[0030] For ease of understanding, some concepts related to embodiments of the present invention are illustrated below for reference.

[0031] New Energy Vehicles (NEVs) refer to automobiles that use unconventional vehicle fuels as their power source (or use conventional vehicle fuels with new onboard power systems), integrating advanced technologies in vehicle power control and drive systems to form vehicles with advanced technical principles, new technologies, and new structures. NEVs include various types such as pure electric vehicles, plug-in hybrid electric vehicles, and fuel cell vehicles, and are characterized by low carbon emissions, environmental friendliness, and energy conservation.

[0032] Cooling System: In new energy vehicles, the cooling system is a device used to regulate the temperature of the vehicle's powertrain (including but not limited to the motor, battery, and electronic components) to ensure the stable operation of these components. A typical cooling system includes a water pump, radiator, coolant, various valves and sensors, and an electronic controller to control the flow path and speed of the coolant. The cooling system works by circulating coolant to remove heat and dissipate it into the external environment, thereby maintaining the powertrain within a suitable operating temperature range.

[0033] Pump power refers to the energy output provided by the electric motor or drive unit of a water pump during operation. Pump power is related to the flow rate and pressure of the coolant and is an important indicator of pump efficiency. In this application, changes in pump power are used to reflect changes in flow resistance within the cooling system, thereby determining whether a blockage exists.

[0034] Thermal Management: In new energy vehicles, thermal management refers to a systematic and comprehensive set of technologies used to monitor and control the temperature of various parts of the vehicle, especially the temperature management of key power components (such as drive motors and battery packs), to ensure that these components operate at optimal temperatures, extend their service life, and improve performance and safety. Thermal management technology encompasses multiple aspects such as cooling, heating, insulation, and temperature monitoring, and is an important component of the development of new energy vehicle technology. In this application, thermal management primarily focuses on the cooling system, ensuring that it is not affected by blockages, thereby maintaining good heat exchange performance.

[0043] This embodiment provides a method for determining the degree of blockage in a vehicle cooling system operating with electronic devices. Figure 1 This is a flowchart of a method for determining the degree of blockage in a vehicle cooling system according to one embodiment of the present invention, such as... Figure 1 As shown, the process includes the following steps:

[0044] Step S10: Obtain the vehicle power status;

[0045] In this embodiment of the invention, the vehicle power status is used to indicate the working status of the vehicle's electrical system, mainly including the vehicle's power-on status and the vehicle's power-off status, which are not limited here.

[0046] Obtaining vehicle power status can be understood as collecting information about the current operating mode of the vehicle's electrical system.

[0047] As can be seen, by acquiring the vehicle's power status, this invention ensures that the detection method is carried out under accurate and reliable conditions, avoiding misjudgments caused by unstable power supply or vehicle malfunction.

[0048] Step S12: Determine the vehicle water pump voltage, vehicle water pump speed, and vehicle system coolant temperature based on the vehicle power status.

[0049] In this embodiment of the invention, the vehicle water pump voltage refers to the voltage value that the water pump motor or drive device withstands during operation. In new energy vehicles, the water pump is generally electrically driven, and the vehicle water pump voltage value directly affects the water pump's working efficiency and power output.

[0050] Vehicle water pump speed refers to the number of revolutions per minute (rpm) of the water pump motor. The water pump speed directly affects the circulation speed and flow rate of the coolant within the system. In this invention, controlling the water pump to a specific or maximum speed is to assess the system's flow resistance under certain conditions, thereby determining whether a blockage exists.

[0051] Vehicle system coolant temperature refers to the temperature of the coolant (such as water, antifreeze, etc.) flowing through the cooling system. Coolant temperature not only reflects the operating condition of the cooling system but can also affect its viscosity, thus impacting the water pump's operating efficiency.

[0052] Determining the vehicle water pump voltage, water pump speed, and coolant temperature based on the vehicle's power status can be understood as determining whether the vehicle's power supply is in an on or off state, and then using that current state to determine the water pump voltage, water pump speed, and coolant temperature.

