Description

Technical Field

[0001] This invention relates to the field of vehicle technology, and more specifically, to a vehicle thermal management method and a vehicle. Background Technology

[0002] Currently, with the booming development of new energy vehicles, thermal management systems have become increasingly complex, encompassing not only engine thermal management and passenger compartment thermal management, but also battery thermal management, motor thermal management, and intelligent driving thermal management. In practice, the operation of the thermal management system is dominated by the vehicle control unit (VCU), which issues commands to control the actuators to heat or cool each thermally managed object, maintaining it within a suitable temperature range. These actuators continuously consume energy from the vehicle while heating or cooling the various thermally managed objects.

[0003] To enhance vehicle range and reduce thermal management energy consumption, related technologies employ corresponding thermal management energy-saving strategies from the perspective of the controller of a single thermal management object, based on the vehicle's operating conditions, such as cold start, driving, or stable operation, or based on whether the vehicle receives a battery heating request, a passenger heating request, or is in a plug-in charging scenario.

[0004] The energy-saving measures mentioned above, which are based on vehicle operating conditions or application scenarios and adopt corresponding strategies for individual thermal management objects, have significant limitations and low energy-saving efficiency. Summary of the Invention

[0017] Optionally, the vehicle thermal management method provided by the present invention, wherein energy-saving management is performed on at least one thermal management object of the vehicle, includes:

[0018] A stop signal is sent to the controller associated with the vehicle's thermal management object, causing the controller that receives the stop signal to respond to the stop signal and terminate the working state of the controlled actuator.

[0019] Optionally, the vehicle thermal management method provided by the present invention, wherein energy-saving management is performed on at least one thermal management object of the vehicle, includes:

[0020] The energy-saving management of the vehicle's thermal management object includes:

[0021] Receive a start request from a thermal management object. The start request message is used to request the actuator associated with the thermal management object to start in order to cool or heat the thermal management object.

[0022] In response to the startup request, determine the current temperature of the thermally managed object;

[0023] The startup request is ignored when the difference between the current temperature and the extreme operating temperature corresponding to the thermal management object does not exceed the second threshold.

[0024] Optionally, the vehicle thermal management method provided by the present invention further includes performing energy-saving management on the thermal management object of the vehicle:

[0025] When the difference between the current temperature and the extreme operating temperature corresponding to the thermal management object exceeds the second threshold, in response to the start request, a start command is sent to the actuator associated with the thermal management object, so that the actuator responds to the start command and performs the start operation.

[0026] Optionally, the vehicle thermal management method provided by the present invention, after ignoring the startup request, further includes:

[0027] Get the current temperature of the thermally managed object;

[0028] When the difference between the current temperature and the extreme operating temperature corresponding to the thermal management object exceeds the second threshold, or when the energy-saving factor does not meet the energy-saving management conditions, the system responds to the start request and sends a start signal to the controller of the thermal management object, so that the controller responds to the start signal and controls the associated actuator to perform the start operation.

[0029] Optionally, the energy-saving factor in the vehicle thermal management method provided by the present invention includes one or more of the following:

[0030] The vehicle's driving mode, driving coefficient, current temperature of the thermal management object, current temperature change rate, fault indicator, and disable command;

[0034] The vehicle thermal management method and vehicle provided by this invention can utilize vehicle-to-everything (V2X) technology to comprehensively consider thermal management needs from the perspective of the entire vehicle application. Specifically, it acquires vehicle navigation information and then determines driving parameters representing the remaining status of the vehicle's current driving task based on this information. When these driving parameters meet a threshold condition, it further determines whether the vehicle's energy-saving factor meets the conditions for implementing thermal energy-saving management. If the conditions are met, energy-saving management is implemented on the thermal management objects within the vehicle, causing the actuators associated with the thermal management objects to remain in a stopped state or remain in a stopped state. This allows for flexible control of all thermal management-related actuators during normal vehicle operation, effectively improving energy efficiency during vehicle operation.

[0035] In this invention, for a vehicle in motion, navigation information is used to determine driving parameters representing the remaining status of the current driving task. These parameters are then used as the basis for deciding whether to implement thermal management energy-saving measures. This allows for flexible implementation of energy-saving thermal management measures based on the remaining status of the driving task and the current actual situation of all thermal management objects within the vehicle. The entire energy-saving process is not limited to a single thermal management object and its corresponding controller, but applies to all thermal management objects in the vehicle, possessing universality and wide applicability to various thermal management systems within the vehicle. Furthermore, it is not confined to the vehicle controller itself, but achieves cross-domain integrated data processing. Additionally, the acquisition of navigation information through the vehicle network opens up a channel for vehicle-cloud collaboration, providing expansion space for big data cloud services.

