[0020] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0021] The disclosure below provides many different embodiments or examples for implementing the present invention. In order to simplify the disclosure of the present invention, the components and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplicity and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present invention provides various specific processes and examples of materials, but those of ordinary skill in the art can appreciate the applicability of other processes and / or the use of other materials.

[0022] The following describes a vehicle air conditioning control method according to an embodiment of the present invention with reference to the accompanying drawings.

[0023] like Figures 1 to 4As shown, according to an embodiment of the present invention, the vehicle air conditioning control method includes: after the vehicle is powered off, the vehicle's required intelligent air conditioning mode is determined according to the vehicle's environmental information and the vehicle's parking time. Wherein, when the vehicle is powered off, the vehicle's air conditioning system cannot continue to work after the power is cut off, but is affected by the vehicle's external environment. For example, in winter, the external environment temperature is low. As the vehicle is parked for a longer time, the temperature in the cabin gradually decreases. At this time, in order to ensure that the cabin can be restored to a comfortable temperature for the user, it is necessary to heat the cabin, that is, the air conditioning system needs to enter the heating mode; such as in summer, the external environment temperature is high. As the vehicle is parked for a longer time, the temperature in the cabin gradually increases. At this time, in order to ensure that the cabin can be restored to a comfortable temperature for the user, it is necessary to cool the cabin, that is, the air conditioning system needs to enter the cooling mode. In addition, in addition to the conventional cooling and heating functions, the vehicle's air conditioning system also has ventilation, defrosting and defogging functions. For example, when the temperature difference between the inside and outside of the vehicle reaches a certain value, the vehicle glass is prone to fogging and frosting. At this time, the air conditioning system needs to enter the defog / defrost mode, such as blowing air to the front windshield. By using the environmental information of the vehicle's parking location and the parking time of the vehicle, the required working mode of the air-conditioning system can be determined more accurately, eliminating the step of users judging and controlling the mode of the air-conditioning system according to the vehicle conditions, thereby simplifying the user's vehicle operation.

[0024] After the vehicle is powered on, the user is prompted whether to turn on the smart air conditioning mode. That is to say, when the vehicle is restarted after parking, when it is determined that the air conditioning system needs to intervene to improve the cabin environment or defrost or defog, the above information will be notified to the user, so that the user can accurately know the operation of the smart air conditioning mode, and at the same time realize the controllability of the smart air conditioning mode. The user only needs to confirm whether to enter the smart air conditioning mode, which saves the user from controlling the air conditioning system to switch between different modes and adjust the temperature. The degree of intelligence is high.

[0025] The user confirms to turn on the smart air conditioning mode and determines whether the vehicle is in a parking state. The parking state refers to the vehicle being stationary for a long time. Short-term braking and parking actions do not belong to the parking state. In other words, after the user confirms to turn on the smart air conditioning mode, it will determine whether the vehicle has the conditions to enter a long-term parking state.

[0026] When the vehicle is in the parking state, the air conditioning system is controlled to enter the intelligent air conditioning mode, and the power supply of all electrical devices in the vehicle except the air conditioning system is cut off. In other words, the air conditioning system can only enter the intelligent air conditioning mode after the vehicle is in the parking state, and at this time only the air conditioning system is powered, and the power supply of other electrical devices is cut off, such as daytime running lights, ambient lights and other electrical devices not related to the air conditioning system. Therefore, the overall energy consumption of the vehicle after entering the intelligent air conditioning mode can be reduced, and the safety of the vehicle can be better guaranteed when it is in the parking state.

[0027] After exiting the intelligent air conditioning mode, the power supply to the vehicle's electrical equipment is restored to ensure normal driving of the vehicle.

[0028] According to the vehicle air-conditioning control method of an embodiment of the present invention, the required working mode of the air-conditioning system can be determined more accurately through the environmental information of the vehicle parking location and the parking time of the vehicle, thereby eliminating the step of the user judging and controlling the mode of the air-conditioning system according to the vehicle condition, thereby simplifying the user's vehicle operation. In addition, after the air-conditioning system enters the intelligent air-conditioning mode, only the air-conditioning system is powered, which can reduce the overall energy consumption of the vehicle after entering the intelligent air-conditioning mode, and the safety of the vehicle can be better guaranteed when the vehicle is in the parking state.