[0053] As can be seen, based on different vehicle power states and by determining the vehicle water pump voltage, vehicle water pump speed, and vehicle system coolant temperature, this invention can more accurately identify whether there is a blockage inside the cooling system under different vehicle power states.

[0054] Step S14: Analyze the vehicle water pump voltage, vehicle water pump speed, and vehicle system coolant temperature based on the relationship mapping table to determine the current degree of blockage in the vehicle cooling system. The relationship mapping table is used to represent the mapping relationship between the degree of blockage in the vehicle cooling system and the vehicle water pump power at different vehicle water pump speeds. The relationship mapping table is established based on water pump operating data, which reflects the operating status of the vehicle water pump.

[0055] In this embodiment of the invention, the relational mapping table is established by collecting and organizing the working data of the vehicle water pump under different operating conditions, using statistical methods, machine learning algorithms or other mathematical models, and is used to quickly and accurately determine the blockage status of the cooling system based on the water pump speed and water pump power.

[0056] Water pump operating data includes various performance indicators of the water pump under different operating conditions. Specifically, water pump operating data includes at least the following: vehicle water pump voltage, vehicle water pump speed, vehicle system coolant temperature, and vehicle water pump power.

[0057] Analyzing the vehicle's water pump voltage, water pump speed, and coolant temperature using a relational mapping table to determine the current degree of blockage in the vehicle's cooling system can be understood as follows: first, determine the vehicle's water pump voltage, water pump speed, and coolant temperature; then, analyze these parameters using a relational mapping table to determine the current degree of blockage in the vehicle's cooling system.

[0058] As can be seen, based on the relationship mapping table and the current water pump operating parameters, the degree of blockage in the cooling system can be quickly and accurately determined, thereby improving the efficiency and accuracy of cooling system blockage detection.

[0059] Based on the above steps, the vehicle's power status is first obtained. Then, based on the vehicle's power status, the vehicle's water pump voltage, water pump speed, and coolant temperature are determined. Finally, the vehicle's water pump voltage, water pump speed, and coolant temperature are analyzed based on a relationship mapping table to determine the current degree of blockage in the vehicle's cooling system. The relationship mapping table represents the mapping relationship between the degree of blockage in the vehicle's cooling system and the vehicle's water pump power at different water pump speeds. The relationship mapping table is established based on water pump operating data, which reflects the operating status of the vehicle's water pump. This achieves the goal of accurately judging the blockage status of the cooling system, thereby realizing the technical effect of effectively monitoring the blockage status of the cooling system and ensuring the safe operation of the vehicle. This solves the technical problem of inaccurate identification of the blockage status of the vehicle's cooling system in related technologies.

[0060] Optionally, in step S12, the vehicle water pump voltage, vehicle water pump speed, and vehicle system coolant temperature are determined based on the vehicle power status, including the following execution steps:

[0061] Step S121: In response to the vehicle power status indicating that the vehicle is powered on, determine whether the vehicle water pump is in normal operation based on the vehicle control logic.

[0062] Step S122: In response to the vehicle water pump being in normal operation, read the vehicle water pump voltage, vehicle water pump speed, and vehicle system coolant temperature after the target time period.

[0063] In this embodiment of the invention, vehicle control logic refers to a set of rules and algorithms used by the vehicle's Electronic Control Unit (ECU) or any related control system to monitor and control various electrical systems of the vehicle based on the vehicle's operating status and environmental conditions. In this invention, the vehicle control logic is primarily responsible for determining whether the vehicle's water pump can operate normally, and for controlling the water pump during the detection process.

