Description

Technical Field

[0001] The present disclosure relates to the field of vehicle control technology, and in particular to a vehicle control method, device, electronic equipment, and vehicle. Background Art

[0002] Engine after-run means that after the vehicle is turned off, the engine controller continues to run for a period of time to request the fan to cool the cabin.

[0003] To ensure vehicle safety, the steering column lock is locked when the vehicle is turned off and locked. However, the engine is not in sleep mode due to the engine running after the vehicle is turned off, which causes the steering column lock to fail to lock successfully. Summary of the Invention

[0004] In view of this, the purpose of the present disclosure is to propose a vehicle control method, device, electronic device and vehicle to solve the current problem that when the vehicle is turned off, the engine is not in a dormant state due to the engine running afterward, which leads to the steering column lock being unable to be successfully locked.

[0005] Based on the above objectives, a first aspect of the present disclosure provides a vehicle control method, the method comprising:

[0006] Acquiring vehicle operating information, and determining a first engine water temperature corresponding to a moment when the vehicle operating information satisfies a preset operating condition;

[0007] determining a first target duty cycle based on the first engine water temperature, controlling the vehicle fan to operate for a preset time using the engine controller according to the first target duty cycle, and then controlling the engine controller to sleep, wherein the preset time is less than a time required for the steering column lock to be locked;

[0008] Determine a second engine water temperature corresponding to the sleep moment of the engine controller, determine a second target duty cycle according to the second engine water temperature, and control the vehicle fan operation using the power domain controller according to the second target duty cycle.

[0009] Based on the same inventive concept, a second aspect of the present disclosure provides a vehicle control device, comprising:

[0010] A data acquisition module is configured to acquire vehicle operating information and determine a first engine water temperature corresponding to a moment when the vehicle operating information meets a preset operating condition;

[0011] a first control module configured to determine a first target duty cycle based on the first engine water temperature, and control the engine controller to sleep after controlling the vehicle fan to operate for a preset time using the engine controller based on the first target duty cycle, wherein the preset time is less than a time required for the steering column lock to be locked;

[0012] The second control module is configured to determine a second engine water temperature corresponding to the engine controller sleep moment, determine a second target duty cycle according to the second engine water temperature, and control the vehicle fan operation using the power domain controller according to the second target duty cycle.

[0013] Based on the same inventive concept, the third aspect of the present disclosure proposes an electronic device, comprising a memory, a processor, and a computer program stored on the memory and executable by the processor, wherein the processor implements the vehicle control method as described above when executing the computer program.

[0014] Based on the same inventive concept, a fourth aspect of the present disclosure proposes a non-transitory computer-readable storage medium, which stores computer instructions for causing a computer to execute the vehicle control method as described above.

[0015] Based on the same inventive concept, the fifth aspect of the present disclosure provides a vehicle, comprising the vehicle control device described in the second aspect, the electronic device described in the third aspect, or the storage medium described in the fourth aspect.

[0016] As can be seen from the foregoing, the present disclosure provides a vehicle control method, apparatus, electronic device, and vehicle. These methods acquire vehicle operating information and determine a first engine water temperature corresponding to the moment when the vehicle operating information meets preset operating conditions. A first target duty cycle is determined based on the first engine water temperature. After the vehicle fan is controlled by an engine controller for a preset period of time based on the first target duty cycle, the engine controller is placed into hibernation. Because the preset period is shorter than the time required for the steering column lock to determine whether it is locked, the engine controller enters a hibernation state before the steering column lock determines whether it is locked, thus ensuring proper locking of the steering column lock and improving vehicle safety. A second engine water temperature corresponding to the moment when the engine controller is put into hibernation is determined. A second target duty cycle is determined based on the second engine water temperature. The vehicle fan is controlled by a power domain controller based on the second target duty cycle. Even after the engine controller is put into hibernation, the power domain controller can continue to control the vehicle fan to cool the engine compartment. Through coordinated control of the vehicle fan by the engine controller and the power domain controller, while meeting heat dissipation requirements, the problem of the steering column lock failing to lock successfully due to the engine controller being in operation can be avoided.

