[0060] The following description, in conjunction with the accompanying drawings, illustrates exemplary embodiments of the present invention, including various details to aid understanding. These details should be considered merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the invention. Similarly, for clarity and brevity, descriptions of well-known functions and structures are omitted in the following description.

[0061] It should be noted that the collection, analysis, use, transmission, and storage of user personal information involved in the technical solution of this invention all comply with relevant laws and regulations, are used for legitimate and reasonable purposes, and are not shared, disclosed, or sold outside of these legitimate uses, and are subject to supervision and management by regulatory authorities. Necessary measures should be taken to prevent unauthorized access to such personal information data, ensure that personnel authorized to access personal information data comply with relevant laws and regulations, and ensure the security of user personal information.

[0062] Figure 1This is a flowchart of a vehicle air conditioning control method according to a first embodiment of the present invention. As one embodiment of the present invention, such as... Figure 1 As shown, the vehicle air conditioning control method may include:

[0063] Step S101: Determine whether the air conditioner is in recirculation mode and the cooling function is on, and whether the remaining time for the vehicle to reach its destination is less than or equal to the first time threshold.

[0064] In this step, the current circulation mode (e.g., internal or external circulation mode) and operating status (e.g., cooling or heating) of the air conditioner are obtained to determine whether the air conditioner is currently in internal circulation mode and the cooling function is on. Additionally, this step also obtains the remaining time for the vehicle to reach its destination to determine whether the remaining time is less than or equal to a first time threshold.

[0065] It should be noted that one can first determine whether the air conditioner is in recirculation mode and the cooling function is on, and then determine whether the remaining time for the vehicle to reach its destination is less than or equal to a first time threshold. Alternatively, one can first determine whether the remaining time for the vehicle to reach its destination is less than or equal to the first time threshold, and then determine whether the air conditioner is currently in recirculation mode and the cooling function is on. Or one can simultaneously determine whether the air conditioner is in recirculation mode and the cooling function is on, and whether the remaining time for the vehicle to reach its destination is less than or equal to the first time threshold. This embodiment of the invention does not impose any limitations on these aspects.

[0066] Optionally, the remaining time for the vehicle to reach its destination is the sum of the driving time to reach the destination and the parking time required for the vehicle to stop at the destination. In embodiments of the present invention, if the vehicle is traveling based on a navigation system, the driving time to the destination can be directly obtained from the navigation system; if the vehicle is not traveling based on a navigation system, the driving time to the destination can be predicted based on historical driving data, such as obtaining the driving time of the vehicle to the destination over a past period and calculating the average of these driving times as the predicted driving time to the destination. If the vehicle is not traveling based on a navigation system, the distance between the vehicle's current location and the destination can also be divided by the current vehicle speed to obtain the predicted driving time to the destination.

[0067] Optionally, the parking time required for the vehicle to stop at the destination is the difference between the time the vehicle is turned off after arriving at the destination and the time the vehicle was parked when it arrived at the destination. For example, when the vehicle arrives at the destination, the current time T1 is obtained (i.e., the parking time when the vehicle arrives at the destination), and when the vehicle is turned off, the current time T2 is obtained (i.e., the time the vehicle is turned off after arriving at the destination). T2-T1 is the parking time required for the vehicle to stop at the destination.

[0068] It should be noted that the time the vehicle shuts off after reaching its destination and the time it stops at the destination can be obtained from historical driving data. However, if there is no relevant data on the vehicle reaching its destination in the historical driving data (i.e., the vehicle is about to reach its destination for the first time), the parking time required for each stop can be calculated based on the historical driving data, and then the average of these parking times can be calculated as the parking time required for the vehicle to stop at the destination.

[0069] Step S102: In response to the air conditioner being in internal circulation mode and the cooling function being turned on, and the remaining time being less than or equal to the first time threshold, the air conditioner is controlled to switch from internal circulation mode to external circulation mode.

[0070] If the air conditioning is in recirculation mode and cooling is on, and the remaining time to reach the destination is less than or equal to a first time threshold, the air conditioning will switch from recirculation mode to external circulation mode. It should be noted that recirculation mode uses air from inside the vehicle for recirculation, while external circulation mode uses air from outside the vehicle for recirculation.

