[0067] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them.

Based on the embodiments of this disclosure, every other embodiment obtained by those skilled in the art without inventive effort falls within the scope of protection of this disclosure.

[0068] Research has found that as cars become increasingly intelligent, people's demands for convenience are also rising. Current car air conditioning systems typically require the driver or passenger to manually adjust the control panel to set the air conditioning zones, on / off status, temperature, fan speed, recirculation mode, and airflow mode. However, in situations where the driver is riding alone, manually controlling the air conditioning system via the control panel is inconvenient and may even pose a safety risk.

[0069] Based on this, the present disclosure provides a method for controlling an automotive air conditioner, so as to achieve convenient control of the in-vehicle air conditioner through user voice, avoiding driving safety risks caused by manual adjustment.

[0070] Please refer to Figures 1 and 2. Figure 1 is a flowchart of a control method for an automotive air conditioner according to an optional embodiment of this disclosure. Figure 2 is a schematic diagram of a control method for an automotive air conditioner according to an optional embodiment of this disclosure. This control method is applied to an automotive air conditioning control system, which includes: a voice interaction device, an infotainment system, a central processing module, and a zone controller.

[0071] As shown in Figure 2, in one optional implementation, the voice interaction device can be a device with audio acquisition and playback functions, such as a microphone. The voice interaction device is connected to the infotainment system (Infotainment Headquarters) and can be integrated into the Infotainment Headquarters. The Infotainment Headquarters is an in-vehicle integrated information processing system based on the vehicle bus system and Internet services. The Infotainment Headquarters includes a display, button panel, etc. Various applications, such as music and navigation, run on the Infotainment Headquarters. A user interface can be provided through the display screen, through which information can be displayed to the user and information input by the user can be received. The Infotainment Headquarters is connected to the central computing module, and the central computing module is connected to the regional controllers. The vehicle in this embodiment adopts an electronic and electrical architecture of central computing module + regional controllers, where the central computing module is responsible for the overall vehicle logic calculation and issues control commands to each regional controller, which is divided by factors such as function and location. Each regional controller controls the underlying actuators to perform corresponding actions according to the control commands.

[0072] The control method provided in this disclosure is applicable to various vehicle types, including gasoline vehicles, hybrid electric vehicles, and pure electric vehicles. As shown in Figure 1, the control method specifically includes:

[0073] S101. The voice interaction device collects the user's voice and sends the voice to the entertainment information host.

[0074] Here, after the air conditioning voice control function is turned on, the voice interaction device can continuously collect the voice in the car and send the collected voice to the entertainment information host.

[0075] S102. The entertainment information host generates an air conditioning control command based on the voice and sends the air conditioning control command to the central computing module.

[0076] In this step, the entertainment information host can recognize voice information from the voice, then generate air conditioning control commands based on the voice information, and send the air conditioning control commands to the corresponding domain controller of the air conditioner.

[0077] In one optional implementation, the entertainment information host is equipped with a voice control application; the voice control application includes a voice recognition and processing module and a format conversion module. Then step S102 may include:

[0078] S1021. The voice recognition and processing module verifies the voice; if the voice passes the verification, the verified voice is converted into the air conditioning control command and sent to the format conversion module.

[0079] In one optional implementation, the speech recognition and processing module can verify the speech in the following way:

[0080] The speech recognition and processing module identifies speech information from the speech, generates a confirmation speech based on the speech information, and sends the confirmation speech to the speech interaction device; the speech interaction device plays the confirmation speech to confirm with the user whether the speech information is correct; the speech interaction device collects the user's reply speech and sends the reply speech to the speech recognition and processing module; if the speech recognition and processing module identifies reply speech information indicating confirmation from the reply speech, it determines that the speech has passed the verification.

[0081] Here, voice information can indicate the user's intention to control the air conditioner. Voice information can be identified from the speech using natural language processing techniques such as keyword search and semantic similarity matching. A confirmation voice message is then generated based on this information and returned to the voice interaction device. Optionally, the entertainment information host pre-stores mapping relationships between different keywords and confirmation voice messages. After identifying keywords in the voice information, the corresponding confirmation voice message can be retrieved. For example, after identifying keywords including "air conditioner" and "on," the confirmation voice message "Do you want to turn on the air conditioner?" is generated.

[0082] Next, the voice interaction device plays a confirmation voice message, collects the user's response voice message, and sends the response voice message to the voice recognition and processing module. If the voice recognition and processing module recognizes a response voice message indicating confirmation, such as "yes" or "correct," then the voice message has passed verification.

[0083] In this way, by verifying the user's voice, errors in voice recognition can be avoided, which could lead to incorrect control of the air conditioner and require the user to manually adjust it. This helps improve the accuracy of voice control of the air conditioner and further reduces driving risks.

[0084] Next, the air conditioning control commands are converted from the voice information in the verified voice recordings and sent to the format conversion module. Optionally, the entertainment information host pre-stores the mapping relationship between different keywords and air conditioning control commands. After recognizing the keywords in the voice information, the corresponding air conditioning control commands can be retrieved.

[0085] S1022, The format conversion module converts the format of the air conditioning control command and sends the converted air conditioning control command to the central processing module.

[0086] Here, the format conversion module converts the air conditioning control commands into a protocol format compatible with the central processing module, and sends them to the central processing module via the vehicle network bus through the infotainment system's external interface. Optionally, the air conditioning control commands output by the format conversion module are in Ethernet format and are sent to the central processing module via Ethernet through the infotainment system's external interface.

[0087] Furthermore, while transmitting air conditioning control commands, the entertainment information host activates the screen and controls the display of the air conditioning control interface. The air conditioning control interface can display the air conditioning operating status, such as temperature, fan speed, and air supply mode. The air conditioning control interface has multiple controls that users can manually operate. The controls respond to the user's manual operation to adjust the air conditioning operating status, such as raising the temperature, lowering the fan speed, or changing the air supply mode.

[0088] Furthermore, before the speech recognition and processing module verifies the speech, step S102 may further include: waking up the voice control application by collecting the user's speech. Optionally, if a pre-set wake-up keyword can be recognized from the speech, the voice control application can be woken up to execute subsequent steps.

[0089] S103. The central processing module determines whether the vehicle meets the air conditioning control conditions based on the instruction type of the air conditioning control instruction; if it does, the air conditioning control instruction is sent to the area controller.

[0090] In one optional implementation, the instruction types include air conditioner shutdown instructions, air conditioner startup instructions, and air conditioner operation status adjustment instructions. The air conditioner operation status adjustment instructions include at least one of the following: air conditioner control zone, air conditioner temperature, fan speed, circulation mode, and blowing mode.

[0091] If the air conditioning control command is an air conditioning off command, it can be directly determined that the vehicle meets the air conditioning control conditions, and then the air conditioning off command is sent to the area controller. If the air conditioning control command is an air conditioning on command or an air conditioning operation status adjustment command, it is determined whether the vehicle meets the air conditioning control conditions based on the vehicle status signal, and if the air conditioning control conditions are met, the air conditioning control command is sent to the area controller, that is, it is allowed to control the vehicle's air conditioning accordingly.

[0092] In one optional implementation, if the air conditioning control command is an air conditioning start command, then whether the vehicle meets the air conditioning control conditions can be determined based on the vehicle's remaining battery power signal and / or remaining fuel level signal. Specifically, the remaining battery power signal and / or remaining fuel level signal are compared with a preset energy safety threshold. If the remaining battery power signal and / or remaining fuel level signal indicates that the vehicle's remaining fuel level and / or remaining battery power is higher than the preset energy safety threshold, then the vehicle meets the air conditioning control conditions; if the remaining battery power signal and / or remaining fuel level signal indicates that the vehicle's remaining fuel level and / or remaining battery power is not higher than the preset energy safety threshold, then the vehicle does not meet the air conditioning control conditions.

[0093] In another optional implementation, if the air conditioning control command is an air conditioning operation status adjustment command, the desired air conditioning operation status can be determined by logical operations based on the current operation status signal of the air conditioning in the vehicle and the air conditioning operation status adjustment command. The desired air conditioning operation status is then compared with preset air conditioning operation rules to determine whether the air conditioning in the vehicle meets the air conditioning control conditions. For example, if the desired air conditioning operation status matches the current operation status, or if the desired air conditioning operation status exceeds the current working range specified by the air conditioning operation rules, it is determined that the air conditioning in the vehicle does not meet the air conditioning control conditions. For instance, if the air conditioning has reached its maximum fan speed output, and an air conditioning operation status adjustment command to increase the fan speed is received, it is determined that the vehicle air conditioning does not meet the air conditioning control conditions, and a corresponding abnormal voice prompt can be provided to the user.

[0094] In this way, the logic operation of the central computing module can verify whether the air conditioning control command given by the user is reasonable, and then send the reasonable air conditioning control command to the domain controller for execution, which helps to improve the control accuracy in voice-controlled air conditioning scenarios.

[0095] S104. The area controller controls the operation of the car's air conditioning according to the air conditioning control command.

[0096] Here, upon receiving an air conditioning shutdown command, the zone controller immediately stops all actuators, and the air conditioning control interface displays the air conditioning off status. Upon receiving an air conditioning start command or an air conditioning operation status adjustment command, the zone controller converts the air conditioning control command into LIN format and controls the corresponding compressor, blower, and other actuators in the vehicle's air conditioning system via the LIN line to perform corresponding actions, such as changing their speed. The specific implementation of the zone controller controlling the vehicle's air conditioning system can be found in relevant technologies, and will not be elaborated upon here.

[0097] This disclosure provides a method for controlling an automotive air conditioner. The voice interaction device collects the user's voice and sends it to the infotainment system host. The infotainment system host generates an air conditioner control command based on the voice and sends it to the central processing module. The central processing module determines whether the vehicle meets the air conditioner control conditions based on the command type of the air conditioner control command. If the conditions are met, the central processing module sends the air conditioner control command to the area controller. The area controller controls the operation of the automotive air conditioner according to the air conditioner control command.

[0098] In this way, the air conditioning control system architecture, consisting of voice interaction devices, an entertainment information host, a central computing module, and a regional controller, can accurately generate air conditioning control commands by recognizing user voice. Based on the air conditioning control commands, it verifies whether the vehicle meets the air conditioning control conditions and sends the verified and reasonable air conditioning control commands to the regional controller to control the operation of the car's air conditioning. This achieves the goal of conveniently and accurately controlling the in-vehicle air conditioning through user voice, avoiding the driving safety risks caused by manual adjustment.

[0104] Furthermore, the entertainment information host 320 is equipped with a voice control application; the voice control application includes a voice recognition and processing module and a format conversion module;

[0105] The voice recognition and processing module is used to verify the voice; if the voice passes the verification, the verified voice is converted into the air conditioner control command and sent to the format conversion module.

[0107] Furthermore, the speech recognition and processing module is also used to identify speech information from the speech, generate a confirmation speech based on the speech information, and send the confirmation speech to the speech interaction device 310;

[0108] The voice interaction device 310 is also used to play the confirmation voice to confirm with the user whether the voice information is correct; and to collect the user's reply voice and send the reply voice to the voice recognition and processing module.

[0109] The speech recognition and processing module is further configured to determine that the speech has passed verification if it identifies a reply speech indicating confirmation from the reply speech.

[0110] Furthermore, the central processing module 330 is also used for:

[0111] If the air conditioning control command is an air conditioning off command, then the vehicle is determined to meet the air conditioning control conditions.

[0117] Furthermore, if the air conditioning control command is an air conditioning operation status adjustment command, the central processing module 330 is also used for:
