[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0026] In a first aspect, embodiments of the present invention provide a functional control method for a thermal management controller.

[0027] In one embodiment, reference is made to Figure 1 , Figure 1 This is a flowchart illustrating the first embodiment of the functional control method for the thermal management controller of the present invention. Figure 1 As shown, the functional control methods of the thermal management controller include:

[0028] Step S10: Detect environmental information in the passenger cabin;

[0029] In this embodiment, the environmental information of the passenger cabin includes temperature, humidity, frost, fog, and fine particulate matter concentration. The temperature, humidity, frost, fog, and fine particulate matter concentration of the passenger cabin are detected and acquired by the thermal management controller so as to determine the needs of the passenger cabin based on the environmental information of the passenger cabin.

[0030] Optionally, in one embodiment, the environmental information includes: temperature, humidity, frost, fog, and fine particulate matter concentration.

[0031] In this embodiment, temperature, humidity, frost, fog, and fine particulate matter concentration are all factors affecting passenger experience in the passenger cabin. Temperature detection determines the current temperature of the passenger cabin. Humidity detection determines whether the passenger cabin is dry or humid. Frost and fog detection determines whether the defrosting and defogging functions need to be activated, enabling automatic activation of these functions. Fine particulate matter concentration detection determines whether the air purification function needs to be activated, ensuring passengers are in a good air quality environment. It should be noted that the environmental information in this invention may also include other factors affecting passenger experience, which are not limited here.

[0032] Step S20: Determine the passenger cabin requirements based on the environmental information;

[0033] In this embodiment, environmental information includes: temperature, humidity, frost, fog, and fine particulate matter concentration. Temperature detection determines whether the passenger cabin requires heating or cooling; humidity detection determines whether humidification or dehumidification is needed; frost and fog detection determines whether defrosting and defogging functions need to be activated; and fine particulate matter concentration detection determines whether air purification functions need to be activated.

[0034] Optionally, in one embodiment, step S20 includes:

[0035] When the temperature in the passenger cabin exceeds the first temperature threshold, the passenger cabin's demand is determined to be cooling demand.

[0036] When the temperature in the passenger cabin is lower than the second temperature threshold, the passenger cabin demand is determined to be a heating demand, where the first temperature threshold is greater than the second temperature threshold.

[0037] When the humidity in the passenger cabin exceeds the first humidity threshold, the passenger cabin's demand is determined to be a dehumidification demand.

[0038] When the humidity in the passenger cabin is less than the second humidity threshold, the passenger cabin's demand is determined to be a humidification demand, where the first humidity threshold is greater than the second humidity threshold.

[0039] When there is frost and / or fog on the windshield or left and right rearview mirrors of the passenger compartment, the passenger compartment’s demand is determined to be a defrosting and defogging demand.

[0040] When the concentration of fine particulate matter in the passenger cabin exceeds a preset value, the passenger cabin's requirement is determined to be an air purification requirement.

[0041] In this embodiment, the first temperature threshold can be 27°C. When the temperature of the passenger cabin is detected to be greater than 27°C, it indicates that the temperature of the passenger cabin is high, and the passenger cabin's demand is determined to be a cooling demand.

[0042] The second temperature threshold can be 10°C. When the temperature of the passenger cabin is detected to be less than 10°C, it indicates that the temperature of the passenger cabin is low, and the passenger cabin's demand is determined to be heating demand.

[0043] The first humidity threshold can be 65%. When the humidity in the passenger cabin is detected to be greater than 65%, it indicates that the current passenger cabin is relatively humid, and the passenger cabin's demand is determined to be dehumidification.

[0044] The first humidity threshold can be 40%. When the humidity in the passenger cabin is detected to be less than 40%, it indicates that the current passenger cabin is relatively dry, and the passenger cabin is determined to require humidification.

[0045] When there is frost and / or fog on the windshield or side mirrors of the passenger compartment, the passenger compartment's requirement is determined to be a defrosting and defogging requirement in order to ensure driving safety.

