Technical Field

[0001] This invention relates to the field of vehicle thermal management technology, specifically to a thermal management system, method, electronic device, and vehicle for an intelligent driver assistance module. Background Technology

[0002] With the development of new energy vehicle technology, users' demand for the range of new energy vehicles has increased significantly. They require that the range of vehicles be reduced as much as possible in environments such as low temperature and high temperature. This requires improving the heat utilization efficiency of the vehicle's thermal management system, especially the temperature control of the vehicle's battery and passenger compartment at low temperatures. Therefore, heat pump control technology (i.e., the technology of using compressors to generate heat at low temperatures) and waste heat recovery technology (i.e., the technology of recovering and using heat generated by electric drive, engine components, etc.) have emerged. These technologies are now being applied to mass-produced models of major automakers.

Detailed Implementation

[0013] The embodiments of the present invention will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention and not for limiting the scope of protection of the present invention.

[0014] It should be noted that the embodiments of the present invention may involve the use of user data. In practical applications, user-specific personal data may be used in the scheme described herein within the scope permitted by applicable laws and regulations, provided that it complies with the applicable laws and regulations of the country (e.g., with the user's explicit consent, with the user being properly notified, etc.).

[0015] With the development of thermal management technology in new energy vehicles, the control of the actuators in the battery, electric drive, range extender, and intelligent driver assistance module of the vehicle is becoming increasingly complex. For vehicles with intelligent driver assistance modules, in order to meet the ever-increasing computing power requirements, the chips, power, and size of the intelligent driver assistance modules have all increased significantly. To ensure the normal operation of the intelligent driver assistance modules and enable them to operate in a normal temperature environment, many intelligent driver assistance modules currently use water-cooled systems. By ensuring the inlet temperature and coolant flow rate of the intelligent driver assistance modules, their heat dissipation requirements can be adequately met.

[0016] Furthermore, users have significantly increased their demands for the range of new energy vehicles, requiring minimal range reduction in environments such as low and high temperatures. This necessitates improving the heat utilization efficiency of the vehicle's thermal management system, especially in controlling the temperature of the battery and passenger compartment at low temperatures. This has led to the development of technologies such as heat pump control (using compressors to generate heat at low temperatures) and waste heat recovery (recovering and utilizing heat generated by electric drive and engine components). These technologies are already being used in mass-produced models from major automakers. However, with the introduction of intelligent driver assistance modules, the heat generated by these modules is typically released directly into the environment through a water circuit to the front radiator, resulting in heat waste.

[0017] Therefore, embodiments of the present invention provide a thermal management system for an intelligent driver assistance module, which manages the heat generated by the intelligent driver assistance module and can recover and utilize the heat generated, thereby improving the energy utilization efficiency of the entire thermal management system. Furthermore, embodiments of the present invention can also predict the subsequent operations of the intelligent driver assistance module (such as charging, sentry mode, navigation information, intelligent driving assistance needs, etc.) in advance to plan the heat utilization pattern of the intelligent driver assistance module, thereby enabling precise heat control of the intelligent driver assistance module. For example, if it is predicted that the battery will need to be heated in the future, the intelligent driver assistance module can be controlled to heat up to generate heat; if it is predicted that the battery will not need to be heated in the future, the intelligent driver assistance module can continue to operate, avoiding unnecessary energy consumption in the vehicle.

[0018] Reference Figure 1 The diagram illustrates a structural block diagram of a thermal management system for an intelligent assisted driving module provided in an embodiment of the present invention, comprising: A first coolant circuit, the first coolant circuit including an intelligent driver assistance module 1; The second coolant circuit includes battery 3; A first connecting component is disposed between the first coolant circuit and the second coolant circuit for connecting and separating the first coolant circuit and the second coolant circuit; wherein, when the first coolant circuit and the second coolant circuit are connected through the first connecting component, the coolant in the first coolant circuit carrying the heat generated by the intelligent assisted driving module 1 is introduced into the second coolant circuit to heat the battery 3.

[0019] In this embodiment of the invention, the vehicle may be equipped with a thermal management system for an intelligent assisted driving module. The thermal management system may include two circuits: a first coolant circuit and a second coolant circuit. Coolant flows through the pipes of the circuits and can be used to cool or heat the components in the circuits.

[0020] The first coolant circuit may include an intelligent driver assistance module 1. Specifically, the intelligent driver assistance module 1, often simply referred to as the intelligent driving module, is used to implement the vehicle's automatic driver assistance functions. It receives and processes data from sensors such as cameras, radar, and lidar on the vehicle to achieve environmental perception and path planning, thereby realizing the vehicle's automatic driver assistance functions. It is understandable that implementing the vehicle's automatic driver assistance functions requires massive computation; therefore, the intelligent driver assistance module 1 generates a significant amount of heat during operation.

[0021] The second coolant circuit may include battery 3, which stores electrical energy to power the vehicle. When the vehicle is in harsh environments, such as cold weather, the performance of battery 3 may be reduced. To counteract the effects of low temperatures on battery 3, it needs to be heated to maintain its optimal operating temperature range, such as 22-25°C, thus ensuring good vehicle performance even in cold weather.

[0022] The first connecting component 11 is disposed between the first coolant circuit and the second coolant circuit, and is used to connect and separate the first coolant circuit and the second coolant circuit; in some embodiments, the first connecting component 11 may be a two-position four-way valve.

