[0023] In some situations, cooling, heating, and water circulation in new energy vehicles all rely on multi-way water valves. By controlling the valve body of a single multi-way water valve, switching between different water flow channels can be achieved.

[0024] The current HIL bench test method for five-way water valves uses the enable signal and valve body angle position control signal on the analog bus as inputs, monitors the XCP signal in the main control module, and outputs the water valve status signal fed back to the bus. This test method can only test the basic functions of the five-way water valve, cannot cover all operating conditions, is not suitable for precise control testing, and has a large signal delay.

[0025] Based on the above, this application proposes a HIL bench test method, controller, medium, and program product for automotive water valves, aiming to achieve accurate testing of the control process of multi-way water valves under different operating conditions.

[0026] The various embodiments of the HIL bench test method for automotive water valves of this application will be further described below with reference to the accompanying drawings.

[0027] For multi-way water valves, such as five-way water valves, the valve body is moved to different positions by a motor to change the flow direction of the coolant and thus achieve different system cycle switching. The PWM signal is fed back by a Hall sensor to calculate the current position of the valve body.

[0028] like Figure 1 As shown, Figure 1 This is a graph showing the relationship between the motor rotation angle and the number of pulses provided in one embodiment of this application; the correspondence between the valve body operating angle and the Hall sensor pulses is as follows: the relationship between motor rotation and Hall sensor feedback is that the motor rotates once and feeds back two pulses.

[0029] In addition, such as Figure 2 As shown, Figure 2 This is a diagram showing the relationship between the number of pulses and various angle intervals provided in one embodiment of this application. Specifically, the actual limit of the five-way water valve is from c° to d°. When the water valve rotates forward, it hits the limit at c°. At this time, the valve body hits the limit and does not move, but the motor continues to rotate, and the number of pulses continues to increase. This process generates the starting overshoot pulse N1. Similarly, the water valve hits the limit at d° and generates the ending overshoot pulse N2. Therefore, the limit interval pulse Ne = the actual received total pulse Na - the starting overshoot pulse N1 - the ending overshoot pulse N2; that is, Ne = Na - (N1 + N2).

[0030] Based on the above control principles, and taking the multi-way water valve as the control target, a test method for HIL bench testing is proposed: like Figure 3 As shown, Figure 3is a flowchart of a HIL bench test method of an automobile water valve provided by an embodiment of the present application. The HIL bench test method of the automobile water valve includes but is not limited to step S310, step S320 and step S330.

[0031] Step S310, generating an active test model for testing the multi-way water valve, adjusting model parameters of the active test model; Step S320, executing a water valve control test sequence based on the active test model to simulate water valve passages under multiple working conditions; Step S330, obtaining HIL output parameters of the active test model after the water valve control test sequence is executed, and determining a performance level of the multi-way water valve according to the HIL output parameters.

[0032] Specifically, first, an active test model suitable for function verification of the multi-way water valve is constructed. The model can be flexibly configured by the upper computer test software. Engineers can accurately adjust core model parameters such as PWM frequency, duty cycle, closed-loop control target current range, and current error threshold according to the motor characteristics, control requirements, and test targets of the multi-way water valve. At the same time, the real water valve hardware and the virtual simulation environment, such as the new energy automobile thermal management system virtual model containing the battery cooling loop and the warm air water valve loop, are bound to ensure that the model can realize accurate driving and working condition simulation of the water valve. Then, based on the configured active test model, a water valve control test sequence covering multiple actual running scenarios is built in the upper computer software, including battery water valve passage switching, warm air water valve passage conduction, self-learning calibration under normal working conditions, and extreme working condition and fault injection scenarios. By modifying the model flag parameter, simulating the bus enable signal and the valve body angle control signal as input, the test sequence is triggered to automatically execute, and the key running data of the water valve under each working condition is monitored in real time, such as motor current, valve core rotation total pulse number, pulse change rate, and passage flow. Finally, after the water valve control test sequence is executed, the system automatically collects the HIL full-quantity parameters output by the active test model, such as current time sequence data, pulse characteristic data, and working condition response delay in each test stage. Through the upper computer software, these parameters are comprehensively analyzed, and the preset qualified standard is compared to determine whether the function logic, control accuracy, extreme working condition adaptability, and fault tolerance capability of the multi-way water valve meet the standards, and finally determine the overall performance level.

