Description

Technical Field

[0001] This invention belongs to the field of vehicle control and relates to data analysis technology. Specifically, it is an intelligent control system and seat control method for the rear seats of a modified vehicle. Background Technology

[0002] The rear seat control system is usually located on the rear center armrest, which allows for convenient control of media sources, volume adjustment, seat adjustment, and the opening and closing of the panoramic sunroof sunshade, improving the riding experience for rear passengers.

[0003] Regarding the rear-seat control system, some mid-to-low-end models do not have it installed. It is inconvenient for rear passengers to operate the front main control system, and it is also inconvenient for the driver to operate and modify it while concentrating on driving. Even if some mid-to-low-end vehicles have a control system installed between the rear seats, the control functions are incomplete.

[0004] In particular, the comfort of the rear seats is generally worse than that of the front seats. Compared to the driver and front passenger, the rear seats have less stability, so the comfort level varies among different passengers. Consequently, the rear seats are adjusted much more frequently than those in the driver and front passenger seats. Although seat adjustments can be made directly through the control panel, the existing rear seat control system is not intelligent enough for passengers who are not accustomed to or do not know how to use the control panel to adjust the seats. It cannot automatically adjust the seats based on the user's body parameters and big data analysis, thus affecting the passenger's riding experience. Summary of the Invention

[0005] The purpose of this invention is to provide an intelligent control system and seat control method for the rear seats of a modified vehicle, which improves the existing intelligent control system for the rear seats of vehicles, especially the rear seat control system, and further solves the problem that the existing vehicle rear seat control system cannot automatically adjust the seat by combining the user's body parameters with big data analysis.

[0006] The technical problem to be solved by the present invention is: how to provide an intelligent control system and working method for the rear seats of a modified vehicle, especially including an intelligent control system for the rear seats of a vehicle that can automatically adjust the seats by combining the user's body parameters with big data analysis.

[0007] The objective of this invention can be achieved through the following technical solutions:

[0008] An intelligent control system for the rear seats of a modified vehicle includes a control panel, a processor, and a communication data protocol box. The control panel is a touch screen control panel, including an air conditioning control panel and an audio / video navigation control panel. The control panel further includes a backrest adjustment panel, a volume adjustment panel, and a temperature adjustment panel. The backrest adjustment panel includes forward and rear adjustment buttons, the volume adjustment panel includes up and down buttons, and the temperature adjustment panel includes heating and cooling buttons. The communication data protocol box is connected to the original vehicle ECU computer controller.

[0009] The control panel is connected to the central intelligent analysis control module, which in turn connects to the seat ventilation control module, the passenger seat adjustment control module, the communication data protocol box, the gesture control module, the microphone pickup, the Bluetooth module, and the touch screen; the original vehicle ECU computer controller is connected to the original vehicle audio-visual navigation system, the passenger seat, and the original vehicle air conditioning.

[0010] The central intelligent analysis and control module is equipped with a priority determination module. When the original vehicle ECU computer controller is connected to the communication data protocol box to control the original vehicle audio-visual navigation or air conditioning, the front main control system takes the lead in determining whether to agree to the operation. If the front main control system does not respond within 3 seconds, it defaults to agreeing. At this time, the rear air conditioning control panel or audio-visual navigation control panel of the vehicle will be used to control the multimedia or air conditioning. If the front main control system controls the relevant commands, the instructions of the main control system will be executed first.

The matching range of the comfort interval is obtained, and the current backrest and seat tilt value is obtained and marked as the current value. It is determined whether the current value is within the matching range of the comfort interval: if yes, the backrest tilt angle is determined to meet the requirements; if no, the backrest tilt angle is determined to not meet the requirements. The comfort matching module sends a tilt adjustment signal to the processor. After receiving the tilt adjustment signal, the processor sends the tilt adjustment signal to the controller. After receiving the tilt adjustment signal, the controller adjusts the seat tilt angle to the matching value.

[0013] The comfort matching module is used to perform seat comfort matching for the user after receiving the matching object to obtain the matching range and matching value;

[0014] The adjustment analysis module is used to analyze the behavior of passengers adjusting their seatbacks.

