With socioeconomic development, consumer awareness of consumption and enjoyment is increasing, leading to higher demands for comfort in commercial vehicles. Truck drivers in southern China often use air conditioning to cool down during summer transports while waiting for deliveries. To save money, long-distance drivers sleep in their vehicles at night, requiring air conditioning. However, running the engine for cooling causes wear and fuel consumption, and continuously emits exhaust gas, which pollutes the cabin. Consequently, there is a need for cabin cooling without the engine running. Currently, commercial vehicle OEMs and aftermarket manufacturers rely on either roof-mounted parking air conditioners (which occupy the sunroof, are incompatible with the vehicle's original air conditioning, and are independent of the vehicle's original air conditioning, resulting in two independent air conditioning systems and high costs) or dual-mode parking air conditioners (which connect a traditional compressor and an electric parking compressor in parallel, resulting in a complex structure and numerous pipe connections, posing a high risk of leakage). The commercial vehicle air conditioning system uses a traditional compressor to drive the refrigerant to flow in the air conditioning pipes. The power source of the traditional compressor is the engine main shaft connected by a belt to drive the traditional compressor clutch to rotate. During driving, the compressor speed is not controlled by the air conditioning control system, resulting in excess cooling capacity when the air conditioning is turned on most of the time during driving, and high fuel consumption.

[0020] It should be understood that the specific embodiments described herein are merely used to explain the technical solutions of the present application and are not intended to limit the present application.

[0021] 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.

[0022] The main solution of the embodiment of the present application is: when the target vehicle is in a driving condition, the compressor clutch is controlled to engage and the current indoor temperature is detected according to the air-conditioning start instruction; the difference between the current indoor temperature and the air-conditioning set temperature is calculated to obtain a target temperature difference; and the driving air-conditioning of the target vehicle is controlled according to the driving air-conditioning control strategy corresponding to the driving condition and the target temperature difference.

[0023] Currently, commercial vehicle OEMs and the aftermarket utilize either roof-mounted parking air conditioners (which occupy the sunroof, are incompatible with sunroof configurations, and are unconnected to the original vehicle's air conditioning, resulting in two independent air conditioning systems and high costs) or dual-mode parking air conditioners (which utilize a traditional compressor and an electric parking compressor in parallel, resulting in a complex structure and numerous pipe connections, posing a high risk of leakage). These commercial vehicle on-board air conditioning systems use a traditional compressor to drive the refrigerant through the air conditioning lines. The compressor's power source is the engine's main shaft, which drives the clutch through a belt connection. During driving, the compressor speed is not controlled by the air conditioning control system, resulting in excess cooling capacity and high fuel consumption during most of the driving cycle.

[0024] This application controls the compressor clutch engagement and detects the current indoor temperature based on an air conditioning start command when the target vehicle is in the driving state. The application then calculates the difference between the current indoor temperature and the air conditioning set temperature to obtain a target temperature difference. The target vehicle's driving and parked air conditioning is then controlled based on the driving air conditioning control strategy corresponding to the driving state and the target temperature difference. The motor speed is dynamically adjusted based on the difference between the user's air conditioning temperature set point and the actual indoor temperature to achieve compressor speed changes, thereby reducing fuel consumption for both driving and parked air conditioning and achieving rapid and precise air conditioning temperature control.

[0025] It should be noted that the execution subject of this embodiment can be a computing service device with data processing, network communication, and program execution capabilities, such as a tablet computer, personal computer, or mobile phone, or a commercial vehicle air conditioning control device capable of performing the aforementioned functions. This embodiment and the following embodiments will be described below using a commercial vehicle air conditioning control device as the execution subject.

[0026] Based on this, the embodiment of the present application provides a commercial vehicle parking air conditioning control method, referring to Figure 1 , Figure 1 This is a flow chart of a first embodiment of a method for controlling stationary air conditioning in a commercial vehicle according to the present application.

[0027] In this embodiment, the commercial vehicle parking air conditioning control method includes steps S10 to S30: Step S10, when the target vehicle is in a driving state, controlling the compressor clutch to engage according to the air-conditioning start instruction and detecting the current indoor temperature; It should be noted that currently all commercial vehicle OEMs and aftermarket adopt roof-mounted parking air conditioners (occupying the sunroof, not compatible with the sunroof configuration, unrelated to the original vehicle air conditioner, two independent air conditioning systems, high cost) or dual-mode parking air conditioners (traditional compressor and parking electric compressor in parallel, complex structure, multiple pipe interfaces and high risk of leakage) technology routes. The schematic diagram of the dual-mode parking air conditioner is shown below. Figure 2 As shown, it includes an electric compressor, a traditional compressor, a drive controller, a one-way valve, a condenser, an electric fan, an evaporator and an expansion valve.