[0046] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0047] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Although some embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the present invention. It should be understood that the accompanying drawings and embodiments of the present invention are for illustrative purposes only and are not intended to limit the scope of protection of the present invention.

[0048] It should be understood that the various steps described in the method embodiments of the present invention may be performed in different orders and / or in parallel. Furthermore, the method embodiments may include additional steps and / or omit the steps shown. The scope of the present invention is not limited in this respect.

[0049] The term "comprising" and its variations as used herein are open-ended, meaning "including but not limited to". The term "based on" means "at least partially based on". The term "one embodiment" means "at least one embodiment"; the term "another embodiment" means "at least one additional embodiment"; the term "some embodiments" means "at least some embodiments"; the term "optionally" means "optional embodiments". Definitions of other terms will be given in the following description. It should be noted that the concepts of "first", "second", etc., mentioned in this invention are used only to distinguish different devices, modules, or units, and are not intended to limit the order of functions performed by these devices, modules, or units or their interdependencies.

[0050] It should be noted that the terms "a" and "a plurality of" used in this invention are illustrative rather than restrictive. Those skilled in the art should understand that, unless otherwise expressly indicated in the context, they should be understood as "one or more".

[0051] The names of the messages or information exchanged between the multiple devices in the embodiments of the present invention are for illustrative purposes only and are not intended to limit the scope of these messages or information.

[0052] It can be understood that vehicle thermal management involves controlling the heating or cooling of various components that require heating or cooling. For example, the engine, passenger compartment, battery, motor, and intelligent driving system are considered thermal management objects. These are heated by a PTC actuator, or the refrigerant is compressed by a compressor actuator, which then works in conjunction with actuators such as water pumps, fans, and blowers to release or conduct heat.

[0053] Correspondingly, such as Figure 1 The schematic diagram of the vehicle system structure shown shows that, in actual control implementation, it is usually led by the vehicle control unit, i.e., the vehicle controller (VCU). Based on the target temperature and actual temperature of each thermal management object, it generates corresponding instructions, which cause the controller of the thermal management object to respond to the instructions and control the operation of the corresponding actuators, so that each thermal management object is maintained within a suitable temperature range.

[0054] During the process of thermal management of each thermal management object, i.e., the operation of the actuator to generate heating or cooling effects, the energy in the vehicle will be continuously consumed.

[0055] Therefore, to save vehicle energy consumption and extend vehicle range, energy-saving measures are implemented by managing the operation of heating or cooling actuators within the vehicle. For example, in related technologies, different thermal management strategies are adopted for each individual controller based on different vehicle operating conditions to optimize energy consumption. For instance, during cold starts, driving, and stable conditions, a stop command is transmitted to the corresponding controller to control the corresponding actuator to stop operation, i.e., to stop thermal management. Alternatively, for each individual controller, different thermal management strategies are adopted based on the vehicle's application scenario to optimize energy consumption. For example, determining whether a battery heating request, a passenger heating request, or whether the vehicle is in a plug-in charging state allows for energy-saving thermal management through the corresponding controller.

[0056] Clearly, the aforementioned thermal management energy-saving measures for individual controllers have significant limitations and low energy-saving efficiency for vehicles.

[0057] For example, a vehicle in motion may have different driving parameters depending on the completion level of its driving task. If the same thermal management strategy is uniformly configured for a single controller based on the operating conditions or application scenarios, the thermal management energy-saving measures will be rigid, resulting in low thermal management energy-saving efficiency and a poor passenger experience.

[0058] Therefore, in this invention, as Figure 2 As shown, in order to improve the flexibility and energy efficiency of thermal management, the completion status of driving tasks in the vehicle is combined, such as capturing navigation information and performing calculations to obtain driving parameters that reflect the remaining status of driving tasks. Then, the vehicle's driving parameters are used as a reliable basis for thermal management energy saving, and comprehensive energy-saving management is carried out on all thermal management objects in the vehicle. The thermal management energy-saving strategy is adjusted in real time to improve flexibility, ultimately improve energy efficiency and enhance the user experience.

