[0002] The present application relates to the field of intelligent vehicles, in particular to a heating control method and device. BACKGROUND

[0003] Heat convection is also known as convective heat transfer. Heat convection mechanism is a way of heat transfer. Heat convection mechanism refers to the vertical movement phenomenon of air or fluid caused by temperature difference. The air conditioner of a vehicle uses heat convection mechanism for heating.

[0004] Currently, the air conditioner of a vehicle is used to heat the passenger cabin to provide a comfortable environment for the passenger cabin. In the case that the ambient temperature outside the vehicle and the cabin temperature inside the vehicle are very low, the vehicle has a rapid heating demand, but due to the relatively dispersed heating range of the air conditioner, it takes a long time for the passengers in the passenger cabin to reach thermal comfort, and the heating efficiency of the passenger cabin is low. SUMMARY

[0005] The present application discloses a heating control method and device, which can realize rapid heating of the passenger cabin in the vehicle and improve the comfort of the passenger cabin.

[0006] In a first aspect, the present application provides a heating control method, which comprises: first, obtaining reference information, the reference information including at least one of ambient temperature information and user's setting information, the ambient temperature information including the ambient temperature outside the vehicle and the current temperature of the passenger cabin inside the vehicle, the vehicle being deployed with an air conditioner and a target heater, the user's setting information including the user's setting of one or more of the expected temperature of the passenger cabin, the control parameter of the air conditioner, the control parameter of the target heater, and the first scenario mode of the vehicle, the target heater including at least one of a contact heater and a radiation heater, the contact heater being a heating hardware that transfers heat to the contacted object in the form of heat conduction, and the radiation heater being a heating hardware that transfers heat in the form of heat radiation; and then, controlling the air conditioner and the target heater to heat the passenger cabin according to the reference information.

[0007] The expected temperature of the passenger cabin refers to the ideal temperature that the user expects the passenger cabin to reach through heating control. The first scenario mode refers to the scenario mode currently set by the user. Illustratively, the scenario mode includes at least one of the camping mode, the rest mode, the energy-saving mode, the defrosting mode, the defogging mode, etc.

[0008] Exemplarily, the contact heater is usually installed in a seat of the vehicle, in a steering wheel, in a door panel armrest, or the like; and the radiation heater can be installed below or beside a seat in the vehicle, on a roof of the vehicle, on a side of a door panel, under a lower guard of the vehicle, or the like.

[0009] In the method, the air conditioner and the target heater can be controlled in linkage based on the reference information to jointly heat the passenger cabin. Compared with the heating by only turning on the air conditioner, the passenger cabin can be rapidly heated, so that the occupant in the passenger cabin can rapidly reach thermal comfort, and the ride comfort of the vehicle is improved. In addition, the reference information includes environmental temperature information and / or user setting information, the setting preferences of the user are considered, the decision of the heating control based on the reference information can be more scientific and accurate in different scenarios, which is not only beneficial to improve the comfort, but also can realize the effects of saving energy, optimizing NVH performance, ensuring fast charging rate, improving driving safety, and the like in the corresponding scenarios.

[0010] In a possible implementation form of the first aspect, the heat source providing component used by the air conditioner is different from the contact heater and the radiation heater.

[0011] Here, the heat source providing component used by the air conditioner can be a heat pump, an engine, or an electric heater, the contact heater serves as its own heat source providing component, the radiation heater serves as its own heat source providing component, and the contact heater and the radiation heater do not share the power of the air conditioner. By controlling the air conditioner and the target heater to heat the passenger cabin, compared with the heating of the passenger cabin by only controlling the air conditioner, the heating rate of the passenger cabin can be improved, and the comfort of the passenger cabin can be improved.

[0012] In a possible implementation form of the first aspect, the regulation parameter of the air conditioner includes at least one of the following:

[0013] an air outlet temperature of the air conditioner;

[0014] an air volume of the air conditioner; and

[0015] an air volume distribution ratio of the air conditioner.

[0016] The heating gear of the air conditioner is used to indicate the heating intensity of the air conditioner, and represents the ability or degree of the air conditioner to output heat when the air conditioner performs heating. Here, under other conditions, the higher the heating gear of the air conditioner, the stronger the heating intensity of the air conditioner, the more heat can be provided, and the faster the temperature rise rate of the passenger compartment. Under other conditions, the higher the air outlet temperature of the air conditioner, the faster the temperature rise rate of the passenger compartment. Under other conditions, the greater the air volume of the air conditioner, the stronger the air flow in the passenger compartment, and the faster the temperature change in the cabin. The air volume distribution ratio of the air conditioner is used to indicate the regional distribution of the air volume blown by the air conditioner in the vehicle, and the air volume distribution ratio of the air conditioner will affect the time for the passenger compartment to reach comfort and will also affect the defrosting effect in the defrosting mode or the defogging effect in the defogging mode.

[0017] In a possible implementation of the first aspect, the regulation parameter of the contact heater includes a heating gear of the contact heater, or the heating gear of the contact heater and a surface temperature of an interior trim part where the contact heater is located.

[0018] The heating gear of the contact heater is used to indicate the heating intensity of the contact heater. Under other conditions, the higher the heating gear of the contact heater, the stronger the heating intensity of the contact heater, the more heat can be provided, and the faster the temperature rise rate of the passenger compartment. Under other conditions, the higher the surface temperature of the interior trim part where the contact heater is located, the faster the temperature rise rate of the passenger compartment.

[0019] In a possible implementation of the first aspect, the regulation parameter of the radiation heater includes a heating gear of the radiation heater, or the heating gear of the radiation heater and a surface temperature of an interior trim part where the radiation heater is located.

[0020] The heating gear of the radiation heater is used to indicate the heating intensity of the radiation heater. Under other conditions, the higher the heating gear of the radiation heater, the stronger the heating intensity of the radiation heater, the more heat can be provided, and the faster the temperature rise rate of the passenger compartment. Under other conditions, the higher the surface temperature of the interior trim part where the radiation heater is located, the faster the temperature rise rate of the passenger compartment.

[0021] In a possible implementation of the first aspect, according to the reference information, the air conditioner and the target heater are controlled to heat the passenger compartment, including: in the case that the environmental temperature information satisfies a first condition, the air conditioner and the target heater are controlled to heat the passenger compartment, the first condition being a condition that the vehicle has a rapid temperature rise demand.

[0022] In this embodiment, the environmental information satisfies the first condition, which indicates that the vehicle currently has a rapid heating demand. In this case, the control device simultaneously controls the air conditioner and the target heater to heat the passenger compartment. The higher the heating gear of the air conditioner and the target heater, the better. The more the target heater includes the number of heaters, the better. In this way, the heating rate of the passenger compartment can be accelerated, and the occupant can obtain thermal comfort as soon as possible in a cold environment.

[0023] In a possible implementation of the first aspect, in a case where the environmental temperature information satisfies the first condition, the heating gear of the air conditioner is set to the highest gear, and the heating gear of the target heater is set to the highest gear.

[0024] In this embodiment, when the vehicle has a rapid heating demand, the air conditioner and the target heater heat the passenger compartment at the highest heating gear, which can rapidly increase the heating rate of the passenger compartment, so that the occupant can obtain thermal comfort as soon as possible in a cold environment.

[0025] In a possible implementation of the first aspect, the reference information further includes state information of the vehicle, and the state information of the vehicle includes at least one of a heat source providing mode of the air conditioner, a working demand of the vehicle, and a second scenario mode of the vehicle. The method further includes: controlling the air conditioner and the target heater to heat the passenger compartment according to the reference information, including: controlling the air conditioner and the target heater to heat the passenger compartment according to the environmental temperature information and the state information of the vehicle.

[0026] Here, the second scenario mode can be a scenario mode set by the user in the last history, or can be a scenario mode by default of the system.

[0027] The heat source providing mode of the air conditioner is different, and the corresponding energy consumption is different. For example, the energy consumption of an electric heater for heating is greater than that of a heat pump for heating, and the energy consumption of the electric heater is greater than that of the engine waste heat for heating. The working demand of the vehicle can include not only the heating of the passenger compartment, but also the charging of the vehicle battery. When the working demand of the vehicle includes the charging of the vehicle battery, for a vehicle that shares the same heat source with the air conditioner and the vehicle battery, there is heat distribution between the air conditioner and the vehicle battery. When the vehicle battery is also heated, it will affect the heating control of the air conditioner. Different scenario modes of the vehicle can have different control requirements, which can affect the decision of the heating control. Here, the heating control decision is made in combination with the environmental temperature information and the state information of the vehicle, which can improve the accuracy and practicality of the decision.

[0028] In a possible implementation of the first aspect, the heating of the passenger compartment by the air conditioner and the target heater is controlled according to the ambient temperature information and the state information of the vehicle, including: determining a target heating scheme according to the ambient temperature information and the state information of the vehicle, the target heating scheme including settings of a control parameter of the air conditioner and a control parameter of the target heater; and controlling the air conditioner and the target heater to heat the passenger compartment according to the target heating scheme.

[0029] Implementing this implementation, the ambient temperature information and the state information of the vehicle are combined to determine a target heating scheme to control the air conditioner and the target heater to jointly heat, which can scientifically and accurately perform heating in different scenarios, which is not only beneficial to improve comfort, but also can save energy consumption, optimize NVH performance, ensure fast charging rate, improve driving safety, and the like in corresponding scenarios.

