Description

Technical Field

[0001] The present invention relates to the field of gearbox testing, and in particular to a simulation method and system for the jamming of an AMT gearbox solenoid valve. Background Art

[0002] The solenoid valve is a key component in the AMT transmission. For example, in the AMT system, the clutch actuator solenoid valve is responsible for controlling the engagement and disengagement of the clutch, thereby realizing the transmission of power; the shift actuator solenoid valve can control the changes in the internal oil circuit of the transmission according to the vehicle's driving conditions and the driver's operation, thereby realizing the switching between different gears.

[0003] The ECU (electronic control unit) of the AMT system will calculate the optimal control strategy based on various sensor data (such as vehicle speed, throttle position, engine speed, etc.), and send instructions to the solenoid valve corresponding to a certain execution structure to adjust the state of the execution device corresponding to a certain execution structure or complete a certain operation. In other words, whether the execution structure can complete the corresponding operation depends on whether the corresponding solenoid valve can work normally.

[0004] When the solenoid valve is stuck during driving, it will affect the operation of the corresponding actuator. In this case, the gearbox may not be able to complete normal operations (such as shifting gears). In extreme cases, the engine may stall or fail to start, resulting in a reduced driving experience. In severe cases, the gearbox and engine may be damaged, affecting driving safety.

[0005] In order to further confirm and verify the performance of the AMT transmission when a certain actuator solenoid valve is stuck and the impact on the driving process, it is necessary to simulate and reproduce the sticking of a certain actuator solenoid valve as a necessary functional test of the transmission.

[0006] The common detection methods at present include realizing physical jamming by disassembling and assembling the actuator of the actual vehicle; installing temporary jumpers, relays or switches on the circuit that controls the clutch solenoid valve in the laboratory or test bench to simulate jamming; special tools or equipment can be used to simulate various faults in the electronic control system, including the jammed state of the solenoid valve. These fault simulators can apply a jammed solenoid valve fault condition to the circuit without actually destroying the circuit and mechanical structure. However, these methods have problems such as long test cycle, high cost, lack of safety guarantee, and single test conditions, which are not conducive to improving the efficiency and safety of solenoid valve jam fault simulation and reducing simulation costs.

[0007] In view of this problem, the present invention provides a method and system for simulating the sticking of an AMT transmission solenoid valve to solve the above problem. Summary of the invention

[0034] In order to clearly illustrate the technical features of the present solution, the present invention is described in detail below through specific implementation methods and in conjunction with the accompanying drawings. The disclosure below provides many different embodiments or examples for realizing different structures of the present invention. In order to simplify the disclosure of the present invention, the components and settings of specific examples are described below.

This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed. It should be noted that the components illustrated in the accompanying drawings are not necessarily drawn to scale. The present invention omits the description of known components and processing techniques and processes to avoid unnecessary limitations on the present invention.

[0035] Embodiment 1

[0036] like Figure 1 As shown, the present invention provides a method for simulating the stuck state of an AMT transmission solenoid valve, comprising:

[0037] S1, establishing an AMT gearbox HIL test bench, wherein the AMT gearbox HIL test bench includes an AMT gearbox, an execution structure module, an AMT gearbox electronic control unit, and a solenoid valve module; the solenoid valve module corresponds to the execution structure module and is used to drive the execution structure to perform corresponding operations according to the control instructions of the AMT gearbox electronic control unit;

[0038] S2, establish a communication connection between the host computer and the AMT transmission electronic control unit in the AMT transmission HIL test bench;

[0039] S3, based on the host computer, configure the parameters of the AMT transmission electronic control unit in the AMT transmission HIL test bench, so that the AMT transmission electronic control unit generates control instructions to control the solenoid valve module to drive the execution structure module to perform corresponding operations under the parameter configuration of the host computer, so as to realize the simulation of the solenoid valve module jam fault.