[0059] The vehicle thermal management energy-saving method of the present invention can be derived from... Figure 2 The vehicle controller shown in the diagram executes the following: In the VCU, the acquired navigation information is processed and used as a reference for thermal management and energy-saving measures, thereby enabling corresponding thermal management and energy-saving control of the relevant actuators in the vehicle.

[0060] like Figure 2 As shown, the vehicle in this embodiment of the invention is equipped with a navigation system that can transmit data with the VCU, such as through a CAN network. Specifically, after the driver sets the destination via the navigation system's human-machine interface (HMI), the HMI subsystem can send navigation traffic information to the vehicle's CAN network during vehicle operation. The VCU can then read this navigation information from the CAN network for energy-saving thermal management.

[0061] It is understood that this invention, by utilizing navigation information and taking driving parameters reflecting the remaining status of the vehicle's current driving task as the basis for implementing specific thermal management energy-saving measures, is not limited to any single controlled object, i.e., not limited to a single thermal management object. Instead, it provides comprehensive management of all thermal management objects of the vehicle to achieve higher energy savings, thus enabling its widespread application in thermal management systems across various vehicle domains. Furthermore, by acquiring navigation information, it breaks through the limitations of the VCU controller, achieving cross-domain integration.

[0062] To better understand the vehicle thermal management energy-saving method provided by this invention, the following detailed explanation and description are provided with reference to the accompanying drawings.

[0063] like Figure 3 As shown, an embodiment of the present invention provides a vehicle thermal management energy-saving method, which specifically includes:

[0064] S110, obtain the vehicle's current navigation information.

[0065] S120, based on the navigation information, determine the driving parameters of the vehicle's current driving task, which represent the remaining status of the driving task.

[0066] Specifically, in combination Figure 2 As shown, for a specific driving task, the driver can set relevant data for the task, such as starting position, waypoints, and destination, in the navigation system's human-machine interface. After setting this, when the driving task is executed, the navigation system can generate corresponding navigation information in real time and send it to the vehicle's CAN network.

[0067] For example, after the settings are completed, during vehicle operation, the navigation system can generate information on the remaining road segments for this driving task, such as the length of each remaining road segment, the estimated travel time for each remaining road segment (i.e., the travel time of the remaining road segments), the congestion level of each remaining road segment, etc., and can transmit this information to the CAN network.

[0068] Furthermore, after the navigation system transmits the aforementioned navigation information to the vehicle's CAN network, the vehicle's VCU can obtain and parse this navigation information from the CAN network. It can then process the parsed results to obtain the vehicle's current driving parameters.

[0069] The driving parameter indicates the current completion status or remaining status of the vehicle's driving task. Specifically, the driving parameter may include the remaining driving time in the driving task, the completed driving time, or the required energy or the energy consumed, etc. This invention does not limit these parameters.

[0070] Furthermore, after calculating the vehicle's current driving parameters, these parameters can be compared with a first threshold to determine whether to execute subsequent thermal management energy-saving steps.

[0071] The first threshold can be a parameter value that is preset based on experience or testing, and serves as the minimum numerical representation of the remaining status or completion status of the corresponding driving task when energy-saving management is executed. That is, by comparing it with the calculated driving parameters, it is determined whether thermal management energy-saving measures can be considered under the current circumstances, i.e., S130 is executed.

[0072] It is understood that the navigation information acquisition step in this embodiment of the invention, namely the thermal management energy-saving method of the present invention, can be activated according to preset conditions. These preset conditions can be frequency or period. For example, a timer can be set to activate the method every ten minutes or half an hour when the vehicle performs a driving task to acquire navigation information. The activation method, i.e., the triggering condition, is determined according to the actual situation, and the present invention does not impose any restrictions on it.

[0073] S130, when the driving parameter does not exceed the first threshold, determine the current energy-saving factor of the vehicle. The energy-saving factor is used to determine whether the vehicle currently meets the energy-saving management conditions.

[0074] S140, when the energy-saving factor meets the energy-saving management conditions, energy-saving management is performed on the thermal management object of the vehicle, so that the heating or cooling actuator associated with the thermal management object stops working or remains in a stopped working state.

[0075] Specifically, when the driving parameters are compared with a first threshold and it is determined that the driving parameters do not exceed the first threshold, the specific information of the vehicle's current energy-saving factor can be determined to determine whether other factors besides the driving parameters meet the conditions for performing thermal management energy saving.

