[0043] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with specific embodiments and the accompanying drawings.

[0044] It should be noted that, unless otherwise defined, the technical or scientific terms used in the embodiments of this application should have the ordinary meaning understood by one of ordinary skill in the art to which this application pertains.

Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are only used to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0045] As described in the background section, during the process of adding antifreeze to the vehicle's cooling circulation lines, the engine is off, and the antifreeze in the cooling circulation lines cannot circulate, requiring multiple additions, which is time-consuming and laborious. To solve the above technical problem, related technologies include an antifreeze adding mode. In this mode, the water pump in the cooling circulation lines rotates at a preset speed, thereby allowing the antifreeze in the cooling circulation lines to circulate, allowing users or after-sales personnel to add antifreeze. However, current antifreeze adding modes do not take into account the water pump's own speed strategy. For example, the water pump in the existing vehicle's cooling circulation lines may be configured as an electric water pump. When the engine temperature is too high, even after the engine is stopped, the water pump can still rotate under electric drive, allowing the antifreeze in the cooling circulation lines to circulate and help cool the engine. The reason for excessively high engine temperature is generally due to prolonged vehicle driving time (such as 5 hours of highway driving). Upon completion of this long journey, due to the extended heat exchange, the user may need to add antifreeze. If the antifreeze adding mode is triggered directly at this time, the water pump's current rotation strategy will inevitably switch to the strategy corresponding to the antifreeze adding mode. This direct switch may affect the intended purpose of the current water pump rotation strategy, potentially impacting the vehicle's existing strategy and resulting in more harm than good. Conversely, executing the water pump rotation strategy corresponding to the antifreeze adding mode may achieve better results than the existing strategy. For example, if the current water pump rotation strategy has a duty cycle of 85%, while the antifreeze adding mode has a preset duty cycle of 60%, directly switching the current water pump rotation strategy to the antifreeze adding mode will affect engine cooling; that is, the execution of the antifreeze adding mode will negatively impact the existing cooling effect of the current water pump rotation strategy. Conversely, if the current rotation strategy of the water pump is a 60% duty cycle, while the preset duty cycle of the water pump in the corresponding antifreeze filling mode is 85%, then directly switching the current rotation strategy of the water pump to the rotation strategy corresponding to the antifreeze filling mode will benefit both engine cooling and rapid antifreeze filling. In other words, the execution of the antifreeze filling mode achieves better results than the existing strategy.

[0046] In summary, a choice needs to be made between the antifreeze filling strategy and the vehicle's existing execution strategy to avoid the antifreeze filling strategy affecting the results of the vehicle's existing strategy, and to achieve a win-win situation for both strategies.

[0047] To address the above issues, this application provides a method, device, and vehicle for adding antifreeze to a vehicle. By first obtaining the current water pump speed and the preset water pump speed corresponding to the antifreeze adding command, it determines whether to execute the antifreeze adding strategy or the vehicle's existing execution strategy, so as to cool the engine as quickly as possible and reduce the antifreeze adding time.

[0048] The present application will be further described in detail below with reference to specific embodiments and the accompanying drawings.

[0049] refer to Figure 1 This application provides a method for adding antifreeze to a vehicle. The method is applied to the vehicle's cooling circulation pipeline, which is connected to a water pump.

[0050] The method is executed by the vehicle's engine control module (ECM), and specifically includes the following steps:

[0051] S100: In response to the received antifreeze filling command, obtain the current water pump speed and the preset water pump speed corresponding to the antifreeze filling command;

[0052] In this step, in response to the received antifreeze filling command, the ECM obtains the current water pump speed and the preset water pump speed corresponding to the antifreeze filling command. The current water pump speed can be data collected by the water pump's built-in speed sensor, and the preset water pump speed can be the water pump speed specified in the antifreeze filling command. For example, if the antifreeze filling command A received by the ECM is (0x1, 60), the ECM will enter antifreeze filling mode and control the water pump to operate at a 60% duty cycle. This embodiment is mainly implemented for gasoline vehicles and hybrid vehicles. For gasoline vehicles, the ECM can directly receive the antifreeze filling command. For hybrid vehicles, the Power Distribution Control Unit (PDCU) can receive the antifreeze filling command and transmit it to the ECM, which then executes subsequent strategies.