[0071] During the air conditioning cooling process, the cold air in the air ducts and evaporator generates moisture when heated. If the user gets out of the vehicle immediately after the engine is turned off, this moisture will remain in the air ducts and evaporator. This residual moisture can easily lead to mold growth and unpleasant odors. To solve this technical problem, this invention switches the air conditioning from internal circulation mode to external circulation mode before the vehicle reaches its destination. That is, the air conditioning stops cooling while the vehicle circulates outside air. This helps reduce the temperature difference between the air in the air ducts and evaporator and the outside air, thereby reducing moisture generation. Furthermore, the outside air can dry the moisture remaining in the air ducts and evaporator as much as possible, further reducing moisture levels. Therefore, this invention can effectively reduce the possibility of unpleasant odors from the air conditioning system.

[0072] In embodiments of the present invention, the first time threshold can be preset and can be obtained based on at least one of the following: the temperature difference between the inside and outside of the vehicle, the temperature recovery trend, and the humidity outside the vehicle. For example, the larger the temperature difference between the inside and outside of the vehicle, the larger the first time threshold; the smaller the temperature difference, the smaller the first time threshold; the larger the temperature recovery trend, the larger the first time threshold; the smaller the temperature recovery trend, the smaller the first time threshold; the larger the humidity outside the vehicle, the larger the first time threshold; and the smaller the humidity outside the vehicle, the smaller the first time threshold.

[0073] Figure 2 This is a flowchart of a vehicle air conditioning control method according to a second embodiment of the present invention. As another embodiment of the present invention, such as... Figure 2 As shown, the vehicle air conditioning control method may include:

[0074] Step S201: Determine whether the remaining time for the vehicle to reach its destination is less than or equal to the first time threshold; if yes, proceed to step S202; otherwise, end the process.

[0075] Step S202: Determine whether the air conditioner is in recirculation mode and the cooling function is on; if yes, proceed to step S203; otherwise, end.

[0076] Step S203: Send a notification to the user whether to enter the outer loop mode.

[0077] Step S204: Determine whether a confirmation result for entering the outer loop mode submitted by the user has been received; if yes, proceed to step S205; otherwise, end.

[0078] Step S205: Control the air conditioner to switch from internal circulation mode to external circulation mode.

[0079] In this embodiment, it is first determined whether the remaining time for the vehicle to reach its destination is less than or equal to a first time threshold. If the remaining time is less than or equal to the first time threshold, it is then determined whether the air conditioner is in recirculation mode and the cooling function is on. If the air conditioner is in recirculation mode and the cooling function is on, a notification is sent to the user asking whether to enter external circulation mode. In other embodiments, it is also possible to first determine whether the air conditioner is in recirculation mode and the cooling function is on. If the air conditioner is in recirculation mode and the cooling function is on, it is then determined whether the remaining time for the vehicle to reach its destination is less than or equal to a first time threshold. If the remaining time is less than or equal to the first time threshold, a notification is sent to the user asking whether to enter external circulation mode.

[0080] In this embodiment, after notifying the user whether to enter the external circulation mode, the system monitors the user's actions in real time. If the system receives confirmation from the user that they want to enter the external circulation mode, it controls the air conditioner to switch from the internal circulation mode to the external circulation mode. This allows the system to enter the external circulation mode according to the user's actual needs, which helps to improve the user experience.

[0081] Optionally, step S205 may include: acquiring the vehicle's external environment information and determining whether the external environment information meets the external circulation start-up conditions; in response to the external environment information not meeting the external circulation start-up conditions, controlling the air conditioner to continue in internal circulation mode and with the cooling function on; in response to the external environment information meeting the external circulation start-up conditions, controlling the air conditioner to switch from internal circulation mode to external circulation mode; wherein, the external environment information includes at least one of the following: air quality, air humidity, traffic volume, vehicle speed, and the vehicle's location information. In step S205, the vehicle's external environment information is acquired at regular intervals, and it is determined whether the external environment information meets the external circulation start-up conditions. If it does, it indicates that the current external environment information is suitable for external circulation mode, and the air conditioner is controlled to switch from internal circulation mode to external circulation mode; if it does not, it indicates that the current external environment information is not suitable for external circulation mode, and the air conditioner is controlled to continue in internal circulation mode and with the cooling function on. For example, if the outside air quality is poor, the outside air humidity is high, the traffic volume is heavy, the surrounding vehicles are moving slowly, or the vehicle has driven through water, or there is a garbage dump or construction site nearby, these external environmental conditions do not meet the conditions for starting the external air circulation. Therefore, the air conditioner is kept in internal circulation mode and the cooling function is turned on to avoid blowing outside air into the vehicle and causing discomfort to the occupants.