[0076] It can be understood that the energy-saving factor is one or more factors in a vehicle that affect whether thermal management energy-saving measures can be implemented; that is, the energy-saving factor is used to determine whether the vehicle currently meets the energy-saving management conditions.

[0077] Furthermore, when the determined energy-saving factor meets the conditions for energy-saving execution of thermal management, energy-saving management can be implemented for the thermal management object in the vehicle. That is, energy-saving control can be performed on the actuators corresponding to the thermal management objects in the vehicle that require heating or cooling, so that the heating or cooling actuators associated with the thermal management objects stop working or remain in a stopped state.

[0078] For example, when the determined energy-saving factor meets the thermal management energy-saving execution conditions, a stop signal can be transmitted to the corresponding controllers of components such as the passenger compartment, battery, motor, or intelligent driving system. The controllers respond to the stop signal and control the associated actuators, such as PTC, compressor, fan, or electric water pump, to perform energy-saving control, causing them to stop working, such as pausing or exiting the working state; or, the start request of the controller can be ignored, allowing the corresponding actuators to maintain their stopped working state, thereby achieving the purpose of energy saving.

[0079] It is understood that in this embodiment of the invention, responding to a stop signal and controlling the operating state of the actuator to pause or exit work can be achieved by the controller immediately responding to the stop signal so that the actuator can change its operating state; or, after the controller receives the stop signal, it can run for a period of time according to a set delay before controlling the change of the operating state.

[0080] It is understood that the thermal management energy-saving method provided in this embodiment of the invention can apply vehicle networking technology and comprehensively consider thermal management needs from the perspective of the whole vehicle application. That is, by capturing vehicle navigation information, driving parameters representing the remaining status of the vehicle's current driving task are calculated based on the captured navigation information. When the driving parameters meet the threshold conditions, it is further determined whether the vehicle's energy-saving factor meets the conditions for executing thermal management energy saving. When the conditions are met, energy-saving management is performed on the thermal management objects in the vehicle, so that the actuators corresponding to the thermal management objects remain in a stopped state or terminate their working state. This enables flexible control of all thermal management operating mechanisms under normal vehicle operation, effectively improving the energy-saving efficiency during vehicle operation.

[0081] In this embodiment of the invention, for a vehicle in motion, navigation information is used to obtain driving parameters representing the remaining status of the current driving task. These driving parameters are then used as the basis for executing thermal management energy-saving measures. The energy-saving strategy can be adjusted in a timely manner based on the remaining status of the driving task and the actual situation of each thermal management object in the vehicle. This allows the entire energy-saving process to be integrated across domains, rather than being limited to the vehicle controller. Furthermore, it is applicable to all thermal management objects in the vehicle, not just a single object, demonstrating universality and wide applicability to various aspects of vehicle thermal management systems. Additionally, obtaining navigation information through the vehicle network opens up a channel for vehicle-cloud collaboration, providing expanded space for big data cloud services.

[0082] Optionally, in some embodiments of the present invention, the navigation information may include traffic condition information, road length, and estimated travel time for the remaining road segments in the driving task. The traffic condition information may include congestion information and information on unexpected events. The present invention does not limit the specific content of the navigation information.

[0083] It is understandable that the estimated travel time for the remaining road segments is a prediction based on the length of each road segment and the corresponding congestion information.

[0084] In some embodiments of the present invention, in S120, in order to conveniently determine the remaining status of the driving task in a way that can intuitively reflect the driving task, the remaining driving time of the driving task can be used as a driving parameter to numerically represent the remaining status of the current driving task.

[0085] In S120, the determination of driving parameters based on the acquired navigation information can lead to the determination of the remaining driving time for the current driving task.

[0086] like Figure 4 As shown, this can be achieved through the following steps:

[0087] S01, based on the correction coefficients for each remaining road segment indicated by the navigation information, determine the corrected travel time for each remaining road segment.

[0088] S02, sum up the corrected travel times to obtain the remaining travel time.

[0089] Specifically, after obtaining the aforementioned navigation information, the vehicle controller can determine the corresponding correction coefficient based on the length of the remaining road segments, congestion information, and the driving temperature coefficient of the vehicle during the execution of the driving task. This correction coefficient may include the congestion coefficient, length coefficient, and / or driving temperature coefficient of each remaining road segment.

[0090] For example, for the length and congestion level of each road segment, corresponding levels can be predefined, and each level has a corresponding coefficient as a correction factor. During the execution of the driving task, a corresponding level, i.e., a mildness coefficient, is defined with the driving speed as a reference, and this mildness coefficient can also be used as a correction factor.