[0030] In a possible implementation of the first aspect, the target heating scheme is a heating scheme with minimum total power in multiple heating schemes that meet the first comfort condition, and the total power is the sum of powers of the air conditioner and the target heater.

[0031] Implementing this implementation, the comfort and energy consumption are considered when determining the target heating scheme, which can improve the comfort of the passenger compartment while reducing the energy consumption of the vehicle.

[0032] In a possible implementation of the first aspect, the state information of the vehicle meets an energy consumption priority condition, and the energy consumption priority condition includes any one of the following conditions:

[0033] The second scenario mode is an energy saving mode.

[0034] The heat source providing mode of the air conditioner includes an electric heater.

[0035] The heat source providing mode of the air conditioner is a heat pump, and a performance coefficient of the heat pump meets a high efficiency condition; or

[0036] The heat source providing mode of the air conditioner is engine waste heat.

[0037] This implementation provides the prerequisite condition for determining the target heating scheme by using the energy consumption priority, which enriches the application scenarios.

[0038] In a possible implementation manner of the first aspect, when the heat source providing mode of the air conditioner comprises the electric heater, the target heating scheme is the first heating scheme; when the heat source providing mode of the air conditioner satisfies a second condition, the target heating scheme is the second heating scheme, and the second condition is any one of the following conditions: the heat source providing mode of the air conditioner is the heat pump and a coefficient of performance of the heat pump satisfies a high-efficiency condition; or, the heat source providing mode of the air conditioner is the engine waste heat; wherein the heating gear of the air conditioner in the first heating scheme is lower than the heating gear of the air conditioner in the second heating scheme, and the heating gear of the target heater in the first heating scheme is higher than the heating gear of the target heater in the second heating scheme.

[0039] In this implementation manner, the power consumption of the electric heater is greater than the power consumption of the heat pump, and the power consumption of the electric heater is also greater than the power consumption of the engine waste heat. In the case where other parameters (that is, the ambient temperature and the cabin temperature) are unchanged, compared with the case where the air conditioner uses the heat pump or the engine waste heat for heating, in the target heating scheme obtained when the air conditioner uses the electric heater for heating, the heating gear of the air conditioner is set to be lower, and the heating gear of the target heater is set to be higher.

[0040] In a possible implementation manner of the first aspect, the vehicle is provided with a vehicle battery, the heat source providing component used by the vehicle battery is the heat source providing component used by the air conditioner; in the case where the working demand of the vehicle comprises vehicle battery charging and passenger cabin heating, the heating power of the air conditioner is less than the heating power of the vehicle battery, and the target heating scheme makes the vehicle battery satisfy a charging rate condition and the passenger cabin satisfy a second comfort condition.

[0041] In this implementation manner, in the case where the working demand of the vehicle comprises vehicle battery charging and passenger cabin heating, when the air conditioner and the vehicle battery use the same heat source providing component, most of the heat can be used for heating the vehicle battery to maximize the charging rate of the vehicle battery, and the comfort of the passenger cabin can be improved by controlling at least one of the contact heater and the radiation heater to heat the passenger cabin, compared with the prior art in which the comfort of the passenger cabin or the charging rate is sacrificed when the vehicle battery and the passenger cabin have heating demands at the same time, the comfort requirement can be met and the fast charging rate can be ensured.

[0042] In a possible implementation manner of the first aspect, in the case where the second scenario mode is the camping mode or the break mode, the air outlet temperature of the air conditioner is greater than a temperature threshold, and the target heating scheme is a heating scheme in which the air volume of the air conditioner is the smallest in a plurality of heating schemes that make the passenger cabin satisfy a third comfort condition, or the target heating scheme makes the passenger cabin satisfy the third comfort condition and the air volume of the air conditioner is less than an air volume threshold.

[0043] As an example, in the case that the second scenario mode is the camping mode or the nap mode, in the target heating scheme, the air outlet temperature of the air conditioner is set to the maximum value, the air volume of the air conditioner is set to the minimum value, and the heating gear of the target heater is set to the highest gear.

[0044] In this implementation, in the case that the scenario mode is the camping mode or the nap mode, the air volume of the air conditioner is reduced as much as possible to improve the NVH performance of the vehicle, and the heating intensity of the target heater is also increased, so that the thermal comfort of the passenger compartment is improved.

[0045] In a possible implementation of the first aspect, in the case that the second scenario mode is the defrosting mode or the defogging mode, the proportion of the air volume of the air conditioner acting on the glass of the vehicle is greater than the proportion of the air volume of the air conditioner acting on the seated passengers, and the target heating scheme is such that the passenger compartment satisfies the fourth comfort condition.

[0046] As an example, in the case that the second scenario mode is the defrosting mode or the defogging mode, in the target heating scheme, the air volume distribution proportion of the air volume of the air conditioner acting on the glass of the vehicle is set to the maximum value, the air volume distribution proportion of the air volume of the air conditioner acting on the seated passengers is set to the minimum value, the heating gear of the air conditioner is set to the highest gear, the air outlet temperature of the air conditioner is set to the maximum value, and the heating gear of the target heater is set to the highest gear.

[0047] In this implementation, in the case that the scenario mode is the defrosting mode, most of the air volume of the air conditioner is used for defrosting, and a small part of the air volume is used for blowing, so that the defrosting effect is maximized to ensure the driving safety; in the case that the scenario mode is the defogging mode, most of the air volume of the air conditioner is used for defogging, and a small part of the air volume is used for blowing, so that the defogging effect is maximized to ensure the driving safety. In addition, the heating intensity of the target heater is also increased, so that the thermal comfort of the passenger compartment is improved.

[0048] In a possible implementation of the first aspect, the air conditioner and the target heater are controlled to heat the passenger compartment according to the environmental temperature information and the state information of the vehicle, including: the air conditioner and the target heater are controlled to heat the passenger compartment according to the environmental temperature information, the state information of the vehicle, and the setting information of the user.

[0049] In this implementation, the heating control decision is made based on the environmental temperature information, the state information of the vehicle, and the setting information of the user, so that the air conditioner and the target heater can be more accurately and scientifically controlled to perform heating, and the user experience is improved.

[0050] In a possible implementation of the first aspect, the reference information further includes member distribution information, the member distribution information being used to indicate a position area of the seated passengers in the passenger compartment, and the air conditioner and the target heater act on the position area where the seated passengers are located.

[0051] By implementing this implementation manner, the target area (i.e., the position area where the occupant is located) can be precisely heated by the member distribution information, so that the occupant in the area can feel hot and comfortable more quickly, which is beneficial to improving the temperature rising rate of the target area and saving the power consumption of the whole vehicle.

[0095] For the convenience of understanding, the related terms and the like that can be involved in the present scheme will be introduced first.

[0096] The NVH of a vehicle is a comprehensive evaluation index for measuring the quality of automobile manufacturing, and the feeling brought to the user is also the most direct.

[0097] NVH is the initials of the three English words of Noise, Vibration and Harshness. Among them, the noise in NVH mainly includes powertrain noise, road noise, wind noise and accessory noise in the vehicle, acceleration through noise and prompt sound outside the vehicle; vibration refers to the vibration of vehicle parts that can be perceived by the occupants, such as including steering wheel, seat, floor, shift lever, instrument table, door panel and rearview mirror; harshness refers to the intuitive feeling of people to sound, which is related to the transient nature of noise and vibration, and can also be understood as unevenness and impact characteristics.

[0098] The NVH performance of a vehicle can be a subjective evaluation. By damping and noise reduction, the NVH performance of the whole vehicle can be improved.

[0099] Predicted mean vote (PMV) is an objective evaluation index of thermal environment comfort in the passenger compartment of a vehicle. PMV can also be referred to as predicted mean thermal sensation index or predicted mean vote. Thermal environment comfort can be referred to as thermal comfort. Thermal comfort is the state of consciousness in which a person is satisfied with the thermal environment. Factors affecting human thermal comfort mainly include environmental factors and human factors. Environmental factors mainly include air temperature, mean radiant temperature, air flow rate, air relative humidity, etc. Human factors include human metabolism and clothing thermal resistance.

[0100] PMV is an objective evaluation of thermal comfort based on test environment parameters (such as temperature, wind speed, radiation, humidity, etc.). The results have good stability and consistency.

[0101] The heat source providing mode of the air conditioner includes heat pump, engine waste heat and electric heater. The principle of each heat source providing mode is described below.

[0102] (1) Heat pump: using the principle of reverse thermodynamic cycle, heat transfer is realized by compressing and expanding refrigerant. In the cooling mode, the heat pump absorbs heat from indoor air and releases it to the outdoor environment; in the heating mode, it absorbs heat from the outdoor environment and releases it to the indoor space.

[0103] (2) Engine waste heat: the engine generates a large amount of heat when it is working. The combustion of fuel in the engine, the friction between the parts in the engine, etc. cause heat generation, and the waste heat refers to the excess heat generated by the engine of the vehicle when it is working, which is not completely converted into mechanical energy. The heat exchanger can use this waste heat to heat the passenger compartment of the vehicle.

[0104] (3) Electric heater: when the electric heater is connected to the power supply, the electric current passes through the heating element in the electric heater, and the heating element has a certain resistance. When the electric current passes through the resistance, heat is generated, so the electric heater generates heat.

[0105] Exemplarily, the electric heater can be a positive temperature coefficient (PTC) electric heater, a high-voltage electric heater, a low-voltage electric heater, or the like. Taking the PTC electric heater as an example, the PTC is to use a PTC material as a heating element, and the PTC material has a positive temperature coefficient characteristic, that is, its resistance increases with the increase of temperature. The PTC material can be a ceramic material such as barium titanate (BaTiO3) or the like.