[0082] Optionally, the external environment information can be obtained directly from the server or collected by sensors installed on the vehicle, such as air quality detectors, humidity sensors, and cameras.

[0083] Figure 3 This is a flowchart of a vehicle air conditioning control method according to a third embodiment of the present invention. As another embodiment of the present invention, such as... Figure 3 As shown, the vehicle air conditioning control method may include:

[0084] Step S301: Determine whether the remaining time for the vehicle to reach its destination is less than or equal to the first time threshold; if yes, proceed to step S302; otherwise, end.

[0085] Step S302: Determine whether the air conditioner is in recirculation mode and the cooling function is on; if yes, proceed to step S303; otherwise, end.

[0086] Step S303: Obtain the external environment information of the vehicle. The external environment information includes at least one of the following: air quality, air humidity, traffic volume, vehicle speed, and the vehicle's location information.

[0087] Step S304: Determine whether the external environment information meets the external loop start conditions; if yes, proceed to step S305; if no, end.

[0088] In this embodiment, it is first determined whether the remaining time for the vehicle to reach its destination is less than or equal to a first time threshold. If the remaining time is less than or equal to the first time threshold, it is then determined whether the air conditioning is in recirculation mode. If the air conditioning is in recirculation mode, the vehicle's external environmental information is obtained. In other embodiments, it is also possible to first determine whether the air conditioning is in recirculation mode. If the air conditioning is in recirculation mode, it is then determined whether the remaining time for the vehicle to reach its destination is less than or equal to a first time threshold. If the remaining time is less than or equal to the first time threshold, the vehicle's external environmental information is obtained. Optionally, the external environmental information can be obtained directly from the server or collected by sensors installed on the vehicle, such as air quality detectors, humidity sensors, and cameras.

[0089] In this embodiment, before switching the air conditioner from recirculation mode to external circulation mode, it first determines whether the external environmental information meets the external circulation activation conditions. If it does, the air conditioner switches from recirculation mode to external circulation mode. If it does not meet the conditions, it means that the current external environmental information is not suitable for external circulation mode, and the process ends, meaning the air conditioner continues to be in recirculation mode. This avoids blowing outside air into the vehicle and causing discomfort to the occupants.

[0090] For example, if the outside air quality is poor, the outside air humidity is high, the traffic volume is high, the surrounding vehicles are moving slowly, or the vehicle has driven through water, or there is a garbage dump or construction site nearby, these external environmental conditions do not meet the conditions for starting the external circulation mode, so the air conditioner will continue to be in internal circulation mode.

[0091] Step S305: Control the air conditioner to switch from internal circulation mode to external circulation mode.

[0092] Optionally, step S305 may include: acquiring the vehicle's external environment information and determining whether the external environment information meets the external circulation start-up conditions; in response to the external environment information not meeting the external circulation start-up conditions, controlling the air conditioner to continue in internal circulation mode and with the cooling function on; in response to the external environment information meeting the external circulation start-up conditions, controlling the air conditioner to switch from internal circulation mode to external circulation mode. In step S35, the vehicle's external environment information is acquired at regular intervals, and it is determined whether the external environment information meets the external circulation start-up conditions. If it does not meet the conditions, it indicates that the current external environment information is not suitable for external circulation mode, and the air conditioner is controlled to continue in internal circulation mode and with the cooling function on.

[0093] Figure 4 This is a flowchart of a vehicle air conditioning control method according to a fourth embodiment of the present invention. As another embodiment of the present invention, such as... Figure 4 As shown, the vehicle air conditioning control method may include:

[0094] Step S401: Determine whether the remaining time for the vehicle to reach its destination is less than or equal to the first time threshold; if yes, proceed to step S402; otherwise, end.

[0095] Step S402: Determine whether the air conditioner is in recirculation mode and the cooling function is on; if yes, proceed to step S403; otherwise, end.

[0096] Step S403: Obtain the external environment information of the vehicle.

