[0021] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.
[0022] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.
[0023] It should be noted that the execution subject of this embodiment can be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device capable of realizing the above functions, an air conditioning thermal management dual temperature zone collaborative control device, etc. The following takes the air conditioning thermal management dual temperature zone collaborative control device as an example to illustrate this embodiment and the following embodiments.
[0024] Based on this, the embodiment of the present application provides an air conditioning thermal management dual temperature zone coordinated control method, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the dual-temperature zone collaborative control method for air conditioning thermal management of the present application.
[0025] In this embodiment, the air conditioning thermal management dual-temperature zone coordinated control method includes steps S10 to S30: Step S10, obtaining the target air outlet temperature and obtaining the opening status of the dual-temperature zone air conditioner; It should be noted that the target air outlet temperature refers to the air outlet temperature that the air conditioning system expects to reach after being set by the user or automatically adjusted. This temperature is the benchmark of the air conditioning system control algorithm and is used to guide cooling or heating operations; The dual-zone air conditioning system allows different temperatures to be set for different areas in the car (such as the driver and passenger areas). "Getting the dual-zone air conditioning on status" means that the system needs to detect and confirm whether the dual-zone function is activated, and then adjust the control algorithm according to the dual-zone on status to independently control the target air outlet temperature of the main driver and co-pilot areas.
[0026] It should be understood that when the dual temperature zone function is turned on, the system needs to independently control the damper position and temperature adjustment equipment of each zone to meet the temperature requirements of different zones.
[0027] In a specific implementation, the target air outlet temperature can be calculated by a two-dimensional table lookup of the set temperature and the ambient temperature.
[0028] In a feasible implementation manner, step S10 includes steps A11-A12: Step A11: Obtain design temperature, vehicle interior temperature, ambient temperature, sunlight intensity, and preset calibration coefficient; It should be noted that the design temperature refers to the desired temperature set by the user through the air-conditioning control panel, the interior temperature refers to the actual temperature inside the vehicle, the ambient temperature refers to the current temperature outside the vehicle, that is, the temperature of the environment outside the vehicle, the sunlight intensity refers to the intensity or radiation of the sunlight shining on the vehicle, and the preset calibration coefficients are obtained through experimental calibration during the system design and testing phases, and are used to adjust the target air outlet temperature in the temperature control algorithm.
[0029] By precisely controlling these parameters, the automotive air conditioning system can achieve more comfortable, energy-efficient and intelligent temperature management, improving the driving experience of passengers.
[0030] Step A12: Determine the target air outlet temperature according to the design temperature, ambient temperature, vehicle interior temperature, sunlight intensity, vehicle interior temperature and a preset calibration coefficient.
[0031] In the specific implementation, the following formula is used: TempTarget= TempTarget1+ TempTarget2+ TempTarget3 =A* TempSet +B* TempAmb+C*Q+ D*(TempSet- TempIncar)+E The target air outlet temperature is calculated, where TempSet is the set temperature, TempIncar is the temperature inside the car, TempAmb is the ambient temperature, TempTarget is the target air outlet temperature, Q is the sunlight intensity, and A, B, C, D, and E are calibration coefficients.
[0032] Wherein, TempTarget1 is determined by the following Table 1 and the following formula: TempTarget1= A* TempSet +B* TempAmb Among them, A and B change with the ambient temperature and are test calibration quantities. The following table lookup algorithms are all two-dimensional linear interpolation table lookup algorithms. Among them, the horizontal axis of Table 1 is the ambient temperature and the vertical axis is the set temperature: Table 1
[0033] Wherein, TempTarget2 is determined by the following Table 2 and the following formula: TempTarget2= C*Q Among them, this part is to compensate the target air outlet temperature through the sunlight sensor. C changes with the ambient temperature. The horizontal axis of Table 2 is the ambient temperature and the vertical axis is the irradiance: Table 2
[0034] Wherein, TempTarget3 is determined by the following Table 3 and the following formula: TempTarget3=D*(TempSet-TempIncar) Among them, this part is to compensate the target outlet temperature by the difference between the in-car temperature and the set temperature. D changes with the ambient temperature and is a calibration quantity. The horizontal axis of Table 3 is the ambient temperature, and the vertical axis is the difference between the set temperature and the in-car temperature: Table 3
[0035] Step S20, turning on the corresponding temperature adjustment device according to the target air outlet temperature, and setting the target adjustment temperature according to the turning-on state of the dual-temperature zone air conditioner to perform temperature adjustment, wherein the target adjustment temperature includes a target evaporation temperature and / or a warm air temperature; It should be noted that the corresponding temperature control device is turned on according to the target air outlet temperature, that is, the compressor, heater or other temperature control device is turned on to achieve the calculated target air outlet temperature. For example, if the target temperature is low, the compressor is turned on for cooling; if the target temperature is high, the heater is turned on for heating.
