[0043] The present invention will be described in detail below in conjunction with embodiments and the accompanying drawings. It should be noted that the described embodiments are only for facilitating the understanding of the present invention and do not impose any limitation on it.

[0044] Virtual touch technology means that within the visible range, there are no conventional operation button markings visible. The touch area is perfectly integrated with the original interior trim, designed and installed in a position accessible to the user. Only a very small area and function markings are required. The user can complete the control of various electrical devices in the car only by gestures such as clicking, double-clicking, finger sliding, and gently pressing. The operation rules are simple and direct, without the need for additional training or even referring to the instruction manual.

[0045] The application of virtual touch technology greatly improves the beauty and integrity of the car interior, and can bring users a novel, surprising and comfortable feeling.

[0046] This embodiment provides a method for adjusting a car seat, as Figure 1 shown, the method includes:

[0047] Step 101, obtaining capacitance data detected by a pressing detection capacitor;

[0048] Step 102, determining whether to activate a gesture recognition capacitor according to the capacitance data detected by the pressing detection capacitor;

[0049] In one embodiment, if the capacitance data detected by the pressing detection capacitor is not equal to a preset threshold, it is determined to activate the gesture recognition capacitor;

[0050] In one embodiment, if the capacitance data detected by the pressing detection capacitor is equal to the preset threshold, it is determined not to activate the gesture recognition capacitor.

[0051] Among them, the preset threshold can be set to 0, and its specific value can be set according to needs. This embodiment is only illustrated by taking 0 as an example.

[0052] This embodiment detects the capacitance data of the pressing detection capacitor and compares the capacitance data with the preset threshold 0 to suppress false operations caused by various interferences.

[0053] Step 103, obtaining capacitance data detected by the gesture recognition capacitor;

[0054] Step 104, generating a control instruction according to the capacitance data detected by the gesture recognition capacitor; wherein, the control instruction is used to instruct the controller to control the car seat to move forward and backward and / or adjust the backrest angle.

[0055] In one embodiment, generating a control instruction based on the capacitance data detected by the gesture recognition capacitor includes:

[0056] Obtain the gesture action category, where the gesture action category includes at least one of finger up, down, left, right, or 45° sliding;

[0057] Generate the capacitance data detected by the gesture recognition capacitor according to the gesture action category;

[0058] Generate a control instruction based on the capacitance data detected by the gesture recognition capacitor.

[0060] Figure 3 A system for adjusting a vehicle seat provided by an embodiment of the present invention, as Figure 3 shown, the system includes:

[0061] A data processor 301, and a press detection capacitor 302, a gesture recognition capacitor 303, and a controller 304 all connected to the data processor;

[0062] wherein, the press detection capacitor 302 is configured to detect a user's pressing action;

[0063] The gesture recognition capacitor 303 is configured to detect a user's gesture action category;

[0064] The data processor 301 is configured to acquire the capacitance data detected by the press detection capacitor 301; and determine whether to activate the gesture recognition capacitor 303 according to the capacitance data detected by the press detection capacitor 301; and acquire the capacitance data detected by the gesture recognition capacitor 303; and generate a control instruction according to the capacitance data detected by the gesture recognition capacitor;

[0065] The controller 304 is configured to control the vehicle seat to move forward and backward and / or adjust the backrest angle.

[0066] Among them, the data processor 301 is connected to the pressing detection capacitor 302, the gesture recognition capacitor 303, and the controller 304, all of which are connected through a BCM or LIN bus.

[0067] In one embodiment, the pressing detection capacitor and the gesture recognition capacitor form a touch sensor. As Figure 4 shown, the touch sensor sequentially includes a gesture recognition electrode layer 401, a first flexible substrate layer 402, a first shielding layer 403, an elastic isolation layer 404, a pressing electrode layer 405, a second flexible substrate layer 406, and a second shielding layer 407 from top to bottom; among them, a plurality of gesture recognition electrodes are arranged on the gesture recognition electrode layer 401.

[0068] It should be noted that both the first shielding layer 403 and the second shielding layer 407 are shielded by grounding.

[0069] When the user sits on the seat and presses the detection area on the side of the seat with a finger, as Figure 5 shown, the touch sensor deforms, the distance between the first shielding layer 403 and the pressing electrode layer 405 changes, thereby causing a change in the capacitance value of the pressing detection capacitor, so as to detect the user's pressing action, and then activate the gesture recognition capacitor, and thereafter the user's gesture can be detected.

These four arc electrodes can compensate for the square dot matrix electrodes and maintain the recognition action.

[0072] The present invention has a pressing detection function and a gesture detection function. Without damaging the appearance of the seat, it provides a simple and flexible seat control mode for users, allowing users to control the front-back, height, and backrest angle adjustment of the seat easily and comfortably, bringing unexpected surprises to users.

Since the improvement only relates to the system for adjusting the car seat on the seat, and other components can all adopt relatively mature technologies in the prior art. Therefore, the present application will not describe other components of the seat anymore.

[0074] Another aspect of the present application also relates to an automobile including the above-mentioned seat. Since the improvement only relates to the seat on the automobile, and other components can all adopt relatively mature technologies in the prior art.

Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the essence and scope of the technical solutions of the present invention.
