Description

Technical Field

[0001] The present disclosure relates to the field of vehicles, and more particularly, to a method, an apparatus, and a computer-readable storage medium for thermal management of a vehicle. Background Art

[0002] With the increasing popularity of vehicles, especially new energy electric vehicles, the importance of thermal management of vehicles has become increasingly prominent. Improving the efficiency of thermal management of vehicles will directly affect the actual use process of vehicle users, especially the energy consumption and endurance performance of vehicles in high and low temperature environments.

[0003] Existing vehicle thermal management technologies, such as battery heating and cooling, and cockpit temperature control, are all based on heat control of input temperature. The main parameters considered include, for example, the temperature of the battery cell, the ambient temperature, and the set cockpit temperature. In addition, the targets for heat control of each component are fixed, and the actual application scenarios of the user are not taken into account, which will cause additional energy consumption and waste in some scenarios. Taking the cooling of high-voltage batteries for new energy vehicles as an example, from the perspective of service life, the cell temperature of the ternary lithium battery usually needs to be controlled between 25°C and 35°C. Once the cell temperature rises and reaches the threshold, it will trigger the cooling of the battery, so that the battery will be cooled directly towards the set target temperature (such as 25°C). However, this target temperature does not take into account the impact of specific application scenarios such as the distance and time that the user is expected to travel when using the vehicle, as well as external environmental factors, resulting in the following situation often occurring: the user arrives at the destination and stops using the vehicle during or after the battery cooling process. If the ambient temperature is higher than the set cooling target temperature, the battery cell temperature will gradually return to the ambient temperature, resulting in part of the energy consumed by the vehicle's thermal management during the battery cooling process being wasted, causing unnecessary energy consumption.

[0004] Therefore, there is a need for a vehicle thermal management technology that can timely and effectively manage vehicle thermal performance and minimize excessive energy consumption. Summary of the invention

[0017] In order to enable those skilled in the art to better understand the present disclosure, the present disclosure is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0018] Figure 1 A flow chart of a method 100 for thermal management of a vehicle according to an embodiment of the present invention is shown. Figure 1 A method for thermal management of a vehicle according to an embodiment of the present invention is described. The thermal management component targeted by the thermal management method for a vehicle according to an embodiment of the present invention may be any component of the vehicle, in particular, a component in the vehicle that is sensitive to temperature or a component whose performance is easily affected by temperature. For example, the thermal management component of the vehicle in an embodiment of the present invention may be various components such as the vehicle's power battery (high-voltage battery), the vehicle's cockpit, and the vehicle's engine, which are not limited here.

[0019] In step S101 , it is determined whether the vehicle driving mode meets the requirements of the thermal management mode according to the vehicle navigation data and / or the vehicle driving state.

[0020] In one example, when the vehicle navigation data can be obtained, it is possible to directly obtain various information such as the departure point, destination, driving trajectory, traffic conditions, etc. of the vehicle through the vehicle navigation data to further estimate the remaining driving distance and / or remaining driving time of the vehicle to the destination. Therefore, in this case, when the remaining driving distance and / or remaining driving time of the vehicle can be estimated based on the vehicle navigation data, it can be determined that the vehicle driving mode meets the requirements of the thermal management mode.

[0021] In another example, whether the vehicle driving mode meets the requirements of the thermal management mode can also be determined by constructing a fixed driving trajectory model of the vehicle. Optionally, one or more fixed driving trajectories of the vehicle can be obtained based on an analysis of multiple historical driving trajectories of the vehicle, and the fixed driving trajectory model of the vehicle can be constructed using the one or more fixed driving trajectories.

[0022] Optionally, based on the analysis of the multiple historical driving trajectories of the vehicle, obtaining one or more fixed driving trajectories of the vehicle may include: comparing the starting points, end points and / or driving trajectories of the multiple historical driving trajectories, and when the comparison result shows that the similarity of at least two of the historical driving trajectories exceeds a similarity threshold, obtaining the fixed driving trajectory according to the at least two historical driving trajectories. For example, when the departure place and the destination of at least two of the historical driving trajectories are the same or the distance is within a certain range, it can be considered that the similarity of the at least two historical driving trajectories exceeds the similarity threshold. For another example, when the departure place and the destination of at least two historical driving trajectories are opposite, that is, the departure place of one historical driving trajectory is the destination of another historical driving trajectory, and the destination of the historical driving trajectory is the departure place of the other historical driving trajectory, it can also be considered that the similarity of the at least two historical driving trajectories exceeds the similarity threshold. In addition, optionally, when the departure points and destinations of at least two historical driving trajectories are the same, opposite, or the distance between them is within a certain range, the specific driving trajectories between these historical driving trajectories can be further compared. For example, the longitude and latitude two-dimensional vectors of these trajectories can be drawn respectively according to the longitude and latitude data, and the similarity between the longitude and latitude two-dimensional vectors corresponding to these trajectories can be calculated (for example, cosine similarity can be calculated), so as to obtain a fixed driving trajectory based on the historical driving trajectories with higher similarity.

