Description

Technical Field

[0001] The present invention relates to the technical field of information push technology, and more specifically, to a premium information push system for a vehicle-mounted central control platform. Background Art

[0002] Currently, the in-vehicle central control has more and more functions, and can display more and more information pages. At present, most of the in-vehicle central control platforms can already search for various nearby information by voice, such as nearby parking information, nearby traffic information, nearby shopping mall information, etc. However, during driving, the driver frequently communicates with the in-vehicle central control platform by voice, which can easily cause the driver's attention to be distracted. In addition, each time the in-vehicle central control platform needs to display the corresponding premium information when the driver issues an instruction, resulting in some drivers being dissatisfied with the efficiency of pushing premium information. How to reduce the driver's communication and interaction with the in-vehicle central control platform during driving, while ensuring the accuracy and efficiency of pushing optimized information, is a problem that needs to be solved urgently. Summary of the invention

[0003] In view of the deficiencies in the prior art, the purpose of the present invention is to provide an optimal information push system for a vehicle-mounted central control platform.

[0004] To achieve the above object, the present invention provides the following technical solutions:

[0005] The premium information push system for the vehicle-mounted central control platform includes the premium information push module, premium information update module, and premium record statistics module;

[0006] The preferred information push module is used to obtain a push reference range when the driver observes the vehicle-mounted central control platform, and push the preferred information to the vehicle-mounted central control platform according to the push reference range;

[0007] The preferred information update module is used to obtain the driver's ideal information value in real time after the vehicle-mounted central control platform pushes the preferred information, and determine whether the preferred information type needs to be updated based on the comparison result between the ideal information value and its threshold value;

[0008] The premium record statistics module is used to generate a premium information reading record after the driver reads the premium information, and to collect statistics on the premium information reading record.

[0009] Furthermore, the push reference range is obtained when the driver observes the vehicle's central control. Specifically, the driver's observation direction is obtained in real time. When the driver's observation direction is the vehicle's central control, a circle is drawn with a preset radius with the current position of the vehicle as the center to obtain the push reference range.

[0010] Furthermore, the preferential information is pushed to the vehicle's central control platform based on the push reference range, specifically: the information preferential value of the vehicle for each type of preferential information within the push reference range is obtained, and each type of preferential information is sorted from large to small according to the information preferential value, and the preferential information of the type with the largest information preferential value is displayed on the vehicle's central control platform first.

[0011] Furthermore, the information preferential value of the vehicle for each type of preferential information within the push reference range is obtained in the following manner: obtain all information preferential logs of the vehicle whose preferential information reading location is within the push reference range before the current system time, obtain the preferential information type of the information preferential log, mark the information preferential logs of the same preferential information type as the same type of information preferential logs, obtain the total number of the same type of information preferential logs, and mark them as DSP, sum up and average all the preferential information reading time of the same type of information preferential logs, obtain the average preferential information reading time, and mark them as TRC, sum up and average all the preferential information reading depths of the same type of information preferential logs, obtain the average preferential information reading depth, and mark them as YDS, sum up the ideal display times of the same type of preferential information before the current system time, obtain the ideal total display times, and mark them as ZCX, and use the formula The vehicle's information preferential value KBZ for this type of preferential information within the push reference range is obtained, where b1 is the coefficient of the number of preferential logs of the same type of information, b2 is the coefficient of the average preferential information reading time, b3 is the coefficient of the average preferential information reading depth, and b4 is the coefficient of the ideal total number of displays.

[0012] Furthermore, after the vehicle-mounted central control platform pushes the premium information, the ideal value of the driver's information is obtained in real time, and based on the comparison result between the ideal value of the information and its threshold, it is determined whether the premium information type needs to be changed, specifically:

[0013] The ideal information value of the driver is obtained in real time, and an ideal information threshold is set. When the ideal information value of the driver is greater than or equal to the ideal information threshold, the current type of preferential information is kept displayed on the vehicle central control platform. When the ideal information value of the driver is less than the ideal information threshold, the display of this type of preferential information on the vehicle central control platform is cancelled, and the preferential information of the next type after this type of preferential information is synchronously displayed on the vehicle central control platform.