[0021] In order to make the objectives, technical solutions and advantages of the present disclosure more clearly understood, the present disclosure is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0022] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present disclosure should have the usual meanings understood by people with ordinary skills in the field to which the present disclosure belongs. The "first", "second" and similar words used in the embodiments of the present disclosure do not indicate any order, quantity or importance, but are only used to distinguish different components. "Include" or "comprise" and similar words mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects. "Connect" or "connected" and similar words are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative position relationships. When the absolute position of the described object changes, the relative position relationship may also change accordingly.

[0023] The terms used in this disclosure are explained as follows:

[0024] ECM: Engine Control Module (ECM), which has the function of continuously monitoring and controlling the normal operation of the engine.

[0025] PDCU: A Power Domain Control Unit (PDCU) is a hardware technology used to manage the power supply to different functional modules in electronic devices. By dividing the power domains of devices and controlling power supply, efficient system management can be achieved, improving system performance and reliability.

[0026] Engine after-run refers to the process where the engine controller continues to operate the fan for a period of time after the vehicle is turned off to cool the cabin. Existing engine after-run strategies are typically based on fixed logic designs, lacking flexibility and making it difficult to adapt to varying operating conditions.

[0027] For example, to ensure vehicle safety, the steering column lock engages when the vehicle is locked and the engine is turned off. The first time the steering column lock determines the lock is when the vehicle is locked, and the second time after a preset time has passed since power was turned off. For example, the preset time is 28 seconds, meaning the second time the steering column lock determines the lock is 28 seconds after power was turned off. Both successful locks require the ECM to be dormant. The steering column lock determines the engine status when it is locked, so the engine will not immediately go into dormancy during subsequent operation, resulting in missing the optimal locking opportunity. The above times are for illustrative purposes only and are not intended to be limiting.

[0028] Based on the above description, when the vehicle is turned off, the engine is not in a dormant state due to the engine running afterward, which leads to the problem that the steering column lock cannot be successfully locked. Therefore, this embodiment proposes a vehicle control method, such as Figure 1 As shown, the method includes:

[0029] Step 101, obtaining vehicle operating information, and determining a first engine water temperature corresponding to a moment when the vehicle operating information satisfies a preset operating condition;

[0030] Step 102, determining a first target duty cycle based on the first engine water temperature, controlling the vehicle fan to operate for a preset time using an engine controller based on the first target duty cycle, and then controlling the engine controller to sleep, wherein the preset time is less than a time required for the steering column lock to be locked;

[0031] Step 103: determine a second engine water temperature corresponding to the engine controller sleep time, determine a second target duty cycle according to the second engine water temperature, and control the vehicle fan operation using the power domain controller according to the second target duty cycle.

[0032] During specific implementation, vehicle operation information is obtained, which is the operation information of each component in the vehicle when the vehicle is running. The vehicle operation information includes at least one of the following: engine running time, battery voltage, engine water temperature, vehicle battery status and engine status, etc.

[0033] In this embodiment, vehicle operating information can be obtained in real time and compared with preset operating conditions, wherein the preset operating conditions are operating conditions corresponding to the post-operating state for determining that the vehicle enters. The post-operating state is that after the vehicle is turned off, the fan is controlled to continue running to introduce cold air with a certain wind speed, thereby reducing the ambient temperature in the cabin and protecting the components in the cabin.

[0034] If the vehicle operating information satisfies the preset operating condition, the engine water temperature at the time the vehicle operating information satisfies the preset operating condition is determined as the first engine water temperature. A first target duty cycle is determined based on the first engine water temperature, where the duty cycle is the ratio of the high-level duration of a pulse signal to the entire cycle time.