[0023] When the fixed driving trajectory is obtained according to the at least two historical driving trajectories, optionally, the at least two historical driving trajectories can be averaged or weighted averaged, and the processing result can be used as the fixed driving trajectory of the vehicle. After obtaining one or more fixed driving trajectories of the vehicle, a corresponding fixed driving trajectory model of the vehicle can be constructed for each of the one or more fixed driving trajectories. In addition, after obtaining one or more fixed driving trajectories, the fixed driving trajectory can be stored and used as a fixed driving trajectory model of the vehicle to be compared with the current driving trajectory of the vehicle. For example, the information of the fixed driving trajectory of the vehicle in the stored fixed driving trajectory model may include: the departure place, destination, driving trajectory, departure time, arrival time, driving time, driving distance, driving date (or week information, such as working days in a week, Saturday / Sunday in a week, etc.), one or more information in longitude and latitude data of the vehicle. In addition, when the vehicle can identify the user by, for example, user login, optionally, the fixed form trajectory model of the vehicle can also be classified according to the different users of the vehicle, and compared with the driving trajectories of the corresponding users respectively. Furthermore, the fixed driving trajectory model of the vehicle can be iterated and updated accordingly according to the continuous updating of the vehicle's driving trajectory.

[0024] In one example of the present invention, the fixed driving trajectory model of the vehicle may include a commuting trajectory model of the user from home to work or from work to home. In addition, in another example, the fixed driving trajectory model of the vehicle may also include a pick-up trajectory model of the user from home to the child's school or from the child's school to home. In yet another example, the fixed driving trajectory model of the vehicle may also include a periodic trajectory model of the user from place A to place B on certain specific dates, etc. The selection and judgment of the departure place, destination and driving trajectory of the fixed driving trajectory model of the vehicle can be screened and judged according to the historical driving trajectory of the vehicle and the different usage habits of the user for the vehicle, and there is no limitation here.

[0025] After constructing the fixed driving trajectory model of the vehicle, the vehicle navigation data and / or the vehicle driving state can be compared with one or more fixed driving trajectories included in the fixed driving trajectory model of the vehicle. Optionally, the departure place, destination, departure time, driving trajectory, etc. of the vehicle obtained according to the vehicle navigation data can be compared with one or more fixed driving trajectories included in the fixed driving trajectory model of the vehicle. In addition, optionally, the departure place, departure time, current driving trajectory and / or expected destination of the vehicle obtained according to the vehicle driving state can also be compared with one or more fixed driving trajectories included in the fixed driving trajectory model of the vehicle. For example, the latitude and longitude data of the current driving trajectory of the vehicle can be compared with the latitude and longitude data of each fixed driving trajectory in the fixed driving trajectory model of the vehicle, and the cosine similarity can be calculated to obtain the result of the possibility that the vehicle driving mode conforms to one of the fixed driving trajectories in the fixed driving trajectory model. Subsequently, when the comparison result shows that the possibility that the vehicle driving mode conforms to any fixed driving trajectory in the fixed driving trajectory model of the vehicle exceeds the possibility threshold, it is judged that the vehicle driving mode meets the requirements of the thermal management mode.

[0026] The above method of using vehicle navigation data and / or vehicle driving status to determine whether the vehicle driving mode meets the requirements of the thermal management mode is only an example. In actual application, the determination method of the thermal management mode can be flexibly adjusted according to the specific driving scenario of the vehicle and the specific requirements of the thermal management mode of the vehicle, and there is no limitation here.

[0027] In step S102, when it is determined that the vehicle driving mode meets the requirements of the thermal management mode, the ambient temperature and the upper and lower temperature limits of the thermal management components in the thermal management mode are obtained, and the remaining driving distance and / or remaining driving time of the vehicle to the destination are estimated.

[0028] Optionally, when it is determined that the vehicle driving mode meets the requirements of the thermal management mode, the remaining driving distance and / or remaining driving time of the vehicle can be estimated based on various information such as the vehicle's departure point, destination, driving trajectory, traffic conditions, etc. obtained from the vehicle navigation data.

[0029] In addition, optionally, when the vehicle navigation data and / or the vehicle driving state conform to the fixed driving trajectory model of the vehicle, the remaining driving distance and / or remaining driving time of the vehicle can be estimated based on the fixed driving trajectory of the vehicle that is consistent with the vehicle navigation data and / or the vehicle driving state.

[0030] The above method of estimating the remaining driving distance and / or remaining driving time of the vehicle by using the vehicle navigation data and / or the vehicle driving status is only an example. In actual application, the estimation method of the remaining driving distance and / or remaining driving time of the vehicle can be flexibly adjusted according to the specific driving scene of the vehicle and the specific requirements of the thermal management mode of the vehicle, and there is no limitation here.

[0031] In step S103, thermal management is performed on the thermal management component of the vehicle according to the acquired ambient temperature, the upper temperature limit and the lower temperature limit of the thermal management component, and in combination with the estimated remaining driving distance and / or remaining driving time.

[0032] Optionally, a specific thermal management method of the vehicle may be determined according to a specific type of thermal management components of the vehicle.