[0106] The engine waste heat and the electric heater described above both belong to a non-heat pump heating mode. Among the three heat source providing modes described above, the heat pump heat source providing mode can utilize the natural heat in the environment to transfer heat energy (for example, heating or refrigeration), and therefore, the heat pump generally has higher energy efficiency than the non-heat pump heating mode.

[0107] There are three ways of heat transfer, namely, heat convection, heat conduction, and heat radiation.

[0108] Among them, heat convection refers to the process of transferring heat through the flow of fluid (such as gas or liquid). In this process, heat is transferred from one region to another through the flow of fluid. Heat convection is divided into natural convection and forced convection, wherein natural convection refers to the spontaneous movement of fluid caused by density difference, resulting in convection. In natural convection, hot fluid rises and cold fluid sinks, forming a convection cycle. Forced convection refers to the process of enhancing convection by external devices (such as fans, pumps) to push fluid flow, and forced convection can accelerate heat transfer.

[0109] Heat radiation refers to the electromagnetic wave radiation caused by heat, and the intensity and wavelength of radiation are related to the temperature of the object. Heat radiation refers to the heat transfer mode in which an object emits heat energy in the form of electromagnetic radiation. Heat radiation occurs independently of any external conditions, and objects with a temperature higher than absolute zero can produce heat radiation. The higher the temperature, the more total energy is radiated, and the more short-wave components are produced.

[0110] Heat conduction refers to the process of transferring heat from a high-temperature region to a low-temperature region through direct contact between substances. Heat conduction mainly occurs in solids, but can also occur in liquids and gases. Compared with heat convection and heat radiation, heat conduction occurs between substances in contact.

[0111] The above-mentioned terms can be optionally applied in the embodiments below.

[0112] The heating control system can control at least one of the contact heater and the radiation heater and the air conditioner to heat the passenger cabin of the vehicle at the same time when the vehicle has a rapid heating demand, compared with the heating mode of only starting the air conditioner, the rapid heating of the passenger cabin can be realized, the heat comfort of the passengers in the passenger cabin is quickly reached, and the riding comfort of the vehicle is improved. In addition, the heating control system can also determine the optimal heating scheme in the current state in combination with the setting information of the user, the state information of the vehicle, the environmental temperature information and the like, and control at least one of the contact heater and the radiation heater and the air conditioner to execute heating based on the optimal heating scheme, so as to meet the heating demand in different states. In this way, more scientific and accurate heating is realized in different scenes, which is not only beneficial to improve the comfort, but also beneficial to save energy consumption, optimize NVH performance and the like.

[0113] The composition of the heating control system will be introduced below. Referring to FIG. 1A, FIG. 1A is an architecture schematic diagram of a heating control system provided by an embodiment of the present application. As shown in FIG. 1A, the heating control system includes a control device and a plurality of heating devices, wherein the plurality of heating devices includes at least one of a contact heater and a radiation heater and an air conditioner. Any one of the contact heater, the radiation heater and the air conditioner can communicate with the control device in a wired and / or wireless manner.

[0114] In an implementation manner, the control device and the plurality of heating devices are both arranged in a terminal.

[0115] Exemplarily, the terminal can include a vehicle, a ship, a steamship and the like transportation tool having a passenger cabin. Exemplarily, the vehicle can be a car, a sport utility vehicle, a commercial vehicle, a pickup truck, a van, a public transportation tool (such as a bus, a tram and the like) and the like.

[0116] Here, the vehicle can be an autonomous vehicle, which is configured with an autonomous driving system. The autonomous driving system can independently perform all or part of the driving operation according to different autonomous driving capabilities. In some possible embodiments, the vehicle can also be a non-autonomous vehicle, that is, the natural driver needs to perform all the driving operations.

[0117] Here, the vehicle can be a new energy vehicle, which can be an electric vehicle (EV), a hybrid electric vehicle (HEV), a range extended EV, a plug-in HEV, a fuel cell vehicle or other new energy vehicle.

[0118] Exemplarily, the control device can be a component within the terminal, such as a chip, an integrated circuit, a device, etc. When the terminal is a vehicle, the control device can be a controller, a vehicle integrated unit (VIU), a central computing unit, etc. on the vehicle. Exemplarily, the controller can be a software and hardware integrated platform for providing in-vehicle multimedia services, such as at least one of a heads-up display, a dashboard display, entertainment video, etc., e.g., a cockpit domain controller (CDC).

[0119] A contact heater is a heating hardware that transmits heat to a contacted object (e.g., a human body) in a heat conduction manner. The contact heater can use electric energy to provide heat. Exemplarily, the contact heater is usually installed in a seat, a steering wheel, a door panel armrest, etc. of a vehicle.

[0120] A radiant heater is a heating hardware that transmits heat in a heat radiation manner. The radiant heater can use electric energy to provide heat. Exemplarily, the radiant heater can be installed under or beside a seat in a vehicle, a roof of a vehicle, a side of a door panel, a lower guard of a vehicle, etc.

[0121] An air conditioner is a device that adjusts the temperature, humidity, and circulation of air in a vehicle in a heat convection manner, aiming to provide a comfortable driving and riding environment. The air conditioner uses the principle of air convection to heat the air in the passenger compartment, and can provide a uniform warm air effect.

[0122] Here, the number of installations of the above-mentioned air conditioner, contact heater, and radiant heater is not limited.

[0123] For example, the number of air conditioners usually depends on the type and configuration of the vehicle. A basic vehicle model usually has only one single-zone air conditioner for controlling the temperature of the entire vehicle. To achieve precise temperature control, a dual-zone air conditioner can be deployed, i.e., an air conditioner is provided for the driver seat and the front passenger seat, respectively; or a triple-zone air conditioner can be provided, i.e., an air conditioner is provided for the front row and the rear row of the passenger compartment, respectively. In some high-end vehicle models, an air conditioner can also be provided for each seat area in the front row and the rear row. For example, for the contact heater, one contact heater can be provided in each seat, or a contact heater can be provided in part of the seats, or multiple contact heaters can be provided in the same seat.

[0124] The heating control system shown in FIG. 1A can be applied in various application scenarios, such as the following application scenarios: mobile internet (MI), industrial control, self driving, transportation safety, internet of things (IoT), and the like.

[0125] The heating control system shown in FIG. 1A can be applied in various network types, such as one or more of the following network types: SparkLink, long term evolution (LTE) network, 5th generation mobile communication technology (5G), wireless local area network (for example, Wi-Fi), bluetooth (BT), Zigbee, or vehicle-mounted short-range wireless communication network, and the like.

[0126] It should be noted that FIG. 1A is only an exemplary architecture diagram, but does not limit the number of network elements included in the system shown in FIG. 1A. Although FIG. 1A does not show, in addition to the functional entities shown in FIG. 1A, the heating control system shown in FIG. 1A can also include other functional entities. In addition, the method provided in the present scheme can be applied to the heating control system shown in FIG. 1A, and of course the method provided in the present scheme can also be applicable to other heating control systems, such as FIG. 1B.

[0127] Referring to FIG. 1B, FIG. 1B is an architecture diagram of another heating control system provided by an embodiment of the present application. The heating control system shown in FIG. 1B includes a terminal and a network side device, and the terminal and the network side device are connected through a network, where the terminal can be the terminal in FIG. 1A.

[0128] The network side device is a device with computing capability. The network side device can be a server deployed on the network side (for example, a server for determining a heating scheme), or a component or chip in the server. In some schemes, the network side device can also be a system-level device or a cluster of computing devices composed of multiple servers. The network side device can be deployed in a cloud environment or in an edge environment.

[0129] Exemplarily, in FIG. 1B, the terminal and the network side device can interact, the control device of the terminal sends the locally obtained data information to the network side device to enable the network side device to analyze and determine a target heating scheme, and obtains a control instruction from the network side device, the control instruction including the target heating scheme, and the control device of the terminal controls the operation of the plurality of heating devices based on the control instruction.

[0130] Hereinafter, the terminal is exemplarily described by taking a vehicle as an example, but the terminal is not limited to the vehicle.

[0131] Referring to FIG. 2, FIG. 2 is a flowchart of a heating control method according to an embodiment of the present application. The method can be applied to the control device shown in FIG. 1A. Exemplarily, the control device is deployed on a vehicle. The method shown in FIG. 2 includes, but is not limited to, the following steps S201 and S202.

[0132] S201: Obtain reference information, the reference information including at least one of ambient temperature information and user setting information.

[0133] The ambient temperature information includes an ambient temperature outside the vehicle and a current temperature of a passenger compartment in the vehicle. The current temperature of the passenger compartment can also be referred to as an in-cabin temperature.

[0134] Exemplarily, the ambient temperature outside the vehicle is obtained from a first temperature sensor. The first temperature sensor can be installed near a front bumper or a rearview mirror of the vehicle, can detect an air temperature outside the vehicle, and can transmit the detected data to the control device.

[0135] Exemplarily, the in-cabin temperature of the passenger compartment in the vehicle is obtained from a second temperature sensor. The second temperature sensor can be installed near a central control panel, an air outlet of an air conditioner, or a roof area in the vehicle, can monitor an actual temperature in the vehicle, and can transmit the detected data to the control device.