[0023] In this embodiment of the invention, when the first coolant circuit and the second coolant circuit are connected through the first connecting component, the coolant in the first coolant circuit carrying the heat generated by the intelligent driver assistance module 1 is introduced into the second coolant circuit to heat the battery 3. In this way, the heat generated by the intelligent driver assistance module 1 of the vehicle can be recovered and provided to the battery, avoiding the waste of the heat generated by the intelligent driver assistance module 1.

[0024] In one embodiment of the present invention, the first coolant circuit may further include an electric drive module 3, which is connected to the intelligent assisted driving module 1. When the first coolant circuit and the second coolant circuit are connected through the first connecting component, the coolant in the first coolant circuit carrying the heat generated by the intelligent assisted driving module 1 and the electric drive module 2 is introduced into the second coolant circuit to heat the battery 3.

[0025] In this embodiment of the invention, the electric drive module 2 is used to convert the electrical energy stored in the battery into mechanical energy to drive the vehicle. Similarly, the electric drive module 2 also generates a large amount of heat during operation in order to achieve the electrical energy conversion. In some embodiments, the electric drive module 3 and the intelligent assisted driving module 1 can be connected in series or in parallel, depending on the actual situation of the vehicle. This embodiment of the invention does not impose any restrictions on this.

[0026] In this embodiment of the invention, when the first coolant circuit and the second coolant circuit are connected through the first connecting component, the coolant in the first coolant circuit carrying the heat generated by the intelligent driver assistance module 1 and the electric drive module 2 is introduced into the second coolant circuit to heat the battery 3. In this way, the heat generated by the intelligent driver assistance module 1 and the electric drive module 2 of the vehicle can be recovered and provided to the battery, avoiding the waste of the heat generated by the intelligent driver assistance module 1 and the electric drive module 2.

[0027] In one embodiment of the present invention, the first coolant circuit may further include: The first water pump 6 is connected to the first communication component 11 and is used to control the flow of coolant; The second connecting component 12 is connected to the first water pump 6 and is used to adjust the flow rate of the coolant; Radiator 4, which is connected to the second communicating component 12, is used to diffuse the heat of the coolant outward; The first water temperature sensor 8 is disposed between the radiator 4 and the coolant inlet of the intelligent driver assistance module 1 and the electric drive module 2, and is used to collect the temperature of the coolant flowing into the coolant inlet of the radiator 4 into the intelligent driver assistance module 1 and the electric drive module 2. The coolant outlets of the intelligent assisted driving module 1 and the electric drive module 2 are connected to the first communication component 11.

[0028] In some embodiments, the second communication component 12 may be a proportional three-way valve.

[0029] Reference Figure 2 This is a schematic diagram of a thermal management system for an intelligent assisted driving module provided in an embodiment of the present invention. Figure 2The circuit on the left is the first coolant circuit, which can also be called the electric drive or intelligent driving coolant circuit. The first water pump 6 can drive the coolant through the proportional three-way valve 12. The proportional three-way valve 12 has two outlets, one leading to the inlet of the radiator 4 and the other to the outlet of the radiator 4. Through the proportional control of the proportional three-way valve 12, the flow rate of the coolant through the radiator 4 can be actively adjusted, thereby controlling the speed at which heat diffuses from the radiator 4 to the outside. For example, the first water pump 6 can be adjusted to full speed so that the coolant in the first coolant circuit can flow at the maximum flow rate. The first water temperature sensor 8 collects the actual temperature of the coolant at the inlet of the electric drive module 2 and the intelligent driver assistance module 1. The coolant is supplied to the electric drive module 2 and the intelligent driver assistance module 1 respectively. The electric drive module 2 contains a temperature sensor that can measure the internal temperature of the electric drive module 2, and the intelligent driver assistance module 1 contains a temperature sensor that can measure the internal temperature of the intelligent driver assistance module 1. Afterwards, the coolant pipes merge and return to the inlet of the first water pump 1 through the two-position four-way valve 12.

[0030] In one embodiment of the present invention, the second coolant circuit may further include: Heater 10, connected to the first communication component 11, is used to heat the coolant; The second water temperature sensor 9 is disposed between the heater 10 and the coolant inlet of the battery 3, and is used to collect the temperature of the coolant flowing into the coolant inlet of the battery 3 from the heater 10. Heat exchanger 5 is connected to the coolant outlet of the battery 3 and the refrigerant circuit to exchange heat between the coolant and the refrigerant circuit 13. The second water pump 7 is connected to the heat exchanger 5 and the first communication assembly 11 and is used to control the flow of coolant.

[0031] Reference Figure 2 This is a schematic diagram of a thermal management system for an intelligent assisted driving module provided in an embodiment of the present invention. Figure 2 The circuit on the right is the second coolant circuit; the first coolant circuit can also be called the battery coolant circuit. The second water pump 7 drives the coolant through the two-position four-way valve 11, which is connected to the heater 10, which heats the coolant. The second water temperature sensor 9 collects the actual coolant temperature at the battery 3 inlet and is then connected to the battery 3's coolant inlet. The battery 3's coolant outlet is connected to the heat exchanger 10, which exchanges heat between the coolant and the refrigerant circuit 13.

