Description

Technical Field

[0001] The present application relates to the field of smart cars, and more specifically, to a control method, a heating system and a vehicle. Background Art

[0002] Traditional vehicles can use the engine's waste heat to fully heat the passenger compartment during winter heating, but the heating rate is slow. New energy vehicles (hybrid / extended range pure electric mode, or pure electric models) do not have engine waste heat, so they need to use electric heating or air conditioning heat pumps to heat the air to heat the passenger compartment. This extra energy consumption greatly affects the winter energy consumption and endurance of new energy vehicles.

[0003] Therefore, how to reduce the power consumption of new energy vehicles has become an urgent problem to be solved. Summary of the invention

[0004] The present application provides a control method, a heating system and a vehicle, which help to reduce the power consumption of the vehicle, thereby helping to improve the vehicle's cruising range.

[0005] In a first aspect, a heating system is provided, which includes a first control unit, a first drive device and a first vehicle-mounted heating unit, one end of the first drive device is connected to a power supply device and the other end is connected to the first vehicle-mounted heating unit, wherein the first control unit is used to send a first instruction to the first drive device, the first instruction indicating a connection status between the power supply device and the first vehicle-mounted heating unit; the first drive device is used to disconnect the power supply device from the first vehicle-mounted heating unit when the connection status indicates disconnecting the power supply device from the first vehicle-mounted heating unit; or connect the power supply device to the first vehicle-mounted heating unit when the connection status indicates connecting the power supply device and the first vehicle-mounted heating unit.

[0006] Based on the above technical solution, the control unit can output an instruction to the drive device. When the instruction indicates that the power supply device and the vehicle heating unit are disconnected, the drive device can disconnect the power supply device and the vehicle heating unit. This can avoid the static power consumption generated by the vehicle heating unit when it is not working, which helps to save the power consumption of the vehicle, thereby helping to improve the vehicle's cruising range; at the same time, the large current of the power supply device will not pass through the control unit, which helps to avoid the temperature of the control unit rising rapidly when controlling the vehicle heating unit to work, resulting in an increase in the vehicle's energy consumption. There is no need to configure a controller in the vehicle heating unit, which helps to reduce the production cost of the vehicle heating unit.

[0007] The above driving device may also be referred to as a driving switch. The driving device may be used to connect the power supply device and the first vehicle-mounted heating unit, or to disconnect the power supply device and the first vehicle-mounted heating unit.

[0008] The above on-board heating unit may include a radiant heater and / or a contact heater.

[0009] In combination with the first aspect, in certain implementations of the first aspect, the first control unit is further used to send a second instruction to the first driving device, and the second instruction is used to indicate the output power of the power supply device to the first vehicle-mounted heating unit; the first driving device is further used to control the output power of the power supply device to the first vehicle-mounted heating unit according to the second instruction.

[0010] Based on the above technical solution, the control unit can also output instructions to the driving device, and the instructions can be used to control the output power to the on-board heating unit, which helps to improve the flexibility of the control unit in controlling the on-board heating unit.

[0011] In combination with the first aspect, in certain implementations of the first aspect, the first driving device includes a relay, and the first instruction includes a first level or a second level, wherein the first level indicates disconnection of the power supply device and the first vehicle heating unit, and the second level indicates connection of the power supply device and the first vehicle heating unit.

[0012] Exemplarily, the first level may be a low level, and the second level may be a high level.

[0013] Based on the above technical solution, the control unit outputs high and low levels to the relay, so that the relay can disconnect or connect the power supply device and the vehicle heating unit, which can shorten the response time of the vehicle heating unit; at the same time, there is no need to configure a controller in the vehicle heating unit, and there is no need to parse the signal from the first controller before controlling the operation of the vehicle heating unit. The relay can start working after connecting the power supply device and the vehicle heating unit.

[0014] In combination with the first aspect, in certain implementations of the first aspect, the first vehicle-mounted heating unit includes a temperature detection module, and the first vehicle-mounted heating unit is used to send data collected by the temperature detection module to the first control unit; the first control unit is used to send the first instruction to the first driving device based on the data.