[0136] In the present scheme, an air conditioner and a target heater are also deployed in the vehicle. The target heater includes at least one of a contact heater and a radiation heater. For the air conditioner, the contact heater, and the radiation heater, refer to the descriptions of the corresponding contents in the foregoing FIG. 1A, which will not be described herein again.

[0137] The heat source providing component used by the air conditioner is different from the contact heater and the radiation heater. The heat source providing component used by the air conditioner can be the heat pump, the engine, or the electric heater, while the contact heater and the radiation heater can both serve as their own heat source providing components, and the contact heater and the radiation heater both generate heat by using electric energy. It can be understood that the contact heater and the radiation heater do not share the power of the air conditioner.

[0138] In an implementation manner, the user setting information is obtained by receiving user input setting information. Here, the user can input the setting information by at least one of a touch screen, a button, a keyboard, and voice input. The user can be a seat occupant of the vehicle, a user of the vehicle, or the like.

[0139] The setting information of the user includes one or more of the following: a desired temperature of the passenger compartment, a control parameter of the air conditioner, a control parameter of the target heater, and a first scenario mode of the vehicle. The target heater includes at least one of a contact heater and a radiation heater. It can be understood that the setting information of the user reflects the setting preferences of the user and the current needs of the user, and the setting information of the user will greatly affect the decision of the controller on the heating scheme.

[0140] Here, the desired temperature of the passenger compartment refers to the ideal temperature that the user expects the passenger compartment to reach through heating control.

[0141] The first scenario mode refers to the scenario mode currently set by the user. For example, the scenario mode includes at least one of the following: a camping mode, a short rest mode, an energy saving mode, a defrosting mode, and a defogging mode.

[0142] The camping mode is a function used for long stays or camping, aiming to provide comprehensive comfort facilities and power support for the needs of overnight or long stays in the vehicle. The short rest mode is a function used for short rest or break, aiming to provide moderate comfort and convenience for the owner's short rest.

[0143] The energy saving mode has the longest endurance time of the vehicle.

[0144] The defrosting mode and the defogging mode are both functions to improve the clarity of vision, especially in cold and humid weather conditions. The defrosting mode refers to removing frost on the front windshield (or front window). The defogging mode refers to removing fog on the front windshield or side window. Both the defrosting mode and the defogging mode require warm air flow to achieve.

[0145] It can be understood that in the above camping mode and short rest mode, it is desired that the passenger compartment is as quiet as possible and the vehicle has as little vibration as possible. In the energy saving mode, it is desired that the energy consumption of the vehicle is as small as possible. In the defrosting mode and the defogging mode, it is desired that the rate of removing frost or fog is as fast as possible. It can be seen that the first scenario mode of the vehicle also affects the decision of the controller on the heating scheme.

[0146] The control parameters of the air conditioner, the contact heater, and the radiation heater are described below.

[0147] (1) Control parameter of the air conditioner

[0148] For example, the control parameter of the air conditioner includes at least one of the following:

[0149] The air outlet temperature of the air conditioner;

[0150] The air volume of the air conditioner; and

[0151] Air volume distribution ratio of the air conditioner.

[0152] The heating level, air volume, air outlet temperature, and air volume distribution ratio of the air conditioner are key parameters affecting the comfort of the passenger side.

[0153] The heating level of the air conditioner is used to indicate the heating intensity of the air conditioner, representing the ability or degree of heat output when the air conditioner performs heating. The heating level of the air conditioner affects the temperature rise rate of the passenger cabin. For example, the higher the heating level of the air conditioner, the stronger the heating intensity of the air conditioner, which can provide more heat, and under other conditions, the faster the temperature rise rate of the passenger cabin.

[0154] The air volume of the air conditioner refers to the amount of air blown by the air conditioner. The air volume of the air conditioner affects the flow rate of air in the passenger cabin, and in turn affects the change of the cabin temperature. The larger the air volume, the more intense the air flow, and the faster the cabin temperature changes.

[0155] The air outlet temperature of the air conditioner refers to the temperature of the air blown by the air conditioner. The air outlet temperature of the air conditioner affects the temperature rise rate of the passenger cabin. Under other conditions, the higher the air outlet temperature of the air conditioner, the faster the temperature rise rate of the passenger cabin.

[0156] The air volume distribution ratio of the air conditioner is used to indicate the regional distribution of the air volume blown by the air conditioner in the vehicle. Exemplarily, the air volume distribution regions include front window, central control, foot, rear row, etc. Different air volume distribution ratios of the air conditioner will affect the time length for the passenger cabin to reach a comfortable condition, and also affect the defrosting or demisting effect.

[0157] (2) Control parameters of the contact heater

[0158] Exemplarily, the control parameters of the contact heater include the heating level of the contact heater, or the heating level of the contact heater and the surface temperature of the interior part where the contact heater is located.

[0159] The heating level of the contact heater indicates the heating intensity of the contact heater. The heating intensity can be referred to the description of the corresponding content described above, which will not be repeated here. The surface temperature of the interior part where the contact heater is located affects the temperature rise rate of the passenger cabin. Under other conditions, the higher the surface temperature of the interior part where the contact heater is located, the faster the temperature rise rate of the passenger cabin.

[0160] (3) Control parameters of the radiation heater

[0161] Exemplarily, the control parameters of the radiation heater include the heating level of the radiation heater, or the heating level of the radiation heater and the surface temperature of the interior part where the radiation heater is located.

[0162] The heating level of the radiation heater indicates the heating intensity of the radiation heater. The surface temperature of the interior part where the radiation heater is located affects the temperature rising rate of the passenger cabin. When other factors remain unchanged, the higher the surface temperature of the interior part where the radiation heater is located, the faster the temperature rising rate of the passenger cabin.

[0163] The user inputs the setting information through the touch screen based on FIG. 3.

[0164] Referring to FIG. 3, FIG. 3 is a schematic diagram of a display interface for inputting setting information according to an embodiment of the present application. The interface shown in FIG. 3 is a human-computer interaction interface. In the user setting interface shown in FIG. 3, some configuration items for the expected temperature of the passenger cabin, the control parameters of the air conditioner, the control parameters of the contact heater, and the control parameters of the radiation heater are provided. The control parameters of the air conditioner, the control parameters of the contact heater, and the control parameters of the radiation heater each correspond to a selection box. For example, when the selection box corresponding to the control parameter setting of the air conditioner is selected by the user, it means that the data input by the user in the configuration item under the control parameter setting of the air conditioner is effective.

[0165] In FIG. 3, the configuration items under the control parameter setting of the air conditioner include the selection box of the heating level, the input box of the air outlet temperature, and the input box of the air volume; the configuration items under the control parameter setting of the contact heater include the selection box of the heating level and the input box of the surface temperature; and the configuration items under the control parameter setting of the radiation heater include the selection box of the heating level and the input box of the surface temperature. The user can freely select which control parameters to set.

[0166] In FIG. 3, when the user inputs “20℃” in the input box of the expected temperature of the passenger cabin, selects the control parameter setting of the air conditioner and sets the heating level to “medium”, and selects the control parameter setting of the radiation heater and sets the heating level to “high”, and then clicks the “OK” key, in response to the operation, the setting information of the user is generated, which includes that the expected temperature of the passenger cabin is “20℃”, the heating level of the air conditioner is “medium”, and the heating level of the radiation heater is “high”. In this way, the control device obtains the setting information of the user.

[0167] The above FIG. 3 is only an example of the display interface for providing the user to input the setting information, and the display interface is not limited to the form shown in FIG. 3, and other display interfaces for the user to input the setting information can also be provided. In some possible embodiments, more or less information than currently shown can also be displayed in FIG. 3. For example, the configuration items under the "regulation parameter setting of the air conditioner" in FIG. 3 can also include multiple input boxes of "air volume proportion distribution", etc. For another example, the "heating gear" is not limited to be set through the selection box, and can also be set through the input box; the "outlet air temperature", "air volume" and "surface temperature" are not limited to be set through the input box, and can also be set through the selection box. For another example, the regulation parameter settings of the air conditioner, the contact heater and the radiant heater can also be presented through different display interfaces, and are not limited to be presented on the same display interface. In some solutions, the setting information of the user can also be input by the user through the hardware operation button.

[0168] By providing the user setting interface, the user can be supported to specify the temperature of the passenger cabin, and the user can be supported to set the content of the regulation parameters of the air conditioner, the contact heater and the radiant heater, which is beneficial to improve the user experience.

[0169] In some possible embodiments, the reference information can also include at least one of state information of the vehicle and member distribution information. Here, the state information of the vehicle and the member distribution information are both optional information in the reference information.

[0170] The state information of the vehicle is used to indicate the working state of the vehicle. As an example, the state information of the vehicle includes at least one of a heat source providing mode of the air conditioner, a working demand of the vehicle and a second scenario mode of the vehicle.

[0171] (1) Heat source providing mode of the air conditioner

[0172] Exemplarily, the heat source providing mode of the air conditioner includes at least one of the above electric heater, the heat pump and the engine waste heat.

[0173] Since the electric heater generates heat by resistance heating, the electric current is converted into heat energy when passing through the heating element, and the heat generation of the electric heater is the direct conversion of electric energy. The heat pump works by transferring heat, and the higher the coefficient of performance (COP) of the heat pump, the higher the energy of the heat pump, and the heat pump only needs to consume less electric energy to transfer a large amount of heat. The engine waste heat directly utilizes the waste heat generated during the operation of the engine, reducing the additional energy demand. Therefore, compared with the electric heater, the energy efficiency of the heat pump and the engine waste heat is higher, so the power consumption of the electric heater is greater than that of the heat pump, and the power consumption of the electric heater is also greater than that of the engine waste heat. Here, the power consumption can also be referred to as energy consumption. It can be seen that the air conditioner provides heat in different modes, and the corresponding energy consumption is different, which will affect the subsequent determination of the heating scheme by the control device.

