[0057] Introduction of air conditioner panel body:

[0058] In a possible implementation, the shape of the outer surface of the air conditioning panel body can be set and changed according to the interior shape of the vehicle, so as to match the interior style of the vehicle. The air conditioning panel body is often set in the middle of the center console of the vehicle cabin, so the shape of the outer surface of the air conditioning panel body matches the shape of the middle position of the center console of the vehicle cabin; for example, if the shape of the middle position of the center console of the vehicle cabin is an arc shape, the shape of the outer surface of the air conditioning panel body is also an arc shape.

[0059] In another possible implementation, the process of the outer surface of the air-conditioning panel body can adopt a variety of processes to provide diversity in the air-conditioning control panel, thereby meeting user needs; for example, the process of the outer surface of the air-conditioning panel body can be IML (In Molding Label) process, IME (In-Mold Electronics) or painting process, etc.

[0060] In another possible implementation, the color of the air conditioner panel body can be customized to different colors according to user requirements, so as to meet various user requirements. For example, the color of the air conditioner panel body can be customized to black, yellow or white.

[0061] Introduction of signal sensing sensor:

[0062] Please refer to Figure 2In a possible implementation, the signal sensing sensor includes a capacitive sensor, and the pulse signal is a voltage pulse signal. Accordingly, the capacitive sensor is used to detect that the outer surface of the air conditioner panel body is blocked, determine the capacitance change information of the outer surface of the air conditioner panel body, the capacitance change information is used to indicate the capacitance change of the outer surface of the air conditioner panel body caused by the outer surface of the air conditioner panel body being blocked, convert the capacitance change information into a voltage pulse signal, and send the voltage pulse signal to the MCU.

[0063] There are two situations in which the outer surface of the air-conditioning panel body is blocked. The first situation is that the outer surface of the air-conditioning panel body is blocked due to user's misoperation; the second situation is that the outer surface of the air-conditioning panel body is blocked due to air gesture operation triggered by the user.

[0064] The capacitive sensor is arranged on the back of the outer surface of the air conditioner panel body; and the capacitive sensor can sense the capacitance change of the outer surface of the air conditioner panel body. The user gesture starts from no contact until it approaches the outer surface of the air conditioner panel body. Under the influence of the human body magnetic field, the capacitance outside the air conditioner control panel will change. At this time, the capacitive sensor will receive the capacitance change. At this time, the capacitive sensor obtains the capacitance change information of the outer surface of the air conditioner panel body. The capacitance change information includes the capacitance change values ​​of multiple first sampling points in the first acquisition area of ​​the capacitive sensor, and the capacitance change value of any first sampling point is the difference between the capacitance value of the first sampling point and the initial capacitance value.

[0065] In one possible implementation, the capacitive sensor can generate a voltage pulse signal through the capacitance change value of the first sampling point; accordingly, the step of the capacitive sensor converting the capacitance change information into the voltage pulse signal can be: when there is a first sampling point in the first acquisition area whose capacitance change value is greater than a first preset value, the capacitive sensor generates a voltage pulse signal, and the voltage pulse signal is used to indicate that the capacitance change value of the first sampling point suddenly increases and then quickly returns to the original value, and the voltage pulse signal is used to indicate a short-term air gesture operation.

[0066] In another possible implementation, a first conversion model is stored in the capacitance sensor, and the first conversion model is used to convert capacitance change information into a voltage pulse signal; accordingly, the step of the capacitance sensor converting the capacitance change information into the voltage pulse signal may be: the capacitance sensor inputs the capacitance change information into the first conversion model and outputs the voltage pulse signal.

[0067] It should be noted that when the capacitive sensor detects that the outer surface of the air-conditioning panel body is blocked, it will continue to collect capacitance change information of the outer surface of the air-conditioning panel body, and convert the collected capacitance change information into a voltage pulse signal as soon as possible.

[0068] In another possible implementation, the pulse signal is a level pulse signal; please refer to Figure 3 , the signal sensing sensor includes an infrared sensor;

[0069] The infrared sensor is used to detect when the outer surface of the air-conditioning panel body is blocked, and determine the infrared change information of the outer surface of the air-conditioning panel body. The infrared change information is used to indicate the infrared change of the outer surface of the air-conditioning panel body caused by the outer surface of the air-conditioning panel body being blocked. The infrared change information is converted into a level pulse signal and the level pulse signal is sent to the MCU.

[0070] The infrared sensor is also arranged on the back of the outer surface of the air conditioning panel body, and the infrared sensor is welded to the circuit board by welding. When the user performs an air gesture operation without touching the outer surface of the air conditioning control panel, the infrared sensor dynamically captures the user's air gesture operation by sensing the infrared changes in the second collection area near the air conditioning control panel, and generates different high and low level pulse signals according to the user's air gesture operation and operation position. The infrared change information includes the infrared energy change values ​​of multiple second sampling points in the second collection area of ​​the infrared sensor, and the infrared energy change value of any second sampling point is the difference between the emitted infrared energy of the second sampling point and the infrared energy emitted back.

[0071] In a possible implementation, the infrared sensor generates a level pulse signal through the difference between the infrared energies at the second sampling points; accordingly, the step of the infrared sensor converting the infrared change information into the level pulse signal may be:

[0072] For any second sampling point in the second acquisition area, when the infrared energy change value of the second sampling point is greater than the second preset value, the infrared sensor converts the infrared energy change value of the second sampling point into a high-level pulse signal (binary 1); when the infrared energy change value of the second sampling point is not greater than the second preset value, the infrared sensor converts the infrared energy change value of the second sampling point into a low-level pulse signal (binary 0).

[0073] In another possible implementation, a second conversion model is stored in the infrared sensor, and the second conversion model is used to convert infrared change information into a level pulse signal; accordingly, the step of the infrared sensor converting the infrared change information into a level pulse signal may be: the infrared sensor inputs the infrared change information into the second conversion model and outputs a level pulse signal.

[0074] In another possible implementation, the pulse signal includes a voltage pulse signal and a level pulse signal; please refer to Figure 4,The signal sensing sensors include capacitive sensors and infrared sensors.

[0075] The capacitive sensor is used to detect when the outer surface of the air-conditioning panel body is blocked, determine the capacitance change information of the outer surface of the air-conditioning panel body, the capacitance change information is used to indicate the capacitance change of the outer surface of the air-conditioning panel body caused by the outer surface of the air-conditioning panel body being blocked, convert the capacitance change information into a voltage pulse signal, and send the voltage pulse signal to the MCU.

[0076] The infrared sensor is used to detect when the outer surface of the air-conditioning panel body is blocked, and determine the infrared change information of the outer surface of the air-conditioning panel body. The infrared change information is used to indicate the infrared change of the outer surface of the air-conditioning panel body caused by the outer surface of the air-conditioning panel body being blocked. The infrared change information is converted into a level pulse signal and the level pulse signal is sent to the MCU.

[0077] Introduction of MCU:

[0078] In a possible implementation, the pulse signal is a voltage pulse signal. The MCU is used to determine the second air gesture operation corresponding to the voltage pulse signal based on the voltage pulse signal, and determine the second air gesture operation as the air gesture operation on the outer surface of the air conditioner panel body.

[0079] The MCU stores a second gesture recognition model; the second gesture recognition model is used to determine the air gesture operation corresponding to the voltage pulse signal based on the voltage pulse signal; accordingly, the MCU determines the second gesture recognition operation corresponding to the voltage pulse signal based on the voltage pulse signal in the following steps: the MCU inputs the voltage pulse signal into the second gesture recognition model, and outputs the second air gesture operation. The second air gesture operation can be a sliding operation, a jogging operation, and a toggling operation.

[0080] In another possible implementation, the pulse signal is a level pulse signal. The MCU is used to determine the first air gesture operation corresponding to the level pulse signal based on the level pulse signal, and determine the first air gesture operation as the air gesture operation on the outer surface of the air conditioner panel body.

[0081] The MCU stores a first gesture recognition model; the first gesture recognition model is used to determine the air gesture operation corresponding to the level pulse signal based on the level pulse signal; accordingly, the MCU determines the first gesture recognition operation corresponding to the level pulse signal based on the level pulse signal in the following steps: the MCU inputs the level pulse signal into the first gesture recognition model, and outputs the first air gesture operation. The first air gesture operation can be a sliding operation, a jogging operation, and a toggling operation.

[0082] In another possible implementation, the pulse signal includes a level pulse signal and a voltage pulse signal; and the voltage pulse signal is used for misoperation verification; accordingly, the step of the MCU determining the air gesture operation on the outer surface of the air-conditioning panel body based on the pulse signal may be: the MCU performs misoperation detection on the air gesture operation based on the voltage pulse signal; when the air gesture operation is not a misoperation, the first air gesture operation corresponding to the level pulse signal is determined based on the level pulse signal, and the first air gesture operation is determined as the air gesture operation on the outer surface of the air-conditioning panel body.

[0083] Among them, the steps for MCU to detect misoperation of air gesture operation based on voltage pulse signal can be: when the duration of the voltage pulse signal exceeds the preset duration, the MCU determines that the air gesture operation is not an misoperation; when the duration of the voltage pulse signal does not exceed the preset duration, the MCU determines that the air gesture operation is an misoperation.

[0084] In the case where the air gesture operation is an erroneous operation, the air conditioning control signal is not sent to the actuator, and the user operation is not performed to prevent the user from making an erroneous operation. In addition, when the MCU determines that the air gesture operation is an erroneous operation, the MCU can send a notification message to the infrared sensor, and the notification message is used to notify the infrared sensor to stop collecting infrared change information to save the power consumption of the entire vehicle. Alternatively, when the MCU determines that the air gesture operation is an erroneous operation, after the MCU receives the infrared change information sent by the infrared sensor, it discards the infrared change information, that is, it does not process the infrared change information to save the power consumption of the entire vehicle.

[0085] In another possible implementation, the pulse signal includes a level pulse signal and a voltage pulse signal, and both the voltage pulse signal and the level pulse signal are used to determine the air gesture operation; accordingly, the steps for the MCU to determine the air gesture operation on the outer surface of the air-conditioning panel body based on the pulse signal may be: the MCU determines the first air gesture operation corresponding to the level pulse signal based on the level pulse signal; determines the second air gesture operation corresponding to the voltage pulse signal based on the voltage pulse signal; and determines the air gesture operation on the outer surface of the air-conditioning panel body based on the first air gesture operation and the second air gesture operation.

[0086] In one possible implementation, when the first air gesture operation and the second air gesture operation are the same, the MCU determines that the air gesture operation on the outer surface of the air conditioning panel body is the first air gesture operation (or the second air gesture operation). In another possible implementation, when the first air gesture operation and the second air gesture operation are not the same, the MCU determines that the air gesture operation on the outer surface of the air conditioning panel body is an erroneous operation.

[0087] The MCU is configured to determine, when the air gesture operation is an air sliding operation, based on the air sliding operation, that the air conditioning control instruction is to adjust the set temperature of the air conditioning panel body based on the first temperature control adjustment granularity;

[0088] an actuator, for determining, when the air gesture operation is an air swiping operation, based on the air swiping operation, that the air conditioning control instruction is to adjust the set temperature of the air conditioning panel body based on the second temperature control adjustment granularity;

[0089] an actuator, for determining, when the air gesture operation is an air jog operation, based on the air jog operation, that the air conditioning control instruction is to adjust the set temperature of the air conditioning panel body based on the third temperature control adjustment granularity;

[0090] The first temperature control adjustment granularity is greater than the second temperature control adjustment granularity, and the second temperature control adjustment granularity is greater than the third temperature control adjustment granularity. The air conditioning control instruction can be a low-level signal; the actuator performs corresponding actions based on the low-level signal output by the MCU.

[0091] For example, the first temperature control adjustment granularity is 5 degrees; when the air gesture operation is an air sliding operation and the sliding direction of the air sliding operation is upward, the MCU determines that the control instruction is to increase the set temperature of the air-conditioning panel body by 5 degrees; when the air gesture operation is an air sliding operation and the sliding direction of the air sliding operation is downward, the MCU determines that the control instruction is to reduce the set temperature of the air-conditioning panel body by 5 degrees.

[0092] The second temperature control adjustment force is 1 degree; when the air gesture operation is an air jog operation, and the jog position of the air jog operation is in the upper half of the air-conditioning control panel, the MCU determines that the control instruction is to increase the set temperature of the air-conditioning panel body by 1 degree; when the air gesture operation is an air jog operation, and the jog position of the air jog operation is in the lower half of the air-conditioning control panel, the MCU determines that the control instruction is to reduce the set temperature of the air-conditioning panel body by 1 degree.

[0093] The third temperature control adjustment strength is 2 degrees; when the air gesture operation is an air dial operation, and the dial position of the air dial operation is in the upper half of the air-conditioning control panel, the MCU determines that the control instruction is to increase the set temperature of the air-conditioning panel body by 1 degree; when the air gesture operation is an air dial operation, and the dial position of the air dial operation is in the lower half of the air-conditioning control panel, the MCU determines that the control instruction is to reduce the set temperature of the air-conditioning panel body by 2 degrees.

[0094] Display organization introduction:

[0095] The display mechanism is used to adjust at least one of the sound signal, light intensity and vibration frequency of the display mechanism based on the air conditioner display instruction.

[0096] The display mechanism displays changes according to the requirements of the actuator; for example, if the actuator increases the set temperature of the air-conditioning panel body by 5 degrees, the display mechanism will increase the sound, light intensity and vibration frequency; for another example, if the actuator reduces the set temperature of the air-conditioning panel body by 5 degrees, the display mechanism will reduce the sound, light intensity and vibration frequency, thereby providing timely feedback to the user on the execution effect of the air gesture operation through the display mechanism, and then quickly responding to the user in advance, providing obvious subjective feedback, achieving a high interactive effect with the user, and improving intelligence and user operation comfort.

[0097] In addition, the embodiment of the present application can provide users with diverse scene experiences, efficient and clear feedback, increase user-car interaction, improve user experience, and improve the comfort and functionality of the cabin by adjusting at least one of the sound signal, light intensity, and vibration frequency of the display mechanism, or by providing a change prompt of voice reminder, etc.

[0098] For example, please refer to 5. The user performs an air gesture operation on the outer surface of the air-conditioning panel body (without touching the outer surface of the air-conditioning panel body). The infrared sensor obtains infrared change information and converts the infrared change information into a level pulse signal. The capacitive sensor obtains capacitance change information and converts the capacitance change information into a voltage pulse signal. The level pulse signal and the voltage pulse signal are sent to the MCU. The MCU converts the level pulse signal and the voltage pulse signal into an air-conditioning control instruction (low-level signal), and transmits the air-conditioning control instruction to the actuator. The actuator executes the air-conditioning control instruction and controls the display mechanism to display the control effect of the control instruction.

[0099] Please refer to Figure 6 , which shows a flow chart of a method for controlling a vehicle air conditioner according to an exemplary embodiment of the present application. Figure 6 , the method comprising:

[0100] Step 601: When the outer surface of the air-conditioning panel body of the vehicle is blocked, the air-conditioning controller determines the signal change information of the outer surface of the air-conditioning panel body, and the signal change information is used to indicate the signal change of the outer surface of the air-conditioning panel body caused by the outer surface of the air-conditioning panel body being blocked.

[0101] The air-conditioning controller may be an MCU, and the air-conditioning controller obtains capacitance change information and infrared change information through a capacitance sensor and / or an infrared sensor.