[0033] In one example, based on the acquired ambient temperature, the upper temperature limit and the lower temperature limit of the thermal management component, and in combination with the estimated remaining driving distance and / or the remaining driving time, thermal management of the thermal management component of the vehicle may include: thermally managing the thermal management component by adjusting the upper temperature limit and / or the lower temperature limit of the thermal management component based on the relationship between the ambient temperature and the upper temperature limit and / or the lower temperature limit of the thermal management component.

[0034] For example, when the ambient temperature T amb Greater than the upper temperature limit T of the thermal management component H When the lower limit temperature T of the thermal management component is further combined L , according to the conventional thermal management component temperature cooling range [T H , T L ] Cool the temperature T of the thermal management component. That is, when the temperature T of the thermal management component is higher than the upper temperature limit T of the thermal management component H When T=T L When the cooling is stopped, the cooling power during thermal management can be adjusted according to T and T L The deviation between them is used for PID calculation to adjust the cooling speed of the thermal management component.

[0035] For example, when the ambient temperature T amb Less than or equal to the upper temperature limit T of the thermal management component H , and is greater than or equal to the lower temperature limit T of the thermal management component L When the lower limit temperature T of the thermal management component is adjusted, L , so that T L =T amb , in order to reduce the cooling power during thermal management and save energy consumption.

[0036] For example, when the ambient temperature Tamb Less than the lower temperature limit T of the thermal management component L When the upper temperature limit T of the thermal management component is H and the lower temperature limit T of the thermal management component L Adjust to be equal so that T H =T L , so that when the temperature T of the thermal management component reaches the upper temperature limit T of the thermal management component H Active cooling is stopped at this time, and the ambient temperature is fully utilized to continue cooling, thereby further saving energy consumption.

[0037] In addition, further, on the basis of the above thermal management optimization, the specific method of thermal management can be further adjusted in combination with the estimated remaining driving distance and / or remaining driving time. Optionally, based on the acquired ambient temperature, the upper and lower temperature limits of the thermal management components, and in combination with the estimated remaining driving distance and / or remaining driving time, thermal management of the thermal management components of the vehicle can also include: when the estimated remaining driving distance is less than a preset distance threshold, and / or the remaining driving time is less than a preset time threshold, further adjusting the upper and / or lower temperature limits of the thermal management components, and thermally managing the thermal management components.

[0038] In one example, when the ambient temperature T amb Greater than the upper temperature limit T of the thermal management component H When the estimated remaining driving distance d is less than a preset distance threshold D0 (e.g., 5 km), and / or the remaining driving time t is less than a preset time threshold T0 (e.g., 30 minutes), the lower limit temperature T of the thermal management component can be further increased on the basis of the above. L , for example, so that T L =T H , so that when the temperature T of the thermal management component is higher than the upper temperature limit T of the thermal management component H When the temperature T of the thermal management component is lower than the upper temperature limit T of the thermal management component, the cooling power of the thermal management component is reduced to reduce energy consumption; H When the temperature of the thermal management component after cooling deviates too much from the ambient temperature, the active cooling is stopped to reduce the energy waste caused by the heating of the thermal management component after reaching the destination.

[0039] In another example, when the ambient temperature T amb Less than or equal to the upper temperature limit T of the thermal management component H and is greater than or equal to the lower temperature limit T of the thermal management component L When adjusting the lower limit temperature T of the thermal management component L Make T L =T ambOn the basis of the estimated remaining driving distance d being less than a preset distance threshold D1 (e.g., 10 km), and / or the remaining driving time t being less than a preset time threshold T1 (e.g., 1 hour), the lower limit temperature T of the thermal management component may be further increased. L , for example, so that T L =T H , so that when the temperature T of the thermal management component is reduced to below the upper temperature limit T of the thermal management component H When active cooling is stopped, the energy consumption caused by thermal management can be further reduced.

[0040] In addition, as mentioned above, different thermal management methods can also be used according to the specific type of thermal management components. For example, when the thermal management component is a power battery of a vehicle, the thermal management method described above can be used for cooling. However, when the thermal management component is a cockpit, other specific thermal management methods can be used. For example, when the estimated remaining driving distance d is less than a preset distance threshold D2 (e.g., 3 km), and / or the remaining driving time t is less than a preset time threshold T2 (e.g., 20 minutes), the temperature T set for the air conditioner in the cockpit is expressed as:

[0041] T=T s ±k(D2-d) (1)

[0042] Among them, T s is the set temperature of the cockpit. k is the temperature variation coefficient, indicating that the cockpit air conditioning set temperature is adjusted to rise / fall k degrees Celsius per kilometer when the distance to the destination is close, and its unit is ℃ / km. In one example, k can take a value of 0.3-0.5. In formula (1), when the cockpit air conditioning is set to cooling, the sign can be "+", and when the cockpit air conditioning is set to cooling, the sign can be "-".

[0043] The above-mentioned specific thermal management methods for the relationship between the various temperatures, the remaining driving distance / time, and the different thermal management component types are only examples. In actual applications, any corresponding thermal management method can be adopted according to the actual application scenario, and there is no limitation here. In addition, the above-mentioned comparison relationship between the various temperatures of greater than or less than can also include the case where the temperatures are equal, and there is no limitation here.