[0174] (2) Working requirement of the vehicle

[0175] Exemplarily, the working requirement of the vehicle includes at least one of passenger cabin heating and vehicle battery charging. In the case that the vehicle is provided with a vehicle battery, the vehicle battery can have a charging requirement, and the vehicle battery is heated when charging to maintain a suitable temperature of the battery during charging, thereby improving the charging speed and rate, and heating the vehicle battery can also avoid the adverse effects of low temperature on the internal chemical reaction of the vehicle battery to prolong the service life of the battery.

[0176] And the heat source used by the air conditioner is the same as that used by the vehicle battery, and when both the air conditioner and the vehicle battery perform heating, there will be a competition for the heat source. It can be seen that the working requirement of the vehicle is different, and the proportion of heat allocated by the control device to the air conditioner and the vehicle battery will be different, which will also affect the subsequent determination of the heating scheme by the control device.

[0177] (3) Second scenario mode of the vehicle

[0178] Here, the second scenario mode can be the current scenario mode of the vehicle. The second scenario mode can be the scenario mode set by the user in the last time, or can be the system default scenario mode. The second scenario mode can be the same as or different from the above-mentioned first scenario mode. The second scenario mode can refer to the examples of the aforementioned scenario modes, which will not be repeated here.

[0179] The member distribution information is used to indicate the position area of the occupant in the passenger cabin. Since the above-mentioned air conditioner, contact heater and radiation heater can be installed in different areas of the passenger cabin, through the member distribution information, the control device can accurately control the heating of the heating device in the corresponding area, so that the occupant in the area can feel hot and comfortable faster.

[0180] Referring to FIG. 4, FIG. 4 is a processing schematic diagram of a control device according to an embodiment of the present application. In FIG. 4, the reference information that can be input to the control device is listed above the control device. In the present solution, the reference information not only includes the ambient temperature information, but also can include at least one of the user's setting information, the vehicle's state information and the member distribution information. The control device makes a decision based on the obtained reference information to determine the current heating scheme, and controls at least one of the contact heater and the radiation heater and the air conditioner to work based on the heating scheme. The decision process and result of the control device can refer to the description of S202 below.

[0181] S202: controlling the air conditioner and the target heater to heat the passenger cabin of the vehicle according to the reference information, the target heater including at least one of the contact heater and the radiation heater.

[0182] In an implementation manner, the controlling the air conditioner and the target heater to heat the passenger cabin according to the reference information includes: when the ambient temperature information satisfies a first condition, controlling the air conditioner and the target heater to heat the passenger cabin, where the first condition is a condition that the vehicle has a rapid temperature rising demand.

[0183] For example, the first condition is that the ambient temperature is less than a first temperature value and the cabin temperature is less than a second temperature value; or the first condition is that the ambient temperature is less than the first temperature value, the cabin temperature is less than the second temperature value, and the absolute value of the temperature difference between the ambient temperature and the cabin temperature is less than a first value.

[0184] Here, the first temperature value, the second temperature value and the first value are all preset based on experience.

[0185] For example, when the ambient temperature information satisfies the first condition, the controlling the air conditioner and the target heater to heat the passenger cabin includes: determining a first target heating scheme according to the ambient temperature information, the first target heating scheme being a heating scheme that enables the passenger cabin to achieve optimal comfort under the ambient temperature information, the first target heating scheme including the setting of the control parameters of the air conditioner and the target heater; and controlling the air conditioner and the target heater to heat the passenger cabin according to the first target heating scheme. Here, the comfort can be calculated by PMV, and the calculation method of PMV is relatively mature in the field of thermal comfort evaluation, and will not be described here.

[0186] It can be understood that when the ambient temperature information satisfies the first condition, the air conditioner and the contact heater can be controlled to perform heating, the air conditioner and the radiation heater can be controlled to perform heating, or the air conditioner, the contact heater and the radiation heater can be controlled to perform heating.

[0187] As an example, in the first target heating scheme, the heating level of the air conditioner is set to the highest level and the heating level of the target heater is set to the highest level. The heating level being set to the highest level means that the heating intensity reaches the maximum within the allowable range. Further, the surface temperature of the interior part where the target heater is located can also be set to the highest temperature.

[0188] Referring to Table 1, Table 1 shows some heating schemes based on the environmental temperature signal under the condition of having a rapid heating demand. It is assumed that the range of PMV comfort is from -4 (very cold) to +4 (very hot). In Table 1, the heating scheme under the condition of the environmental temperature being “-10°C” and the cabin temperature being “-10°C” is that the heating level of the air conditioner is set to “high”, the air outlet temperature of the air conditioner is set to “55”, the heating level of the radiant heater is set to “high”, the surface temperature of the interior part where the radiant heater is located is set to “70”, the heating level of the contact heater is set to “high”, and the surface temperature of the interior part where the contact heater is located is set to “43”, and the corresponding PMV comfort of the heating scheme is “-3”. In the existing scheme, the PMV comfort of the passenger compartment under the condition of the environmental temperature being “-10°C” and the cabin temperature being “-10°C” is “-4” when only the heating level of the air conditioner is set to “high” and the air outlet temperature is set to “55”, so compared with the existing scheme, not only the comfort of the passenger compartment can be improved, but also the time for the passenger compartment to reach the comfort is shortened.

[0189] As can be seen from Table 1, under the condition of the same environmental temperature, the lower the cabin temperature, the greater the possibility that the radiant heater and the contact heater are both turned on, and the higher the heating levels of the air conditioner, the radiant heater and the contact heater will be set.

[0190] Table 1: Heating schemes in the rapid heating stage

[0191] It can be understood that the settings of the heating level and the air outlet temperature of the air conditioner, the heating level and the surface temperature of the radiant heater, and the heating level and the surface temperature of the contact heater in the heating schemes shown in Table 1 are only examples and should not be construed as limiting the settings of the control parameters of the air conditioner, the radiant heater and the contact heater in the heating schemes under the environmental temperature information shown in Table 1, nor should it be construed as limiting the number of heating schemes shown in Table 1. In actual applications, the textual content and storage mode of the corresponding relationship recorded in Table 1 can also be in other forms, for example, the air volume of the air conditioner can also be recorded in Table 1.

[0192] As shown in FIG. 5A, when the ambient temperature information satisfies the first condition, it is indicated that the vehicle currently has a rapid heating demand, in which case, the control device determines the first target heating scheme based on the decision criterion of prioritizing comfort to simultaneously control the air conditioner and the target heater to heat the passenger compartment, and the more the target heater includes the number of heaters, the faster the heating rate of the passenger compartment can be accelerated, so that the occupants can obtain thermal comfort as soon as possible in a cold environment.

[0193] In an implementation, when the reference information further includes state information of the vehicle, the above-mentioned controlling the air conditioner and the target heater to heat the passenger compartment according to the reference information includes: controlling the air conditioner and the target heater to heat the passenger compartment according to the ambient temperature information and the state information of the vehicle. Here, the state information of the vehicle is described in the foregoing S201, which will not be described here.

[0194] Further, the above-mentioned controlling the air conditioner and the target heater to heat the passenger compartment according to the ambient temperature information and the state information of the vehicle includes: determining a second target heating scheme according to the ambient temperature information and the state information of the vehicle; and controlling the air conditioner and the target heater to heat the passenger compartment according to the second target heating scheme.

[0195] Considering that the state information of the vehicle is different, the decision criterion relied on by the control device when determining the second target heating scheme can be different. In this scheme, the possible decision criteria can be the following.

[0196] The first one: the decision criterion is energy consumption priority under the premise of meeting comfort

[0197] In an implementation, the above-mentioned determining the second target heating scheme according to the ambient temperature information and the state information of the vehicle includes: when the state information of the vehicle satisfies the energy consumption priority condition, determining a plurality of heating schemes that satisfy the first comfort condition of the passenger compartment according to the ambient temperature information and the state information of the vehicle; then, calculating the total power corresponding to each heating scheme in the plurality of heating schemes, the total power corresponding to each heating scheme being the sum of the power of the air conditioner and the target heater under the heating scheme; and finally, taking the heating scheme with the minimum total power as the second target heating scheme. That is, as shown in FIG. 5B, when the state information of the vehicle satisfies the energy consumption priority condition, the control device determines the second target heating scheme based on the decision criterion of prioritizing comfort and energy consumption, and the second target heating scheme is the heating scheme with the minimum total power in the plurality of heating schemes that satisfy the first comfort condition of the passenger compartment.

[0198] Exemplarily, the energy consumption priority condition can be any of the following conditions:

[0199] Condition 1: the first scenario mode is the energy saving mode;

[0200] Condition 2: the heat source providing mode of the air conditioner includes an electric heater;

[0201] Condition 3: the heat source providing mode of the air conditioner is a heat pump and the coefficient of performance of the heat pump satisfies a high-efficiency condition; or,

[0202] Condition 4: the heat source providing mode of the air conditioner is engine waste heat.

[0203] For Condition 2, the heat source providing mode of the air conditioner includes an electric heater, which can be that the heat source providing mode of the air conditioner is an electric heater, or the heat source providing mode of the air conditioner includes a heat pump and an electric heater and the coefficient of performance of the heat pump does not satisfy the high-efficiency condition.

