[0047] In order to better understand the technical solution of the present invention, the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0048] It should be clear that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0049] The terms used in the embodiments of the present invention are only for the purpose of describing specific embodiments, and are not intended to limit the present invention. The singular forms "a", "said" and "the" used in the embodiments of the present invention and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.

[0050] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0051] With the rapid development of new energy vehicle technology, the increase in high and low voltage accessories makes the thermal management system more complex than that of traditional fuel vehicles. Especially in the thermal management of motor electronic control and battery, the cooling requirements of these key components have a decisive impact on vehicle performance and life. In order to more accurately control the engine cycle temperature, many hybrid vehicles have upgraded the traditional mechanical water pump to an electronic water pump. This upgrade not only improves the accuracy of temperature control, but also brings about energy efficiency improvement.

[0052] However, when a new energy vehicle is parked for a long time or the engine is not started for a long time, the water pump may be damaged due to various reasons. For example:

[0053] 1) Long-term parking may cause accumulation of impurities, scale, etc. in the cooling system, thereby clogging the water pump.

[0054] 2) The seal of the water pump may be damaged due to aging or long-term non-use, causing coolant leakage.

[0055] 3) The impeller, shaft and other parts inside the pump may rust or be damaged due to long-term non-operation, affecting the pumping capacity of the pump.

[0056] These problems may cause the water pump to work abnormally or even fail completely when it is restarted. Therefore, the present invention provides a method for controlling the operation of a water pump to solve the above problems.

[0057] Please refer to Figure 1 , which is a flow chart of a method for controlling the operation of a water pump provided by an embodiment of the present invention, comprising the following steps:

[0058] Step S01, obtaining water pump start and stop information.

[0059] In this embodiment, the water pump start and stop information refers to detailed data and status records about the start and stop of the water pump. The water pump start and stop information may specifically include:

[0060] Start time: The specific time when the pump starts running each time.

[0061] Stop time: The specific time when the pump stops running each time.

[0062] Running time: The running time of the pump from the start to the stop.

[0063] Number of starts: The total number of times the pump starts within a certain period of time.

[0064] Operating status: the status of the pump during operation, such as normal operation, fault status, etc.

[0065] Fault information: If the pump fails during operation, the relevant fault code and description.

[0066] Environmental conditions: Environmental factors that may affect the operation of the pump, such as temperature, pressure, etc.

[0067] The purpose of obtaining the water pump start and stop information in this embodiment is that, by analyzing the water pump start and stop information, the system can determine whether the water pump needs maintenance. For example, after the water pump has not been started or stops working for a long time, the system can automatically trigger the maintenance program to prevent the water pump from failing due to long-term non-use, such as aging of seals, rusting of internal components and other problems, thereby improving the reliability and service life of the water pump.

[0068] In some embodiments, obtaining the start and stop information of the water pump can be achieved through sensors and a vehicle control unit (VCU), where the sensors are installed on the water pump and its related components to detect the operating status of the water pump in real time. When the water pump starts or stops, the sensor will immediately send a signal to the VCU, which will then record the specific time points of these state changes. In addition, the VCU can also continuously track the operating data of the water pump, including the frequency of starting and stopping, the duration of each operation, and any abnormal conditions.

[0069] Step S02, judging whether to enter the water pump maintenance mode according to the water pump start and stop information.

[0070] If yes, execute step S03.

[0071] In this embodiment, the start and stop records of the water pump are analyzed to determine whether the water pump needs maintenance. Specifically, the system monitors the running frequency, duration and downtime of the water pump. When these parameters exceed the preset threshold or show abnormal patterns, the system determines that the water pump needs maintenance.

[0072] For example, when the system detects that the water pump has reached a predetermined maintenance time interval (the maintenance time interval can be set according to the water pump capacity, such as 60 days or 90 days), it will automatically trigger to enter the water pump maintenance mode. In the water pump maintenance mode, the system executes step S03 to detect whether there is a fault in the water pump operation component.

[0073] In some embodiments, when it is determined that the water pump maintenance mode is not to be entered according to the water pump start and stop information, the system can also return to step S01 to continue to obtain the water pump start and stop information. This design allows the system to perform continuous cyclic monitoring to ensure that the operating status of the water pump is always under monitoring.

[0074] Step S03, detecting whether there is any fault in the water pump operating component.

[0075] If not, execute step S04.