[0016] In a preferred embodiment of the present invention, the process of obtaining the matching range and matching value includes: installing a pressure sensor inside the seat to collect the pressure value generated by the passenger on the seat when sitting and marking it as a pressure gauge value; forming a pressure gauge range by the maximum and minimum values ​​of the pressure gauge values ​​of the matching objects; dividing the pressure gauge range into several pressure gauge intervals; grouping the matching objects into the corresponding pressure gauge intervals according to the magnitude of their pressure gauge values; obtaining the backrest tilt angle of the passenger of the matching object within the pressure gauge interval at L2 minutes after boarding and marking it as a tilt value; the backrest tilt angle is the angle formed between the backrest and the seat; forming a matching range by the maximum and minimum values ​​of the tilt values ​​of all matching objects within the pressure gauge interval; and marking the average of the maximum and minimum values ​​of the matching range as the matching value.

[0017] In a preferred embodiment of the present invention, the specific process of the adjustment analysis module analyzing the passenger's backrest adjustment behavior includes: marking the detection object that the passenger adjusts the seat through the backrest adjustment panel after L2 minutes after boarding as the analysis object; marking the time point when the passenger of the analysis object adjusts the backrest as the adjustment point; marking the time period consisting of L3 minutes before and after the adjustment point as the adjustment period; obtaining the maximum and minimum values ​​of the vehicle speed within the adjustment period; marking the difference between the maximum and minimum values ​​of the vehicle speed within the adjustment period as the speed difference value; obtaining the speed difference threshold through the storage module; and comparing the speed difference value with the speed difference threshold: if the speed difference value is less than the speed difference threshold, it is determined that the reason for the backrest adjustment is not related to the driving speed, and a prolonged sitting pattern analysis is performed on the adjustment point; if the speed difference value is greater than or equal to the speed difference threshold, it is determined that the reason for the backrest adjustment is related to the driving speed, and a reminder analysis is performed on the driving speed.

[0018] In a preferred embodiment of the present invention, the process of analyzing the sedentary behavior of adjustment points includes: establishing an adjustment set of adjustment points; calculating the variance of the adjustment set to obtain a dispersion value; obtaining a dispersion threshold through a storage module; comparing the dispersion value with the dispersion threshold; if the dispersion value is less than the dispersion threshold, it is determined that there is a sedentary behavior among the adjustment points; summing the adjustment points and taking the average to obtain the center point; marking the time point L4 minutes before the center point as a warning point; when the vehicle travel time reaches the warning point, the adjustment analysis module sends a sedentary adjustment signal to the processor; after receiving the sedentary adjustment signal, the processor sends the sedentary adjustment signal to the controller; if the dispersion value is greater than or equal to the dispersion threshold, it is determined that there is no sedentary behavior among the adjustment points.

[0019] As a preferred embodiment of the present invention, the process of analyzing driving speed reminders includes: during the vehicle's operation, if the speed difference value at the moment of travel is equal to the speed difference threshold, a speed difference reminder signal is generated and sent to the processor. After receiving the speed difference reminder signal, the processor sends the speed difference reminder signal to the controller. After receiving the speed difference reminder signal, the controller controls the in-vehicle Bluetooth player to play a vehicle speed reminder voice message.

[0020] As a preferred embodiment of the present invention, the seat control operation method of the intelligent rear-seat control system for modified vehicles includes the following steps:

[0021] Step 1: When a passenger sits in the back seat of the car, comfort matching is performed. The pressure gauge value when the passenger is sitting is obtained. By comparing the pressure gauge value with the maximum and minimum values ​​of each pressure gauge interval, the pressure gauge interval that matches the pressure gauge value is obtained and marked as the comfort interval. The matching range of the comfort interval is obtained.

[0022] Step 2: Obtain the current tilt value of the backrest and seat and mark it as the current value. Determine whether the current value is within the matching range of the comfort zone. If yes, the backrest tilt angle is determined to meet the requirements; if no, the backrest tilt angle is determined to not meet the requirements, and the seat tilt angle is adjusted to the matching value through the controller.

[0023] Step 3: Analyze the passenger's backrest adjustment behavior; if the reason for backrest adjustment is unrelated to driving speed and there is a pattern of prolonged sitting between adjustment points, the adjustment analysis module sends a prolonged sitting adjustment signal to the processor when the vehicle travel time reaches the warning point; if the reason for backrest adjustment is related to driving speed, the driving speed is reminded and analyzed.

