Description

Technical Field

[0001] This invention relates to the field of automotive cockpit display technology, and in particular to an intelligent display system for a vehicle's central control cockpit. Background Technology

[0002] Intelligent vehicles are comprehensive systems integrating environmental perception, planning and decision-making, and multi-level assisted driving functions. They utilize technologies such as computers, modern sensing, information fusion, communication, artificial intelligence, and automatic control, making them typical high-tech complexes. With the increasing amount of interactive data between users and vehicles, users increasingly expect to obtain interactive information directly from the vehicle cabin. In this regard, technology application number CN201910550237.X provides a vehicle cabin display system. This technical solution includes an instrument display component, a CDU display component, and a host unit. The CDU processing unit and the instrument processing unit are respectively connected to a vehicle interface unit. The instrument processing unit and the CDU processing unit are switchably connected to the first terminal of a first display drive selection switch. The instrument display drive signal is sent to the instrument display component for display through the second terminal of the first display drive selection switch. This vehicle cabin display system adds an instrument processing unit to a host unit with a CDU processing unit. By setting a display drive selection switch, a dual-processor vehicle cabin display system is formed, reducing the probability of display failure.

[0003] Another technology application, numbered 202111462917.X, provides an in-vehicle intelligent cockpit system integrating ETC functionality. This system integrates an ETC module and uses a heterogeneous ARM core hardware isolation scheme to start and control multiple control units within the in-vehicle intelligent cockpit. These control units include at least the instrument cluster, infotainment system, and ETC module. This technical solution addresses the problem in existing technologies where retrofitting ETC devices requires guidance from bank staff and negatively impacts vehicle aesthetics.

[0004] However, traditional center console screens are mostly used for playing music, radio, navigation, and making phone calls. In modern society, for most working people, their commuting times and routes are relatively fixed. Existing vehicle center console screens cannot intelligently play and / or switch the display of family photos based on the driver's daily commuting routes, resulting in a monotonous display that is not conducive to improving the driving experience. Summary of the Invention

[0005] In view of the problems existing in the field of automotive cockpit display technology, the present invention is proposed.

[0006] Therefore, one objective of this invention is to provide an intelligent display system for a vehicle's central control cockpit. This system collects and organizes family photos of the vehicle owner, and simultaneously collects the most frequently driven road segments within a given time period, along with the corresponding times for each road segment. In the future, it can determine whether the vehicle owner has driven a preset vehicle to the corresponding road segment within a given time period. Based on the obtained results, it selects whether to play the organized family photos. Furthermore, when the preset vehicle is driving on the corresponding road segment, the system can adjust the display duration of a single family photo based on changes in the preset vehicle's speed and the remaining length of the road segment, making the vehicle's central control cockpit more intelligent and enhancing the driving experience.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0008] This invention provides an intelligent display system for a vehicle's central control cockpit, comprising:

[0009] The data fusion connection unit is used to enable the vehicle's central control cockpit to obtain data information uploaded by the vehicle owner. The data information includes photos and short videos. The photos are divided into the latest photos, custom photos, and photos with the most views. The data fusion connection unit includes a Bluetooth connection module, a data storage module, and a playback information query module.

[0010] The Bluetooth connection module is used to connect with the vehicle owner's electronic communication terminal via Bluetooth and to receive data information uploaded by the vehicle owner.

[0011] The data storage module is used to store uploaded data information; and the data storage module is divided into... store, store, Storage and Storage, and the various types of storage refer in turn to the storage of the latest photos, custom photos, photos with the most views, and short videos;

[0012] The playback information query module is used to query the car owner about the playback order of various stored data information after the data information has been uploaded, and to sort the playback order in chronological order; the playback order also includes looping playback in the sorted order.

[0013] A playback scene setting module, which responds to the playback information query module by sorting the playback order of various stored data information, is used to set playback scenes for data information with different playback orders. The playback scene setting method includes setting playback according to the different driving sections of the vehicle owner.

[0014] The playback information fusion and analysis unit is used to collect data on the road segments traveled by the driver within a given time period and label each road segment as θ1, θ2, ..., θ n , n represents the nth road segment, wherein the given time period includes the most recent month up to the date of collection; the playback information fusion analysis unit includes a location acquisition module, an entry time statistics module and a playback determination module;

[0015] The location acquisition module is used to acquire the location data collected within the given time period based on each road segment, as well as the location data of the preset vehicle during the driver's driving of the preset vehicle.