[0076] The water pump operation component may include an electronic water pump, a battery management system, an electronic control unit, and a vehicle control unit.

[0077] In this embodiment, if it is detected that there is no fault in the water pump operation component, step S04 is executed to control the water pump operation component to enter the operation state. Fault detection can ensure that the water pump operation component is safely started and operated in the water pump maintenance mode. If there is a fault in the water pump or its components, forced operation may cause more serious damage and may even affect the performance and safety of the entire vehicle. By identifying whether there is a fault in the water pump operation component in advance, damage to the water pump caused by component failure can be prevented, and secondary damage during the operation of the water pump, such as engine overheating or other system failures, can be avoided. Through this preventive maintenance, the reliability of the water pump can be significantly improved and its service life can be extended.

[0078] In some embodiments, the system can collect real-time data about the electronic water pump, battery management system (BMS), electronic control unit (ECU) and VCU through sensors, including but not limited to key parameters such as temperature, pressure, current, voltage and speed. The ECU or VCU will then compare this data with the preset normal operating parameters and analyze whether there is an abnormality through the built-in fault diagnosis algorithm. If any parameter is detected outside the normal range, the system confirms that there is a fault in the water pump operation component.

[0079] In some embodiments, after detecting whether the water pump operating component has a fault, the following steps may be performed:

[0080] When there is a fault in the pump operating components, the fault information is sent to the cloud through the intelligent network system.

[0081] This embodiment can transmit fault information (including fault code, occurrence time, status data of faulty components, etc.) to the cloud server through the intelligent network connection system. After receiving the fault notification through the mobile device or the vehicle information system, the user can quickly understand the specific problem of the vehicle and make corresponding countermeasures, such as contacting the service station or arranging repairs. At the same time, after the technician obtains the detailed fault data in the cloud, he can conduct in-depth analysis to determine the severity of the fault and possible repair solutions. This remote diagnosis capability enables service providers to prepare the necessary tools and accessories in advance, optimize the maintenance process, and reduce the maintenance time of the vehicle.

[0082] Step S04, controlling the water pump operation component to enter the operation state.

[0083] In this embodiment, after confirming that the water pump operating components are free of faults and in good working condition, the electronic water pump is started through the vehicle's intelligent control system. This process includes sending instructions to the electronic control unit of the electronic water pump to activate the water pump motor and start pumping coolant to allow the coolant to flow in the pipeline.

[0084] In some embodiments, as mentioned in step S04, controlling the water pump operation component to enter the operation state may specifically include the following steps:

[0085] Step S11 : the vehicle control unit requests that the vehicle state is a high pressure state, and obtains the control type of the electronic water pump.

[0086] In this embodiment, the VCU first issues a command requiring the vehicle's power system to enter a high-voltage state so that the battery pack supplies power to the vehicle's high-voltage system and provides the necessary power for the water pump operating components. Subsequently, the VCU will identify the control type of the electronic water pump, and there are two control types: PWM (pulse width modulation) control type and speed control type. The PWM control type controls the speed and flow of the water pump by adjusting the duty cycle of the electronic signal, while the speed control type directly controls the speed of the water pump. This allows the VCU to send the correct control signal according to the control type to ensure that the water pump can operate in the correct manner.

[0087] Step S12: If the control type of the electronic water pump is the PWM waveform control type, the electronic water pump is controlled to operate at a 50% duty cycle.

[0088] In this embodiment, the speed and flow rate of the PWM control type electronic water pump are achieved by adjusting the duty cycle of the motor drive signal. The duty cycle refers to the proportion of time that the signal is in a high level state within a certain period of time. When the duty cycle is 50%, it means that the motor receives a high level signal for half of the time and a low level signal for the other half of the time.

[0089] By setting the duty cycle to 50%, the electronic water pump will run at a moderate speed, ensuring that no excessive energy is consumed and no excessive wear and tear is caused to the water pump. This control method allows the water pump to run at a lower load, helping to extend its service life.

[0090] Step S13: if the control type of the electronic water pump is the speed control type, the electronic water pump is controlled to run at half speed.

[0091] In this embodiment, the speed of the speed-controlled electronic water pump is directly controlled by the electronic control unit or the vehicle control unit. When the system recognizes that the water pump needs maintenance, the electronic control unit will issue an instruction to adjust the running speed of the water pump to half of its maximum design speed.