[0053] Additionally, it should be noted that the antifreeze filling command trigger scenarios include at least the following three:

[0054] Scenario 1: The result is obtained by the user triggering the filling control on the diagnostic tool connected to the vehicle controller;

[0055] This scenario is typically an after-sales scenario, where the user is the after-sales personnel. The vehicle controller can be an ECM or PDCU. By connecting the diagnostic tool to the ECM or PDCU, the after-sales personnel can provide UDS (Unified Diagnostic Services) to the vehicle. Specifically, the diagnostic tool's interface has an antifreeze filling control that allows for user interaction. When the after-sales personnel trigger this filling control, an antifreeze filling command will be sent to the ECM or PDCU.

[0056] Scenario 2: Obtained by the user triggering the refueling control on the vehicle control interface;

[0057] This scenario typically involves users adding antifreeze themselves, but it can also be an after-sales scenario. The vehicle control interface can be the vehicle's central control screen, which has an antifreeze filling control that allows for user interaction. When the user or after-sales personnel trigger the filling control, an antifreeze filling command will be sent to the ECM or PDCU.

[0058] Scenario 3: The scenario is triggered by a preset action performed by the user; wherein the preset action is to simultaneously press the brake and accelerator pedals for a preset duration.

[0059] This scenario typically involves users adding antifreeze themselves, but it can also be an after-sales scenario. This means that the vehicle is set up with this preset action to trigger the antifreeze filling function when it is manufactured. This preset action can be any action that is not easily executed by mistake, such as pressing the brake and accelerator pedals at the same time and holding it for more than 5 seconds. More specifically, it can be pressing the brake and accelerator pedals to the bottom at the same time for more than 5 seconds. In this scenario three, due to the limitation of this preset action, it is less likely to be accidentally triggered than the situation in scenario two, where the filling control is set on the vehicle's central control screen.

[0060] S200: Based on the current water pump speed and the preset water pump speed, determine whether to execute the first antifreeze filling strategy or the second antifreeze filling strategy;

[0061] The first antifreeze filling strategy includes the process of controlling the water pump to rotate at the preset water pump speed, and the second antifreeze filling strategy includes the process of controlling the water pump to rotate at the current water pump speed.

[0062] In this step, the current water pump speed and the preset water pump speed are first judged (e.g., size judgment). Based on the judgment result, it is then determined whether to execute the preset water pump speed (i.e., the first antifreeze filling strategy) or maintain the current water pump speed (i.e., the second antifreeze filling strategy), thus enriching the existing antifreeze filling strategies.

[0063] That is, in this embodiment, after the ECM receives the antifreeze filling command, it first obtains the current water pump speed and the preset water pump speed, and selects between the first antifreeze filling strategy and the current water pump rotation strategy (i.e. the second antifreeze filling strategy) based on the current water pump speed and the preset water pump speed, instead of directly switching the existing water pump rotation strategy to the antifreeze filling strategy as described in related technologies, so as to avoid affecting the execution result of the vehicle's existing strategy due to the execution of the antifreeze filling strategy, so as to minimize the antifreeze filling time while ensuring the execution result of the vehicle's existing strategy.

[0064] In some embodiments, determining whether to execute a first antifreeze filling strategy or a second antifreeze filling strategy based on the current water pump speed and a preset water pump speed includes:

[0065] In response to determining that the current water pump speed is greater than or equal to the preset water pump speed, a second antifreeze filling strategy is executed;

[0066] In response to determining that the current water pump speed is less than the preset water pump speed, the first antifreeze filling strategy is executed.

[0067] It should be noted that, in resolving issues related to antifreeze filling, the applicant discovered that the water pump continues to run after the engine stops because of engine overheating. This means the water pump's operation due to engine overheating aims to dissipate heat as quickly as possible. Similarly, the water pump's operation for antifreeze filling aims to add antifreeze as quickly as possible. Regardless of the objective, the higher the circulation efficiency of the antifreeze in the cooling system, the better. To improve this efficiency, a higher water pump speed is preferable. Therefore, a higher water pump speed strategy can be prioritized to minimize antifreeze filling time while ensuring the vehicle's existing strategy is executed effectively.

