[0019] Figure 1 This is a flowchart of a vehicle air conditioning control method provided in an example embodiment of this disclosure, such as... Figure 1 As shown, the vehicle air conditioning control method may include:

[0020] S101: Detects vehicle startup or high voltage power-on, obtains the ambient temperature of the vehicle.

[0021] An air conditioning controller can be installed in the vehicle. When the vehicle is started or the high voltage is applied, the air conditioning will automatically turn on according to the ambient temperature. This allows the air conditioning to turn on automatically without the user having to manually turn it on or operate it remotely via a mobile app.

[0022] The air conditioning will only turn on automatically if the engine is started or the high-voltage power is applied, indicating that the user needs to drive. The air conditioning will not turn on automatically if the engine is not started or the high-voltage power is applied.

[0023] For traditional gasoline vehicles, the air conditioning can be turned on when the engine is detected to be starting; for hybrid or electric vehicles, the electric air conditioning can be turned on when high voltage is detected. High voltage refers to the vehicle's voltage being greater than or equal to a set voltage. The set voltage is determined based on actual conditions or empirical values, and will not be limited or elaborated upon in this embodiment.

[0024] In practical applications, most vehicles have eliminated the physical switch for air conditioning. Instead, the air conditioning switch is developed as software and integrated into the multimedia screen. However, due to the limited startup speed of the multimedia screen, users have to wait for the multimedia screen to start up before they can turn on the air conditioning. While waiting, the car becomes extremely stuffy and the air conditioning cannot be turned on, resulting in a poor user experience.

[0025] In this embodiment, when the vehicle is started or the high voltage is powered on, the air conditioner can be turned on automatically based on the ambient temperature of the vehicle, without having to wait for the multimedia screen to turn on before the air conditioner can be turned on, thus shortening the air conditioner's turn-on time and improving the user experience.

[0026] S102: Compare the ambient temperature with the temperature threshold to determine whether to automatically turn on the air conditioner.

[0027] After the user gets into the car and starts the vehicle, the system can automatically determine whether to turn on the air conditioning based on the ambient temperature. If the ambient temperature is greater than or equal to the temperature threshold, the air conditioning will be turned on automatically.

[0028] This embodiment takes a hot summer weather scenario as an example. The principle of automatically turning on the air conditioner in other scenarios is similar, and will not be described in detail in this embodiment.

[0029] In one example, the ambient temperature of the vehicle may include the interior temperature, and the air conditioning will be automatically turned on when the interior temperature is greater than or equal to a set temperature threshold.

[0030] In one example, the ambient temperature of the vehicle may include the outside temperature, and the air conditioning will be automatically turned on when the outside temperature is greater than or equal to a set temperature threshold.

[0031] In one example, the ambient temperature of the vehicle may include both the interior temperature and the exterior temperature. Comparing the ambient temperature to a temperature threshold to determine whether to automatically turn on the air conditioning may include:

[0032] The system compares the interior temperature with a first temperature threshold and the exterior temperature with a second temperature threshold. When the interior temperature is greater than or equal to the first temperature threshold and the exterior temperature is greater than or equal to the second temperature threshold, the air conditioning is automatically turned on.

[0033] In this embodiment, the air conditioning controller collects the outside and inside temperatures of the vehicle using both an outside temperature sensor and an inside temperature sensor. The air conditioning is automatically activated when the outside temperature is greater than or equal to a second temperature threshold T2℃, and the inside temperature is greater than or equal to a first temperature threshold T3℃. If only the inside temperature is used to determine whether to activate the air conditioning, there is a risk of misjudging the situation by activating the air conditioning when the outside temperature is low but the inside temperature is high. For example, in autumn or winter, when the outside temperature is low, it is necessary to avoid erroneously activating the air conditioning when the inside temperature is high due to starting the vehicle or connecting high-voltage electricity. Activating the air conditioning automatically when both the inside and outside temperatures exceed the respective temperature thresholds improves the accuracy of automatic air conditioning activation. However, in practical applications, if the vehicle is only equipped with an inside or outside temperature sensor, determining whether to activate the air conditioning solely based on comparing the inside or outside temperature sensor with the temperature threshold is also within the scope of this embodiment.

[0034] The two temperature thresholds, T2 and T3, can be calibrated by the air conditioner controller. In one example, T2 = 28°C and T3 = 32°C.

[0035] The vehicle air conditioning control method provided in this disclosure automatically turns on the air conditioning according to the ambient temperature of the vehicle after detecting that the vehicle is started or the high voltage is powered on. This can achieve automatic turning on of the vehicle air conditioning without the need for the user to manually turn it on or operate it remotely using a mobile APP.

[0036] In one example embodiment of this disclosure, automatically turning on the air conditioner may include:

[0037] Control the air conditioner to start when powered on and to operate it according to the preset mode.

[0038] The air conditioning controller can connect to the Engine Control Module (ECM) or Vehicle Control Unit (VCU) via a Controller Area Network (CAN). When the air conditioning controller determines to automatically turn on the air conditioning based on the ambient temperature, it sends an air conditioning start-up request signal to the ECM or VCU via the CAN network. The ECM or VCU then controls the closing of the relay between the air conditioning compressor and the power supply, thereby powering on and starting the vehicle's air conditioning system. After the air conditioning system is powered on and started, the air conditioning controller can control the air conditioning to operate according to a preset mode.

[0039] In one example, controlling the air conditioner to operate according to a preset mode may include:

[0040] It obtains the operating parameters set by the user through the multimedia screen and controls the air conditioner to operate according to the operating parameters.

[0041] The air conditioner controller can connect to a multimedia interface (MMI) via a CAN network, interact with the user through the MMI, obtain the air conditioner's operating parameters input by the user, and control the air conditioner's operating mode according to the operating parameters input by the user on the MMI.

[0042] The operating parameters of the air conditioner can be set through the MMI. The operating parameters of the air conditioner may include at least one of the following: the temperature (T1℃) when the air conditioner is actively turned on, the air volume, the mode, and the internal and external circulation.

[0043] In one example, controlling the air conditioner to operate according to a preset mode may include:

[0044] Retrieve stored preset operating parameters and control the air conditioner to operate according to the preset operating parameters.

[0045] In this embodiment, the correspondence between the vehicle interior temperature and the air conditioning operating parameters can be preset or stored in the air conditioning controller. The air conditioning operating parameters that match the vehicle interior temperature can be obtained according to the correspondence. The air conditioning controller controls the air conditioning operating mode based on the pre-stored operating parameters that match the vehicle interior temperature.

[0046] The air conditioner's operating parameters can be set via the MMI. If the user does not make any settings, the default settings will be used. The default settings can be the operating parameters pre-stored in the air conditioner controller. The operating parameters corresponding to the default settings can include at least one of the following: the lowest temperature when the air conditioner is actively turned on, the maximum airflow, the face + foot blowing mode, and the internal circulation mode.

[0047] In one example embodiment of this disclosure, the vehicle air conditioning control method may further include:

[0048] Determine if the air conditioner has a memory function, and determine if the air conditioner was on when it was last turned off.

[0049] Controlling the air conditioner to operate according to a preset mode can include:

[0050] If the air conditioner has a memory function and was on when it was last turned off, control the air conditioner to operate in its built-in smart mode. In the smart mode, the air conditioner can automatically adjust its operating parameters based on existing memory.

[0051] In this embodiment, it can be determined whether the air conditioning has a memory function after the vehicle is started. For vehicles with air conditioning memory function, if the air conditioning was on when the engine was last turned off, the air conditioning will automatically turn on in the built-in intelligent mode (AUTO mode) after the vehicle is started this time. If the air conditioning was off when the engine was last turned off, or for vehicles without air conditioning memory function, the system will determine whether to automatically turn on the air conditioning based on the ambient temperature of the vehicle after the vehicle is started this time.

[0052] In one example, the model number of the vehicle's air conditioner can be stored in the air conditioning controller, which can then determine whether the air conditioner has a memory function based on the pre-stored model number.

[0053] In one example embodiment of this disclosure, before automatically turning on the air conditioner, the following may be included:

[0054] Check if the automatic air conditioning setting on the vehicle's multimedia screen is set to "on"; if it is, determine whether the air conditioning will turn on automatically.

[0055] Figure 2 This is a schematic diagram of a multimedia screen provided in an example embodiment of the present disclosure, such as... Figure 2As shown, users can select whether to automatically turn on the air conditioning via the automatic air conditioning setting option on the multimedia screen. When the automatic air conditioning setting option is set to "on," the air conditioning controller determines whether to automatically turn on the air conditioning based on the ambient temperature of the vehicle.

[0056] In one example embodiment of this disclosure, after automatically turning on the air conditioner, the system may further include:

[0057] The air conditioner is turned on by sending an air conditioner-on signal to the multimedia screen via the CAN network. The air conditioner-on signal is used to instruct the multimedia screen to remind the user that the air conditioner has been turned on via voice and pop-up window.

[0058] When the vehicle is started or connected to high voltage, if the temperature inside and outside the vehicle exceeds the threshold, the air conditioner will automatically turn on and provide a voice and pop-up notification that the air conditioner is on.

[0059] The air conditioning controller can send the air conditioning turn-on signal to the CAN network. After the MMI receives the air conditioning turn-on signal through the CAN network, it can remind the user through voice and pop-up window that "the temperature inside the vehicle is high and the air conditioning has been automatically turned on for you".

[0060] In one example embodiment of this disclosure, after automatically turning on the air conditioner, the system may further include:

[0061] The system detects whether the multimedia screen sends an air conditioner shutdown signal via the CAN network. The air conditioner shutdown signal is either input information or voice information from the user indicating to turn off the air conditioner via the multimedia screen. When the multimedia screen sends the air conditioner shutdown signal via the CAN network, the air conditioner is automatically turned off.

[0062] After the air conditioner turns on automatically, users can turn it off by saying "Turn off the air conditioner" via voice or by operating the air conditioner switch. If no operation is performed, the air conditioner will remain on.

[0063] The MMI can obtain the user's voice message or input message to turn off the air conditioner and send it to the CAN network. If the air conditioner controller detects the voice message or input message to turn off the air conditioner in the CAN network, it will turn off the air conditioner.

[0064] Figure 3 A flowchart of a vehicle air conditioning control method provided in another embodiment of this disclosure is shown below. Figure 3 As shown, the vehicle air conditioning control method may include:

[0065] S301: Vehicle unlock detected. Start the engine or apply high voltage.

[0066] The automatic air conditioning system can be turned on and off via the MMI (Manual Management System). Parameters such as temperature (T1℃), airflow, mode, and internal / external air circulation can all be set through the MMI. Setting the automatic air conditioning option to "On" will activate the automatic air conditioning logic. After user settings are configured, the automatic air conditioning will operate according to the user's settings. If no settings are configured by the user, the default settings will be used, which can be set to the lowest temperature, highest airflow, face and foot blowing mode, and internal circulation.

[0067] S302: Determine the air conditioner status before the last power outage. If the air conditioner was on before the last power outage, execute S303; if the air conditioner was off before the last power outage, execute S304.

[0068] The air conditioning will only turn on automatically if the engine is started or high-voltage power is applied, indicating that the user needs to drive. It will not turn on automatically if the engine is not started or high-voltage power is applied. The air conditioning will turn on automatically when the user unlocks the vehicle and starts the engine (for conventional vehicles) or applies high-voltage power (for hybrid or pure electric vehicles).

[0069] S303: The air conditioner automatically turns on AUTO mode.

[0070] For cars with an air conditioning memory function, if the air conditioning was on when the engine was last turned off, it will automatically turn on when the vehicle is started without checking whether to turn it on automatically. If the air conditioning was off when the engine was last turned off, or if it was off when the engine was last turned off, this step is skipped, and S304 is executed directly.

[0071] S304: Determine whether the automatic air conditioning function is enabled. If yes, proceed to S306; otherwise, proceed to S305.

[0072] S305: The air conditioner does not turn on automatically.

[0073] The system determines whether the automatic air conditioning function is on. If the automatic air conditioning function is not on, the air conditioning will not turn on automatically. If the automatic air conditioning setting option on the multimedia screen is set to "On", the automatic air conditioning function is confirmed to be on; if the automatic air conditioning setting option on the multimedia screen is set to "Off", the automatic air conditioning function is confirmed to be off.

[0074] S306: Determine if the outside temperature is ≥ T2℃ and the inside temperature is ≥ T3℃. If yes, proceed to S307; otherwise, proceed to S305.

[0075] The system determines whether the active air conditioning function is turned on. If the active air conditioning function is turned on, the air conditioning controller collects the outside temperature and the inside temperature through the outside temperature sensor and the inside temperature sensor, respectively. When the outside temperature is ≥ T2℃ and the inside temperature is ≥ T3℃, the air conditioning will be turned on automatically according to the user-set parameters or the default settings.

[0076] S307: Automatically turns on the air conditioner, sets the temperature to T1℃, and provides a pop-up reminder and voice prompt to the user to turn on the air conditioner.

[0077] The air conditioning controller sends the air conditioning turn-on signal to the CAN network, and the MMI reminds the user via voice and pop-up window that "the temperature inside the vehicle is high and the air conditioning has been automatically turned on for you."

[0078] S308: Determine if the user has adjusted the air conditioning settings. If yes, proceed to S309; ​​otherwise, proceed to S310.

[0079] S309: Control the air conditioner according to user settings.

[0080] S310: Air conditioning remains on automatically.

[0081] After the air conditioner turns on automatically, users can turn it off by saying "Turn off the air conditioner" via voice or by operating the air conditioner switch. If no operation is performed, the air conditioner will remain on.

[0082] Figure 4 This is a structural block diagram of an air conditioner controller provided in an example embodiment of the present disclosure, such as... Figure 4 As shown, the air conditioner controller may include: a memory 41 and a processor 42.

[0083] The memory stores execution instructions. The processor can be a Central Processing Unit (CPU), an Application Specific Integrated Circuit (ASIC), or one or more integrated circuits that implement embodiments of this invention. When the air conditioner controller is running, the processor communicates with the memory, and the processor invokes execution instructions to perform the following operations:

[0084] The system detects vehicle startup or high-voltage power-on and obtains the ambient temperature of the vehicle.

[0085] The ambient temperature is compared with a temperature threshold to determine whether the air conditioner should be turned on automatically.

[0086] An air conditioning controller can refer to a regular air conditioning controller, or it can refer to a controller with air conditioning control functions. In practical applications, some vehicles do not have an air conditioning controller (CCM). In such cases, the air conditioning control function of the CCM can be integrated into the Body Domain Controller (BGM), where the BGM acts as the air conditioning controller.

[0087] In one example embodiment of this disclosure, the ambient temperature may include: the vehicle interior temperature and the vehicle exterior temperature; the processor compares the ambient temperature with a temperature threshold to determine whether to automatically turn on the air conditioning, which may include:

[0088] The vehicle interior temperature is compared with a first temperature threshold, and the vehicle exterior temperature is compared with a second temperature threshold; when the vehicle interior temperature is greater than or equal to the first temperature threshold and the vehicle exterior temperature is greater than or equal to the second temperature threshold, the air conditioning is automatically turned on.

[0096] Determine whether the air conditioner has a memory function, and determine whether the air conditioner was on when it was last turned off;

[0097] The processor controls the air conditioner to operate according to a preset mode, which may include:

[0098] When the air conditioner has a memory function and was in the on state when it was last turned off, the air conditioner is controlled to operate in the intelligent mode. In the intelligent mode, the air conditioner can automatically adjust its operating parameters based on existing memory.

[0099] In one example embodiment of this disclosure, the processor is further configured to:

[0100] Before automatically turning on the air conditioning, check if the automatic air conditioning setting option on the vehicle's multimedia screen is set to "on"; if it is set to "on", determine whether to automatically turn on the air conditioning.

[0101] In one example embodiment of this disclosure, the processor is further configured to:

[0102] After the air conditioner is automatically turned on, an air conditioner turn-on signal is sent to the multimedia screen via the CAN network. The air conditioner turn-on signal is used to instruct the multimedia screen to remind the user that the air conditioner has been turned on via voice and pop-up window.

[0103] In one example embodiment of this disclosure, the processor is further configured to:

[0104] After the air conditioner is automatically turned on, it is detected whether the multimedia screen sends an air conditioner off signal through the CAN network. The air conditioner off signal is input information or voice information from the user indicating to turn off the air conditioner through the multimedia screen.

[0105] When the multimedia screen sends an air conditioner off signal via the CAN network, the air conditioner is automatically turned off.

[0106] Figure 5 This is a structural block diagram of an air conditioning control system provided in an example embodiment of the present disclosure, such as... Figure 5 As shown, the air conditioning control system may include: the air conditioning controller 51 shown in any embodiment.

[0107] The air conditioning controller is used to execute the vehicle air conditioning control method shown in any of the above embodiments. Its implementation principle and effect are similar, and will not be described again here.

[0108] In one example embodiment of this disclosure, the air conditioning control system may further include a multimedia screen 52, and the air conditioning controller and the multimedia screen are connected via a CAN network.

[0109] The multimedia screen is configured to detect the operating parameters input by the user and send them to the air conditioner controller; it also receives the start signal sent by the air conditioner controller via the CAN network and reminds the user that the air conditioner has been turned on via voice and pop-up window when the start signal is received.

[0110] The air conditioner controller can connect to a multimedia interface (MMI) via a CAN network, interact with the user through the MMI, obtain the air conditioner's operating parameters input by the user, and control the air conditioner's operating mode according to the operating parameters input by the user on the MMI.

[0111] The operating parameters of the air conditioner can be set through the MMI. The operating parameters of the air conditioner may include at least one of the following: the temperature (T1℃) when the air conditioner is actively turned on, the air volume, the mode, and the internal and external circulation.

After the MMI receives the air conditioning turn-on signal through the CAN network, it can remind the user through voice and pop-up window that "the temperature inside the car is high and the air conditioning has been turned on automatically for you".

[0113] In one example, the MMI can acquire the user's voice message or input message to turn off the air conditioner and send it to the CAN network. If the air conditioner controller detects the voice message or input message to turn off the air conditioner in the CAN network, it will turn off the air conditioner.

[0114] In one example embodiment of this disclosure, the air conditioning control system may further include: an outside temperature sensor and an inside temperature sensor, which are respectively connected to the air conditioning controller via a hardwire or a CAN network.

[0115] The outside temperature sensor is set to detect the outside temperature and send it to the air conditioning controller; the inside temperature sensor is set to detect the inside temperature and send it to the air conditioning controller.

[0116] The air conditioning controller collects the outside temperature and the inside temperature of the vehicle through the outside temperature sensor and the inside temperature sensor, respectively. When the outside temperature is ≥ T2℃ and the inside temperature is ≥ T3℃, the air conditioning will be turned on automatically according to the user-set parameters or the default settings.