[0046] The preset value can be 75 μg / m 3 When the concentration of fine particulate matter in the passenger cabin is detected to be greater than 75 μg / m³ 3 If the current air quality is polluted, then the passenger cabin's requirement is determined to be air purification. It should be noted that the parameters in this embodiment are for reference only; other specific values ​​are not limited here.

[0047] Step S30: Execute the control strategy corresponding to the required parameters through the thermal management controller.

[0048] In this embodiment, refer to Figure 2 , Figure 2 This is a hardware architecture diagram of the thermal management controller of the present invention. Figure 2 As shown, the thermal management controller uses the S32K144 series MCU main chip with a maximum main frequency of 112MHz. It supports 2 CAN FD channels plus 1 standard CAN channel, 1M FLASH, 128K RAM, 2 LIN communication channels, 3 SPI communication channels, 48 ​​ADC channels, and 48 PWM channels.

[0049] The main MCU in the thermal management controller collects data from various sensors via an AD acquisition interface to input signals. This data includes: interior temperature and ambient temperature from temperature and pressure sensors; data from refrigerant temperature and pressure sensors; data from the left and right sun sensors; and evaporator temperature. Feedback data from servo motors includes: data from the left and right heating / cooling motors; data from the mode motor; and data from the internal / external circulation motor. The controller also collects negative ion signals from the negative ion detection module; heater pump signals from the heater pump detection module; blower signals from the voltage acquisition module; AQS signals from the AQ detection module; and PM2.5 concentration from the fine particulate matter (PM2.5) concentration acquisition module. Voltage and power status are collected via power lines KL30 and KL15. The power module uses the S1142D50H chip.

[0050] The blower circuit in the thermal management controller uses the LM2904 chip, and the blower relay driver uses the NCV8402, which has overvoltage, overcurrent, and overheat protection, and a rated drive current of 2A. The control frequency is 100Hz. The blower feedback circuit is closed-loop, enabling automatic compensation and adjustment of the control terminal voltage based on the blower terminal voltage when the vehicle voltage fluctuates, providing strong anti-interference capability. The CAN drive circuit in the thermal management controller uses the T1J1043 chip to control components such as the WPTC, compressor, PM2.5 sensor, AQS sensor, and negative ion generator. The LIN drive circuit in the thermal management controller uses the T1J1021 chip to control the water valve and electronic expansion valve components. The LIN communication circuit uses the TJA1021, supporting remote and local wake-up through the SCL1 output circuit. The CAN communication circuit uses the TJA1043, enabling remote wake-up. The negative ion drive circuit has a sampling accuracy of up to 10 bits. The pressure / temperature sensor and servo motor are powered by a 5V drive power supply. In the thermal management controller, the main MCU controls the blower, electric fan, and water pump via PWM. The main MCU also controls various mode motors (internal / external circulation motor, cooling / heating motor, and mode motor) via SPI. Finally, the main MCU controls the negative ion enable and solenoid valve drive via the I / O bus to output signals.

[0051] If the passenger cabin's demand is determined to be cooling, the thermal management controller executes the corresponding control strategy. If the passenger cabin's demand is determined to be heating, the thermal management controller executes the corresponding control strategy. If the passenger cabin's demand is dehumidification, the thermal management controller executes the corresponding control strategy. If the passenger cabin's demand is humidification, the thermal management controller executes the corresponding control strategy. If the passenger cabin's demand is defrosting / defogging, the thermal management controller executes the corresponding control strategy. If the passenger cabin's demand is air purification, the thermal management controller executes the corresponding control strategy. In this way, various passenger needs can be met without the need for numerous controllers, significantly reducing the vehicle's cost.

[0052] It should be noted that when multiple needs are identified in the passenger cabin, the control strategy corresponding to each need must be executed. For example, if the passenger cabin needs are identified as heating, defrosting and defogging, and air purification, then the control strategies corresponding to the heating, defrosting and defogging, and air purification needs will be executed.