[0044] According to the vehicle thermal management method of an embodiment of the present invention, it is possible to determine whether the vehicle complies with the thermal management mode by judging the vehicle driving mode. In the thermal management mode, the thermal management method of the vehicle can be flexibly adjusted by combining the ambient temperature, the remaining driving distance of the vehicle and / or the driving time, thereby reducing energy consumption and improving the efficiency of vehicle thermal management.

[0045] A specific example of a method for thermal management of a vehicle according to an embodiment of the present invention is provided below. In the example of the embodiment of the present invention, thermal management can be performed on the power battery (high voltage battery) of the vehicle as a thermal management component of the vehicle, and the thermal management mode of the vehicle can be judged in combination with the commuting trajectory model of the vehicle as a fixed driving trajectory model of the vehicle. Figure 2 An example of the hardware structure of a vehicle controller according to an example of an embodiment of the present invention is shown. In this example, the vehicle can Figure 2 The vehicle energy control module in the vehicle controller performs commuting mode recognition based on the commuting trajectory model, and uses the thermal management control module to perform thermal management of the vehicle's power battery. In addition, when thermal management of the vehicle's cockpit is required, the air conditioning control module in the vehicle controller can also be used to perform thermal management of the cockpit's air conditioning.

[0046] Specifically, firstly, it can be determined whether the vehicle driving mode meets the requirements of the thermal management mode according to the vehicle navigation data and / or the vehicle driving status.

[0047] In this example, when it is determined that the vehicle's driving mode meets the vehicle's commuting mode based on the vehicle navigation data and / or the vehicle's driving state, it can be determined that the vehicle meets the requirements of the thermal management mode. That is, when the vehicle's driving mode meets the commuting mode, the vehicle's power battery can be thermally managed according to the thermal management mode.

[0048] Considering that the vehicle's commuting mode has some inherent properties compared to other travel modes, for example, the departure time and arrival time in the commuting mode are relatively similar, and the driving trajectory in the commuting mode is generally consistent, therefore, in this example, the following methods can be used to determine whether the vehicle meets the commuting mode.

[0049] Optionally, it is possible to determine whether the commuting mode is met based on the vehicle navigation data input by the user through the navigation unit in the vehicle controller. For example, the navigation path triggered by the user by clicking on the tag or voice control can be obtained through tags formed by common addresses such as "home" and "company" pre-stored by the user in the navigation unit to determine whether the vehicle is traveling in commuting mode. In addition, the user's position when the navigation path is triggered can be obtained in combination with the GPS signal obtained through the antenna network unit of the vehicle controller to determine whether the navigation path triggered by the user is a driving path from "home" to "company" or from "company" to "home", thereby knowing whether the vehicle's driving meets the commuting mode.

[0050] In addition, optionally, it is also possible to determine whether the vehicle's driving mode is a commuting mode by constructing a commuting trajectory model of the vehicle. In this example, a commuting trajectory model of the vehicle can be constructed first. Specifically, the vehicle's latitude and longitude information, vehicle speed information, and vehicle travel distance (for example, calculated based on the integral of vehicle speed over time) can be recorded for the driving cycle of the vehicle from the start of driving to locking the vehicle in historical situations at a fixed time period (collection time interval is, for example, 1s, and collection frequency is, for example, 1Hz), and stored in the vehicle controller in the following table format.

[0051]

[0052] Table 1. Data related to vehicle historical driving trajectory

[0053] Table 1 shows the relevant data of the above-mentioned vehicle's historical driving trajectory. In Table 1, the latitude and longitude information, speed information and driving distance of the vehicle are recorded at 1s time intervals from the start of driving to locking the vehicle. Some specific data contents are omitted in the table and are not shown.

[0054] After collecting data of multiple historical driving trajectories as shown in the data in Table 1, a commuting trajectory model of the vehicle can be constructed accordingly. First, the corresponding longitude and latitude data in all tables can be retrieved according to the departure and / or destination data of the vehicle, and irrelevant driving cycle data can be eliminated, and the historical driving trajectory data with a high probability of overlap (such as overlap between departure and departure, overlap between destination and destination, and overlap between departure and destination) can be selected.

[0055] Subsequently, a historical driving track curve may be drawn based on the latitude and longitude data of the historical driving track in the selected table, with longitude as the X-axis and latitude as the Y-axis. Figure 3 A schematic diagram of a historical driving trajectory curve according to an example of an embodiment of the present invention is shown. Figure 3 In the figure, the latitude and longitude data of the vehicle obtained through each sampling point represents the two-dimensional vector of the vehicle's historical driving trajectory.

[0056] By comparing the two-dimensional vectors of longitude and latitude of these historical driving trajectories, for example, by calculating the cosine similarity, two historical driving trajectory curves with the highest similarity between the historical driving trajectories can be obtained as the user's commuting trajectory.

[0057] Afterwards, the filtered commuting trajectories can be reversely searched for the corresponding stored table latitude and longitude data, as shown in Tables 2 and 3 below, as the user's commuting trajectory model.