[0092] This half-speed control allows the water pump to operate at a lower load, helping to reduce energy consumption while avoiding excessive wear on the water pump and its related components. By operating at half speed, the water pump is able to perform the necessary coolant circulation to simulate the working conditions of the water pump in actual vehicle operation, but at a lower intensity, which helps to effectively maintain and inspect the water pump and its related systems without adding additional burden, thereby extending the service life of the water pump.

[0093] In some embodiments, after the electronic water pump is started, the system will continue to monitor the operating parameters of the water pump to ensure that it operates stably within a predetermined operating range. This includes monitoring the speed, flow, pressure, and temperature of the water pump to ensure that when the water pump encounters a problem during operation, the system will be able to respond in a timely manner and take necessary measures, such as adjusting operating parameters or triggering a fault alarm, to ensure the safety and performance of the vehicle.

[0094] Based on the above technical solution, the method for controlling the operation of the water pump provided in the embodiment of the present invention determines whether to enter the water pump maintenance mode according to the water pump start and stop information; if so, detects whether there is a fault in the water pump operation component; if there is no fault, controls the water pump operation component to enter the operation state. The present invention effectively prevents the problem of water pump damage caused by long-term parking or non-starting by monitoring the start and stop status of the water pump in real time, intelligently judging and triggering the maintenance mode, which can not only significantly improve the reliability and durability of the water pump, but also reduce the maintenance cost caused by water pump failure. Moreover, by comprehensively evaluating whether there is a fault in the water pump operation component, the system will control the water pump operation component to enter the operation state only when it is confirmed that the water pump operation component is not faulty, thereby optimizing energy use, extending the service life of the water pump, and ensuring the safety and effectiveness of the maintenance process. In this way, the probability of water pump failure is reduced, and the overall performance and user satisfaction of new energy vehicles are improved.

[0095] Please refer to Figure 2 ,for Figure 1 A flowchart of an actual performance of S02 in a method for controlling water pump operation is provided. In some embodiments, the process mentioned in step S02, judging whether to enter the water pump maintenance mode according to the water pump start and stop information, may specifically include the following steps: Figure 2 Steps shown:

[0096] Step S21, determining the water pump shutdown time according to the water pump start and stop information.

[0097] In this embodiment, the water pump start and stop information is analyzed to identify the specific time when the water pump stopped working for the last time. Then, the need for maintenance is evaluated based on the downtime of the water pump. By accurately recording the downtime of the water pump, the vehicle's intelligent network system can manage maintenance plans more effectively, ensuring that the water pump is inspected and maintained at the appropriate time, thereby extending its service life.

[0098] Step S22, obtaining the current time through the intelligent network system, and calculating the time difference between the current time and the time when the water pump is shut down.

[0099] In this embodiment, the current accurate time of the vehicle is obtained through an intelligent network connection system, such as a GPS clock or a network time protocol. Then, the system compares the current time with the previously recorded water pump shutdown time and calculates the time difference between the two. This time difference is used to subsequently determine whether the water pump needs maintenance.

[0100] Step S23, determining whether the time difference is greater than a first preset value.

[0101] If yes, execute step S24; if no, execute step S25.

[0102] In this embodiment, the first preset value is a preset time threshold used to determine whether the water pump needs maintenance. The first preset value is determined based on factors such as the normal use cycle of the water pump, maintenance requirements, and operating conditions of the vehicle. It represents the maximum time interval that the water pump can maintain without running. If this time interval is exceeded, the water pump may need maintenance to ensure its normal operation.

[0103] In this embodiment, the time difference is evaluated by a first preset value to determine whether the water pump needs maintenance. If the calculated time difference is greater than a preset threshold, this means that the water pump may have not been running for a long time and maintenance is required to ensure its normal operation. In this case, the system will execute step S24 to start the water pump maintenance mode. This may include inspection, testing and necessary maintenance operations on the water pump and its related components to ensure that the water pump can operate reliably when needed.

[0104] If the time difference does not exceed the preset threshold, it indicates that the downtime of the water pump is still within an acceptable range and no immediate maintenance is required. In this case, the system will execute step S25 to put the vehicle into sleep mode. Sleep mode is an energy-saving state in which non-essential systems of the vehicle will be shut down or reduced in power to reduce energy consumption and keep the vehicle in standby mode.

[0105] Step S24, entering the water pump maintenance mode.

[0106] Step S25, entering the vehicle sleep mode.