[0015] Based on the above technical solution, the vehicle heating unit can improve the accuracy of the control unit's calculation of the cabin temperature by sending the data collected by the temperature detection module to the control unit, thereby avoiding the phenomenon that the temperature output by the temperature sensor is too high due to the close distance between the temperature sensor and the vehicle heating unit.

[0016] In combination with the first aspect, in certain implementations of the first aspect, the first control unit is further used to obtain temperature information and a status of the air conditioner, the temperature information including the temperature outside the vehicle and / or the temperature inside the vehicle; the first control unit is used to output the first instruction to the drive device based on the temperature information and the status of the air conditioner.

[0017] Based on the above technical solution, the control unit can output the first instruction to the drive device based on the temperature information and the state of the air conditioner, so that the linkage control of the air conditioner and the vehicle heating unit can be realized.

[0018] In some possible implementations, the first control unit is used to send the first instruction to the drive device when the temperature outside the vehicle is less than or equal to a first preset temperature. The first instruction is used to instruct the connection between the power supply device and the first vehicle heating unit.

[0019] In some possible implementations, the first control unit is also used to send an instruction to the air-conditioning controller when the temperature outside the vehicle is less than or equal to a first preset temperature. The instruction is used to instruct one or more of lowering the air outlet temperature and / or air outlet speed of the air conditioner, lowering the power of the air conditioner, and lowering the gear of the air conditioner.

[0020] Since the energy consumption of the air conditioner is higher than that of the vehicle heating unit, when the temperature outside the vehicle is less than or equal to the preset temperature, the vehicle heating unit can be automatically turned on and the energy consumption of the air conditioner can be reduced, which helps to increase the speed of temperature increase in the cabin and also helps to reduce the energy consumption required for heating, thereby helping to increase the vehicle's range.

[0021] In some possible implementations, the first control unit is further used to send an instruction to the first drive device when the temperature inside the vehicle is greater than or equal to the second preset temperature, the instruction being used to instruct the power supply device to reduce the output power of the first vehicle heating unit, or the instruction being used to instruct the power supply device to disconnect from the first vehicle heating unit. In this way, it is possible to avoid the power supply device always maintaining a high power output to the vehicle heating unit. When the temperature inside the vehicle meets the conditions, the power supply device can reduce the output power of the vehicle heating unit or turn off the vehicle heating unit, which helps save the energy consumption of the vehicle and thus helps to improve the vehicle's cruising range.

[0022] In combination with the first aspect, in certain implementations of the first aspect, the first vehicle-mounted heating unit is located in a first area within a vehicle cabin, and the first control unit is further used to obtain data collected by a pressure sensor on a seat in the first area; the first control unit is further used to send a first instruction to the first drive device when the data collected by the pressure sensor indicates that there is a user in the first area, and the first instruction instructs to connect the power supply device and the first vehicle-mounted heating unit.

[0023] Based on the above technical solution, when there is a user in the first area, the control unit can control the vehicle heating unit in the first area to work. In this way, it can avoid energy waste caused by turning on the vehicle heating unit when there is no user in other areas, which helps to achieve accurate control of the vehicle heating unit in the cabin.

[0024] In combination with the first aspect, in certain implementations of the first aspect, the first control unit is further used to obtain driving data of the vehicle; the first control unit is further used to send the first instruction to the first drive device based on the driving data of the vehicle.

[0025] Based on the above technical solution, the control unit can send a first instruction to the drive device based on the driving data of the vehicle. For example, when the vehicle needs to accelerate urgently, the control unit can instruct the drive device to disconnect the power supply device and the vehicle heating unit, so that more power can be allocated to the vehicle's drive motor, which helps to ensure the vehicle's acceleration performance, thereby helping to improve the user's driving safety.

[0053] The technical solutions in the embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0054] Figure 1 1 is a functional block diagram of a vehicle 100 provided in an embodiment of the present application. The vehicle 100 may include an onboard heating unit 120 and a computing platform 150, wherein the onboard heating unit 120 may include a contact heater and / or a radiation heater.