[0068] Based on the above analysis, this embodiment illustrates an example of how the ECM selects between a first antifreeze filling strategy and a second antifreeze filling strategy based on the current water pump speed and a preset water pump speed. Specifically, when the current water pump speed is greater than or equal to the preset water pump speed (e.g., the current water pump operating speed duty cycle is 85% and the preset water pump operating speed duty cycle is 60%), the second antifreeze filling strategy is executed, i.e., maintaining the vehicle's current water pump duty cycle at 85%. When the current water pump speed is less than the preset water pump speed (e.g., the current water pump operating speed duty cycle is 60% and the preset water pump operating speed duty cycle is 85%), the first antifreeze filling strategy is executed. That is, the strategy with the higher water pump speed is prioritized to minimize the antifreeze filling time while ensuring the execution results of the vehicle's existing strategies.

[0069] In some embodiments, determining whether to implement a first antifreeze filling strategy or a second antifreeze filling strategy based on the current water pump speed and a preset water pump speed includes:

[0070] In response to determining that the current water pump speed is less than the preset water pump speed, and the difference between the current water pump speed and the preset water pump speed is less than or equal to a preset threshold, a second antifreeze filling strategy is executed.

[0071] In response to determining that the current water pump speed is less than the preset water pump speed, and the difference between the current water pump speed and the preset water pump speed is greater than the preset threshold, the first antifreeze filling strategy is executed.

[0072] This embodiment illustrates another example of how the ECM selects between a first antifreeze filling strategy and a second antifreeze filling strategy based on the current water pump speed and a preset water pump speed. Specifically, when the current water pump speed is lower than the preset water pump speed, but the difference is not significant, it is considered that the difference will not have a substantial impact on the antifreeze filling speed. Therefore, the current water pump rotation strategy can be maintained, i.e., the second antifreeze filling strategy is executed to avoid the adverse effects of frequent strategy changes on water pump operation. For example, if the preset threshold is 10%, the current water pump operating speed duty cycle is 75%, and the preset water pump operating speed duty cycle is 85%, and the difference between the two is 10%, which is less than or equal to the preset threshold, then the second antifreeze filling strategy is executed, i.e., maintaining the vehicle's current water pump duty cycle at 85%.

[0073] When the current water pump speed is lower than the preset water pump speed, but the difference is significant, it is considered that this difference will substantially affect the antifreeze filling speed. Therefore, the vehicle's current water pump rotation strategy is switched to the first antifreeze filling strategy. For example, if the preset threshold is 10%, the current water pump operating speed duty cycle is 35%, and the preset water pump operating speed duty cycle is 85%, the difference between the two is 50%, which is greater than the preset threshold. Therefore, the first antifreeze filling strategy is executed.

[0074] In this embodiment, when the current water pump speed is lower than the preset water pump speed, but the difference is not significant, it is considered that the difference will not have a substantial impact on the antifreeze filling speed, or the impact is minor. Therefore, the current water pump rotation strategy can be maintained, i.e., the second antifreeze filling strategy is executed, to avoid the adverse effects of frequent strategy changes on water pump operation. However, when the current water pump speed differs significantly from the preset water pump speed, continuing with the current water pump speed would severely affect the antifreeze filling speed. Therefore, the first antifreeze filling strategy is switched to avoid the adverse effects of excessively low water pump speed on the antifreeze filling process.

[0075] In some embodiments, reference Figure 2The method for adding antifreeze to the vehicle, provided that the current water pump speed is less than the preset water pump speed, further includes:

[0076] S300. After a preset time has elapsed since any antifreeze filling strategy was executed, the antifreeze filling amount data is obtained, and it is determined whether the antifreeze filling amount data meets the antifreeze full filling standard.

[0077] In this step, regardless of whether it is the first antifreeze filling strategy or the second antifreeze filling strategy, after executing the preset time or the preset antifreeze filling time (such as 10 minutes), it is necessary to determine whether it is full. The antifreeze filling amount data is the data that can reflect whether the antifreeze is full, and the antifreeze full filling standard is the standard that can reflect whether the antifreeze is full in the cooling circulation pipeline.

[0078] The antifreeze level data can be the overflow tank level and / or the pressure value of the cooling circulation lines. Either the overflow tank level or the cooling circulation line pressure value can be used as an indicator of whether the antifreeze is full, or both can be combined to determine the fullness. After acquiring the relevant data, the ECM can determine whether the antifreeze is full, preparing for whether to exit the current antifreeze filling strategy, maintain the current antifreeze filling strategy, or switch to a different antifreeze filling strategy.