[0032] The refrigerant circuit 13 can exchange heat between the passenger compartment and the coolant circuit through the heat exchange effect of the refrigerant. In some embodiments, the refrigerant circuit 13 may include a compressor, refrigerant piping, expansion valve, multi-way valve, condenser, evaporator, heat exchange plate, etc. In non-heat pump systems, the refrigerant circuit 13 cools the second coolant circuit through the heat exchange plate, that is, it exchanges heat with the coolant to lower the coolant temperature, thereby achieving the effect of cooling the battery in the second coolant circuit. In heat pump systems, the refrigerant circuit 13 can change its circuit mode, and through heat exchange with the coolant, it can both heat the coolant when the coolant temperature is low and cool it when the coolant temperature is high.

[0033] In specific implementation, refer to Figure 2 The two-position four-way valve 11 has two positions, such as... Figure 2 The position shown separates the first coolant circuit and the second coolant circuit, which contain the electric drive module 2 and the intelligent assisted driving module 1, and defines this state as circuit state 1. If the two-position four-way valve 11 rotates to the position shown... Figure 2 The position indicated by the dotted line represents the connection of the first coolant circuit and the second coolant circuit in series. This state is defined as circuit state 2. When the thermal management system is in circuit state 2, the heat generated by the intelligent driver assistance module 1 and the electric drive module 2 in the first coolant circuit can be recovered and supplied to the battery 3 in the second coolant circuit. This achieves the rational utilization of heat in the vehicle and avoids the waste of heat generated by the intelligent driver assistance module 1 and the electric drive module 2.

[0034] It should be added that the heat generated by the intelligent assisted driving module 1 and the electric drive module 2 in this embodiment of the invention can also be used to heat other components on the vehicle besides the battery, such as windows and door handles. If it is necessary to heat these components, the circuit can be set up with reference to the circuit of the battery. This embodiment of the invention does not impose any restrictions on this.

[0035] Reference Figure 3 The diagram illustrates a flowchart of a thermal management method for an intelligent assisted driving module provided in an embodiment of the present invention. Applicable to the thermal management system of the aforementioned intelligent assisted driving module, the method specifically includes the following steps: Step 301: Obtain vehicle data; Step 302: Obtain the system temperature data and outside temperature data of the vehicle's thermal management system; Step 303: Determine the heating mode based on the vehicle data, the system temperature data, and the outside temperature data; Step 304: Control the thermal management system according to the heating mode to introduce the coolant carrying the heat generated by the intelligent assisted driving module in the first coolant circuit into the second coolant circuit to heat the battery.

[0036] In one embodiment of the present invention, the vehicle data may at least include vehicle driving data and the operating status of the intelligent driver assistance module; the vehicle driving data may at least include driving duration, for example, the driving duration may be 300 seconds; the operating status of the intelligent driver assistance module may at least include the activation duration of the intelligent driver assistance module, for example, the activation duration of the intelligent driver assistance module may be 200 seconds. The system temperature data may at least include the first coolant temperature corresponding to the coolant at the coolant inlet of the intelligent driver assistance module, the second coolant temperature corresponding to the coolant at the coolant inlet of the battery, the temperature of the intelligent driver assistance module, and the battery temperature, etc.

[0037] In practical implementation, the thermal management system of the vehicle's intelligent driver assistance module can have multiple heating modes. Specifically, the heating modes can include passive waste heat recovery mode and active waste heat recovery mode. Specifically, in passive waste heat recovery mode, when the user is driving the vehicle normally and the intelligent driver assistance module is working normally, if the battery temperature is low, it will affect the battery's discharge power. If the temperature of the intelligent driver assistance module is higher than a certain threshold, the position can be adjusted through a two-position four-way valve to introduce the coolant heated by the intelligent driver assistance module in the first coolant circuit into the second coolant circuit, passively heating the battery in the second coolant circuit. The active waste heat recovery mode refers to the following: When the user is driving the vehicle normally (the vehicle is in motion) and the intelligent driver assistance module is working normally (the intelligent driver assistance module is activated), if the battery temperature is low, affecting the battery's discharge power, the proportional three-way valve in the first coolant circuit is actively adjusted to position 1, thereby stopping the heat generated by the intelligent driver assistance module from being dissipated through the radiator. At the same time, the intelligent driver assistance module is actively put into self-heating mode, that is, the intelligent driver assistance module actively heats itself, so that the intelligent driver assistance module can provide heat in addition to the heat generated during normal operation. If the first water temperature sensor rises above a certain temperature, or the temperature of the intelligent driver assistance module is higher than a certain threshold, the position of the two-position four-way valve can be adjusted to introduce the coolant heated by the intelligent driver assistance module in the first coolant circuit into the second coolant circuit, actively heating the battery in the second coolant circuit.

[0038] In this embodiment of the invention, vehicle data and system temperature data of the thermal management system of the intelligent driver assistance module can be obtained, as well as outside temperature data. Then, a heating mode can be determined based on the vehicle data, system temperature data, and outside temperature data. Subsequently, the thermal management system can be controlled according to the heating mode to introduce the coolant carrying the heat generated by the intelligent driver assistance module in the first coolant circuit into the second coolant circuit to heat the battery, thereby realizing the recovery and utilization of the heat generated by the intelligent driver assistance module and avoiding heat waste.

[0039] In one embodiment of the present invention, the method may further include: The thermal management system is controlled according to the heating mode to introduce the coolant carrying the heat generated by the intelligent assisted driving module and the electric drive module in the first coolant circuit into the second coolant circuit to heat the battery.