[0024] The present invention has the following beneficial effects:

[0025] The LCD control panel allows for convenient control of the original car audio and navigation system, passenger and rear seats, and the original car air conditioning.

[0026] 1. Includes media source, volume adjustment, and opening and closing of panoramic sunroof sunshade, carefully taking care of the rear passengers and improving their riding experience;

[0027] 2. The habit analysis module can monitor and analyze the riding habits of rear passengers. By combining the percentage of rear passengers who actively adjust their seats over a period of time, the adjustment habits of rear passengers can be determined. This allows for a more scientific selection of effective reference objects from all the monitored objects as matching objects. Finally, the comfort matching is achieved by adjusting the backrest tilt angle of the matching object.

[0028] 3. The comfort matching module can match the seat comfort for rear passengers of different "weight classes". It divides the pressure value of the passenger on the seat to obtain the pressure gauge range of the passenger. Then, it determines whether the seat needs to be automatically adjusted by matching the matching range corresponding to the pressure gauge range and the current backrest tilt angle. This allows the seat to be adjusted immediately after the rear passengers get in the car, improving the riding comfort of the rear passengers.

[0029] 4. The adjustment and analysis module can analyze passengers' seat adjustment behavior, analyze and determine the factors affecting seat adjustment during the ride, and then supervise driving regulations based on the influencing factors. At the same time, it can analyze the pattern of passengers adjusting their seats after sitting for a long time, and automatically adjust the seats at the corresponding time when the vehicle travel time is too long, further improving the passenger's riding comfort.

[0030] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0032] Figure 2 This is a schematic block diagram illustrating the system principle of Embodiment 1 of the present invention;

[0033] Figure 3 This is a schematic diagram of the seat control method for seat adjustment according to Embodiment 2 of the present invention. Detailed Implementation

[0034] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] like Figure 1 The diagram shows the principle of the intelligent control system for the rear seats of a vehicle according to the present invention. This solution provides an intelligent control system for the rear seats of a modified vehicle, comprising a control panel, a processor, and a communication data protocol box. The control panel is a touchscreen control panel, including an air conditioning control panel and an audio / video navigation control panel. The control panel also includes a backrest adjustment panel, a volume adjustment panel, and a temperature adjustment panel. The backrest adjustment panel includes forward and rear adjustment buttons, the volume adjustment panel includes up and down buttons, and the temperature adjustment panel includes heating and cooling buttons. The communication data protocol box is connected to the original vehicle ECU computer controller.

[0036] The control panel is connected to the central intelligent analysis control module, which in turn connects to the seat ventilation control module, the passenger seat adjustment control module, the communication data protocol box, the gesture control module, the microphone pickup, the Bluetooth module, and the touch screen; the original vehicle ECU computer controller is connected to the original vehicle audio-visual navigation system, the passenger seat, and the original vehicle air conditioning.

[0037] The central intelligent analysis and control module is equipped with a priority determination module. When the original vehicle ECU computer controller is connected to the communication data protocol box to control the original vehicle audio-visual navigation or air conditioning, the front main control system takes the lead in determining whether to agree to the operation. If the front main control system does not respond within 3 seconds, it defaults to agreeing. At this time, the rear air conditioning control panel or audio-visual navigation control panel of the vehicle will be used to control the multimedia or air conditioning. If the front main control system controls the relevant commands, the instructions of the main control system will be executed first.

[0038] The intelligent control system for the rear seats of the vehicle is located in the middle of the rear seats or in a position slightly behind the front seats between the driver and front passenger seats, making it convenient for rear passengers to operate and play videos. When located in the middle of the rear seats, it can be folded up and lifted to fit snugly against the rear seat back, forming a backrest at the bottom; when folded flat, it forms a touchscreen control panel; when located slightly behind the front seats between the driver and front passenger seats, it forms an angle between 30 and 60 degrees with the horizontal plane, making it convenient for rear passengers to operate and watch videos.