[0091] It is understandable that, in order to improve the accuracy of the calculation and provide an accurate basis for the implementation of thermal management energy-saving measures, the correction coefficients determined above for each road segment can be used to correct the estimated travel time of the corresponding road segment, so as to obtain the corrected travel time, so that the estimated travel time of each road segment can be closer to the reality.

[0092] Furthermore, after obtaining the above correction coefficients, when correcting the predicted travel time of each road segment, the correction coefficients can be multiplied by the travel time of each road segment, and the result of the product can be used as the corrected travel time of each road segment, i.e., the corrected travel time.

[0093] Finally, by summing the corrected travel times of each road segment (i.e., the products), we can obtain the travel parameters in S120, i.e., the remaining travel time.

[0094] It is understandable that after calculating the remaining driving time, the remaining time can be compared with the first threshold, and the comparison result can be used as the basis for whether to further implement thermal management energy-saving measures.

[0095] That is, the first threshold reflects the minimum requirement that the driving task is about to be completed. In this embodiment, the first threshold can also be a set duration, such as ten minutes or half an hour.

[0096] If the remaining driving time exceeds the first threshold, it means that thermal management energy-saving measures are not recommended at this time. That is, it is not advisable to implement energy-saving measures too early before reaching the destination, otherwise it may have too much impact on the driving experience. If the remaining time does not exceed the first threshold, it means that energy-saving management can be implemented without significantly affecting the driving experience.

[0097] It is understood that the above-mentioned driving parameters can also be the remaining / consumed energy of the driving task, the remaining distance, or the driving time, etc., as long as they can reflect the completion or remaining status of the task. This invention does not impose any restrictions on this.

[0098] It can also be understood that, in this embodiment of the invention, the remaining road lengths, congestion conditions, and driving temperature coefficients in the navigation information are used as corrections to the estimated travel time of each road segment. Finally, the corrected travel times of each road segment are summed to obtain a travel parameter that approximates the actual situation of the vehicle at present. In other words, the remaining travel time is used as a parameter to represent the remaining status of the travel task, so as to provide an accurate basis for subsequent thermal management energy-saving measures, thereby improving energy efficiency and user experience.

[0099] Optionally, in S130, in some embodiments of the present invention, in order to comprehensively consider thermal management requirements from the perspective of whole vehicle application, after calculating the driving parameters in S120 and comparing them, if the driving parameters do not exceed the first threshold, the current energy-saving factor of the vehicle can be further determined.

[0100] Specifically, this energy-saving factor can be the condition for each thermal management object to implement thermal management energy-saving measures, that is, it can be used as the basis for whether energy-saving measures can be implemented.

[0101] For example, the energy-saving factor may specifically include at least one or more of the following: vehicle driving mode, driving temperature coefficient, current temperature of the thermal management object, current temperature change rate of the thermal management object, thermal management fault indicator and disable command, etc.

[0102] Correspondingly, based on the above-mentioned energy-saving factors, the energy-saving factors meet the energy-saving management conditions, specifically referring to: the driving mode being in energy-saving (ECO) mode; the current temperature of the thermal management object being within a preset threshold range, that is, the difference between the current actual temperature and the extreme temperature of the thermal management object not exceeding the second threshold; the driving temperature and coefficient being lower than the third threshold; the temperature change rate of the thermal management object not exceeding the fourth threshold; the thermal management fault indicator indicating that there is currently no fault; and no disable command.

[0103] It is understandable that when implementing energy-saving management measures, in order to ensure that the temperature of each thermally managed object is within an acceptable range, a limit temperature range, i.e., the maximum and minimum operating temperature range, can be set according to the operating conditions of each thermally managed object. Correspondingly, when the difference between the current temperature and the limit temperature in the determined energy-saving factor does not exceed the second threshold, it means that the energy-saving factor meets the energy-saving management conditions.

[0104] Furthermore, when implementing energy-saving management measures, in order to meet the current driving style requirements and avoid adverse driving experiences, a lower limit, or third threshold, of the driving mildness coefficient can be determined based on the current driver's driving style. Correspondingly, the aforementioned driving mildness coefficient represents the current driver's driving style, such as mild or aggressive. A smaller driving mildness coefficient, i.e., not exceeding the third threshold, indicates milder driving and signifies that the energy-saving factor meets the energy-saving management conditions.

