[0005] To achieve the above objectives, according to a first aspect of this application, a method for controlling a water valve is provided, comprising:

[0006] Obtain the operational requirements of the water circuit corresponding to the water valve;

[0007] When the aforementioned operational requirement is met, the water valve is controlled to rotate toward the target position according to the minimum resistance rotation strategy;

[0008] When there is no operational requirement, control the water valve to rotate to the position of minimum resistance.

[0009] Optionally, the minimum resistance rotation strategy includes keeping the water pump corresponding to the water valve in a closed state;

[0010] The control of the water valve to rotate to the target position according to the minimum resistance rotation strategy includes:

[0011] In response to a preset command controlling the rotation direction of the water valve, the operating state of the water pump is determined;

[0012] When the water pump is in the off state, control the water valve to rotate to the target position;

[0013] When the water pump is in the running state, the water pump is controlled to shut down, and after the water pump is shut down, the water valve is controlled to rotate to the target position.

[0014] Optionally, the method further includes:

[0015] When the water valve is rotated to the target position, the water pump is controlled to switch from the off state to the running state.

[0016] Optionally, controlling the water valve to rotate to the target position after the water pump is turned off includes:

[0017] When the water pump shut-off time meets the first preset duration, the water valve is controlled to rotate to the target position.

[0018] Optionally, after the step of controlling the water valve to rotate to the target position according to the minimum resistance rotation strategy, the method further includes:

[0019] When the rotation time of the water valve is greater than or equal to the second preset time and the water valve has not rotated to the target position, the water valve is controlled to stop rotating and the fault information of the water valve is reported.

[0020] Optionally, the water valve includes at least two valve ports;

[0021] When the water valve is rotated to the position of minimum resistance, all valve ports of the water valve are in the conducting state.

[0022] Optionally, the method further includes:

[0024] Optionally, before obtaining the operational requirements of the water circuit corresponding to the water valve, the method further includes:

[0025] When the water valve is in a faulty state, the acquisition of the operating requirements of the water circuit corresponding to the water valve is stopped, and the fault information of the water valve is reported.

[0026] When the water valve is in a fault-free state, the step of obtaining the operating requirements of the water circuit corresponding to the water valve is executed.

[0027] According to a second aspect of this application, a computer-readable storage medium is provided that stores a computer program thereon, which, when executed by a processor, implements the steps of the aforementioned method.

[0031] In summary, in this embodiment, the minimum resistance rotation strategy refers to the strategy that minimizes the resistance experienced by the valve core during its rotation towards the target position. Thus, the valve core is less prone to deformation during rotation, resulting in a smaller deformation and extending the lifespan of the water valve. The minimum resistance position refers to the position where the resistance experienced by the valve core is minimal. Similarly, when the valve core is at the minimum resistance position, it is less prone to deformation, further minimizing deformation and extending the lifespan of the water valve.

[0040] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0041] like Figure 1 As shown, the water system is an example application scenario of the control method of water valve 200. The water system includes a vehicle controller, a motor controller, a temperature sensing module, a water circuit, a water pump 100 installed in the water circuit, a water valve 200 installed in the water circuit, a first heat exchange object installed in the water circuit, and a second heat exchange object installed in the water circuit.

[0042] The motor controller can report fault information of water valve 200 to the vehicle controller. The motor controller can receive signals from the temperature sensing module, which is used to detect the temperature of the first and second heat exchange objects. The vehicle controller can control the operation and shutdown of water pump 100.

[0043] In practical use, the temperature sensing module detects the temperature of the object to be heat-exchanged, which can be either the first heat exchange object 300 or the second heat exchange object 400, and sends this temperature information to the vehicle controller. The vehicle controller then determines whether to perform heating or cooling operations on the object through the control water system based on the temperature information. When the vehicle controller determines to perform heating or cooling operations on the object through the control water system based on the temperature information, it can be understood that the object has a corresponding operational requirement for the water circuit corresponding to water valve 200. That is, when the vehicle controller determines to perform heating or cooling operations on the object through the control water system based on the temperature information, it can send corresponding requirement information to the motor controller, instructing the motor controller to control the operation of the water system to perform heating or cooling operations on the object.

[0044] Here, the motor controller controls the operation of the water system. During the heating or cooling operation of the object to be heated, one or more water valves 200 can be installed in the water system to divide it into multiple water channels. In this way, by controlling the rotation of the water valves 200, different water channels can be opened to heat or cool different objects to be heated.