[0016] The entry time statistics module is used to calculate the 10 road segments with the most driving times among the statistical road segments within the given time period, mark the road segments as main road segments, and preset the photos and / or short videos to be played in the main road segments.

[0017] The playback determination module is used to determine whether to play the preset photos and / or short videos based on the vehicle location of the preset vehicle. When the preset vehicle is driving in the main road section, the system determines to play the preset photos and / or short videos; otherwise, it does not determine this.

[0018] In a preferred embodiment of the present invention, the following steps are taken: In the main road segment, the maximum number of times a vehicle enters and exits within a given time period is collected. Then, based on the time of these maximum times, the road segments included in the main road segment are divided into a first route, a second route, ..., a tenth route. Specifically, the time nodes corresponding to the divided first to tenth routes are shown in the table below:

[0019]

[0020] When the corresponding time point in the future period arrives, the system determines that the preset vehicle is traveling on the corresponding road segment and plays the preset photos and / or short videos; otherwise, no determination is made.

[0021] In a preferred embodiment of the present invention, feature road segments are collected between adjacent road segments in each of the divided road segments, and at least 5 coordinate points are obtained in the feature road segments. The coordinate points are marked as feature coordinate points. The length of the line formed by the number of obtained feature coordinate points accounts for at least 60% of the length of the feature road segment. When the preset vehicle travels to a certain feature road segment in a future time period, if the collected preset vehicle positioning coordinates are consistent with the feature coordinate points, the system determines that the preset vehicle will travel to the next divided corresponding road segment in the feature road segment; otherwise, no determination is made.

[0022] In a preferred embodiment of the present invention, the coordinate points included in the feature coordinate points are ordered sequentially according to Arabic numerals 1 to 5, wherein the larger the Arabic numeral, the closer the corresponding coordinate point is to the next corresponding road segment connected to the feature road segment. The length of the road segment from the first coordinate point to the second coordinate point is obtained. When the collected positioning coordinates of the preset vehicle are the same as the first coordinate point, the driving speed of the preset vehicle is collected at least 8 to 10 times within 5 seconds. The time required for the preset vehicle to travel to the second coordinate point is calculated based on the driving speed using the following formula:

[0023] Where, δ w This represents the δth driving speed collected during the w-th time within the 5-second period;

[0024] In the formula, t represents the time corresponding to the w-th data collection, and u w The value represents the difference in the change of the driving speed collected for the wth time within the 5-second time interval, and x represents the length of the road segment from the first coordinate point to the second coordinate point.

[0025] If the preset vehicle fails to reach the second coordinate point within the calculated time, the system determines that the preset vehicle is not moving towards the second coordinate point, and the system determines that the preset vehicle does not need to play the preset photo and / or short video when it leaves the characteristic road section; otherwise, no determination is made.

[0026] In a preferred embodiment of the present invention, the average driving speed is calculated from the total number of speed data collections within the 5-second time period. Based on the remaining road segment length between the first and second coordinate points at the time the calculation result is obtained, the time required to travel the remaining road segment length is calculated according to the average driving speed, and the result is obtained using the following formula:

[0027] Among them, R w This represents the time required to complete the remaining road segment for the Rth time, calculated based on the average driving speed, in the wth iteration;

[0028] In the formula, j represents the remaining time based on the time required to complete the remaining road segment of the Rth time, and h e This represents the remaining length of the h-th road segment calculated based on the average driving speed for the w-th time.

[0029] Based on the calculated remaining length of the h-th road segment, if the preset vehicle can travel the remaining length of the road segment according to the average driving speed within the remaining time, the system determines that the preset vehicle is moving towards the second coordinate point, and plays the preset photo and / or short video when the preset vehicle leaves the feature road segment; otherwise, no determination is made.

[0030] In a preferred embodiment of the present invention, the length of each road segment is obtained from the divided road segments. When the preset photo is played in the corresponding road segment, the number of preset photos is calculated, and the speed change of the preset vehicle is collected in the corresponding road segment. The playback progress of the preset photos is set according to the speed change. If the speed of the preset vehicle increases, the system shortens the playback time of a single photo in the preset photos; if the speed of the preset vehicle decreases, the system extends the playback time of a single photo in the preset photos.