[0105] Furthermore, when implementing energy-saving management measures, to ensure that the temperature of each thermally managed object remains within an acceptable range and does not rapidly exceed this range, a fourth threshold can be set based on the individual operating conditions of each thermally managed object. This threshold represents the minimum acceptable rate of temperature change. Correspondingly, if the current rate of temperature change of the vehicle in the aforementioned energy-saving factor does not exceed this fourth threshold, then the energy-saving factor meets the energy-saving management conditions.

[0106] In addition, in order to further ensure that the various thermal management objects of the vehicle can operate normally during the implementation of energy-saving management measures, it is also necessary to determine the relevant fault indicators of the aforementioned thermal management objects to indicate that there are currently no faults, that is, to indicate that the fault factors meet the energy-saving management conditions.

[0107] Finally, in order for the vehicle controller to comprehensively manage each controller corresponding to each thermal management object, the disable indication information in the energy-saving factor indicates that there are no relevant prohibition instructions under the current driving conditions of the vehicle, which means that the energy-saving management conditions are met.

[0108] It is understood that in some embodiments, after determining the above-mentioned energy-saving factors, if all energy-saving factors indicate that the energy-saving management conditions are met, then the vehicle is currently capable of implementing energy-saving measures. Otherwise, the energy-saving management implementation conditions are not met.

[0109] It can also be understood that in some embodiments, certain energy-saving factors can be selectively ignored; that is, when some energy-saving factors meet the energy-saving management conditions, it means that the vehicle can currently implement energy-saving management measures. The specific combination of energy-saving factors can be determined according to the specific circumstances, and the present invention does not limit this.

[0110] Furthermore, such as Figure 6As shown, when all energy-saving factors meet the energy-saving management conditions and the remaining driving time is not greater than the first threshold, the VCU can set the b_bypass signal, that is, generate a stop signal, and implement energy-saving management measures.

[0111] In some embodiments of the present invention, when the energy-saving factors determined in S130 all meet the energy-saving management conditions and energy-saving management measures are implemented on the thermal management objects in the vehicle, a shutdown operation can be performed on the currently running actuators. Furthermore, in other embodiments, the stopped actuators can also be kept in a stopped state, thereby achieving effective energy-saving management from two aspects.

[0112] Specifically, in combination with, for example Figure 6 The logic diagram shown illustrates that when all determined energy-saving factors meet the energy-saving management conditions, energy-saving management measures can be implemented on the thermal management objects in the vehicle. Specifically, the VCU can perform pass-through control on the conventional thermal management logic.

[0113] For example, in some embodiments, when energy-saving management is performed, a stop signal can be generated to control the running actuator to stop working. That is, after energy-saving management is started, if there is an actuator associated with the thermal management object that is currently running, when the VCU generates a stop signal and sends it to the controller of the thermal management object, the controller responds to the stop signal and controls the associated actuator in the working state to stop running, so that it exits the working state, or exits the working state after a certain period of time, so as to achieve energy saving.

[0114] For example, when a thermally managed object is undergoing refrigeration management, that is, by using a compressor to compress refrigerant and in conjunction with a water pump and other actuators to drive the medium to release heat, when the VCU performs energy-saving management measures, it generates a stop signal and transmits it to the controller of the thermally managed object. The controller then responds to the stop signal by controlling the compressor and water pump to exit the working state, or to exit the working state after a preset time.

[0115] In addition, during the vehicle's routine thermal management process, when the VCU receives a heating or cooling request, such as battery heating, motor cooling, passenger compartment cooling, or engine cooling, the VCU will immediately execute the thermal management request, such as enabling PTC heating, activating compressor rotation, activating fan operation, or controlling the electronic water pump to work.

[0116] In other embodiments of the present invention, when energy-saving management is initiated, the actuator associated with the thermal management object is in a stopped state. If a request message from a thermal management object is received, the VCU performs b_ypass control on the thermal management logic. That is, when it is determined that the current temperature of the thermal management object meets the conditions, such as the difference between the current temperature and the operating temperature, i.e. the limit operating temperature, does not exceed the second threshold, the received request message can be ignored so that the corresponding actuator maintains its current stopped state.

[0117] Specifically, such as Figure 5 As shown, it may include the following steps:

[0118] S04, Receive the startup request for the thermal management object.

[0119] S05, in response to the startup request, determine the current temperature of the thermally managed object.