[0039] When the rear air conditioning control panel is selected to control the rear air conditioning, the front air conditioning remains unchanged. When viewing the front navigation image, the navigation can be displayed on both the front and rear screens simultaneously. The navigation can also be modified. It is safer for rear passengers to modify the navigation as it is inconvenient for the front driver to do so. After modification, the modified navigation can be displayed on both the front and rear screens simultaneously. In this case, if the front control system does not deny or cancel the rear control command, it is considered as agreed by default. The front control system can reclaim control at any time.

[0040] The specific details regarding the control system for the front passenger seat or rear seats are as follows:

[0041] Example 1

[0042] like Figure 2 As shown, an intelligent control system for the rear seats of a modified vehicle includes a processor, which is communicatively connected to a habit analysis module, a comfort matching module, an adjustment analysis module, a control panel, a controller, and a storage module.

[0043] The habit analysis module monitors and analyzes the seating habits of rear-seat passengers. The passenger journey within L1 days is marked as the detection object i, i = 1, 2, ..., n, where n is a positive integer. Passengers who adjust their seats using the backrest adjustment panel within L2 minutes of boarding are marked as "adjusting objects," and the remaining passengers are marked as "non-adjusting objects." Here, adjusting objects are passengers who actively adjust their seats, while non-adjusting objects include passengers who do not actively adjust their seats and passengers whose backrest angle already matches their seating habits. The number of adjusting objects is obtained and marked as t, and the ratio of t to n is marked as the adjustment rate. An adjustment threshold is obtained through the storage module, and the adjustment rate is compared with the adjustment threshold. If the adjustment rate is less than the adjustment threshold, the user habit is determined to be non-adjusting, and the adjusting object is marked as a matching object. When most rear-seat passengers do not adjust their seats, since this group of passengers includes those who do not adjust their seats... For passengers who are conscious of adjusting their seats and those whose backrest angles already match their seating habits, it's unknown whether the backrest angles actually suit their habits. However, it's certain that a small number of passengers who are conscious of adjusting their seats will have backrest angles that match their seating habits after adjustment. Therefore, these adjusted passengers are marked as matching targets for analysis. If the adjustment rate is greater than or equal to the adjustment threshold, the user habit is considered to be adjusting, and all detected passengers are marked as matching targets. These matching targets are then sent to the comfort matching module. The seating habits of rear passengers are monitored and analyzed. The percentage of rear passengers actively adjusting their seats over a period of time is used to determine their adjustment habits, thus allowing for a more scientific selection of effective reference targets from all detected passengers as matching targets. Finally, comfort matching is achieved based on the final backrest angle adjusted by these matching targets.

[0044] The comfort matching module performs seat comfort matching for users after receiving a matching object: Pressure sensors are installed inside the seat to collect and mark the pressure values ​​exerted by passengers when sitting on the seat as pressure gauge values. The maximum and minimum values ​​of the pressure gauge values ​​for the matching objects constitute a pressure gauge range. This range is further divided into several pressure gauge intervals. Matching objects are grouped into corresponding pressure gauge intervals based on their pressure gauge values. The backrest tilt angle of the passengers within each pressure gauge interval is obtained and marked as the tilt value at L2 minutes after boarding. This tilt value conforms to the corresponding passenger's sitting habits. The backrest tilt angle is the angle formed between the backrest and the seat. The maximum and minimum tilt values ​​of all matching objects within a pressure gauge interval constitute a matching range, and the average of the maximum and minimum values ​​within this range is marked as the matching value. When a passenger sits in the back seat, comfort matching is performed: the pressure gauge value of the passenger when sitting is obtained, and the value is compared with the maximum and minimum values ​​of each pressure gauge interval to obtain the corresponding pressure gauge value. The system matches the pressure gauge intervals and marks them as comfort zones. It then obtains the matching range of these comfort zones, which represents the appropriate range of backrest tilt angles previously chosen by passengers of similar weight. The system obtains the current backrest and seat tilt values ​​and marks them as the current value. It then determines whether the current value falls within the matching range of the comfort zone: if yes, the backrest tilt angle meets the requirements; otherwise, it does not. The comfort matching module sends a tilt adjustment signal to the processor. Upon receiving the tilt adjustment signal, the processor sends it to the controller. The controller then adjusts the seat tilt angle to the matching value. Seat comfort matching is performed for rear passengers of different "weight classes." Based on the pressure values ​​exerted by the passengers on the seat, the system divides the passengers into pressure gauge intervals. By using the matching range corresponding to the pressure gauge interval and the current backrest tilt angle, it determines whether the seat needs automatic adjustment, allowing for immediate seat adjustment for rear passengers upon boarding and improving their comfort.