[0031] In a preferred embodiment of the present invention, the driving speed and its variation pattern of the preset vehicle on the corresponding road segment are recorded and stored. At the same time, the duration data of the system playing a single photo under the driving speed and its variation pattern are also recorded and stored. When the preset vehicle travels to the same road segment in a future time period, the driving speed and its variation pattern of the preset vehicle are collected. When the driving speed and its variation pattern are the same as the recorded driving speed and its variation pattern, the system does not change the original duration of playing a single photo; otherwise, it adjusts and changes the duration.

[0032] In a preferred embodiment of the present invention, if the playback of the preset photo is paused midway, the distance from the preset vehicle to the end of the corresponding road segment is collected in real time after the playback is paused until the playback of the preset photo is resumed, and the speed change of the preset vehicle is collected based on the remaining distance, and the playback duration of a single photo is updated based on the speed change.

[0033] In a preferred embodiment of the present invention, in the corresponding road segment, two coordinate points 20m apart are set according to the speed change of the preset vehicle, and the time taken to pass through the two coordinate points is given according to the speed change of the preset vehicle. If the time taken for the preset vehicle to pass through the two coordinate points is greater than the given time, the system determines that the preset vehicle is in a traffic jam and further extends the playback time of a single photo in addition to the original extension.

[0034] Beneficial effects:

[0035] This invention collects and organizes family photos of car owners. It also collects data on the most frequently traveled road segments within a given time period and the corresponding times of travel to each segment. This allows the system to determine whether the car owner will drive a pre-defined vehicle to the corresponding road segment within a future timeframe. Based on this result, it selects whether to play the organized family photos. Furthermore, it analyzes and calculates whether the pre-defined vehicle will travel to the corresponding road segment based on characteristic road segments and pre-defined coordinates. The analysis determines whether the organized family photos should be played on the next road segment. When the pre-defined vehicle is traveling to the corresponding road segment, the system adjusts the playback duration of each family photo based on the vehicle's speed and the remaining length of the road segment. This ensures that family photos are displayed one by one within the limited remaining road length, making the vehicle's central control cockpit more intelligent and improving the driving experience.

Detailed Implementation

[0040] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the described embodiments of the present invention are within the scope of protection of the present invention.

[0041] Traditional center console screens are mostly used for playing music, radio, navigation, and making phone calls. However, for most working people in modern society, their commuting times and routes are relatively fixed. Current vehicle center console screens cannot intelligently play and / or switch to display family photos based on the driver's daily commuting routes, resulting in a monotonous display that does not enhance the driving experience.

[0042] Based on this, the present invention proposes an intelligent display system for vehicle central control cockpit. This system collects and organizes family photos of the vehicle owner, and simultaneously collects the most frequently traveled road segments within a given time period, along with the corresponding times for each road segment. In the future, it can determine whether the vehicle owner has driven a preset vehicle to the corresponding road segment within the corresponding time period. Based on the obtained results, it selects whether to play the organized family photos. Furthermore, when the preset vehicle is driving on the corresponding road segment, the system can adjust the display duration of a single family photo based on changes in the preset vehicle's speed and the remaining length of the road segment, making the vehicle central control cockpit more intelligent and improving the driving experience.

[0043] The present solution will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0044] Reference Figures 1 to 2 As one embodiment of the present invention, this embodiment provides a vehicle central control cockpit intelligent display system, including:

[0045] The data fusion connection unit 110 is used to enable the vehicle central control cockpit to obtain data information uploaded by the car owner. The data information includes photos and short videos. Among them, the photos are divided into the latest photos, custom photos and the photos with the most views. The data fusion connection unit 110 includes a Bluetooth connection module 1101, a data storage module 1102 and a playback information query module 1103.

[0046] The Bluetooth connection module 1101 is used to connect with the vehicle owner's electronic communication terminal via Bluetooth and to receive data information uploaded by the vehicle owner;

[0047] It should be noted that electronic communication devices include, but are not limited to, mobile phones and tablets;

[0048] The data storage module 1102 is used to store the uploaded data information; and the data storage module is divided into store, store, Storage and Storage, and the various types of storage represent, in order, the storage of the latest photos, custom photos, the most viewed photos, and short videos;

[0049] The playback information inquiry module 1103 is used to inquire with the car owner about the playback order of various stored data information after the data information has been uploaded, and to sort the playback order according to the order of appearance; the playback order also includes looping playback according to the sorted order.