[0120] S06, when the difference between the current temperature and the extreme operating temperature corresponding to the thermal management object does not exceed the second threshold, the startup request is ignored.

[0121] Specifically, upon receiving a start request from a thermal management object, such as a heating or cooling request from the thermal management object, the current temperature of the thermal management object can be compared with its maximum or minimum allowable threshold temperature for normal operation. If the difference between the actual temperature and the threshold temperature does not exceed a certain range, i.e., does not exceed the second threshold, the thermal management request is not executed, i.e., the start request is ignored, so that its corresponding actuator remains in a stopped state.

[0122] Furthermore, in some embodiments of the present invention, after ignoring the thermal management request message, in order to ensure that each thermal management object can be maintained within the normal operating temperature range to ensure the normal operation of the vehicle, the temperature of the thermal management object can be monitored in real time, so as to stop thermal management energy saving in a timely manner and start the corresponding actuator to perform thermal management.

[0123] like Figure 5 As shown, the method may further include:

[0124] Obtain the current temperature of the thermally managed object;

[0125] S07, obtain the current temperature of the thermal management object.

[0126] S08, when the difference between the current temperature and the extreme operating temperature corresponding to the thermal management object exceeds the second threshold, respond to the start request and send a start signal to the controller of the thermal management object, so that the controller responds to the start signal and controls the associated actuator to perform the start operation.

[0127] Specifically, the current temperature of the thermally managed object can be periodically acquired. When the difference between the current temperature and the corresponding extreme operating temperature exceeds a second threshold, it indicates that the current situation does not meet the requirements for implementing energy-saving management measures. In this case, the bypass logic can be immediately stopped, i.e., in response to the aforementioned start request, a start signal is transmitted to the controller of the thermally managed object, causing the controller to respond to the start signal and activate the corresponding actuator to perform cooling or refrigeration operations.

[0128] For example, regarding the activation request for cooling demand of the thermal management object in the above embodiments, if it is initially ignored because energy-saving conditions are met, and the temperature of the thermal management object continues to rise during vehicle operation, exceeding the second threshold, it indicates that the current situation does not meet the energy-saving conditions. At this time, the vehicle controller can immediately stop energy-saving measures and, corresponding to the activation request, send a start command to the corresponding controller to control the corresponding compressor and electric water pump, etc., to start and perform cooling operations.

[0129] It is also understandable that during the implementation of energy-saving measures, other energy-saving factors can be monitored in real time. When a certain energy-saving factor fails to meet the energy-saving management conditions, the energy-saving measures can be stopped immediately, the start-up request can be responded to in a timely manner, and the corresponding thermal management operation can be implemented.

[0130] It is understood that in this invention, the above-mentioned operation of stopping the operation of the actuator performing thermal management and the operation of maintaining the stop operation of the actuator that is not currently in operation can be selectively performed according to the actual situation.

[0131] For example, based on the temperature and actual status of the specific thermal management object, the actuators of some thermal management objects can be kept in their current operating state, while only those not currently in operation can be kept in a state of shutdown; or a normal start-up operation can be performed on those not currently in operation, while a stop operation can be performed on the actuators that are currently in operation.

[0132] Alternatively, depending on the actual situation, both actions can be performed simultaneously: shutting down the units currently implementing thermal management, while maintaining the stopped state for units not currently in operation, thus achieving effective energy-saving management from two perspectives.

[0133] It is understood that the above two energy-saving operations can be selectively implemented according to the actual situation, and no specific restrictions are imposed.

[0134] It's also understandable that the above logic continues to execute until the driving ends or navigation exits. During the execution of the bypass logic, PTC, compressor, fan, electric water pump, etc., will temporarily stop working or terminate their work early without affecting vehicle safety and performance, thus achieving the effect of reducing energy consumption.

[0135] Furthermore, to better understand the thermal management energy-saving method provided by this invention, such as... Figure 8 A schematic diagram of the entire process is shown. For example... Figure 8 As shown, it includes:

[0136] S11, obtain the vehicle's current navigation information.

[0137] S12, Based on the navigation information, determine the driving parameters of the vehicle's current driving task, which represent the remaining status of the driving task.

[0138] S13, Receive the startup request for the thermal management object.

[0139] S14, determine whether the driving parameters exceed the first threshold.

[0140] S15 determines the vehicle's current energy efficiency factor.

[0141] S16, determine whether the energy-saving factor meets the energy-saving management conditions.