[0014] Furthermore, the ideal value of the driver's information is obtained in the following manner: when the type of preferential information is displayed on the vehicle's central control platform, the driver's facial video is captured in real time by a camera, the facial video is converted into a facial video frame, the driver's facial expression in the facial video frame is extracted, and the driver's facial expression is numbered as i according to the time sequence of the facial video frame, i=1, 2, ..., N, N is a positive integer, the driver's facial expression is matched with the information reading expression library to obtain a reading emotion value, which is marked as CZi, and an information reading expression log is generated. The information reading expression log includes a facial expression number and a reading emotion value, and a reading emotion threshold is set. When the reading emotion value is less than the reading emotion threshold, the number of reading losses is increased by one, and all the reading losses after the type of preferential information is displayed on the vehicle's central control platform are summed to obtain the total number of lost readings, which is marked as SPK, and the formula is used. The ideal information value ERT of the driver is obtained, where a1 is the reading emotion value coefficient and a2 is the total number of lost reading times coefficient.

[0015] Furthermore, the information reading expression library is a set of facial expressions of drivers when reading premium information and their corresponding emotional polarities. The emotional polarities include satisfaction and disappointment. Each facial expression in the information reading expression library is associated with a reading emotion value. The reading emotion value of the relevant satisfied facial expression is close to 1, and the reading emotion value of the relevant disappointed facial expression is close to -1.

[0016] Furthermore, after the driver reads the premium information, a premium information reading record is generated, and the premium information reading record is counted, specifically:

[0017] When the driver clicks on the premium information, the system will no longer obtain the driver's ideal value of the information, and increase the ideal display times of this type of premium information by one;

[0018] When the driver exits the Premium Information, a Premium Information reading record is generated, which includes the Premium Information type, Premium Information reading time, Premium Information reading depth, and Premium Information reading location, and simultaneously starts to obtain the driver's ideal information value again.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. Set up a premium information push module to determine the driver's premium information reading needs based on the driver's viewing direction, and analyze various premium information in all aspects when the driver has needs, and push appropriate premium information to the driver, effectively reducing the driver's communication and interaction with the vehicle-mounted central control platform during driving, and improving driving safety;

[0021] 2. Set up a preferential information update module and a preferential record statistics module, and use facial features to analyze in real time whether the type of the driver's preferential information meets the driver's expectations. If it does not meet the driver's expectations, the preferential information type will be updated in time. On the basis of fully ensuring the interactive experience between the driver and the in-vehicle central control platform, the push accuracy and efficiency of the optimized information will be improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Figure 2 A flowchart for changing the preferred information type. DETAILED DESCRIPTION

[0024] Reference Figure 1-Figure 2 , the premium information push system for the vehicle-mounted central control platform includes a premium information push module, a premium information update module, and a premium record statistics module.

[0025] The preferred information push module obtains the driver's viewing direction in real time. When the driver's viewing direction is the vehicle-mounted central control, a circle is drawn with the current position of the vehicle as the center and a preset radius (the preset radius is a system preset value and can be modified according to actual needs) to obtain a push reference range, obtain the information preferred value of the vehicle for each type of preferred information within the push reference range, sort each type of preferred information from large to small according to the value of the information preferred value, and first display the type of preferred information with the largest information preferred value on the vehicle-mounted central control platform.

[0026] A premium information push module is set up to determine the driver's need to read premium information based on the driver's viewing direction, and to analyze various premium information from all angles when the driver has needs, and push appropriate premium information to the driver, effectively reducing the driver's interaction with the on-board central control platform during driving and improving driving safety.

[0027] The preferred information update module: obtains the driver's ideal information value in real time, sets the ideal information threshold, the ideal information threshold is a system-set threshold, and can be modified according to actual needs. When the driver's ideal information value is greater than or equal to the ideal information threshold, the current type of preferred information is displayed on the vehicle's central control platform. When the driver's ideal information value is less than the ideal information threshold, the display of this type of preferred information on the vehicle's central control platform is cancelled, and the preferred information of the next type after this type of preferred information is displayed on the vehicle's central control platform at the same time.

[0028] The preferential record statistics module: when the driver clicks on the preferential information (after the driver clicks on the preferential information, he can see the specific information in the preferential information. For example, when the preferential information is the nearby parking lot information, after the driver clicks on the nearby parking lot information, the location information, remaining parking space information, charging information, etc. of each nearby parking lot will be displayed in detail. The driver can browse or continue to click on the information of the specific parking lot to view it), the ideal value of the driver's information will no longer be obtained synchronously, and the ideal display times of this type of preferential information will be increased by one.