[0036] It should be understood that the target evaporation temperature: for the refrigeration system, the target evaporation temperature is set, which is the target temperature when the refrigerant evaporates in the evaporator; the warm air temperature for the heating system, the target warm air temperature is set, which is the target temperature of the output air of the warm air system.
[0037] It is understood that temperature regulation uses a proportional-integral-derivative (PID) control algorithm to adjust the temperature to ensure that the actual outlet air temperature is close to the target outlet air temperature, including: Proportional control: adjust the output according to the current error (the difference between the target and the actual).
[0038] Integral control: eliminates steady-state errors and ensures long-term stability.
[0039] Derivative control: predicts error trends and reduces overshoot and oscillation.
[0040] In a feasible implementation, step S20 includes steps A21-A22: Step A21: When it is determined that the dual-temperature air conditioner is not turned on, three temperature sections are set to control the target air outlet temperature, and the three temperature sections include a first temperature range, a second temperature range, and a third temperature range; It should be noted that the first temperature range, the second temperature range and the third temperature range are three continuous ranges and can be calibrated.
[0041] In the specific implementation, when the dual-zone air conditioner is not turned on, the target air outlet temperature is divided into three sections: 3-14, 14-30, and 30-65 and controlled separately.
[0042] Step A22: when it is determined that the target air outlet temperature is within the first temperature range, the compressor is turned on for cooling, and the first target evaporation temperature is set for cooling; In a specific implementation, when the target temperature is between 3 and 14, only the compressor is turned on for cooling, and the first target evaporating temperature = the target air outlet temperature - 2.
[0043] Step A23: when it is determined that the target air outlet temperature is within the second temperature range, the compressor is turned on for cooling and the electric heater is turned on for heating, and the second target evaporation temperature and the first warm air temperature are set for heating and cooling; In a specific implementation, when the target temperature is between 14 and 25 degrees Celsius, the second target evaporation temperature is 10 degrees Celsius and the first warm air temperature is 32 degrees Celsius.
[0044] Step A24: when it is determined that the target air outlet temperature is within the third temperature range, turning on the electric heater for heating and setting the second warm air temperature for heating; In a specific implementation, when the target temperature is between 25-65, the second warm air temperature = the outlet air target temperature + 3.
[0045] In another feasible implementation, step S20 includes steps A31 to A34: Step A31: When it is determined that the dual-temperature air conditioner is turned on, the main driving target temperature and the co-driving target temperature are obtained, and three temperature sections are set to control the target air outlet temperature, where the three temperature sections include a first temperature range, a second temperature range, and a third temperature range; It should be noted that the first temperature range, the second temperature range and the third temperature range are three continuous ranges and can be calibrated.
[0046] In the specific implementation, when the dual-zone air conditioner is turned on, the target air outlet temperature is also divided into three sections: 3-14, 14-30, and 30-65 and controlled separately.
[0047] Step A32: when it is determined that the main driving target temperature is within the first temperature range, the compressor is turned on for cooling and the electric heater is turned on for heating, and a third target evaporation temperature and a third warm air temperature are set for heating and cooling; In the specific implementation, when the main driver target temperature is between 3-14, the compressor cooling is turned on, the third target evaporating temperature = MIN (main driver air outlet target temperature, co-driver air outlet target temperature) - 2, and the third warm air temperature is 32.
[0048] Step A33: when it is determined that the main driving target temperature is within the second temperature range, the compressor is turned on for cooling and the electric heater is turned on for heating, and a fourth target evaporation temperature and a fourth warm air temperature are set for heating and cooling; In a specific implementation, when the main driving target temperature is between 14-25, the fourth target evaporation temperature is 10 and the fourth warm air temperature is 32.
[0049] Step A34: When it is determined that the target air outlet temperature is within the third temperature range, the compressor is turned on for cooling and the electric heater is turned on for heating, and the fifth warm air temperature is set for heating.
