Description

Technical Field

[0001] The present invention relates to the technical field of smart cockpits, and in particular to a smart cockpit adjustment system. Background Art

[0002] Smart cockpit systems are maturing in the automotive market. Modern car cockpits have evolved from simple driving spaces into an extension of intelligent interaction and living environments. With the widespread adoption of autonomous driving technology, cockpit design will prioritize comfort, entertainment, and personalization, becoming a "third living space." Prior art smart cockpit adjustment systems, such as the invention patent application number 202111677901.0, entitled "Intelligent Cockpit Multi-Mode Operation Adjustment System, Method, Cockpit, and Vehicle," disclose a cockpit adjustment system comprising a cockpit system control module, an ACC activation module connected to the cockpit system control module for powering the cockpit, several seat control modules connected to the cockpit system control module, several shoebox control modules connected to the cockpit system control module, and a touchscreen control screen connected to the cockpit system control module. This invention achieves space constraints within the cabin for seating and shoeboxes, allowing passengers to relax their entire body, including their feet, within a limited space. This system offers strong versatility and practicality. However, the smart cockpits in the existing technology have drawbacks in the intelligent adjustment of seats during use. The seat adjustment cannot be humanized and fully automated, especially in terms of the mutual coordination between seats and seat belts to improve the safety of passengers in emergency situations. Summary of the Invention

[0003] In response to the above problems, the main purpose of the present invention is to provide an intelligent cockpit adjustment system that can store the driving habits of different drivers during the driving process, set the seat adjustment mode based on the driving habits, and cooperate with the seat and seat belt to improve protection safety in emergency situations.

[0004] In order to achieve the above-mentioned objectives, the present invention provides an intelligent cockpit adjustment system, including a seat control system, a seat belt control system, a sensing system, an information acquisition system and a data processing system, wherein the seat control system includes a seat adjustment module and a backrest adjustment module, the seat adjustment module is used to adjust the front and rear position of the seat, and the backrest adjustment module is used to adjust the angle between the backrest and the seat; the seat belt control system includes a seat belt locking module, and the seat belt locking module is used to control the seat belt; the sensing system includes a pressure sensor and an acceleration sensor, the pressure sensor is located on the seat and the backrest, and the acceleration sensor is located outside the intelligent cockpit; the information acquisition system includes a face acquisition module and an image information processing module; the data processing system includes a data collection module, a data processing module, an information database module and a controller.

[0005] Furthermore, the face acquisition module is used to collect facial information of people sitting in seats in the cabin and transmit it to the image information processing module. The image information processing module processes the collected multiple frames of images to obtain clear facial images and transmits them to the data collection module. The data collection module can detect whether there is duplicate image information. If so, it will be automatically deleted. If not, it will be automatically saved to the information library module.

[0006] Furthermore, the seat control system and the seat belt control system are connected to the controller signal. The pressure sensor is used to detect the pressure value on the seat or backrest and send the pressure value signal to the data collection module. The acceleration sensor is used to detect the acceleration value of the smart cockpit as a whole structure, and its acceleration value signal is sent to the data collection module.

[0007] Furthermore, after the data collection module receives the pressure value signal from the pressure sensor, it is transmitted to the data processing module. The data processing module first filters the pressure value, filters out the scattered values ​​that are interrupted or obviously deviated, and obtains the final pressure value.

[0008] Furthermore, the filtered pressure values ​​are plotted in a curve graph with time as the x-axis and pressure value as the y-axis. The obtained curve graph is then divided into several curve segments along the x-axis direction with time t as the unit. The median pressure value of each curve segment is calculated, and the average value of the obtained median values ​​is obtained as the pressure average value f. Two standard lines are then drawn, and the pressure values ​​of the standard lines are f+0.1f and f-0.1f respectively.

[0009] Furthermore, the real-time pressure curve and two standard lines are displayed in the pressure curve graph, and the graph is automatically stored in the information library module. When the pressure value of the real-time pressure curve deviates from the two standard lines for n consecutive units t, and at the same time the information obtained by the face acquisition module is not zero, the data processing module sends a seat adjustment signal to the controller, and the controller sends a start signal to the seat control system.

[0010] Furthermore, the seat adjustment module and the backrest adjustment module of the seat control system simultaneously send adjustment signals to adjust the seat forward and backward, up and down, and rotate the backrest toward the passenger until the pressure values ​​obtained by the pressure sensors on the seat and backrest are within the range of f-0.1f to f+0.1f, and then the adjustment is stopped.