[0045] The water valve 200 includes a motor, a valve core, and multiple valve ports 240. A motor controller is used to control the motor of the water valve 200. Rotation of the water valve 200 means the motor controls the rotation of the valve core, which in turn controls the opening degree of the multiple valve ports 240. The smaller the opening degree of a valve port 240, the smaller the water flow rate through that port 240. When the opening degree of a valve port 240 is at its minimum, the valve core blocks that port 240, meaning that port 240 is closed.

[0046] The multiple valve ports 240 include a first valve port 210, a second valve port 220, and a third valve port 230. For example... Figure 2 As shown, when the first valve port 210 and the second valve port 220 are open and the third valve port 230 is closed, the water pump 100 can drive the water flow to flow sequentially through the first valve port 210, the second valve port 220 and the first heat exchange object, and then return from the first heat exchange object to the water pump 100.

[0047] like Figure 3 As shown, when the first valve port 210 and the third valve port 230 are open and the second valve port 220 is closed, the water pump 100 can drive the water flow to flow sequentially through the first valve port 210, the third valve port 230 and the second object to be heat exchanged, and then return from the second object to be heat exchanged to the water pump 100.

[0048] like Figure 4 As shown, when the first valve port 210, the second valve port 220, and the third valve port 230 are connected, the water pump 100 can drive water to enter the water valve 200 from the first valve port 210, and then flow out of the water valve 200 from the second valve port 220 and the third valve port 230 respectively. The water flowing out from the second valve port 220 will flow through the first heat exchange object, and then flow back from the first heat exchange object to the water pump 100. The water flowing out from the third valve port 230 will flow through the second heat exchange object, and then flow back from the second heat exchange object to the water pump 100.

[0049] The first object to be heat exchanged may be, but is not limited to, an engine, battery, electric drive system, air conditioner, or passenger compartment, etc.; the second object to be heat exchanged may also be, but is not limited to, an engine, battery, electric drive system, air conditioner, or passenger compartment, etc.

[0050] Please see Figure 5 This application provides a control method for a water valve 200. The control method for the water valve 200 provided in the embodiments of this application includes steps S100-S300, which will be described in detail below.

[0051] Step S100: Obtain the operating requirements of the water circuit corresponding to water valve 200.

[0052] The operational requirements of the water system refer to whether there is a demand for the water system in the application environment or usage scenario where the water valve 200 is located.

[0053] In the above application scenario, taking the first object to be heat exchanged as an example, if the temperature sensing module detects that the temperature of the first object to be heat exchanged is lower than the first preset temperature, it indicates that the first object to be heat exchanged is too cold and needs to be heated, requiring the use of the water circuit. The vehicle controller needs to control the pump to operate, and the flowing water will heat the first object to be heat exchanged. If the temperature of the first object to be heat exchanged is detected to be higher than the second preset temperature, it indicates that the first object to be heat exchanged is overheated and needs to be cooled, requiring the use of the water circuit. The vehicle controller needs to control the pump to operate, and the flowing water will dissipate heat from the first object to be heat exchanged. If the temperature of the first object to be heat exchanged is detected to be greater than or equal to the first preset temperature and less than or equal to the second preset temperature, it indicates that the temperature of the first object to be heat exchanged is suitable, and there is no need to use the water circuit. The vehicle controller needs to control the pump to shut down, so that the water flow rate approaches zero. The first preset temperature is lower than the second preset temperature. The first and second preset temperatures can be set according to the performance of the first object to be heat exchanged and are not limited here. The motor controller obtains the operating requirements of the water circuit corresponding to water valve 200 through the temperature sensing module.

[0054] In step S200, when there is an operational need, the control water valve 200 is rotated to the target position according to the minimum resistance rotation strategy.

[0055] The minimum resistance rotation strategy refers to the strategy that minimizes the resistance experienced by the valve core during its rotation toward the target position.

[0056] In this way, the valve core is less prone to deformation during its rotation toward the target position, which results in a smaller deformation of the valve core, which in turn helps to minimize the deformation of the water valve 200 and extend its service life.

[0057] In the above application scenario, when the temperature sensing module detects that the temperature of the first heat exchange object is lower than the first preset temperature, the motor controller controls the valve core to rotate toward the target position according to the minimum resistance rotation strategy, so that the valve body opens the first valve port 210 and the second valve port 220, thereby allowing water to flow through the first heat exchange object and heat the first heat exchange object.