[0058]

[0059] Table 2. Data related to home and company in the commuting trajectory model

[0060]

[0061] Table 3. Company-home related data in the commuting trajectory model

[0062] Tables 2 and 3 show the latitude and longitude location information of the home and company, daily commuting one-way distance, daily commuting one-way time and other information in the commuting trajectory model. The specific data in the commuting trajectory model in Tables 2 and 3 can be the data of one of the historical commuting trajectories, or the average or weighted average of multiple historical commuting trajectory data, which are not limited here. In addition, the vehicle's commuting trajectory model can be iterated and updated accordingly according to the continuous update of the vehicle's commuting trajectory.

[0063] After constructing the commuting trajectory model of the vehicle, the current driving trajectory of the vehicle can be compared with the commuting trajectory model. Optionally, the departure place, destination, departure time, driving trajectory, etc. of the vehicle obtained according to the vehicle navigation data can be compared with the commuting trajectory model of the vehicle. In addition, optionally, the departure place, departure time, current driving trajectory and / or expected destination of the vehicle obtained according to the driving state of the vehicle can also be compared with the commuting trajectory model of the vehicle. For example, the latitude and longitude positions of the departure place and / or destination of the vehicle's current driving trajectory can be compared with the commuting trajectory model, and the departure time of the vehicle can be referred to whether it is within the range of the commuting time. Subsequently, the latitude and longitude data of the current driving trajectory of the vehicle can be compared with the latitude and longitude data of each commuting trajectory in the commuting trajectory model of the vehicle, and the cosine similarity can be calculated to determine whether the current vehicle driving trajectory conforms to the commuting trajectory model, and output the possibility that the current vehicle driving trajectory conforms to the commuting trajectory model. When the possibility exceeds the possibility threshold, it is determined that the vehicle driving mode conforms to the commuting trajectory model, and the thermal management mode can be used to thermally manage the power battery of the vehicle.

[0064] In subsequent steps, when it is determined that the vehicle driving mode meets the requirements of the thermal management mode, the ambient temperature and the upper and lower temperature limits of the thermal management components in the thermal management mode are obtained, and the remaining driving distance and / or remaining driving time of the vehicle to the destination are estimated.

[0065] Optionally, when it is determined that the vehicle driving mode meets the requirements of the thermal management mode, the vehicle's remaining driving distance can be estimated by using the expected total driving distance and the current driving distance based on various information such as the vehicle's departure point, destination, driving trajectory, traffic conditions, etc. obtained from the vehicle navigation data, and the vehicle's remaining driving time can be estimated by using the expected total driving time and the current driving time.

[0066] Finally, the power battery of the vehicle may be thermally managed according to the acquired ambient temperature, the upper and lower temperature limits of the power battery, and in combination with the estimated remaining driving distance and / or remaining driving time.

[0067] In one example, the thermal management component can be thermally managed by adjusting the upper and / or lower temperature limits of the power battery according to the relationship between the ambient temperature and the upper and / or lower temperature limits of the power battery. In addition, further, on the basis of the above thermal management optimization, the specific method of thermal management can be further adjusted in combination with the estimated remaining driving distance and / or remaining driving time. When the estimated remaining driving distance is less than a preset distance threshold, and / or the remaining driving time is less than a preset time threshold, the upper and / or lower temperature limits of the power battery can be further adjusted to perform fine thermal management on the power battery.

[0068] For example, when the ambient temperature T amb Greater than the upper temperature limit T of the power battery H When the lower limit of the temperature of the power battery is T L According to the conventional power battery temperature cooling range [T H , T L ] to cool the temperature T of the power battery. That is, when the temperature T of the power battery is higher than the upper temperature limit T of the thermal management component H When T=T L When the cooling is stopped, the cooling power during thermal management can be adjusted according to T and T L PID calculation is performed based on the deviation between the two values ​​to adjust the cooling speed of the power battery. On this basis, when the estimated remaining driving distance d is less than the preset distance threshold D0 (e.g., 5 km), and / or the remaining driving time t is less than the preset time threshold T0 (e.g., 30 minutes), the lower limit of the temperature T of the power battery can be further increased on the basis of the above. L , for example, so that T L =T H , so that when the temperature T of the power battery is higher than the upper temperature limit T of the power battery H When the temperature T of the power battery is reduced to below the upper temperature limit T of the power battery, the cooling power of the thermal management is reduced to reduce energy consumption; H When the vehicle reaches the destination, active cooling is stopped to avoid a large deviation between the temperature of the cooled power battery and the ambient temperature, thereby reducing energy waste caused by the power battery heating up after reaching the destination.

[0069] For example, when the ambient temperature T amb Less than or equal to the upper temperature limit T of the power battery H , and is greater than or equal to the lower temperature limit T of the power battery LWhen the lower limit of the battery temperature T is adjusted, L , so that T L =T amb , in order to reduce the cooling power during thermal management and save energy consumption. On this basis, when the estimated remaining driving distance d is less than the preset distance threshold D1 (for example, 10 km), and / or the remaining driving time t is less than the preset time threshold T1 (for example, 1 hour), the lower limit of the temperature of the power battery T can be further increased. L , for example, so that T L =T H , so that when the temperature T of the power battery is reduced to below the upper temperature limit T of the power battery H When active cooling is stopped, the energy consumption caused by thermal management can be further reduced.