[0050] The playback scene setting module 120 responds to the playback information query module 1103 to sort the playback order of various types of stored data information, and is used to set the playback scene for data information with different playback orders. The playback scene setting method includes setting the playback according to the different driving sections of the collected vehicle owner.

[0051] The playback information fusion analysis unit 130 is used to collect data on the road segments traveled by the vehicle owner within a given time period and label each road segment as θ1, θ2, ..., θ n , n represents the nth road segment, where the given time period includes the most recent month up to the collection date; the playback information fusion analysis unit 130 includes a positioning acquisition module 1301, an entry time statistics module 1302 and a playback determination module 1303;

[0052] The location acquisition module 1301 is used to acquire the location based on each road segment collected within a given time period, as well as the location of the preset vehicle during the driver's driving of the preset vehicle.

[0053] It should be noted that the transportation management department is the functional department responsible for the management and maintenance of road traffic facilities, including the location information of road sections. Therefore, the location of each road section can be obtained through this department.

[0054] The entry time statistics module 1302 is used to calculate the 10 road segments with the most driving times in each road segment within a given time period, mark the road segments as main road segments, and preset the photos and / or short videos to be played in the main road segments.

[0055] In this embodiment, it should be noted that, within the main road segment, the maximum number of times when vehicles enter and exit within a given time period is collected. Then, based on the time of these maximum times, the main road segment is divided into segments designated as the first route, the second segment, ..., the tenth segment. Specifically, the time nodes corresponding to the first to tenth segments are shown in the table below:

[0056]

[0057] When the corresponding time point in the future period arrives, the system determines that the preset vehicle is traveling on the corresponding road segment and plays the preset photos and / or short videos; otherwise, it does not make a determination.

[0058] Specifically, the length of each road segment is obtained from the divided road segments. When a preset photo is played in the corresponding road segment, the number of preset photos is calculated, and the speed change of the preset vehicle is collected in the corresponding road segment. The playback progress of the preset photos is set according to the speed change. If the speed of the preset vehicle increases, the playback time of a single photo in the preset photo playback is shortened; if the speed of the preset vehicle decreases, the playback time of a single photo in the preset photo playback is extended.

[0059] Based on the above, this embodiment further records and stores the driving speed and its change pattern of the preset vehicle on the corresponding road segment, and also records and stores the duration data of the system playing a single photo under the driving speed and its change pattern. When the preset vehicle travels to the same road segment in a future time period, the driving speed and its change pattern of the preset vehicle are collected. When the driving speed and its change pattern are the same as the recorded driving speed and its change pattern, the system does not change the original duration of playing a single photo; otherwise, it is adjusted and changed.

[0060] Among them, if the playback of the preset photo is paused in the middle, the distance of the preset vehicle to the end of the corresponding road segment is collected in real time after the playback is paused until the playback of the preset photo is resumed. The speed change of the preset vehicle is collected according to the remaining distance, and the playback duration of a single photo is updated based on the speed change.

[0061] In the corresponding road segment, two coordinate points 20m apart are set according to the speed change of the preset vehicle, and the time to pass through the two coordinate points is given according to the speed change of the preset vehicle. If the time to pass through the two coordinate points is longer than the given time, the system determines that the preset vehicle is in a traffic jam and further extends the playback time of a single photo in addition to the original extension.

[0062] Based on the above, in this embodiment, feature road segments are collected between adjacent road segments in each of the divided road segments, and at least 5 coordinate points are obtained in the feature road segments. The coordinate points are marked as feature coordinate points. The length of the line formed by the number of obtained feature coordinate points occupies at least 60% of the length of the feature road segment. When a preset vehicle travels to a certain feature road segment in a future time period, if the collected preset vehicle positioning coordinates are consistent with the feature coordinate points, the system determines that the preset vehicle will travel to the next divided corresponding road segment in the feature road segment. Otherwise, no determination is made.

