[0002] In the field of vehicle energy utilization, with the increasing prominence of energy issues and the continuous improvement of users' requirements for vehicle economy and comfort, the effective recovery and utilization of vehicle waste heat has become a key research direction. Currently, during vehicle operation, components such as the engine, motor, and battery generate a large amount of waste heat. This waste heat is often dissipated directly into the surrounding environment without being fully utilized, resulting in significant energy waste. At the same time, users often need to heat household items during vehicle operation, such as food and beverages, but current vehicles lack corresponding waste heat recovery and utilization devices, failing to meet these diverse user needs and reducing user comfort and convenience in vehicle usage scenarios.

[0051] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0052] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0053] Currently, while some vehicles on the market have made initial explorations into waste heat recovery—for example, some vehicles use the waste heat from engine coolant to heat the vehicle interior—this recovery method is relatively simple, only meeting basic heating needs and failing to address the heating needs of other household items. Furthermore, most existing waste heat recovery devices lack the ability to dynamically adjust based on user heating needs and vehicle operating status, making it impossible to precisely set waste heat recovery and heating parameters. This results in low waste heat recovery efficiency and significant energy waste. Simultaneously, due to the lack of heating containers and control methods specifically designed for heating household items, even if users need to heat food or beverages, it is difficult to do so conveniently and efficiently while the vehicle is in operation, greatly limiting the user experience and comfort in vehicle usage scenarios.

[0054] In view of this, this application provides a method for recovering and utilizing waste heat from a vehicle. This method determines the waste heat recovery parameters and the heating parameters of the vehicle's heating container based on the user's heating needs and the vehicle's operating status. Then, waste heat generated during vehicle operation is recovered according to the waste heat recovery parameters, and the heating container is controlled to use this waste heat to heat the materials inside. This achieves efficient recovery and precise utilization of vehicle waste heat, fully tapping into the energy potential wasted during vehicle operation, thereby reducing overall vehicle energy consumption and meeting diverse user heating needs. It provides users with convenient and efficient heating services for daily necessities during vehicle operation, improving user comfort and convenience in vehicle usage scenarios.

[0055] Figure 1 This is a schematic diagram of a waste heat recovery system for a vehicle provided in an embodiment of this application. Figure 1 As shown, the system may include: a controller, a heat exchanger, and a heating container.

[0056] The heat exchanger can be connected to one or more of the vehicle's engine cooling system, drive motor cooling system, and battery cooling system. During vehicle operation, the heat exchanger absorbs heat generated by the engine, drive motor, battery, etc., and directs this heat to a heating container. For example, coolant from the cooling system can flow through the heat exchanger to allow it to absorb waste heat from the vehicle. Furthermore, this coolant can be directed to a heating device or a dedicated heat storage device in the heating container to provide heating energy.

[0057] Heating containers are used to heat everyday items, such as water, beverages, and food. Examples of such containers include hot water tanks and food heating containers. Inside the heating container, heat is efficiently transferred to the food being heated through heat-conducting materials.

[0058] The controller is used to control the operating parameters of the heat exchanger and heating container, such as the waste heat recovery parameters of the heat exchanger and the heating parameters of the heating container. The controller can adaptively adjust the waste heat recovery parameters of the heat exchanger and the heating parameters of the heating container according to the user's heating needs and the vehicle's operating status to meet the user's heating requirements for domestic materials and efficiently utilize the waste heat generated during vehicle operation. Optionally, the controller can be an existing control unit on the vehicle, such as the engine control unit (ECU) or the central processing unit (CPU) of the vehicle's infotainment system, or it can be a separate control device such as a microcontroller unit (MCU) or a programmable logic controller (PLC) used to control the operating parameters of the heat exchanger and heating container.

[0059] Below, with Figure 1 The controller shown is the execution entity. Specific embodiments are used to describe in detail the technical solution of this application and how the technical solution solves the aforementioned technical problems. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0060] Figure 2 This is a schematic flowchart illustrating a method for recovering and utilizing waste heat from a vehicle, as provided in an embodiment of this application. Figure 2 As shown, the method may include:

[0061] S201. Based on the user's heating needs and the vehicle's operating status, determine the vehicle's waste heat recovery parameters and the vehicle's heating container's heating parameters.

[0062] In real-world scenarios, a vehicle's operating status is determined by multiple factors, including the power source's operating status, road conditions, and the external environment. Taking hybrid vehicles as an example, their power source includes an engine and an electric motor. Under different operating modes, the load on the engine and electric motor varies, resulting in different amounts of waste heat. When a vehicle is in congested urban traffic, frequent start-stop cycles cause instability in the engine and electric motor's operating status, leading to relatively unstable waste heat generation. Conversely, when driving on highways, the engine or electric motor operates in a more stable state, resulting in relatively stable waste heat generation.