[0064] The target time period is designed to ensure that the coolant temperature fed back by the temperature sensor accurately represents the actual temperature within the system. The water pump needs to run at normal speed for a period of time to allow for uniform coolant circulation and eliminate initial temperature inconsistencies in the system. The specific length of the target time period depends on vehicle characteristics, cooling system design, and test data, but it typically needs to be long enough to ensure the cooling system reaches a steady state. For example, in an embodiment of this invention, the target time period can be set to 1 minute, and this is not a limitation.

[0065] In response to the vehicle's power status indicating that the vehicle is powered on, determining whether the vehicle's water pump is operating normally based on the vehicle's control logic can be understood as follows: when the vehicle's power status indicates that the vehicle is powered on (i.e., the vehicle's electrical system has started working), the vehicle's electronic control unit or related control system will check whether the vehicle's water pump can operate normally as expected, according to the preset vehicle control logic. This step ensures that the water pump has not malfunctioned or is abnormal before subsequent testing, and can stably provide the necessary power to the cooling system.

[0066] In response to the vehicle water pump being in normal operating condition, reading the vehicle water pump voltage, vehicle water pump speed, and vehicle system coolant temperature after a target time period can be understood as follows: after confirming that the vehicle water pump can operate normally, the detection system will set a target time period, during which the water pump will continue to work so that the coolant can circulate in the system and reach a temperature equilibrium state, and then obtain the vehicle water pump voltage, vehicle water pump speed, and vehicle system coolant temperature.

[0067] As can be seen, when the vehicle is powered on, the working status of the vehicle water pump is judged based on the vehicle control logic, and the working data of the vehicle water pump is obtained after the target time period. This ensures that the method for determining the degree of blockage of the vehicle cooling system of the present invention can be carried out under optimal conditions, thereby improving the accuracy and effectiveness of the detection.

[0068] Optionally, in step S12, the vehicle water pump voltage, vehicle water pump speed, and vehicle system coolant temperature are determined based on the vehicle power status, including the following execution steps:

[0069] Step S123: In response to the vehicle power status indicating that the vehicle is in a powered-off state, activate the blockage detection process of the cooling system based on the target diagnostic equipment;

[0070] Step S124: With the blockage detection process in an active state, control the vehicle water pump to run at the test speed to determine whether the vehicle water pump is operating normally.

[0071] Step S125: In response to the vehicle water pump being in normal operation, the vehicle water pump voltage and vehicle system coolant temperature are acquired, and the vehicle water pump is controlled to run to the upper speed limit and the vehicle water pump speed is acquired, wherein the test speed is less than the upper speed limit.

[0072] In this embodiment of the invention, the target diagnostic device refers to a dedicated device used to activate and execute the cooling system blockage detection process. The target diagnostic device can be a professional automotive diagnostic tool, such as a diagnostic instrument, or a testing device integrated at the end of an automotive manufacturing plant's production line. The target diagnostic device can communicate with the vehicle's electronic control unit (ECU) and send specific commands or instructions to initiate a predefined detection process. When the vehicle is powered off, the target diagnostic device can independently activate the water pump and other necessary sensors without relying on the vehicle's normal operating state.

[0073] The test speed refers to a specific speed at which the vehicle's water pump is controlled to operate below its maximum speed (i.e., the upper limit of speed) during the cooling system blockage detection process. The purpose of selecting the test speed is to make an initial judgment on whether the water pump is working properly and to ensure that the coolant is starting to circulate in the system, so as to obtain more accurate water pump power and coolant temperature data later.

[0074] In response to the vehicle's power status indicating that the vehicle is powered off, the process of activating the cooling system blockage detection based on the target diagnostic equipment can be understood as follows: when the vehicle is not running (i.e., powered off), a specific diagnostic device (the target diagnostic device) can be used to manually activate the process to detect the degree of blockage in the cooling system. Typically, when the vehicle is powered off, most electrical systems are in a closed state; therefore, the target diagnostic device can be used to individually activate the water pump and related sensors to begin the detection process.