[0045] The adjustment analysis module is used to analyze passenger backrest adjustment behavior: Passengers who adjust their seats via the backrest adjustment panel after L2 minutes of boarding are marked as analysis objects. The time point when the passenger adjusts their backrest is marked as the adjustment point. The time period L3 minutes before and after the adjustment point is marked as the adjustment period. The maximum and minimum vehicle speeds within the adjustment period are obtained, and the difference between the maximum and minimum vehicle speeds within the adjustment period is marked as the speed difference value. The speed difference threshold is obtained through the storage module, and the speed difference value is compared with the speed difference threshold. If the speed difference value is less than the speed difference threshold, it is determined that the reason for the backrest adjustment is unrelated to the driving speed, and the prolonged sitting pattern is analyzed at the adjustment point; if the speed difference value is greater than or equal to the speed difference threshold, it is determined that the reason for the backrest adjustment is related to the driving speed, and the driving speed is reminded and analyzed; the passenger's seat adjustment behavior is analyzed, the factors affecting seat adjustment during the ride are analyzed and determined, and then the driving regulations are supervised based on the influencing factors. At the same time, the pattern of passengers adjusting their seats after prolonged sitting is analyzed, and when the vehicle travel time is too long, the seat is automatically adjusted at the corresponding time point to further improve the passenger's riding comfort.

[0046] The process of analyzing sedentary patterns at adjustment points includes: establishing an adjustment set of adjustment points; calculating the variance of the adjustment set to obtain the dispersion value; obtaining the dispersion threshold through the storage module; comparing the dispersion value with the dispersion threshold; if the dispersion value is less than the dispersion threshold, it is determined that there is a sedentary pattern among the adjustment points; summing and averaging the adjustment points to obtain the center point; marking the time point L4 minutes before the center point as the warning point; when the vehicle travel time reaches the warning point, the adjustment analysis module sends a sedentary adjustment signal to the processor; after receiving the sedentary adjustment signal, the processor sends the sedentary adjustment signal to the controller; if the dispersion value is greater than or equal to the dispersion threshold, it is determined that there is no sedentary pattern among the adjustment points.

[0047] The process of analyzing driving speed reminders includes: during vehicle operation, if the speed difference value at the moment of travel is equal to the speed difference threshold, a speed difference reminder signal is generated and sent to the processor. After receiving the speed difference reminder signal, the processor sends it to the controller. After receiving the speed difference reminder signal, the controller controls the in-vehicle Bluetooth player to play a vehicle speed reminder voice message to monitor driving behavior.

[0048] The control panel includes a backrest adjustment panel, a volume adjustment panel, and a temperature adjustment panel. The backrest adjustment panel includes forward and rear adjustment buttons, the volume adjustment panel includes up and down buttons, and the temperature adjustment panel includes heat up and cool down buttons. The control panel allows for convenient control of media sources, volume adjustment, and the opening and closing of the panoramic sunroof sunshade, carefully catering to the needs of rear passengers and enhancing their riding experience.

[0049] Example 2

[0050] like Figure 3 As shown, a method for controlling the seats in a smart control system for the rear seats of a modified vehicle includes the following steps:

[0051] Step 1: When a passenger sits in the back seat of the car, comfort matching is performed. The pressure gauge value when the passenger is sitting is obtained. By comparing the pressure gauge value with the maximum and minimum values ​​of each pressure gauge interval, the pressure gauge interval that matches the pressure gauge value is obtained and marked as the comfort interval. The matching range of the comfort interval is obtained.

[0052] Step 2: Obtain the current tilt value of the backrest and seat and mark it as the current value. Determine whether the current value is within the matching range of the comfort zone. If yes, the backrest tilt angle is determined to meet the requirements; if no, the backrest tilt angle is determined to not meet the requirements, and the seat tilt angle is adjusted to the matching value through the controller.

