[0047] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0048] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0049] The main solution of the embodiment of the present application is: during the driving process of the vehicle, the ambient temperature and the current position are obtained; the current section of the vehicle is determined according to the current position; the target operating state of the variable air intake grille, thermostat, water pump and fan is determined according to the current section of the vehicle and the ambient temperature; and the vehicle cooling is controlled according to the target operating state.

[0050] In the prior art, fans and water pumps are controlled based only on the distribution of water temperature (or IGBT temperature) and vehicle speed. On-site power generation is controlled based on the distribution of water temperature / vehicle speed, or the water pump and fan are made to run at full speed from the beginning like GPF on-site regeneration. It is impossible to flexibly adjust the cooling components according to the working conditions of the vehicle.

[0051] This application provides a solution, which uses the vehicle's built-in GPS positioning function to identify the starting point of a specified special bad road section, and when the ambient temperature is high, improve the operation of the cooling system, reduce the initial oil and water temperature before climbing, and absorb the temperature rise during the climbing process. For special bad road sections that have not been identified, the possible new ramps are identified through the analysis of the slope and throttle opening, and the operation of the cooling system is improved in advance to reduce the initial oil and water temperature before climbing and absorb the temperature rise during the climbing process.

[0052] It should be noted that the execution subject of this embodiment may be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device capable of realizing the above functions, a controller inside a vehicle, etc. The following takes the controller inside a vehicle as an example to illustrate this embodiment and the following embodiments.

[0053] Based on this, the embodiment of the present application provides a vehicle cooling control method, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the vehicle cooling control method of the present application.

[0054] In this embodiment, the vehicle cooling control method is applied to a vehicle, in which a variable air intake grille, a thermostat, a water pump and a fan are provided;

[0055] It should be noted that the variable air intake grille, thermostat, water pump and fan installed in the vehicle together constitute the vehicle's cooling system.

[0056] The variable grille can be an AGS (Active Grille Shutter) system. The variable grille mainly controls the air flow in the engine compartment to improve fuel efficiency and performance while reducing emissions. The specific scenarios are as follows:

[0057] Closed state: When the vehicle is driving at low speed or cold start, the AGS system will close the grille shutters to reduce the amount of air entering the engine compartment. This helps speed up the engine warm-up process, reduce heat loss, and improve fuel efficiency.

[0058] Open state: When the vehicle is traveling at high speed or the engine requires more cooling, the AGS system will open the grille shutters to increase the amount of air entering the engine compartment to provide better cooling effect.

[0059] The main function of the thermostat is to control the flow of engine coolant to maintain the engine running within the optimal operating temperature range.

[0060] The main function of the water pump is to circulate the coolant to ensure that the engine runs within the optimal operating temperature range. The main function of the fan is to help the radiator dissipate heat effectively and ensure that the engine runs within the optimal operating temperature range. The fan usually works in conjunction with the thermostat. When the engine temperature rises to a certain value, the thermostat opens, the coolant flows through the radiator, and the fan starts to help the radiator dissipate heat.

[0061] In this embodiment, the vehicle cooling control method includes steps S10 to S40:

[0062] Step S10: Acquire the ambient temperature and current position of the vehicle while the vehicle is traveling.

[0063] It should be noted that during the driving process of the vehicle, if the vehicle is in different environments, the required cooling requirements will also be different. Therefore, the ambient temperature and the current position of the vehicle can be obtained in real time. The ambient temperature can be detected by the temperature sensor, and the current position can be detected using the vehicle's built-in GPS positioning function.

[0064] Step S20: Determine the road section where the vehicle is currently located according to the current position.

[0065] It should be noted that the location information of different road sections can be collected in advance, and the road sections can be divided according to the conditions of the road sections, so as to divide each road section into special bad road sections and non-special bad road sections. Special bad road sections can be mountainous areas, high altitude road sections or road sections with large slopes, etc. Non-special bad road sections can be ordinary roads. A database for road section division is established, which includes the types of each road section and the corresponding location information.

[0066] After determining the current position, the database can be queried according to the current position to obtain the road section where the current position is located. The road section where the vehicle is currently located can be a preset road section, that is, a special bad road section. The road section where the vehicle is currently located can also not be a preset road section, that is, a non-special bad road section.

[0067] Step S30: determining the target operating states of the variable air intake grille, the thermostat, the water pump, and the fan according to the current road section of the vehicle and the ambient temperature.

[0068] It should be understood that the target operating state of the variable air intake grille, thermostat, water pump and fan in the cooling system can be determined according to the current road section and ambient temperature of the vehicle. Under different ambient temperatures and different road sections, the target operating states of the variable air intake grille, thermostat, water pump and fan are different, so the operating states of the variable air intake grille, thermostat, water pump and fan can be flexibly adjusted according to the actual working conditions of the vehicle.