[0040] In one embodiment of the present invention, the system temperature data may include at least the first coolant temperature corresponding to the coolant at the coolant inlet of the intelligent driver assistance module and the electric drive module, the second coolant temperature corresponding to the coolant at the coolant inlet of the battery, the temperature of the intelligent driver assistance module, the temperature of the electric drive module, and the battery temperature, etc.

[0041] In practice, when the user drives the vehicle normally and the intelligent driver assistance module works normally, if the battery temperature is low, it will affect the battery's discharge power. If the temperature of the intelligent driver assistance module and the electric drive module are higher than a certain threshold, the position can be adjusted by a two-position four-way valve to introduce the coolant heated by the intelligent driver assistance module and the electric drive module in the first coolant circuit into the second coolant circuit, thus passively heating the battery in the second coolant circuit. Furthermore, when the user is driving the vehicle normally (the vehicle is in motion) and the intelligent driver assistance module is working normally (the intelligent driver assistance module is activated), if the battery temperature is low, affecting the battery's discharge power, the proportional three-way valve in the first coolant circuit will be actively adjusted to position 1, thereby stopping the heat generated by the intelligent driver assistance module and the electric drive module from being dissipated through the radiator. At the same time, the intelligent driver assistance module will actively enter the self-heating mode, that is, the intelligent driver assistance module will actively heat itself, so that the intelligent driver assistance module can provide heat in addition to the heat generated during normal operation. If the first water temperature sensor rises above a certain temperature, or if the temperature of the intelligent driver assistance module and the electric drive module is higher than a certain threshold, the position of the two-position four-way valve can be adjusted to introduce the coolant heated by the intelligent driver assistance module and the electric drive module in the first coolant circuit into the second coolant circuit, actively heating the battery in the second coolant circuit.

[0042] In this embodiment of the invention, vehicle data and system temperature data of the thermal management system of the intelligent driver assistance module can be obtained, as well as outside temperature data. Then, a heating mode can be determined based on the vehicle data, system temperature data, and outside temperature data. Subsequently, the thermal management system can be controlled according to the heating mode to introduce the coolant carrying the heat generated by the intelligent driver assistance module and the electric drive module in the first coolant circuit into the second coolant circuit to heat the battery. This realizes the recovery and utilization of the heat generated by the intelligent driver assistance module and the electric drive module, avoiding heat waste.

[0043] In one embodiment of the present invention, step 103, determining the heating mode based on the vehicle data, the system temperature data, and the outside temperature data, may include: When the outside temperature data is less than the first preset outside temperature threshold, the driving time of the vehicle exceeds the preset driving time, and the activation time of the intelligent assisted driving module is greater than the preset activation time, if the first coolant temperature is greater than the first preset temperature threshold, the electric drive module temperature is greater than the second preset temperature threshold, the intelligent assisted driving module temperature is greater than the third preset temperature threshold and the duration exceeds the first preset time threshold, the second coolant temperature is less than the fourth preset temperature threshold, and the battery temperature is less than the fifth preset temperature threshold and the duration exceeds the second preset time threshold, then the heating mode is determined to be the passive waste heat recovery mode. When the outside temperature data is less than the second preset outside temperature threshold, the vehicle is determined to be in a driving state based on the driving state data, and the intelligent assisted driving module is in the activated state, if the first coolant temperature is less than the sixth preset temperature threshold, the electric drive module temperature is less than the seventh preset temperature threshold, the intelligent assisted driving module temperature is less than the eighth preset temperature threshold, and the duration exceeds the third preset time threshold, then the heating mode is determined to be the active waste heat recovery mode. During the process from vehicle power-on to vehicle power-off, only one of the passive waste heat recovery mode and the active waste heat recovery mode is in operation.

[0044] In this embodiment of the invention, when the vehicle is in motion and the intelligent assisted driving module is activated, it begins to monitor relevant data of the vehicle and its thermal management system. Specifically, when the outside temperature is less than a first preset outside temperature threshold (e.g., 10 degrees Celsius), the driving time exceeds a preset driving time (e.g., 300 seconds), and the activation time of the intelligent assisted driving module exceeds a preset activation time (e.g., 20 seconds), if the first coolant temperature collected by the first water temperature sensor is greater than a first preset temperature threshold (e.g., 40°C), the electric drive temperature is greater than a second preset temperature threshold (e.g., 50°C), and the intelligent driving module temperature is greater than a third preset temperature threshold (e.g., 70°C), and the duration is determined by timer 1 to exceed a first preset time threshold (e.g., the duration exceeds 20 seconds), and the second coolant temperature collected by the second water temperature sensor is less than a fourth preset temperature threshold (e.g., 10°C), and the battery temperature is less than a fifth preset temperature threshold (e.g., 10°C), and the duration is determined by timer 2 to exceed a second preset time threshold (e.g., the duration exceeds 20 seconds), then the vehicle is enabled to enter the passive waste heat recovery mode of the intelligent driving module.