[0040] Among them, in step S1, on the one hand, the execution structure module includes a first execution structure, the first execution structure is a clutch actuator, and the solenoid valve module includes a first type of solenoid valve sub-module, the first type of solenoid valve sub-module corresponds to the first execution structure, and is used to drive the first execution structure to perform a first type of operation under a first type of control instruction of the AMT transmission electronic control unit; the first type of solenoid valve sub-module includes a number of first type solenoid valves corresponding to the clutch execution structure.

[0041] Specifically, the first type of solenoid valve submodule includes a fast-opening solenoid valve for controlling fast opening of the clutch, a slow-opening solenoid valve for controlling slow opening of the clutch, a fast-closing solenoid valve for controlling fast closing of the clutch, and a slow-closing solenoid valve for controlling slow closing of the clutch (each of which is a first type of solenoid valve); the simulation of solenoid valve sticking includes the simulation of normally open faults and normally touching faults of the fast-opening solenoid valve, the simulation of normally open faults and normally touching faults of the slow-opening solenoid valve, the simulation of normally open faults and normally touching faults of the fast-closing solenoid valve, and the simulation of normally open faults and normally touching faults of the slow-closing solenoid valve.

[0042] It should be noted that, in the present embodiment, slow opening, slow closing, fast opening and fast closing describe objects such as slow disconnection of the clutch, slow closing (or engagement) of the clutch, fast disconnection of the clutch and fast closing of the clutch. Slow and fast are relative to each other. The specific classification standard can be customized according to actual conditions (for example, slow when it is below a certain speed threshold and fast when it is not lower than the speed threshold). The existing speed definitions of slow disconnection and closing or fast disconnection and closing of the clutch can also be adopted. The present embodiment does not make any limitation here.

[0043] For example, the ECU (electronic control unit) of the AMT system will calculate the optimal shifting strategy based on various sensor data (such as vehicle speed, throttle position, engine speed, etc.) and driving conditions, and send instructions to the solenoid valve to adjust the clutch state. When the vehicle starts, the ECU will calculate the appropriate clutch engagement level based on the current situation, and use the solenoid valve to drive the clutch actuator to gradually and slowly fit the gearbox, so that the engine power is smoothly transmitted to the transmission system. When parking, the ECU will gradually and smoothly separate the gearbox until the power transmission is completely disconnected. When shifting gears is required, the ECU will first instruct the solenoid valve to drive the clutch actuator to disconnect the clutch and cut off the power connection between the engine and the gearbox; then control the gearbox to select the appropriate gear; finally, the solenoid valve drives the actuator to re-engage the clutch to resume power transmission. In other words, whether the clutch separation and engagement can be completed depends on whether the solenoid valve can work normally.

[0044] When the solenoid valve is stuck during driving, it will affect the operation of the corresponding clutch and gear mechanism. In this case, the gearbox may not be able to complete the normal clutch separation and engagement, which may cause frustration during shifting, inability to complete shifting, interruption of power transmission, increased clutch wear and other problems. In extreme cases, the engine may stall or fail to start, resulting in a reduced driving experience. In severe cases, it may damage the gearbox and engine, affecting driving safety.

[0045] In order to further confirm and verify the performance of the AMT transmission when the solenoid valve of the clutch actuator is stuck and its impact on driving, it is necessary to simulate and reproduce the sticking of the clutch actuator solenoid valve as a necessary functional test of the transmission.

[0046] This embodiment uses professional simulation tools (such as MATLAB / Simulink) to build a virtual model of the gearbox, which can reproduce the behavior of the gearbox system on the computer, including the performance under normal working conditions and various fault scenarios. In this way, the system response under different conditions can be safely tested without actually damaging the physical components. For more complex scenarios, the HIL test method is adopted, and the real controller can be combined with the simulation tool using a specially designed test bench to verify the system performance in a controlled environment. This method allows engineers to make an accurate assessment of the system behavior under specific conditions (such as solenoid valve jamming), set the corresponding parameters in the simulation environment so that the model reflects the solenoid valve jamming situation, change the input and output conditions according to the predetermined program, and observe how the system reacts.