[0011] Furthermore, the facial information in the information library module and the pressure curve graph obtained after the current facial information is collected and before the next facial information is collected are stored as a whole unit.

[0012] Furthermore, the data collection module also receives the acceleration voltage signal from the acceleration sensor and transmits it to the data processing module. After the same processing by the data processing module, an acceleration curve graph is obtained. When the real-time acceleration in the curve graph deviates from the two standard lines, the data processing module sends a seat belt adjustment signal and a seat adjustment signal to the controller, and the controller controls the seat and backrest to fit tightly against the occupant, and at the same time the seat belt is locked.

[0013] Furthermore, the seat control system also includes an adjustable lumbar support, which is located in the front of the seat. The adjustable lumbar support is also provided with a pressure sensor. The adjustable lumbar support can be adjusted forward and backward through the controller. The pressure value of the pressure sensor is sent to the data collection module. When the pressure value of the pressure sensor exceeds the set pressure value p0, the data collection module sends a signal to the controller, and the controller adjusts the position of the adjustable lumbar support until the pressure value of the pressure sensor is within the range of p0-0.1p0 to p0+0.1p0, and the controller stops adjusting.

[0014] Through the above technical solution, the beneficial effects of the present invention include:

[0015] (1) The seat control system of the present invention is provided with a seat adjustment module and a backrest adjustment module. The pressure value is obtained through a sensing system. When the pressure value exceeds the average value range, the controller transmits an adjustment signal to adjust the seat or backrest. Unlike the ordinary adjustment mode, the pressure value obtained in the present invention is processed and the average value range is obtained through image processing to reduce the adjustment error and improve the accuracy.

[0016] (2) In addition, the intelligent cockpit adjustment system of the present invention is also provided with a face collection module. By collecting the facial information of the passengers, the corresponding seat operation degree can be obtained to improve the seat adaptability. In addition, the adjustment system of the present invention can also record the driver's driving habits, mainly focusing on the acceleration during the driving process of the car, so as to obtain the driving habits of the driver, and set the acceleration range value on this basis. When it is out of the range for a certain period of time, the intelligent cockpit protection mode can be activated, that is, the seat control system and the seat belt control system are activated at the same time to improve the safety of the passengers.

[0026] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] like Figure 1 As shown, the present invention provides an intelligent cockpit adjustment system, including a seat control system, a seat belt control system, a sensing system, an information acquisition system and a data processing system, wherein the seat control system is provided with a seat adjustment module and a backrest adjustment module, the seat adjustment module is used to adjust the front and rear position of the seat, and the backrest adjustment module is used to adjust the angle between the backrest and the seat; the seat belt control system is provided with a seat belt locking module, and the seat belt locking module is used to control the seat belt; the sensing system is provided with a pressure sensor and an acceleration sensor, and the number of the pressure sensor and the speed sensor is multiple, the pressure sensor is located on the seat and the backrest, and the acceleration sensor is located outside the intelligent cockpit; the information acquisition system includes a face acquisition module and an image information processing module; the data processing system includes a data collection module, a data processing module, an information library module and a controller.

[0028] The face acquisition module in the present invention is used to collect facial information of people sitting in seats in the cabin, and then transmit it to the image information processing module. The image information processing module processes the collected multiple frames of facial images to obtain clear facial images, and then transmits them to the data collection module. The data collection module can determine whether there is duplicate image information. If so, the facial image is automatically deleted. If not, the facial image is automatically saved to the information library module. When the data collection module determines whether it is duplicate facial image information, it compares it with the facial image stored in the information library module.

[0029] Furthermore, the seat control system and the seat belt control system of the present invention are connected to the controller signal, the pressure sensor is used to detect the pressure values ​​at various positions on the seat and the backrest, and send the pressure value signal to the data collection module, and the acceleration sensor is used to detect the acceleration value of the smart cockpit as a whole structure, and its acceleration value signal is sent to the data collection module.

[0030] Furthermore, after the data collection module of the present invention receives the pressure value signal of the pressure sensor, it is transmitted to the data processing module. The data processing module first filters the pressure value, filters out the scattered values ​​that are interrupted or obviously deviated, and obtains the final pressure value. Then, the filtered pressure value is plotted as a curve, such as Figure 2 As shown, time is plotted as the x-axis and pressure value as the y-axis, and then the obtained curve is divided into several curve segments along the x-axis direction with time t as the unit, the pressure median value of each curve segment is calculated, and the average value of the obtained median values ​​is obtained as the pressure average value f, and two standard lines are drawn, and the pressure values ​​of the standard lines are f+0.1f and f-0.1f respectively.

