[0041] To make the objectives, technical solutions, and advantages of the present invention more apparent, exemplary embodiments according to the present invention will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are merely a part of the embodiments of the present invention, and not all of the embodiments of the present invention. It should be understood that the present invention is not limited to the exemplary embodiments described herein. Based on the embodiments of the present invention described herein, all other embodiments obtained by those skilled in the art without inventive effort should fall within the protection scope of the present invention.

[0042] A new energy vehicle thermal management system is a collection of components used to regulate the operating temperature environment of vehicle parts and the cabin temperature environment. Thermal management systems typically operate based on a single parameter. For example, automotive air conditioning adjusts its temperature based solely on the user-set target temperature for the passenger compartment on the control panel. Since users cannot frequently change this target temperature, energy consumption is wasted in certain driving scenarios. For instance, if a user keeps the windows open for an extended period and the air conditioning is set to recirculation mode, the interior temperature will eventually approach the ambient temperature. Continuously running the air conditioning at high power will not achieve the desired cooling effect, resulting in energy waste. To address the problem that existing vehicle thermal management methods cannot reduce energy consumption and improve vehicle range and fuel economy while meeting thermal management requirements, this application proposes a vehicle thermal management method, device, medium, and vehicle that can reduce vehicle energy consumption and improve vehicle range and fuel economy while meeting thermal management requirements. The following provides a detailed description of this method.

[0043] First, refer to Figure 1 This describes an example electronic device 100 for implementing embodiments of the method of the present invention.

[0044] like Figure 1 As shown, the electronic device 100 includes a processor 110, a memory 120, and a communication interface 130. The processor 110, the memory 120, and the communication interface 130 can be interconnected and communicate via a communication bus 140 and / or other forms of connection mechanisms (not shown).

[0045] It should be noted that Figure 1 The components and structures of the electronic device 100 shown are merely exemplary and not limiting; the electronic device 100 may also have other components and structures as needed.

[0046] Optionally, the communication interface 130 may also include a transmitter and / or a receiver.

[0047] The processor 110 may be a microcontroller unit (MCU), a central processing unit (CPU), a digital signal processor (DSP), a microcontroller, an embedded device, or other processing unit with data processing and / or instruction execution capabilities, and may control other components in the autonomous driving vehicle system to perform desired functions.

[0048] The memory 120 can be various forms of computer-readable storage media, such as volatile memory and / or non-volatile memory. Volatile memory may include, for example, random access memory (RAM), cache memory, synchronous dynamic random access memory (SDRAM), etc. Non-volatile memory may include, for example, read-only memory (ROM), hard disk, flash memory, etc. One or more computer program instructions may also be stored on the computer-readable storage medium, and the memory 120 can execute the program instructions to implement the vehicle thermal management method of the embodiments of the present invention described below.

[0049] Next, refer to Figure 2 This application describes a vehicle thermal management method according to embodiments thereof.

[0050] like Figure 2 As shown, this application provides a vehicle thermal management method applicable to electric vehicles or hybrid vehicles.

[0051] Here, an electric vehicle refers to a vehicle powered by an onboard power source and driven by an electric motor. A hybrid electric vehicle refers to a vehicle whose drive system consists of two or more individual drive systems that can operate simultaneously. The vehicle's driving power is provided individually or jointly by each individual drive system, depending on the actual driving conditions. Each drive system includes a drive motor. The method of this application, when applied to hybrid electric vehicles, is used in scenarios where the vehicle's driving power is provided by the drive motor based on the actual driving conditions.

[0052] Thermal management systems in electric or hybrid vehicles typically include air conditioning systems, engine assembly systems, battery thermal management systems, and motor and electronic control thermal management systems. The thermal management method described in this application can be applied to any one of these systems. When the system determines that a user has entered the vehicle and engaged Drive (D) gear, it assumes the vehicle is in motion, and the thermal management function will be activated simultaneously.

[0053] The vehicle thermal management method provided in this application may include the following steps S210-S230, and each step is described in detail below.