[0079] The overflow tank's liquid level data is acquired by a level sensor installed in it. Also known as an expansion tank or filler tank, the overflow tank is connected to the cooling circulation piping. Normally, it contains antifreeze to provide redundancy, ensuring that in low-temperature environments, when the coolant volume shrinks, coolant can be drawn into the expansion tank instead of air, thus preventing air locks in the cooling system. The overflow tank typically has two lines: an upper (MAX) line and a lower (MIN) line. When the water level reaches the MIN line, it's a "replenishment reminder." Within this range, air intake in the piping is unlikely unless the ambient temperature is extremely low, causing significant contraction. However, if the water level is too close to the bottom of the tank, air may enter. Therefore, it's advisable to replenish the coolant once the MIN line is reached. Therefore, when users or after-sales personnel add antifreeze through the overflow tank, if the liquid level data of the overflow tank can remain at or above the upper limit (MAX) for a preset time (e.g., 1 minute), it means that the antifreeze in the cooling circulation pipeline is full. That is, when the antifreeze filling amount data is the overflow tank liquid level data, the corresponding antifreeze filling standard is: the liquid level data of the overflow tank can remain above the preset liquid level line for a preset time.

[0080] The pressure value of the cooling circulation pipe can be obtained by a pressure sensor installed in the cooling circulation pipe. This pressure sensor can be installed near the inlet or outlet of the cooling circulation pipe. It should be noted that the pressure value when the cooling circulation pipe is full of antifreeze varies for different vehicle models. For example, for a certain vehicle model, the pressure value when the cooling circulation pipe is full of antifreeze is 11MPa. During the antifreeze filling process, if the pressure value in the cooling circulation pipe collected by the pressure sensor can remain at 11MPa for a preset time (e.g., 1 minute), it means that the antifreeze in the cooling circulation pipe is full. That is, when the antifreeze filling data is the pressure value of the cooling circulation pipe, the corresponding standard for filling the antifreeze is: the pressure value of the cooling circulation pipe reaches the preset pressure value and remains at the preset time.

[0081] Additionally, it should be noted that the preset duration for executing the antifreeze filling strategy in this step should not be too short. This is because at the beginning of antifreeze filling, there may still be a lot of gas remaining in the cooling circulation lines. This gas needs to be discharged after the water pump has been running for a period of time. In other words, at the beginning of filling, the antifreeze may not be able to be added normally due to the gas remaining in the cooling circulation lines; for example, it may not be added at all. At this time, the antifreeze level in the overflow tank may also be too high, and the pressure value in the cooling circulation lines may also be too high. However, this "too high" or "too high" is a false indication and cannot be used as a sign that the antifreeze is full. Therefore, the antifreeze filling data should be collected only after the preset duration (e.g., more than 10 minutes) has been executed to avoid the influence of false data on subsequent strategies.

[0082] Therefore, it can be concluded that the current water pump speed should not differ too much from the preset water pump speed. If the difference is too large, there may still be a lot of gas in the cooling circulation pipeline after the antifreeze filling strategy has been executed for a preset time (such as 10 minutes), which will also affect the judgment of the antifreeze filling standard.

[0083] S400: In response to determining that the antifreeze filling data has not reached the antifreeze full filling standard, the first antifreeze filling strategy is executed;

[0084] Step S400 further includes:

[0085] In response to determining that the antifreeze filling data has not reached the antifreeze full standard, and the current antifreeze filling strategy is the first antifreeze filling strategy, the first antifreeze filling strategy is continued until the antifreeze filling data reaches the antifreeze full standard.

[0086] In response to determining that the antifreeze filling data has not reached the antifreeze full filling standard, and the current antifreeze filling strategy is the second antifreeze filling strategy, the second antifreeze filling strategy is switched to the first antifreeze filling strategy until the antifreeze filling data reaches the antifreeze full filling standard.

[0087] In this step, if the antifreeze filling standard is not reached after a certain period (e.g., 10 minutes) following the execution of an antifreeze filling strategy, further antifreeze filling is required. At this point, it's necessary to determine whether the current antifreeze filling strategy is the first or second strategy. If the current strategy is the second, it needs to switch to the first strategy. This means that if the difference between the current pump speed and the preset pump speed is considered to substantially affect the antifreeze filling speed, the first antifreeze filling strategy with the higher pump speed should be executed to achieve rapid antifreeze filling. If the current strategy is the first, it should be maintained, as this is the strategy that enables rapid antifreeze filling. The reason for not completing the filling might be due to too much antifreeze being added.