[0063] Users' heating needs are determined based on their specific usage scenarios and expectations. For example, users may want to heat the drinking water in their car to a suitable drinking temperature in cold weather; or heat some food to meet their meal needs during long journeys.

[0064] One possible implementation approach is to determine waste heat recovery parameters based on the vehicle's operating status and heating parameters based on the user's heating needs. This approach involves, for example, analyzing factors such as the vehicle's power source operating status, road conditions, and external environment. If the vehicle's power source is operating under high load, such as high engine speed or high current output from the electric motor, the waste heat recovery flow rate can be increased to obtain more waste heat. Simultaneously, based on the power source's heating characteristics, an appropriate recovery interval can be determined to avoid excessive recovery affecting power source performance. Regarding road conditions, in congested traffic, due to unstable waste heat generation, intermittent recovery can be used, and the recovery flow rate can be appropriately reduced. On highways, a continuous and stable recovery method can be used to improve recovery efficiency. When the external ambient temperature is low, the recovered heat reserve can be increased, and vice versa. As for heating parameters, the heating power and heating time of the heating container can be determined based on the type of living materials being heated by the user. For example, when heating water, the heating power and heating time can be determined based on the specific heat capacity of water and the user's desired water temperature. When heating food, the characteristics of the food, such as its cooking speed and moisture content, need to be considered, and the appropriate heating temperature and time can be determined by combining the user's desired taste and heating effect.

[0065] Another possible approach is to determine the waste heat recovery parameters and heating parameters comprehensively based on the vehicle's operating status and the user's heating needs.

[0066] In this implementation, determining the waste heat recovery parameters requires comprehensive consideration of both the vehicle's waste heat generation and the user's heating needs. Waste heat recovery parameters can include the location of waste heat recovery, the flow rate, and the recovery time. In hybrid vehicles, the heat generated by the engine and electric motor can be recovered in different ways. The high-temperature exhaust gas from the engine can be recovered through an exhaust gas recirculation system, while the heat generated by the electric motor can be recovered through a coolant circulation system. The recovery flow rate needs to be adjusted based on the user's heating needs and the vehicle's waste heat generation. If the user's heating needs are high and the vehicle's waste heat generation is sufficient, the recovery flow rate can be increased appropriately; conversely, the recovery flow rate can be decreased. The recovery time needs to be determined based on the vehicle's operating status and the user's heating needs. During vehicle operation, if the user has a heating need, the waste heat recovery system can be activated promptly; when the vehicle is parked, if the vehicle still has waste heat and the user has a subsequent heating need, waste heat recovery can continue. Alternatively, when the vehicle is not running, the vehicle's battery power can be used to continue the heating process, ensuring that the user can obtain hot water or hot food when needed.

[0067] The heating parameters of the vehicle's heating container need to be determined based on the user's heating needs and the amount of waste heat recovered. These parameters may include the heating temperature, heating duration, and heating power. If the user wants to heat drinking water to a suitable temperature, they can determine the appropriate heating temperature and duration based on the recovered waste heat and the performance of the heating container. Furthermore, to ensure heating efficiency and safety, the heating parameters also need to be adjusted according to the heating container's power.

[0068] S202. Recover the waste heat generated during vehicle operation according to the waste heat recovery parameters.

[0069] Once the waste heat recovery parameters are determined, the waste heat generated during vehicle operation can be recovered according to these parameters. Taking the location of waste heat recovery as an example, if it is determined that waste heat recovery will be carried out at the engine exhaust outlet, a heat exchanger can be installed at the exhaust outlet. The heat exchanger can transfer the heat in the exhaust gas to the coolant, and the coolant will absorb the heat and its temperature will rise.

[0070] To control the flow rate of waste heat recovery, the speed of the water pump in the coolant circulation system can be adjusted. The higher the pump speed, the faster the coolant circulates, and the more waste heat is recovered. Simultaneously, the flow rate of the coolant can be controlled by adjusting the valve opening of the heat exchanger, thereby further refining the control of the waste heat recovery flow rate.

[0071] The timing of waste heat recovery can be managed through the vehicle's control system. During vehicle operation, the control system monitors the vehicle's operating status and the user's heating needs in real time. If the user requires heating, the control system can promptly activate the waste heat recovery system; conversely, when the user's heating needs are met or the vehicle's waste heat generation is insufficient, the control system can stop the waste heat recovery system to conserve energy.

