[0040] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0041] Figure 1 This is a flow chart of a seat control method disclosed in an embodiment of the present application. Figure 1 As shown, the seat control method may include:

[0042] Step 101: Obtain driving information of a vehicle, wherein the driving information represents the current driving condition of the vehicle or the driving condition of the vehicle in the future.

[0043] The driving information may be information of a single category, or may include information of different categories representing different meanings. For example, the driving information may be vehicle continuous driving time, continuous driving mileage, navigation distance information, etc.

[0044] The driving information can be automatically detected and obtained by the vehicle computer system, such as a sensor installed near the vehicle tire detects the continuous driving mileage of the vehicle after it is powered on and transmits it to the vehicle computer; or, the driving information can also be provided by an external device, such as the vehicle computer can obtain navigation data from the user's mobile phone.

[0045] Step 102: If the driving information meets the first condition, the seat is controlled to enter a first working mode, and the first working mode is used to help the driver improve driving comfort.

[0046] When the data contained in the driving information is different, the first condition is also different; when the driving information meets the first condition, the vehicle's central control system can control the seat to enter the first working mode by issuing instructions, and start functions matching the first working mode, such as seat massage function, seat ventilation function, etc., thereby helping the driver relieve driving fatigue and optimize the driving experience.

[0047] The first working mode is only one working mode of the seat. In actual applications, the seat may have other working modes. The seat functions and gears enabled by different working modes have default values. Of course, the default values ​​can also be adjusted in the application scenario based on the user's preferences and habits. For example, the functions activated by the seat in the first working mode include seat ventilation and seat massage. In other working modes, the seat can also activate seat heating, seat shock absorption, etc.

[0048] As the technical personnel in the field know, most of the seats in commercial vehicles are airbag seats, which are basically independent systems and do not interact with other modules in the vehicle. The usage scenarios are relatively simple. The driver needs to adjust the physical switches on the seat to start ventilation, heating and other functions. However, this manual control method will distract the driver's attention and affect driving safety.

[0049] The seat control method disclosed in the embodiment of the present application can automatically obtain driving information during implementation, and automatically control the seat to enter the first working mode when it meets specific conditions. No driver intervention is required during the process, allowing users to experience more intelligent seat control.

[0050] In one implementation, the driving information represents the continuous driving condition of the first driver. If the driving information meets the first condition, controlling the seat to enter the first working mode may include: if the continuous driving data of the first driver reaches a set threshold, controlling the seat to enter the first working mode.

[0051] For example, if the continuous driving data includes mileage, then when the continuous driving mileage of the vehicle after the last power-on exceeds a set mileage threshold, the seat can be controlled to enter the first working mode. Alternatively, if the continuous driving data includes driving time, then when the continuous time after the vehicle is powered on exceeds a set time threshold, the seat can be controlled to enter the first working mode.

[0052] Of course, the continuous driving data is detection data for the same driver. If the vehicle stops briefly during driving and the driver is replaced, the continuous driving data is reset and the continuous driving data for the newly replaced driver is recorded again. Based on this, in other implementations, the method may also include: if a driver data change is detected, the continuous driving data is reset and recalculated.

[0053] The driver data may be the driver's weight data obtained by seat detection, or the driver's facial image obtained by a camera. In implementation, it may be possible to identify and determine whether the driver has changed based on the weight data, the driver's facial image, or other possible data.

[0054] In this embodiment, continuous driving data is used as the judgment condition for controlling the seat to enter the first working mode. When the driver's continuous driving time or mileage reaches a set value, the seat can be automatically controlled to work. Massage, seat ventilation and other functions can be started according to the settings to help relieve the driver's fatigue and discomfort.

[0055] In another implementation, the driving information includes navigation road condition information, and the driving information satisfies the first condition, and the seat is controlled to enter the first working mode, which may include: if the navigation road condition information indicates that there will be a traffic congestion section in the future, the seat is controlled to enter the first working mode in the first period before entering the traffic congestion section or after entering the traffic congestion section.

[0056] Many vehicles use the vehicle system or terminal equipment for navigation before or during a trip. The navigation route usually displays traffic congestion conditions. For example, a red section indicates traffic congestion, and a green section indicates a smooth road. Before entering a congested section, a time can be set, such as the first 2 minutes, or when just entering a congested section, the seat can be controlled to enter the first working mode.

[0057] In practice, the driver can set the navigation through the vehicle's central control screen, and the central control screen will start the automatic ventilation and automatic massage functions according to the internal algorithm to relieve the driver's driving fatigue. For example, if the navigation recognizes a traffic jam, the vehicle system (body controller) can automatically start seat massage and seat ventilation in advance according to the traffic jam situation to increase the driver's comfort experience.

[0058] In the event of traffic congestion, the seat is controlled to enter the first working mode, which not only improves the driver's driving comfort, but also alleviates the driver's irritability caused by the congestion.

[0059] In one implementation, the seat control method may further include: if the vehicle stops driving for a period of time exceeding a first period of time without being powered off, the driving information is reset and recalculated.

[0060] If the vehicle stops while driving, but the vehicle is not powered off, and the length of time the vehicle stops exceeds the first length of time, it can be considered that the driver has rested for a period of time, and the driving information can be reset and recalculated. For example, the driver drives on the highway for a period of time, stops at a service area and rests for a period of time, and when the vehicle starts driving again, the driving information will be recorded or detected again. For another example, the vehicle stops from a driving state, the door is open, and the seat is occupied. It is determined that the driver has left the vehicle. If the seat is still occupied within 3 minutes, it is determined that the person has left the vehicle, the mileage is reset, the vehicle starts again, and the mileage is recorded again.

[0061] Alternatively, if the vehicle stops moving, the door is open, and the seat is occupied, it is determined that the driver has left the vehicle. If the seat is still occupied within the set time, it is determined that the person has left the vehicle, the mileage is reset, the vehicle is driven again, and the relevant data is recorded again.

[0062] Alternatively, if the vehicle is powered off, the driving information used in the present application solution is reset, and the driving information is recorded again when the vehicle is powered on next time.

[0063] In another implementation, the seat control method may also include: obtaining a facial image of the driver; analyzing and processing the facial image; if the result of the analysis and processing meets a second condition, controlling the seat to enter a first working mode, wherein the second condition indicates that the driver has set facial features or facial movements.

[0064] The facial features or facial movements include the driver yawning several times, half-squinting eyes, frequent blinking, etc. When the fatigue driving camera, that is, the camera that takes the facial image of the person in the driver's seat, takes the driver's facial image, it can visually identify the driver's fatigue level and send it to the body controller. The body controller intelligently turns on the seat ventilation and seat massage functions according to the algorithm to relieve the driver's driving fatigue.

[0065] In another implementation, the seat control method may further include: obtaining temperature auxiliary information, wherein the temperature auxiliary information represents the ambient temperature; if the temperature auxiliary information satisfies a third condition, controlling the seat to enter a second working mode, wherein the second working mode is used to adjust the seat temperature so that the seat temperature is close to a set temperature.

[0066] The third condition may be that the ambient temperature is higher than a high temperature setting value or lower than a low temperature setting value.

[0067] For example, the sunlight sensor can identify the surrounding environment. If the ambient temperature is lower than the set threshold, the vehicle has not entered into functional restrictions, and the battery SOC (State of Charge) is normal, the seat heating function is intelligently turned on, and the seat temperature can be adjusted steplessly with the ambient temperature. If the ambient temperature is higher than the set threshold, the vehicle has not entered into functional restrictions, and the battery SOC is normal, the seat ventilation function is intelligently turned on, and the seat ventilation air volume can be adjusted steplessly with the changes in the surrounding environment.

[0068] For example, when the defrost function of the vehicle's air-conditioning system is turned on and the ambient temperature is confirmed to be relatively low, the body controller can intelligently turn on the seat heating function through internal logic.

[0069] In other implementations, the communication module on the vehicle, such as T-BOX, can also intelligently push the user whether to turn on the seat ventilation or heating function based on weather information; when the user turns on the air conditioner remotely, the seat ventilation or heating function is also turned on synchronously. Users can also turn on the seat ventilation or heating at a scheduled time, so that the seats of urban service vehicles can reach a comfortable state before using the vehicle every day.

[0070] In other implementations, the seat working state can also be intelligently controlled according to the degree of vehicle bumps. For example, the body controller collects the vehicle acceleration based on the body acceleration sensor (because the vehicle is driving on a bumpy road, the longitudinal acceleration can identify the degree of bumps). Through the internal algorithm, after reaching a certain threshold, the seat shock-absorbing airbags and damping shock absorbers are intelligently adjusted to intelligently optimize the seat's shock-absorbing effect.

[0071] In other implementations, when it is detected that the door is opened, the body controller can control the seat to enter other operating modes, such as controlling the shock absorber, airbag and motor inside the seat to adjust the seat to a state suitable for the driver to get off the vehicle.

[0072] Based on the contents introduced in the above embodiments, in the present application scheme, the vehicle system (body controller) integrates the seat control function, which can save multiple small control modules that originally controlled the various functions of the seat independently, such as massage modules, equivalent modules, heating modules, etc.; that is, the seat function is integrated into the body controller, the number of modules in the whole vehicle is reduced, and the vehicle cost is effectively reduced; in addition, the scheme can automatically adjust the seat working mode based on the vehicle usage scenario according to the set algorithm, thereby improving the user's driving experience.