[0204] In some schemes, the energy consumption priority condition can also be a condition obtained by combining Condition 1 and any one of the above Conditions 2, 3 and 4.

[0205] Here, the first comfort condition can be a comfort value set by the user in advance, can also be a comfort value set by the system by default, or can also be a comfort value based on environmental temperature information to make the passenger compartment reach maximum comfort. The second target heating scheme can be the same as the first target heating scheme, or can also be different.

[0206] Exemplarily, the high-efficiency condition can be that the coefficient of performance of the heat pump is greater than a performance threshold. The performance threshold is set in advance based on experience.

[0207] Here, the power of the air conditioner refers to the power used by the air conditioner for heating. The calculation of the power of the air conditioner involves multiple parameters, such as air density, specific heat capacity, temperature difference, heating gear of the air conditioner, air volume of the air conditioner, air outlet temperature of the air conditioner, heat source providing mode of the air conditioner, etc. Among them, the heating gear of the air conditioner affects the output of the power of the air conditioner, and the power of the air conditioner corresponding to different heat source providing modes under the same heating gear can be different. The greater the temperature difference, the more power the air conditioner needs to increase the cabin temperature to the preset value. The higher the air outlet temperature of the air conditioner, the more the power of the air conditioner will also increase accordingly.

[0208] For example, assuming that the heat source providing mode of the air conditioner is an electric heater, the ambient temperature is "-10°C", and the cabin temperature is "20°C", three heating schemes satisfying the first comfort condition are determined by calculation, which are heating scheme Al, heating scheme A2, and heating scheme A3 in Table 2 below, i.e., heating scheme Al, heating scheme A2, and heating scheme A3 can all achieve the same comfort, in which case, the total power corresponding to each heating scheme is calculated, and according to Table 2, the total power corresponding to heating scheme Al is "4.1 kw", the total power corresponding to heating scheme A2 is "3.9 kw", and the total power corresponding to heating scheme A3 is "3.7 kw", the total power corresponding to heating scheme A3 is the smallest, and therefore, heating scheme A3 is taken as the second target heating scheme when the heat source providing mode of the air conditioner is an electric heater, the ambient temperature is "-10°C", and the cabin temperature is "20°C".

[0209] Table 2 Heating schemes when the heat source providing mode of the air conditioner is an electric heater, the ambient temperature is "-10°C", and the cabin temperature is "20°C"

[0210] For example, assuming that the heat source providing mode of the air conditioner is an electric heater, the ambient temperature is "-10°C", and the cabin temperature is "20°C", three heating schemes satisfying the first comfort condition are determined by calculation, which are heating scheme Al, heating scheme A2, and heating scheme A3 in Table 2 below, i.e., heating scheme Al, heating scheme A2, and heating scheme A3 can all achieve the same comfort, in which case, the total power corresponding to each heating scheme is calculated, and according to Table 2, the total power corresponding to heating scheme Al is "4.1 kw", the total power corresponding to heating scheme A2 is "3.9 kw", and the total power corresponding to heating scheme A3 is "3.7 kw", the total power corresponding to heating scheme A3 is the smallest, and therefore, heating scheme A3 is taken as the second target heating scheme when the heat source providing mode of the air conditioner is an electric heater, the ambient temperature is "-10°C", and the cabin temperature is "20°C".

[0211] Table 3 Heating schemes when the heat source providing mode of the air conditioner is a heat pump, the ambient temperature is "-10°C", and the cabin temperature is "20°C"

[0212] In Table 3, when the heat source providing mode of the air conditioner is a heat pump, the ambient temperature is "-10°C", and the cabin temperature is "20°C", heating scheme Bl, heating scheme B2, and heating scheme B3 can all achieve the same comfort, among which, the total power corresponding to heating scheme B2 is the smallest, and therefore, heating scheme B2 is taken as the second target heating scheme when the heat source providing mode of the air conditioner is a heat pump, the ambient temperature is "-10°C", and the cabin temperature is "20°C".

[0213] Table 4 Heating schemes when the heat source providing mode of the air conditioner is engine waste heat, the ambient temperature is "-10°C", and the cabin temperature is "20°C"

[0214] In Table 4, under the conditions that the heat source providing mode is engine waste heat, the ambient temperature is "-10℃", and the cabin temperature is "20℃", heating scheme C1, heating scheme C2, and heating scheme C3 can all achieve the same comfort level, wherein the total power corresponding to heating scheme C1 is the smallest, and therefore heating scheme C1 is taken as the second target heating scheme when the heat source providing mode is engine waste heat, the ambient temperature is "-10℃", and the cabin temperature is "20℃".

[0215] Here, the above Tables 2-4 are only examples of some heating schemes for more clearly illustrating the present scheme, and should not constitute a limitation on the number of possible heating schemes shown in Tables 2-4, the setting of the regulating parameters of the air conditioner, the radiant heater, and the contact heater in the heating schemes under the ambient temperature information. In actual applications, the textual content and storage mode of the corresponding relationship recorded in Tables 2-4 can also be in other forms, for example, one or more of the air conditioner air volume and air outlet temperature, the surface temperature of the contact heater, and the surface temperature of the radiant heater can also be recorded.

[0216] Further, when the heat source providing mode of the air conditioner includes an electric heater, the second target heating scheme is the first heating scheme; when the heat source providing mode of the air conditioner satisfies the second condition, the second target heating scheme is the second heating scheme, and the second condition is the above condition 3 or condition 4; and the first heating scheme and the second heating scheme satisfy: the heating level of the air conditioner in the first heating scheme is lower than the heating level of the air conditioner in the second heating scheme, and the heating level of the target heater in the first heating scheme is higher than the heating level of the target heater in the second heating scheme.

[0217] As known from the foregoing, the power consumption of the electric heater is greater than the power consumption of the heat pump, and the power consumption of the electric heater is also greater than the power consumption of the engine waste heat. Under the condition that other parameters (i.e., the ambient temperature and the cabin temperature) remain unchanged, compared with the air conditioner using the heat pump or the engine waste heat for heating, when the air conditioner uses the electric heater for heating, the heating level of the air conditioner in the second target heating scheme obtained will be set to be lower, and the heating level of the target heater will be set to be higher.

[0218] Second: the decision criterion is to consider both comfort and fast charging rate

[0219] In an implementation, the vehicle further has a vehicle battery, and the heat source providing component used by the vehicle battery is the heat source providing component used by the air conditioner. The determining the second target heating scheme according to the ambient temperature information and the state information of the vehicle includes: in a case where the working requirement of the vehicle includes the passenger cabin heating and the vehicle battery charging, determining the second target heating scheme according to the ambient temperature information and the state information of the vehicle, the second target heating scheme satisfying a charging rate condition of the vehicle battery and a second comfort condition of the passenger cabin. In the second target heating scheme, the heating power of the air conditioner is less than the heating power of the vehicle battery. As shown in FIG. 5C, in a case where the working requirement of the vehicle includes the passenger cabin heating and the vehicle battery charging, the control device determines the second target heating scheme while considering the comfort and the fast charging rate.

[0220] For example, the charging rate condition can be that a time consumed for the vehicle battery to be fully charged is less than a first time, or the time consumed for the vehicle battery to be fully charged is the shortest. The charging rate condition can be preset based on experience or be a default setting of the system.

[0221] Here, the second comfort condition can be that a preset comfort value is reached, which can be set by a user or be a default setting of the system, or the second comfort condition can be that the comfort of the passenger cabin is as good as possible.

[0222] For example, in a case where the working requirement of the vehicle includes the vehicle battery charging and the passenger cabin heating, the second target heating scheme can be a heating scheme with the fastest charging rate among multiple heating schemes satisfying the second comfort condition of the passenger cabin.

[0223] For example, in a case where the working requirement of the vehicle includes the vehicle battery charging and the passenger cabin heating, the second target heating scheme can be a heating scheme with the best comfort among multiple heating schemes satisfying the charging rate condition of the vehicle battery.

[0224] For example, in a case where the working requirement of the vehicle includes the vehicle battery charging and the passenger cabin heating, in the second target heating scheme, the heating gear of the air conditioner is set to the lowest gear, and the heating gear of the target heater is set to the highest gear.

[0225] Referring to Table 5, Table 5 shows some heating schemes when the vehicle's working demand includes vehicle battery charging, assuming that the ambient temperature is "-20℃" and the cabin temperature is "0℃", and the total power of the air conditioner and the vehicle battery is 7kw. Three heating schemes are shown in Table 5, which are heating scheme D1, heating scheme D2 and heating scheme D3, wherein heating scheme D1 achieves the best comfort but the longest time required for the battery to be fully charged, heating scheme D2 and heating scheme D3 achieve the same comfort, and the time required for the battery to be fully charged is the shortest (meaning the highest fast charging rate) under heating scheme D2. Therefore, heating scheme D3 in Table 5 is the best and can be used as the second target heating scheme described above.

[0226] Table 5: Heating schemes in vehicle battery charging scenarios (ambient temperature is -20℃ and cabin temperature is 0℃)

[0227] It can be understood that Table 5 is only an example of heating schemes in vehicle battery charging scenarios, and should not be limited to the settings of the control parameters of the air conditioner, the radiant heater and the contact heater in the heating schemes shown in Table 5, nor should it be limited to the number of heating schemes. In actual applications, the textual content and storage method of the corresponding relationship recorded in Table 5 can also be in other forms, for example, Table 5 can also record information such as the air volume of the air conditioner, the air outlet temperature of the air conditioner, the surface temperature of the interior part where the contact heater and the radiant heater are located, etc.