[0097] Step S404: Determine whether the external environment information meets the external loop start conditions; if yes, proceed to step S405; otherwise, end.

[0098] Step S405: Send a notification to the user whether to enter the outer loop mode.

[0099] Step S406: Determine whether a confirmation result for entering the outer loop mode submitted by the user has been received; if yes, proceed to step S407; otherwise, end.

[0100] Step S407: Control the interior temperature of the vehicle to be below the temperature threshold.

[0101] Step S408: Determine whether the duration of the vehicle interior temperature being lower than the temperature threshold is greater than or equal to the second time threshold; if yes, proceed to step S409; if no, proceed to step S407.

[0102] Step S409: Control the air conditioner to switch from internal circulation mode to external circulation mode, and control the air conditioner to turn off its cooling function.

[0103] In this embodiment, the system first determines whether the external environmental information meets the conditions for starting the external air circulation mode. If it does, a notification is sent to the user asking whether to enter the external air circulation mode. If the user confirms entering the external air circulation mode, the air conditioner continues to cool and appropriately increases the airflow to lower the interior temperature below a temperature threshold. Next, it determines whether the duration of the interior temperature being below the temperature threshold is greater than or equal to a second time threshold. If so, the air conditioner switches from internal circulation mode to external air circulation mode and shuts off its cooling function. If not, the air conditioner continues to cool until the duration of the interior temperature being below the temperature threshold is greater than or equal to the second time threshold, at which point it switches back to external air circulation mode and shuts off its cooling function. This increases the comfort of the occupants.

[0104] It should be noted that the temperature threshold can be pre-configured, such as 23℃, 25℃, or 26℃, or it can be calculated based on the target temperature corresponding to the cooling function set by the user. For example, the temperature threshold is equal to the target temperature set by the user minus the buffer temperature, where the buffer temperature can be pre-configured, such as set to 1℃, 2℃, or 3℃, so that the temperature inside the vehicle is lower than the target temperature set by the user, which helps to improve the comfort of the occupants.

[0105] Optionally, after step S409, the method further includes: adjusting the airflow of the air conditioner to the maximum. In an embodiment of the present invention, after controlling the air conditioner to switch from internal circulation mode to external circulation mode, the airflow of the air conditioner can be further adjusted to the maximum. This can raise the temperature of the air in the air duct and evaporator to the same as the outside air temperature in the shortest possible time, and at the same time, it can quickly dry the moisture remaining in the air duct and evaporator, thereby minimizing the possibility of odors from the air conditioning system.

Optionally, the vehicle system architecture 600 may include more or fewer systems, and each system may include multiple components. Furthermore, each system and component of the vehicle system architecture 600 may be interconnected via wired or wireless means.

[0128] The vehicle system architecture 600 includes an autonomous driving system 601, which can be in a fully or partially autonomous driving mode. For example, the autonomous driving system 601 can automatically control the vehicle's movement without human interaction; the autonomous driving system 601 can also control the vehicle's autonomous driving while in autonomous driving mode, and can also adjust its autonomous driving behavior through human interaction.

[0129] The powertrain 602 may include components that provide power to the vehicle. For example, the powertrain 602 may include an engine, an energy source, a transmission, wheels, tires, etc. The engine may be an internal combustion engine, an electric motor, an air-compressed engine, or other combinations of engines, such as a hybrid engine consisting of a gasoline engine and an electric motor, or a hybrid engine consisting of an internal combustion engine and an air-compressed engine. The engine converts the energy source into mechanical energy to supply the transmission. Examples of energy sources may include gasoline, diesel, other petroleum-based fuels, propane, other compressed gas-based fuels, ethanol, solar panels, batteries, and other electrical sources. The energy source may also provide energy to other systems in the vehicle. Furthermore, the transmission may include a gearbox, a differential, a drive shaft, and a clutch, etc.

[0130] Sensor system 603 may include sensors for sensing the vehicle's surrounding environment. Examples include a positioning system (which may be a Global Positioning System (GPS), BeiDou Navigation Satellite System, or other positioning systems), radar, a laser rangefinder, an inertial measurement unit (IMU), and a camera. The positioning system can be used to determine the vehicle's geographical location. The IMU is used to sense changes in the vehicle's position and orientation based on inertial acceleration. In one embodiment, the IMU may be a combination of an accelerometer and a gyroscope. The radar can use radio signals to sense objects in the vehicle's surrounding environment. In some embodiments, in addition to sensing objects, the radar can also be used to sense the speed and / or direction of travel of objects.