[0047] On the other hand, the execution structure module also includes a second execution structure, which is a shift execution structure. The solenoid valve module also includes a second type of solenoid valve submodule; the second type of solenoid valve submodule corresponds to the second execution structure and is used to drive the second execution structure to perform a second type of operation under the second type of control instruction of the AMT transmission electronic control unit; the second type of solenoid valve submodule includes a plurality of second type solenoid valves corresponding to the shift execution mechanism.

[0048] The second type of solenoid valve submodule includes a first gear selection solenoid valve corresponding to the gear selection structure in the gear shift execution structure, a second gear selection solenoid valve corresponding to the gear selection structure in the gear shift execution structure, a first gear shift solenoid valve corresponding to the gear shift structure in the gear shift execution structure, a second gear shift solenoid valve corresponding to the gear shift structure in the gear shift execution structure, a first plug-in gear solenoid valve corresponding to the plug-in gear structure in the gear shift execution structure, a second plug-in gear solenoid valve corresponding to the plug-in gear structure in the gear shift execution structure, a first range gear solenoid valve corresponding to the range gear structure in the gear shift execution structure, and a second range gear solenoid valve corresponding to the range gear structure in the gear shift execution structure. Solenoid valves (each of which is a second type solenoid valve); the simulation of solenoid valve sticking includes the normally open fault and normally touched fault simulation of the first gear selection solenoid valve, the normally open fault and normally touched fault simulation of the second gear selection solenoid valve, the normally open fault and normally touched fault simulation of the first gear shift solenoid valve, the normally open fault and normally touched fault simulation of the second gear shift solenoid valve, the normally open fault and normally touched fault simulation of the first plug-in and split gear solenoid valve, the normally open fault and normally touched fault simulation of the second plug-in and split gear solenoid valve, the normally open fault and normally touched fault simulation of the first range gear solenoid valve, and the normally open fault and normally touched fault simulation of the second range gear solenoid valve.

[0049] For example, the AMT transmission receives various signals from vehicle sensors through the electronic control unit (ECU), such as vehicle speed, engine speed, throttle position, etc. Based on this information, the ECU determines when and how to shift gears, and sends instructions to the shift actuator, such as the solenoid valve or pneumatic valve, to control the flow of hydraulic oil, thereby controlling the engagement and disengagement of components such as the clutch and brake. The solenoid valve or pneumatic valve will change the oil pressure line accordingly, so that the various gear sets in the transmission mesh or disengage in a predetermined order to complete the shift process. In other words, whether the shift can be completed depends on whether the solenoid valve can work properly.

[0050] During driving, if the solenoid valve is stuck, that is, the solenoid valve cannot be opened or closed correctly, it will affect the operation of the corresponding clutch or gear mechanism. In this case, the gearbox may not be able to complete normal gear shifting, or even be locked in a certain gear, resulting in a reduced driving experience, poor fuel economy, and in severe cases, damage to the gearbox.

[0051] In order to further confirm and verify the performance of the AMT transmission when the shift solenoid valve is stuck and its impact on driving, it is necessary to simulate and reproduce the solenoid valve sticking as a necessary functional test of the transmission. However, the current common detection methods are not ideal in terms of time, cost, safety, etc.

[0052] The present embodiment uses professional simulation tools (such as MATLAB / Simulink) to build a virtual model, which can reproduce the behavior of the gearbox system on the computer, including the performance under normal working conditions and various fault scenarios. In this way, the system response under different conditions can be safely tested without actually damaging the physical components. For more complex scenarios, the HIL test method is adopted, and the real controller can be combined with the simulation tool using a specially designed test bench to verify the system performance in a controlled environment. This method allows engineers to make an accurate assessment of the system behavior under specific conditions (such as solenoid valve jamming), set the corresponding parameters in the simulation environment so that the model reflects the solenoid valve jamming situation, change the input and output conditions according to the predetermined program, and observe how the system reacts.