[0035] A preset duration is obtained, and the vehicle fan is controlled to operate by the engine controller according to the first target duty cycle, that is, the vehicle fan is first controlled to operate by the engine controller. When it is determined that the duration of the fan operation controlled by the engine controller reaches the preset duration, the engine controller is controlled to sleep.

[0036] In this embodiment, the vehicle fan is a device installed behind the car radiator or on the engine, and may also be called an engine fan. The vehicle fan generates wind force by rotating, forcing air to flow through the radiator or engine to accelerate heat dissipation and maintain the normal operating temperature of the engine.

[0037] Because the engine controller is dormant before the steering column lock is successfully locked, in this embodiment, the preset duration is set to be shorter than the duration required for the steering column lock to be locked. That is, the duration during which the fan is controlled by the engine controller should be shorter than the duration required for the steering column lock to be locked. In other words, the engine controller has already entered dormancy before the steering column lock is locked, thus preventing any impact on the normal locking of the steering column lock.

[0038] For example, the steering column lock determines locking for the first time when the vehicle is locked and for the second time 28 seconds after power is removed. Therefore, the predetermined time period can be set to 20 seconds. This means that the engine controller will control the vehicle fan to run for 20 seconds according to the first target duty cycle, and then control the engine controller to sleep.

[0039] An engine water temperature corresponding to the engine controller sleep time is determined as a second engine water temperature. A second target duty cycle is determined based on the second engine water temperature, and the power domain controller is used to control the vehicle fan to operate based on the second target duty cycle.

[0040] In this embodiment, the engine controller first controls the vehicle fan. After a preset duration, the engine controller is put into hibernation, and the power domain controller then controls the vehicle fan. This ensures that cooling requirements are met while preventing interference with the steering column lock, thereby improving vehicle safety.

[0041] Through the above scheme, vehicle operating information is acquired, and a first engine water temperature corresponding to the moment when the vehicle operating information meets preset operating conditions is determined. A first target duty cycle is determined based on the first engine water temperature. After the vehicle fan is controlled to operate for a preset period of time based on the first target duty cycle, the engine controller is controlled to enter a dormant state. Because the preset duration is shorter than the time required for the steering column lock to determine whether it is locked, the engine controller has already entered a dormant state before the steering column lock determines whether it is locked, which does not affect the normal locking of the steering column lock and improves vehicle safety. A second engine water temperature corresponding to the moment when the engine controller is dormant is determined, and a second target duty cycle is determined based on the second engine water temperature. The vehicle fan is controlled to operate by the power domain controller based on the second target duty cycle. After the engine controller enters a dormant state, the power domain controller can continue to control the vehicle fan to cool the engine compartment. Through the coordinated control of the vehicle fan by the engine controller and the power domain controller, while meeting heat dissipation requirements, it also avoids the problem of the steering column lock failing to lock successfully due to the engine controller being in an operating state.

[0042] In some embodiments, the vehicle operation information includes at least one of the following: engine operation time, battery voltage, engine water temperature, vehicle battery status, and engine status. The vehicle operation information in step 101 satisfies the preset operation conditions, specifically including:

[0043] Step 1011, obtaining engine running time, battery voltage, engine water temperature, vehicle battery status and engine status;

[0044] Step 1012, in response to the engine running time being greater than a first preset time threshold, the battery voltage being greater than a preset voltage threshold, the engine water temperature being greater than or equal to a first preset water temperature threshold, the engine state being a shutdown state, the vehicle battery state being a power-off state and the power-off time being less than a second preset time threshold, determines that the vehicle operating information meets the preset operating conditions.

[0045] In a specific implementation, the vehicle operation information includes at least one of the following: engine operation time, battery voltage, engine water temperature, vehicle battery status and engine status.

[0046] In this embodiment, the preset operating conditions are that the engine operating time is greater than a first preset time threshold, the battery voltage is greater than a preset voltage threshold, the engine water temperature is greater than or equal to a first preset water temperature threshold, the engine state is a shutdown state, the vehicle battery state is a power-off state and the power-off time is less than a second preset time threshold.