[0050] In a specific implementation, when the main driver target temperature is between 25-65, the fifth warm air temperature = MAX (main driver target air outlet temperature, co-driver target air outlet temperature) + 3.
[0051] It should be noted that the air conditioning control algorithm of the open-loop control damper needs to use the outlet temperature sensor for precise control, because the evaporation temperature and the heater core temperature of the cold and heat sources of electric vehicles are often not accurately controlled. In the case of the outlet temperature failure, the evaporation temperature and the heater core temperature (warm air temperature) are used to control the air mixing of the damper to achieve the purpose of accurately controlling the outlet temperature.
[0052] Step S30, controlling the air door opening state according to the opening state of the dual-zone air conditioner.
[0053] It should be noted that controlling the damper opening state according to the opening state of the dual-zone air conditioner is to meet the temperature requirements of passengers in different areas and ensure that the temperature in each area can meet the comfort requirements of the passengers.
[0054] It should be understood that, based on the target air outlet temperature of each zone, the system will adjust the position of the damper to control the air flow direction and mixing ratio to ensure that the temperature of each zone meets the setting.
[0055] In a feasible implementation manner, after step S30, steps A41 to A42 are further included: Step A41: upon receiving a heating request from the passenger compartment and a heating request from the battery pack, obtaining an outlet water temperature difference of the electric heater; It should be noted that the difference between the water temperature at the outlet of the electric heater and the target heating temperature is measured, and this difference is one of the inputs of the PID control algorithm.
[0056] In a specific implementation, a temperature sensor is used to monitor the water temperature at the outlet of the electric heater in real time, and the temperature is compared with the preset target temperature to calculate the difference.
[0057] Step A42: determining corresponding proportional parameters, integral parameters and differential parameters according to the outlet water temperature difference; It should be noted that, according to the outlet water temperature difference, the proportional parameter (Kp), integral parameter (Ki) and differential parameter (Kd) suitable for the current working conditions are determined from the table lookup or preset parameters.
[0058] In the specific implementation, the PID parameters suitable for the current temperature difference are calculated by looking up a table or using an algorithm. These parameters may change with the change of the temperature difference to adapt to different heating requirements and improve control accuracy.
[0059] Step A43: Control the heat distribution three-way proportional water valve according to the proportional parameter, integral parameter and differential parameter to complete the heating of the passenger compartment and the battery pack.
[0060] It should be noted that the determined PID parameters are used to control the three-way proportional water valve to adjust the flow of hot water to the passenger compartment and the battery pack to ensure that both can achieve the desired heating effect.
[0061] In the specific implementation, proportional control (P): according to the current outlet water temperature difference, directly adjust the opening of the water valve to reduce the temperature difference.
[0062] Integral control (I): accumulates past temperature differences to eliminate steady-state errors and ensure long-term heating stability.
[0063] Differential control (D): Predict the changing trend of temperature difference and adjust the opening of the water valve in advance to reduce overshoot and oscillation of the system.
[0064] It should be understood that when the air conditioner thermal management has PTC heating (PTC heater, full name is positive temperature coefficient heater, is a semiconductor ceramic heating element, the resistance of the PTC heater increases with the increase of temperature, to achieve automatic temperature adjustment to prevent overheating.) or compressor heat pump, and the battery thermal management has PTC heating or compressor heat pump, the heat source distribution three-way proportional water valve is controlled as follows: PID type (incremental): Control object: PTC outlet water temperature; Control target: warm core target water temperature (sent by CCM); Control accuracy: ±1℃ PID; Calculation cycle: 2000ms; PID parameters: Kp, Ki, Kd.
[0065] Calculate by looking up the table according to Table 4 below. The parameters in this table are calibrated by the calibration test personnel. The table lookup algorithm uses a two-dimensional linear interpolation algorithm) (target water temperature - outlet water temperature): Table 4
[0066] The present embodiment provides a dual-zone collaborative control method for air conditioning thermal management, which obtains a target air outlet temperature and a dual-zone air conditioner on state; turns on a corresponding temperature adjustment device according to the target air outlet temperature, and sets a target adjustment temperature according to the dual-zone air conditioner on state to perform temperature adjustment, wherein the target adjustment temperature includes a target evaporation temperature and / or warm air temperature; controls the damper opening state according to the dual-zone air conditioner on state, reasonably opens the cold source and the heat source, and collaboratively controls actuators such as the electronic expansion valve, the heat source distribution three-way water valve, and the temperature damper, so as to reasonably distribute the cold and heat sources, save energy, control the damper opening in a closed loop, and greatly improve comfort.