[0054] In step S210, temperature adjustment parameters are determined based on the vehicle's total navigation time and / or destination charging planning information.

[0055] In this application, the vehicle's navigation time is the travel time required from the current location to the destination, generated by the vehicle's navigation system.

[0056] In this application, destination charging planning information can include charging at the destination and not charging at the destination. Specifically, destination charging planning information can be determined based on the location information of charging stations at the destination. For example, if a charging station near the destination is within a preset distance range from the destination, charging will be carried out at the destination; if a charging station near the destination is within a preset distance range from the destination, charging will not be carried out at the destination.

[0057] It should be noted that the location information of charging stations can be determined based on the user's historical vehicle usage data. After the user turns on navigation and sets a destination, the location information of charging stations can be obtained based on historical data; alternatively, the location information of charging stations around the destination can be determined directly based on navigation data. This application does not specify a particular method for obtaining the location information of charging stations.

[0058] In one specific implementation, destination charging planning information can also be determined based on the vehicle's current driving range. For example, when a charging station is within a preset distance of the destination, if the vehicle's current driving range is greater than a preset mileage threshold, charging will not be performed at the destination; if the vehicle's current driving range is less than or equal to the preset mileage threshold, charging will not be performed at the destination.

[0059] Incorporating destination charging planning information into thermal management allows for the implementation of thermal management practices that prioritize meeting thermal management requirements, ensuring charging infrastructure is available at the destination and that charging stations can be prioritized upon arrival. For example, with the air conditioning system, if charging is planned at the destination, the target temperature for the passenger compartment can be adjusted to prioritize passenger comfort; conversely, if charging is not planned at the destination, the target temperature adjustment should prioritize energy conservation.

[0060] Thermal management considers the total navigation time of the current trip, allowing for thermal management that prioritizes meeting thermal management needs even when the trip is long. For example, when navigation time is long, air conditioning temperature control tends to prioritize user comfort, with smaller values ​​for the target cabin temperature adjustment parameter, meaning a smaller deviation from the target temperature. When the trip distance is short or the destination is approaching, considering the high energy consumption of adjusting the cabin temperature in high and low temperature environments, and the short remaining usage time for users, the strategy will adopt a more economical approach to controlling the cabin temperature, resulting in a larger value for the target cabin temperature adjustment parameter.

[0061] Similarly, when the navigation time is long, the battery temperature control tends to prioritize battery performance, and the temperature adjustment parameter for the target battery temperature is set to a smaller value. When the journey distance is short or the destination is approaching, the strategy will adopt a more economical approach to control the battery temperature, that is, the temperature adjustment parameter for the target battery temperature will be set to a larger value.

[0062] In this application, the method for determining temperature adjustment parameters based on the vehicle's total navigation time or destination charging planning information may include:

[0063] Get route navigation time or destination charging planning information;

[0064] Based on the navigation time, retrieve the corresponding adjustment parameter value from the pre-obtained correspondence data between navigation time and adjustment parameters; or,

[0065] Based on the destination charging plan information, the adjustment parameter values ​​corresponding to the destination charging plan information are retrieved from the pre-obtained correspondence data between the destination charging plan information and the adjustment parameters.

[0066] In this application, the method for determining temperature adjustment parameters based on the vehicle's total navigation time and destination charging planning information may include:

[0067] Obtain route navigation time and destination charging planning information;

[0068] Based on the navigation time and destination charging planning information, the adjustment parameter values ​​corresponding to the navigation time and destination charging planning information are retrieved from the pre-obtained correspondence data between navigation time, destination charging planning information and adjustment parameters.

[0069] In step S220, the target temperature of the vehicle is determined based on the temperature adjustment parameters.

[0070] In this step, the initial target temperature is first obtained, and then the initial target temperature is adjusted based on the temperature adjustment parameters. The adjusted temperature is then used as the target temperature for vehicle thermal management.

[0071] For example, when a vehicle's thermal management method is applied to the air conditioning system, the initial target temperature is the target temperature value for the passenger compartment. Specifically, this temperature value is determined based on the passenger compartment target temperature set on the control panel during the user's driving process. The target temperature for the passenger compartment is obtained by summing the temperature adjustment parameters with the user-set passenger compartment target temperature on the control panel.

[0072] For example, when vehicle thermal management methods are applied to battery thermal management systems, since new energy vehicles use battery power as their driving energy, battery capacity is low and charging / discharging performance is poor at low temperatures; at high temperatures, battery cycle life is shortened, and operating at excessively high temperatures can even lead to safety issues such as explosions. Therefore, the optimal operating temperature for power batteries is between 10-30℃. Furthermore, fast charging requires preheating of the battery cells, but excessively high temperatures will accelerate cell aging. Therefore, a thermal management system is needed to ensure that the battery cells are within a reasonable temperature range. The initial target temperature in this case is the preset target temperature within the thermal management system.

[0073] In this application, the initial target temperature can be determined by existing methods, and this application does not specifically limit the initial target temperature or the method for determining it.

[0074] In step S230, thermal management of the vehicle is performed based on the target temperature.

[0075] In this application, the method for thermal management of a vehicle based on a target temperature can employ either feedforward control or feedback control, thereby enabling the corresponding system or cabin to reach the target temperature.

[0076] The vehicle thermal management method of this application adjusts the initial target temperature based on the total navigation time and / or destination charging planning information, thereby reducing vehicle energy consumption and improving vehicle range and economy while meeting vehicle thermal management requirements.

[0077] According to one embodiment of this application, temperature adjustment parameters are determined based on the vehicle's total navigation time and destination charging planning information, including:

[0078] The first adjustment parameter is determined based on the destination charging plan information;

[0079] The second adjustment parameter is determined based on the total navigation time;

[0080] When the total navigation time exceeds the time threshold, the smaller value between the first adjustment parameter and the second adjustment parameter will be used as the temperature adjustment parameter.

[0081] When the total navigation time is less than or equal to the time threshold, the larger of the first adjustment parameter and the second adjustment parameter will be used as the temperature adjustment parameter.

[0082] In this embodiment, the method for determining the first adjustment parameter and the second adjustment parameter is not specifically limited. For example, the value of the first adjustment parameter corresponding to the navigation time can be obtained from pre-obtained data on the correspondence between navigation time and adjustment parameters.

[0083] According to one embodiment of this application, the method further includes: updating the temperature adjustment parameters based on vehicle status information and / or environmental information, wherein the status information includes one or more of engine coolant temperature, vehicle window opening information, passenger information, and real-time battery temperature information.

[0084] When vehicle thermal management methods are applied to air conditioning systems, temperature adjustment parameters can be determined based on vehicle status information and / or environmental information. At this time, the status information includes one or more of the following: engine coolant temperature, vehicle window opening information, and passenger information.

[0085] When vehicle thermal management methods are applied to battery thermal management systems, temperature adjustment parameters can be determined based on vehicle status information and / or environmental information. In this case, the status information includes real-time battery temperature information. For example, when performing thermal management on the battery under high / low temperature conditions, heating / cooling the battery is required. By acquiring information such as ambient temperature, real-time battery temperature, destination charging plan information, and remaining navigation time, adjustment parameters are determined to adjust the target temperature, thereby achieving comprehensive lookup-based correction of the target battery temperature. Simultaneously, the target battery temperature can be further corrected by combining information such as whether the user plugged in the charging gun before driving and related information (the battery also generates heat during charging).

[0086] Passenger cabin comfort is a key indicator for evaluating overall vehicle performance. By summarizing other factors that affect passenger cabin comfort and overall vehicle energy consumption during driving, this embodiment uses vehicle status information and / or environmental information as influencing factors for temperature adjustment parameters. This allows for more reasonable and precise control of the target temperature in the air-conditioned passenger cabin, which can reduce overall vehicle energy consumption without affecting passenger cabin comfort, thus achieving energy-saving effects.