[0045] When the vehicle is in motion and the intelligent assisted driving module is activated, it begins to monitor relevant data of the vehicle and its thermal management system. Specifically, if the outside temperature is less than the second preset outside temperature threshold (e.g., 0 degrees Celsius), and if the first coolant temperature collected by the first water temperature sensor is less than the sixth preset temperature threshold (e.g., 20°C), the electric drive temperature is less than the seventh preset temperature threshold (e.g., 25°C), and the intelligent driving module temperature is less than the eighth preset temperature threshold (e.g., 25°C), and the duration is determined by timer 3 to exceed the third preset time threshold (e.g., the duration exceeds 20 seconds), then the vehicle is enabled to enter the active waste heat recovery mode of the intelligent driving module.

[0046] It should be noted that within a single driving cycle, such as the period from vehicle power-on to power-off, only one of the passive and active waste heat recovery modes will be operational at a time. Specifically, passive and active waste heat recovery modes cannot coexist within a single driving cycle; that is, if passive waste heat recovery mode is activated, active waste heat recovery mode cannot be activated. Similarly, if active waste heat recovery mode has been activated, passive waste heat recovery mode cannot be activated. If one heating mode is activated within the same driving cycle, the other heating mode cannot be activated during that cycle.

[0047] In one embodiment of the present invention, step 104, controlling the thermal management system according to the heating mode to introduce the coolant carrying the heat generated by the intelligent assisted driving module and the electric drive module in the first coolant circuit into the second coolant circuit to heat the battery, may include: When the heating mode is passive waste heat recovery mode, the second communication component is controlled to prevent the coolant from passing through the radiator; By controlling the first connecting component to connect the first coolant circuit and the second coolant circuit, the coolant carrying the heat generated by the intelligent assisted driving module and the electric drive module in the first coolant circuit is introduced into the second coolant circuit to heat the battery.

[0048] In this embodiment of the invention, when the heating mode is determined to be a passive waste heat recovery mode, refer to Figure 2 It can control the proportional three-way valve 12 to switch to position 1, and at the same time control the first water pump to run at full speed, so that the coolant no longer passes through the external radiator, reducing heat dissipation to the external environment and keeping the temperature of the coolant in the first coolant circuit at a high level.

[0049] Furthermore, the two-position four-way valve 11 is switched to position 2, so that the first coolant circuit and the second coolant circuit are connected in series. At the same time, the first water pump and the second water pump are controlled to run at full speed. The coolant carrying heat in the first coolant circuit can flow into the second coolant circuit and mix with it, thereby heating the battery in the second coolant circuit.

[0050] In one embodiment of the present invention, the method may further include: When the operating time of the passive waste heat recovery mode exceeds a first preset operating threshold, the external temperature data exceeds a preset first external temperature rise threshold, the first coolant temperature exceeds a first preset temperature rise threshold, the electric drive module temperature is less than a ninth preset temperature threshold, the intelligent assisted driving module temperature is less than a tenth preset temperature threshold, the second coolant temperature is greater than an eleventh preset temperature threshold, the battery temperature exceeds a second preset temperature rise threshold, or the battery temperature is greater than a twelfth preset temperature threshold, the second connecting component is controlled to allow coolant to pass through the radiator, and the first connecting component is controlled to separate the first coolant circuit and the second coolant circuit.

[0051] In this embodiment of the invention, when the passive waste heat recovery mode is enabled, monitoring begins on data such as the outside temperature, the first coolant temperature collected by the first water temperature sensor, the electric drive temperature, the intelligent driving module temperature, the second coolant temperature collected by the second water temperature sensor, and the battery temperature.

[0052] Furthermore, if the outside temperature data exceeds the preset first outside temperature rise threshold (e.g., exceeding 10°C) when the passive waste heat recovery mode is enabled, or the first coolant temperature collected by the first water temperature sensor exceeds the first preset temperature rise threshold (e.g., exceeding 15°C), or the electric drive temperature is less than the ninth preset temperature threshold (e.g., 40°C), or the intelligent driving module temperature is less than the tenth preset temperature threshold (e.g., 55°C), or the second coolant temperature collected by the second water temperature sensor is greater than the eleventh preset temperature threshold (e.g., 25°C), or the battery temperature is greater than the twelfth preset temperature threshold (e.g., 20°C), or the working time of the passive waste heat recovery mode exceeds the first preset working threshold (e.g., 900s), the passive waste heat recovery mode will be exited if the above conditions are met. At this time, the coolant can be passed through the radiator 4 by controlling the proportional three-way valve 12, and the first coolant circuit and the second coolant circuit can be separated by controlling the two-position four-way valve 11.

[0053] It should be noted that if the passive waste heat recovery mode has been enabled once in this driving cycle, this mode will not be activated again in this driving cycle.