[0053] In this embodiment, the needs of the passenger cabin are determined by detecting the environmental information of the passenger cabin, and then the control strategy corresponding to the needs is executed by the thermal management controller. In this way, passenger comfort can be met without configuring a large number of controllers, which greatly reduces the development cost of comfort-related functions of the car and solves the technical problems of numerous in-vehicle controllers and high car costs in related technologies.

[0054] Optionally, in one embodiment, reference is made to Figure 3 , Figure 3 For the present invention Figure 1 A detailed flowchart of step S30. (See attached diagram.) Figure 3 As shown, step S30 includes:

[0055] Step S301: When the passenger cabin requires cooling, the thermal management controller starts the heating and cooling damper motor, the internal and external circulation motor, the compressor, and the blower.

[0056] Step S302: When the passenger cabin requires heating, adjust the WPTC power and control the start of the warm air pump, shut-off valve, hot and cold air damper motor and internal and external circulation motor.

[0057] Step S303: When the passenger cabin requires dehumidification, the air conditioner is activated to blow air and the windows are opened via the thermal management controller.

[0058] Step S304: When the passenger cabin requires humidification, the air conditioning is switched to automatic mode and the windows are closed via the thermal management controller.

[0059] Step S305: When the passenger cabin requires defrosting and defogging, the compressor, heating and cooling dampers, and blower are controlled by the thermal management controller to enter the defrosting and defogging mode.

[0060] Step S306: When the passenger cabin requires air purification, the negative ion generator is activated via the thermal management controller to enable the purification function.

[0061] In this embodiment, when the passenger cabin requires cooling, the thermal management controller is activated. The thermal management controller controls the start of the heating / cooling damper motor, the internal / external circulation motor, the compressor, and the blower. It controls the compressor speed based on the difference between the target temperature and the current temperature of the evaporator, and adjusts the blower speed based on the evaporator temperature and the current evaporator mode. Specifically, if the difference between the target temperature and the current temperature of the evaporator is greater than or equal to a first preset temperature difference (e.g., 1°C), the anti-frost protection timer is cleared, and the compressor speed is output. If the difference between the target temperature and the current temperature of the evaporator is less than the preset temperature difference, it checks whether the compressor operating speed is less than the preset speed. If the compressor operating speed is less than the preset speed, it controls the compressor to run at the preset speed and activates the anti-frost protection timer. If the timer is less than a first preset timeout (e.g., 60 seconds), the compressor speed is output. If the timer is greater than the first preset timeout but less than a second preset timeout (e.g., 90 seconds), the compressor is controlled to run at the preset speed. If the timer is greater than the second preset timeout and the evaporator temperature is less than a second preset temperature (e.g., -1°C), the thermal management controller controls the compressor to shut down.

[0062] When the passenger cabin requires heating, the thermal management controller is activated. The thermal management controller adjusts the power of the WPTC (high-temperature heater) based on the temperature difference between the target temperature of the WPTC and the outlet temperature of the WPTC, and controls the start of the warm air pump, shut-off valve, hot and cold air damper motor, and internal and external circulation motor, thereby achieving rapid heating of the passenger cabin.

[0063] Humidity in the passenger cabin is a crucial factor affecting human comfort. Excessive humidity creates high water vapor pressure around the skin, inhibiting sweat production and preventing heat dissipation, leading to discomfort. Conversely, low humidity causes dry skin, also causing discomfort. Therefore, when dehumidification is needed in the passenger cabin, the thermal management controller activates the air conditioning in fan mode and opens the windows to reduce water vapor pressure around the skin. When humidification is needed, the thermal management controller switches the air conditioning to automatic mode and closes the windows to increase water vapor pressure around the skin, ensuring the humidity in the passenger cabin remains within a normal range.

