The age group of the occupant is determined based on the image features of the face image.

The corresponding suitable temperature is determined according to the age group, wherein the age group types include children, young people and old people, and the suitable temperatures corresponding to children, young people and old people increase in sequence.

Using the vehicle-mounted multi-temperature zone automatic air-conditioning control method provided by the application, the infrared temperature sensor is used to obtain the body surface temperature of the occupant, and compared with the appropriate temperature to obtain a comparison result, thereby judging whether the occupant's body surface temperature is appropriate according to the comparison result, Whether it is necessary to control the air-conditioning outlet corresponding to the member, so as to accurately adjust the corresponding air-conditioning outlet according to the body surface temperature of the occupant, and improve the adjustment accuracy of the multi-temperature zone automatic air-conditioning.

The embodiment of the present application provides another vehicle-mounted multi-temperature zone automatic air-conditioning control method, which is executed by the vehicle controller. The following uses the vehicle controller as an example to illustrate. As shown in Figure 2, the method includes steps S201, S202, and S203 , S204, S205 and S206, wherein:

In step S201, an in-vehicle camera is used to acquire a facial image of the occupant.

It is understandable that the in-vehicle camera can be integrated in the in-vehicle rearview mirror, so that the in-vehicle camera can be used to capture the face images of all occupants, including the driver, co-pilot, rear left passenger and rear right passenger. side occupant.

It can be understood that, in order to fully respect the privacy requirements of users, a first switch can be set in the vehicle multimedia system. After the first switch is turned on by touch, the camera in the car can acquire the face image of the occupant.

In step S202, the age group of the occupant is determined according to the image features of the face image.

It is understandable that due to the slightly different facial features of different age groups, the size of the face will increase from childhood to youth, and the wrinkles on the face will increase from youth to old age. It will increase, bags under the eyes will sag, and age spots will increase. Therefore, the age group identification model can be trained in advance using the image features of multiple sets of known image data, and the multiple sets of known data include multiple facial images of known age groups. The age group recognition model may be a neural network model. After the age group recognition model is trained, the face image captured by the camera in the car is input into the age group recognition model as input information, and the age group recognition model can determine the age group of the occupant according to the image features in the face image. The age range types include children, youth, and seniors.

In step S203, the corresponding suitable temperature is determined according to the age group.

The suitable temperature corresponding to children, young people and old people decreases in turn.

It is understandable that the average body temperature of different age groups is different. Among the three age groups of children, youth and old age, the average body temperature of children is the highest, the average body temperature of young people is in the middle, and the average body temperature of old people is the lowest.

In the embodiment of the present application, the suitable temperature may be related to the average body temperature corresponding to different age groups, and the suitable temperature corresponding to children, young people and old people decreases in turn. For example, the suitable temperature corresponding to children is 37 degrees Celsius, the suitable temperature corresponding to young people is 36.5 degrees Celsius, and the suitable temperature corresponding to old people is 36 degrees Celsius.

Specifically, the corresponding relationship between the age group and the suitable temperature may be stored in advance. After the age group is determined in step S201, the suitable temperature corresponding to the age group is determined in step S203 according to the age group and the above-mentioned corresponding relationship.

It can be understood that a corresponding occupant identification can be set for each occupant, for example, the occupant identification corresponding to the driver is 001, the occupant identification corresponding to the co-pilot is 010, and the occupant identification corresponding to the rear left passenger is 011, The occupant identification corresponding to the right occupant in the rear row is 100.

The age group of the occupant and the corresponding suitable temperature determined in steps S201-S203 can be in one-to-one correspondence with the occupant identification. The age group, suitable temperature and occupant identification are stored correspondingly.

In step S204, the body surface temperature of the occupant is acquired using an infrared temperature sensor.

In some optional embodiments, there are multiple infrared temperature sensors, which are respectively arranged on the left A pillar, the right A pillar, the left B pillar, and the right B pillar, and are set near the occupants in the vehicle, so as to obtain the nearest occupant's body temperature.

For example, the first infrared temperature sensor installed on the left A-pillar is used to obtain the driver's body surface temperature, and the second infrared temperature sensor installed on the right A-pillar is used to obtain the co-pilot's body surface temperature. The third infrared temperature sensor on the left B-pillar is used to obtain the body surface temperature of the rear left passenger, and the fourth infrared temperature sensor installed on the right B-pillar is used to obtain the body surface temperature of the rear right passenger.

In some optional embodiments, each occupant in the car has its corresponding air-conditioning outlet, for example, the air-conditioning outlet corresponding to the driver is at least two air-conditioning outlets arranged on the left side of the dashboard, and the auxiliary The air-conditioning outlets corresponding to driving are at least two air-conditioning outlets set on the right side of the instrument panel, and the air-conditioning outlets corresponding to the left passenger in the rear row are the air-conditioning outlets set on the left rear side of the armrest box, and the air-conditioning outlets on the right side of the rear row The air-conditioning outlet corresponding to the occupant is the air-conditioning outlet arranged on the right rear side of the armrest box.

It is also possible to pre-store the corresponding relationship between the air outlet identification of the air outlet of the air conditioner and the occupant identification, and one air outlet identification corresponds to only one occupant identification.

When the B-pillar of the vehicle is also provided with air-conditioning outlets, the air-conditioning outlets corresponding to the rear left passengers also include the air-conditioning outlets arranged on the left B-pillar, and the air-conditioning outlets corresponding to the rear right passengers It also includes the air-conditioning outlet set on the right B-pillar.

After the body surface temperature of each occupant is respectively obtained by using the infrared temperature sensor, the body surface temperature and the occupant identification can also be stored correspondingly.

In step S205, the body surface temperature is compared with the appropriate temperature to obtain a comparison result.

It can be understood that it is necessary to compare the body surface temperature and the suitable temperature with the same occupant identification. For example, the occupant identification corresponding to the co-pilot is 010. Steps S201-S203 determine that the age group corresponding to the occupant identification 010 is youth, suitable The temperature is 36.5 degrees Celsius, and it is determined by step S204 that the body surface temperature corresponding to the occupant identification 010 is 37 degrees Celsius. Then compare the body surface temperature of 37 degrees Celsius with the optimum temperature of 36.5 degrees Celsius to obtain the comparison result. The same applies to the driver, rear left passenger, and rear right passenger.

The comparison result can also be stored corresponding to the occupant identification.

In step S206, the air outlet of the air conditioner corresponding to the occupant is controlled according to the comparison result.

It can be understood that, since the comparison result corresponds to the occupant identification, and the occupant identification corresponds to the air outlet identification of the air outlet of the air conditioner, in step S206, the control and the occupant identification may be based on the comparison result corresponding to the occupant identification. The air outlet corresponding to the identification indicates the air outlet of the air conditioner corresponding to the identification.

In some optional embodiments, controlling the air conditioner outlet corresponding to the occupant according to the comparison result in step S206 includes:

When the comparison result indicates that the body surface temperature is lower than the optimum temperature, it is determined whether the temperature difference between the optimum temperature and the body surface temperature is less than a preset temperature threshold.

It can be understood that when the body surface temperature is lower than the appropriate temperature, it indicates that the occupant may feel a little cold. At this time, the degree of coldness is further judged by the magnitude relationship between the temperature difference and the preset temperature threshold.

In a possible judgment result, when the temperature difference is less than the preset temperature threshold, it means that the degree of coldness is not high, and the demand for heating is not too severe. At this time, control the air-conditioning outlet corresponding to the occupant to switch to the heating mode , adjust the temperature of the air-conditioning outlet corresponding to the occupant to the first temperature, and adjust the air volume of the air-conditioning outlet corresponding to the occupant to the first air volume. The temperature threshold may be 0.5 degrees Celsius.

It can be understood that the first temperature may be 28 degrees Celsius, and the first air volume may be a secondary air volume. There are five levels of air volume in total, and the air volume increases sequentially from level one to level five.

In some optional embodiments, in order to reduce energy consumption as much as possible, when the temperature difference is smaller than a preset temperature threshold, the temperature outside the vehicle may also be detected. When the temperature outside the vehicle is higher than the first temperature, the corresponding air outlet of the air conditioner is switched to the external circulation mode, and there is no need to switch the corresponding air outlet of the air conditioner to the heating mode.

In another possible judgment result, when the temperature difference is greater than the preset temperature threshold, it indicates that the degree of coldness is relatively high and the demand for heating is relatively severe. Adjust the temperature of the air-conditioning outlet corresponding to the occupant to the second temperature, and adjust the air volume of the air-conditioning outlet corresponding to the occupant to the second air volume, wherein the second temperature is higher than the first temperature, and the second temperature may be 30 degrees Celsius. The second air volume is greater than the first air volume, and the second air volume may be four-level air volume.

Similarly, in some optional embodiments, in order to reduce energy consumption as much as possible, when the temperature difference is greater than a preset temperature threshold, the outside temperature may also be detected. When the temperature outside the vehicle is higher than the second temperature, the corresponding air outlet of the air conditioner is switched to the external circulation mode, and there is no need to switch the corresponding air outlet of the air conditioner to the heating mode.

It can be understood that the air-conditioning outlet corresponding to each occupant can be controlled separately, and the temperature and air volume of each air-conditioning outlet can be individually controlled. When a specific air-conditioning outlet is switched to heating mode, the corresponding air outlet The channel heater can be turned on. According to the temperature, the power of the heater can be adjusted accordingly.

In addition to feeling cold, the occupant may also feel hot. Therefore, in some optional embodiments, controlling the air-conditioning outlet corresponding to the occupant according to the comparison result in step S206 includes:

When the comparison result indicates that the body surface temperature is greater than the optimum temperature, it is determined whether the temperature difference between the body surface temperature and the optimum temperature is less than a preset temperature threshold.

It can be understood that when the comparison result indicates that the body surface temperature is greater than the appropriate temperature, it indicates that the occupant feels hotter and needs to cool down. At this time, it is further judged whether the temperature difference between the body surface temperature and the appropriate temperature is less than the preset temperature threshold. So as to judge the intensity of cooling demand.

As one of the judgment results, when the temperature difference is less than the preset temperature threshold, it indicates that the cooling demand is not strong. The temperature is adjusted to the third temperature, and the air volume of the air-conditioning outlet corresponding to the occupants is adjusted to the first air volume. The third temperature may be 20 degrees Celsius, and the first air volume may be the second air volume.

In some optional embodiments, in order to reduce energy consumption as much as possible, when the temperature difference is smaller than a preset temperature threshold, the temperature outside the vehicle may also be detected. When the temperature outside the vehicle is lower than the third temperature, the corresponding air outlet of the air conditioner is switched to the external circulation mode, and there is no need to switch the corresponding air outlet of the air conditioner to the cooling mode.

As another judgment result, when the temperature difference is greater than the preset temperature threshold, it indicates that the demand for cooling is strong. The temperature is adjusted to the fourth temperature, and the air volume of the air-conditioning outlet corresponding to the occupant is adjusted to the second air volume, wherein the fourth temperature is lower than the third temperature, and the second air volume is greater than the first air volume. The fourth temperature may be 16 degrees Celsius, and the second air volume may be four-level air volume.

Similarly, in some optional embodiments, in order to reduce energy consumption as much as possible, when the temperature difference is greater than a preset temperature threshold, the outside temperature may also be detected. When the temperature outside the vehicle is lower than the fourth temperature, the corresponding air outlet of the air conditioner is switched to the external circulation mode, and there is no need to switch the corresponding air outlet of the air conditioner to the cooling mode.

It can be understood that the air-conditioning outlet corresponding to each occupant can be controlled separately, and the temperature and air volume of each air-conditioning outlet can be individually controlled. When a specific air-conditioning outlet is switched to cooling mode, the air duct corresponding to the air outlet The compressor can be turned on. According to the temperature, the rotation speed of the compressor and the opening degree of the expansion valve of the compressor can be adjusted accordingly.

It is understandable that humidity will also affect the body's perceived temperature. When the humidity is too high, the human body's tolerance to cold and heat will decrease. It will feel more stuffy in a hot environment than in a low humidity one. In some optional embodiments, it is also possible to set a humidity sensor for each occupant, use the humidity sensor to obtain the humidity value of the area where each occupant is located, compare the humidity value with the preset humidity threshold, and when the humidity value is greater than When the humidity threshold is preset, the air volume of the air conditioner is increased to five levels of air volume, so as to take away the water vapor in the environment faster, reduce the environmental humidity, and improve the comfort of the occupants.

Using the vehicle-mounted multi-temperature zone automatic air-conditioning control method provided by this application, the occupant's facial image is obtained in advance by the camera in the vehicle and the age group of the occupant is determined, so as to accurately determine the suitable temperature of the occupant according to the age group. Further use the infrared temperature sensor to obtain the body surface temperature of the occupant, and compare it with the suitable temperature to obtain the comparison result. Since the different suitable temperatures corresponding to the different age groups of the occupants are taken into account, the difference between the body surface temperature and the suitable temperature of the occupants is considered. According to the size relationship between them, it can be judged whether the occupant needs to heat up or cool down, so as to control the corresponding air outlet of the air conditioner, and improve the adjustment accuracy of the automatic air conditioner in multiple temperature zones.
