[0043] like Figure 1 As shown, this disclosure proposes a method for a parking air conditioner for automobiles, the method comprising:

[0044] Obtain the current vehicle status of the target vehicle;

[0045] Based on the current vehicle status of the target vehicle, determine whether the target vehicle meets the prerequisites for accessing the parking air conditioning.

[0046] If the target vehicle meets the prerequisites, the execution mode of the target vehicle's parking air conditioner is determined and the parking air conditioner is activated.

[0047] Specifically, the prerequisites include: the vehicle's voltage status is ON for low voltage and Ready for high voltage; the vehicle's parking gear is P and the vehicle's engine is not started; the starting charge of the parking air conditioner in EV mode is greater than the safety constant; and the starting charge of the parking air conditioner in HEV mode is greater than the forced power reserve charge.

[0048] like Figure 2 As shown, all prerequisites in this disclosure must be met before the parking air conditioning interface can be accessed. If any condition is not met, the vehicle's human-machine interface will remind the user, through voice and text, which condition has not yet been met.

[0049] Specifically, before determining the execution mode of the target vehicle's parking air conditioner, the process includes:

[0050] The temperature and humidity information of the target vehicle are obtained, and the parking air conditioning usage time of the target vehicle is determined.

[0051] Specifically, before determining the execution mode of the target vehicle's parking air conditioner, the process also includes:

[0052] Adjustments were made to the parking comfort of the target vehicle.

[0053] Specifically, adjusting the parking comfort of the target vehicle includes:

[0054] Detect the seat status of the target vehicle and adjust the seat of the target vehicle to the parking position;

[0055] Detect the status of the headlights and windshield wipers of the target vehicle, and turn off the headlights and windshield wipers of the target vehicle;

[0056] Adjust the windows and locks of the target vehicle to parking mode.

[0057] Specifically, the target vehicle's parking air conditioning system operates in two modes: intelligent mode and ventilation mode.

[0058] In this embodiment, after entering the parking air conditioning, the air conditioning is turned on and enters the intelligent or ventilation mode. The temperature inside the vehicle is detected and the temperature is set. The load movement status of HVAC, the power of PTC, and the power of compressor are calculated according to the parking air conditioning temperature algorithm. The air conditioning energy consumption is obtained according to each status. The actual parking air conditioning usage time is obtained by subtracting the air conditioning energy consumption from the total vehicle power and the signal is fed back to the vehicle to inform the user of the usage time.

[0059] After entering the parking position, the headlights and wipers automatically turn off. The vehicle can be locked by voice commands but not unlocked. The key inside the car can lock the car normally. However, the windows cannot be raised or lowered by voice commands. The power tailgate cannot be opened from the outside.

[0060] Specifically, when the parking air conditioner of the target vehicle is in smart mode:

[0061] The internal air circulation control of the target vehicle is automatically adjusted according to the air outlet temperature;

[0062] The opening of the mixing damper of the target vehicle is adjusted according to the water temperature and evaporator temperature;

[0063] The air outlet mode of the target vehicle is controlled according to the temperature of the air outlet.

[0064] Specifically, the ventilation strategy of the target vehicle is implemented based on glass temperature, dew point temperature, and in-vehicle humidity.

[0065] In this embodiment, the working steps of the intelligent mode are as follows:

[0066] Internal and external air circulation control: The internal and external air circulation control mainly calculates the target opening of the damper according to the required air outlet temperature, and then automatically adjusts it. Normally, the air intake is in external air mode, that is, fresh air is drawn in. However, when passengers have a strong cooling demand, the internal circulation mode is used to cool down faster. Then, as the temperature rises, the mode gradually switches to external circulation.

[0067] Hot and cold air damper control: The opening of the mixing damper is also calculated in real time based on the water temperature and evaporator temperature. The opening of the mixing damper changes the mixing ratio of hot and cold air, thereby controlling the temperature of the blown-out air.

[0068] Mode damper control: Automatic switching of the air outlet mode is mainly calculated and controlled based on the required air outlet temperature. When the system is determined to be cooling the passenger compartment, the air outlet mode switches to blowing towards the face; for the intermediate environment, it switches to blowing towards the face and feet; when the system is determined to be heating, it switches to blowing towards the feet or blowing towards the feet for defrosting. In addition, light correction is also required to consider the impact of light on cooling and heating, and to increase the switching temperature for blowing towards the face and towards the feet.

[0069] In parking mode, the air conditioning system employs an intelligent ventilation strategy that monitors glass temperature, dew point temperature, and interior humidity. When the glass temperature minus the dew point temperature is less than a safe constant, the system adjusts the opening of the internal and external air circulation. The internal and external air circulation opening, the safe constant of glass temperature minus the dew point temperature, and the interior humidity are used for closed-loop feedback regulation to maintain the internal and external air circulation opening ratio and keep the safe constant of glass temperature minus the dew point temperature and interior humidity within the normal range of 45% to 65%. When the glass temperature minus the dew point temperature is greater than the safe constant, the system maintains the current state calculated by the intelligent mode.

[0070] In this embodiment, when the air conditioner is in ventilation mode in parking mode: the temperature damper is in the full cooling position, the compressor and PTC are off, the blower airflow is at level 2, the mode is in face blowing mode, and the internal and external circulation is in external circulation.

[0071] In the ventilation mode, the air conditioning interface can be manually operated. The blower air volume is operated according to the manual response level 1-7. The manual operation mode is operated according to the face blowing, foot blowing, face blowing and foot blowing, and foot defrosting. After the internal and external circulation damper responds to the manual operation and enters the internal circulation, it will maintain the internal circulation for a safe constant time. Then, the opening ratio of the internal and external circulation will be adjusted to adjust the safe constant air exchange volume. During the air exchange process, the icons of internal and external circulation remain unchanged.