[0072] S203. Based on the heating parameters, control the heating container to use waste heat to heat the domestic materials inside the heating container.

[0073] After recovering the waste heat generated during vehicle operation, the heating container can be controlled to use this waste heat to heat the living materials inside the heating container based on the heating parameters.

[0074] For example, taking the heating of drinking water as an example, a temperature sensor and a controller can be installed inside the heating container. The temperature sensor can monitor the temperature of the drinking water in real time and feed the temperature information back to the controller. The controller compares the heating temperature setpoint in the heating parameters with the actual monitored water temperature. If the water temperature is lower than the setpoint, the controller can control the heating container to connect to the waste heat recovery system through a heat exchange device, allowing the coolant carrying waste heat to transfer heat to the drinking water, thus raising the water temperature; when the water temperature approaches or reaches the setpoint, the controller can adjust the efficiency of the heat exchange or reduce the heat input to avoid the water temperature from becoming too high.

[0075] The heating duration can be controlled by a timer. The timer automatically stops connecting the heating container to the waste heat recovery system after the set heating duration is reached, thus stopping heating and ensuring efficient energy utilization. Furthermore, to improve heating efficiency and uniformity, a stirring device can be installed inside the heating container to ensure that the materials are heated evenly during the heating process.

[0076] The method provided in this application determines the waste heat recovery parameters and heating parameters of the vehicle's heating container based on the user's heating needs and the vehicle's operating status. Then, it recovers the waste heat generated during vehicle operation according to the waste heat recovery parameters, and controls the heating container to use this waste heat to heat the materials inside, thereby achieving efficient recovery and precise utilization of vehicle waste heat. This fully taps into the energy potential wasted during vehicle operation, reducing overall vehicle energy consumption and meeting diverse user heating needs. It provides convenient and efficient heating services for household materials during vehicle operation, improving user comfort and convenience in vehicle usage scenarios.

[0077] The following section provides a detailed explanation of how, in step S201, the waste heat recovery parameters of the vehicle and the heating parameters of the vehicle's heating container are determined based on the user's heating needs and the vehicle's operating status. Figure 3 This is a schematic flowchart illustrating another method for recovering and utilizing waste heat from a vehicle, provided as an embodiment of this application. Figure 3 As shown, the aforementioned step S201 may specifically include:

[0078] S301. Determine the waste heat supply capacity of the vehicle based on its operating status.

[0079] The vehicle's operating status encompasses multiple aspects of information and plays a crucial role in determining its waste heat supply capacity. The operating status of the powertrain is one of the most important influencing factors. In traditional gasoline-powered vehicles, engine speed and load directly determine the heat generated. Higher engine speeds result in more intense combustion, leading to increased heat generation; conversely, higher engine loads, such as when climbing hills or accelerating, require more fuel combustion for power, resulting in greater heat generation. In electric vehicles, the electric motor's power and operating time affect its heat generation. Higher motor power increases the heat generated by current flowing through the windings; and prolonged continuous operation raises the motor's temperature, generating even more waste heat.

[0080] The driving conditions also affect the waste heat supply capacity. In congested urban traffic, vehicles frequently start and stop, requiring the engine or electric motor to constantly adjust its operating state, which leads to reduced efficiency and relatively more heat generation. On highways, vehicles maintain a relatively stable speed, and the engine or electric motor operates in a relatively stable state, generating relatively less heat. However, due to the longer driving time, the overall amount of waste heat generated can still be considerable.

[0081] External ambient temperature also affects a vehicle's waste heat supply capacity. In cold environments, vehicles need to consume more energy to maintain the temperature of components such as the engine and electric motor in order to operate normally, which causes these components to generate more heat. In hot environments, the increased demand for heat dissipation may result in a relative decrease in waste heat generation.

[0082] To determine a vehicle's waste heat supply capacity, temperature monitoring of various key components can be performed. Temperature sensors are installed at critical locations in the engine or electric motor to acquire real-time temperature information. Simultaneously, by combining this data with information such as vehicle speed and powertrain output, an assessment model for waste heat supply capacity can be established. This model can comprehensively calculate the vehicle's waste heat supply capacity under its current operating conditions based on temperature data from the temperature sensors, speed information, and power output information. For example, based on factors such as the engine's temperature change rate, power output, and speed, the heat generated by the engine per unit time can be calculated, thereby determining the waste heat supply capacity.

[0083] S302. Based on the waste heat supply capacity and user heating needs, determine the waste heat recovery parameters and heating parameters of the vehicle.