[0075] When the blockage detection process is activated, the vehicle's water pump is controlled to run at the test speed. To determine whether the vehicle's water pump is operating normally, it can be understood that when the blockage detection process is activated, the vehicle's water pump is controlled to reach a preset test speed. This is intended to preliminarily assess whether the water pump operates smoothly at this test speed and whether there is any abnormal noise or vibration, thereby determining whether the water pump is in normal working condition.

[0076] In response to the vehicle's water pump being in normal operating condition, acquiring the vehicle's water pump voltage and coolant temperature, and controlling the water pump to operate at its maximum speed and acquiring the water pump speed, can be understood as follows: Once it is confirmed that the water pump is operating normally at the test speed, the system first reads the vehicle's water pump voltage and coolant temperature. Subsequently, the system controls the water pump to accelerate to its maximum speed, then checks the water pump's response and operating status again, while simultaneously recording the vehicle's water pump speed at this point.

[0077] It can be seen that by using the target diagnostic equipment to activate the detection process when the vehicle is powered off, controlling the water pump to the test speed and maximum speed, and collecting key parameter information of the vehicle water pump, the accuracy and reliability of the system blockage detection are effectively improved.

[0078] Optionally, in step S14, the vehicle water pump voltage, vehicle water pump speed, and vehicle system coolant temperature are analyzed based on the relationship mapping table to determine the current degree of blockage in the vehicle cooling system, including the following execution steps:

[0079] Step S141: In response to the vehicle power status indicating that the vehicle is powered on, a relationship mapping table is determined based on the vehicle water pump voltage and the vehicle system coolant temperature.

[0080] Step S142: After the target time period, read the vehicle water pump power;

[0081] Step S143: Determine the current degree of blockage in the vehicle cooling system based on the relationship mapping table, vehicle water pump speed, and vehicle water pump power.

[0082] In this embodiment of the invention, the vehicle water pump power is obtained by monitoring the current and voltage of the water pump motor, and is used to represent the electrical power consumed by the vehicle water pump when it is working.

[0083] In response to the vehicle's power status indicating that the vehicle is powered on, the relationship mapping table determined based on the vehicle's water pump voltage and vehicle system coolant temperature can be understood as determining the corresponding relationship mapping table based on the current vehicle water pump voltage and vehicle system coolant temperature when the vehicle is powered on.

[0084] Reading the vehicle water pump power after the target time period can be understood as reading the actual power consumption of the vehicle water pump after the target time period of vehicle water pump operation, and after ensuring that the cooling system has reached a stable state.

[0085] Determining the current degree of blockage in a vehicle's cooling system based on a relational mapping table, vehicle water pump speed, and vehicle water pump power can be understood as using the vehicle water pump speed and power to look up the corresponding values ​​in the relational mapping table, thereby determining the current degree of blockage in the vehicle's cooling system.

[0086] As can be seen, with the vehicle powered on, a mapping table is first established based on the vehicle's water pump voltage and coolant temperature to provide a benchmark for subsequent analysis. Then, after the system reaches a target stable state within a certain timeframe, the actual power of the vehicle's water pump is read. Finally, by combining the mapping table, vehicle water pump speed, and vehicle water pump power data, the degree of cooling system blockage is accurately assessed. This achieves efficient and accurate detection of cooling system blockage, facilitating timely maintenance, ensuring vehicle operational safety, simplifying the detection process, and reducing costs.

[0087] Figure 2 This is a flowchart of a method for determining the degree of blockage in a vehicle's cooling system when powered on, according to one embodiment of the present invention. Figure 2 As shown, the process first puts the vehicle under high-voltage power. Then, based on the vehicle's control logic, it determines whether the water pump is operating normally. If the water pump is operating normally, after one minute of operation, the pump voltage, pump speed, pump power, and system coolant temperature are read. If the water pump is not operating normally, a fault code is reported after the detection program exits. A corresponding mapping table is determined based on the pump voltage and system coolant temperature. Then, based on the mapping table, pump speed, and pump power, it is determined whether the vehicle's cooling system is blocked. If a blockage is detected, the degree of blockage and the vehicle identification number are reported to the cloud platform for maintenance personnel to inspect, thus preventing users from driving aggressively and causing safety accidents. If no blockage is detected, the detection process exits.