[0028] It should be noted that the stationary integrated air conditioning system architecture in this embodiment consists of a condenser, an engine fan / electronic fan, an air conditioning box (evaporator, blower, thermal expansion valve, etc.), and a stationary integrated compressor. The principle is as follows: Figure 3 As shown, the principle is: the final output speed of the compressor is determined by the clutch direct drive speed + the electric compressor speed.

[0029] It can be understood that the target vehicle refers to a commercial vehicle with an integrated mobile air-conditioning system architecture, and the air-conditioning on command refers to the command issued by the user to turn on the air-conditioning. The user can issue the air-conditioning on command through buttons or voice, etc. This embodiment does not limit this. The current indoor temperature refers to the temperature in the cab when the air-conditioning is turned on.

[0030] In a specific implementation, when the vehicle is in driving condition, the air-conditioning start command issued by the user controls the compressor clutch to engage, so that the compressor is driven by the vehicle engine to rotate, and then the temperature in the cab is detected to obtain the current indoor temperature.

[0031] Step S20, calculating the difference between the current indoor temperature and the air conditioner set temperature to obtain a target temperature difference; It can be understood that the air conditioning set temperature refers to the air conditioning temperature value set by the user, and the target temperature difference refers to the difference between the air conditioning temperature set by the user under driving conditions and the actual indoor temperature.

[0032] In specific implementation, in order to achieve rapid and accurate control of the air-conditioning temperature, this embodiment controls the speed of the motor through the difference between the user's air-conditioning temperature setting value and the actual indoor temperature, thereby achieving dynamic control of the compressor speed. That is, in driving conditions, the compressor is driven by the vehicle engine to rotate, and the compressor speed is adjusted in combination with the speed of the motor.

[0033] Step S30 , controlling the on-board air conditioning of the target vehicle according to the on-board air conditioning control strategy corresponding to the driving condition and the target temperature difference.

[0034] It can be understood that the driving air conditioning control strategy refers to the mapping relationship between the temperature difference of the driving conditions and the speed of the electric compressor (motor).

[0035] In a specific implementation, when the vehicle is driving, the air conditioner is turned on, the compressor clutch is engaged, and the engine drives the compressor. The cabin air conditioning control system dynamically adjusts the motor speed based on the difference between the user's air conditioning temperature setting and the actual indoor temperature. Ultimately, the compressor speed (motor speed + clutch speed) changes to meet the user's cooling capacity requirements at different time periods while also saving fuel. The driving air conditioning control system strategy is shown in Table 1. In this embodiment, the driving air conditioning control system strategy can be determined based on engineer experience or laboratory test data, and this embodiment is not limited to this.

[0036] Table 1:

[0037] In a feasible implementation, step S30 may include steps A11 to A12: Step A11, determining a target motor speed according to the driving air conditioning control strategy corresponding to the driving condition and the target temperature difference; It should be noted that the target motor speed refers to the motor speed corresponding to the target temperature difference.

[0038] In the specific implementation, after obtaining the mapping relationship between the driving operating temperature difference and the electric compressor (motor) speed, the mapping relationship is traversed through the difference between the user's air-conditioning temperature setting value and the actual indoor temperature to obtain the motor speed corresponding to the target temperature difference.

[0039] Step A12: Controlling the parking air conditioner of the target vehicle according to the clutch speed and the target motor speed.

[0040] It can be understood that the clutch speed refers to the speed at which the engine drives the compressor clutch.

[0041] In the specific implementation, the speed of the air-conditioning compressor is jointly controlled according to the speed of the engine driving the compressor clutch and the speed of the electric motor corresponding to the target temperature difference, so as to realize the control of the vehicle's parked air conditioning, that is, the dynamic control of the compressor speed is realized through the clutch speed and the electric motor speed.

[0042] In a feasible implementation manner, step S30 may further include steps B11 to B13: Step B11, obtaining compressor operating parameters, ambient temperature data, vehicle energy consumption data, and user behavior data; It is understandable that the compressor operating parameters include but are not limited to current, speed, operating resistance, etc., the ambient temperature data includes but is not limited to the temperature inside the vehicle, the set temperature and the external ambient temperature, etc., the vehicle energy consumption data records the power consumption or fuel consumption of the air-conditioning system in driving and parking modes, and the user behavior data includes but is not limited to user preference settings (frequency of selecting standard mode / energy-saving mode), usage time and other information.

[0043] Step B12: performing a simulation test on the target vehicle according to the compressor operating parameters, the ambient temperature data, the vehicle energy consumption data, and the user behavior data to obtain strategy optimization data; It is understandable that the strategy optimization data refers to optimization data for optimizing the driving air conditioning control strategy and / or the parking air conditioning control strategy.

[0044] In practice, the system simulates air conditioning control in commercial vehicles under driving and parking conditions, using compressor operating parameters, ambient temperature data, vehicle energy consumption data, and user behavior data. The ideal performance indicators obtained in the laboratory are then compared with actual operating conditions to identify the causes of discrepancies. Based on these discrepancies, specific optimization measures are proposed, such as adjusting the speed threshold or air volume level of the electric compressor, to generate strategic optimization data.

[0045] Step B13: Optimizing the air-conditioning control strategy for each operating condition according to the strategy optimization data to obtain an optimized vehicle air-conditioning control strategy.

[0046] In specific implementation, the driving air-conditioning control strategy and / or the parking air-conditioning control strategy are optimized through laboratory test data to obtain the optimized vehicle air-conditioning control strategy (including the driving air-conditioning control strategy and / or the parking air-conditioning control strategy). This embodiment also updates the air-conditioning control strategy of each vehicle through remote OTA (Over-the-Air) dynamic and irregular upgrades.

[0047] In a feasible implementation manner, step S30 may further include steps C11 to C13: Step C11, obtaining the compressor operating speed and the compressor operating current; It can be understood that the compressor operating speed refers to the speed of the air-conditioning compressor when it is running, and the compressor operating current refers to the current of the air-conditioning compressor when it is running.

[0048] Step C12, analyzing the compressor operating speed and the compressor operating current to obtain the compressor operating resistance; It can be understood that the operating resistance of the compressor refers to the resistance value of the compressor during operation.

[0049] In practice, during operation, the operating resistance of a compressor's internal mechanical components may change due to wear, dust accumulation, or other factors. Monitoring the compressor's operating current and speed can indirectly reflect these changes. Under normal circumstances, there is a certain relationship between the compressor's current and speed. When internal resistance increases, the current required to maintain the same speed also increases. Therefore, by analyzing the changing trends of these two parameters, the compressor's health can be determined and potential faults identified.

[0050] Step C13: When the compressor operating resistance is not less than the compressor resistance threshold, generate compressor failure warning information.

[0051] It is understandable that the compressor resistance threshold refers to the critical resistance value used to determine whether the compressor is faulty, and the compressor fault warning information refers to the warning information used to remind the user of the compressor fault.

[0052] In a specific implementation, the resistance value of the compressor during operation is compared with the resistance critical value used to determine whether the compressor is faulty. When the resistance value of the compressor during operation is not less than the resistance critical value used to determine whether the compressor is faulty, it indicates that the operating resistance of the compressor is too large and there is a fault, and then an early warning message is generated to remind the user of the compressor fault. That is, the on-board integrated compressor can continuously monitor the internal operating current and speed of the compressor, identify the internal operating resistance, report the fault to the air-conditioning controller and instrument display, and remind the user to perform maintenance on the vehicle compressor.

[0053] This embodiment controls the compressor clutch engagement and detects the current indoor temperature based on an air conditioning start command when the target vehicle is in driving mode. The system then calculates the difference between the current indoor temperature and the air conditioning setpoint to obtain a target temperature difference. The target vehicle's driving and parked air conditioning is then controlled based on the driving air conditioning control strategy corresponding to the driving mode and the target temperature difference. The motor speed is dynamically adjusted based on the difference between the user's air conditioning setpoint and the actual indoor temperature to achieve compressor speed changes. This reduces fuel consumption during both driving and parked mode, while enabling rapid and precise air conditioning temperature control.

[0054] 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 embodiment 1 can be referred to the above introduction and will not be described in detail later. Figure 4 The commercial vehicle parking air conditioning control method further includes steps S11 to S13: Step S11, when the target vehicle is in a parking state, determining an air conditioning target temperature and an air conditioning operation mode according to an air conditioning start instruction; It is understood that the air conditioner target temperature refers to the target temperature set by the user for the air conditioner to reach, and the air conditioner operation mode refers to the air conditioner operation mode set by the user, including the standard mode and the energy-saving mode.

[0055] In a specific implementation, when the commercial vehicle is in a parking condition, the speed of the compressor is adjusted only by the speed of the motor, and then the target temperature of the air conditioner set by the user and the air conditioner operation mode set by the user are determined according to the air conditioner start command issued by the user.

[0056] Step S12, calculating the difference between the current indoor temperature and the air conditioning target temperature to obtain a temperature target difference; It can be understood that the current indoor temperature refers to the temperature in the driving cab in the parking condition, and the temperature target difference refers to the difference between the user's air-conditioning temperature setting value in the parking condition and the actual indoor temperature.

[0057] In a specific implementation, the difference between the temperature in the driver's cabin in the parking condition and the target temperature of the air conditioner set by the user is calculated, and then the difference between the user's air conditioner temperature setting value in the parking condition and the actual indoor temperature is obtained based on the calculation result.

[0058] Step S13 , controlling the parking air conditioning of the target vehicle according to the parking air conditioning control strategy corresponding to the parking condition, the temperature target difference, and the air conditioning operation mode.

[0059] It can be understood that the parking air conditioning control strategy refers to the mapping relationship between the temperature difference in the parking condition and the speed of the electric compressor (motor), including the parking standard control strategy and the parking energy-saving control strategy.

[0060] In specific implementation, when the vehicle is parked, the air conditioner is turned on, the low-voltage battery powers the electric motor, and the cabin air conditioning control system dynamically adjusts the electric motor speed based on the difference between the user's air conditioning temperature setting and the actual indoor temperature. This allows the compressor speed (motor speed) to vary to meet the user's cooling capacity needs at different times of day, while also saving fuel. Table 2 shows the parking air conditioning control system strategy. The control strategy has two modes for driving and parking conditions: standard and energy-saving. The user can switch between these two modes via the air conditioner controller. Energy-saving mode lowers the compressor speed and air volume, achieving ultimate energy savings.

[0061] Table 2:

[0062] In a feasible implementation, step S13 may include steps D11 to D13: Step D11, determining a target air conditioning control strategy according to the air conditioning operation mode and the parking air conditioning control strategy corresponding to the parking condition; It is understandable that the target air-conditioning control strategy refers to the air-conditioning control strategy of different air-conditioning modes in parking conditions.

[0063] In a specific implementation, based on the air-conditioning operation mode set by the user, an air-conditioning control strategy corresponding to the air-conditioning operation mode is selected from the parking air-conditioning control strategies corresponding to the parking condition as the target air-conditioning control strategy.

[0064] In a feasible implementation, step D11 may include steps E11 and E12: Step E11, when the air conditioning operation mode is the air conditioning standard mode, determining the target air conditioning control strategy as the parking standard control strategy according to the parking air conditioning control strategy corresponding to the parking condition; It can be understood that the parking standard control strategy refers to the control strategy of the air conditioning standard mode in the parking condition.

[0065] In a specific implementation, when the air-conditioning operation mode set by the user is the standard mode, the control strategy of the parking condition air-conditioning standard mode in the parking air-conditioning control strategy is determined as the target air-conditioning control strategy.

[0066] Step E12: When the air conditioning operation mode is the air conditioning energy-saving mode, determining the target air conditioning control strategy as the parking energy-saving control strategy according to the parking air conditioning control strategy corresponding to the parking condition.

[0067] It can be understood that the parking energy-saving control strategy refers to the control strategy of the air-conditioning energy-saving mode in the parking condition.

[0068] In a specific implementation, when the air-conditioning operation mode set by the user is the energy-saving mode, the control strategy of the parking condition air-conditioning energy-saving mode in the parking air-conditioning control strategy is determined as the target air-conditioning control strategy.

[0069] Step D12, determining a target motor speed according to the target temperature difference and the target air conditioning control strategy; It can be understood that the target motor speed refers to the motor speed corresponding to the parking condition and the temperature difference.

[0070] In a specific implementation, the difference between the user's air conditioning temperature setting value in the parking condition and the actual indoor temperature is used to traverse the air conditioning control strategy corresponding to the air conditioning operation mode to obtain the motor speed corresponding to the parking condition and the temperature difference.

[0071] Step D13: Controlling the stationary air conditioner of the target vehicle according to the target speed of the electric motor.

[0072] In specific implementation, the compressor speed is adjusted by the motor speed corresponding to the parking condition and the temperature difference, so that the compressor speed change (motor speed) can meet the user's cooling capacity requirements in different time periods while saving fuel consumption.

[0073] This embodiment determines the target air conditioning temperature and operating mode based on an air conditioning start command when the target vehicle is parked. The system calculates the difference between the current indoor temperature and the target air conditioning temperature to obtain a target temperature difference. The target air conditioning system is then controlled based on the parking air conditioning control strategy corresponding to the parking condition, the target temperature difference, and the air conditioning operating mode. By dynamically adjusting the motor speed based on the difference between the user's set air conditioning temperature and the actual indoor temperature during parking, the system achieves variable compressor speed, meeting the user's cooling capacity needs at different times while also saving fuel.

[0074] It should be noted that the above examples are only used to understand the present application and do not constitute a limitation on the commercial vehicle stationary air conditioning control method of the present application. More simple transformations based on this technical concept are all within the scope of protection of the present application.