[0063] Furthermore, in this embodiment, the coordinate points included in the feature coordinate points are ordered sequentially according to Arabic numerals 1 to 5. The larger the Arabic numeral, the closer the corresponding coordinate point is to the next corresponding road segment connected to the feature road segment. Specifically, the length of the road segment from the first coordinate point to the second coordinate point is obtained. When the collected positioning coordinates of the preset vehicle are the same as the first coordinate point, the driving speed of the preset vehicle is collected at least 8 to 10 times within 5 seconds. The time required for the preset vehicle to travel to the second coordinate point is calculated based on the driving speed using the following formula:

[0064] Where, δ w This represents the δ-th speed collected during the w-th time within a 5-second period.

[0065] In the formula, t represents the time corresponding to the w-th data collection, and u w This represents the difference in speed observed during the w-th time within a 5-second interval, where x represents the length of the road segment from the first coordinate point to the second coordinate point.

[0066] If the preset vehicle fails to reach the second coordinate point within the calculated time, the system determines that the preset vehicle is not moving towards the second coordinate point, and the system determines that the preset vehicle does not need to play the preset photo and / or short video when it leaves the feature road segment; otherwise, no determination is made.

[0067] Simultaneously, in this embodiment, the average driving speed is calculated from the total number of speed data collections within a 5-second timeframe. Based on the remaining road segment length between the first and second coordinate points at the time the calculation result is obtained, the time required to travel the remaining road segment length is calculated according to the average driving speed, using the following formula:

[0068] Among them, R w This represents the time required to complete the remaining road segment for the Wth time, calculated based on the average driving speed;

[0069] In the formula, j represents the remaining time based on the time required to complete the remaining road segment of the Rth segment, and h e This represents the remaining length of the h-th road segment calculated based on the average driving speed for the w-th time.

[0070] Based on the calculated remaining length of the h-th road segment, if the preset vehicle can travel the remaining length of the road segment according to the average driving speed within the remaining time, the system determines that the preset vehicle is moving towards the second coordinate point, and plays the preset photo and / or short video when the preset vehicle leaves the feature road segment; otherwise, no determination is made.

[0071] The playback determination module 1303 is used to determine whether to play preset photos and / or short videos based on the vehicle location of the preset vehicle. When the preset vehicle is driving in the main road section, the system determines to play the preset photos and / or short videos; otherwise, it does not determine whether to play them.

[0072] In summary, by collecting and organizing family photos of car owners, and by collecting data on the most frequently traveled road segments within a given time period and the corresponding times of travel to each segment, the system can determine whether the car owner has driven a preset vehicle to the corresponding road segment within a future time period. Based on the results, it can then select whether to play the compiled family photos. Furthermore, it can analyze and calculate whether the preset vehicle will travel to the corresponding road segment based on characteristic road segments and preset coordinate points, and determine whether the compiled family photos need to be played on the next road segment based on the analysis and calculation results. When the preset vehicle is traveling to the corresponding road segment, the system can adjust the playback duration of a single family photo based on the collected data on the vehicle's speed and the remaining length of the road segment. This ensures that family photos are played one by one within the limited remaining road segment length, making the vehicle's central control cockpit more intelligent and improving the driving experience.

[0073] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.

The intelligent display system for a vehicle central control cockpit as described in claim 6, characterized in that, The system records and stores the driving speed and its variation pattern of the preset vehicle on the corresponding road segment. At the same time, it records and stores the duration data of the system playing a single photo under the driving speed and its variation pattern. When the preset vehicle travels to the same road segment in a future time period, the system collects the driving speed and its variation pattern of the preset vehicle. If the driving speed and its variation pattern are the same as the recorded driving speed and its variation pattern, the system does not change the original duration of playing a single photo; otherwise, it adjusts and changes it.

8. The intelligent display system for a vehicle central control cockpit as described in claim 6, characterized in that, If the playback of the preset photo is paused midway, the distance from the preset vehicle to the end of the corresponding road segment is collected in real time after the pause, until the playback of the preset photo is resumed. The speed change of the preset vehicle is collected based on the remaining distance, and the playback duration of a single photo is updated based on the speed change.

9. The intelligent display system for a vehicle central control cockpit as described in claim 6, characterized in that, In the corresponding road segment, two coordinate points 20m apart are set according to the speed change of the preset vehicle, and the time taken to pass through the two coordinate points is given according to the speed change of the preset vehicle. If the time taken for the preset vehicle to pass through the two coordinate points is greater than the given time, the system determines that the preset vehicle is in a traffic jam and further extends the playback time of a single photo in addition to the original extension.