[0058] In step S300, when there is no operational demand, control the water valve 200 to rotate to the position of minimum resistance.

[0059] The position of minimum resistance refers to the position where the valve core experiences the least resistance.

[0060] In this way, when the valve core is in the position of minimum resistance, the valve core is not easily deformed, which makes the deformation of the valve core smaller, which is beneficial to make the deformation of the water valve 200 smaller and extend the service life of the water valve 200.

[0061] In the above application scenario, when the temperature sensing module detects that the temperature of the first object to be heat exchanged is greater than or equal to the first preset temperature and less than or equal to the second preset temperature, the motor controller controls the valve core to rotate to the position of minimum resistance.

[0062] In some embodiments, the minimum resistance rotation strategy includes having the water pump 100 corresponding to the water valve 200 in a closed state, and controlling the water valve 200 to rotate to the target position according to the minimum resistance rotation strategy, including:

[0063] In response to a preset command controlling the rotation direction of the water valve 200, the operating state of the water pump 100 is determined;

[0064] The preset command for the rotation direction of water valve 200 can be a preset command for controlling the reversal of water flow or a preset command for controlling the flow rate, and there are no restrictions here.

[0065] When the water pump 100 is in the off state, the control water valve 200 rotates to the target position.

[0066] When the water pump 100 is in the running state, control the water pump 100 to shut down, and after the water pump 100 is shut down, control the water valve 200 to rotate to the target position.

[0067] It is understandable that if the water pump 100 is running while the valve core is rotating towards the target position, the water flow velocity is high, resulting in a greater impact force on the valve core. This can easily cause deformation of the valve core and reduce its service life. Furthermore, the motor requires a large torque to drive the valve core, and the force transmitted from the water flow through the valve core to the motor is significant, potentially reducing the motor's lifespan. To reduce the stress on the valve core and motor, when the water pump 100 is off, the motor controller controls the valve core's rotation. This prevents the water flow from being driven by the water pump 100, reducing the impact on the valve core and consequently the impact on the water valve 200. It also reduces the force transmitted from the water flow through the valve core to the motor, minimizing resistance during the rotation of the water valve 200. This reduces the degree of deformation of the water valve 200, thereby extending its service life.

[0068] However, this design is not limited to this. In some other embodiments, the minimum resistance rotation strategy can be other strategies, which are not limited here, as long as the strategy minimizes the resistance experienced by the valve core during the rotation of the valve core towards the target position.

[0069] In some embodiments, the method further includes:

[0070] When the water valve 200 is rotated to the target position, the water pump 100 is switched from the closed state to the running state.

[0071] Thus, water pump 100 starts operating to meet the operational needs of the water circuit in a timely manner.

[0072] It is understandable that if the water valve 200 is far from the water pump 100, at the moment the water pump 100 is turned off, although the water flow loses the power provided by the water pump 100, the water flow to the water valve 200 still has a relatively high flow velocity. In order to reduce the large resistance encountered by the water valve 200 during the process of rotating to the target position, in some embodiments, the water valve 200 is controlled to rotate to the target position after the water pump 100 is turned off, including:

[0073] When the shut-off time of the water pump 100 meets the first preset duration, the control water valve 200 rotates to the target position.

[0074] Thus, within the first preset duration, without the driving force provided by the water pump 100, the water flow velocity will approach zero, reducing the resistance encountered by the water valve 200 during its rotation to the target position, thereby reducing the degree of deformation of the water valve 200 and extending its service life. The first preset duration can be set according to actual conditions, such as, but not limited to, setting based on empirical values. In one example, the first preset duration can be configured as 2 seconds.

[0075] However, this design is not limited to this. In some embodiments, some water valves 200 are closer to the water pump 100. When the water pump 100 is closed, the flow rate to the water valve 200 tends to zero. The water valve 200 can be controlled to rotate to the target position at the same time as the water pump 100 is closed.

[0076] In some embodiments, after the step of controlling the water valve 200 to rotate toward the target position according to a minimum resistance rotation strategy, the method further includes:

[0077] If the rotation time of water valve 200 is greater than or equal to the second preset time, and water valve 200 has not rotated to the target position, control water valve 200 to stop rotating and report fault information of water valve 200.