[0053] In step S2, the software program and the HIL test bench required for the test are started in the PC computer (host computer).

[0054] Open the corresponding program of the gearbox type to be tested in the PC host software (different test programs can be preset in advance according to the gearbox type to test and simulate different types of gearboxes).

[0055] Flash the corresponding transmission program into the transmission electronic control unit (ECU).

[0056] Perform relevant operations of the simulated vehicle on the PC host interface.

[0057] The various parameters of the clutch actuator solenoid valve of the AMT transmission bench model are modified and configured in the simulation software model and the PC host computer respectively.

[0058] In step S3, if Figure 2-Figure 5 As shown, when the execution structure is a clutch action execution structure, the AMT transmission clutch action execution mechanism is divided into four solenoid valves: fast opening, slow opening, fast closing, and slow closing to control the engagement and separation of the clutch.

[0059] Based on the host computer, the AMT gearbox electronic control unit in the AMT gearbox HIL test bench is parameterized, and the AMT gearbox electronic control unit generates control instructions to control the solenoid valve module to drive the execution structure module to perform corresponding operations under the parameter configuration of the host computer, so as to simulate the solenoid valve module jam fault. Specifically:

[0060] The host computer configures the configuration parameters corresponding to each first-type solenoid valve in sequence through the AMT transmission electronic control unit in the AMT transmission HIL test bench. The AMT transmission electronic control unit generates control instructions for each first-type solenoid valve of the normally open fault and / or normally touched fault according to the configuration parameters corresponding to each first-type solenoid valve of the host computer, controls each first-type solenoid valve of the normally open fault and / or normally touched fault, and outputs the operation results of each first-type solenoid valve driving the first execution structure to engage or disconnect the clutch when it has a normally open fault and / or a normally touched fault, so as to realize the simulation of the solenoid valve module sticking fault.

[0061] Specifically, the host computer configures the slow-closing solenoid valve configuration parameters through the AMT transmission electronic control unit in the AMT transmission HIL test bench.

[0063] The host computer configures the configuration parameters of the fast-closing solenoid valve through the AMT transmission electronic control unit in the AMT transmission HIL test bench.

[0064] The host computer configures the quick-opening solenoid valve configuration parameters through the AMT transmission electronic control unit in the AMT transmission HIL test bench. The AMT transmission electronic control unit generates control instructions for the quick-opening solenoid valve normally-open fault and / or normally-touch fault according to the quick-opening solenoid valve configuration parameters of the host computer, controls the quick-opening solenoid valve to normally-open fault and / or normally-touch fault, and outputs the operation results of the quick-opening solenoid valve driving the first execution structure to execute the quick-disconnection clutch when the quick-opening solenoid valve has a normally-open fault and / or a normally-touch fault, so as to realize the simulation of the solenoid valve module sticking fault.

[0065] Among them, when the first type of solenoid valve is a slow closing solenoid valve, the slow closing solenoid valve configuration parameters corresponding to the control instruction of the normally open fault of the slow closing solenoid valve are specifically:

[0066] The first configuration parameter Ctrl_VCCS_PHY is set to 0 (under normal circumstances, the value of the parameter Ctrl_VCCS_PHY that controls the clutch slow closing solenoid valve is 0 when there is no action, and the value is 1 when it is action), the second configuration parameter Ctrl_VCCS_Switch is set to 1 to enable, and the third configuration parameter Ctrl_VCCS_Input is set to 0.

[0072] The fourth configuration parameter Ctrl_VCOS_PHY is set to 0, the fifth configuration parameter Ctrl_VCOS_Switch is set to 1 to enable, and the sixth configuration parameter Ctrl_VCOS_Input is set to 1.