[0047] That is, the vehicle operation information is compared with the preset operation conditions to determine whether each parameter information in the vehicle operation information meets the parameter conditions shown in the preset operation conditions.

[0048] For example, the first preset time threshold is 10 minutes, the preset voltage threshold is 11.5V, the first preset water temperature threshold is 105 degrees Celsius, and the second preset time threshold is 10 seconds. That is, the preset operating conditions are that the engine has been running for more than 10 minutes, the battery voltage is greater than 11.5V, the engine water temperature is greater than or equal to 105 degrees Celsius, the engine is in a stopped state, and the vehicle battery is in a powered-off state and the powered-off time is less than 10 seconds.

[0049] In this embodiment, the engine running time being greater than the first preset time threshold value refers to the engine running time being greater than the first preset time threshold value in one driving cycle, rather than the cumulative value of the engine running time in several driving cycles.

[0050] Through the above solution, by setting the engine running time to be greater than the first preset time threshold, it is ensured that the engine has been fully preheated, so that the various components inside the engine reach a temperature suitable for operation, thereby avoiding the subsequent use of the engine controller to control the fan operation and reducing part wear. By setting the battery voltage to be greater than the preset voltage threshold, it is ensured that the subsequent control of the fan operation will not cause the battery to run low, thereby avoiding affecting the normal use of the vehicle by subsequent users. By setting the engine water temperature to be greater than or equal to the first preset water temperature threshold, the first preset water temperature threshold can be set to the temperature corresponding to the cooling point. If the engine water temperature is less than the temperature corresponding to the cooling point, it means that the engine water temperature is low and there is no need to continue cooling through the fan, thus avoiding useless heat dissipation actions and reducing the loss of vehicle power.

[0051] In some embodiments, determining a first target duty cycle according to the first engine water temperature in step 102 specifically includes:

[0052] Step 1021, searching a first corresponding relationship of an engine controller according to the first engine water temperature, and determining a first duty cycle corresponding to the first engine water temperature;

[0053] Step 1022: searching for a second corresponding relationship corresponding to the power domain controller according to the first engine water temperature, and determining a second duty cycle corresponding to the first engine water temperature;

[0054] Step 1023 : Compare the first duty cycle and the second duty cycle, and take the maximum value of the first duty cycle and the second duty cycle as a first target duty cycle.

[0055] During specific implementation, the first corresponding relationship corresponding to the engine controller is searched according to the first engine water temperature, and the first duty cycle corresponding to the first engine water temperature is determined, wherein the first corresponding relationship is the corresponding relationship between the engine water temperature corresponding to the engine controller and the duty cycle, and the form of the first corresponding relationship includes at least one of the following: a relationship table, a function relationship, a curve relationship, a key-value pair relationship and a bar chart relationship.

[0056] For example, the first corresponding relationship of the engine controller is as follows: if the engine water temperature is greater than or equal to 105 degrees Celsius and less than 115 degrees Celsius, the vehicle fan duty cycle is determined to be 30%. If the engine water temperature is greater than 115 degrees Celsius, the vehicle fan duty cycle is determined to be 60%.

[0057] Specifically, the vehicle fan duty cycle refers to the ratio of the duration of the high level in the vehicle fan pulse signal to the entire cycle. When the fan pulse signal is high, the fan is on and operating. When the fan pulse signal is low, the fan is off and inactive. Therefore, the higher the engine water temperature, the longer the vehicle fan operates to lower it, and the correspondingly higher the vehicle fan duty cycle.

[0058] According to the first engine water temperature, a second corresponding relationship corresponding to the power domain controller is searched to determine a second duty cycle corresponding to the first engine water temperature, wherein the second corresponding relationship is a corresponding relationship between the engine water temperature corresponding to the power domain controller and the duty cycle, and the form of the second corresponding relationship includes at least one of the following: a relationship table, a function relationship, a curve relationship, a key-value pair relationship and a bar chart relationship.

