Detailed implementation manners

[0043] The following details the implementation manners of the present invention. Examples of the implementation manners are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The implementation manners described below by referring to the drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation of the present invention.

[0044] In the related art, it is possible to generate a lane-level navigation display screen by combining the lane-level data of a map provider and the environmental information collected by vehicle sensors. However, the display content of the lane-level navigation display screen is not rich enough to meet the needs of users' safe driving.

[0045] Please refer to Figures 1 to 3 , the display method of the present invention can be used for the vehicle-mounted system 11, and the vehicle-mounted system 11 is arranged on the vehicle 10. The display method includes:

[0046] 012: When obtaining the lane-level data of the map and the environmental data when the vehicle 10 is driving on the current road, generate an environmental simulation screen according to the lane-level data and the environmental data. The environmental simulation screen displays several lanes corresponding to the current road;

[0047] 014: Generate bubble information 21 according to the navigation assistance information of the target location point;

[0048] 016: Integrate the bubble information 21 with the environmental simulation screen to generate a navigation simulation screen.

[0049] The vehicle 10 includes an in-vehicle system 11 and a body 13, and the in-vehicle system 11 is disposed on the body 13. The in-vehicle system 11 may include at least one of display components such as an instrument panel screen, a central control screen, a head-up display system (HUD) on the front windshield, and an extended reality system (XR). In some embodiments, the vehicle 10 can display the navigation simulation screen of the above embodiments through the in-vehicle system 11. In other embodiments, the vehicle 10 can also display the navigation simulation screen through a terminal device with a display function that can communicate with the vehicle 10. In one embodiment, the terminal device can be a mobile phone.

[0050] In the above display method, the user can know the navigation assistance information of the target position point through the bubble information 21, thereby facilitating the user to control the vehicle 10 and improving driving safety.

[0051] Specifically, the map can be a high-precision map provided by a supplier. The map may include lane-level data, place names, buildings, natural landscapes, etc. The lane-level data may include lane data, tunnel data, bridge data, guardrail data, electronic eye data, etc. The map can be stored in a cloud server or in the local memory of the vehicle 10, which is not limited herein. In some embodiments, the map is stored in a cloud server, and the vehicle 10 can connect to the cloud server through a wireless communication method (such as WIFI, a mobile communication network, etc.), and then the vehicle 10 obtains the lane-level data of the map from the cloud server. In certain embodiments, the map is stored in the local memory of the vehicle 10, and then the vehicle 10 obtains the lane-level data of the map from the local memory of the vehicle 10. In other embodiments, the lane-level data of the map is static.

[0052] For the environmental data, it may include surrounding pedestrians, the position information of surrounding pedestrians, surrounding vehicles, the position information of surrounding vehicles, etc. Specifically, in such an embodiment, the vehicle 10 may include an environmental perception sensor (not shown in the figure). The environmental perception sensor can real-time obtain the data information of the dynamic changes around the vehicle 10 and generate corresponding electrical signals. By processing the electrical signals generated by the environmental perception sensor, the environmental data of the vehicle 10 can be obtained, and then the information related to the environment around the vehicle 10 can be directly obtained. The environmental perception sensor may include a high-definition camera, a millimeter-wave radar, an ultrasonic radar, a lidar, an attitude sensor, a positioning sensor, etc. The specific type of the environmental perception sensor is not limited herein. It can be understood that the environmental data is dynamic.

[0053] In some embodiments, the environmental perception sensors may be disposed on the roof of the vehicle 10, or may be disposed around the vehicle 10 on the front, rear, and doors of the vehicle.

[0054] In a case where lane-level data and environmental data are obtained, in such an embodiment, the lane-level data and the environmental data may be fused to obtain an environmental simulation image. Specifically, the environmental simulation image may display the real-scene information of several lanes of the road where the vehicle 10 is located, such as the vehicles in front of and behind the vehicle 10 in the lane where the vehicle 10 is located, other vehicles in the adjacent lanes, lane markings, road sign information, and road types, so that the user can determine whether there is a sufficient distance from the vehicles in front of and behind according to the environmental simulation image, whether the conditions for changing lanes to the adjacent lanes are met, whether the vehicle 10 deviates from the current lane, the restriction conditions of the current road section on the vehicle 10 (such as vehicle speed, whether high beam lights can be turned on), and whether steering is required, etc., so as to intuitively grasp the dynamic changes around the vehicle 10 and facilitate the user to make corresponding judgments and operations in a timely manner.