[0033] In an embodiment, the active test model is provided with a function parameter adjustment area. Regarding the adjustment of the model parameters of the active test model in step S310, the model parameters of the active test model are adjusted according to the target adjustment parameters input in the function parameter adjustment area.

[0034] As shown in Figure 4 , the function parameter adjustment area is provided with a plurality of function parameter adjustment interfaces, and each function parameter adjustment interface is configured to adjust a corresponding function parameter of the active test model. Figure 4is a flowchart of adjusting model parameters of the active test model provided by an embodiment of the present application. The flowchart includes but is not limited to step S410 or step S420.

[0035] Step S410, in the case that the functional parameter adjustment region includes a PWM adjustment region, in response to the target PWM frequency and / or target PWM duty cycle set in the PWM adjustment region, so that the target PWM frequency and / or target PWM duty cycle of the active test model is within the target control range; Step S420, in the case that the functional parameter adjustment region includes a current adjustment region, in response to the target current range set in the current adjustment region, so that the actual current of the active test model is kept within the target control range by automatically increasing or decreasing the command current.

[0036] Specifically, when the functional parameter adjustment region of the host computer HIL test software contains a PWM adjustment module, the test personnel first manually input the target PWM frequency and / or target PWM duty cycle in the visual operation interface of the adjustment region according to the motor rated parameters, driving requirements and test scene requirements of the multi-way water valve to be tested; the system responds to the setting operation in real time, synchronizes the input target parameters to the PWM drive control unit of the active test model, and at the same time, through the parameter verification logic built-in the model, combines the preset target control range to verify the compliance of the set parameters, if the parameters are within the allowed range, the parameters take effect directly, if the parameters exceed the range, the parameters are prompted and automatically corrected to the nearest compliant value, finally ensuring that the frequency and / or duty cycle of the PWM drive signal output by the active test model is within the preset target control range, providing a stable and reliable signal basis for the accurate driving and subsequent working condition test of the multi-way water valve.

[0037] In addition, when the functional parameter adjustment region of the host computer HIL test software contains a current adjustment module, the test personnel first set the target current range in the current adjustment region according to the motor rated current, load demand under different working conditions and control accuracy requirements of the multi-way water valve to be tested; the system responds to the setting operation in real time, synchronizes the target current range parameters to the closed-loop current control unit of the active test model, and the model starts the current adaptive adjustment logic immediately: during the execution process of the water valve control test sequence, the actual working current of the multi-way water valve motor is collected in real time through the current sensor, and is compared with the set target current range in real time, if the actual current is lower than the lower limit of the range, the active test model automatically increases the command current output, adjusts the PWM duty cycle to increase the drive voltage to increase the motor current; if the actual current is higher than the upper limit of the range, the model automatically reduces the command current, reduces the PWM duty cycle to limit the current rise; the whole adjustment process is dynamically cycled until the actual current is stably maintained within the preset target control range, ensuring that the motor operates under safe load, and at the same time, ensuring the water valve control accuracy and working condition adaptability.

[0038] As Figure 5 shown, Figure 5 is a flowchart provided by an embodiment of the present application for building a test sequence and simulating an input signal. The flowchart includes but is not limited to step S510 and step S520.

[0039] Step S510, building a water valve control test sequence through the host computer test sequence software, and changing the corresponding parameters of the flag bit in the active test model; Step S520, simulating the enable signals and valve body control signals of the multi-way water valve in different working conditions on the bus as input signals.