[0059] For example, the second corresponding relationship corresponding to the power domain controller is as follows: if the engine water temperature is greater than or equal to 105 degrees Celsius and less than 115 degrees Celsius, the vehicle fan duty cycle is determined to be 35%. If the engine water temperature is greater than 115 degrees Celsius, the vehicle fan duty cycle is determined to be 55%. If the engine water temperature is less than 115 degrees Celsius, the vehicle fan duty cycle is determined to be 10%.

[0060] The determined first duty cycle is compared with the second duty cycle, and a maximum value of the first duty cycle and the second duty cycle is determined as a first target duty cycle.

[0061] For example, if the first engine water temperature is determined to be 110 degrees Celsius, a first duty cycle is determined to be 30% based on a first correspondence relationship corresponding to the engine controller, and a second duty cycle is determined to be 35% based on a second correspondence relationship corresponding to the power domain controller. The first and second duty cycles are compared to determine a first target duty cycle of 35%.

[0062] Through the above scheme, by comparing the first duty cycle corresponding to the engine controller with the second duty cycle corresponding to the power domain controller, the larger value of the two is taken as the final first target duty cycle, and then the vehicle fan operation is controlled according to the first target duty cycle. By controlling with a higher duty cycle, the control speed of the vehicle fan is improved, and the heat dissipation efficiency of the vehicle engine compartment is improved.

[0063] In some embodiments, controlling the operation of the vehicle fan using the power domain controller according to the second target duty cycle in step 103 specifically includes:

[0064] Step 1031: determining a total control duration corresponding to the second duty cycle according to the second duty cycle;

[0065] Step 1032: Subtract the total control duration from the preset duration to obtain a first duration.

[0066] Step 1033: Based on the second target duty cycle, use the power domain controller to control the vehicle fan to run for the first duration.

[0067] In specific implementation, the second engine water temperature corresponding to the sleep moment of the engine controller is determined, the second corresponding relationship corresponding to the power domain controller is searched according to the second engine water temperature, and the second target duty cycle corresponding to the second engine water temperature is determined.

[0068] In this embodiment, the vehicle fan is a fan controlled by a power domain controller.

[0069] A second correspondence relationship corresponding to the power domain controller is searched based on the first engine water temperature to determine a second duty cycle corresponding to the first engine water temperature. A database is searched based on the second duty cycle to determine a total control duration corresponding to the second duty cycle, wherein the database stores a third correspondence relationship between the duty cycle and the control duration, wherein the third correspondence relationship is in the form of at least one of the following: a relationship table, a function relationship, a curve relationship, a key-value pair relationship, and a bar graph relationship.

[0070] For example, the third corresponding relationship between the duty cycle and the control duration is as follows: if the duty cycle of the vehicle fan is 30%, the control duration is 30 seconds; if the duty cycle of the vehicle fan is 55%, the control duration is 60 seconds.

[0071] The total control duration is subtracted from the preset duration to obtain a first duration. According to the second target duty cycle, the power domain controller is used to control the vehicle fan to operate for the first duration.

[0072] For example, the second engine water temperature corresponding to the moment the engine controller is dormant is determined to be 110 degrees Celsius. A second correspondence is searched to determine that the second target duty cycle corresponding to the second engine water temperature is 35%. The first engine water temperature corresponding to the moment the vehicle operating information meets the preset operating conditions is determined to be 120 degrees Celsius. Based on the first engine water temperature, a second correspondence is searched to determine that the second duty cycle corresponding to the first engine water temperature is 55%. The total control duration corresponding to the second duty cycle is determined to be 60 seconds. If the preset duration is 20 seconds, the first duration is 40 seconds. That is, based on the second target duty cycle of 35%, the power domain controller is used to control the vehicle fan to operate for 40 seconds.