[0070] For example, when the ambient temperature T amb Less than the lower temperature limit T of the power battery L When the upper temperature limit T of the power battery can be H And the lower limit of the battery temperature T L Adjust to be equal so that T H =T L , so that when the temperature T of the power battery reaches the upper temperature limit T of the power battery H Active cooling is stopped at this time, and the ambient temperature is fully utilized to continue cooling, thereby further saving energy consumption.

[0071] Below, refer to Figure 4 A vehicle thermal management apparatus according to an embodiment of the present invention will be described. Figure 4 FIG. 4 is a block diagram of a vehicle thermal management device 400 according to an embodiment of the present invention. Figure 4 As shown, the vehicle thermal management device 400 includes a judgment unit 410, an acquisition unit 420, and a management unit 430. In addition to these units, the vehicle thermal management device 400 may also include other components. However, since these components are irrelevant to the content of the embodiment of the present invention, their illustration and description are omitted here. In addition, since the specific details of the following operations performed by the vehicle thermal management device 400 according to the embodiment of the present invention are the same as those described above with reference to Figure 1 The details described are the same, so repeated description of the same details is omitted here to avoid repetition.

[0072] Figure 4 The thermal management component targeted by the vehicle thermal management device 400 may be any component of the vehicle, especially a component in the vehicle that is sensitive to temperature or a component whose performance is easily affected by temperature. For example, the thermal management component of the vehicle in the embodiment of the present invention may be various components such as the vehicle's power battery (high-voltage battery), the vehicle's cockpit, and the vehicle's engine, which are not limited here.

[0073] The determination unit 410 determines whether the vehicle driving mode meets the requirements of the thermal management mode according to the vehicle navigation data and / or the vehicle driving state.

[0074] In one example, when the vehicle navigation data can be obtained, the judgment unit 410 may directly obtain various information such as the departure point, destination, driving track, traffic conditions, etc. of the vehicle through the vehicle navigation data to further estimate the remaining driving distance and / or remaining driving time of the vehicle to the destination. Therefore, in this case, when the remaining driving distance and / or remaining driving time of the vehicle can be estimated according to the vehicle navigation data, it can be judged that the vehicle driving mode meets the requirements of the thermal management mode.

[0075] In another example, the judgment unit 410 may also judge whether the vehicle driving mode meets the requirements of the thermal management mode by constructing a fixed driving trajectory model of the vehicle. Optionally, one or more fixed driving trajectories of the vehicle may be obtained based on an analysis of multiple historical driving trajectories of the vehicle, and the fixed driving trajectory model of the vehicle may be constructed using the one or more fixed driving trajectories.

[0076] Optionally, the determination unit 410 may obtain one or more fixed driving trajectories of the vehicle according to the analysis of the multiple historical driving trajectories of the vehicle, and may include: comparing the starting point, the end point and / or the driving trajectory of the multiple historical driving trajectories, and when the comparison result shows that the similarity of at least two of the historical driving trajectories exceeds the similarity threshold, obtaining the fixed driving trajectory according to the at least two historical driving trajectories. For example, when the departure place and the destination of at least two of the historical driving trajectories are the same or the distance is within a certain range, it can be considered that the similarity of the at least two historical driving trajectories exceeds the similarity threshold. For another example, when the departure place and the destination of at least two historical driving trajectories are opposite, that is, the departure place of one historical driving trajectory is the destination of another historical driving trajectory, and the destination of the historical driving trajectory is the departure place of the other historical driving trajectory, it can also be considered that the similarity of the at least two historical driving trajectories exceeds the similarity threshold. In addition, optionally, when the departure points and destinations of at least two historical driving trajectories are the same, opposite, or the distance between them is within a certain range, the specific driving trajectories between these historical driving trajectories can be further compared. For example, the longitude and latitude two-dimensional vectors of these trajectories can be drawn respectively according to the longitude and latitude data, and the similarity between the longitude and latitude two-dimensional vectors corresponding to these trajectories can be calculated (for example, cosine similarity can be calculated), so as to obtain a fixed driving trajectory based on the historical driving trajectories with higher similarity.

[0077] When the fixed driving trajectory is obtained according to the at least two historical driving trajectories, optionally, the at least two historical driving trajectories can be averaged or weighted averaged, and the processing result can be used as the fixed driving trajectory of the vehicle. After obtaining one or more fixed driving trajectories of the vehicle, a corresponding fixed driving trajectory model of the vehicle can be constructed for each of the one or more fixed driving trajectories. In addition, after obtaining one or more fixed driving trajectories, the fixed driving trajectory can be stored and used as a fixed driving trajectory model of the vehicle to be compared with the current driving trajectory of the vehicle. For example, the information of the fixed driving trajectory of the vehicle in the stored fixed driving trajectory model may include: the departure place, destination, driving trajectory, departure time, arrival time, driving time, driving distance, driving date (or week information, such as working days in a week, Saturday / Sunday in a week, etc.), one or more information in longitude and latitude data of the vehicle. In addition, when the vehicle can identify the user by, for example, user login, optionally, the fixed form trajectory model of the vehicle can also be classified according to the different users of the vehicle, and compared with the driving trajectories of the corresponding users respectively. Furthermore, the fixed driving trajectory model of the vehicle can be iterated and updated accordingly according to the continuous updating of the vehicle's driving trajectory.