[0040] Specifically, the test personnel builds a water valve control test sequence suitable for the function verification of the multi-way water valve through the editing interface of the host computer test sequence software: the sequence construction can be completed by dragging the working condition modules, such as the battery water valve passage, the heater water valve passage, self-learning calibration, motor stall fault, etc., setting the execution order and duration of each working condition; then the active test model configured is called in the sequence editing panel, the flag bit parameters of the corresponding working conditions in the model are adjusted through the parameter modification function, for example, the "battery water valve mode" flag bit is set to 0x01, the "heater water valve mode" flag bit is set to 0x02, and the "motor stall fault" flag bit is set to 0x03, to realize the accurate triggering of different test scenarios; at the same time, the software simulates the signal interaction logic of the real communication bus of the new energy vehicle through the bus simulation function, generates the corresponding enable signals and valve body control signals according to the requirements of each working condition, and real-time issues these simulated signals as input signals to the bus interface of the multi-way water valve, to drive the water valve to perform corresponding actions under each preset working condition, laying a foundation for subsequent performance parameter collection and verification.

[0041] In an embodiment, during the execution of the water valve control test sequence, the method further includes monitoring the working parameters of the multi-way water valve in multiple functional states, wherein the functional states include a battery thermal management functional state, a heater thermal management functional state, a self-learning state, or a fault injection state, and the working parameters include total pulse number change, pulse number change rate, or current parameter.

[0042] Specifically, during the execution of the built water valve control test sequence based on the host computer HIL test system, the system synchronously starts the multi-dimensional real-time monitoring mechanism, and the whole-process data acquisition is performed for the running conditions of the multi-way water valve in different functional states: when the test sequence triggers the battery thermal management functional state, the total pulse number change, pulse number change rate and real-time current parameters of the motor during the rotation of the valve core in the process of switching the water valve to the battery cooling / heat preservation passage are monitored; when the sequence switches to the warm air thermal management functional state, the above-mentioned core working parameters when the water valve is turned on the warm air circuit are monitored, and the action accuracy and current stability in the cabin heating / defrosting scene are verified; after the self-learning state is triggered, the calibration change of the total pulse number, the dynamic fluctuation of the pulse change rate and the abnormal characteristics of the current parameters in the process of the water valve finding the mechanical limit are tracked; when the fault injection state is executed, whether the total pulse number is stagnant, whether the pulse change rate is suddenly reduced to 0, and whether the current parameters have abnormal performances such as sudden rise / sudden drop are continuously recorded, and through the comprehensive monitoring of the total pulse number change, the pulse number change rate and the current parameters in each functional state, complete data support is provided for the subsequent performance evaluation of the water valve.

[0043] As shown in Figure 6 , Figure 6 is Figure 3 a sub-step flow chart of one embodiment of step S330. Regarding step S330 described above, it includes but is not limited to step S610 and step S620.

[0044] Step S610, collect the HIL output current parameters of the active test model in each test stage of the water valve control test sequence; Step S620, for each test stage, compare the HIL output current parameters with the preset current parameters to obtain the performance level of the multi-way water valve.

[0045] Specifically, during the whole process of the water valve control test sequence executed by the host computer HIL test system, the system collects the HIL current parameters output by the active test model in real time at a preset high sampling rate, covering the full timing current data of each test phase such as the battery thermal management function starting phase, the warm air thermal management function action phase, the self-learning calibration phase, the fault injection phase, etc., including the starting peak current, the action phase average current, the stable phase holding current, the fluctuation amplitude, the rise / fall time, etc. Key indicators; for each test phase, the host computer software automatically calls the preset current parameters, compares and analyzes the collected HIL output current parameters with the preset current parameters of the corresponding phase: if the starting peak current output by the HIL in a certain phase is within the preset threshold, the deviation of the action phase average current from the preset value does not exceed the allowed range, and the current fluctuation amplitude meets the requirements, it is determined that the performance of this phase meets the standard; if the peak current exceeds the threshold, the fluctuation amplitude is too large or the response time is too long, etc. Marked as performance anomaly; by comprehensively summarizing the comparison results of the current parameters of all test phases, the control precision, the running stability, the extreme condition adaptability and the fault tolerance ability of the multi-way water valve under various working conditions are finally determined, and whether its overall performance level meets the design specification is clear.