[0088] S500: In response to determining that the antifreeze filling data has reached the antifreeze full standard, the current antifreeze filling strategy is exited.

[0089] In this step, regardless of whether the first or second antifreeze filling strategy is currently being executed, as long as the antifreeze filling data reaches the antifreeze full standard after the preset time (e.g., 10 minutes), the currently executed antifreeze filling strategy can be exited and the original strategy restored.

[0090] In this embodiment, under the premise that the current water pump speed is less than the preset water pump speed, the process for determining whether the antifreeze has been fully added is further limited, and the exit time of the antifreeze adding strategy is also limited. Specifically, after executing the current antifreeze adding strategy for a period of time, the antifreeze adding data is used to determine whether it is full. If it is full, the current strategy is exited and the original strategy is restored. If it is not full, it is further determined whether the current strategy is the first antifreeze adding strategy or the second antifreeze adding strategy. If the current strategy is the first antifreeze adding strategy, the current strategy is maintained. If the current strategy is the second antifreeze adding strategy, it is switched to the first antifreeze adding strategy. That is, if it is not full after the preset adding time, the first antifreeze adding strategy with the higher water pump speed is prioritized to minimize the antifreeze adding time.

[0091] In some embodiments, the method for adding antifreeze to a vehicle further includes: after a preset time for executing any antifreeze adding strategy, exiting the current antifreeze adding strategy.

[0092] In this embodiment, another exit time for the antifreeze filling strategy is further defined. Regardless of whether the first antifreeze filling strategy or the second antifreeze filling strategy is executed, the current antifreeze filling strategy is exited after a preset duration. The preset duration can be set according to actual experience, and the preset durations for the two strategies can be different. For example, the first preset duration for executing the first antifreeze filling strategy is 15 minutes, and for another example, the first preset duration for executing the second antifreeze filling strategy is 25 minutes.

[0093] The exit strategy in this embodiment does not check whether the coolant is full or switch strategies. The strategy is simple and quick to execute. However, because it lacks a full-fill check, it only sets the filling time based on experience. This can lead to incomplete filling or wasted filling time. For example, when executing the first antifreeze filling strategy, it may complete filling in 10 minutes, but the strategy cannot be exited until 15 minutes have passed, causing the engine to run for another 5 minutes, wasting vehicle energy. Furthermore, without strategy switching, if the second antifreeze filling strategy is executed for 10 minutes, then switching back to the first strategy for 7 minutes would complete the antifreeze filling. With strategy switching, the total antifreeze filling time would be 17 minutes, but if only the second antifreeze strategy is executed, it would take 25 minutes, extending the antifreeze filling time. Users can choose different antifreeze filling exit strategies according to the actual situation of their vehicles.

[0094] In some embodiments, the method for adding antifreeze to a vehicle further includes, after receiving the antifreeze addition command:

[0095] Get vehicle status;

[0096] In response to determining that the vehicle is powered on and the gear is in park or neutral, the opening and closing status of the hood is obtained, and it is determined whether there is a fault in the water pump of the cooling circulation pipeline.

[0097] In response to determining that there is no fault information in the water pump and that the engine hood is open, the operation of starting the engine within a preset time period is performed.

[0098] In this embodiment, the preconditions for entering the antifreeze filling strategy are further defined to avoid misoperation. The vehicle information involved in these preconditions mainly includes vehicle status (including power-on status, idling status, start status, etc.), hood opening / closing status (including open and closed status), and water pump fault information (including water pump relay disconnection, water pump relay low voltage, water pump relay high voltage, water pump dry running, water pump shutdown, water pump over-temperature protection, etc.).

[0099] The specific judgment process is as follows:

[0100] (1) Determine the vehicle status. If the vehicle is powered on and the gear is in park or neutral, the vehicle will not move even if the engine is started, which can ensure the safety of personnel and is a prerequisite for adding antifreeze.

[0101] (2) Determine the open / closed state of the hood. The hood specifically refers to the front hood of the vehicle.