[0067] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the above-mentioned embodiment 1 can be referred to the above introduction, and will not be repeated in the following. Figure 2 , step S30 includes steps S301~S302: Step S301, when it is determined that the dual-temperature air conditioner is in the on state, the difference between the current outlet set temperature and the actual outlet temperature, the difference between the previous set temperature and the actual temperature, the current damper position, and the adjustment control algorithm calibration amount are obtained; In a specific implementation, the difference (ΔT_k) between the set temperature and the actual temperature of the air outlet at the current moment is obtained.
[0068] Get the difference between the set temperature and the actual temperature of the air outlet at the previous moment (ΔT_{k-1}).
[0069] Get the current position of the damper (TempPos_M).
[0070] Get the calibration quantity of the regulation control algorithm, that is, the PID parameters (Kp, Ki, Kd).
[0071] Step S302, determining the air door change amount according to the difference between the current air outlet set temperature and the actual air outlet temperature, the difference between the previous set temperature and the actual temperature, and the calibration amount of the adjustment control algorithm; It should be noted that if the mode includes face blowing, the face blowing air outlet temperature sensor is used for closed-loop control of the air door opening; if the mode includes window blowing or foot blowing, the window blowing air outlet temperature sensor is used for closed-loop control; the left and right air door target position control adopts PID algorithm, with actual air outlet temperature - target air outlet temperature and its change as PID input; The temperature damper PID control algorithm is as follows and is executed every 100ms: ΔTempPos = Kp (ΔT_(k) – ΔT_(k - 1)) + Ki * ΔT_(k) + Kd Among them, ΔTempPos is the damper change; ΔT_(k) is the difference between the set temperature of the air outlet at this moment and the actual air outlet temperature; ΔT_(k - 1) is the difference between the set temperature and the actual temperature at the previous moment; TempPos_M is the damper position at this moment; TempPos is the damper position at the next moment; Kp / Ki / Kd is the algorithm calibration quantity.
[0072] Step S303, determining the target temperature damper position according to the damper change amount and the damper position at the current moment; In the specific implementation, the temperature damper position is calculated by the following formula: TempPos = ΔTempPos + TempPos_M Step S304, adjusting the servo motor to control the damper according to the target temperature damper position.
[0073] In the specific implementation, the temperature damper uses a servo motor, the servo motor feedback voltage is U, the motor target position is TempPos, the read position data is calculated by pid, and the PWM control motor is configured according to the calculation result.
[0074] It should be noted that before controlling the motor, initialization processing is required, including: Motor initialization: configure the timer to output PWM to control the motor; Encoder initialization: Configuring the timer can read the encoder count value; Timer initialization: Configuring the basic timer can generate a timer interrupt to perform PID calculations; PID parameter initialization: configure target value, actual value, error, integral term, proportional gain, integral gain and differential gain related parameters.
[0075] In the specific implementation, the target value is set and the motor is enabled; the motor rotates, and the encoder counts and feedbacks the PID closed-loop control: PID calculation is performed in the update interrupt callback function of TIM1 to limit the motor PWM duty cycle.
[0076] like Figure 3 As shown, the system receives an input of a target position, which is the predetermined position that the motor needs to reach; the target position is compared with the actual position of the motor to calculate the position error; the error signal is sent to the PID controller, which contains three links: Proportional link P: Generates a control signal based on the size of the current error.
[0077] Integral link I: Generate a control signal based on the accumulated amount (integral) of the error to eliminate the steady-state error.
[0078] Differentiation link D: Generates a control signal based on the rate of change (differential) of the error to predict the future trend of the error and reduce the overshoot of the system.
[0079] The output of the PID controller is used to generate a PWM (pulse width modulation) signal, the duty cycle of which determines the drive strength of the motor; the PWM signal drives the motor to rotate, and the actual position of the motor is monitored in real time by the encoder and fed back to the system; the encoder measures the rotation angle of the motor and feeds the actual position information back to the PID controller for comparison with the target position; the actual position information is returned to the error calculation link through the feedback loop to form a closed-loop control to ensure that the motor position can accurately track the target position; the current actual position of the motor is the output of the system and can be used for further monitoring or control.
[0080] It should be understood that this position loop control system can achieve precise control of the motor position through closed-loop feedback.