[0072] In parking mode, the air conditioning system operates in ventilation mode, detecting glass temperature, dew point temperature, and interior humidity. When the glass temperature minus the dew point temperature is less than a safe constant, the opening of the internal and external air circulation is adjusted. The opening of the internal and external air circulation, the safe constant of glass temperature minus the dew point temperature, and the interior humidity are adjusted in a closed-loop feedback system to maintain the opening ratio of the internal and external air circulation and keep the safe constant of glass temperature minus the dew point temperature and interior humidity within the normal range.

[0073] When the parking air conditioner is in smart mode, if the indoor temperature is lower than the target air outlet temperature and the air outlet temperature is lower than the safe constant, the compressor should not be turned on.

[0074] like Figure 3 As shown, the logic for determining whether the parking air conditioner is turned on is as follows:

[0075] Battery level calculation and conditions for enabling / disabling parking air conditioning in EV parking mode:

[0076] When SOC is greater than or equal to the upper limit of the safety constant, the parking air conditioner is turned on.

[0077] When the lower limit of the safety constant is less than or equal to the upper limit of the safety constant, the air conditioner is turned on. As the battery level decreases, the air conditioner is turned off when the battery level drops to less than the lower limit of the safety constant minus the fixed constant.

[0078] When SOC is less than the lower limit of the safety constant, the parking air conditioner is turned off.

[0079] Battery level calculation and parking air conditioning deactivation conditions in EV parking mode:

[0080] When SOC is less than the lower limit of the safety constant, the parking air conditioner is deactivated.

[0081] HEV parking mode battery calculation and conditions for enabling / disabling parking air conditioning:

[0082] If the actual battery level minus the backup battery level is greater than or equal to the upper limit of the safety constant, turn on the parking air conditioner.

[0083] When the lower limit of safety constant is less than or equal to the actual power consumption minus the power reserve, and less than the upper limit of safety constant, the air conditioner is turned on. During the turning-on process, as the power consumption decreases to SOC less than the lower limit of safety constant minus the fixed constant, the air conditioner is turned off when parking.

[0084] If the actual battery level minus the backup battery level is less than the lower limit of the safety constant, the parking air conditioner will be turned off.

[0085] Battery level calculation and parking air conditioning deactivation conditions in EV parking mode:

[0086] If the actual battery level minus the backup battery level is less than the lower limit of the safety constant, the parking air conditioner will deactivate.

[0087] In this embodiment, the logic for the parking air conditioning activation button is as follows:

[0088] When the parking air conditioner is turned on, the settings for automatic, AC MAX, mode, synchronization, energy saving, comfort, powerful, front defrost, A / C, temperature, and internal / external circulation will not be remembered and restored after exiting the operation.

[0089] like Figure 4 As shown, this disclosure also proposes a parking air conditioning system for automobiles, the system comprising:

[0090] The acquisition module is used to acquire the vehicle status of the target vehicle at the current moment;

[0091] The judgment module is used to determine whether the target vehicle meets the prerequisites for entering the parking air conditioning based on the vehicle status of the target vehicle at the current moment.

[0092] The second determining module is used to determine the execution mode of the parking air conditioner of the target vehicle and activate the parking air conditioner if the target vehicle meets the preconditions.

[0093] Specifically, the system also includes:

[0094] The first determining module is used to acquire the temperature and humidity information of the target vehicle and determine the parking air conditioning usage time of the target vehicle.

[0095] The adjustment module is used to adjust the parking comfort of the target vehicle.

[0096] like Figure 5 As shown, corresponding to the above-described automotive parking air conditioning method, this disclosure also provides an electronic device. Since the embodiment of this device is similar to the above-described method embodiment, the description is relatively simple; relevant details can be found in the description of the above-described method embodiment section. The device described below is merely illustrative. This device may include: a processor 1, a memory 2, a communication bus (i.e., the aforementioned device bus), and a lookup engine. The processor 1 and memory 2 communicate with each other via the communication bus and communicate with external systems via a communication interface. The processor 1 can call logical instructions in the memory 2 to execute the automotive parking air conditioning method.

[0097] Furthermore, the logical instructions in the aforementioned memory 2 can be implemented as software functional units and sold or used as independent products, and can be stored in a computer-readable storage medium. Based on this understanding, the technical solution of this disclosure, in essence, or the part that contributes to the prior art, or a part of the technical solution, can be embodied in the form of a software product. This computer software product is stored in a storage medium and includes several instructions to cause a computer device (which may be a personal computer, server, or network device, etc.) to execute all or part of the steps of the methods described in the various embodiments of this disclosure. The aforementioned storage medium includes various media capable of storing program code, such as memory chips, USB flash drives, portable hard drives, read-only memory (ROM), random access memory (RAM), magnetic disks, or optical disks.

[0098] On the other hand, this disclosure also provides a processor-readable storage medium storing a computer program 3, which, when executed by a processor 1, is implemented to perform the parking air conditioning method for automobiles provided in the above embodiments.

[0099] The processor-readable storage medium can be any available medium or data storage device that the processor 1 can access, including but not limited to magnetic memory (e.g., floppy disk, hard disk, magnetic tape, magneto-optical disk (MO)), optical memory (e.g., CD, DVD, BD, HVD), and semiconductor memory (e.g., ROM, EPROM, EEPROM, non-volatile memory (NAND FLASH), solid-state drive (SSD)).

[0100] Those skilled in the art should understand that, despite the detailed description of this disclosure with reference to the foregoing embodiments, modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this disclosure.
