Description

Technical Field

[0001] The present invention relates to the technical field of front electric slide rails, and more specifically, to a front electric slide rail for intelligent adjustment of vehicle seats. Background Art

[0002] In the existing vehicle seat adjustment technology, traditional manual adjustment methods have problems such as cumbersome operation and low adjustment accuracy. At the same time, the seat posture cannot be automatically adjusted according to the user's physical characteristics and driving habit information. Therefore, in order to meet the requirements of users for comfort and convenience, intelligent adjustment of the front electric slide rail of the vehicle seat is required.

[0003] For example, the patent with the Chinese patent publication number CN115946583B discloses an electric slide rail for long-distance intelligent adjustment of vehicle seats. The present invention collects the manual adjustment curves of long-distance adjustment during daily adjustment, then matches and corresponds the manual adjustment curves with the corresponding users, thereby constructing basic quantitative data to match different users. Then, the data of the corresponding users are screened to eliminate abnormal data, and at the same time, the manual adjustment curves are extracted and respectively constructed to generate a screening excellent set corresponding to the users. By accumulating the screening excellent sets of a large number of manual adjustment curves, multiple intelligent adjustment curves are generated to correspond to different users, thereby constructing and generating a dynamic matching set. When the user uses it again, the intelligent adjustment curve corresponding to it is automatically retrieved through the matching of recognition features, and the movement of the induction slide rail unit is automatically controlled to achieve intelligent space regulation to match the needs of different users.

[0004] For example, the patent with the Chinese patent publication number CN106985709A discloses an intelligent adjustment device, system and method for vehicle seats, including: a positioning unit that calculates the position information of each seat occupant according to the wireless signal of the wearable device; an identity recognition unit that obtains the user's identity information through the wearable device and obtains the seat parameters corresponding to the user in the storage unit according to the recognized identity information and the obtained position information; a storage unit that memorizes and stores the identity information of several users and their corresponding seat parameters; an adjustment control unit that adjusts the corresponding seat according to the seat parameters obtained by the identity recognition unit. The present invention realizes the intelligent adjustment of vehicle seats by using the wearable device to intelligently identify the user's identity and the user's position in the vehicle.

[0005] The following problems also exist in the above prior art: 1. Users who have driven the target vehicle and those who have not are not classified and discussed, and the classification discussion of the front electric slide rail adjustment of the car seat is not carried out according to these two driving situations. For users who have driven the target vehicle, it increases the cumbersome operation of users manually adjusting the seat. For users who have not driven the target vehicle, it cannot provide convenience for different users and reduces the driving comfort of users.

[0006] 2. For users who have not driven the target vehicle, before entering the vehicle, the front electric slide rail is not adjusted according to the user's physical characteristics, resulting in the position of the seat when entering the vehicle may not meet the comfort requirements of the user.

[0007] 3. For users who have not driven the target vehicle, before driving, the front electric slide rail is not adjusted according to the angle between the user's instep and the pedal plane and the knee bending angle. Users may face the problem of unsmooth pedal operation, reducing the response speed and accuracy of the operation. At the same time, an inappropriate knee bending angle will limit the operation flexibility of the legs, thus posing a threat to driving safety and reducing the driving safety of users.

[0052] It should be noted that the images between the non-experienced user's foot and the pedal and between the thigh and the calf before the current driving are captured by high-definition cameras installed near the pedal and around the seat inside the target vehicle.

[0053] In a specific embodiment of the present invention, the specific process of analyzing the angle between the instep plane of the non-experienced user before the current driving and the pedal plane is as follows: D1. Based on the image between the non-experienced user's foot and the pedal before the current driving, with the center of the pedal as the origin, the length direction of the pedal as the axis, and the width direction as the axis, a two-dimensional plane of the pedal plane is constructed.

These sensors can sense the pressure magnitudes at different positions of the pedal. When the foot steps on the pedal, the pressure sensors will output a pressure distribution matrix. 2) Pressure center calculation: By processing the data of the pressure sensor array, calculate the position of the pressure center. For example, for a pressure sensor array, the position of each sensor is known, and the pressure value is , then the abscissa of the pressure center can be calculated by , and the ordinate is obtained in the same way. 3) Pressure direction vector determination: The pressure direction vector can be approximated as the vector pointing from the pressure center to the geometric center of the pedal. According to the position coordinates of the geometric center of the pedal and the position coordinates of the pressure center, the representation of the pressure direction vector in the pedal plane coordinate system can be obtained. After normalization, the unit pressure direction vector can be obtained.

[0062] It should be noted that the ideal angle range between the instep and the pedal plane is usually between 90 - 120 degrees, and the ideal knee bending angle range is more suitable at about 100 - 130 degrees.

[0063] F2. Extract the appropriate moving distance of the front electric slide rail corresponding to the unit angle deviation from the database. 。

[0064] F3. If , it indicates that the front electric slide rail of the target vehicle does not need to move for the non-experienced user before the current driving.

[0069] F8. If , determine the moving state of the front electric slide rail of the target vehicle before the current driving by non-experienced users according to the specific deviation degree.

[0070] In a specific embodiment of the present invention, the specific process of determining the moving state of the front electric slide rail of the target vehicle before the current driving by non-experienced users according to the specific deviation degree is as follows: G1. When , calculate the degree of deviation of the angle between the instep and the pedal plane of the non-experienced user before the current driving from the ideal range , , calculate the degree of deviation of the knee bending angle of the non-experienced user before the current driving from the ideal range , , if , move the front electric slide rail of the target vehicle backward by distance, if , move the front electric slide rail of the target vehicle forward by distance.

[0071] G2. When , if , move the front electric slide rail of the target vehicle forward by distance, if , move the front electric slide rail of the target vehicle backward by distance.

[0072] It should be noted that when one angle needs to move forward and the other angle needs to move backward, temporarily ignore the one with a smaller deviation degree, because the larger deviation angle has a more serious impact on the driver's comfort and operation convenience.

[0073] By adjusting the front electric slide rail according to the angle between the instep and the pedal plane and the knee bending angle of the user who has driven the target vehicle before driving, the embodiment of the present invention avoids the problem of unsmooth pedal operation for users, improves the response speed and accuracy of operation, and at the same time avoids that an inappropriate knee bending angle will limit the operation flexibility of the legs, thus avoiding threatening driving safety and improving the driving safety of users.