[0054] For example, refer to Figure 4 The flowchart below shows a passive waste heat recovery mode of an intelligent assisted driving module provided in an embodiment of the present invention. The specific steps are as follows: Step 401: Is the vehicle in motion and is the intelligent driving module activated? If yes, proceed to step 402; otherwise, return to step 401. Step 402: Vehicle driving time > 300s, and intelligent driving module activation time > 200s; if yes, proceed to step 403; otherwise, return to step 402. Step 403: Outside temperature data <10℃; if yes, proceed to step 404; otherwise, return to step 403. Step 404: If the first coolant temperature is >40℃, the electric drive temperature is >40℃ and the intelligent driving module temperature is >70℃, timer 1 starts counting; if yes, proceed to step 405; otherwise, return to step 404. Step 405: If the second coolant temperature is <10℃ and the battery temperature is <10℃, timer 2 starts counting; if yes, proceed to step 406; otherwise, return to step 404. Step 406: Timer 1 > 20s and Timer 2 > 20s; if yes, proceed to step 407; otherwise, return to step 404. Step 407: Control the proportional three-way valve to switch to position 1, and control the first water pump to run at full speed; Step 408: Control the two-position four-way valve to switch to position 2, and control the second water pump to run at full speed; Step 409: Monitor the vehicle exterior temperature data, first coolant temperature, electric drive temperature, intelligent driving module temperature, second coolant temperature, and battery temperature; if the passive waste heat recovery mode operates for more than 900 seconds, the vehicle exterior temperature rises by more than 10°C, the first coolant temperature rises by more than 15°C, the electric drive temperature is less than 40°C, the intelligent driving module temperature is less than 55°C, the second coolant temperature is more than 25°C, and the battery temperature rises by more than 20°C, or the battery temperature is more than 20°C, then proceed to step 410; otherwise, return to step 409. Step 410: Return the proportional three-way valve to position 2 and the two-position four-way valve to position 1.

[0055] Specifically, when the ambient temperature outside the vehicle is low (e.g., the outside temperature is less than 10 degrees Celsius), the vehicle is in driving mode and the intelligent driving module is activated. If the temperature of the first coolant is greater than a certain threshold (e.g., 40°C), the electric drive temperature is greater than a certain threshold (e.g., 50°C), the temperature of the intelligent driving module is greater than a certain threshold (e.g., 70°C), the temperature of the second coolant is less than a certain threshold (e.g., 10°C), the battery temperature is less than a certain threshold (e.g., 10°C), the vehicle driving time is greater than a certain threshold (e.g., 300 seconds), and the vehicle intelligent driving module is activated for a period of time greater than a certain threshold (e.g., 200 seconds), and if the above conditions are met for more than 20 seconds, the passive waste heat recovery mode of the intelligent driving module will be enabled. Furthermore, the proportional three-way valve is switched to position 1, and the water pump 1 is controlled to run at full speed, so that the coolant no longer passes through the external radiator, reducing heat dissipation to the external environment and keeping the temperature of the coolant in the first coolant circuit at a high level.

[0056] Furthermore, the two-position four-way valve is switched to position 2, so that the first coolant circuit and the second coolant circuit are connected in series. At the same time, the water pump 1 and water pump 2 are controlled to run at full speed. The coolant carrying the heat of the intelligent driving module and electric drive module in the first coolant circuit can flow into the second coolant circuit to mix with the water, thereby heating the battery in the second coolant circuit. Furthermore, it monitors the outside temperature, the first coolant temperature, the electric drive temperature, the intelligent driving module temperature, the second coolant temperature, the battery temperature, etc.

[0057] Furthermore, if the outside temperature rises by a certain threshold (e.g., more than 10°C) compared to when passive heating is enabled, or the first coolant temperature drops by a certain threshold (e.g., 15°C) compared to when passive waste heat recovery mode is enabled, or the electric drive temperature is less than a certain threshold (e.g., 40°C), or the intelligent driving module temperature is less than a certain threshold (e.g., 55°C), or the second coolant temperature rises by a certain threshold (e.g., 25°C) compared to when passive waste heat recovery mode is enabled, or the battery temperature rises by a certain threshold (e.g., 20°C), or the battery temperature exceeds a certain threshold (e.g., 20°C), or the operating time in passive waste heat recovery mode exceeds a certain threshold (e.g., 900s), then the passive waste heat recovery mode will be exited.

[0058] In one embodiment of the present invention, controlling the thermal management system according to the heating mode to introduce coolant carrying heat generated by the intelligent assisted driving module and the electric drive module in the first coolant circuit into the second coolant circuit to heat the battery includes: When the heating mode is active waste heat recovery mode, the second connecting component is controlled to prevent the coolant from passing through the radiator; Control the intelligent assisted driving module to perform active heating; When the temperature of the first coolant exceeds the third preset temperature rise threshold, the temperature of the electric drive module exceeds the fourth preset temperature rise threshold, or the temperature of the intelligent driver assistance module exceeds the fifth preset temperature rise threshold, the first connecting component is controlled to connect the first coolant circuit and the second coolant circuit, so as to introduce the coolant carrying the heat generated by the intelligent driver assistance module and the electric drive module in the first coolant circuit into the second coolant circuit to heat the battery.

[0059] In this embodiment of the invention, when the heating mode is determined to be an active waste heat recovery mode, reference is made to... Figure 2 It can actively switch the proportional three-way valve 11 to position 1 to control the first water pump to run at full speed, so that the coolant is not dissipated through the external radiator 4.

[0060] Furthermore, the intelligent driving module is actively requested to enter the self-heating mode, that is, the intelligent driving module actively heats up and starts monitoring data such as the outside temperature, the first coolant temperature collected by the first water temperature sensor, the electric drive temperature, and the intelligent driving module temperature. When the first coolant temperature collected by the first water temperature sensor rises above the third preset temperature rise threshold (e.g., 15℃), or the electric drive temperature rises above the fourth preset temperature rise threshold (30℃), or the intelligent driving module temperature rises above the fifth preset temperature rise threshold (e.g., 35℃), the two-position four-way valve is controlled to switch to position 2, and the second water pump is controlled to run at full speed to introduce hot water from the first coolant circuit into the second coolant circuit, actively heating the battery in the second coolant circuit.