[0069] The target operating states include: fully open state, fully closed state, and any state between the fully open state and the fully closed state, which can be set according to the working conditions.

[0070] Step S40: Perform vehicle cooling control according to the target operating state.

[0071] In a specific implementation, after the target operating state of each component in the cooling system is determined, the vehicle can be cooled and controlled according to the target operating state.

[0072] In a feasible implementation, step S40 may include step S41:

[0073] Step S41: Controlling the variable air intake grille, the thermostat, the water pump and the fan to operate according to the target operating state to perform cooling control on the vehicle.

[0074] It should be understood that after determining the target operating state, the target operating state of the variable air intake grille, the target operating state of the thermostat, the target operating state of the water pump and the target operating state of the fan can be specifically obtained, so that each component can be controlled to operate according to the target operating state, thereby achieving vehicle cooling control.

[0075] Specifically, for example, the target operating state of the variable air intake grille is fully open, the target operating state of the thermostat is fully open, the target operating state of the water pump is 80% open, and the target operating state of the fan is 90% open. The variable air intake grille, thermostat, water pump and fan can be controlled according to the above target operating states to cool the vehicle.

[0076] This embodiment provides a vehicle cooling control method, in which a variable air intake grille, a thermostat, a water pump and a fan are provided in the vehicle, and the method comprises: obtaining the ambient temperature and the current position of the vehicle during driving; determining the current road section of the vehicle according to the current position; determining the target operating state of the variable air intake grille, the thermostat, the water pump and the fan according to the current road section of the vehicle and the ambient temperature; and performing vehicle cooling control according to the target operating state. The vehicle's own positioning function is used to identify the starting point of a specified special road section, and the operating state of each device in the vehicle is controlled and adjusted according to the ambient temperature to improve the vehicle cooling effect.

[0077] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the above-mentioned embodiment 1 can be referred to the above introduction, and will not be repeated in the following. Figure 2 , step S30 includes steps S301 to S303:

[0078] Step S301: Determine the reference operating states of the variable air intake grille, the thermostat, the water pump, and the fan according to the current road section of the vehicle and the ambient temperature.

[0079] It is understandable that the reference operating state is determined based on the current road section of the vehicle and the ambient temperature, and the reference operating state does not necessarily represent the final operating state of each component in the cooling system.

[0080] Specifically, it can determine whether the current road section of the vehicle is a preset road section and whether the ambient temperature is higher than the set temperature threshold, and jointly determine the reference operating state of each component according to different road sections and ambient temperature conditions.

[0081] When the vehicle's current road section and / or ambient temperature are different, the corresponding reference operating states of the variable air intake grille, thermostat, water pump, and fan are also different.

[0082] Step S302: Obtaining preset operating states of the variable air intake grille, thermostat, water pump and fan calculated based on vehicle operating data.

[0083] In specific implementation, the vehicle operation data may include water temperature, vehicle speed and other data. The operation status of each component of the current cooling system can be calculated based on the water temperature, vehicle speed and other data, but it may not be flexibly adjusted. The preset operation status of the variable air intake grille, thermostat, water pump and fan calculated based on the vehicle operation data may be: when the engine coolant temperature is lower than a certain threshold (such as 70°C), the thermostat remains closed to accelerate the engine warm-up; the water pump runs at a lower speed; when starting at low temperature or driving at low speed (such as speed less than 30km / h), AGS is closed to reduce air resistance and speed up the warm-up process. When the engine temperature rises (such as exceeding 85°C) or when driving at high speed (such as speed greater than 60km / h), AGS is turned on to enhance the heat dissipation effect. When the coolant temperature is low (such as below 90°C), the fan remains closed.

[0084] Step S303: determining target operating states of the variable air intake grille, the thermostat, the water pump, and the fan according to the reference operating state and the preset operating state.

[0085] In a specific implementation, after the preset operating state and the reference operating state are determined, the target operating state of the variable air intake grille, the thermostat, the water pump and the fan can be determined by combining the reference operating state and the preset operating state.

[0086] Specifically, the preset operating state and the reference operating state can be coordinated and the larger one can be taken, and the finally determined operating state can be used as the target operating state. For example, if the preset operating state of the variable air intake grille is fully open and the reference operating state is half open, then the target operating state of the variable air intake grille is fully open. For example, if the reference operating state of the fan is 50% open and the preset operating state is 30% open, then the target operating state of the fan is 50% open.

[0087] This embodiment determines the reference operating state of the variable air intake grille, the thermostat, the water pump and the fan according to the current road section of the vehicle and the ambient temperature; obtains the preset operating state of the variable air intake grille, the thermostat, the water pump and the fan calculated according to the vehicle operation data; and determines the target operating state of the variable air intake grille, the thermostat, the water pump and the fan according to the reference operating state and the preset operating state. By obtaining the preset operating state calculated by the vehicle operation data and determining the target operating state of each component in combination with the reference operating state, the operation of each component in the cooling system can be controlled more accurately, thereby improving the cooling effect of the vehicle.

[0088] Based on the first and second embodiments of the present application, in the third embodiment of the present application, the same or similar contents as those in the first embodiment can be referred to the above description, and will not be described in detail later. Figure 3, step S301 includes steps A11 to A12:

[0089] Step A11: When the current road section of the vehicle is not a preset road section, the current throttle opening and the current slope are obtained.

[0090] It should be noted that the preset road section is set as a special harsh road section in this embodiment. If the vehicle is currently on a road section that is not a special harsh road section, the possible new ramp can be identified by analyzing information such as slope and throttle opening, so as to perform corresponding control.

[0091] In a specific implementation, the current throttle opening can be acquired through a sensor provided on the vehicle, for example, through an electronic throttle pedal sensor; the current slope can be acquired through a three-axis acceleration sensor.

[0092] Step A12: Determine the reference operating states of the variable air intake grille, the thermostat, the water pump and the fan according to the current throttle opening, the current slope and the ambient temperature.

[0093] It is understandable that the operating state of the variable air intake grille, thermostat, water pump and fan under the current working condition can be determined based on the current throttle opening, the current slope and the ambient temperature.

[0094] In a feasible implementation, step A12 may include: when the ambient temperature is greater than a preset temperature threshold, the current slope is greater than a preset slope threshold, and the throttle opening is greater than a preset throttle opening threshold and the maintenance time is greater than a preset time, determining that the reference operating states of the variable air intake grille, the thermostat, the water pump, and the fan are all fully open.

[0095] It should be noted that the preset temperature threshold, preset slope threshold, preset throttle opening threshold and preset time can be set in advance. For example, the preset temperature threshold is set to greater than 30 degrees Celsius, the preset slope threshold is set to 3%, the preset throttle opening threshold is set to 30%, and the preset time can be set to 5s. By comparing the ambient temperature with the preset temperature threshold, comparing the current slope with the preset slope threshold, and comparing the throttle opening with the preset throttle opening threshold, the reference operating state under different conditions is determined.

[0096] In a specific implementation, when the ambient temperature is greater than a preset temperature threshold of 30 degrees Celsius, the current slope condition can be further judged. If the current slope is greater than the preset slope threshold of 3%, the throttle opening condition is further judged. If the throttle opening is greater than the preset throttle opening threshold by 30% and the throttle opening is greater than the preset throttle opening threshold for a period of time greater than the preset time of 5s, the gear position of the variable air intake grille is adjusted to the maximum, that is, the fully open state; the thermostat is adjusted to the fully open state; the electronic water pump is adjusted to the fully open state, and the fan gear is adjusted to 100% open, and the above state is used as the reference operating state of each component.

[0097] It is understandable that the ambient temperature, current slope, and throttle opening may not exceed the threshold. Therefore, in a feasible implementation, step A12 may also include: when any one of the ambient temperature is less than or equal to the preset temperature threshold, the current slope is less than or equal to the preset slope threshold, the throttle opening is less than or equal to the preset throttle opening threshold and the maintenance time is less than or equal to the preset time, determining that the reference operating states of the variable air intake grille, the thermostat, the water pump, and the fan are all fully closed.

[0098] In a specific implementation, if one or more of the following conditions is met: the ambient temperature is lower than the preset temperature threshold, the current slope is lower than or equal to the preset slope threshold, the throttle opening is lower than or equal to the preset throttle opening threshold and the maintenance time does not reach 5s, each component in the cooling system can be directly set to a fully closed state.

[0099] It should be understood that if the ambient temperature is less than or equal to the preset temperature threshold, each component in the cooling system is directly set to a fully closed state, and this is used as a reference operating state of each component.

[0100] In this embodiment, when the vehicle is currently on a road section that is not a preset road section, the current throttle opening and the current slope are obtained; the reference operating states of the variable air intake grille, the thermostat, the water pump, and the fan are determined based on the current throttle opening, the current slope, and the ambient temperature; for unrecognized road sections, new ramps can be identified by analyzing the slope and throttle opening, thereby controlling the operating states of various components in the cooling system and improving the control effects on the variable air intake grille, the thermostat, the water pump, and the fan.