[0064] In one embodiment, the air conditioner, in automatic mode, needs to avoid hot air blowing onto the face. If the current evaporator temperature is greater than 28°C and the ambient temperature is greater than 22°C, the thermal management controller controls the servo motor to switch to glass-blowing mode to prevent hot air from blowing onto the face. If the current evaporator temperature is less than 22°C or the ambient temperature is less than 0°C, the thermal management controller controls the servo motor to exit glass-blowing mode and return to automatic control mode. The anti-cold-air blowing mode is executed only once each time the air conditioner enters automatic mode. If it has already been executed, and certain operating conditions trigger the anti-cold-air blowing mode, this function will not be executed again. In automatic mode, the air conditioner needs to avoid cold air blowing onto the feet; this function is not required in manual mode. If the current outlet air temperature is less than 30°C and the ambient temperature is less than 5°C, the anti-cold-air blowing mode is entered, and the blowing mode is adjusted to glass-blowing mode. During the anti-cold-air blowing mode, the air cannot continuously blow onto the glass. After 180 seconds of blowing onto the glass, if the current outlet air temperature is still less than 35°C, the anti-cold-air blowing mode is exited, and the air conditioner returns to the current automatic control state.

[0065] In one embodiment, when the air conditioning is first turned on in summer, the thermal management controller controls the damper motor to avoid pointing towards the faces of passengers in the passenger compartment, preventing the first blast of hot or cold air from blowing on their faces and thus preventing dust on the damper from being inhaled by the driver or passengers, affecting their health or causing discomfort. When the air conditioning is first turned on in winter, the thermal management controller controls the damper motor to avoid pointing towards the feet, preventing the first blast of hot or cold air from blowing on the feet and causing discomfort, thereby affecting driving safety.

[0066] When the passenger cabin requires defrosting and defogging, the thermal management controller controls the compressor, hot and cold air dampers, and blower to enter the defrosting and defogging mode, ensuring that the mixed air from the air outlet is promptly blown onto the windshield or left and right rearview mirrors of the passenger cabin, thereby eliminating frost and / or fog in a short time.

[0067] Because fine particulate matter can be quite harmful to human health, especially for sensitive individuals, the negative ion generator is activated via the thermal management controller when air purification is required in the passenger cabin. The negative ion generator selection function allows users to set its on / off status. The controller displays the ion generator's graphic on the vehicle information screen to provide passengers with feedback on its operating status. In the system where the thermal management controller controls various loads, the negative ion generator is located within the air conditioning unit and controlled by the thermal management controller. When the negative ion generator is operating, the air conditioning system blows negative ions into the passenger cabin.

[0068] When the air purification button on the control panel receives a "negative ion status" message, the thermal management controller keeps the negative ion generator running. When the negative ion generator is turned on, the thermal management controller first sends a "negative ion working" message every 100ms, and the negative ion generator starts working. When it needs to be turned off, upon receiving the "negative ion status" message, the thermal management controller sends a "negative ion off" message every 100ms, turning off the negative ion generator.

[0069] During negative ion activation, if the concentration of fine particulate matter is too high, the internal and external circulation motors need to be controlled. When the thermal management controller receives a value indicating that the concentration of fine particulate matter inside or outside the vehicle exceeds a preset value, if the outdoor temperature is below 24°C, the air circulation damper is adjusted to external circulation, and the air conditioning display status remains unchanged; if the outdoor temperature is above 24°C, the air circulation damper is adjusted to full internal circulation, and the air conditioning display status remains unchanged. If the thermal management controller receives a value indicating that the concentration of fine particulate matter inside or outside the vehicle is below a preset value, the air purification function is deactivated.

[0070] Optionally, in one embodiment, after the step of controlling the compressor, the heating / cooling damper, and the blower to enter the defrost / defogging mode, the following is included:

[0071] When the concentration of fine particulate matter in the passenger cabin is greater than the preset value, if the air conditioner is in non-AUTO and non-defrost / defogging mode, the thermal management controller will control the operation of the internal and external circulation motors. When the internal circulation operation time of the internal circulation motor reaches the first preset time, it will switch to external circulation operation for the second preset time, and the first preset time is longer than the second preset time.