[0142] S17, a stop signal is sent to the controller associated with the vehicle's thermal management object, so that the controller that receives the stop signal responds to the stop signal and ends the working state of the controlled actuator.

[0143] S18, determine whether the difference between the current temperature and the extreme operating temperature of the thermally managed object exceeds the second threshold.

[0144] S19, Ignore the startup request.

[0145] S20, a start signal is sent to the controller of the thermally managed object, causing the controller to respond to the start signal and control the associated actuator to perform the start operation.

[0146] It is understandable that the specific execution order of S13 is not restricted and can be performed at any time in S18.

[0147] In addition, to ensure that all thermally managed objects can be maintained within the normal temperature range to ensure normal vehicle operation, as in the above embodiment, when it is determined in S120 and S14 that the driving parameters do not meet the energy-saving management implementation conditions, i.e., exceed the first threshold, or in S130 and S16 it is determined that a certain energy-saving factor does not meet the energy-saving conditions; or, as Figure 5As shown, in S06 and S18, when the difference between the determined current temperature and the extreme operating temperature corresponding to the thermally managed object exceeds the second threshold, but is not less than the second threshold, then upon receiving the start request, it is necessary to immediately respond to the start request and perform thermal management operations. Figure 6 As shown, when the vehicle controller is set to "0", it executes the normal thermal management logic, that is, it responds to and executes the thermal management start request normally. Specifically, when energy-saving management measures are not being implemented, it can immediately respond to the start request; when energy-saving management measures are being implemented, it immediately stops the energy-saving management measures and responds to the start request. Specifically, when driving parameters exceed a first threshold, or at least one energy-saving factor does not meet the energy-saving management conditions, or the difference between the current temperature of the thermally managed object and its corresponding extreme operating temperature exceeds a second threshold, it responds to the start request and sends a start signal to the controller of the thermally managed object, causing the controller to respond to the start signal and control the associated actuator to perform the start operation.

[0148] In this embodiment of the invention, the above-mentioned determination of driving parameters indicates that the driving parameters exceed a first threshold. At this time, if the vehicle controller receives a start request for a thermal management object, it can respond to the start request according to conventional logic, that is, send a start signal to the controller associated with the thermal management object, so that the controller responds to the start signal and controls the associated actuator to perform the start operation.

[0149] Alternatively, it can be determined when the driving parameters do not exceed a first threshold, and at least one energy-saving factor does not meet the energy-saving management conditions. In this case, similarly, if the vehicle controller receives a start request for a thermal management object, it can respond to the start request according to conventional logic, that is, send a start signal to the controller associated with the thermal management object, so that the controller responds to the start signal and controls the associated actuator to perform the start operation.

[0150] Alternatively, if the driving parameters do not exceed the first threshold and all energy-saving factors meet the energy-saving management conditions, but the current temperature of the thermal management object does not meet the energy-saving management conditions (i.e., the difference from the extreme operating temperature exceeds the fourth threshold), then similarly, if the vehicle controller receives a start request from a thermal management object, it can respond to the start request according to conventional logic, that is, send a start signal to the controller associated with the thermal management object, causing the controller to respond to the start signal and control the associated actuator to perform the start operation.

[0151] It is understood that the steps mentioned in the other embodiments above have been described in detail in the corresponding embodiments, and will not be repeated here.

[0152] In this embodiment of the invention, for a vehicle in motion, navigation information is used to obtain driving parameters representing the remaining status of the current driving task. These driving parameters serve as a preliminary basis for deciding whether to implement thermal management energy-saving measures. The current status of all thermal management objects, i.e., energy-saving factors, serves as a further basis for implementing energy-saving management measures. Based on the remaining status of the driving task and the current actual situation of all thermal management objects in the vehicle, start or stop signals are sent to the controllers of one or more thermal management objects to manage all controllers as a whole. This ensures that the actuators associated with the thermal management objects can be started or stopped in a timely manner during the implementation of energy-saving measures. Therefore, the entire energy-saving process is not limited to a single thermal management object and its corresponding controller, but applies to all thermal management objects in the vehicle, possessing universality and wide applicability to thermal management systems in various vehicle domains. Furthermore, it is not limited to the vehicle controller itself, but achieves cross-domain integrated data processing. In addition, obtaining navigation information through the vehicle network opens up a channel for vehicle-cloud collaboration, providing expansion space for big data cloud services.