[0061] In one embodiment of the present invention, the method may further include: If the monitoring detects that the active waste heat recovery mode has been operating for more than a second preset operating threshold, the vehicle exterior temperature exceeds a preset second vehicle exterior temperature rise threshold, the first coolant temperature exceeds a thirteenth preset temperature threshold, the electric drive module temperature exceeds a fourteenth preset temperature threshold, the intelligent assisted driving module temperature exceeds a fifteenth preset temperature threshold, or the second coolant temperature exceeds a sixteenth preset temperature threshold, and the battery temperature exceeds a seventeenth preset temperature threshold, the second connecting component is controlled to allow coolant to pass through the radiator, and the first connecting component is controlled to separate the first coolant circuit and the second coolant circuit.

[0062] In this embodiment of the invention, after enabling the active waste heat recovery mode, the system begins to monitor data such as the outside temperature, the first coolant temperature collected by the first water temperature sensor, the electric drive temperature, the intelligent driving module temperature, the second coolant temperature collected by the second water temperature sensor, and the battery temperature.

[0063] Furthermore, if the active waste heat recovery mode operates for more than the second preset operating threshold (900s), or if the outside temperature data exceeds the preset second outside temperature rise threshold (e.g., 10℃), the first coolant temperature collected by the first water temperature sensor is greater than the thirteenth preset temperature threshold (e.g., 50℃), or the electric drive temperature is greater than the fourteenth preset temperature threshold (e.g., 60℃), or the intelligent driving module temperature is greater than the fifteenth preset temperature threshold (e.g., 70℃), or the second coolant temperature collected by the second water temperature sensor is greater than the sixteenth preset temperature threshold (e.g., 25℃), or the battery temperature is greater than the seventeenth preset temperature threshold (e.g., 20℃), then the active waste heat recovery mode will exit. At this time, the proportional three-way valve will be controlled to reach position 2, and the two-position four-way valve will be controlled to return to position 1, and the intelligent driving module will no longer be requested to self-heat.

[0064] It should be noted that if the active waste heat recovery mode has been enabled once in this driving cycle, this mode will not be activated again in this driving cycle.

[0065] For example, refer to Figure 5 The flowchart below shows an active waste heat recovery mode for an intelligent assisted driving module provided in this embodiment of the invention. The specific steps are as follows: Step 501: Is the vehicle in motion and is the intelligent driving module activated? If yes, proceed to step 502; otherwise, return to step 501. Step 502: Outside temperature data < 0℃; if yes, proceed to step 503; otherwise, return to step 502. Step 503: The first coolant temperature is <20℃, the electric drive temperature is <25℃, and the intelligent driving module temperature is <25℃; timer 3 starts counting; if yes, proceed to step 504; otherwise, return to step 503. Step 504: Timer 3 > 20s; if yes, proceed to step 505; otherwise, return to step 503. Step 505: Actively switch the proportional three-way valve to position 1, and the first water pump will run at full speed; Step 506: Request the self-heating mode of the intelligent driving module; Step 507: The temperature of the first coolant rises by more than 15°C, or the temperature of the electric drive rises by more than 30°C, or the temperature of the intelligent driving module rises by more than 35°C; if yes, proceed to step 508; otherwise, return to step 506. Step 508: Control the two-position four-way valve to switch to position 2, and control the second water pump to run at full speed; Step 509: Monitor the temperature of the first coolant, electric drive, intelligent driving module, second coolant, and battery. If the active waste heat recovery mode operates for more than 900 seconds, the outside temperature rises by more than 10°C, the first coolant temperature exceeds 50°C, the electric drive temperature exceeds 60°C, the intelligent driving module temperature exceeds 70°C, the second coolant temperature exceeds 25°C, or the battery temperature exceeds 20°C, then proceed to step 510; otherwise, return to step 509. Step 510: Return the proportional three-way valve to position 2 and the two-position four-way valve to position 1.

[0066] Specifically, when the ambient temperature outside the vehicle is extremely low (e.g., the outside temperature is less than 0 degrees Celsius), the vehicle is in motion, the intelligent driving module is on, and if the first water temperature sensor is below a certain threshold (e.g., 20°C), the electric drive temperature is below a certain threshold (e.g., 25°C), and the intelligent driving module temperature is below a certain threshold (e.g., 25°C), if the above conditions are met, timer 1 will start timing. If the timing time exceeds a certain threshold, the proportional three-way valve will be actively switched to position 1 to control water pump 1 to run at full speed, so that the coolant is not cooled through the external radiator.

[0067] Further, the system actively requests the self-heating mode of the intelligent driving module, monitors the first water temperature sensor, the electric drive temperature, and the intelligent driving module temperature. When the temperature of the first water temperature sensor rises more than a certain threshold (e.g., 15°C) compared to the previous step when the proportional three-way valve was switched, or the electric drive temperature rises more than a certain threshold (30°C), or the intelligent driving module temperature rises more than a certain threshold (e.g., 35°C), the system controls the two-position four-way valve to switch to position 2, controls the second water pump to run at full speed, and the coolant carrying the heat from the intelligent driving module and the electric drive module in the first coolant circuit can flow into the second coolant circuit to mix the water, actively heating the battery in the second coolant circuit.