[0087] In this embodiment, the engine water tank temperature can be collected by a temperature sensor, and the passenger information includes the number of passengers, which can be collected by a pressure sensor and / or determined by the seat belt wearing status; the vehicle window opening information includes the opening degree of each window, which can be determined by a Hall position sensor to determine the motor position.

[0088] When determining temperature adjustment parameters based on vehicle window opening information, if the windows are open, the cooling temperature can be appropriately increased or the heating temperature can be decreased to reduce energy consumption while ensuring comfort.

[0089] During the heating process of the passenger compartment, the temperature adjustment parameters can be determined based on the engine water tank temperature. When the engine water temperature is high, the waste heat of the engine can be used to heat the passenger compartment, and the target heating temperature of the air conditioner can be reduced at the same time, so as to use more engine heating and reduce the overall vehicle energy consumption without affecting the comfort of the passenger compartment.

[0090] Temperature adjustment parameters can also be determined based on passenger information. For example, based on information such as child abandonment monitoring, seat pressure sensors, and whether seat belts are fastened, the distribution of people in each seat in the vehicle can be obtained, and the car's air conditioning can be controlled to ensure the comfort of people in different areas of the vehicle.

[0091] In this embodiment, environmental information may include outside temperature, inside temperature, and weather information, with weather information including light intensity. Outside temperature and inside temperature can be collected using inside / outside temperature sensors, and sunlight intensity can be collected using a light intensity sensor.

[0092] By adjusting the air conditioning target temperature setting based on the user's arrival time at the destination, taking into account the destination's charging status and environmental information, the system can better regulate the passenger compartment temperature based on various data while maintaining overall vehicle functionality during driving. This improves user comfort while conserving energy in high-voltage components such as the vehicle battery and air conditioning compressor, thereby increasing the vehicle's range and fuel economy.

[0093] According to one embodiment of this application, a method for updating temperature adjustment parameters based on vehicle status information and environmental information includes:

[0094] The third adjustment parameter is determined based on the status information;

[0095] The fourth adjustment parameter is determined based on environmental information;

[0096] After obtaining the third and fourth adjustment parameters, the third and fourth adjustment parameters are compared with the temperature adjustment parameters determined solely based on the vehicle's total navigation time and destination charging planning information. When the total navigation time is greater than the time threshold, the smaller of the three parameters is used as the final temperature adjustment parameter; when the total navigation time is less than or equal to the time threshold, the larger of the three parameters is used as the final temperature adjustment parameter.

[0097] The vehicle thermal management method in this embodiment generates a target temperature deviation value for the passenger compartment based on current environmental information, status information, estimated remaining driving time for the current trip, destination charging plan, and other information. This corrects the passenger compartment temperature set by the user on the control panel. While meeting the overall vehicle functions during driving, it can adjust the passenger compartment temperature to a greater extent according to different data information. This improves user comfort while saving energy consumption of high-voltage components such as the vehicle battery and air conditioning compressor, thereby increasing the vehicle's range and economy.

[0098] According to one embodiment of this application, determining a fourth adjustment parameter based on environmental information includes:

[0099] Based on the environmental information, the value of the fourth adjustment parameter corresponding to the environmental information is obtained from the pre-obtained correspondence data between the environmental information and the fourth adjustment parameter.

[0100] In a specific implementation, the methods for generating correspondence data include:

[0101] Based on environmental information classification, the characteristic environmental information of each category is determined;

[0102] By inputting various characteristic environmental information into a pre-established vehicle simulation model, adjustment data that meets the vehicle's thermal management and energy consumption requirements can be obtained.

[0103] The corresponding relationship data is generated based on the characteristic environment information and adjustment data.

[0104] Here, based on environmental information classification, characteristic environmental information of different categories can be determined through big data and research papers; based on a multi-physics, cross-domain fusion simulation platform, characteristic environmental information, navigation information, and intelligent driving information are used as inputs to perform large-scale scanning calculations; the results of the lowest overall vehicle energy consumption and the best passenger cabin comfort are extracted from the calculation results as data for the deviation table.