[0078] In one example of the present invention, the fixed driving trajectory model of the vehicle may include a commuting trajectory model of the user from home to work or from work to home. In addition, in another example, the fixed driving trajectory model of the vehicle may also include a pick-up trajectory model of the user from home to the child's school or from the child's school to home. In yet another example, the fixed driving trajectory model of the vehicle may also include a periodic trajectory model of the user from place A to place B on certain specific dates, etc. The selection and judgment of the departure place, destination and driving trajectory of the fixed driving trajectory model of the vehicle can be screened and judged according to the historical driving trajectory of the vehicle and the different usage habits of the user for the vehicle, and there is no limitation here.

[0079] After the judgment unit 410 constructs the fixed driving trajectory model of the vehicle, the vehicle navigation data and / or the vehicle driving state can be compared with one or more fixed driving trajectories included in the fixed driving trajectory model of the vehicle. Optionally, the departure place, destination, departure time, driving trajectory, etc. of the vehicle obtained according to the vehicle navigation data can be compared with one or more fixed driving trajectories included in the fixed driving trajectory model of the vehicle. In addition, optionally, the departure place, departure time, current driving trajectory and / or expected destination of the vehicle obtained according to the vehicle driving state can also be compared with one or more fixed driving trajectories included in the fixed driving trajectory model of the vehicle. For example, the latitude and longitude data of the current driving trajectory of the vehicle can be compared with the latitude and longitude data of each fixed driving trajectory in the fixed driving trajectory model of the vehicle, and the cosine similarity can be calculated to obtain the result of the possibility that the vehicle driving mode conforms to one of the fixed driving trajectories in the fixed driving trajectory model. Subsequently, when the comparison result shows that the possibility that the vehicle driving mode conforms to any fixed driving trajectory in the fixed driving trajectory model of the vehicle exceeds the possibility threshold, it is judged that the vehicle driving mode meets the requirements of the thermal management mode.

[0080] The above method of using vehicle navigation data and / or vehicle driving status to determine whether the vehicle driving mode meets the requirements of the thermal management mode is only an example. In actual application, the determination method of the thermal management mode can be flexibly adjusted according to the specific driving scenario of the vehicle and the specific requirements of the thermal management mode of the vehicle, and there is no limitation here.

[0081] When the acquisition unit 420 determines that the vehicle driving mode meets the requirements of the thermal management mode, it acquires the ambient temperature and the upper and lower temperature limits of the thermal management components under the thermal management mode, and estimates the remaining driving distance and / or remaining driving time of the vehicle to the destination.

[0082] Optionally, when it is determined that the vehicle driving mode meets the requirements of the thermal management mode, the acquisition unit 420 can estimate the remaining driving distance and / or remaining driving time of the vehicle based on various information such as the vehicle's departure point, destination, driving trajectory, traffic conditions, etc. obtained from the vehicle navigation data.

[0083] In addition, optionally, the acquisition unit 420 can also estimate the remaining driving distance and / or remaining driving time of the vehicle based on the fixed driving trajectory of the vehicle that is consistent with the vehicle navigation data and / or the vehicle driving status when the vehicle navigation data and / or the vehicle driving status conform to the fixed driving trajectory model of the vehicle.

[0084] The above method of estimating the remaining driving distance and / or remaining driving time of the vehicle by using the vehicle navigation data and / or the vehicle driving status is only an example. In actual application, the estimation method of the remaining driving distance and / or remaining driving time of the vehicle can be flexibly adjusted according to the specific driving scene of the vehicle and the specific requirements of the thermal management mode of the vehicle, and there is no limitation here.

[0085] The management unit 430 performs thermal management on the thermal management component of the vehicle according to the acquired ambient temperature, the upper temperature limit and the lower temperature limit of the thermal management component, and in combination with the estimated remaining driving distance and / or remaining driving time.

[0086] Optionally, the management unit 430 may determine a specific thermal management method for the vehicle according to a specific type of thermal management components of the vehicle.

[0087] In one example, the management unit 430 performs thermal management on the thermal management component of the vehicle based on the acquired ambient temperature, the upper temperature limit and the lower temperature limit of the thermal management component, and in combination with the estimated remaining driving distance and / or the remaining driving time, which may include: thermally managing the thermal management component by adjusting the upper temperature limit and / or the lower temperature limit of the thermal management component based on the relationship between the ambient temperature and the upper temperature limit and / or the lower temperature limit of the thermal management component.