[0084] One possible approach is to first conduct a detailed analysis and quantification of the user's heating needs. These needs can include the types of household items to be heated, the desired heating temperature, and the required heating time. Different types of household items have different thermal properties; for example, water has a high specific heat capacity and requires a significant amount of heat to reach a certain temperature. The heating requirements for some foods may be more complex, needing to consider the preservation of their taste and nutritional components.

[0085] After quantifying the user's heating needs, they can be compared with the waste heat supply capacity. If the waste heat supply capacity is greater than or equal to the user's heating needs, it indicates that the waste heat generated by the vehicle is sufficient to meet the user's heating requirements. In this case, waste heat recovery parameters and heating parameters can be determined based on the user's heating needs. For example, if a user needs to heat a certain amount of water to a specific temperature, the required heat can be calculated based on the water's mass, specific heat capacity, and desired heating temperature. Then, based on the waste heat supply capacity, a suitable waste heat recovery location, recovery flow rate, and recovery time can be determined to ensure sufficient heat is obtained. Simultaneously, heating parameters such as the heating temperature setting, heating duration, and heating power can be determined based on the performance of the heating container and the thermal characteristics of water.

[0086] Another possible approach is to introduce an optimization algorithm to determine waste heat recovery and heating parameters, taking into account user heating needs and waste heat supply capacity. The goal of this optimization algorithm is to maximize waste heat utilization efficiency and reduce energy consumption while meeting user heating requirements.

[0087] Optionally, this step can be implemented, for example, through the following sub-steps:

[0088] S3021. Determine the heating requirement based on the user's heating needs.

[0089] In this step, we can first identify the types of household materials to be heated. Different household materials have different physical and chemical properties, and their heating requirements will also differ. For example, for liquid household materials such as water and milk, we need to consider their mass, initial temperature, and desired heating temperature; for solid household materials such as bread and meat, in addition to considering mass and temperature, we also need to consider their internal heat conduction characteristics and heating uniformity requirements.

[0090] Then, the required heat can be calculated based on the thermal properties of the heating materials and the user's desired heating effect. For liquid heating materials, according to the specific heat capacity formula, the required heat equals the mass of the heating material multiplied by its specific heat capacity and then multiplied by the temperature change. For solid heating materials, due to their more complex thermal conductivity characteristics, the required heat can be estimated through experiments or empirical formulas. Simultaneously, heat losses during the heating process must be considered, such as heat dissipation from the heating container and energy losses during heat exchange. These heat losses are taken into account, and the calculated heat is corrected to finally determine the heating demand.

[0091] Alternatively, the user's heating requirements may include the heating quantity, in which case the heating quantity can be directly extracted from the user's heating requirements.

[0092] S3022. When the waste heat supply capacity is greater than or equal to the heating demand, determine the waste heat recovery parameters and heating parameters based on the heating demand.

[0093] When the waste heat supply capacity is greater than or equal to the heating demand, it indicates that the waste heat generated by the vehicle is sufficient to meet the user's heating needs. In this case, the waste heat recovery parameters and heating parameters can be determined based on the heating demand.

[0094] When determining waste heat recovery parameters, the location of waste heat recovery should be considered first. Based on the vehicle's structure and the distribution of waste heat generation, the location that can most effectively capture waste heat should be selected. In traditional gasoline vehicles, the engine's exhaust system and cooling system are typically where waste heat is concentrated; in electric vehicles, the electric motor's cooling system and the battery's thermal management system may generate significant amounts of waste heat. Choosing an appropriate waste heat recovery location can improve the efficiency of waste heat recovery.

[0095] The flow rate for waste heat recovery needs to be determined based on the heating demand and the temperature of the waste heat. If the waste heat temperature is high, the required recovery flow rate can be relatively small; conversely, if the waste heat temperature is low, a larger recovery flow rate is needed to obtain sufficient heat. The waste heat recovery flow rate can be controlled by adjusting the coolant flow rate or the exhaust gas flow rate of the heat exchanger.

[0096] The time required for waste heat recovery also needs to be determined based on the heating demand. If the heating demand is large, it may take a long time to recover enough waste heat; conversely, if the heating demand is small, waste heat recovery can be completed in a shorter time.

[0097] When determining heating parameters, the heating temperature setting of the heating container needs to be based on the user's desired heating temperature for the materials. Simultaneously, to ensure heating uniformity and safety, the performance and heat transfer characteristics of the heating container must also be considered. The heating duration can be calculated based on the heating demand and the heating power of the heating container. Higher heating power requires a shorter heating duration; conversely, lower power requires a longer heating duration.

[0098] S3023. When the waste heat supply capacity is less than the heating demand, analyze the urgency characteristics of the user's heating demand.