[0029] According to some embodiments of the present invention, the environmental information of the vehicle includes at least the real-time geographic location of the vehicle, the weather information of the real-time geographic location, and the temperature and humidity inside and outside the vehicle. Among them, the real-time geographic location of the vehicle includes the latitude and longitude of the parking position of the vehicle and the altitude information, and the weather information may include information such as cloud cover, precipitation, temperature, humidity, wind direction and wind speed. The temperature and humidity inside and outside the vehicle can be obtained by corresponding sensors to more accurately obtain the temperature and humidity of the internal space and the external space of the vehicle. It can be understood that the longitude and latitude are convenient for locating the accurate parking position of the vehicle, so as to obtain the weather conditions of the current location. In addition, different altitudes and different air pressures have different effects on frost or fog. The actual temperature and humidity of the internal and external spaces of the vehicle can better correct the deviation in the weather information. For example, if the humidity of the external space is high and the temperature is low, it is easier to frost on the outer wall surface of the vehicle glass. Therefore, by simultaneously referring to the real-time geographic location of the vehicle, the weather information of the real-time geographic location, and the temperature and humidity inside and outside the vehicle to determine the intelligent air-conditioning mode required by the vehicle, the accuracy of the judgment can be improved.

[0030] According to some embodiments of the present invention, the intelligent air conditioning mode includes at least a defrost / defog mode, a cooling mode, and a heating mode. Therefore, when it is determined that there is a risk of frost or fogging on the glass of the vehicle, the intelligent air conditioning mode can enter the defrost / defog mode to blow air to the front windshield for defrosting or defog; when it is determined that the temperature in the vehicle is lower than the comfortable riding temperature, the intelligent air conditioning mode can enter the heating mode to heat the cabin space; when it is determined that the temperature in the vehicle is higher than the comfortable riding temperature, the intelligent air conditioning mode can enter the cooling mode to cool the cabin space. As a result, the intelligent air conditioning mode can be flexibly applied to different scenarios, with a high level of intelligence.

[0031] In some embodiments, when entering the smart air-conditioning mode, the air-conditioning system operates at maximum power to ensure defrosting / defogging, heating or cooling efficiency.

[0032] According to some embodiments of the present invention, after the vehicle is powered on, prompting the user whether to turn on the smart air conditioning mode includes: displaying a smart air conditioning mode turn-on button on the touch display screen. Therefore, the turn-on button of the smart air conditioning mode is a virtual button formed on the touch display screen, which saves the space occupied by the turn-on button. The user can confirm to enter the smart air conditioning mode by clicking the turn-on button on the touch display screen, which is more eye-catching and easy to operate.

[0033] According to some embodiments of the present invention, after the vehicle is powered on, prompting the user whether to turn on the smart air conditioning mode includes: highlighting the physical button corresponding to the smart air conditioning mode. In other words, the on button for the smart air conditioning mode is a physical button, and the user confirms entering the smart air conditioning mode by pressing the physical button. The interaction accuracy of the physical button is good, and accidental touches can be avoided.

[0034] According to some embodiments of the present invention, after the vehicle is powered on, prompting the user whether to turn on the smart air conditioning mode includes: announcing whether to turn on the smart air conditioning mode through voice. That is, when the conditions for entering the smart air conditioning mode are met, the above information can be played through the speaker in the vehicle, which can inform the user more directly and accurately, and the user can turn on the smart air conditioning mode through voice interaction, such as saying a voice recognition command of "confirm to turn on".

[0035] It should be noted that the on button of the smart air-conditioning mode may be displayed on the touch screen while the smart air-conditioning mode also has a corresponding physical button; the on button of the smart air-conditioning mode may be displayed on the touch screen while voice announcement is made; the smart air-conditioning mode may have a corresponding physical button while voice announcement is made; the on button of the smart air-conditioning mode may be displayed on the touch screen while the smart air-conditioning mode also has a corresponding physical button and voice announcement is made, etc. There is no specific limitation here.

[0036] According to some embodiments of the present invention, determining whether the vehicle is in a parking state includes: determining whether the vehicle is in a stationary state; when the vehicle is in a stationary state, determining whether the caliper is in a clamped state; when the caliper is in a clamped state, determining whether the vehicle gear is in P gear; when the vehicle is in a stationary state, the caliper is in a clamped state and the vehicle gear is in P gear, determining that the vehicle is in a parking state.

[0037] That is to say, only when the vehicle is stationary, the caliper clamps the brake disc and the vehicle gear is in P gear, it indicates that the vehicle enters the parking state. It is understandable that when the vehicle is stationary, if the caliper is not in a clamped state or the vehicle is not in P gear, the vehicle may still move at this time, and when the caliper is clamped, the vehicle may be in the process of deceleration, which does not mean that the vehicle is completely stationary, and when waiting for a red light, stepping on the brake is only a short-term parking operation, and only engaging the P gear, there are also models where the caliper of the vehicle engaged in P gear is in a loose state. Therefore, by judging that the vehicle is stationary, the caliper is clamped and the vehicle is in P gear, it is ensured that the vehicle can enter a longer parking state to ensure the safety of the vehicle.