[0088] For example, when the ambient temperature T amb Greater than the upper temperature limit T of the thermal management component H When the management unit 430 can further combine the lower limit temperature T of the thermal management component L , according to the conventional thermal management component temperature cooling range [T H , T L ] Cool the temperature T of the thermal management component. That is, when the temperature T of the thermal management component is higher than the upper temperature limit T of the thermal management component H When T=T L When the cooling is stopped, the cooling power during thermal management can be adjusted according to T and T L The deviation between them is used for PID calculation to adjust the cooling speed of the thermal management component.

[0089] For example, when the ambient temperature T amb Less than or equal to the upper temperature limit T of the thermal management component H , and is greater than or equal to the lower temperature limit T of the thermal management component L When the management unit 430 can consider adjusting the lower limit temperature T of the thermal management component L , so that T L =T amb , in order to reduce the cooling power during thermal management and save energy consumption.

[0090] For example, when the ambient temperature T amb Less than the lower temperature limit T of the thermal management component L When the management unit 430 can set the upper temperature limit T of the thermal management component H and the lower limit temperature T of the thermal management component L Adjust to be equal so that T H =T L , so that when the temperature T of the thermal management component reaches the upper temperature limit T of the thermal management component H Active cooling is stopped at this time, and the ambient temperature is fully utilized to continue cooling, thereby further saving energy consumption.

[0091] In addition, further, based on the above thermal management optimization, the management unit 430 can also continue to adjust the specific method of thermal management in combination with the estimated remaining driving distance and / or remaining driving time. Optionally, based on the acquired ambient temperature, the upper and lower temperature limits of the thermal management components, and in combination with the estimated remaining driving distance and / or remaining driving time, thermal management of the thermal management components of the vehicle can also include: when the estimated remaining driving distance is less than a preset distance threshold, and / or the remaining driving time is less than a preset time threshold, further adjusting the upper and lower temperature limits of the thermal management components, and thermally managing the thermal management components.

[0092] In one example, when the ambient temperature T amb Greater than the upper temperature limit T of the thermal management component H When the estimated remaining driving distance d is less than a preset distance threshold D0 (e.g., 5 km), and / or the remaining driving time t is less than a preset time threshold T0 (e.g., 30 minutes), the management unit 430 can further increase the lower temperature limit T of the thermal management component on the basis of the above. L , for example, so that T L =T H , so that when the temperature T of the thermal management component is higher than the upper temperature limit T of the thermal management component H When the cooling power of thermal management is reduced to reduce energy consumption; when the temperature T of the thermal management component is reduced to below the upper temperature limit T of the thermal management component H When the temperature of the thermal management component after cooling deviates too much from the ambient temperature, the active cooling is stopped to reduce the energy waste caused by the heating of the thermal management component after reaching the destination.

[0093] In another example, when the ambient temperature T amb Less than or equal to the upper temperature limit T of the thermal management component H and is greater than or equal to the lower temperature limit T of the thermal management component L When adjusting the lower limit temperature T of the thermal management component L Make TL =T amb On the basis of the estimated remaining driving distance d being less than a preset distance threshold D1 (e.g., 10 km), and / or the remaining driving time t being less than a preset time threshold T1 (e.g., 1 hour), the management unit 430 may further increase the lower temperature limit T of the thermal management component. L , for example, so that T L =T H , so that when the temperature T of the thermal management component is lower than the upper temperature limit T of the thermal management component H When active cooling is stopped, the energy consumption caused by thermal management can be further reduced.

[0094] In addition, as mentioned above, the management unit 430 can also adopt different thermal management methods according to the specific type of thermal management components. For example, when the thermal management component is a power battery of a vehicle, the management unit 430 can adopt the thermal management method described above for cooling. However, when the thermal management component is a cockpit, the management unit 430 can adopt other specific thermal management methods. For example, when the estimated remaining driving distance d is less than a preset distance threshold D2 (e.g., 3 km), and / or the remaining driving time t is less than a preset time threshold T2 (e.g., 20 minutes), the temperature T set for the air conditioner in the cockpit is expressed as formula (1)

[0095] Among them, T s is the set temperature of the cockpit. k is the temperature variation coefficient, indicating that the cockpit air conditioning set temperature is adjusted to rise / fall k degrees Celsius per kilometer when the distance to the destination is close, and its unit is ℃ / km. In one example, k can take a value of 0.3-0.5. In formula (1), when the cockpit air conditioning is set to cooling, the sign can be "+", and when the cockpit air conditioning is set to cooling, the sign can be "-".

[0096] The above-mentioned specific thermal management methods for the relationship between the various temperatures, the remaining driving distance / time, and the different thermal management component types are only examples. In actual applications, any corresponding thermal management method can be adopted according to the actual application scenario, and there is no limitation here. In addition, the above-mentioned comparison relationship between the various temperatures of greater than or less than can also include the case where the temperatures are equal, and there is no limitation here.

[0097] The vehicle thermal management device according to an embodiment of the present invention can determine whether the vehicle meets the thermal management mode by judging the vehicle driving mode. In the thermal management mode, the thermal management method of the vehicle can be flexibly adjusted in combination with the ambient temperature, the remaining driving distance of the vehicle and / or the driving time, thereby reducing energy consumption and improving the efficiency of vehicle thermal management.
