[0046] The embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0047] A vehicle thermal management execution method is provided in one or more embodiments of the present application, which is applied to a vehicle thermal management system.

[0048] Here, the execution mode of the vehicle thermal management system includes a low-power consumption operation mode and a non-low-power consumption operation mode. The thermal management system includes thermal management components that need to be cooled, such as motor-related components or battery components, etc. For the above-mentioned thermal management system, the way to cool the motor-related components or battery components can be through a fan or through a cooling liquid circulation loop, which will not be described in detail in the present application.

[0049] As shown in Figure 1 and Figure 2 In some embodiments, the vehicle thermal management execution method described in the present application includes:

[0050] S101, obtaining the predicted driving time of the vehicle.

[0051] Here, in some embodiments, in step S101, it includes:

[0052] S1011, obtaining the current driving scene information of the vehicle, the driving scene information including high-speed driving scene information and non-high-speed driving scene information.

[0053] S1012, in response to determining that the vehicle is currently in the non-high-speed driving scene information, obtaining the predicted driving time of the vehicle.

[0054] In some embodiments, in the steps S1011 and S1012, the high-speed driving scene information refers to that the vehicle is driving on a highway, and the non-high-speed driving scene information refers to that the vehicle is not driving on a highway. The way that the vehicle head unit obtains the current driving scene information of the vehicle can be to obtain the position of the vehicle by navigation (such as GPS, Beidou satellite positioning), and when the obtained position of the vehicle is on the highway, it is determined that the vehicle is currently in the high-speed driving scene. At this time, due to the influence of the vehicle speed factor on the highway, the vehicle thermal management component is warmed up faster, and the low-power operation of the thermal management system will cause the temperature control of the thermal management component to be unstable, which will cause a safety hazard. Therefore, only when the obtained position of the vehicle is in the non-high-speed driving scene information, that is, the vehicle is not on the highway, the subsequent steps of the application are continued.

[0055] In addition, in step S101, it also includes:

[0056] S1013, determining the estimated driving distance of the vehicle according to the distance between the current position of the vehicle and the destination.

[0057] S1014, determining the estimated driving time of the vehicle according to the driving road condition and the estimated driving distance, wherein the driving road condition includes traffic light information and traffic condition information.

[0058] In some embodiments, the estimated driving distance in the above steps can be obtained by determining the distance between the current position of the vehicle and the destination by navigation. The traffic condition information includes the traffic congestion state on the current driving road obtained by navigation. For example, the time for passing through the congested road section is estimated according to the severity of the traffic congestion, and the total estimated driving time of the vehicle is obtained by adding the driving time of the normal road section and the time for passing through the congested road section.

[0059] As shown in Figure 1 and Figure 2 The thermal management execution method provided by the application further includes:

[0060] S102, in response to determining that the estimated driving time is less than a first preset value, obtaining the temperature of the thermal management component.

[0061] In the above step S102, for example, the first preset value is 3 min, that is, when the estimated driving time of the vehicle is less than 3 min, it proves that the vehicle is close to the destination, and the subsequent driving time does not exceed 3 min. At this time, the subsequent step of obtaining the temperature of the thermal management component can be performed. When the estimated driving time of the vehicle is greater than or equal to 3 min, it proves that the vehicle will still drive for a period of time, and the temperature of the vehicle thermal management component will also increase with the increase of the driving time. Therefore, it is not suitable for the low-power operation of the thermal management system in the application.

[0062] Of course, the first preset value described in the present application is only for example, according to the outside environment temperature, the vehicle driving factors such as driving on flat road, uphill driving or downhill driving, the first preset value can also be selected as other values, for example, the vehicle is continuously uphill driving within the predicted driving time, at this time the thermal management component output power is larger, the temperature rises faster, then the first preset value is correspondingly reduced.

[0063] In the above step S102, the thermal management component refers to the execution object of the vehicle thermal management system for cooling, including motor related components, battery components, etc., the way to obtain the temperature of the thermal management component can be to directly obtain the temperature through the temperature sensor arranged on the corresponding thermal management component, or to collect the temperature of the cooling liquid in the liquid circulation loop, and to judge the temperature of the corresponding thermal management component through the temperature of the cooling liquid flowing through the thermal management component.