[0099] When the waste heat supply capacity is less than the heating demand, it is necessary to analyze the urgency characteristics of users' heating needs. The urgency of users' heating needs can be determined by several factors. For example, it can be determined based on the user's usage time. If a user needs to heat household items in a short time, such as quickly heating a cup of water when in a hurry, then the urgency of the heating demand is high; conversely, if the user does not have a specific time requirement, or can wait a longer time to complete the heating, then the urgency of the heating demand is low.

[0100] Alternatively, the urgency level can be determined based on the nature of the food items. For perishable foods such as dairy products, heating is required as soon as possible to ensure their quality and safety, thus the urgency level of this heating requirement is relatively high. On the other hand, for relatively stable food items such as biscuits and bread, the urgency level of the heating requirement is relatively low.

[0101] Alternatively, a user's specific needs can also be used as a basis for judging the level of urgency. For example, a user may have certain illnesses and need to drink warm beverages promptly; in this case, the urgency of the heating requirement is higher.

[0102] One possible approach is to establish an urgency assessment model to analyze the urgency characteristics of users' heating needs. This model can comprehensively consider the above-mentioned factors and assign an urgency weight to each heating need. By analyzing and processing the heating need information input by the user, the urgency score of the heating need can be calculated using this assessment model. The higher the score, the higher the urgency of the heating need.

[0103] Another possible approach is to determine the urgency level of the heating requirement based on the user's preset urgency level.

[0104] S3024. Based on the urgency level, user heating needs are divided into priority heating needs and non-priority heating needs.

[0105] After analyzing the urgency characteristics of users' heating needs, these needs can be divided into priority heating needs and non-priority heating needs based on their urgency scores. For example, an urgency threshold can be set, classifying heating needs with urgency scores above the threshold as priority heating needs and those with scores below the threshold as non-priority heating needs.

[0106] For example, if the urgency score ranges from 0 to 100, and the threshold is set at 60, then heating needs with an urgency score of 60 or higher, such as a user urgently needing to heat a cup of hot water to take medication in a short time, fall into the category of priority heating needs; while heating needs with an urgency score below 60, such as a user needing to heat some bread a longer time later, fall into the category of non-priority heating needs.

[0107] By breaking down user heating needs, limited waste heat resources can be allocated more rationally, prioritizing heating needs with higher urgency and improving user satisfaction.

[0108] S3025. Based on the heating demand and waste heat supply capacity of the priority heating demand section, determine the waste heat recovery parameters and heating parameters for the corresponding priority heating demand section.

[0109] After determining the priority heating demand, the corresponding waste heat recovery parameters and heating parameters need to be determined based on the heating demand and waste heat supply capacity of that part.

[0110] First, the required amount of waste heat recovery can be calculated based on the heating demand of the priority heating components. Since waste heat supply capacity is limited, waste heat resources need to be allocated rationally while meeting priority heating needs. The required heat can be accurately calculated based on factors such as the type of domestic materials requiring priority heating, the desired heating temperature, and the heating time. Then, combined with the waste heat supply capacity, the amount of waste heat that can be recovered from the vehicle can be determined.

[0111] When determining waste heat recovery parameters, greater emphasis should be placed on the efficiency and targeting of waste heat recovery. For example, the flow rate and time of waste heat recovery can be adjusted according to the required amount of waste heat to be recovered. If the waste heat supply capacity is relatively sufficient, the recovery flow rate can be appropriately increased and the recovery time shortened; if the waste heat supply capacity is relatively tight, the recovery flow rate and time need to be reasonably controlled to ensure that sufficient waste heat can be obtained.

[0112] Heating parameters need to be set according to the characteristics of the areas with priority heating needs. The heating temperature can be determined based on the user's desired heating temperature for the materials to ensure heating effectiveness. The heating duration can be calculated based on the required heat and the heating power of the heating container, while also considering the time and efficiency of waste heat recovery. To improve heating efficiency and uniformity, the heating power of the heating container can be adjusted appropriately to ensure that the priority heating needs are met in the shortest possible time.

[0113] S3026. Monitor changes in vehicle operating status to obtain real-time waste heat supply capacity.

[0114] Because the operating status of vehicles is constantly changing, the waste heat supply capacity also changes accordingly. In order to adjust waste heat recovery and heating strategies in a timely and accurate manner, it is necessary to monitor the vehicle's operating status in real time to obtain the real-time waste heat supply capacity.

