[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0019] Refer to Figures 1-9 , a test system for a hybrid power system of a hybrid vehicle, including a monitoring platform 1, and the monitoring platform 1 includes a test vehicle 11, a condition module 12, a test platform module 13, a monitoring module 14, and a maintenance module 15: The test vehicle 11 includes an electric power system module 111 and a hydraulic power system module 112. Additionally, the electric power system module 111 and the hydraulic power system module 112, as common power energies, can also use compressed natural gas, propane, ethanol fuel, etc. as driving energies; The condition module 12 is used to simulate vehicle driving conditions and perform data analysis. Specifically, CANoe is used, which specifically supports various vehicle network protocols such as CAN, LIN, FlexRay, and Ethernet, and is mainly used for the development, analysis, simulation, testing, diagnosis, and startup of automotive manufacturers and electronic controller suppliers. In automotive testing, it can be used to establish simulation models, evaluate the functions of ECUs, analyze system functions, and perform integrated testing of bus systems and ECUs, and can also perform automatic testing and generate test reports.

[0020] The condition module 12 includes a consumption factor section 121, an external factor section 122, a structure factor section 123, and a driving factor section 124 that affect vehicle driving; The consumption factor section 121 includes oil quality 1211 and time 1212. If the quality of the oil quality 1211 is poor, it will affect the engine and vehicle performance. The external factor section 122 includes temperature signal transmission 1221, humidity signal transmission 1222, road signal transmission 1223, wind force signal transmission 1224, and resistance signal transmission 1225. The temperature signal transmission 1221 can adjust the external temperature through a temperature regulator and analyze the impact on the test vehicle 11 at different temperatures. The humidity signal transmission 1222 can adjust the external humidity through a humidity controller and analyze the impact on the test vehicle 11 at different humidities; The road signal transmission 1223 simulates the road conditions, making the road present various different states such as flat, bumpy, uphill, and downhill, and then tests the test vehicle 11 under different states. The wind force signal transmission 1224 can adjust the external wind force through the mutual cooperation of a large fan and a wind force measuring instrument and analyze the impact on the test vehicle 11 at different wind forces.

[0021] During the testing process, the condition module 12 is achieved by continuously innovating and replacing the control variable method: Node simulation: It can simulate the behaviors of each node on the bus, including ECUs, sensors, actuators, etc. That is, when developing an automotive air conditioning control system, CANoe is used to simulate nodes such as the air conditioning control unit, temperature sensor, and fan motor to verify the operation logic and control strategy of the system under different working conditions.

[0022] Scenario simulation: Create various complex vehicle operation scenarios to simulate the communication situation of the vehicle under different driving conditions. That is, simulate the information interaction between each ECU when the vehicle is in working conditions such as accelerating, decelerating, and turning to test the reliability and real-time performance of the automotive electronic system during actual driving.

[0023] It also has a learning function. It obtains data and information during a large number of tests and establishes an environment model core suitable for itself, supports writing automated test cases, defining test steps, expected results, etc. For example, write test cases for the automotive airbag system, including triggering conditions, sensor signal simulation, and expectations for the response of the airbag control unit, etc., to achieve automated testing of the system function. It can also perform self-testing under unmanned conditions, automatically execute test cases, and generate detailed test reports. The report contains test results, error information, data statistics, etc., which is convenient for developers to quickly understand the test situation of the system, locate problems, and make improvements.

[0024] During use, by integrating the MATLAB Simulink system and the Parasoft C / C++ test system, the former helps to achieve system modeling, simulation, and analysis. Vehicle dynamics models, control system models, etc. can be created. In combination with other tools, software-in-the-loop (SIL) and model-in-the-loop (MIL) test environments can be constructed for algorithm development, function verification, and performance evaluation. For example, in the development of autonomous driving systems, simulation tests can be carried out on perception algorithms, decision-making algorithms, etc.; the latter can integrate multiple test technologies into one tool and well support automotive standards such as AUTOSAR, MISRA, and ISO 26262. It can automate test technologies such as static analysis, unit testing, and code coverage, helping the development team ensure that the software meets the requirements of safety-critical markets, while supporting requirement traceability and facilitating viewing the relationships between requirements and source code, test cases, and results.

[0025] Furthermore, the maximum speed of gasoline vehicles is 180 km - 220 km / h, and their acceleration performance is weak during high-speed driving. Their endurance is suitable for long-distance travel but the fuel consumption is high. The maximum speed of electric vehicles is 250 km - 290 km / h, and their endurance will be greatly shortened during high-speed driving while the cost is low. On long and rough roads, the power consumption speed of electric vehicles is greater than the fuel consumption speed of gasoline vehicles, that is, gasoline vehicles are superior to electric vehicles. If it is a short and rough road, then electric vehicles are superior to gasoline vehicles.

