Description

Technical Field

[0001] The present disclosure relates to the field of intelligent automobile technology, and in particular to a system and method for automatically adjusting the position of a driver's seat, a readable storage medium and an automobile. Background Art

[0002] As automobile control becomes more intelligent, the driver's seat, as an important part of car driving, also needs to be adjusted intelligently to provide the driver with a more convenient, effective and comfortable experience.

[0003] There are generally two methods for adjusting the main driver's seat of a car. One is the traditional manual adjustment, which uses the hard buttons of the seat to adjust the front and rear upper and lower backrest positions of the seat. Although this traditional manual adjustment method meets the needs of the driver to adjust the seat position when driving a car to a certain extent, due to the mechanical nature of this operation, once different people drive the same vehicle, they still need to make large manual adjustments, which not only wastes time and reduces the convenience and comfort of driving, but also reduces the service life of the buttons due to repetitive seat adjustment operations. Another adjustment method is to use the car memory adjustment function to automatically adjust the seat. This method first requires the driver to have his own dedicated account to log in to the big screen. After logging in to the dedicated account, the big screen will send the memory position to the seat, and then adjust it to the position saved by the driver. This method is not suitable for the driver's first use of the vehicle. The driver needs to have a big screen account and use the traditional manual adjustment of the seat position, and then save it to the driver's account before it can be used. When the driver drives the vehicle for the first time, this function cannot be used, and the traditional manual adjustment method of the seat can only be used, which affects the user experience. Summary of the invention

[0039] The present disclosure is described below in conjunction with the accompanying drawings. The preferred embodiments described herein are only used to illustrate and explain the present disclosure and are not used to limit the present disclosure.

[0040] The present disclosure provides a system for automatically adjusting the position of a driver's seat, comprising:

[0041] Electric seats, DMS cameras, central processing units and central storage units; among them,

[0042] The central processing unit is configured as follows:

[0043] Receiving the user's eye position collected by the DMS camera;

[0044] receiving a reference user eye position stored in the central storage unit;

[0045] A seat adjustment amount is calculated based on the user eye position and a reference user eye position, and the electric seat is adjusted according to the seat adjustment amount.

[0046] Furthermore, the DMS camera is arranged in the A-pillar of the automobile.

[0047] Further, the system further comprises: a seat belt status detection unit;

[0048] The central processing unit is configured as follows:

[0049] The seat belt status detection unit is used to determine whether the seat belt is fastened. If so, the electric seat is adjusted based on the user's eye position captured by the DMS camera; if not, the electric seat is not adjusted.

[0050] According to some embodiments of the present disclosure, the main driver's seat position automatic adjustment system includes: a main driver's electric seat system, a DMS camera, a central storage unit, a central processing unit, and a seat belt status detection unit. The DMS camera is used to capture the current eye position of the driver, and the central processing unit is used to calculate the distance that the seat needs to be adjusted based on the current eye position of the driver captured by the DMS camera and the reference eye position pre-stored in the central storage unit, and control the front and back, up and down movement of the seat, and the backrest movement to adjust the eye position to a suitable range. In this embodiment, the driver's eye information is captured by the DMS camera, and the front and back, up and down movement of the seat are controlled based on the current eye position of the driver captured by the DMS camera and the reference eye position pre-stored in the central storage unit, providing the driver with a more convenient, effective and comfortable experience. In addition, the main driver's seat position automatic adjustment system provided by the present disclosure does not consider the driver's identity but the driver's eye position, which can meet the scenario where there are multiple drivers in the same car.

[0051] Furthermore, the system further comprises: a human-computer interaction module;

[0052] The central processing unit is configured as follows:

[0053] Receiving user operation instructions through the human-computer interaction module;

[0054] Determine whether to adjust the electric seat based on the user's eye position captured by the DMS camera according to the user operation instruction.

[0055] Furthermore, the central processing unit is configured as follows:

[0056] A reminder is sent to the user through the human-computer interaction module and a timer is performed. When the timer expires and the user does not respond to the reminder, the electric seat is adjusted based on the user's eye position captured by the DMS camera.