[0031] Furthermore, the pressure curve graph of the present invention displays a real-time pressure curve [f(t)] and two standard lines (f+0.1f and f-0.1f, respectively). The graph is automatically stored in the information library module. When the pressure value f(x) of the real-time pressure curve deviates from the two standard lines for n consecutive units t, and at the same time, the information obtained by the face acquisition module is not zero, the data processing module sends a seat adjustment signal to the controller, and the controller sends a start signal to the seat control system.

[0032] Furthermore, the seat adjustment module and the backrest adjustment module of the seat control system of the present invention simultaneously send adjustment signals to adjust the seat forward and backward, up and down, and rotate the backrest toward the passenger until the pressure values ​​obtained by the pressure sensors on the seat and the backrest are within the range of f-0.1f to f+0.1f, and then the adjustment is stopped.

[0033] In addition, the facial information in the information library module of the present invention is stored as a whole unit together with the pressure curve graph obtained after the current facial information is collected and before the next facial information is collected, that is, the driving data information of the fixed driver is stored, so that the cabin adjustment information of a certain passenger can be stored and compared. When the system scans the facial information of a certain passenger, the corresponding data information can be called out, and adaptive adjustments can be directly made on this basis to improve adaptability and be more in line with humanized design.

[0034] Similarly, the data collection module of the present invention receives the acceleration voltage signal from the acceleration sensor and transmits it to the data processing module, which also processes it in the same way to obtain an acceleration curve graph, such as Figure 3 As shown in the figure, when the real-time acceleration a(t) deviates from the two standard lines (a+0.1a and a-0.1a), the data processing module sends a seat belt adjustment signal and a seat adjustment signal to the controller, which controls the seat and backrest to fit closely to the occupant and locks the seat belt at the same time. In this way, the cabin mode can be adjusted instantly so that the seat and backrest are close to the occupant, and the seat belt is locked, thereby enhancing the safety of the occupants when the vehicle experiences a sudden change in acceleration or a collision.

[0035] It should be noted that, in the present invention Figure 2 and Figure 3 The pressure value curve graph and acceleration curve graph shown are only partial images and do not contain all the values. Therefore, the curve graphs may have other shapes, and the diagrams do not represent all the diagrams. The average values ​​f or a are also constantly changing values, but the average value f or a at any time is the average value obtained from the data collected before this time, rather than the average value corresponding to the time. Therefore, there is no average value f or a in the initial section of the curve graph. As information is continuously collected, the average value is gradually obtained.

[0036] See also Figure 4 As shown, the seat control system of the present invention is also provided with an adjustable lumbar support 3, which is located in front of the seat 1. A pressure sensor is also provided on the adjustable lumbar support 3. The adjustable lumbar support 3 can be adjusted forward and backward through the controller. The pressure value of the pressure sensor is sent to the data collection module. When the pressure value of the pressure sensor exceeds the set pressure value p0, the data collection module sends a signal to the controller. The controller adjusts the position of the adjustable lumbar support until the pressure value of the pressure sensor is within the range of p0-0.1p0 to p0+0.1p0. The controller stops adjusting, thereby allowing the adjustable lumbar support 3 to abut and fit against the waist of the passenger, thereby alleviating fatigue during the ride.

[0037] Please continue reading Figure 5 and Figure 6As shown, the adjustable lumbar support 3 of the present invention comprises a base 31 and an abutment 32 located within the base 31. Several hydraulic structures 33 are disposed within the base 31, and the output end of the hydraulic structure 33 is connected to the back of the abutment 32. Furthermore, a positioning shaft 34 is disposed within the base 31, and a pressure spring 35 is hingedly connected thereto. A positioning member 36 is disposed on the back of the abutment 32, and the outer end of the positioning member 36 is hingedly connected to the outer end of the pressure spring 35. Part of the positioning member 36 is located within the positioning shaft 34. A cushion is provided on the front of the abutment 32 to alleviate discomfort in the occupant's waist. Furthermore, the hydraulic structures 33 of the present invention are signal-connected to a controller, which can control the extension and retraction lengths of the several hydraulic structures 33. Pressure differentials are determined by pressure signals transmitted by pressure sensors distributed throughout the adjustable lumbar support 3. If the pressure differential is excessive, the controller adjusts the length of the corresponding hydraulic structure 33, thereby evenly applying force to the adjustable lumbar support 3, especially to the front of the abutment 32. This ensures uniform force on the occupant's waist and improves comfort during long-distance rides.

[0038] Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