[0101] Based on the first and second embodiments of the present application, in the fourth embodiment of the present application, the same or similar contents as those in the first embodiment can be referred to the above description, and will not be described in detail later. Figure 4 , step S301 includes steps B11 to B12:

[0102] Step B11: When the road section currently located by the vehicle is a preset road section, a mapping relationship table is queried according to the current position and the ambient temperature.

[0103] It should be noted that when the vehicle is currently on a preset section, proving that the vehicle is in some designated special harsh sections, the mapping relationship table can be queried according to the current position and ambient temperature. The mapping relationship table is a mapping relationship between the designated section-ambient temperature and the operating status of each component.

[0104] As shown in Table 1, Table 1 is a mapping relationship table between a specified road section-ambient temperature and each device.

[0105] Table 1

[0106]

[0107] Step B12: Determine the reference operating states of the variable air intake grille, the thermostat, the water pump, and the fan corresponding to the current position and the ambient temperature in the mapping relationship table.

[0108] In the specific implementation, the road identification start-end point is a special bad road section collected in advance in multiple different regions. For example, if the ambient temperature is greater than 35 degrees and less than 40 degrees, and the current road section is section C, then the corresponding AGS gear is fully open, the thermostat is fully open, the water pump is turned on 80%, and the fan is 80%. Under different road sections and different ambient temperatures, the corresponding reference operating states of the variable air intake grille, thermostat, water pump, and fan are different. The corresponding reference operating state can be quickly queried according to Table 1 above, which improves the flexibility of parameter determination during vehicle cooling control.

[0109] In this embodiment, when the current road section of the vehicle is a preset road section, a mapping relationship table is queried according to the current position and the ambient temperature; the reference operating states of the variable air intake grille, the thermostat, the water pump, and the fan corresponding to the current position and the ambient temperature are determined in the mapping relationship table. The reference operating states of the variable air intake grille, the thermostat, the water pump, and the fan can be quickly queried through the mapping relationship table established in advance, thereby improving the flexibility of parameter determination during vehicle cooling control.

[0110] For example, in order to help understand the implementation process of the vehicle cooling control method obtained by combining this embodiment with the above-mentioned embodiment 1, please refer to Figure 5 , Figure 5A brief flow chart of a vehicle cooling control method is provided, specifically: obtaining an ambient temperature signal and a GPS position signal, determining the current section of the vehicle according to the position signal, and if the current section of the vehicle is a preset designated section, querying a MAP table according to the ambient temperature and the current section of the vehicle to obtain the gear state quantity of the AGS / thermostat / water pump / fan; if the current section of the vehicle is not a preset designated section, obtaining a throttle opening signal and a slope signal to determine whether the ambient temperature is greater than 3 0 degrees Celsius, if not, AGS / thermostat / water pump / fan are all off; when the ambient temperature is greater than 30 degrees Celsius, check whether the slope is greater than 3%, if not, AGS / thermostat / water pump / fan are all off; if the slope is greater than 3%, determine whether the throttle opening is greater than 30% and the maintenance time is greater than 5 seconds, if not, AGS / thermostat / water pump / fan are all off; if the throttle opening is greater than 30% and the maintenance time is greater than 5 seconds, AGS gear is maximum / thermostat is maximum / electronic water pump is maximum / fan is maximum. The preset state quantity of the thermostat, water pump, AGS and fan gear calculated according to the water temperature, vehicle speed, etc. and the reference state quantity are coordinated and taken as the larger one, so as to control the execution of AGS, thermostat, water pump and fan.

[0111] It should be noted that the above examples are only used to understand the present application and do not constitute a limitation on the vehicle cooling control method of the present application. More simple transformations based on this technical concept are all within the protection scope of the present application.

[0112] This application also provides a vehicle cooling control device, please refer to Figure 6 , the vehicle cooling control device comprises:

[0113] The acquisition module 10 is used to acquire the ambient temperature and the current position of the vehicle during driving.

[0114] The determination module 20 is used to determine the road section where the vehicle is currently located according to the current position.

[0115] The determination module 20 is further used to determine the target operating state of the variable air intake grille, the thermostat, the water pump and the fan according to the current road section of the vehicle and the ambient temperature.

[0116] The control module 30 is used to perform vehicle cooling control according to the target operating state.

[0117] The vehicle cooling control device provided by the present application adopts the vehicle cooling control method in the above embodiment, which can solve the technical problem that the current vehicle cooling control cannot be flexibly adjusted according to the working conditions of the vehicle, resulting in poor cooling control effect.