[0057] Furthermore, the central processing unit is configured as follows:

[0058] A reminder is sent to the user through the human-computer interaction module and timing is performed. If the timing has not ended and the user responds to the reminder, an electric seat adjustment strategy is determined based on the user operation instruction and the electric seat is adjusted.

[0059] According to other embodiments of the present disclosure, Figure 1As shown, the automatic adjustment system for the main driver's seat position also includes: a human-computer interaction module (in some embodiments, a large screen on the vehicle). The central processing unit determines that the driver is about to drive the vehicle to start according to the driver starting the vehicle and fastening the seat belt (the lock signal sent by the seat belt status detection unit). When it is detected that the seat position needs to be adjusted, the detected result is sent to the large screen on the vehicle. The large screen will start a voice broadcast: Please maintain the driving posture, the seat position will be adjusted for you soon, and the large screen will count down for 3 seconds after the reminder; after 3 seconds, the large screen will send a signal to the central processing unit, and the central processing unit will call the reference eye position in the central storage unit, compare the reference eye position with the driver's current eye position obtained by the DMS camera, calculate the coordinates that the seat needs to move after comparison, and then send the calculated coordinate information to the main driver's electric seat system. After receiving the coordinate information, the main driver's electric seat system automatically adjusts the seat.

[0060] Further, the central processing unit calculates the seat adjustment amount based on the user's eye position and the reference user's eye position, and the execution method includes:

[0061] Establish a three-dimensional coordinate system with the DMS camera as the origin;

[0062] Determining eye position coordinates of the user based on the DMS camera;

[0063] The seat adjustment amount is calculated according to the collected eye position coordinates and the reference eye position coordinate range interval stored in the central processing unit.

[0064] According to some embodiments of the present disclosure, Figure 2As shown, the process of the central processing unit calculating the seat adjustment amount based on the user's eye position and the reference user's eye position is as follows: a first DMS camera embedded in the A-pillar of the car and with the lens facing the driver is taken as the origin, the vehicle length direction is the X-axis, the vehicle width direction is the Y-axis, and the vehicle height direction is the Z-axis to establish a three-dimensional coordinate, the midpoint of the line connecting the pupils of both eyes is the current driver's eye position (X0, Y0, Z0), the reference eye position is the spherical part of the figure below, and the coordinate range is Xm, Ym, Zm~Xn, Yn, Zn. The eye position captured by the first DMS camera is compared with the eye reference position of the driver when driving the car stored in the central memory in advance. When the current driver's sitting posture is offset from the reference position, the driver's current eye position will be inconsistent with the reference eye. At this time, a confirmation pop-up box will pop up on the large screen with a countdown of 5 seconds. If the owner does not make a choice, the automatic adjustment of the main driver's electric seat will be selected by default. If the owner chooses to cancel the adjustment, the electric seat will not be adjusted; when the current driver's sitting position is within the reference position range, the main driver's electric seat will not be adjusted. Taking the driver's current eye position as the capture reference, the eye position coordinates of the driver's current eye position relative to the reference coordinates are determined, and the offset between the eye position coordinates and the pre-stored eye reference position range of the driver when driving the car is analyzed and calculated. The front and rear, up and down, and backrest distances that the seat needs to move are calculated based on the offset, and the moving distance is converted into a control signal to control the seat movement so that the seat position adapts to the driver's needs.

[0065] Based on the same technical concept, the present disclosure also proposes a method for automatically adjusting the position of a driver's seat based on the above-mentioned automatic adjustment system for the position of a driver's seat, comprising:

[0066] Using the central processing unit, the following method is executed:

[0067] Receiving the user's eye position collected by the DMS camera;

[0068] receiving a reference user eye position stored in the central storage unit;

[0069] A seat adjustment amount is calculated based on the user eye position and a reference user eye position, and the electric seat is adjusted according to the seat adjustment amount.

[0070] like Figure 3 As shown, the present disclosure also proposes a computer-readable storage medium, in which a computer program or instruction is stored. When the computer program or instruction is executed by a processor, it is at least used to implement the above-mentioned method for automatically adjusting the position of the driver's seat.

[0071] Based on the same technical concept, the present disclosure also proposes a car, which is equipped with the above-mentioned automatic driver seat position adjustment system.