[0073] Through the above scheme, since the vehicle fan is the main control fan of the power domain controller, the second duty cycle is first determined based on the first engine water temperature corresponding to the moment when the vehicle operating information meets the preset operating conditions, and then the total control time corresponding to the second duty cycle is determined based on the second duty cycle. The total control time is determined more accurately, avoiding the problem of poor heat dissipation effect caused by too short control time of the vehicle fan, and at the same time avoiding excessive consumption of vehicle battery power due to too long control time of the vehicle fan, resulting in the risk of insufficient power when subsequent users use the vehicle.

[0074] In some embodiments, when obtaining vehicle operating information and determining that the vehicle operating information satisfies a first engine water temperature corresponding to a preset operating condition, the preset operating condition may be double-judged by the engine controller and the power domain controller, that is, step 101 specifically includes:

[0075] Step 101A, obtaining vehicle operation information, and judging the vehicle operation information through the engine controller and the power domain controller respectively;

[0076] Step 101B: In response to the engine controller and the power domain controller both determining that the vehicle operating information meets a preset operating condition, determine a first engine water temperature.

[0077] During specific implementation, the vehicle operation information is obtained, and the vehicle operation information is judged by the engine controller while the vehicle operation information is judged by the power domain controller.

[0078] If both the engine controller and the power domain controller determine that the vehicle operating information meets the preset operating conditions, then it is determined that the vehicle operating information meets the preset operating conditions, and then the first engine water temperature at the current moment is determined.

[0079] Exemplarily, the preset operating conditions are that the engine operating time is greater than a first preset time threshold, the battery voltage is greater than a preset voltage threshold, the engine water temperature is greater than or equal to a first preset water temperature threshold, the engine state is a shutdown state, the vehicle battery state is a power-off state and the power-off time is less than a second preset time threshold.

[0080] Obtain vehicle operating information. If the engine controller determines that the engine has been running for more than 10 minutes, the battery voltage is greater than 11.5V, the engine water temperature is greater than or equal to 105 degrees Celsius, the engine is in a stopped state, and the vehicle battery is in a powered-off state with a power-off duration of less than 10 seconds. Furthermore, if the power domain controller determines that the engine has been running for more than 10 minutes, the battery voltage is greater than 11.5V, the engine water temperature is greater than or equal to 105 degrees Celsius, the engine is in a stopped state, and the vehicle battery is in a powered-off state with a power-off duration of less than 10 seconds, both judgments are passed, and it can be determined that the vehicle operating information meets the preset operating conditions, and the first engine water temperature at the current moment is determined.

[0081] Through the above solution, the vehicle operation information is double-judged by the engine controller and the power domain controller. Only when the engine controller and the power domain controller both determine that the vehicle operation information meets the preset operating conditions can the first engine water temperature be subsequently obtained, thereby avoiding relying solely on the engine controller or solely on the power domain controller for judgment, and avoiding erroneous control operation of the vehicle fan due to erroneous judgment, resulting in unnecessary energy consumption and waste.

[0082] In some embodiments, after the power domain controller is used to control the vehicle fan to operate, the problem of excessive engine water temperature may still exist. In this case, to avoid the problem that the engine water temperature is too high and the vehicle is in a hot static state, which affects the life of the vehicle, the vehicle fan needs to be controlled again. That is, after step 103, the following steps are also included:

[0083] Step 10A, determining a third engine water temperature after the vehicle fan is controlled to operate by the power domain controller according to the second target duty cycle;

[0084] Step 10B, in response to the third engine water temperature being greater than or equal to a first preset water temperature threshold, determining a target controller based on the third engine water temperature, and using the target controller to control the vehicle fan to operate until the engine water temperature is less than the first preset water temperature threshold.

[0085] In a specific implementation, after the vehicle fan is controlled to operate for the first duration by the power domain controller according to the second target duty cycle, the vehicle fan operation time reaches the total control duration corresponding to the second duty cycle. The engine water temperature at this time is determined as the third engine water temperature.