[0026] Therefore, the following three groups of comparative experiments are carried out: The structural factor section 123 includes power signal transmission 1231, power structure transmission 1232, traffic facility transmission 1233, and vehicle-mounted signal transmission 1234. The driving factor section 124 includes traffic signal transmission 1241, brake signal transmission 1242, throttle signal transmission 1243, and driving signal transmission 1244. The differences between the drive system in the power signal transmission 1231 and the power components such as vehicle models, transformers, tires, gearboxes, and engines in the power structure transmission 1232 can reflect the impact on the test vehicle 11. The traffic facility transmission 1233 includes traffic signs, markings, and speed control facilities on the road. The vehicle-mounted signal transmission 1234 refers to the impact of the load weight of the test vehicle 11 on itself, and the impact on the test vehicle 11 caused by the driver's frequent braking, stepping on the throttle, and driving habits; The test platform module 13 is used to sort out the vehicle information collected by the condition module 12, and the test platform module 13 analyzes and predicts the information during the vehicle test process; Further explanation: The test bench section 131 is composed of a hydraulic cylinder, a jack, and a support platform, and the test vehicle 11 is lifted and lowered by the movement of the support platform. The display bench section 132 is composed of a control console and a display screen. The display screen can display the data of the test vehicle 11 during the test process, and can also display, monitor, and analyze the test results of the test vehicle 11; The structure section 133 can simulate the situations encountered by the test vehicle 11 during driving under different factors, and the simulation structures include speed bumps, uphill, downhill, rain, temperature, wind, etc. The installation section 134 refers to installing the simulation structures in the structure section 133 on the support platform to facilitate the testing of the test vehicle 11, and can quickly reflect the driving results of the test vehicle 11 under different factors. The shooting section 135 is composed of a camera and a transmission line, and the test vehicle 11 is monitored in real time during the test process through the camera; The test platform module 13 includes a test bench section 131, a display bench section 132, a structure section 133, an installation section 134, a shooting section 135, and a modeling section 136. The modeling section 136 includes a hierarchical modeling 1361 and a combined modeling 1362. The test bench section 131 is used to support the lifting of the vehicle, the display bench section 132 is used to display the monitoring results of vehicle detection, the structure section 133 is used to simulate vehicle driving conditions, and the installation section 134 is used to fix the structure section 133. Supplementary explanation: The results obtained by the test vehicle 11 under the simulation of the condition module 12 are transmitted into the modeling section 136, and hierarchical modeling 1361 is carried out according to each period of time. When the test vehicle 11 finishes the test, comparison is made according to the results detected in each period of time through combined modeling 1362; Further explanation: Hierarchical modeling 1361 establishes basic information on the driving speed, driving distance, energy consumption, structural response, etc. of the test vehicle 11 within each small time under the influence of the condition module 12. When the energy consumption of the test vehicle 11 reaches the bottom, the changes in vehicle speed, driving distance, and structural loss can be displayed on the display bench section 132, and hierarchical modeling 1361 can also establish new basic information according to the changes of the test vehicle 11 within each period of time; At the same time, combined modeling 1362 can quickly reflect the driving range and the best operation mode of the test vehicle 11 under different road conditions and different energies according to different driving energies; Hierarchical modeling 1361 consists of a numbering function block, a timing function block, a metering function block, and a line graph function block: Among them, the numbering function block is used to mark the test vehicle 11 with a number for the convenience of conducting experiments of the same group type, and the timing function block is used to time the test process; The metering function block is used to mark the mileage accumulation, energy loss, and structural loss of the test vehicle 11, and the line graph function block is used to present the abnormal data of the test vehicle 11 to facilitate the elimination or marking of useful information; It should be noted that the modeling section 136 preferably uses the GT - Suite system: which is used to establish detailed models of components such as the engine, motor, battery, and transmission system of a hybrid vehicle, conduct coupled simulations of multiple physical fields such as thermal management, fluid mechanics, and dynamics, and proceed in an orderly manner: (1) Determine the modeling objectives and scope and collect data; (2) Select a modeling method; (3) Establish a model; (4) Model integration and optimization; (5) Model verification and application.

[0027] An example code for discrete - event simulation of hybrid vehicle energy management using Python and SimPy libraries is implemented for operations such as those shown in the appendix of the specification Figure 8 of the running operation.

[0028] The monitoring module 14 is used to monitor the vehicle conditions on the test platform module 13 in real - time; The monitoring module 14 includes an energy supply monitoring section 141, a cruising range monitoring section 142, a parts monitoring section 143, a speed monitoring section 144, a position monitoring section 145, an energy monitoring section 146, and an alarm monitoring section 147. The energy supply monitoring section 141 is used to provide energy supply, the cruising range monitoring section 142 is used to monitor the cruising range of the vehicle, the parts monitoring section 143 is used to monitor the vehicle structure conditions, the speed monitoring section 144 is used to monitor the vehicle speed, the energy monitoring section 146 is used to monitor the usage degree of the vehicle, and the alarm monitoring section 147 is used to give sound warnings and light warnings to the vehicle during the monitoring process. During the monitoring process, the test vehicle 11 can monitor the power energy in real - time through the cruising range monitoring section 142 and replenish the power energy in a timely manner. The parts monitoring section 143 can view the running conditions of the parts in real - time, thereby ensuring the stability of the test vehicle 11 during the detection process. The moving speed of the test vehicle 11 can be monitored through the speed monitoring section 144, and the tester can be alerted by the warning sound and warning light emitted by the alarm monitoring section 147.