[0131] To detect environmental information and objects located in front of, behind, or to the sides of the vehicle, radar, cameras, and other devices can be configured at appropriate locations on the exterior of the vehicle. For example, to acquire an image of the front of the vehicle, a camera can be configured inside the vehicle and close to the windshield. Alternatively, the camera can be configured around the front bumper or radiator grille. Similarly, to acquire an image of the rear of the vehicle, a camera can be configured inside the vehicle and close to the rear window. Alternatively, the camera can be configured around the rear bumper, trunk, or tailgate. To acquire images of the sides of the vehicle, a camera can be configured inside the vehicle and close to at least one of the side windows. Alternatively, the camera can be configured around the side mirrors, fenders, or doors.

[0132] Laser rangefinders use lasers to sense objects in the environment in which a vehicle is located.

[0133] A camera can be used to capture multiple images of the vehicle's surroundings. The camera can be a still camera or a video camera.

[0134] The control system 604 may include software systems for implementing autonomous driving, such as a route planning system, an obstacle avoidance system, and a vision system for image analysis. The control system 604 may also include hardware systems such as an accelerator and steering wheel system. Furthermore, the control system 604 may add or replace components other than those shown and described. Alternatively, some of the components shown above may be omitted.

[0135] The control system 604 interacts with external sensors, other autonomous driving devices, other computer systems, or users via peripheral devices 605. Peripheral devices 605 may include wireless communication systems, on-board computers, microphones, and / or speakers.

[0136] In some embodiments, peripheral device 605 provides a means for user interaction with the control system 604 via a user interface. For example, an onboard computer may provide information to a user of the vehicle. The user interface may also operate the onboard computer to receive user input. The onboard computer may be operated via a touchscreen. In other cases, peripheral device may provide a means for communicating with other devices located within the vehicle. For example, a microphone may receive audio (e.g., voice commands or other audio input) from a user of the control system 604. Similarly, a speaker may output audio to a user of the control system 604.

[0137] Wireless communication systems can communicate wirelessly with one or more devices, either directly or via a communication network. For example, wireless communication systems can use networks such as cellular networks, WiFi, and wireless local area networks (WLANs), or they can use infrared links, Bluetooth, or ZigBee to communicate directly with devices. Other wireless protocols include those used in various autonomous driving communication systems.

[0138] The power source 606 can provide power to various components of the vehicle. The power source 606 can be a rechargeable lithium-ion or lead-acid battery.

[0139] The computer system 607 controls some or all of the functions enabling autonomous driving. The computer system 607 may include at least one processor that executes instructions stored in a non-transitory computer-readable medium such as memory. The computer system 607 provides the execution code for the aforementioned autonomous driving system to implement autonomous driving.

[0140] The processor can be any conventional processor, such as a commercially available central processing unit (CPU). Alternatively, the processor can be a dedicated device such as an application-specific integrated circuit (ASIC) or other hardware-based processor. Those skilled in the art will understand that the processor, computer, or memory can actually include multiple processors, computers, or memories that may or may not be stored in the same physical housing. For example, memory can be a hard disk drive or other storage media located in a housing different from that of a computer. Therefore, references to processors or computers will be understood to include references to a collection of processors or computers or memories that may or may not operate in parallel. Unlike using a single processor to perform the steps described herein, some components, such as steering and deceleration components, may each have their own processor that performs calculations only related to the component's specific function.

[0141] User interface 608 is used to provide information to or receive information from users of the vehicle. Optionally, user interface 608 may include one or more input / output devices within a set of peripheral devices 605, such as wireless communication systems, on-board computers, microphones, and speakers.

[0142] It should be understood that the components described above are merely an example. In actual applications, components in the various modules or systems mentioned above may be added or removed as needed. Figure 6 This should not be construed as a limitation on the embodiments of this application.

[0143] This invention also provides a computer-readable medium having a computer program stored thereon, which, when executed by a processor, implements the methods described in any of the above embodiments.

[0144] The specific embodiments described above do not constitute a limitation on the scope of protection of this invention. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can occur depending on design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this invention should be included within the scope of protection of this invention.