[0105] In a specific implementation, the method for generating the corresponding relationship data can also employ real-vehicle testing. For example, when generating the corresponding data between adjustment parameters and window openings for different window opening degrees, the strategy and its initial table values ​​are written into the real vehicle. The vehicle is then driven in a specific environment, such as a high-temperature environment of 40°C, or with all four windows open during driving. By modifying the values ​​in the table under specific scenarios, it is possible to identify whether the vehicle experiences thermal safety issues, and simultaneously analyze vehicle energy consumption. If the vehicle does not experience thermal safety issues and its overall energy consumption is at its lowest, the values ​​in the table are determined. This method is used to determine all the values ​​in the table.

[0106] Taking window opening information as an example, by establishing a two-dimensional table of the number of windows and the window opening degree on the deviation of the target temperature of the passenger cabin, the correction parameters of the target temperature of the passenger cabin under the cooling / heating state are determined, as shown in Table 1 and Table 2 below. Table 1 is the air conditioning target temperature deviation (°C) under different window opening information, and Table 2 is the air conditioning target temperature deviation (°C) under different window opening information.

[0107] Table 1

[0108]

[0109] Table 2

[0110]

[0111] Finally, by conducting real-vehicle tests on each influencing factor, a multi-dimensional target temperature deviation table for the passenger compartment can be obtained.

[0112] Next, see Figure 3 This application describes a thermal management method for an air conditioning system according to an embodiment of the present application.

[0113] The execution subject of the method in this embodiment is the control module of the air conditioning system. The control module can obtain relevant vehicle information, environmental information, location and destination information through the integrated information module to achieve comprehensive control of the target temperature of the passenger cabin.

[0114] like Figure 3 As shown, the thermal management method for an air conditioning system includes the following steps:

[0115] (1) Determine whether the user has entered the navigation destination. If the result is yes, obtain the route navigation time and generate the target temperature deviation value T1 of the passenger cabin. Otherwise, the navigation information will not be used as reference information for temperature adjustment.

[0116] (2) Based on the user's historical driving habits and charging behavior, statistically analyze the user's N nearest driving destinations and whether the user completed charging upon arrival at the destination. If the user has completed charging more than m times consecutively at that location, the destination is considered to have charging conditions. If the user has failed to charge for m consecutive times, the destination does not have charging conditions. During actual vehicle use, the system determines whether the user-input destination information has charging conditions. If it does, a target temperature deviation value T2 for the passenger compartment is generated; otherwise, the destination charging condition information will not be used as reference information for temperature adjustment.

[0117] (3) Generate the target temperature deviation value T3 of the passenger compartment based on the outside temperature.

[0118] (4) Generate the target temperature deviation value T4 of the passenger compartment based on the weather information (light intensity) outside the vehicle returned by the current light sensor.

[0119] (5) Obtain the window opening and the corresponding number of people on board, and generate the target temperature deviation value T5 of the passenger compartment by looking up the table based on the window opening.

[0120] (6) Determine if the vehicle is in passenger compartment heating mode. If not, the engine coolant temperature will not be used as a reference for temperature adjustment. If yes, determine whether the current engine coolant temperature collected by the temperature sensor is higher than the target coolant temperature T. lim If no, the engine coolant temperature will not be used as a reference for temperature regulation. If yes, the target temperature deviation value T6 for the passenger compartment will be generated by looking up the table based on the current engine coolant temperature.

[0121] (7) Determine whether the current user's time away from the destination is greater than the critical time t. lim If yes, then the value with the smallest absolute value among T1, T2, T3, T4, T5, and T6 will be used as the final target temperature deviation value for the crew cabin. If no, then the value with the largest absolute value among T1, T2, T3, T4, T5, and T6 will be used as the final target temperature deviation value for the crew cabin.

[0122] (8) Sum the target temperature deviation value obtained in (7) with the target temperature value of the passenger compartment set by the user to obtain a new target temperature value of the passenger compartment, and then end.