[0053] Step 3: Analyze the passenger's backrest adjustment behavior; if the reason for backrest adjustment is unrelated to driving speed and there is a pattern of prolonged sitting between adjustment points, the adjustment analysis module sends a prolonged sitting adjustment signal to the processor when the vehicle travel time reaches the warning point; if the reason for backrest adjustment is related to driving speed, the driving speed is reminded and analyzed.

[0054] An intelligent control system for the rear seats of a vehicle performs comfort matching when a passenger sits in the rear seat. It acquires the pressure gauge value at the time of passenger occupancy, compares this value with the maximum and minimum values ​​of various pressure gauge intervals to identify the pressure gauge interval matching the current value and marks it as the comfort interval, thus determining the matching range of the comfort interval. It also acquires the current backrest and seat tilt values ​​and marks them as the current value. The system determines whether the current value is within the matching range of the comfort interval. If it is, the backrest tilt angle meets the requirements; otherwise, the backrest tilt angle does not meet the requirements, and the controller adjusts the seat tilt angle to the matching value.

[0055] The present invention provides an intelligent control system and seat control method for the rear seats of vehicles, which improves existing rear multimedia control systems or modifies vehicles without a rear control system. By connecting to the original vehicle computer controller through the original vehicle ECU interface, the system can be modified for low- to mid-range models, improving the riding experience for rear passengers without affecting the driver's concentration on driving. At the same time, rear passengers can directly adjust their seats, which improves the riding experience while avoiding interference with the driver and increasing the safety factor during driving.

The intelligent control system for the rear seats of a modified vehicle according to claim 1, characterized in that, The process of analyzing sedentary patterns at adjustment points includes: establishing an adjustment set of adjustment points; calculating the variance of the adjustment set to obtain the dispersion value; obtaining the dispersion threshold through the storage module; comparing the dispersion value with the dispersion threshold; if the dispersion value is less than the dispersion threshold, it is determined that there is a sedentary pattern among the adjustment points; summing and averaging the adjustment points to obtain the center point; marking the time point L4 minutes before the center point as the warning point; when the vehicle travel time reaches the warning point, the adjustment analysis module sends a sedentary adjustment signal to the processor; after receiving the sedentary adjustment signal, the processor sends the sedentary adjustment signal to the controller; if the dispersion value is greater than or equal to the dispersion threshold, it is determined that there is no sedentary pattern among the adjustment points.

3. The intelligent control system for the rear seats of a modified vehicle according to claim 2, characterized in that, The process of analyzing driving speed reminders includes: during vehicle operation, if the speed difference value at the moment of travel is equal to the speed difference threshold, a speed difference reminder signal is generated and sent to the processor. After receiving the speed difference reminder signal, the processor sends the speed difference reminder signal to the controller. After receiving the speed difference reminder signal, the controller controls the in-vehicle Bluetooth player to play a vehicle speed reminder voice message.

4. A smart control system for the rear seats of a modified vehicle according to any one of claims 1-3, characterized in that, The intelligent control system connects to the original vehicle ECU computer controller via a communication data protocol box; the seat control operation method of this intelligent control system used for vehicle rear seat modification is as follows. Step 1: When a passenger sits in the back seat of the car, comfort matching is performed. The pressure gauge value when the passenger is sitting is obtained. By comparing the pressure gauge value with the maximum and minimum values ​​of each pressure gauge interval, the pressure gauge interval that matches the pressure gauge value is obtained and marked as the comfort interval. The matching range of the comfort interval is obtained. Step 2: Obtain the current tilt value of the backrest and seat and mark it as the current value. Determine whether the current value is within the matching range of the comfort zone. If yes, the backrest tilt angle is determined to meet the requirements; if no, the backrest tilt angle is determined to not meet the requirements, and the seat tilt angle is adjusted to the matching value through the controller. Step 3: Analyze the passenger's backrest adjustment behavior; if the reason for backrest adjustment is unrelated to driving speed and there is a pattern of prolonged sitting between adjustment points, the adjustment analysis module sends a prolonged sitting adjustment signal to the processor when the vehicle travel time reaches the warning point; if the reason for backrest adjustment is related to driving speed, the driving speed is reminded and analyzed.