[0029] By setting the attribute monitoring function module, various data during vehicle driving are recorded, such as vehicle speed, following - distance, torque output of the engine and motor, battery SOC, etc., and these data are used to identify driving conditions. The K - means++ clustering algorithm can be used for condition classification, a vehicle following model based on the minimum safety distance is established, and a model predictive controller is designed.

[0030] Furthermore, by using Simcenter3D, Simcenter Amesim software, and the LMS Test.Lab test platform, the NVH vibration and noise characteristics of the hybrid powertrain are analyzed and predicted. Based on Amesim, a 1D model is established, sensitivity analysis is carried out, and sensitive parameters are identified, such as system clearances, the hysteresis torque of the torsional damper, system speed fluctuations, flywheel inertia, motor rotor inertia, etc., and verification and optimization are carried out in combination with experimental means.

[0031] The maintenance module 15 conducts maintenance management on the test vehicle 11, the condition module 12, the test platform module 13, and the monitoring module 14. The maintenance module 15 includes a daily maintenance section 151, a spot-check maintenance section 152, and a structural supplement section 153. The daily maintenance section 151 can maintain the detection elements. The spot-check maintenance section 152 conducts maintenance on the detection elements regularly. The structural supplement section 153 replenishes the necessary detection elements in a timely manner.

[0032] The functional principle of the present invention can be described through the following operating modes: When two systems on the test vehicle 11 are tested, the two systems include a power system module 111 and an oil power system module 112; Drive the test vehicle 11 onto the test platform module 13. The test bench can adjust the height of the test vehicle 11 and install the structural plate 133 through the installation plate 134, so that the structural plate 133 can simulate the external road conditions through wind, rain, temperature, etc. The display platform plate 132 can display the monitoring results of the test vehicle 11 for the inspector to observe in real time; Affect the vehicle driving conditions through the condition module 12. The quality of the oil will affect the driving of the test vehicle 11; In the external factor section 122, the external temperature is simulated through the temperature signal transmission 1221. Simulate the test vehicle 11 driving and operating under the separate drive of electricity or oil for a specified duration. The external weather water content is simulated through the humidity signal transmission 1222 to test the influence of the test vehicle 11 on its own speed under different water contents. The flat road, bumpy road, uphill road, and downhill road are respectively simulated through the road signal transmission 1223. The external wind speed is simulated through the wind signal transmission 1224, so that the electric vehicle and the oil vehicle drive under the influence of wind. The resistance signal transmission 1225 simulates the driving of the electric vehicle and the oil vehicle under a certain resistance; At the same time, traffic facilities such as traffic flow and traffic lights encountered during the operation of the test vehicle 11 are simulated according to the traffic facility transmission 1233, and the driving habits of the driver are simulated through the driving signal transmission 1244; The results obtained from the test of the test vehicle 11 under the simulation of the external factor section 122 will be transmitted into the modeling section 136. The modeling section 136 can reflect the changes generated by electric vehicles and fuel vehicles within each hour into the hierarchical modeling 1361. The hierarchical modeling 1361 can establish basic information on the driving speed, driving distance, energy consumption, structural response, etc. of the test vehicle 11 within each hour, and establish different basic information according to the energy consumption of the test vehicle 11, enabling the observer to quickly view the changes of the test vehicle 11 and further judge the driving range and optimal operation mode of the test vehicle 11 under different energy conditions; The power supply monitoring section 141 in the monitoring module 14 can perform power supply operations to keep the monitoring equipment running normally. The endurance monitoring section 142 can monitor the consumption of electric vehicles and fuel vehicles. The part monitoring section 143 can monitor the stability of the parts of electric vehicles and fuel vehicles during driving. The energy monitoring section 146 can monitor the operation of drive components such as the gearbox and engine in electric vehicles and fuel vehicles; When the energy of the electric vehicle and the fuel vehicle is exhausted, the information is merged through the combined modeling 1362, marked according to the basic information of each test result of the test vehicle 11, and the test data is input into the combined modeling 1362, so that the test results are reflected in the form of a line graph. The mutually merged data can identify the mileage accumulation, energy loss, and structural loss of the test vehicle 11, and mark the abnormal data generated by the test vehicle 11 during the test process. The tester can obtain the optimal operation rule according to the test results.

[0033] In summary, through the above tests on hybrid vehicles and improvements based on the result analysis, by adjusting parameters, the generator end load torque is adjusted to a preload of 2.5 Nm to achieve significant improvement, and a further improvement is achieved with a preload of 5 Nm; a combination of solutions such as reducing the spline fit clearance of the system, selecting the idle point, optimizing the housing structure, optimizing the shafting support design, and optimizing the strategy is adopted. By increasing the torsional stiffness of the system, the frequency corresponding to the booming noise is shifted to a higher frequency, reducing the resonance peak value of the booming noise and improving the subjective feeling of the booming noise.

[0034] The above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