[0086] The third engine water temperature is compared with a first preset water temperature threshold, wherein the first preset water temperature threshold is a temperature corresponding to a cooling point.

[0087] If the third engine water temperature is greater than the first preset water temperature threshold, this indicates that after the total duration of the vehicle fan operation controlled by the engine controller and the power domain controller, the engine water temperature is still higher than the temperature corresponding to the cooling point. This indicates that the vehicle is still at risk of thermal standstill. In this case, the target controller is determined based on the third engine water temperature, where the target controller is either the engine controller or the power domain controller.

[0088] The target controller is used to control the vehicle fan to operate until the engine water temperature is lower than the first preset water temperature threshold.

[0089] In some embodiments, determining a target controller according to the third engine water temperature specifically includes:

[0090] Step A: in response to the third engine water temperature being greater than or equal to a first preset water temperature threshold and less than a second preset water temperature threshold, determining that the target controller is a power domain controller, determining a third target duty cycle based on the third engine water temperature, and controlling the operation of the vehicle fan using the power domain controller based on the third target duty cycle;

[0091] Step B, in response to the third engine water temperature being greater than or equal to the second preset water temperature threshold, determining that the target controller is the engine controller, sending a wake-up command to the engine controller, determining a fourth target duty cycle based on the third engine water temperature, and controlling the vehicle fan operation using the engine controller based on the fourth target duty cycle.

[0092] In specific implementation, if the third engine water temperature is greater than or equal to the first preset water temperature threshold and less than the second preset water temperature threshold, it means that although the engine water temperature at this time is higher than the temperature of the cooling point, the excess is small, and low-voltage control can be performed only by relying on the power domain controller.

[0093] Therefore, when the third engine water temperature is greater than or equal to the first preset water temperature threshold and less than the second preset water temperature threshold, the target controller is determined to be the power domain controller. Based on the third engine water temperature, the second corresponding relationship corresponding to the power domain controller is searched, and a third target duty cycle corresponding to the third engine water temperature is determined. The vehicle fan is then controlled using the power domain controller based on the third target duty cycle.

[0094] For example, if the first preset water temperature threshold is 105 degrees Celsius and the second preset water temperature threshold is 115 degrees Celsius, and if the third engine water temperature is determined to be 108 degrees Celsius, the target controller is determined to be the power domain controller. A third target duty cycle corresponding to the third engine water temperature is found to be 25%, and the power domain controller is used to control the vehicle fan according to the third target duty cycle.

[0095] If the third engine water temperature is greater than or equal to the second preset water temperature threshold, it means that the engine water temperature at this time is much higher than the temperature of the cooling point, and relying solely on the power domain controller for low-pressure control may not be sufficient to reduce the engine water temperature to below the first preset water temperature threshold.

[0096] Therefore, when the third engine water temperature is greater than or equal to the second preset water temperature threshold, the target controller is determined to be the engine controller, and a wake-up instruction is sent to the engine controller to wake up the engine controller. A first correspondence relationship corresponding to the engine controller is searched based on the third engine water temperature, and a fourth target duty cycle corresponding to the third engine water temperature is determined. The vehicle fan is then controlled using the engine controller based on the fourth target duty cycle.

[0097] For example, if the first preset water temperature threshold is 105 degrees Celsius and the second preset water temperature threshold is 115 degrees Celsius, and if the third engine water temperature is determined to be 125 degrees Celsius, the target controller is determined to be the engine controller. A fourth target duty cycle corresponding to the third engine water temperature is found to be 60%, and the engine controller is used to control the vehicle fan according to the fourth target duty cycle.

[0098] Through the above solution, even after the power domain controller is used to control the vehicle fan, if the engine water temperature may still be too high, the vehicle fan needs to be controlled again to avoid the problem of excessive engine water temperature causing the vehicle to be in a hot idle state and affecting the vehicle's lifespan.