[0228] It can be seen that the need for heating the passenger compartment indicates that the vehicle's working demand includes the demand for heating the passenger compartment. When the air conditioner and the vehicle battery use the same heat source to provide components, most of the heat can be used for heating the vehicle battery to maximize the charging rate of the vehicle battery, and in combination with controlling at least one of the contact heater and the radiant heater to heat the passenger compartment, the comfort of the passenger compartment can be improved. Compared with the prior art, when the vehicle battery and the passenger compartment have heating needs at the same time, the comfort of the passenger compartment or the charging rate needs to be sacrificed. This method can meet the comfort requirement and ensure the fast charging rate.

[0229] Third: the decision criterion is to consider comfort and NVH performance at the same time

[0230] In one implementation, the determining the second target heating scheme according to the ambient temperature information and the state information of the vehicle comprises: in a case where the second scenario mode of the vehicle is the camping mode or the rest mode, determining the second target heating scheme according to the ambient temperature information and the state information of the vehicle; wherein the second target heating scheme is a heating scheme in which the air volume of the air conditioner is the smallest in multiple heating schemes in which the passenger compartment meets the third comfort condition, or the second target heating scheme is a heating scheme in which the passenger compartment meets the third comfort condition and the air volume of the air conditioner is less than the air volume threshold. Further, in the second target heating scheme, the outlet air temperature of the air conditioner is greater than the temperature threshold.

[0231] That is, as shown in FIG. 5D, in a case where the scenario mode of the vehicle is the camping mode or the rest mode, the control device considers both comfort and NVH performance when determining the second target heating scheme.

[0232] Here, the air volume threshold can be pre-set based on experience.

[0233] Exemplarily, the third comfort condition is to reach a preset comfort value, which can be a user setting or a system factory default setting.

[0234] As an example, in a case where the second scenario mode of the vehicle is the camping mode or the rest mode, in the second target heating scheme, the outlet air temperature of the air conditioner is set to the maximum value, the air volume of the air conditioner is set to the minimum value, and the heating gear of the target heater is set to the highest gear. Further, the surface temperature of the interior trim part where the target heater is located is set to the maximum value.

[0235] Here, the greater the air volume of the air conditioner, the greater the noise generated, resulting in poorer NVH performance.

[0236] Referring to Table 6, Table 6 shows some heating schemes in the rest mode, assuming that the ambient temperature is “-20°C” and the cabin temperature is “0°C”. As can be seen, Table 6 shows three heating schemes, namely heating scheme E1, heating scheme E2 and heating scheme E3. Among them, heating scheme E1, heating scheme E2 and heating scheme E3 have the same PMV comfort, but the NVH performance evaluation of heating scheme E1 is “poor”, the NVH performance evaluation of heating scheme E2 is “acceptable”, and the NVH performance evaluation of heating scheme E3 is “excellent”. Therefore, heating scheme E3 in Table 6 is the best, which can be used as the above-mentioned second target heating scheme.

[0237] Table 6: Heating schemes in the rest mode scenario (ambient temperature is -20°C and cabin temperature is 0°C)

[0238] It can be understood that Table 6 is only an example of the heating scheme in the nap mode scenario, and should not be limited to the setting of the control parameters of the air conditioner, the radiation heater and the contact heater in the heating scheme shown in Table 6, nor should it be limited to the number of heating schemes. In actual applications, the text content and storage mode of the corresponding relationship recorded in Table 6 can also be other forms, for example, the surface temperature of the interior trim part where the contact heater and the radiation heater are located can also not be recorded in Table 6.

[0239] It can be seen that in the case where the scenario mode is the camping mode or the nap mode, the air volume of the air conditioner should be reduced as much as possible to improve the NVH performance of the vehicle, and in addition, the heating intensity of the target heater is also increased, so that the thermal comfort of the passenger compartment can be improved.

[0240] The fourth: the decision criterion is to consider comfort and driving safety (referring to defrosting effect or defogging effect)

[0241] In one implementation, the second target heating scheme is determined according to the environmental temperature information and the state information of the vehicle, including: in the case where the second scenario mode of the vehicle is the defrosting mode or the defogging mode, the second target heating scheme is determined according to the environmental temperature information and the state information of the vehicle; wherein the second target heating scheme makes the passenger compartment meet the fourth comfort condition, and in the second target heating scheme, the proportion of the air volume of the air conditioner acting on the glass of the vehicle is greater than the proportion of the air volume of the air conditioner acting on the seated passenger.

[0242] That is, as shown in FIG. 5E, in the case where the scenario mode of the vehicle is the defrosting mode or the defogging mode, the control device considers comfort and driving safety (referring to the defogging effect in the defogging mode or the defrosting effect in the defrosting mode) when determining the second target heating scheme.

[0243] Exemplarily, the fourth comfort condition can be to reach a preset comfort value or belong to a preset comfort range, and the preset comfort value or the preset comfort range can be a user setting or a system factory default setting.

[0244] As an example, in the case where the second scenario mode is the defrosting mode or the defogging mode, in the second target heating scheme, the air volume distribution ratio of the air volume of the air conditioner acting on the glass of the vehicle is set to the maximum value, the air volume distribution ratio of the air volume of the air conditioner acting on the seated passenger is set to the minimum value, the heating gear of the air conditioner is set to the highest gear, the air outlet temperature of the air conditioner is set to the maximum value, and the heating gear of the target heater is set to the highest gear. Further, the surface temperature of the interior trim part where the target heater is located is set to the highest temperature.

[0245] Referring to Table 7, Table 7 shows some heating schemes in defrosting mode, assuming that the ambient temperature is “-20℃” and the cabin temperature is “0℃”. It can be seen that Table 7 shows three heating schemes, heating scheme F1, heating scheme F2 and heating scheme F3. Among them, heating scheme F1, heating scheme F2 and heating scheme F3 achieve the same PMV comfort, but the defrosting effect of heating scheme F1 is “poor”, the defrosting effect of heating scheme F2 is “acceptable”, and the defrosting effect of heating scheme F3 is “good”. Therefore, heating scheme F3 in Table 7 is optimal and can be used as the second target heating scheme described above. In heating scheme F3, the heating level of the air conditioner is “high”, the air volume distribution ratio of the air conditioner for defrosting is “90%” and the air volume distribution ratio for blowing (such as face blowing, foot blowing, etc.) is “10%”, the heating level of the contact heater is “high” and the surface temperature is “43”, and the heating level of the radiant heater is “high” and the surface temperature is “70”.

[0246] Table 7 Heating scheme in defrosting mode (ambient temperature is -20℃ and cabin temperature is 0℃)

[0247] It can be understood that Table 7 is only an example of a heating scheme in a defrosting mode scenario, and should not be limited to the settings of the air conditioner, radiant heater and contact heater in the heating scheme shown in Table 7, nor should it be limited to the number of heating schemes. In actual applications, the textual content and storage method of the corresponding relationship recorded in Table 7 can also be in other forms, for example, the air outlet temperature, air volume, etc. of the air conditioner can also be recorded in Table 7.

[0248] It can be seen that in the scenario mode of defrosting mode, most of the air volume of the air conditioner is used for defrosting, and a small part of the air volume is used for blowing, which can maximize the defrosting effect and ensure driving safety; In the scenario mode of defrosting mode, most of the air volume of the air conditioner is used for defrosting, and a small part of the air volume is used for blowing, which can maximize the defrosting effect and ensure driving safety. In addition, the heating intensity of the target heater is also increased, which can improve the thermal comfort of the passenger compartment.

[0249] In some possible embodiments, the second target heating scheme is determined according to the ambient temperature information and the state information of the vehicle, including: determining the second target heating scheme according to the ambient temperature information, the state information of the vehicle and the user's setting information. It can be understood that when the first scenario mode in the user's setting information is different from the second scenario mode in the state information of the vehicle, the first scenario mode is used as the reference.

[0250] As an example, when the user's setting information includes a desired temperature of the passenger cabin set by the user, a regulation parameter of the air conditioner, a regulation parameter of the target heater, and the first scenario mode described above, the second target heating scheme is determined according to the environmental temperature information, the state information of the vehicle, and the user's setting information, including: determining a heating scheme one according to the environmental temperature information, the state information of the vehicle, the first scenario mode, and the desired temperature of the passenger cabin; determining a heating scheme two according to the environmental temperature information, the state information of the vehicle, and the user's setting information; when the heating scheme two is different from the heating scheme one, taking the heating scheme two as the second target heating scheme. This embodiment shows that when the user's setting information includes the regulation parameters of both the air conditioner and the target heater, the heating scheme determined based on the regulation parameters of the air conditioner and the target heater set by the user is preferentially selected, which fully considers the control intention of the user and improves the user experience.

[0251] In some schemes, when the heating scheme two is different from the heating scheme one, the heating scheme one and the heating scheme two can also be displayed to the user to enable the user to select one of the heating scheme one and the heating scheme two, where the heating scheme one is the optimal heating scheme recommended by the system, and the heating scheme two is determined based on the regulation parameters of both the air conditioner and the target heater set by the user; the heating scheme selected by the user is taken as the second target heating scheme. Sometimes, the regulation parameters of the air conditioner and the target heater set by the user can not be optimal, resulting in that the corresponding heating scheme two is not the optimal heating scheme at present. By implementing this scheme, the user can be informed of this situation, and the user is given the opportunity to select the heating scheme, which can guide the user to select the optimal heating scheme, thereby improving the accuracy of the heating control decision and improving the user experience.