[0115] In this step, the operating status can be monitored using sensors installed at various key locations on the vehicle. Temperature, speed, and load sensors are installed on the engine to acquire real-time information on engine temperature, speed, and load. Current, voltage, and temperature sensors are installed on the electric motor to monitor changes in its current, voltage, and temperature. Additionally, vehicle speed and acceleration sensors can be used to obtain vehicle driving status information. Alternatively, this information can be obtained directly from the vehicle's management system, control system, or operating status monitoring system.

[0116] These data are transmitted to the vehicle's control system, which can then calculate the vehicle's waste heat supply capacity in real time based on preset algorithms and models. For example, based on engine temperature, speed, and load information, the heat generated by the engine under its current condition can be calculated using empirical formulas or machine learning models, thereby obtaining the engine's waste heat supply capacity.

[0117] By monitoring changes in vehicle operating status in real time, changes in waste heat supply capacity can be detected promptly. When the vehicle's driving conditions change, such as transitioning from congested urban traffic to highway driving, the engine's operating status will change, and the waste heat supply capacity will change accordingly. At this time, the control system can adjust the waste heat recovery and heating strategies in a timely manner to make full use of the waste heat generated by the vehicle.

[0118] S3027. When the real-time waste heat supply capacity is greater than or equal to the demand of the non-priority heating demand, adjust the waste heat recovery parameters and heating parameters to cover the non-priority heating demand.

[0119] During real-time monitoring of vehicle operating status changes, if the real-time waste heat supply capacity is found to be greater than or equal to the demand of non-priority heating components, it indicates that the waste heat generated by the vehicle is sufficient to meet the non-priority heating needs. At this point, waste heat recovery and heating parameters can be adjusted to cover the non-priority heating demand.

[0120] Regarding adjusting waste heat recovery parameters, the scope and flow rate of waste heat recovery can be appropriately expanded. If waste heat recovery was previously only performed in a certain part of the engine, it is advisable to consider adding waste heat recovery to other parts to obtain more waste heat. At the same time, increasing the flow rate of waste heat recovery and accelerating the recovery speed can more quickly meet the needs of non-priority heating components.

[0121] Heating parameters need to be reset based on the characteristics of non-priority heating needs. Adjust the heating temperature setting and heating duration of the heating container to meet the heating requirements of the non-priority materials. For example, if the non-priority heating need is for heating bread, the heating temperature can be set to a suitable temperature for bread heating, and the appropriate heating duration can be determined based on the quantity and characteristics of the bread. Simultaneously, the heating power of the heating container can be adjusted appropriately based on the availability of residual heat to improve heating efficiency.

[0122] The method provided in this application determines the waste heat supply capacity based on the vehicle's operating status, and then determines the waste heat recovery parameters and heating parameters in conjunction with the user's heating needs. When the waste heat supply capacity and heating needs do not match, the user's heating needs are reasonably divided and dynamically adjusted to achieve efficient utilization of the vehicle's waste heat. This reduces the vehicle's overall energy consumption and improves energy utilization efficiency while meeting the diverse heating needs of users.

[0123] Figure 4 This is a schematic flowchart illustrating another method for recovering and utilizing waste heat from a vehicle, provided as an embodiment of this application. Figure 4 As shown, the method may further include:

[0124] S401. Obtain the user's historical heating behavior records.

[0125] During vehicle use, the user's heating behavior is recorded. These records can be stored in the vehicle's local database or uploaded to a cloud server. Accessing the user's historical heating behavior records can be achieved in several ways. The vehicle's infotainment system can provide a data interface, allowing the reading of the user's historical heating behavior records from the local database. Alternatively, a communication connection can be established with a cloud server to download the user's historical heating behavior records from the cloud server.

[0126] Historical heating behavior records can contain a wealth of information, such as heating time, types of food being heated, heating temperature settings, and heating duration. This information can reflect users' heating habits and preferences. Users may have a habit of heating drinking water at specific times each day, or frequently heating food while traveling long distances. Obtaining these historical heating behavior records can provide important data support for predicting future heating needs.

[0127] S402. Extract heating time features and heating temperature features from historical heating behavior records.

[0128] Among them, the heating time characteristics are related to the start time and heating duration of historical heating behavior.

[0129] In this step, heating time features can be extracted by analyzing the start time and heating duration of historical heating behaviors. The start time of historical heating behaviors can be categorized into different time periods, such as morning, noon, and evening. The number of heating behaviors within each time period is counted to analyze the user's heating frequency in different time periods. Simultaneously, the distribution of heating duration is analyzed to understand the typical heating time required by users in different heating scenarios. For example, a user might only need a short time to heat a cup of water in the morning, while they might need a longer time to heat a dinner in the evening.