[0068] Furthermore, if the active waste heat recovery mode operates for more than a certain threshold (900s), the mode will be exited. If, during this process, the outside temperature rises above a certain threshold (e.g., 10°C), the first coolant temperature exceeds a certain threshold (e.g., 50°C), the electric drive temperature exceeds a certain threshold (e.g., 60°C), the intelligent driving module temperature exceeds a certain threshold (e.g., 70°C), the second coolant temperature reaches a certain threshold (e.g., 25°C), or the battery temperature reaches a certain threshold (e.g., 20°C), and the above conditions are met, the proportional three-way valve will be controlled to position 2, the two-position four-way valve will be controlled to return to position 1, the intelligent driving module self-heating mode will no longer be requested, and the active waste heat recovery mode will be exited.

[0069] In one embodiment of the present invention, controlling the intelligent assisted driving module to perform active heating may include: Obtain the remaining navigation mileage of the vehicle; Obtain the usage percentage of the intelligent assisted driving module; The predicted heat generation of the intelligent assisted driving module is determined based on the usage ratio. The predicted power consumption of the battery is determined based on the remaining navigation mileage and the battery data; the battery data includes the battery level and the current battery temperature. The first predicted battery temperature rise of the battery is determined based on the predicted power consumption. A second predicted battery temperature rise is determined based on the predicted heat generation; The target battery temperature is determined based on the current battery temperature, the first predicted battery temperature rise, and the second predicted battery temperature rise. The intelligent driver assistance module is actively heated according to the target battery temperature.

[0070] In one embodiment of the present invention, the step of controlling the intelligent assisted driving module to actively heat up according to the target battery temperature includes: When the target battery temperature is lower than the first preset start-up temperature threshold, the intelligent assisted driving module is controlled to actively heat up. When the target battery temperature is greater than or equal to the first preset start-up temperature threshold and less than or equal to the second preset start-up temperature threshold, the intelligent assisted driving module is prohibited from actively heating. When the target battery temperature is greater than the second preset start-up temperature threshold, the second connecting component is controlled to allow the coolant to pass through the radiator, and the first connecting component is controlled to separate the first coolant circuit and the second coolant circuit.

[0071] In this embodiment of the invention, the remaining heat of the intelligent driving module can be predicted in advance based on the subsequent usage (usage ratio) of the intelligent driving module. The estimated heat generation of the intelligent driving module can be calculated by looking up a table based on the remaining navigation mileage. The expected heat generation of the intelligent driving module can be dynamically adjusted according to the current working state of the battery.

[0072] Reference Figure 6 The following is a flowchart illustrating the heat utilization prediction process of an intelligent assisted driving module provided in this embodiment of the invention. The specific process of this function is as follows: Step 601: Obtain the remaining navigation mileage and the percentage of intelligent driving usage; Step 602: Obtain the predicted heat generation of the intelligent driving module by looking up the table; Step 603: Monitor battery power and current battery temperature T0, and calculate the predicted power consumption for the remaining navigation range. Step 604: Calculate the first predicted battery temperature rise T1 based on the predicted power consumption; Step 605: Obtain the second predicted battery temperature rise T2 based on the predicted heat generation of the intelligent driving module; Step 606: T0 + T1 + T2 = Battery target temperature T5; Step 607: T5 < 22℃; if yes, proceed to step 608; otherwise, proceed to step 609. Step 608: Activate the active waste heat recovery mode in advance (depending on conditions); Step 609: T5 > 25℃; if yes, proceed to step 610; otherwise, end. Step 610: Disable active waste heat recovery mode throughout the entire process; Specifically, the system continuously acquires the remaining mileage for the driver's subsequent navigation journey. Based on the proportion of intelligent driving usage, it looks up a table to predict the heat generation of the intelligent driving module. Further, it monitors the current battery level and current battery temperature T0, and calculates the predicted power consumption based on the subtotal energy consumption. Further, it calculates the first predicted battery temperature rise T1 based on the predicted power consumption. Further, it calculates the second predicted battery temperature rise T2 that the predicted heat generation can provide based on the predicted heat generation of the intelligent driving module. Further, based on T0, T1, and T2, it obtains the predicted target battery temperature T5. Based on the difference between T5 and the optimal battery operating temperature (typically 25℃), it preemptively activates and deactivates the active waste heat recovery mode. If T5 is less than 22℃ (the first preset start-up temperature threshold), the active waste heat recovery mode is activated in advance, i.e., the intelligent driving module is controlled to enter self-heating mode for active heating. If T5 is greater than 25℃ (the second preset start-up temperature threshold), the active waste heat recovery mode is disabled throughout. If T5 is greater than 22℃ but less than 25℃, the intelligent driving module does not need active heating; it can generate heat normally without this.

[0073] In summary, this invention provides a thermal management system for an intelligent driver assistance module, which manages the heat generated by the module and can recover and reuse it, thereby improving the energy efficiency of the entire thermal management system. Furthermore, this invention can also predict the future operation of the intelligent driver assistance module (such as charging, sentry mode, navigation information, and intelligent driving assistance needs) and plan the heat utilization pattern in advance, thus enabling precise heat control of the module. For example, if it is predicted that the battery will need heating in the future, the intelligent driver assistance module can be controlled to heat up; if it is predicted that the battery will not need heating, the module can continue to operate, avoiding unnecessary energy consumption in the vehicle.