[0072] In this embodiment, when the concentration of fine particulate matter in the passenger cabin exceeds a preset value, the air purification function needs to be activated. At this time, if the air conditioner is in non-AUTO and non-defrost mode, the thermal management controller controls the operation of the internal and external circulation motors, and the thermal management controller activates the negative ion generator. In this embodiment, taking a first preset duration of 15 minutes and a second preset duration of 1 minute as an example, when the internal circulation motor has been running for 15 minutes, it switches to external circulation for 1 minute. When the concentration of fine particulate matter in the passenger cabin is less than the preset value, the internal and external circulation motors are no longer controlled, and the negative ion generator is not activated for purification.

[0073] In one embodiment, when the concentration of fine particulate matter in the passenger cabin is greater than a preset value, if the air conditioner is in AUTO or defrost mode, the internal and external circulation motors will adjust accordingly. That is, since the air conditioner operates in automatic or defrost mode, the internal and external circulation motors will adjust accordingly.

[0074] Optionally, in one embodiment, after the step of executing the control strategy corresponding to the demand via the thermal management controller, the method includes:

[0075] If the control strategy corresponding to the requirement fails to execute successfully, then check whether each component corresponding to the control strategy is faulty.

[0076] In this embodiment, after determining the passenger cabin's needs, when the thermal management controller executes the control strategy corresponding to the passenger cabin's needs, if the control strategy corresponding to the passenger cabin's needs is not executed successfully, for example, if the passenger cabin's needs are determined to be cooling needs, and the thermal management controller executes the control strategy corresponding to the cooling needs, if the passenger cabin cannot be cooled, then the various components corresponding to the corresponding control strategy are checked for malfunctions.

[0077] Specifically, when the blower is operating, the blower speed feedback pin is checked. If the feedback blower speed value is not within the target range, the blower is stopped, and the thermal management controller sends a blower fault message to the main unit's large screen. When the compressor is operating, the compressor speed feedback pin is checked. If the feedback compressor speed value is not within the target range, the compressor is stopped, and the thermal management controller sends a compressor fault message to the main unit's large screen. When the internal and external circulation motors and the temperature mixing damper are operating, it is checked whether the internal and external circulation motors have not rotated to the corresponding positions for an extended period. If the internal and external circulation motors have not rotated to the corresponding positions for an extended period, the internal and external circulation motors are stopped, and the thermal management controller sends a stall fault message to the main unit's large screen.

[0078] When the AD interface of the thermal management controller detects a temperature outside the normal range, the thermal management controller generator sends the temperature sensor readings to the vehicle's main unit screen, making passengers aware of the passenger compartment temperature and enabling them to make the correct judgment.

[0079] When the thermal management controller's AD interface detects that the temperature and humidity are outside the normal range, the thermal management controller sends the humidity sensor data to the vehicle's main unit screen, making passengers aware of the humidity in the passenger compartment and enabling them to make the correct judgment.

[0080] When the thermal management controller's power supply voltage is detected to be out of range, the thermal management controller system enters standby mode, sends a voltage abnormality signal to the car's large screen display, and controls the thermal management controller to stop working.

[0081] When the thermal management controller receives a checksum error from the master node's LIN message, it sends a LIN communication error message to the vehicle's main unit display to ensure the vehicle owner is aware of the fault information. The checksum, in data processing and communication, is used to verify the sum of a set of data items at a destination.

[0082] When the thermal management controller receives a CAN message checksum error from the master node, it sends a CAN communication error message to the vehicle's main unit screen for display, ensuring that the vehicle owner is aware of the fault information.

[0083] Optionally, in one embodiment, reference is made to Figure 4 , Figure 4 This is a flowchart illustrating the second embodiment of the functional control method for the thermal management controller of the present invention. Figure 4 As shown, the functional control method based on the thermal management controller includes:

[0084] Step S40: When a ventilation command is received, if the outside temperature is within the first preset temperature range or the third preset temperature range, the thermal management controller controls the internal and external circulation motors to perform external circulation.