[0055] Some or all functions of the vehicle 100 may be controlled by the computing platform 150. The computing platform 150 may include one or more processors, such as processors 151 to 15n (n is a positive integer). The processor is a circuit with signal processing capability. In one implementation, the processor may be a circuit with instruction reading and execution capability, such as a central processing unit (CPU), a microprocessor, a graphics processing unit (GPU) (which can be understood as a microprocessor), or a digital signal processor (DSP). In another implementation, the processor may implement certain functions through the logical relationship of a hardware circuit, and the logical relationship of the hardware circuit is fixed or reconfigurable, such as a hardware circuit implemented by a processor such as an application-specific integrated circuit (ASIC) or a programmable logic device (PLD), such as a field programmable gate array (FPGA). In a reconfigurable hardware circuit, the process of the processor loading a configuration document to implement the hardware circuit configuration can be understood as the process of the processor loading instructions to implement the functions of some or all of the above units. In addition, the processor may also be a hardware circuit designed for artificial intelligence, which may be understood as an ASIC, such as a neural network processing unit (NPU), a tensor processing unit (TPU), a deep learning processing unit (DPU), etc. In addition, the computing platform 150 may also include a memory, the memory is used to store instructions, and some or all of the processors 151 to 15n may call the instructions in the memory to implement corresponding functions.

[0056] Optionally, the vehicle 100 may also include a display device. Display devices are mainly divided into two categories, the first category is the vehicle-mounted display screen; the second category is a projection display screen, such as a head up display (HUD). The vehicle-mounted display screen is a physical display screen and an important part of the vehicle infotainment system. Multiple display screens can be set in the cockpit, such as a digital instrument display screen, a central control screen, a display screen in front of the passenger in the co-pilot seat (also called the front passenger), a display screen in front of the left rear passenger, and a display screen in front of the right rear passenger. Even the window can be used as a display screen for display. Head-up display, also known as a head-up display system. It is mainly used to display driving information such as speed and navigation on a display device in front of the driver (such as a windshield). To reduce the driver's line of sight diversion time, avoid pupil changes caused by the driver's line of sight diversion, and improve driving safety and comfort. HUD includes, for example, a combiner-HUD (C-HUD) system, a windshield-HUD (W-HUD) system, and an augmented reality HUD (AR-HUD) system. It should be understood that other types of HUD systems may also appear as technology evolves, and this application does not limit this.

[0057] There are three basic ways of heat transfer in a vehicle: convection, radiation, and conduction.

[0058] Air conditioning in vehicles is mainly a heat convection mechanism, which uses air conditioning to cool and heat the air, heats the cabin environment through air conditioning, and provides users with a warm environment and comfortable body feeling through convection between hot air and the human body. However, the air conditioning system has experience problems such as blower / compressor noise, uncomfortable blowing feeling, low heating efficiency and high energy consumption.

[0059] Contact heaters are heat conduction mechanisms. For example, contact heaters are seat heaters. They heat the seat surface and transfer heat to the human body in a contact manner. This method is highly efficient, but it can only heat the area where the human body is in contact with the seat, and cannot provide heating for the head, feet, and torso of the human body.

[0060] Radiant heating is a thermal radiation mechanism that can directly radiate energy to the human body through the heating plate and heat it efficiently.

[0061] For example, Figure 2The schematic diagram of the air conditioner, contact heater, and radiation heater in the vehicle cabin provided by the embodiment of the present application is shown. The vehicle may include the above three heating devices or have two of them. There may be multiple heating devices of each type, for example, contact heater 1 is used to heat the back of the seat, contact heater 2 is used to heat the buttocks of the seat, radiation heater 1 is used to heat the head area, contact heater 3, radiation heater 2 and radiation heater 3 are used to heat the leg area, etc.