[0081] The present embodiment provides a dual-temperature zone collaborative control method for air conditioning thermal management. When it is determined that the dual-temperature air conditioner is in the on state, the difference between the current outlet set temperature and the actual outlet temperature, the difference between the previous set temperature and the actual temperature, the current damper position and the calibration amount of the adjustment control algorithm are obtained; the damper change amount is determined according to the difference between the current outlet set temperature and the actual outlet temperature, the difference between the previous set temperature and the actual temperature and the calibration amount of the adjustment control algorithm; the target temperature damper position is determined according to the damper change amount and the damper position at the current moment; the servo motor is adjusted according to the target temperature damper position to control the damper. The dual-temperature zone air conditioning system can accurately control the damper position to meet the temperature requirements of different areas, provide a comfortable driving environment, and improve energy utilization efficiency.
[0082] Based on the first and second embodiments of the present application, in the third embodiment of the present application, the same or similar contents as those in the above embodiments can be referred to the above introduction, and will not be described in detail later. Figure 4 , after step S30, further comprising steps S310 to S340: Step S310, when receiving a cooling request for the passenger compartment and a cooling request for the battery pack, adjusting the electronic expansion valve to a preset number of steps; It should be noted that when a cooling request is received for the passenger compartment and the battery pack, the electronic expansion valve is adjusted to a preset number of steps (i.e., opening degree) to provide a refrigerant flow for the initial cooling demand.
[0083] It should be understood that the minimum opening limit of the battery-side electronic expansion valve is 50 steps.
[0084] The maximum opening limit of the battery expansion valve changes with the maximum temperature of the battery, as shown in Table 5 below: Table 5
[0085] In a specific implementation, the electronic expansion valve receives a signal from a control unit and is adjusted to a preset position, which corresponds to a specific refrigerant flow rate to meet the initial cooling demand.
[0086] Step S320, obtaining the water temperature at the battery pack inlet; It should be noted that the water temperature at the inlet of the battery pack is monitored so that the cooling strategy can be adjusted according to the actual temperature.
[0087] In the specific implementation, a temperature sensor is used to monitor the water temperature at the battery pack inlet in real time and use it as the input of the control algorithm.
[0088] Step S330, when the water temperature at the battery pack inlet is lower than the first preset temperature, closing the electronic expansion valve at a first preset speed; It should be noted that when the water temperature at the battery pack inlet is lower than a preset safety or efficiency threshold, the refrigerant flow to the battery pack is reduced to prevent overcooling.
[0089] It should be understood that when the passenger compartment and the battery pack simultaneously issue a compressor cooling request, the electronic expansion valve is first adjusted to an opening of 50 steps. This preset number of steps is based on the standard setting of dual cooling and dehumidification to ensure that both the battery pack and the passenger compartment can be properly cooled in the initial state; If the water temperature at the battery pack inlet is lower than the first preset temperature, the control unit will reduce the opening of the electronic expansion valve at a first preset speed (slower), thereby reducing the refrigerant flow to the battery pack.
[0090] In a specific implementation, when the water temperature at the battery pack inlet is lower than 20 degrees, the electronic expansion valve is gradually closed at a speed of 5 steps per second.
[0091] Step S340, when the water temperature at the battery pack inlet is higher than the first preset temperature, the electronic expansion valve is opened at a second preset speed to complete the cooling of the passenger compartment and the battery pack.
[0092] It should be noted that when the water temperature at the battery pack inlet is higher than a preset threshold, the refrigerant flow to the battery pack is increased to provide more cooling.
[0093] It should be understood that if the water temperature at the battery pack inlet is higher than the first preset temperature, the control unit will increase the opening of the electronic expansion valve at a second preset speed (faster), thereby increasing the refrigerant flow to the battery pack.
[0094] In a specific implementation, when the water temperature at the battery pack inlet is higher than 20 degrees, the electronic expansion valve is gradually opened at a speed of 10 steps / second.
[0095] It is understandable that this strategy prioritizes ensuring temperature regulation of the passenger compartment and appropriately meeting the temperature condition requirements of the battery pack.
[0096] This embodiment provides an air conditioning thermal management dual-temperature zone coordinated control method. The automobile air conditioning system can dynamically adjust the refrigerant flow rate according to the actual temperature requirement of the battery pack to ensure that the passenger compartment and the battery pack are properly cooled, while improving energy utilization efficiency and protecting the battery pack from excessively high or low temperatures, which helps to optimize the performance and battery life of electric vehicles.