[0064] As shown in Figure 1 and Figure 2 The thermal management execution method provided by the present application further comprises:

[0065] S103, according to the upper limit temperature value of the thermal management component and the predicted driving time of the vehicle, determining the temperature critical value of the thermal management component capable of low-power running mode.

[0066] In some embodiments, in the above step S103, the upper limit temperature value of the thermal management component refers to the limit temperature that the motor related components or the battery components can reach without affecting their own service life and working performance, and exceeding the upper limit temperature value will seriously affect the working life of the thermal management component. Here, the upper limit temperature value can be obtained by the properties of the thermal management component itself.

[0067] In some embodiments, the temperature critical value of the thermal management component refers to a value lower than the upper limit temperature value. For example, the upper limit temperature value of the thermal management component minus the temperature rise value within the predicted driving time of the vehicle is the temperature critical value, and the specific formula is as follows:

[0068] t = T - m;

[0069] Wherein, t is the temperature critical value, T is the upper limit temperature value of the thermal management component; m is a constant.

[0070] In the above formula, the constant m is proportional to the predicted driving time of the vehicle, and the temperature critical value is inversely proportional to the predicted driving time of the vehicle, that is, the longer the predicted driving time of the vehicle, the larger the m, and the smaller the temperature critical value of the thermal management component, thereby the vehicle thermal management component can be heated from the temperature critical value to the upper limit temperature value for a longer time, so as to meet the low-power running mode of the thermal management system. For example, m is 10℃.

[0071] It should be noted that in some embodiments, the temperature of the heat management component can be a plurality of temperatures of a plurality of different heat management components, and when a plurality of temperatures of a plurality of different heat management components are obtained, the highest temperature in the obtained plurality of temperatures is used to satisfy the condition that the heat management component does not reach the upper limit temperature value after low-power consumption operation at the highest temperature; when the temperature of the heat management component is obtained by obtaining the temperature of the cooling liquid in the circulating loop, the temperature of the cooling liquid can be directly used as the reference.

[0072] As shown in Figure 1 and Figure 2 The heat management execution method provided by the present application further comprises:

[0073] S104, in response to determining that the temperature of the heat management component is less than or equal to the temperature threshold value, an execution signal corresponding to the low-power consumption operation mode is sent to the heat management system, so that the heat management system operates in the low-power consumption operation mode.

[0074] In the above step S104, the execution signal corresponding to the low-power consumption operation mode is sent to the heat management system, so that the heat management system operates in the low-power consumption operation mode, which comprises:

[0075] The execution signal corresponding to the low-power consumption operation mode is sent to the liquid circulating loop of the heat management system, so as to reduce the flow or cooling power of the cooling liquid in the liquid circulating loop; and / or,

[0076] The execution signal corresponding to the low-power consumption operation mode is sent to the cooling fan of the heat management system, so as to slow down the rotation rate of the cooling fan or shut down the cooling fan.

[0077] The above describes two forms of low-power consumption operation of the heat management system. In some embodiments, the cooling liquid in the liquid circulating loop cannot be empty due to the need to protect related components. Therefore, the low-power consumption operation mode of the heat management system includes the case of reducing the flow of the cooling liquid in the liquid circulating loop to the minimum value by controlling the water pump.

[0078] In some embodiments, after the above step S104, it further comprises:

[0079] S105, detecting the temperature of the heat management component.

[0080] S106, in response to determining that the temperature of the heat management component is less than the upper limit temperature value, the low-power consumption operation mode of the heat management system is maintained;

[0081] S107, in response to determining that the temperature of the heat management component is greater than or equal to the upper limit temperature value, a switching signal is sent to the heat management system to switch the low-power consumption operation mode of the heat management system to a non-low-power consumption operation mode.