[0078] The second preset duration can be set according to actual conditions. For example, if factors such as aging of the water valve 200 cause it to rotate slowly and require a longer time to reach the target position, the second preset duration can be set to a longer value. In one example, the second preset duration can be configured to 15 seconds.

[0079] If the rotation time is greater than or equal to the second preset time, it indicates that the water valve 200 is in a faulty state, and the water valve 200 is controlled to stop rotating to save energy. In addition, the motor controller reports the fault information of the water valve 200 to the vehicle controller, so that the water valve 200 can be repaired in a timely manner.

[0080] In the above application scenario, the water valve 200 may be unable to rotate due to foreign objects, thus failing to rotate to the target position within a second preset time period. When the rotation time is greater than or equal to the second preset time period, the water valve 200 is controlled to stop rotating. This can prevent the water valve 200 from being squeezed by foreign objects, thereby reducing the occurrence of further damage to the water valve 200 and extending the service life of the water valve 200.

[0081] In some embodiments, the water valve 200 includes at least two valve ports 240. When the water valve 200 is in the position of minimum resistance, all valve ports 240 of the water valve 200 are in a conductive state. In this way, the valve core is disengaged from the valve ports 240, avoiding mutual compression between the valve core and the valve ports 240, reducing the degree of deformation of the valve core, reducing the degree of deformation of the water valve 200, and thus extending the service life of the water valve 200.

[0082] The position of minimum resistance can be set according to actual conditions. In the above application scenario, the position where the valve core self-blocks the second valve port 220 is the first position, and the position where the valve core blocks the third valve port 230 is the second position. The valve core, rotating from the first position to the second position, will sequentially pass through the first position, the position of minimum resistance, and the second position. The angle required for the valve core to rotate from the first position to the position of minimum resistance is the first angle, and the angle required from the position of minimum resistance to the position of minimum resistance and to the second position is the second angle. The first angle and the second angle are equal. At this time, the water flow can reach the first heat exchange object and the second heat exchange object.

[0083] In some embodiments, the method further includes:

[0084] If the rotation time of water valve 200 is greater than or equal to the third preset time, and water valve 200 has not rotated to the position of minimum resistance, control water valve 200 to stop rotating and report fault information of water valve 200.

[0085] The third preset duration can be set according to actual conditions. For example, considering factors such as aging of the water valve 200, which may cause the water valve 200 to rotate slowly and require a longer time to reach the position of minimum resistance, the third preset duration can be set to a longer value. In one example, the third preset duration can be configured as 15 seconds.

[0086] If the rotation time is greater than or equal to the third preset time, it indicates that the water valve 200 is in a faulty state, and the water valve 200 is controlled to stop rotating to save energy. In addition, the motor controller reports the fault information of the water valve 200 to the vehicle controller so that the water valve 200 can be repaired in a timely manner.

[0087] In the above application scenarios, the water valve 200 may be unable to rotate due to foreign objects, thus failing to rotate to the position of minimum resistance within a third preset time period. When the rotation time is greater than or equal to the third preset time period, the water valve 200 is controlled to stop rotating. This can prevent the water valve 200 from being squeezed by foreign objects, thereby reducing the occurrence of further damage to the water valve 200 and extending the service life of the water valve 200.

[0088] In some embodiments, before obtaining the operational requirements of the water circuit corresponding to the water valve 200, the method further includes:

[0089] When water valve 200 is in a fault state, the acquisition of the operating requirements of the water circuit corresponding to water valve 200 will be stopped, and the fault information of water valve 200 will be reported.

[0090] When the water valve 200 is in a fault-free state, the step of obtaining the operating requirements of the water circuit corresponding to the water valve 200 is executed.

[0091] A fault state refers to a state where the motor controller cannot control the valve core to rotate, while a fault state refers to a state where the motor controller can control the valve core to rotate.

[0092] In this way, if the water valve 200 malfunctions, it can be detected earlier, preventing the water valve 200 from operating in a faulty state and thus reducing the occurrence of safety accidents.

[0093] In the above application scenario, when the motor controller cannot control the valve core to rotate, the motor controller reports the fault information of water valve 200 to the vehicle controller and stops obtaining the operation status of the water circuit through the temperature sensing module.

[0094] It is worth mentioning that the water valve 200 disclosed herein may be configured as a two-way valve, a three-way valve, or a four-way valve, etc. The transmission mechanism of the water valve 200 may be transmitted through a gear mechanism and / or a linkage mechanism, but is not limited to that described above.