[0029] A preferential information update module and a preferential record statistics module are set up to analyze in real time through facial features whether the type of the driver's preferential information meets the driver's expectations. If it does not meet the driver's expectations, the preferential information type will be updated in time. On the basis of fully ensuring the interactive experience between the driver and the on-board central control platform, the push accuracy and efficiency of the optimized information are improved.

[0030] When the driver exits the premium information, a premium information reading record is generated. The premium information reading record includes the premium information type, premium information reading time (the premium information reading time is the time between the driver clicking on the premium information and exiting the premium information), premium information reading depth (the number of times the driver clicks or browses specific information on the premium information interface), and premium information reading location (the location of the vehicle when the driver clicks on the premium information). At the same time, the ideal value of the driver's information is obtained again.

[0031] The driver's viewing direction is obtained in the following manner: the driver's posture features (such as the direction and angle of the driver's body), head features (such as the direction and angle of the driver's head), and eye features (such as eyeball features) are collected by a camera, and the driver's viewing direction can be obtained through the above features.

[0032] The on-board central control platform is connected to the Internet in real time and can receive various information near the area where the vehicle is located in real time, such as nearby parking information, nearby traffic information, nearby shopping mall information, etc., including but not limited to the above. The above information are all different types of information, and the above information is collectively referred to as premium information.

[0033] The ideal value of the driver's information is obtained in the following way: when the type of preferential information is displayed on the vehicle's central control platform, the driver's facial video is captured in real time by a camera, and the facial video is converted into a facial video frame. The facial video can be converted into a facial video frame by frame extraction, and the driver's facial expression in the facial video frame is extracted, and the driver's facial expression is numbered as i according to the time sequence of the facial video frame, i=1, 2, ..., N, N is a positive integer, the driver's facial expression is matched with the information reading expression library to obtain the reading emotion value, and marked as CZi, and an information reading expression log is generated. The information reading expression log includes the facial expression number and the reading emotion value, and a reading emotion threshold is set. When the reading emotion value is less than the reading emotion threshold, the number of reading losses is increased by one, and all the reading loss times after the type of preferential information is displayed on the vehicle's central control platform are summed up to obtain the total number of lost readings, and marked as SPK, and the formula is used. The ideal information value ERT of the driver is obtained, where a1 is the reading emotion value coefficient, a2 is the total number of lost reading coefficient, the value of a1 is 3.86, and the value of a2 is 1.53.

[0034] The information reading expression library contains the facial expressions of drivers reading premium information and their corresponding emotional polarity sets. The emotional polarity includes satisfaction and disappointment. Each facial expression in the information reading expression library is associated with a reading emotion value. The reading emotion value of the relevant satisfied facial expression is close to 1, and the reading emotion value of the relevant disappointed facial expression is close to -1. Satisfaction indicates that the type of premium information displayed on the vehicle central control platform meets the driver's expectations, and disappointment indicates that the type of premium information displayed on the vehicle central control platform does not meet the driver's expectations.

[0035] The information preferential value of the vehicle for each type of preferential information within the push reference range is obtained in the following manner: obtain all information preferential logs of the vehicle whose preferential information reading location is within the push reference range before the current system time, obtain the preferential information type of the information preferential log, mark the information preferential logs of the same preferential information type as the same type of information preferential logs, obtain the total number of the same type of information preferential logs, and mark them as DSP, sum up and average all the preferential information reading time of the same type of information preferential logs, obtain the average preferential information reading time, and mark it as TRC, sum up and average all the preferential information reading depths of the same type of information preferential logs, obtain the average preferential information reading depth, and mark it as YDS, sum up the ideal display times of the same type of preferential information before the current system time, obtain the ideal total display times, and mark it as ZCX, and use the formula The vehicle's information preferential value KBZ for this type of preferential information within the push reference range is obtained, where b1 is the coefficient of the number of preferential logs of the same type of information, b2 is the coefficient of the average reading time of preferential information, b3 is the coefficient of the average reading depth of preferential information, and b4 is the coefficient of the ideal total number of displays. The value of b1 is 1.32, the value of b2 is 0.98, the value of b3 is 1.17, and the value of b4 is 0.63.