[0085] Step S50: If the outside temperature is within the second preset temperature range, the thermal management controller controls the external circulation motor to circulate for a third preset time and controls the servo motor to be in a half-open position for a fourth preset time.

[0086] In step S60, if the outside temperature is within the fourth preset temperature range, the thermal management controller controls the internal and external circulation motors to circulate for a fifth preset duration, and controls the servo motor to remain in a half-open position for a sixth preset duration.

[0087] In this embodiment, to avoid prolonged internal circulation and a stuffy environment, it is necessary to switch to external circulation periodically to allow fresh air in. The thermal management controller controls the internal and external circulation motors to operate in internal circulation mode for a certain period of time, then switches to external circulation for ventilation, and then switches back to internal circulation.

[0088] Specifically, taking a first preset temperature range of (-∞, 5]℃, a second preset temperature range of (5, 10]℃, a third preset temperature range of (10, 20]℃, a fourth preset temperature range of (20, +∞]℃, a third preset duration of 10 min, a fourth preset duration of 2 min, a fifth preset duration of 5 min, and a sixth preset duration of 1 min as an example, when a ventilation command is received, if the outside temperature is within the range of (-∞, 5]℃ or (10, 20]℃, the thermal management controller controls the internal and external circulation motors to perform external circulation; if the outside temperature is within the range of (5, 10]℃, the thermal management controller controls the internal and external circulation motors to perform external circulation for 10 min and keeps the servo motor in a half-open position for 2 min; if the outside temperature is within the range of (20, +∞]℃, the thermal management controller controls the internal and external circulation motors to perform internal circulation for 5 min and keeps the servo motor in a half-open position for 1 min. It is easy to understand that the parameters in this embodiment are for reference only and are not intended to be limiting.

[0089] Secondly, embodiments of the present invention also provide a functional control system for a thermal management controller.

[0090] In one embodiment, reference is made to Figure 5 , Figure 5 This is a functional module diagram of an embodiment of the thermal management controller of the present invention. Figure 5 As shown, the functional control system of the thermal management controller includes:

[0098] When the humidity in the passenger cabin exceeds the first humidity threshold, the passenger cabin's demand is determined to be a dehumidification demand.

[0099] When the humidity in the passenger cabin is less than the second humidity threshold, the passenger cabin's demand is determined to be a humidification demand, where the first humidity threshold is greater than the second humidity threshold.

[0100] When there is frost and / or fog on the windshield or left and right rearview mirrors of the passenger compartment, the passenger compartment’s demand is determined to be a defrosting and defogging demand.

[0102] Optionally, in one embodiment, the thermal management controller 30 is specifically configured to:

[0103] When the passenger cabin requires cooling, the thermal management controller starts the heating and cooling damper motor, the internal and external circulation motor, the compressor, and the blower.

[0104] When the passenger cabin requires heating, adjust the WPTC power and control the start of the warm air pump, shut-off valve, hot and cold air damper motor, and internal and external circulation motor.

[0105] When the passenger cabin requires dehumidification, the thermal management controller activates the air conditioning blowing mode and opens the windows.

[0110] When the concentration of fine particulate matter in the passenger cabin is greater than the preset value, if the air conditioner is in non-AUTO, non-defrost mode, the thermal management controller will control the internal and external circulation motors to perform internal circulation. When the internal circulation time of the internal and external circulation motors reaches the first preset time, it will switch to external circulation for the second preset time, and the first preset time is longer than the second preset time.

[0111] Optionally, in one embodiment, the functional control system of the thermal management controller further includes a detection module configured to:

[0112] If the control strategy corresponding to the requirement fails to execute successfully, then check whether each component corresponding to the control strategy is faulty.

[0113] Optionally, in one embodiment, the thermal management controller 30 is further configured to:
