In an embodiment not shown, the central control screen 4 displays information on the screen to answer the user's questions. The user answers the inquiry by touching the confirmation button on the central control screen 4.

[0053] In one embodiment of the present invention, the system further includes a seat adjustment switch, and correspondingly, the seat controller 3 further includes a switch sampling unit. The seat adjustment switch is electrically connected to the switch sampling unit. The user can perform customized control of the seat motor 5 through the seat adjustment switch. The switch sampling unit can collect the user's adjustments to the seat through the seat adjustment switch, thereby facilitating the data storage unit to store the current seat scene.

[0054] In one embodiment of the invention, the system 100 further includes a seat massage assembly mounted on the chair back. Accordingly, the seat controller 3 also includes a massage control unit. The seat controller 3 controls the seat massage assembly to massage the user's back via the massage control unit.

[0055] Another aspect of the present invention proposes an intelligent seat scene control method. (See reference...) Figure 3 This diagram illustrates a flowchart of an intelligent seat scene control method according to an embodiment of the present invention. The method includes the following steps:

[0056] The pressure signal on the seat is detected by seat sensor 1;

[0057] The user's input information is obtained through the identity recognition module 2, and the user's identity information is determined based on the input information.

[0058] The seat controller 3 determines the seat scenario to be executed based on the vehicle status information, the pressure signal, and the user identity information.

[0059] The user is asked via the central control screen 4 whether to execute the seat scene. If the user answers yes, the seat controller 3 controls the seat motor 5 to execute the seat scene.

[0060] The seating scene is one of a preset set of seating scenes.

[0061] In another embodiment of the present invention, the preset seating scene set includes

[0062] Rest mode scenario; when the vehicle status information shows that the vehicle is off and the pressure signal shows that the user is sitting in the seat, the seat scenario to be executed is determined to be the rest mode scenario. When executing the rest mode scenario, the preset rest seat position corresponding to the rest mode scenario is determined according to the user's identity information, and the seat is controlled to move to the rest seat position.

[0063] Recovery mode scenario; When the seat is in rest mode and the pressure signal indicates that the user has left the seat, the seat scenario to be executed is determined to be recovery mode scenario. When executing recovery mode scenario, a preset recovery seat position corresponding to recovery mode scenario is determined according to the user's identity information, and the seat is controlled to move to the recovery seat position.

[0064] Convenient exit scenario: When the vehicle status information shows that the vehicle is powered off and the pressure signal shows that the user has left the seat, the seat scenario to be executed is determined to be the convenient exit scenario. When executing the convenient exit scenario, the seat is controlled to move to the preset convenient exit seat position corresponding to the convenient exit mode scenario.

[0065] In another embodiment of the present invention, when the vehicle status information indicates that the vehicle is off and the pressure signal indicates that the user is sitting in the seat, a first preset time, such as three minutes, is first set via the central control screen 4. If, from the start to the end of the timer, the user neither starts the vehicle nor leaves the seat and remains leaning against the backrest, the seat scenario to be executed is determined to be the rest mode scenario, and then the user is questioned via the central control screen 4. If, during or at the end of the timer, the user leaves the seat or does not lean against the backrest, the rest mode scenario is not determined to be the seat scenario to be executed.

[0066] In another embodiment of the present invention, the preset rest mode scenario is set such that the seat back is tilted backward, the headrest is tilted synchronously with the backrest, the leg rest is opened upward, and then the seat massage is turned on.

[0067] It should be understood that the preset rest mode scenarios are not single rest mode scenarios, but rather rest mode scenarios matched to the user's identity information. In other words, when confirming the rest mode scenario to be executed, the corresponding rest mode scenario should be matched from the data storage unit based on the user's identity information for execution. This is the only way to achieve customized seat mode adjustments for different users.

[0068] In another embodiment of the present invention, the preset recovery mode scenario is generally the seat position in a normal sitting posture, that is, the initial position of the seat. It can also be preset according to user identity information.

[0069] In another embodiment of the invention, when a preset convenient exit scenario is executed, the seat controller controls the seat to move backward as a whole, leaving enough space for the driver to exit the vehicle.

[0070] In another embodiment of the invention, in the rest mode scenario, if the user has customized the seat position using the seat adjustment switch, the central control screen 4 prompts the user whether to update the rest seat position to the current seat position. If the user answers yes, the rest seat position is updated to the current seat position. That is, the next time the user needs to enter the rest mode scenario, the seat is adjusted to the updated rest seat position. In the recovery mode scenario, if the user has customized the seat position using the seat adjustment switch, the central control screen 4 prompts the user whether to update the recovery seat position to the current seat position. If the user answers yes, the recovery seat position is updated to the current seat position. That is, the next time the user needs to enter the recovery mode, the seat is adjusted to the updated recovery seat position.

[0071] It should be understood that the intelligent seat scene control system of the present invention can be installed in various vehicles, including cars, trucks, buses, hybrid vehicles, pure electric vehicles, etc. Therefore, the subject matter of this invention also aims to protect various vehicles equipped with the intelligent seat scene control system of the present invention.

[0072] It should be understood that all the above preferred embodiments are exemplary and not restrictive, and various modifications or variations made by those skilled in the art to the specific embodiments described above under the concept of the present invention should be within the legal protection scope of the present invention.