[0062] For example, Figure 3 FIG. 1 is a schematic diagram of a radiant heater in a vehicle cabin provided by an embodiment of the present application. Figure 3 As shown, the main driving area of ​​the vehicle includes a radiant heater 4, a radiant heater 5, a radiant heater 6 and a radiant heater 7, wherein the radiant heater 4 is located on the roof of the vehicle, the radiant heater 5 is located on the door handle of the main driving area, the radiant heater 6 is located on the seat of the main driving area, and the radiant heater 7 is located on the steering wheel.

[0063] Figure 4 FIG. 4 shows a schematic block diagram of a heating system 400 provided in an embodiment of the present application. Figure 4 As shown, the heating system 400 includes a first control unit 410, a first driving device 420 and a first vehicle-mounted heating unit 430, one end of the first driving device 420 is connected to a power supply device 440 and the other end is connected to the first vehicle-mounted heating unit 430, wherein the first control unit 410 is used to send a first instruction to the first driving device 420, and the first instruction indicates the connection status of the power supply device 440 and the first vehicle-mounted heating unit 430; the first driving device 420 is used to disconnect the power supply device 440 from the first vehicle-mounted heating unit 430 when the connection status indicates disconnecting the power supply device 440 and the first vehicle-mounted heating unit 430; or, when the connection status indicates connecting the power supply device 440 and the first vehicle-mounted heating unit 430, connect the power supply device 440 and the first vehicle-mounted heating unit 430.

[0064] The power supply device 440 may be located in the heating system 400 or outside the heating system 400 .

[0065] Exemplarily, the power supply device 440 may be a KL30 power supply line, or the power supply device 440 may be a power battery and a direct current converter (DCDC), which converts the high voltage of the power battery into a low voltage to supply power to the on-board heating unit in the low-voltage power grid.

[0066] Optionally, the first control unit 410 may be an electronic control unit (ECU).

[0067] Optionally, the first control unit 410 may be a vehicle integration unit (VIU). Exemplarily, the VIU may have one or more of the following functions:

[0068] (1) Electronic control function

[0069] VIU can be used to implement the electronic control functions provided by the ECU inside some or all of the automotive components, such as the control function required by a certain automotive component or the data processing function required by a certain automotive component.

[0070] (2) Same functions as gateway

[0071] The VIU may have some or all of the same functions as the gateway, such as a protocol conversion function, a protocol encapsulation and forwarding function, and a data format conversion function.

[0072] (3) Data processing function across automobile parts

[0073] VIU can process and calculate the data obtained from the actuators of multiple automotive components.

[0074] The first driving device 420 may be a device independent of the first control unit 410 and the first vehicle heating unit 430 , or the first driving device may be integrated into the first control unit 410 .

[0075] Optionally, the first control unit 410 is also used to send a second instruction to the first driving device 420, and the second instruction is used to instruct the power supply device 440 to output power to the first vehicle-mounted heating unit 430; the first driving device 420 is also used to control the output power of the power supply device 440 to the first vehicle-mounted heating unit 430 according to the second instruction.

[0076] Exemplarily, the output power of the power supply device may be a fixed value (e.g., 500 W). The first control unit 410 may send the second instruction to the first driving device 420 based on one or more of the temperature information, the number of passengers in the vehicle, the position of passengers in the vehicle, the driving data of the vehicle, and the state of the air conditioner.

[0077] For example, when the outside temperature (or the inside temperature) is less than or equal to -15°C, the first control unit 410 can send an instruction to the first driving device 420, which instructs the first driving device 420 to control the power supply device to output 500W and control the first vehicle heating unit 430 to operate.

[0078] For another example, after a period of time, when the temperature inside the vehicle is greater than or equal to 10°C, the first control unit 410 may send an instruction to the first driving device 420, instructing the first driving device 420 to control the power supply device to output 300W of power and control the first vehicle heating unit 430 to operate.

[0079] For another example, after a period of time, when the temperature inside the vehicle is greater than or equal to 15°C, the first control unit 410 may send an instruction to the first driving device 420, instructing the first driving device 420 to control the power supply device to output 200W of power and control the first vehicle heating unit 430 to operate.

[0080] Optionally, the first driving device 420 includes a relay, and the first instruction includes a first level or a second level, wherein the first level indicates disconnecting the connection between the power supply device 440 and the first vehicle heating unit 430, and the second level indicates connecting the power supply device 420 and the first vehicle heating unit 430.

[0081] For example, Figure 5 A schematic block diagram of a heating system 500 provided in an embodiment of the present application is shown. The heating system 500 includes a VIU 510, a relay 520, a relay 521, a heating node 530 and a heating node 531. Among them, the power pin of the heating node 530 is connected to one end of the relay 520, and the other end of the relay 520 is connected to KL30, and the power pin of the heating node 531 is connected to one end of the relay 521, and the other end of the relay 521 is connected to KL30. The VIU 510 includes a system-on-a-chip (SoC) and a driver module (for example, a low side driver (LSD)). The VIU 510 control pins are connected to the relay 520 and the relay 521 to control enable, so as to achieve the purpose of the VIU 510 controlling the heating node 530 and the heating node 531 to work.

[0082] Above Figure 5 In the heating system 500 shown, KL30 can power the SoC in the VIU 510, and since the current required by the SoC is relatively small, no large current will flow through the VIU 510. Since the large current of KL30 will not flow through the VIU 510, the heat dissipation performance of the VIU 510 is not required to be high, which helps to reduce the heat dissipation cost of the VIU.

[0083] The first control unit 410 may be the VIU 510 , or the first control unit 410 may be a SoC in the VIU 510 .

[0084] The first driving device 420 may be the relay 520 , and the first vehicle-mounted heating unit 430 may be the heating node 530 ; or, the first driving device 420 may be the relay 521 , and the first vehicle-mounted heating unit 430 may be the heating node 531 .

[0085] The above power supply device 440 may be the above-mentioned KL30.

[0086] The above is explained by taking each heating node as an example in which each heating node is connected to its corresponding relay, and the embodiments of the present application are not limited thereto. For example, one end of the heating node 530 and the heating node 531 can be respectively connected to the same relay, and the relay can be used to simultaneously connect or disconnect KL30 and multiple heating nodes. In this way, the connection status of KL30 and multiple heating nodes can be controlled by the same relay, which helps to further reduce the production cost of the heating system.

[0087] Optionally, the first vehicle-mounted heating unit is located in a first area within a vehicle cabin, and the first control unit is also used to obtain data collected by a pressure sensor on a seat in the first area; the first control unit is also used to send a first instruction to the first drive device when the data collected by the pressure sensor indicates that there is a user in the first area, and the first instruction instructs to connect the power supply device and the first vehicle-mounted heating unit.

[0088] Exemplarily, the heating node 530 is a radiant heater in the main driving area (for example, a radiant heater on the door handle in the main driving area, a radiant heater on the ceiling in the main driving area, a radiant heater on the steering wheel in the main driving area, etc.). The SoC can obtain data collected by the pressure sensor on the seat in the main driving area. When the data indicates that there is a user in the main driving area and the outside temperature is less than or equal to -15°C, the SoC can send an instruction to the drive module, which is used to indicate the connection between KL30 and the heating node 530. The drive module can output a high level to the relay 520 according to the instruction, so that the relay 520 connects KL30 and the heating node 530. KL30 can supply power to the heating node 530.

[0089] Exemplarily, the heating node 531 is a radiant heater in the second row left area (for example, a radiant heater on the door handle in the second row left area, a radiant heater on the ceiling in the second row left area, etc.). The SoC can obtain data collected by the pressure sensor on the seat in the second row left area. When the data indicates that there is no user in the second row left area, the SoC can send an instruction to the drive module, which is used to instruct to disconnect KL30 and the heating node 531. The drive module can output a low level to the relay 521 according to the instruction, so that the relay 521 disconnects KL30 and the heating node 531.

[0090] The above VIU 510 may be located in the left area of ​​the vehicle.

[0091] above Figure 5 The example in which the vehicle includes two heating nodes and two relays is used for illustration, and the embodiments of the present application are not limited thereto. The vehicle may also include more or fewer heating nodes and relays.

[0092] Optionally, the heating system 400 also includes a second control unit, a second driving device and a second vehicle-mounted heating unit, one end of the second driving device is connected to the power supply device and the other end is connected to the second vehicle-mounted heating unit, the first control unit and the second control unit are connected, wherein the first control unit and the first vehicle-mounted heating unit are located in a first area of ​​the vehicle, and the second control unit and the second vehicle-mounted heating unit are located in a second area of ​​the vehicle.

[0093] For example, Figure 6 A schematic block diagram of a heating system 500 provided in an embodiment of the present application is shown. The heating system 500 also includes a VIU 511, a relay 522, a relay 523, a heating node 532, and a heating node 533. Among them, the power pin of the heating node 532 is connected to one end of the relay 522, and the other end of the relay 522 is connected to KL30, and the power pin of the heating node 533 is connected to one end of the relay 523, and the other end of the relay 523 is connected to KL30. The VIU 511 includes a SoC and a drive module (e.g., LSD). The VIU 511 control pin is connected to the relay 522 and the relay 523 to control enable, so as to achieve the purpose of the VIU 511 controlling the heating node 532 and the heating node 533 to work.

[0094] The second control unit may be the VIU 511. The VIU 511 may be located in the right area of ​​the vehicle, and the heating nodes on the right side of the vehicle may be connected to the VIU 511.

[0095] The second driving device may be the relay 522 , and the second vehicle-mounted heating unit may be the heating node 532 ; or, the second driving device may be the relay 523 , and the second vehicle-mounted heating unit may be the heating node 533 .

[0096] The above VIU510 and VIU511 can be connected by wire or wirelessly. For example, VIU510 and VIU511 can be connected by Ethernet (ETH). When VIU510 fails, VIU511 can output a level to relay 520 or 521, thereby controlling heating node 530 and heating node 531.

[0097] The above description is based on the example of the connection between VIU510 and VIU511 via ETH, but the present application is not limited thereto. For example, VIU510 and VIU511 may also be connected via a controller area network (CAN).

[0098] Optionally, the first vehicle-mounted heating unit includes a temperature detection module, and the first vehicle-mounted heating unit is used to send data collected by the temperature detection module to the first control unit; the first control unit is used to send the first instruction to the first driving device according to the data.

[0099] For example, Figure 5 and Figure 6 As shown, each heating node may include a negative temperature coefficient (NTC) temperature detection module. The NTC temperature detection module can collect the temperature near the node in real time and convert it into a voltage signal, and then send the voltage signal to the analog to digital converter (ADC) inside the VIU. The ADC performs analog to digital conversion to obtain the corresponding temperature information and send it to the SoC inside the VIU. The SoC can determine the ambient temperature in the cabin by combining the data collected by the temperature sensor and the temperature information converted by the ADC. In this way, the accuracy of the SoC's calculation of the temperature in the cabin can be improved, and the phenomenon of falsely high temperature output by the temperature sensor due to the close distance between the temperature sensor and the heating node can be avoided.

[0100] The above description is based on the example that the ADC and the SoC are two independent components in the VIU, and the embodiments of the present application are not limited thereto. For example, the ADC may also be integrated in the SoC.

[0101] The above is explained by taking the heating node including the NTC temperature detection module (or the NTC temperature detection module is integrated in the heating node) as an example, and the embodiments of the present application are not limited to this. For example, the NTC temperature detection module may not be integrated in the heating node, but may be located near the heating node. For another example, the function of the NTC temperature detection module may also be implemented by a positive temperature coefficient (PTC) temperature detection unit.

[0102] Exemplarily, the heating node 530 is located in the main driving area, and the SoC can determine the temperature of the main driving area by combining data collected by the temperature sensor in the main driving area and data collected by the NTC temperature detection module in the heating node 530 .

[0103] Optionally, the first control unit 410 is also used to obtain temperature information and the status of the air conditioner, the temperature information including the temperature outside the vehicle and / or the temperature inside the vehicle; the first control unit 410 is used to output the first instruction to the first drive device according to the temperature information and the status of the air conditioner.

[0104] Exemplarily, the VIU 510 and VIU 511 may be connected to an air conditioner controller. The air conditioner controller may send air conditioner status information to the VIU 510 and VIU 511, such as whether the air conditioner is turned on, the target temperature set by the user, the air outlet temperature of the air conditioner, the air outlet speed, the power, the gear, etc. The VIU 510 and VIU 511 may control the heating node in combination with the air conditioner status information.

[0105] Exemplarily, the heating node 530 is a radiant heater in the main driving area (for example, a radiant heater on the door handle in the main driving area, a radiant heater on the ceiling in the main driving area, a radiant heater on the steering wheel in the main driving area, etc.). The SoC can obtain the input of the target temperature (for example, 25°) of the air conditioner set by the user from the air conditioning controller and send an instruction to the drive module when the outside temperature is less than or equal to -15°C, which is used to indicate the connection between KL30 and the heating node 530. The drive module can output a high level to the relay 520 according to the instruction, so that the relay 520 connects KL30 and the heating node 530. KL30 can supply power to the heating node 530.

[0106] Exemplarily, when the SoC obtains the input of the target temperature (e.g., 28°) set by the user for the air conditioner and the outside temperature is less than or equal to -15°C, it can send an instruction to the driving module, which is used to instruct to disconnect the connection between KL30 and the heating node 530. According to the instruction, the driving module can output a low level to the relay 520, so that the relay 520 disconnects the connection between KL30 and the heating node 530. KL30 can stop supplying power to the heating node 520.

[0107] Exemplarily, the SoC can send an instruction to the driving module when obtaining the input of the target temperature (e.g., 28°) set by the user for the air conditioner and the outside temperature is less than or equal to -15°C, and the instruction is used to instruct to disconnect KL30 and the heating node 530, and the target temperature and the outside temperature correspond to the first air outlet temperature and / or the first air outlet speed of the air conditioner. The driving module can output a high level to the relay 520 according to the instruction, so that the relay 520 connects KL30 and the heating node 530. KL30 can supply power to the heating node 530. At the same time, the SoC can output an instruction to the air conditioner controller, which is used to instruct the air conditioner controller to lower the air outlet temperature and / or the air outlet speed. Thereby, the air conditioner controller can control the air outlet temperature of the air conditioner to be the second air outlet temperature, and / or the air outlet speed to be the second air outlet speed, and the second air outlet temperature is less than the first air outlet temperature, and the second air outlet speed is less than the first air outlet speed. In this way, when the vehicle is cold-started, the control unit can control the air outlet speed and / or air outlet temperature of the air conditioner to decrease, and automatically start the on-board heating unit, which can quickly increase the temperature in the cabin and help reduce the power consumption caused by heating, thereby helping to improve the vehicle's cruising range.

[0108] Optionally, the first control unit 410 is further used to obtain driving data of the vehicle; the first control unit 410 is further used to send the first instruction to the first driving device according to the driving data of the vehicle.

[0109] Exemplarily, the VIU510 and VIU520 can also be connected to a vehicle domain controller (VDC). The SoC in the VIU can obtain the vehicle's driving data from the VDC, and the driving data may include the vehicle's speed, acceleration, accelerator pedal opening, etc. For example, when the accelerator pedal opening change rate is greater than or equal to a preset value, VIU510 can output a low level to relay 520 and relay 521 respectively through a drive module, and VIU511 can output a low level to relay 522 and relay 523 respectively through a drive module, thereby disconnecting KL30 and the heating nodes 530-533. At this time, the vehicle can output more power to the drive motor to ensure the acceleration performance of the vehicle, thereby helping to improve the user's driving experience.

[0110] above Figure 5 and Figure 6 The driving device is described in the example of a relay, but the embodiments of the present application are not limited to this.

