 2 meets the corresponding preset conditions, an alarm control command is generated. This alarm control command is then sent to the corresponding alarm to control the alarm to flash. It should be noted that the specific type of the feedback device is not limited; it can be an alarm, a monitoring and control device, or a gearbox controller.

[0071] like Figure 2 The diagram shown is a schematic of the monitoring and control process of the input motor 11 in a monitoring and control method based on a hybrid transmission test system 100 according to the present invention.

[0072] Please see Figure 2 In this embodiment, the hybrid transmission test system 100 includes a power simulation device 1 and a monitoring and control device. The power simulation device 1 includes an input motor 11, and the hybrid transmission under test 200 includes a hybrid gearbox and a gearbox controller. The test monitoring parameters include the actual operating speed of the input motor 11. More specifically, step S20 includes:

[0073] When the actual operating speed of the input motor 11 exceeds the second preset speed threshold of the input motor 11, a shutdown control command is generated;

[0074] The process after step S20 also includes:

[0075] The shutdown control command is transmitted to the monitoring and control device and the transmission controller to control the hybrid transmission test system 100 and the hybrid transmission under test 200 to stop working.

[0076] Thus, when the actual operating speed of the input motor 11 exceeds the second preset speed threshold of the input motor 11, a shutdown control command is generated. Furthermore, after the shutdown control command is sent to the monitoring and control device and the transmission controller, the hybrid transmission test system 100 and the hybrid transmission under test 200 are controlled to stop working, so as to avoid causing major damage to the hybrid transmission 200 and the hybrid transmission test system 100.

[0077] like Figure 3 and Figure 4 The image shows an embodiment of the hybrid transmission test system provided by the present invention.

[0078] like Figure 3As shown, the present invention also proposes a hybrid transmission test system 100 including a power simulation device 1, a load simulation device 2, a high-voltage battery simulator 3, a constant temperature cooler 4, and a monitoring and control device. The power simulation device 1 includes an input motor 11 and a first torque meter 12. The input shaft of the first torque meter 12 is connected to the output shaft of the input motor 11, and the output shaft of the first torque meter 12 is connected to the input shaft of the hybrid transmission. The input motor 11 is used to simulate a car engine. The load simulation device 2 includes an output motor 21 and a second torque meter 22. The input shaft of the second torque meter 22 is connected to the output shaft of the output motor 21, and the input shaft of the second torque meter 22 is connected to the output shaft of the hybrid transmission. The output motor 21 is used to simulate road loads. The high-voltage battery simulator 3 is used to simulate a battery pack to supply power to the hybrid transmission 200. The constant temperature cooler 4 is used to cool the hybrid transmission 200. The monitoring and control device (see reference) Figure 4 The monitoring and control device is electrically connected to the first torque meter 12, the second torque meter 22, the hybrid transmission 200 controller, and the transmission controller. The monitoring and control device includes a memory, a processor, and a monitoring and control program based on the hybrid transmission test system 100 stored in the memory and executable on the processor. The monitoring and control program based on the hybrid transmission test system 100 is configured to implement the steps of the monitoring and control method of the hybrid transmission test system 100 described above. Thus, the performance monitoring and testing of the hybrid transmission is completed through the hybrid transmission test system 100.

[0079] It should be noted that the processor 1001, such as a central processing unit (CPU), includes a communication bus 1002, a user interface 1003, a network interface 1004, and a memory 1005. The communication bus 1002 is used to enable communication between these components. The user interface 1003 may include a display screen or an input unit such as a keyboard; optionally, the user interface 1003 may also include a standard wired interface or a wireless interface. The network interface 1004 may optionally include a standard wired interface or a wireless interface (such as a Wi-Fi interface). The memory 1005 may be a high-speed random access memory (RAM) or a stable non-volatile memory (NVM), such as a disk drive. The memory 1005 may also optionally be a storage device independent of the aforementioned processor 1001.

[0080] Those skilled in the art will understand that Figure 3 The structure shown does not constitute a limitation on the monitoring and control device, and may include more or fewer components than shown, or combine certain components, or have different component arrangements.

[0081] Specifically, the hybrid transmission test system 100 further includes a first speed control box 5 and a second speed control box 6. The first speed control box 5 is located between the input motor 11 and the first torque meter 12, and is driven and connected to both the input motor 11 and the first torque meter 12, respectively, for adjusting the output speed of the input motor 11. The second speed control box 6 is located between the output motor 21 and the second torque meter 22, and is driven and connected to both the output motor 21 and the second torque meter 22, respectively, for adjusting the output speed of the output motor 21. Thus, by setting the first speed control box 5 and the second speed control box 6, the output and output speed of the hybrid transmission 2 test system 100 can be adjusted.