[0107] Based on the above technical solution, this embodiment calculates the time difference between the water pump shutdown time and the current time and compares it with the preset value, so as to timely discover potential problems that may occur in the water pump due to long-term shutdown, so as to perform maintenance in advance and avoid water pump damage. At the same time, when the water pump does not need maintenance, the system will enter the vehicle sleep mode, which helps to reduce unnecessary energy consumption and improve energy efficiency.

[0108] Please refer to Figure 3 , which is a flow chart of another method for controlling the operation of a water pump provided by an embodiment of the present invention. In some embodiments, after executing step S04 to control the water pump operation component to enter the operation state, the following steps may also be performed: Figure 3 Steps shown:

[0109] Step S31, obtaining the operating time of the water pump operating component.

[0110] In this embodiment, the system measures and records the total running time of the water pump and its related components from start to stop through the vehicle's intelligent monitoring system or vehicle control unit. This process includes accurately time-stamping the start and stop times of the water pump, thereby calculating the actual working time of the water pump during a maintenance cycle. By monitoring the running time, the system can determine whether the water pump has reached the time threshold for maintenance, and thus decide whether to perform maintenance procedures or shut it down.

[0111] Step S32, determining whether the running time exceeds a second preset value.

[0112] If yes, execute step S33.

[0113] In this embodiment, the second preset value is determined based on the design parameters, durability and best maintenance practices of the water pump, and is used to represent the maximum operating time allowed for the water pump in the water pump maintenance mode. By comparing the operating time of the water pump with the second preset value, the system can determine whether the water pump has been running for a sufficient time, thereby deciding whether it needs to be shut down to avoid overheating, wear or other possible damage.

[0114] Step S33, controlling the water pump operation component to exit the operation state and exit the water pump maintenance mode.

[0115] In this embodiment, when the water pump completes the necessary maintenance operation or reaches the preset operation time limit, the vehicle control unit issues an instruction to stop the operation of the water pump. This process includes sending a control signal to the electronic control unit of the water pump, instructing it to completely stop the operation of the water pump.

[0116] At the same time, exiting the water pump maintenance mode means that the vehicle will switch from the maintenance state back to the normal operating state, at which time the water pump will operate according to the actual cooling needs of the vehicle instead of the scheduled operating time in the maintenance mode.

[0117] Step S34, updating the water pump start and stop information.

[0118] In this embodiment, after the water pump completes the maintenance operation, the vehicle control unit refreshes and records the start and stop records of the water pump to ensure that the pump start and stop information is up to date. By updating the water pump start and stop information, the system can more accurately monitor the use pattern and maintenance needs of the water pump, providing an important basis for future maintenance plans. In addition, the updated records also help to perform fault diagnosis when necessary, quickly locate the problem, and thus improve maintenance efficiency.

[0119] Based on the above embodiments, in some embodiments, when there is no fault in the water pump operation component, the following steps may also be performed:

[0120] Step S41, controlling the vehicle gear to be in the OFF gear, and controlling the non-water pump operation components to be in a dormant state.

[0121] Among them, the non-water pump operation components include at least one of an entertainment component, an information display component, a lighting component, and an air conditioning component.

[0122] In this embodiment, during the water pump maintenance, the vehicle gear is first ensured to be in the OFF gear, that is, the vehicle's transmission system is disconnected and the engine does not run, thereby avoiding accidental start during the maintenance process. At the same time, the non-water pump operation components in the vehicle are controlled to be in a dormant state. This not only reduces energy consumption, but also reduces the interference or impact that these systems may cause to the water pump maintenance during the maintenance period.

[0123] Step S42, maintaining the vehicle network through the vehicle control unit.

[0124] In this embodiment, the vehicle control unit serves as the central processing and control center of the vehicle and is responsible for managing and coordinating the information exchange between various electronic control units in the vehicle.

[0125] Based on the above embodiments, in some embodiments, the following steps may also be performed:

[0126] When the water pump operation component exits the operation state, the vehicle control unit enters the power-off mode and requests the vehicle state to be the sleep state.

[0127] In this embodiment, by entering the power-down mode, non-essential systems and components of the vehicle will be shut down, thereby reducing energy consumption. At the same time, after requesting the vehicle state to be in a dormant state, non-essential systems and components will not continue to run in the dormant state, which helps to reduce wear and tear and extend the overall service life of the vehicle's electronic system.