[0046] As Figure 7 shown, Figure 7 is Figure 6 a sub-step flowchart of one embodiment of step S620. Regarding step S620 described above, it includes but is not limited to step S710 and step S720.

[0047] Step S710, acquire all dimensions of HIL output current parameters; Step S720, for each test phase, compare all dimensions of HIL output current parameters with the corresponding preset current parameters respectively, and obtain the performance level of the multi-way water valve.

[0048] Specifically, in the whole process of the water valve control test sequence executed by the host computer HIL test system, the system collects all dimensional HIL output current parameters output by the active test model in real time at a high sampling rate, covering peak current, valley current, average current, current fluctuation amplitude, current rise time, current fall time, duty cycle-current correlation data, temperature-current linkage data, and other multi-dimensional characteristics; for each test stage such as battery thermal management function, warm air thermal management function, self-learning, and fault injection, the host computer software automatically calls the corresponding preset current parameters of each dimension, and accurately compares each item of collected dimensional HIL output current parameters with the preset current parameters of the corresponding stage: if the HIL output current parameters of all dimensions in a certain stage meet the preset standard, it is determined that the performance of this stage meets the standard; if any dimensional parameter exceeds the preset range, it is marked as a performance anomaly of the corresponding dimension; by comprehensively analyzing the comparison results of the dimensional parameters of all test stages, the control accuracy, running stability, extreme environment adaptability, and fault tolerance capability of the multi-way water valve under various working conditions are comprehensively evaluated, and finally it is determined whether the overall performance level meets the design specification.

[0049] Based on the various embodiments of the HIL bench test method of the automobile water valve of the above embodiments, the overall embodiments of the HIL bench test method of the automobile water valve of the present application are proposed as follows.

[0050] As shown in Figure 8 , the Figure 8 is the overall flowchart of the HIL bench test method of the automobile water valve provided by an embodiment of the present application.

[0051] In an embodiment, the present embodiment realizes the verification of the function logic of the five-way water valve by controlling the PWM frequency, collecting the current size, monitoring the pulse number change and change rate, and the specific steps are as follows: Step S810, adjust the active test model parameters: The active test model of the present embodiment based on the preset PWM duty cycle size can realize the adjustment of the voltage size and the motor rotation rate by changing the parameters.

[0052] In addition, it can realize the control of the PWM frequency size in the target control range by adjusting the active model parameters, the target current output by the closed-loop adjustment controller, and the automatic addition and subtraction of the command current by the controller.

[0053] Step S820, execute the water valve control test sequence, and simulate the water valve passage under different working conditions: The host computer test sequence software realizes automatic sequence building, model parameter modification, and evaluation index building.

[0054] In the automatic test sequence built in the host computer test sequence software, the parameters corresponding to the flag bits in the calling model are changed, and the enable and valve body control signals of the five-way water valve under different working conditions on the bus are simulated as inputs.

[0055] Monitor key signals such as total pulse count change, pulse count change rate, and current of the water valve under various states including battery-operated water valve, heating air water valve, self-learning, and fault injection.

[0056] Step S830: Collect and verify whether the output current of HIL meets the requirements. The current output by HIL is collected, and the current at each stage of the active test is compared and judged.

[0057] The larger the duty cycle of the active control model, the higher the voltage, and the relatively larger the current value collected.

[0058] Different motors have their own suitable frequencies. If the frequency is too low, the valve body movement will be unstable. If the frequency is too high, the motor will not be able to respond. Therefore, the control current of each stage needs to be compared and judged based on the changes in all currents.
