[0050] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0051] The seat temperature control method provided in the embodiment of the present application can be applied to Figure 1In the application environment shown. Among them, the vehicle controller 102 communicates with the server 104 through a wired network or a wireless network. The data storage system can store the data that the server 104 needs to process. The data storage system can be integrated on the server 104, or it can be placed on the cloud or other network servers. Specifically, the vehicle controller 102 can obtain the seat temperature of the seat in the target vehicle, as well as the atmospheric temperature outside the target vehicle and the body surface temperature of the pedestrian, and perform weighted summation processing on the seat temperature, atmospheric temperature and body surface temperature to obtain the ambient temperature. When the associated device of the target vehicle is detected, the seat is temperature-controlled according to the ambient temperature. The vehicle controller 102 can also send the seat temperature of the seat in the target vehicle, the atmospheric temperature outside the target vehicle and the body surface temperature of the pedestrian to the server 104 through the network, so that after the server 104 obtains the seat temperature of the seat in the target vehicle, the atmospheric temperature outside the target vehicle and the body surface temperature of the pedestrian, the seat temperature, atmospheric temperature and body surface temperature are weighted summation processing to obtain the ambient temperature. When the associated device of the target vehicle is detected, the seat is temperature-controlled according to the ambient temperature.

[0052] The server 104 may be an independent vehicle-mounted physical server, a server cluster or distributed system composed of multiple physical servers, or a cloud server that provides cloud computing services.

[0053] In an exemplary embodiment, Figure 2 As shown, a seat temperature control method is provided, comprising:

[0054] S201, obtaining the seat temperature of the seat in the target vehicle, and obtaining the atmospheric temperature outside the target vehicle and the body surface temperature of the pedestrian.

[0055] Among them, the seats in the target vehicle can be divided into multiple parts such as a backrest, a seat cushion, a head support and a leg support, and the seat temperature of each part of the multiple seats in the target vehicle can be obtained separately.

[0056] Optionally, the seat temperatures of various parts of multiple seats in the target vehicle are acquired through a temperature sensor or an infrared thermal imaging system.

[0057] Optionally, based on the current position of the target vehicle, the atmospheric temperature outside the target vehicle is obtained from the server via the network.

[0058] Among them, pedestrians outside the target vehicle refer to pedestrians within a certain range from the target vehicle, and the range size can be a preset value.

[0059] Optionally, the body surface temperature of pedestrians outside the target vehicle is acquired by an infrared thermal imaging system.

[0060] Optionally, the body surface temperatures of multiple pedestrians outside the target vehicle are obtained, and then the average temperature of the body surface temperatures of the multiple pedestrians is taken as the required body surface temperature.

[0061] S202, performing weighted sum processing on the seat temperature, the air temperature and the body surface temperature to obtain the ambient temperature.

[0062] Corresponding weights are assigned to the seat temperature, the atmospheric temperature and the body surface temperature, and then the seat temperature, the atmospheric temperature and the body surface temperature are weighted and summed according to the corresponding weights to obtain the ambient temperature for the target vehicle.

[0063] Exemplarily, the ambient temperature is calculated using the following formula:

[0064] ;

[0065] Among them, T 0 is the ambient temperature, α, β and γ are the weights corresponding to the seat temperature, the air temperature and the body surface temperature respectively, T b is the seat temperature, T d is the atmospheric temperature, T y Is the body surface temperature.

[0066] S203: When the associated device of the target vehicle is detected, the temperature of the seat is controlled according to the ambient temperature.

[0067] Among them, the associated device of the target vehicle can be any smart device pre-bound to the target vehicle, such as the user's mobile phone, watch, etc. The associated device of the target vehicle can also be a movable vehicle part bound to the target vehicle, such as the key of the target vehicle.

[0068] For example, when the user's mobile phone, watch or other associated devices are detected through short-range communication technologies such as WiFi (wireless network communication technology), Bluetooth, and NFC (Near Field Communication), it is determined that the user is close to the target vehicle and is more likely to get on the vehicle. Therefore, before the user gets on the vehicle, the seat temperature is controlled according to the ambient temperature.

[0069] For example, when a radio frequency signal emitted by the key of the target vehicle is detected by a radio frequency receiver, or when an infrared signal emitted by the key of the target vehicle is detected by an infrared receiver, it is determined that the user is close to the target vehicle and is more likely to get in the vehicle. Therefore, before the user gets in the vehicle, the seat temperature is controlled according to the ambient temperature.

[0070] Specifically, when the ambient temperature is low, the seat temperature is increased, and when the ambient temperature is high, the seat temperature is decreased, thereby providing users with a more comfortable driving or riding experience.

[0071] Optionally, when the seat temperatures of various parts of the seat in the target vehicle are acquired, the seat temperatures of different parts of the seat may be adjusted separately to further optimize the driving or riding experience.

[0072] In the above seat temperature control method, the seat temperature of the seat in the target vehicle is obtained, as well as the atmospheric temperature outside the target vehicle and the pedestrian's body surface temperature; the seat temperature, atmospheric temperature and body surface temperature are weighted and summed to obtain the ambient temperature; when the associated equipment of the target vehicle is detected, the seat is temperature controlled according to the ambient temperature. This embodiment combines the real-time temperature of multiple dimensions inside and outside the vehicle to determine the corresponding ambient temperature, and then controls the temperature of the seat according to the ambient temperature. Compared with the prior art of directly heating the seat, this application can not only improve the rationality and accuracy of the seat temperature control, but also has higher flexibility. In addition, this application controls the temperature of the seat when the associated equipment of the target vehicle is detected. The seat can be temperature controlled before the user sits down or even before the user enters the vehicle, which greatly improves the predictability of the seat temperature control and provides a more timely and effective seat temperature control function.

[0073] As an optional implementation manner in this embodiment, the associated device of the target vehicle includes a key of the target vehicle, and when a radio frequency signal sent by the key of the target vehicle is received, it can be determined that the associated device of the target vehicle is detected.

[0074] Therefore, in scenarios where the network quality is poor or the network is not deployed, or in scenarios where the user does not carry an associated smart device, the target vehicle can also promptly determine that the user is close to the target vehicle and is more likely to get on the vehicle. The above implementation can effectively avoid limitations in actual application scenarios and ensure that the associated devices of the target vehicle are detected in a timely manner.

[0075] In an exemplary embodiment, Figure 3 As shown, the above S201 includes:

[0076] S301, collecting the seat temperature of the seat in the target vehicle through the in-vehicle infrared thermal imaging system.

[0077] Among them, the seats include the driver's seat and the non-driver's seat, and the non-driver's seat includes the passenger seat and the back seat.

[0078] The target vehicle is equipped with an in-vehicle infrared thermal imaging system, which can simultaneously collect the temperature of different parts of each seat in the target vehicle to obtain the seat temperature of different parts of each seat in the target vehicle.

[0079] S302, collecting the atmospheric temperature outside the target vehicle through a temperature sensor.

[0080] A temperature sensor is installed on the outside of the target vehicle, which can collect the atmospheric temperature outside the target vehicle in real time to obtain the atmospheric temperature outside the target vehicle.

[0081] S303, collecting the body surface temperature of pedestrians outside the target vehicle through an infrared thermal imaging system outside the vehicle.

[0082] The target vehicle is equipped with an external infrared thermal imaging system, which can collect the temperature of targets within a certain range outside the target vehicle. By identifying pedestrians in the scene, the surface temperature of pedestrians outside the target vehicle can be obtained.

[0083] Optionally, when multiple pedestrians are identified in the scene, an average of the body surface temperatures of the multiple pedestrians may be calculated to obtain the desired body surface temperature of the pedestrian outside the target vehicle.

[0084] In this embodiment, the seat temperature, atmospheric temperature and body surface temperature are collected respectively through different temperature collection devices, which can ensure the accuracy of the real-time temperature of multiple dimensions inside and outside the vehicle. Compared with the prior art method of installing a temperature sensor in the seat and then collecting the seat temperature through the temperature sensor, this embodiment does not need to control the number of temperature sensors and processor interfaces, and can collect the temperature of different parts of the seat. The infrared thermal imaging system is used to realize temperature collection, which is beneficial to reduce the burden of wiring harness layout of the target vehicle and improve the flexibility and accuracy of temperature collection.

[0085] In an exemplary embodiment, Figure 4 As shown, the above S203 includes:

[0086] S401, comparing the ambient temperature with a corresponding ambient temperature threshold.

[0087] The ambient temperature threshold includes a heating temperature threshold and a ventilation temperature threshold, and the heating temperature threshold is lower than the ventilation temperature threshold.

[0088] If the ambient temperature is lower than the heating temperature threshold in the ambient temperature threshold, execute S402; if the ambient temperature is not lower than the heating temperature threshold in the ambient temperature threshold, and the ambient temperature is not higher than the ventilation temperature threshold in the ambient temperature threshold, execute S403; if the ambient temperature is higher than the ventilation temperature threshold in the ambient temperature threshold, execute S404.

[0089] S402, heating the seat.

[0090] It can be understood that the heating temperature threshold to the ventilation temperature threshold can to a certain extent represent the temperature range that is comfortable for the user. Therefore, when the ambient temperature is lower than the heating temperature threshold, it means that the seat needs to be heated, and the seat temperature can be raised to between the heating temperature threshold and the ventilation temperature threshold.

[0091] Optionally, the heating switch used to heat the seat corresponds to multiple heating gears, such as three candidate heating gears of low, medium and high. The target heating gear can be determined from the candidate heating gears based on the difference between the ambient temperature and the heating temperature threshold, and the temperature control gear of the seat can be adjusted to the target heating gear.

[0092] Exemplarily, the target heating gear is selected according to the size of the difference. When the difference is small, the low gear is selected, when the difference is moderate, the medium gear is selected, and when the difference is large, the high gear is selected.

[0093] Optionally, multiple heating temperature thresholds corresponding to multiple candidate heating gears are set, the ambient temperature is compared with the multiple heating temperature thresholds, and then the target heating gear is determined from the multiple candidate heating gears based on the comparison result, and the temperature control gear of the seat is adjusted to the target heating gear.

[0094] S403, the seat temperature is not controlled.

[0095] In other words, when the ambient temperature is between the heating temperature threshold and the ventilation temperature threshold, it means that there is no need to control the temperature of the seat.

[0096] S404, ventilate the seat.

[0097] When the ambient temperature is higher than the ventilation temperature threshold, it means that the seat needs to be ventilated. The seat temperature of the seat can be cooled to between the heating temperature threshold and the ventilation temperature threshold.

[0098] Optionally, the ventilation switch used to ventilate the seat corresponds to multiple ventilation gears, such as three candidate ventilation gears of low, medium and high. The target ventilation gear can be determined from each candidate ventilation gear according to the difference between the ambient temperature and the ventilation temperature threshold, and the temperature control gear of the seat can be adjusted to the target ventilation gear.

[0099] Exemplarily, the target ventilation gear is selected according to the size of the difference. When the difference is small, the low gear is selected, when the difference is moderate, the medium gear is selected, and when the difference is large, the high gear is selected.

[0100] Optionally, multiple ventilation temperature thresholds corresponding to multiple candidate ventilation gears are set, the ambient temperature is compared with the multiple ventilation temperature thresholds, and then the target ventilation gear is determined from the multiple candidate ventilation gears based on the comparison result, and the temperature control gear of the seat is adjusted to the target ventilation gear.

[0101] In this embodiment, by comparing the ambient temperature with the pre-set temperature thresholds to decide whether to turn on seat heating or seat ventilation, the rationality and accuracy of temperature control can be improved. On this basis, by subdividing the pre-set temperature thresholds, further precise temperature control can be achieved to optimize the user's driving or riding experience.

[0102] In an exemplary embodiment, Figure 5 As shown, the above S203 includes:

[0103] S501, controlling the temperature of the driver's seat according to the ambient temperature.

[0104] When the associated equipment of the target vehicle is detected, the temperature of the driver's seat is controlled according to the ambient temperature.

[0105] Specifically, compare the ambient temperature with the corresponding ambient temperature threshold; if the ambient temperature is lower than the heating temperature threshold in the ambient temperature threshold, the driver's seat is heated; if the ambient temperature is higher than the ventilation temperature threshold in the ambient temperature threshold, the driver's seat is ventilated.

[0106] It is understandable that, generally, the user holding the associated device of the target vehicle is the driver. If it is uncertain whether there are other passengers in the vehicle, the temperature of the driver's seat can be controlled in advance.

[0107] S502, when a pressure change corresponding to the non-driver seat is detected by the pressure sensor, the temperature of the non-driver seat is controlled.

[0108] Among them, non-driver seats, such as the front passenger seat and the rear seats, are equipped with corresponding pressure sensors.

[0109] Furthermore, when a pressure change corresponding to the non-driver seat is detected by the pressure sensor, the temperature of the non-driver seat is controlled.

[0110] Exemplarily, when a pressure change corresponding to the front passenger seat is detected, the temperature of the front passenger seat is controlled, and when a pressure change corresponding to the rear seats is detected, the temperature of the rear seats is controlled.

[0111] Optionally, the temperature of the non-driver's seat is controlled according to the ambient temperature, or the seat temperature of the non-driver's seat is directly adjusted to be consistent with the seat temperature of the driver's seat.

[0112] In this embodiment, when the associated equipment of the target vehicle is detected, only the temperature of the driver's seat is controlled in advance, and then when it is detected that a user is sitting in the non-driver's seat, the temperature of the non-driver's seat is controlled, which can reasonably save energy.

[0113] As an optional implementation of the present embodiment, the user can set the seats and seat parts for temperature control in advance based on personal habits. For example, the user can set it to perform temperature control on the driver's seat and the passenger seat at the same time according to the ambient temperature when the associated equipment of the target vehicle is detected, or to perform temperature control on the driver's seat and the rear seats at the same time.

[0114] In this way, the above implementation can meet the actual needs of different users, make the temperature adjustment of different seats more in line with the user's subjective feelings, and further enhance the user experience.

[0115] In an exemplary embodiment, Figure 6 As shown, the seat temperature control method further includes:

[0116] S601, obtaining a historical record of temperature control of seats in a target vehicle.

[0117] The historical record of temperature control of the seats in the target vehicle refers to the historical record of the user actively adjusting the seat temperature of the seats in the target vehicle. The historical record can be stored in the memory of the target vehicle or on a server associated with the target vehicle.

[0118] Exemplarily, analyzing the historical records may yield the following information: each time the temperature of the seat in the target vehicle is automatically controlled, the user prefers to lower the seat temperature again, indicating that the seat temperature preferred by the user is lower than the normal user comfort temperature.

[0119] S602: Update the initial ambient temperature threshold according to the historical records to obtain an updated ambient temperature threshold.

[0120] Specifically, according to each seat temperature adjusted by the user in the historical records, the initial ambient temperature threshold is updated to obtain an updated ambient temperature threshold.

[0121] Exemplarily, each time the user lowers the seat temperature of the seat, the initial ambient temperature threshold may be lowered as a whole, and each time the user raises the seat temperature of the seat, the initial ambient temperature threshold may be raised as a whole.

[0122] Optionally, each time the user lowers the seat temperature of the seat, the ventilation temperature threshold in the initial ambient temperature threshold is updated according to the seat temperature lowered by the user each time, to obtain an updated ventilation temperature threshold; and each time the user raises the seat temperature of the seat, the heating temperature threshold in the initial ambient temperature threshold is updated according to the seat temperature increased by the user each time, to obtain an updated heating temperature threshold.

[0123] In this embodiment, the ambient temperature threshold is adaptively updated through the historical records of users actively adjusting the seat temperature of the seats in the target vehicle, thereby meeting the actual needs of different users, making the temperature adjustment of different seats more in line with the user's subjective feelings, and further improving the user experience.

[0124] In an exemplary embodiment, Figure 7 As shown, a seat temperature control method is provided, comprising:

[0125] S701, collecting the seat temperatures of the driver's seat and the non-driver's seat in the target vehicle through the in-vehicle infrared thermal imaging system.

[0126] S702, collecting the atmospheric temperature outside the target vehicle through a temperature sensor.

[0127] S703, collecting the body surface temperature of pedestrians outside the target vehicle through an infrared thermal imaging system outside the vehicle.

[0128] S704, performing weighted sum processing on the seat temperature, the air temperature and the body surface temperature to obtain the ambient temperature.

[0129] S705, obtaining the historical records of temperature control of the driver's seat and non-driver's seats in the target vehicle.

[0130] S706: Update the initial ambient temperature threshold according to the historical records to obtain an updated ambient temperature threshold.

[0131] S707 , when receiving the radio frequency signal sent by the key of the target vehicle, comparing the ambient temperature with the updated ambient temperature threshold.

[0132] If the ambient temperature is lower than the heating temperature threshold in the ambient temperature threshold, S708 is executed; if the ambient temperature is higher than the ventilation temperature threshold in the ambient temperature threshold, S709 is executed.

[0133] Among them, the heating temperature threshold is lower than the ventilation temperature threshold.

[0134] S708, heating the driver's seat, and heating the non-driver's seat when a pressure change corresponding to the non-driver's seat is detected by the pressure sensor.

[0135] S709, ventilate the driver's seat, and when a pressure change corresponding to the non-driver's seat is detected by the pressure sensor, ventilate the non-driver's seat.

[0136] Optionally, the heating process includes determining a target heating gear from among the candidate heating gears, and adjusting the temperature control gear of the seat to the target heating gear; the ventilation process includes determining a target ventilation gear from among the candidate ventilation gears, and adjusting the temperature control gear of the seat to the target ventilation gear.

[0137] It should be understood that, although the various steps in the flowcharts involved in the above-mentioned embodiments are displayed in sequence according to the indication of the arrows, these steps are not necessarily executed in sequence according to the order indicated by the arrows. Unless there is a clear explanation in this article, the execution of these steps does not have a strict order restriction, and these steps can be executed in other orders. Moreover, at least a part of the steps in the flowcharts involved in the above-mentioned embodiments can include multiple steps or multiple stages, and these steps or stages are not necessarily executed at the same time, but can be executed at different times, and the execution order of these steps or stages is not necessarily to be carried out in sequence, but can be executed in turn or alternately with other steps or at least a part of the steps or stages in other steps.