[0088] Optionally, in step S14, the vehicle water pump voltage, vehicle water pump speed, and vehicle system coolant temperature are analyzed based on the relationship mapping table to determine the current degree of blockage in the vehicle cooling system, including the following execution steps:

[0089] Step S144: In response to the vehicle power status indicating that the vehicle is in a powered-off state, a relationship mapping table is determined based on the vehicle water pump voltage and the vehicle system coolant temperature.

[0090] Step S145: When the vehicle water pump reaches its maximum speed limit, read the vehicle water pump power.

[0091] Step S146: Determine the current degree of blockage in the vehicle cooling system based on the relationship mapping table, vehicle water pump speed, and vehicle water pump power.

[0092] In this embodiment of the invention, in response to the vehicle power status indicating that the vehicle is in a powered-off state, determining the relationship mapping table based on the vehicle water pump voltage and the vehicle system coolant temperature can be understood as determining the corresponding relationship mapping table based on the current vehicle water pump voltage and the vehicle system coolant temperature when the vehicle is powered off.

[0093] When the vehicle water pump is running at its maximum speed, reading the vehicle water pump power can be understood as controlling the vehicle water pump to run at its maximum speed and reading the vehicle water pump power at that time.

[0094] Determining the current degree of blockage in a vehicle's cooling system based on a relational mapping table, vehicle water pump speed, and vehicle water pump power can be understood as follows: by looking up the degree of blockage corresponding to the current vehicle water pump speed and power in the relational mapping table, the current degree of blockage in the vehicle's cooling system can be determined.

[0095] As can be seen, when the vehicle is powered off, a relationship mapping table is first determined based on the vehicle water pump voltage and the vehicle system coolant temperature. Then, the vehicle water pump power is obtained when the vehicle water pump is controlled to run at its maximum speed. Finally, the current degree of blockage in the vehicle cooling system is determined by looking up the corresponding values ​​in the relationship mapping table based on the vehicle water pump speed and vehicle water pump power. This not only simplifies the detection process of the degree of blockage in the vehicle cooling system and reduces the implementation cost, but also significantly improves the accuracy and reliability of the detection.

[0096] Figure 3 This is a flowchart of a method for determining the degree of blockage in a vehicle's cooling system when the vehicle is powered off, according to one embodiment of the present invention. Figure 3 As shown, when the vehicle is powered off, the diagnostic tool first sends an activation command to initiate the cooling system blockage detection process. Next, the vehicle's water pump is controlled to run at a specific speed to check if it operates normally and ensures coolant circulation, guaranteeing accurate system temperature readings from the temperature sensor. If the water pump operates normally, the pump voltage and coolant temperature are read; if it fails, the detection program exits and a corresponding fault code is provided for operator review. Then, the water pump is controlled to run at maximum speed, and its speed and power are read. Based on the relationship mapping table, pump speed, and power, the presence of blockage in the vehicle's cooling system is determined. If a blockage is detected, the degree of blockage is reported and repaired; if no blockage is detected, the detection program exits.

[0097] Optionally, the method for determining the degree of blockage in the vehicle cooling system may further include the following steps:

[0098] Step S15: Under any degree of blockage, any vehicle water pump voltage, and any vehicle system coolant temperature, control the vehicle water pump to run at any speed and read the corresponding vehicle water pump power.

[0099] Step S16: Under any vehicle water pump voltage and any vehicle system coolant temperature, based on any degree of blockage, any speed and the corresponding vehicle water pump power, establish a mapping table to reflect the relationship between the degree of blockage of the vehicle cooling system and the vehicle water pump power.

[0100] In this embodiment of the invention, controlling the vehicle water pump to run at any speed under any degree of blockage, any vehicle water pump voltage, and any vehicle system coolant temperature, and reading the corresponding vehicle water pump power can be understood as placing the vehicle water pump under different degrees of blockage, and controlling the vehicle water pump to run at any set speed under different vehicle water pump voltages and different vehicle system coolant temperatures, and then recording the vehicle water pump power under the corresponding conditions.

[0101] Under any vehicle water pump voltage and any vehicle system coolant temperature, based on any degree of blockage, any speed, and the corresponding vehicle water pump power, establishing a mapping table to reflect the relationship between the degree of blockage of the vehicle cooling system and the vehicle water pump power can be understood as follows: by integrating the corresponding vehicle water pump power, the corresponding degree of blockage of the vehicle cooling system, and the corresponding vehicle water pump speed collected in step S15 under different vehicle water pump voltages and different vehicle system coolant temperatures, several mapping tables can be established to show how different degrees of blockage affect the power consumption of the water pump at different speeds under any given voltage and temperature environment.

[0102] As can be seen, by constructing a relational mapping table, the system can quickly and accurately assess the status of the vehicle cooling system based on the relational mapping table, thereby predicting and handling problems in advance and ensuring vehicle performance and driving safety.

[0103] Optionally, the method for determining the degree of blockage in the vehicle cooling system may further include the following steps:

[0104] Step S17: In response to the current level of blockage indicating a blockage in the vehicle's cooling system, the level of blockage and fault codes are fed back for the operator to view and troubleshoot.

[0105] In this embodiment of the invention, the fault code is a standardized error information encoding method that can accurately locate the problem and prompt the operator with the specific fault type, such as a blockage in the cooling system.

[0106] The system responds to the current level of blockage, indicating that there is a blockage in the vehicle's cooling system. It provides the operator with information on the level of blockage and fault codes for review and repair. This means that once the system determines that there is a blockage in the vehicle's cooling system, it will provide the operator with information on the level of blockage and fault codes, and then take appropriate maintenance measures, such as cleaning the system, replacing the filter, or checking the water pump status. There are no restrictions on this.

[0107] As can be seen, if there is a blockage in the vehicle's cooling system, the degree of blockage and fault codes are provided for the operator to view and repair, ensuring that the problem is detected and resolved in a timely manner. This reduces the vehicle's performance degradation and potential safety risks caused by the blockage in the cooling system, while also optimizing maintenance efficiency and improving the user experience.

[0108] Figure 4 This is a simplified schematic diagram of a motor system according to one embodiment of the present invention, such as... Figure 4 As shown, the system includes a motor-driven water pump, motor assembly, motor radiator, and motor coolant temperature sensor. Taking a specific operating condition as an example, when the vehicle water pump voltage is 13.5V and the vehicle coolant temperature is 25℃, the relationship between different degrees of cooling system blockage and the vehicle water pump power and speed is shown in Table 1, based on system bench testing. The test results show that when the vehicle water pump speed is at its maximum, the difference in water pump power is significant for different degrees of system blockage. Therefore, when the vehicle is powered off, controlling the water pump to its maximum speed before judging system blockage can improve the accuracy and precision of the detection.

[0109] Specifically, when the vehicle is powered off, the first step is to activate the vehicle's cooling system blockage detection process using a diagnostic tool or other diagnostic equipment. Next, the electric motor water pump is controlled to run at 50% speed for 10 seconds to circulate the coolant and ensure the water temperature sensor reflects the actual system temperature, confirming the water pump is operating normally. At this time, the vehicle's electric motor water pump voltage is measured at 13.5V and the coolant temperature at 25°C. Then, the vehicle's water pump is controlled to run at maximum speed, and the water pump power is read as 140W. Based on the maximum water pump speed and power, the blockage level in Table 1 is determined to be 30%. The blockage level and fault code are then reported to the operator to check for any obstructions in the vehicle's cooling system.