[0038] According to some embodiments of the present invention, the determination of whether the vehicle is stationary includes: obtaining a vehicle speed signal and a wheel speed; when the vehicle speed and the wheel speed are zero, determining that the vehicle is stationary. Thus, the accuracy of confirming that the vehicle is stationary can be improved. In a specific example, the wheel speed of each wheel is obtained, and when the wheel speed of each wheel is zero and the vehicle speed is zero, it is determined that the vehicle is stationary.

[0039] According to some embodiments of the present invention, after the user confirms to enter the smart air conditioning mode, if the vehicle is not in the parking state, the user is prompted to control the vehicle to the parking state and try again. In this way, the user can accurately know the reason why the smart air conditioning mode cannot be entered, so that the user can operate the air conditioning system to smoothly enter the smart air conditioning mode.

[0040] According to some embodiments of the present invention, the prompting the user to control the vehicle to the parking state and try again includes: when the vehicle is not in a stationary state, prompting the user to try after stopping; when the caliper is not in a clamped state, prompting the user to pull up the handbrake and try; when the vehicle gear is not in P gear, prompting the user to switch to P gear and try. In other words, the user can be accurately informed of the reason why the vehicle has not entered the parking state, so that the user can perform corresponding operations according to the corresponding prompts. For example, when it is prompted that the vehicle is not in a stationary state, the user can stop the vehicle, and after stopping the vehicle, the prompt disappears; when it is prompted that the caliper of the vehicle is not in a clamped state, the user can clamp the caliper by pulling the handbrake, etc., and then the prompt disappears; when it is prompted that the vehicle is not in P gear, the user can switch to P gear through the gear shifting device, and after entering P gear, the prompt disappears. In this way, it can be ensured that the vehicle can enter the parking state more quickly, so as to facilitate the execution of the subsequent intelligent air-conditioning mode.

[0041] According to some embodiments of the present invention, after the air conditioning system is controlled to enter the intelligent air conditioning mode, the intelligent air conditioning mode is exited after detecting that the vehicle is out of the parking state, and the user is prompted to have exited the intelligent air conditioning mode. Therefore, after the vehicle is running, exiting the intelligent air conditioning mode can restore the normal power supply of the vehicle's electrical equipment to ensure the safety of the vehicle's driving. In some embodiments, when the vehicle speed is not zero, the user is prompted to exit the intelligent air conditioning mode because the vehicle speed is not zero; when the caliper of the vehicle is not clamped, the user is prompted to exit the intelligent air conditioning mode because the caliper is not clamped; when the vehicle gear is not in P gear, the user is prompted to exit the intelligent air conditioning mode because the P gear is not engaged. Therefore, the user can be accurately informed of the reason for exiting the intelligent air conditioning mode, so that the user can perform corresponding processing.

[0042] According to some embodiments of the present invention, after the air conditioning system is controlled to enter the intelligent air conditioning mode, the user confirms to exit the intelligent air conditioning mode by interacting with the button for releasing the intelligent air conditioning mode. In other words, the user can independently choose to interrupt the intelligent air conditioning mode by pressing the button for releasing the intelligent air conditioning mode, so as to ensure the controllability of the intelligent air conditioning mode.

[0043] In a specific example, after exiting the smart air-conditioning mode, the air-conditioning system enters the AUTO mode to reduce user operations.

[0044] According to some embodiments of the present invention, after entering the intelligent air conditioning mode, the vehicle windows and sunroof are closed. By closing the windows and sunroof, the cabin can be formed into a relatively closed space to reduce the impact of the external environment on the temperature regulation in the cabin, so as to ensure the cooling or heating efficiency in the intelligent air conditioning mode.

[0045] According to some embodiments of the present invention, when the intelligent air conditioning mode is the cooling mode, after entering the intelligent air conditioning mode, the internal circulation is turned on and the canopy is closed. Therefore, by turning on the internal circulation, it is possible to prevent the high-temperature air from the external environment from entering the cabin and causing the cabin temperature to rise. In addition, by closing the canopy, in the case of high sunlight intensity such as in summer, it is possible to prevent the cabin from being heated up quickly due to direct sunlight, thereby improving the cooling efficiency of the cabin in the intelligent air conditioning mode.