[0082] The above steps are based on the scenario that the thermal management system has been running in low-power mode, when the vehicle is in driving state, the temperature of the thermal management component is continuously detected and obtained, when the detected temperature of the thermal management component is less than the upper limit temperature value, it proves that the temperature of the vehicle thermal management component is greater than the temperature critical value but has not reached the upper limit temperature value affecting the service life, at this time, the low-power running mode can be continued; when the detected temperature of the thermal management component is greater than or equal to the upper limit temperature value, it proves that the temperature of the thermal management component is too high and has reached a high temperature environment affecting the service life and working performance, therefore, the thermal management system needs to be switched to a non-low-power running mode.

[0083] Here, it should be noted that the non-low-power running mode of the thermal management system has higher output power, that is, the flow or cooling power of the cooling liquid in the liquid circulation loop is higher, or the rotating speed of the cooling fan is faster.

[0084] The above setting can further reduce the energy consumption of the thermal management execution, and at the same time, the use of step setting scenarios to adopt different execution strategies for the thermal management system can also ensure the intelligentization and humanization of the thermal management system and optimize the judgment logic of the thermal management system.

[0085] In some embodiments, in step S107, the non-low-power running mode includes a first preset running mode and a second preset running mode, and the output power consumption of the first preset running mode is greater than that of the second preset running mode.

[0086] For example, the first preset running mode corresponds to a thermal management cooling running mode under full power and high power consumption, in which state the water pump of the liquid circulation loop in the thermal management system has the maximum output power and the cooling fan is turned on and rotates at high speed; the second preset running mode corresponds to a thermal management cooling running mode under medium power and medium power consumption, in which state the water pump of the thermal management system has an output power of 50% of the full power and the fan is turned off.

[0087] It should be noted that the above-mentioned first preset running mode and second preset running mode are only illustrative, and for different driving scenarios, the first preset running mode and the second preset running mode can be adjusted, for example, in the first preset running mode, the water pump of the liquid circulation loop in the thermal management system has an output power of 50% of the full power and the cooling fan is turned on and rotates at high speed; in the second preset running mode, the water pump of the liquid circulation loop in the thermal management system maintains the minimum value and the cooling fan is turned on and rotates at high speed; as long as the output power consumption of the first preset running mode is greater than that of the second preset running mode.

[0088] Based on the above description, step S107 further includes:

[0089] In response to determining that the temperature of the thermal management component is greater than the upper limit temperature value, the ambient temperature is obtained;

[0090] In response to determining that the ambient temperature is greater than the second preset value, a switching signal is sent to the thermal management system to switch the low-power consumption operation mode of the thermal management system to the first preset operation mode;

[0091] In response to determining that the ambient temperature is less than or equal to the second preset value, a switching signal is sent to the thermal management system to switch the low-power consumption operation mode of the thermal management system to the second preset operation mode.

[0092] In the above steps, for example, the second preset value is 20℃. When the ambient temperature is greater than 20℃, the effect of natural wind cooling of the thermal management component through the ambient environment is very limited, and therefore, timely intervention of the thermal management system is needed to ensure that the thermal management component is rapidly cooled to below the upper limit temperature value. When the ambient temperature is less than or equal to 20℃, the thermal management component can be cooled through the natural wind cooling of the ambient environment, and therefore, only the second preset operation mode with relatively small power consumption is needed to meet the cooling effect of the thermal management component. This setting can further reduce the energy consumption of the thermal management, and at the same time, using the gradient setting scenario to adopt different execution strategies for the thermal management system can ensure the intelligentization and humanization of the thermal management system, and optimize the judgment logic of the thermal management system.

[0093] In some embodiments, after step S104, the method further comprises:

[0094] S108, in response to determining that the vehicle reaches the destination and the vehicle speed is less than or equal to a third preset value, the thermal management system is kept in the low-power consumption operation mode.

[0095] S109, in response to determining that the vehicle reaches the destination and the vehicle speed is greater than the third preset value, a switching signal is sent to the thermal management system to switch the low-power consumption operation mode of the thermal management system to a non-low-power consumption operation mode.