[0073] Among them, when the first type of solenoid valve is a fast-closing solenoid valve, the fast-closing solenoid valve configuration parameters corresponding to the control instruction of the fast-closing solenoid valve normally open fault are specifically:

[0074] The seventh configuration parameter Ctrl_VCCF_PHY is set to 0 (under normal circumstances, the value of the parameter Ctrl_VCCF_PHY that controls the clutch quick-closing solenoid valve is 0 when it is not in action, and 1 when it is in action), the eighth configuration parameter Ctrl_VCCF_Switch is set to 1 to enable, and the ninth configuration parameter Ctrl_VCCF_Input is set to 0;

[0081] The first configuration parameter Ctrl_VCCS_PHY, the fourth configuration parameter Ctrl_VCOS_PHY, the seventh configuration parameter Ctrl_VCCF_PHY, and the tenth configuration parameter Ctrl_VCOF_PHY are set to 0 and are all one of the first working configuration parameters Ctrl_VCxx_PHY; the second configuration parameter Ctrl_VCCS_Switch, the fifth configuration parameter Ctrl_VCOS_Switch, the eighth configuration parameter Ctrl_VCCF_Switch, and the eleventh configuration parameter Ctrl_VCOF_Switch are all one of the first enabling configuration parameters Ctrl_VCxx_Switch, and the third configuration parameter Ctrl_VCCS_Input, the sixth configuration parameter Ctrl_VCOS_Input, the ninth configuration parameter Ctrl_VCCF_Input, and the twelfth configuration parameter Ctrl_VCOF_Input are all one of the first input configuration parameters Ctrl_VCxx_Input.

[0082] The above operations can set the corresponding parameters according to the test requirements to complete the simulation of the normally open fault and the normally touching fault of the AMT transmission clutch actuator solenoid valve stuck. This technical solution can not only simulate the normally open fault of the AMT transmission clutch actuator solenoid valve stuck, but also simulate the normally touching fault of the clutch actuator solenoid valve. It can complete the simulation of the clutch actuator solenoid valve stuck under different working conditions such as in situ and during driving. It solves the problems of the traditional methods such as physical disconnection of the actual vehicle actuator solenoid valve, installation of relays, switches and special fault simulators, such as long test cycle, high cost, lack of safety guarantee, single test conditions, difficulty in reproducing working conditions, greater environmental impact, and narrow test coverage. At the same time, it also solves the problem that the original bench technical solution cannot simulate the clutch actuator solenoid valve stuck fault.

[0083] In step S3, if Figure 6-Figure 9 As shown, when the execution structure is a gear shifting action execution structure, the AMT gearbox gear shifting action execution mechanism is divided into gear selection (Gate), gear shift (Gear), split gear (Split), and range gear (Range), and the four gears are respectively controlled by two solenoid valves, namely valve 1 and valve 2.

[0084] Based on the host computer, the AMT gearbox electronic control unit in the AMT gearbox HIL test bench is parameterized, and the AMT gearbox electronic control unit generates control instructions to control the solenoid valve module to drive the execution structure module to perform corresponding operations under the parameter configuration of the host computer, so as to simulate the solenoid valve module jam fault. Specifically:

[0085] The host computer configures the configuration parameters corresponding to each second type solenoid valve in sequence through the AMT transmission electronic control unit in the AMT transmission HIL test bench. The AMT transmission electronic control unit generates control instructions for each second type solenoid valve of the normally open fault and / or normally touched fault according to the configuration parameters corresponding to each second type solenoid valve of the host computer, controls each second type solenoid valve of the normally open fault and / or normally touched fault, and outputs the operation results of driving the second execution structure to execute gear shifting for each second type solenoid valve in the case of normally open fault and / or normally touched fault, so as to realize the simulation of the solenoid valve module stuck fault.

[0086] Specifically, when the second type of solenoid valve is a first gear selection solenoid valve, the first gear selection solenoid valve configuration parameters are output respectively to drive the second execution structure to execute the gear selection operation result when a normally open fault and / or a normally touched fault occurs, so as to realize the simulation of the solenoid valve module stuck fault.