[0130] Heating temperature characteristics can be extracted by analyzing temperature settings in historical heating behavior. Statistical analysis of heating temperature settings for different consumer goods reveals user preferences for heating temperatures of various consumer goods. For drinking water, users may typically heat it to a specific temperature range; for food, different types of food may have different heating temperature requirements.

[0131] By extracting heating time and heating temperature characteristics, we can gain a deeper understanding of users' heating habits and needs, providing a more accurate basis for subsequent heating demand prediction.

[0132] S403. Based on the heating time characteristics and heating temperature characteristics, obtain the user's heating demand prediction results.

[0133] After extracting heating time and temperature features, these features can be used to predict user heating needs. For example, a machine learning algorithm can be used to build a heating demand prediction model. Then, the heating time and temperature features are used as input data and fed into the prediction model. Based on this input data, the prediction model can learn user heating behavior patterns and demand patterns. During training, a large amount of historical heating behavior records are used as training data, and the model parameters are continuously adjusted to enable the heating demand prediction model to accurately predict user heating needs.

[0134] Heating demand forecasting models can output predictions of a user's heating needs over a future time period. These predictions can include information such as the types of household items to be heated, the desired heating temperature, and the heating time. For example, based on a user's historical heating behavior patterns, the model can predict that the user is likely to heat a cup of water within a specific timeframe, with a desired water temperature of a particular value.

[0135] By obtaining the predicted heating demand results from users, preparations for waste heat recovery and heating can be made in advance, thereby improving the efficiency of waste heat utilization and user satisfaction.

[0136] S404. Determine the user's heating needs based on the heating demand forecast results.

[0137] After obtaining the user's heating demand forecast results, the user's heating demand can be determined based on these results.

[0138] The prediction result is only based on historical data, and actual user heating needs may be affected by various factors. Therefore, the prediction result can be further analyzed and verified. It can be corrected and adjusted by combining information such as the current vehicle operating status, external ambient temperature, and real-time user operations. If the current external ambient temperature is low, the user may have a higher heating demand; or if the user performs a new heating operation on the vehicle's infotainment system, the heating demand needs to be updated based on this real-time information.

[0139] Once the user's heating needs are determined, they can serve as the basis for subsequently determining waste heat recovery parameters and heating parameters, ensuring that the user's actual needs are better met.

[0140] The method provided in this application obtains the user's historical heating behavior records, extracts heating time features and heating temperature features from them, uses these features to obtain the user's heating demand prediction results, and then determines the user's heating needs, so as to plan and adjust the waste heat recovery and heating strategy in advance, thereby improving the accuracy and efficiency of waste heat utilization and better meeting the user's personalized heating needs.

[0141] Optionally, user heating requests can also be input via the vehicle's infotainment system. In this implementation, users can directly input their heating requests through the vehicle's infotainment system. The system provides an interactive interface where users can select the type of food to be heated, input the desired heating temperature, and set the heating time. After receiving the user's heating request information, the system transmits it to the vehicle's control system. The control system, based on this information and the vehicle's operating status and waste heat supply capacity, determines the appropriate waste heat recovery and heating parameters. For example, if a user selects to heat a cup of water and sets the desired temperature on the infotainment system, this information is sent to the control system. The control system then determines the appropriate waste heat recovery location, recovery flow rate, heating temperature setting for the heating container, and heating duration based on the vehicle's current operating status and waste heat supply.

[0142] Optionally, users can also send their heating requests via a third-party device connected to the vehicle's infotainment system. In this implementation, users can connect to the vehicle's infotainment system using a smartphone, tablet, or other third-party device. Through an application on the third-party device, users can easily input their heating request information. The third-party device can then transmit this information to the vehicle's infotainment system via wireless communication methods such as Bluetooth or Wi-Fi. Upon receiving the information, the infotainment system transmits it to the vehicle's control system, which then processes and makes corresponding decisions based on this information. For example, a user can open the relevant vehicle application on their smartphone, input their heating request for a food item, and set the heating temperature and time. The smartphone sends this information to the infotainment system, which then transmits it to the control system. The control system determines the parameters for waste heat recovery and heating based on the vehicle's actual conditions.

[0143] Figure 5 This is a schematic flowchart illustrating another method for recovering and utilizing waste heat from a vehicle, provided as an embodiment of this application. Figure 5 As shown, the method may further include:

[0144] S501, Prioritize the user's heating needs and other waste heat heating needs of the vehicle.

[0145] Other waste heat heating needs include at least one of the following: warm air heating needs, steering wheel heating needs, and seat heating needs.