[0252] In some possible embodiments, the air conditioner and the target heater are controlled to heat the passenger cabin of the vehicle according to the reference information, including: controlling the air conditioner and the target heater to heat the passenger cabin according to the user's setting information.

[0253] Exemplarily, when the user's setting information only includes a desired temperature of the passenger cabin, the air conditioner and the target heater are controlled to heat the passenger cabin according to the user's setting information, including: determining that the desired temperature of the passenger cabin belongs to a first temperature range according to mapping information, and obtaining a heating scheme corresponding to the first temperature range from the mapping information; and controlling the air conditioner and the target heater to heat the passenger cabin based on the heating scheme corresponding to the first temperature range, where the mapping information includes the first temperature range and the heating scheme corresponding to the first temperature range.

[0254] For example, the heating scheme corresponding to the first temperature range at least includes target heaters to be turned on, heating levels of the target heaters, and a heating level of the air conditioner. In the mapping information, the heating schemes corresponding to different temperature ranges can be different. For example, the heating scheme 1 corresponding to the temperature range 1 and the heating scheme 2 corresponding to the temperature range 2 can be different. In some schemes, in the case that the minimum value of the temperature range 1 is greater than the maximum value of the temperature range 2, the heating level of the air conditioner in the heating scheme 1 is higher than the heating level of the air conditioner in the heating scheme 2, and the heating level of the target heater in the heating scheme 1 is higher than the heating level of the target heater in the heating scheme 2.

[0255] Exemplarily, when the setting information of the user includes at least one of a setting of a user-controlled parameter of the air conditioner, a user-controlled parameter of the target heater, and a first scenario mode of the vehicle, and a desired temperature of the passenger compartment, a third target heating scheme is determined according to the setting information of the user, and the air conditioner and the target heater are controlled to heat the passenger compartment according to the third target heating scheme.

[0256] Here, if the user-controlled parameter of the air conditioner and the user-controlled parameter of the target heater are set, the third target heating scheme includes the settings of the user-controlled parameter of the air conditioner and the user-controlled parameter of the target heater. If the first scenario mode of the vehicle is set by the user, the determination of the third target heating scheme is associated with the first scenario mode. Exemplarily, when the first scenario mode is the energy saving mode, the third target heating scheme can be a heating scheme with the minimum total power in multiple heating schemes satisfying a first comfort condition; when the first scenario mode is the camping mode or the break mode, the third target heating scheme can be a heating scheme with the minimum air volume of the air conditioner or the air volume of the air conditioner being less than an air volume threshold in multiple heating schemes satisfying a third comfort condition; when the first scenario mode is the defogging mode or the defrosting mode, the third target heating scheme makes the passenger compartment satisfy a fourth comfort condition, and in the third target heating scheme, the proportion of the air volume of the air conditioner acting on the glass of the vehicle is greater than the proportion of the air volume of the air conditioner acting on the occupant. When the desired temperature of the passenger compartment is also set by the user, the first comfort condition, the third comfort condition, and the fourth comfort condition are all related to the desired temperature of the passenger compartment, for example, can be a comfort value corresponding to the desired temperature of the passenger compartment.

[0257] It can be seen that the heating scheme is determined based on the setting information of the user, and the heating scheme fully considers the current needs and preferences of the user, thereby improving the user experience.

[0258] In some possible embodiments, the air conditioner and the target heater can also be controlled to heat the passenger compartment according to the setting information of the user and the ambient temperature information. In this case, not only the intention of the user is considered, but also the current temperature in the cabin can be known in combination with the ambient temperature information, so that the difference between the current temperature in the cabin and the expected temperature (for example, the expected temperature of the passenger compartment) can be known, and the heating scheme can be determined more accurately, so that the air conditioner and the target heater can be controlled to perform heating better.

[0259] In some possible embodiments, the air conditioner and the target heater can also be controlled to heat the passenger compartment according to the setting information of the user and the state information of the vehicle. In this case, when the first scenario mode of the vehicle in the setting information of the user is different from the second scenario mode of the vehicle in the state information of the vehicle, the first scenario mode of the vehicle is used as the reference. In this implementation, the setting information of the user and the state information of the vehicle are combined to determine a heating scheme, not only the intention of the user is considered, but also the current state of the vehicle is considered, so that the air conditioner and the target heater can be controlled to perform heating more accurately and more scientifically, and the user is friendly.

[0260] In some possible embodiments, when the reference information includes the member distribution information, the member distribution information is used to indicate the position area of the occupant in the passenger compartment, and the air conditioner and the target heater controlled to act on the position area where the occupant is located, so that the target area (that is, the position area where the occupant is located) is heated accurately, which is beneficial to improve the temperature rising rate of the target area and save the power consumption of the whole vehicle.

[0261] For example, the position area where the occupant is located is a first position area, and the air conditioner and the target heater acting on the first position area means that the air conditioner and the target heater are used to heat the first position area, and / or the air conditioner and the target heater are installed in the first position area or arranged near the first position area.

[0262] In one application scenario, the method shown in the embodiment of FIG. 2 can be applied to a control device in a vehicle.

[0263] In another application scenario, the method shown in the embodiment of FIG. 2 can also be applied to a network side device, in which case, the "obtaining reference information" in S201 means receiving the reference information from the vehicle, and the "controlling the air conditioner and the target heater to heat the passenger compartment of the vehicle according to the reference information" in S202 means: determining a target heating scheme according to the reference information; and sending a control instruction to the vehicle, the control instruction including the target heating scheme, and the control instruction instructing the air conditioner and the target heater to heat the passenger compartment according to the target heating scheme. This implementation is described below in the embodiment of FIG. 6, which is not described here again.

[0264] The embodiment of FIG. 2 can control the air conditioner to perform heating when the vehicle has a rapid heating demand, and can also control a target heater (for example, at least one of a contact heater and a radiation heater) other than the air conditioner to perform heating, so as to realize rapid heating of the passenger compartment, so that the occupant in the passenger compartment can quickly reach thermal comfort, and the ride comfort of the vehicle is improved. In addition, the heating scheme for controlling the air conditioner and the target heater to perform heating is determined based on the obtained reference information, and the reference information at least includes environmental temperature information and / or user setting information, and in addition can also include vehicle state information, member distribution information, etc. The optimal heating scheme determined in different scenarios can be different, so that more scientific and accurate heating is realized in different scenarios, which is not only beneficial to improve comfort, but also can realize the effects of saving energy consumption, optimizing NVH performance, ensuring fast charging rate, improving driving safety, etc. in the corresponding scenarios.

[0265] Referring to FIG. 6, FIG. 6 is a flowchart of another heating control method provided by the embodiment of the application. The method can be applied to the heating control system shown in FIG. 1B, for example, the heating control system includes a vehicle and a network side device, and the vehicle has the structure shown in FIG. 1A, that is, the vehicle is internally disposed with a control device, an air conditioner, a contact heater and a radiation heater.

[0266] The method shown in FIG. 6 includes but is not limited to the following steps S601-S604.

[0267] S601: The vehicle sends reference information to the network side device, and the reference information includes at least one of environmental temperature information and user setting information. Correspondingly, the network side device receives the reference information from the vehicle.

[0268] Here, the reference information is described in the corresponding description of the reference information in the embodiment S201 of FIG. 2, which is not repeated here.

[0269] Exemplarily, the vehicle can send the reference information to the network side device in a timely or periodic manner.

[0270] S602: The network side device determines a target heating scheme according to the reference information. For details, please refer to the description of the corresponding content in the foregoing embodiment S202 of FIG. 2. The target heating scheme can be the first target heating scheme, the second target heating scheme or the third target heating scheme in the embodiment of FIG. 2, and is not repeated here.

[0271] The target heating scheme includes the setting of the control parameter of the air conditioner and the control parameter of the target heater. The target heater includes at least one of the contact heater and the radiation heater.

[0272] S603: The network side device sends a control instruction to the vehicle, and the control instruction includes the target heating scheme.

[0273] The control instruction indicates the vehicle to control the air conditioner and the target heater to heat the passenger cabin according to the target heating scheme.

[0274] S604: In response to the control instruction, the vehicle controls the local air conditioner and the target heater to heat the passenger cabin according to the target heating scheme.

[0275] Exemplarily, the control device of the vehicle controls the air conditioner and the target heater to heat the passenger cabin according to the target heating scheme. Here, the control of the control device of the vehicle on the air conditioner and the target heater can be direct control or indirect control.

[0276] Exemplarily, the indirect control refers to: the control device of the vehicle sends a first control instruction to the controller of the air conditioner, so that the controller of the air conditioner controls the air conditioner to perform heating based on the first control instruction, and the first control instruction includes the control parameter of the air conditioner set in the target heating scheme; and the control device of the vehicle sends a second control instruction to the controller of the target heater, so that the controller of the target heater controls the target heater to perform heating based on the second control instruction, and the second control instruction includes the control parameter of the target heater set in the target heating scheme. It can be understood that when the target heater includes a contact heater and a radiation heater, the control device of the vehicle can send corresponding control instructions to the controllers of the contact heater and the radiation heater respectively.

[0277] In some schemes, after the vehicle obtains the target heating scheme locally, the vehicle can also inform the user of the target heating scheme. For example, the user is informed of the currently executed heating scheme through text display, voice broadcast and the like.