[0111] For example, the driving device may also be an insulated gate bipolar transistor (IGBT) switch or a metal-oxide-semiconductor field-effect transistor (MOS). For example, the MOS may be a silicon carbide MOS or a gallium nitride MOS. For example, the G pole (gate) of the MOS may be connected to the driving module in the VIU, the D pole (drain) may be connected to the KL30, and the S pole (source) may be connected to the heating node.

[0112] For another example, the driving device may also be an H-bridge driving circuit.

The heating system 700 includes VIU710, VIU711 and heating nodes 720-723. Among them, VIU710 includes SoC1 and H-bridge drive circuit 1, and VIU711 includes SoC1 and H-bridge drive circuit 1. The power pin of heating node 720 is connected to the power pin of H-bridge drive circuit 1, the power pin of heating node 721 is connected to the power pin of H-bridge drive circuit 1, the power pin of heating node 722 is connected to the power pin of H-bridge drive circuit 2, and the power pin of heating node 723 is connected to the power pin of H-bridge drive circuit 2. H-bridge drive circuit 1 and H-bridge drive circuit 2 respectively include current detection units, which can detect the output current (or output power) of the power supply device to the heating node in real time. KL30 can be connected to VIU710 and VIU711. In addition to controlling the connection or disconnection between the power supply device and the heating node, the H-bridge driving circuit 1 and the H-bridge driving circuit 2 can also control the output power of the power supply device to the heating node.

[0114] Exemplarily, heating node 720 is a radiation heater for the main driver's area (for example, a radiation heater on the door handle of the main driver's area, a radiation heater on the ceiling of the main driver's area, a radiation heater on the steering wheel of the main driver's area, etc.), and heating node 721 is a radiation heater for the co-driver's area (for example, a radiation heater on the door handle of the co-driver's area, a radiation heater on the ceiling of the co-driver's area, etc.). SoC1 can obtain data collected by pressure sensors on the seats in the main driver's area and the co-driver's area. When the data indicates that there is a user in the main driver's area and no one in the co-driver's area, SoC1 can send an instruction to the H-bridge drive circuit 1, which is used to instruct to supply power to the heating node 720 and stop supplying power to the heating node 721. According to the instruction, the H-bridge drive circuit 1 can connect KL30 and the heating node 720 and disconnect KL30 and the heating node 721. Or,

[0115] SoC1 can send an instruction to the H-bridge driver circuit 1, the instruction is used to indicate that the output power to the heating node 720 is 500W and the output power to the heating node 721 is 100W. According to the instruction, the H-bridge driver circuit 1 can connect KL30 and the heating node 720 and connect KL30 and the heating node 721. At the same time, the H-bridge driver circuit can adjust the output power of KL30 to the heating node 720 and the heating node 721, so that the output power to the heating node 720 is 500W, and the output power to the heating node 721 is 100W.

[0116] above Figure 7 In the above description, the H-bridge driving circuit and the SoC are two independent components in the VIU, but the embodiments of the present application are not limited thereto. For example, the H-bridge driving circuit can also be integrated in the SoC.

[0117] For example, Figure 8 A schematic block diagram of a heating system 800 provided in an embodiment of the present application is shown. The heating system 800 includes VIU810, VIU811 and heating nodes 820-823. The heating nodes 820-823 include an ECU, a local interconnect network (LIN) interface and an NTC temperature detection module. The ECU can be responsible for power drive, temperature recovery, current recovery, voltage recovery, and underlying control algorithms (temperature adjustment strategy, heating energy density control strategy, etc.). VIU810 and VIU811 include SoC and LIN interfaces. Each heating node can be connected to KL30 respectively.

[0118] Exemplarily, SoC1 can send a command to the corresponding heating node 820 through the LIN interface, and the command is used to instruct the heating node 820 to work. After the LIN interface of the heating node 820 receives the command, it can forward the command to the ECU of the heating node 820. Thus, the ECU can control the heating node 820 to work.