[0146] During vehicle use, in addition to the user's heating needs for daily necessities, there are other waste heat heating needs, such as heater needs, steering wheel heating needs, and seat heating needs. To allocate waste heat resources rationally, it is necessary to prioritize these different heating needs.

[0147] In this step, priorities can be determined in several ways. Priorities can be determined based on user settings. For example, a vehicle's infotainment system can provide a priority setting interface, allowing users to prioritize different heating needs according to their needs and preferences. Users could set the heating of household items as the highest priority and the steering wheel heating as a lower priority.

[0148] Alternatively, priorities can be automatically determined based on the vehicle's operating status and external environmental conditions. In cold weather, the need for heating may be automatically set to a higher priority to ensure comfort inside the vehicle; while during vehicle operation, the needs for steering wheel heating and seat heating may be dynamically adjusted according to the driver's operating habits and needs.

[0149] By prioritizing user heating needs and other waste heat heating needs of vehicles, important data can be allocated for subsequent heat distribution.

[0150] S502. Determine the heat distribution strategy for waste heat based on priority.

[0151] After obtaining the priorities of different heating needs, it is necessary to determine the waste heat allocation strategy based on these priorities.

[0152] If a user's heating needs are of high priority, their heating requirements for living materials should be met first. Sufficient heat can be allocated from the vehicle's waste heat to the heating container based on the magnitude of the user's heating demand, ensuring that the living materials reach the desired heating temperature within the specified time.

[0153] For other residual heat heating needs, the remaining heat is allocated sequentially according to their priority. If the need for warm air heating is of lower priority, some residual heat can be allocated to the heating system after the user's heating needs are met to increase the temperature inside the vehicle. If the needs for steering wheel heating and seat heating are of lower priority, a small amount of heat can be allocated appropriately to meet these needs based on the remaining residual heat.

[0154] When determining a heat distribution strategy, the vehicle's waste heat supply capacity and heating efficiency must also be considered. If the waste heat supply capacity is limited, heat needs to be distributed more rationally to avoid situations where one heating demand consumes excessive heat, leaving other heating demands unmet. Simultaneously, it is crucial to ensure that the heating efficiency of each heating system reaches its optimal state during the heat distribution process to improve waste heat utilization efficiency.

[0155] S503. Based on the heat distribution strategy, determine the amount of waste heat resources to be used for heating the container.

[0156] Once the waste heat allocation strategy is determined, the amount of waste heat resources to be used for heating the container can be determined based on that strategy.

[0157] First, the amount of heat required by the heating container can be calculated based on the user's heating needs and desired heating effect. Then, combined with a heat allocation strategy, it can be determined how much waste heat resources can be allocated to the heating container while still meeting other waste heat heating needs.

[0158] If a user's heating needs are of high priority and the waste heat supply capacity is sufficient, more waste heat resources can be allocated to the heating containers to ensure that household materials can be heated quickly and effectively. If the waste heat supply capacity is limited, or other waste heat heating needs are also of high priority, it may be necessary to appropriately reduce the amount of waste heat resources allocated to the heating containers, but it must be ensured that the user's basic heating needs are met.

[0159] By determining the amount of waste heat resources used to heat the container, the utilization of waste heat can be controlled more precisely, improving the efficiency of waste heat recovery and heating, while meeting the heating needs of users and other aspects of the vehicle.

[0160] The method provided in this application obtains the priority of user heating needs and other waste heat heating needs of the vehicle, determines the heat distribution strategy of waste heat according to the priority, and then determines the amount of waste heat resources used for heating containers, so as to achieve reasonable allocation and efficient utilization of waste heat resources, thereby improving the overall energy utilization efficiency of the vehicle and the user experience while meeting the diverse heating needs of users.

Based on the urgency characteristics, the user's heating demand is divided into a priority heating demand portion and a non-priority heating demand portion. Based on the heating demand and waste heat supply capacity of the priority heating demand portion, the corresponding waste heat recovery parameters and heating parameters are determined. Changes in the vehicle's operating status are monitored to obtain the real-time waste heat supply capacity. When the real-time waste heat supply capacity is greater than or equal to the demand of the non-priority heating demand portion, the waste heat recovery parameters and heating parameters are adjusted to cover the non-priority heating demand portion.

[0168] Optionally, the acquisition module 14 is used to acquire the user's historical heating behavior records. The processing module 11 is further used to extract heating time features and heating temperature features from the historical heating behavior records. Based on the heating time features and heating temperature features, the user's heating demand prediction result is obtained. Based on the heating demand prediction result, the user's heating demand is determined. Among them, the heating time feature is related to the start time and heating duration of the historical heating behavior.