[0096] In some embodiments, in the above step S109, for example, the third preset value is 10km / h. When the vehicle speed is greater than 10km / h after the vehicle reaches the destination, it proves that the vehicle enters a new subsequent driving state, and the thermal management system is switched to the non-low-power consumption operation mode to avoid affecting the normal driving of the vehicle. When the vehicle speed is less than or equal to 10km / h after the vehicle reaches the destination, the vehicle is in a parking state or a low-speed driving state, and the thermal management system remains in the low-power consumption operation mode to further reduce energy output and thus reduce energy consumption as much as possible.

[0097] It should be noted that in addition to referring to the above destination position and vehicle speed, other factors can also be combined to determine whether the vehicle enters a new subsequent driving state, such as confirming whether the vehicle re-enters the parking space after entering the parking space, or receiving new navigation information from the user through the human-computer interaction platform, or detecting that the vehicle speed signal has been accelerated from 0 km / h to greater than 10 km / h, etc. Here, the non-low-power running mode can also refer to the first preset running mode or the second preset running mode described above.

[0098] In addition, in some embodiments, even if the vehicle has not reached the destination, when the vehicle speed is greater than 10 km / h for more than 2 minutes, it is proved that the vehicle is not in the parking state, and the vehicle is still in continuous driving. In this scenario, the vehicle control center sends a switching signal to the thermal management system to switch the low-power running mode of the thermal management system to the non-low-power running mode. Here, the parking state refers to the state of the vehicle approaching the destination and stopping after reaching the destination.

[0099] It should be noted that when the above parking state information does not appear, the setting of the vehicle speed value and the continuous driving time value is only an example, and as long as the vehicle control center determines that the vehicle does not have the intention to park, for example, by receiving new navigation information from the user through the human-computer interaction platform to determine that the vehicle does not have the intention to park, or by confirming that the vehicle has entered the elevated road or the highway to determine that the vehicle does not have the intention to park.

[0100] In summary, as shown in Figure 2 An exemplary description of the vehicle thermal management execution method provided by the present application is as follows:

[0101] When the vehicle is in the starting state, it is determined whether the vehicle is located on the highway according to the vehicle driving scene information. When the vehicle is not on the highway, it is determined whether the predicted driving time of the vehicle is less than 3 minutes according to the navigation destination information, the GPS signal, the traffic light information or the traffic congestion state information, etc. When the predicted driving time of the vehicle is less than 3 minutes, the temperature of the thermal management component is obtained, and it is determined whether the temperature of the thermal management component is less than or equal to the temperature threshold. When the temperature of the thermal management component is less than or equal to the temperature threshold, the vehicle control center controls the low-power running of the thermal management system, at this time, the power of the water pump in the liquid circulation loop is at the minimum value, and the cooling fan is turned off.

[0102] Subsequently, the temperature of the thermal management component is continuously detected in the low-power operation mode, when the temperature of the thermal management component is greater than or equal to the upper limit temperature value, and the obtained environmental temperature information is greater than 20℃, the vehicle central control controls the thermal management system to be in the first preset operation mode (full power, high-power operation mode); when the temperature of the thermal management component is greater than or equal to the upper limit temperature value, and the obtained environmental temperature information is less than or equal to 20℃, the vehicle central control controls the thermal management system to be in the second preset operation mode (medium power, medium-power operation mode).

[0103] The vehicle detects that the vehicle speed is greater than 10km / h again after being 0km / h during driving, and the vehicle central control controls the thermal management system to be in the first preset operation mode; if the vehicle speed is not monitored to be 0km / h, but the vehicle speed is greater than 10km / h and the driving time exceeds 2min, the vehicle central control controls the thermal management system to be in the first preset operation mode.

[0104] It should be noted that the method of the embodiments of the present application can be executed by a single device, such as a computer or a server, etc. The method of the embodiments can also be applied to a distributed scenario, and be completed by multiple devices cooperating with each other. In this distributed scenario, one of the multiple devices can only execute one or more steps in the method of the embodiments of the present application, and the multiple devices can interact with each other to complete the method.