[0055] On the basis of the above, in a case where the environmental simulation image has been generated, the environmental simulation image may be subjected to corresponding fusion processing according to the navigation assistance information of the target position point. Specifically, the target position point may refer to a key position point during the driving process of the vehicle 10. By generating the bubble information 21 from the navigation assistance information of the key position point, more accurate driving prompts can be given to the user. The bubble information 21 may refer to the information presented in the form of a bubble. Among them, the bubble form may be a circular bubble, an oval bubble, a rectangular bubble, etc., which are not specifically limited herein. The content in the bubble information 21 may be determined according to the navigation assistance information. The bubble information 21 may have a pointing protrusion, and the pointing protrusion may point to the target position point, so that the navigation assistance information of the target position point can be displayed through the bubble information 21 as a prompt message. The navigation assistance information of the target position point is abstract information, and the information that cannot be seen in the real environment can be displayed through the bubble information 21. The bubble information 21 can give the user a more intuitive driving prompt at the target position point, thereby improving driving safety. The bubble information 21 is fused in the environmental simulation image for corresponding optimization processing, so that the user can determine the navigation assistance information of the target position point according to the optimized navigation simulation image.

[0056] It can be understood that in practical applications, since the user needs to concentrate on confirming and judging the surrounding environment, if it is necessary to confirm the navigation assistance information of the target position point at this time, the user needs to distract his attention to observe and think. In the embodiments of the present invention, while the user can judge the environment where the vehicle 10 is currently located through the navigation simulation screen, the navigation assistance information of the target position point can be conveniently and quickly confirmed according to the bubble information 21 in the navigation simulation screen. The content displayed on the navigation simulation screen is richer and can have more comprehensive functions, providing users with one-stop driving information, not easily causing distraction of the user during driving, and being beneficial to improving safety.

[0057] The target position point includes an electronic eye, and the navigation assistance information includes speed limit photography, illegal photography or running a red light photography. Different navigation assistance information corresponds to different bubble information 21.

[0058] In this way, the navigation assistance information of the electronic eye can be prompted through the bubble information 21, so that the user can drive safely and regularly according to the bubble information 21.

[0059] Please continue to refer to Figure 3 , specifically, when the electronic eye is a speed limit photography electronic eye, the corresponding navigation assistance information is speed limit photography. The speed limit photography includes a limited speed. For example, the speed limit is 80 km / h. The bubble information 21 can be the speed limit photography bubble information 2112. The speed limit photography bubble information 2112 can be a circular bubble information, and the content in the circular area can be the speed limited by the speed limit photography, such as "80". When the electronic eye is an illegal photography electronic eye, the corresponding navigation assistance information is illegal photography. The bubble information 21 can be the illegal photography bubble information 2114. The illegal photography bubble information 2114 can be a circular bubble information, and the content in the circular area can be a camera graphic. When the electronic eye is a running a red light photography electronic eye, the corresponding navigation assistance information is running a red light photography. The bubble information 21 can be the running a red light photography bubble information 2116. The running a red light photography bubble information 2116 can be a circular bubble information, and the content in the circular area can be a traffic light graphic.

[0060] Please refer to Figure 4 , the display method further includes:

[0061] 018: When the navigation assistance information is speed limit photography and the vehicle speed of the vehicle 10 exceeds the speed limited by the speed limit photography, mark the bubble information 21 for warning.

[0062] In this way, warning can be given by marking the bubble information 21, so that the user can know that the vehicle 10 has exceeded the speed limit.

[0063] Specifically, speed limit photography includes a limited speed. When the vehicle speed of vehicle 10 exceeds the speed limit set by the speed limit photography, a warning prompt should be given to the user. Among them, the warning prompt can be achieved by marking the bubble information 21. Specifically, the marked bubble information can be to change the color of the bubble information 21. For example, please refer to Figure 5 the left figure of Figure 5 . When the vehicle speed of vehicle 10 does not exceed the speed limit set by the speed limit photography, the bubble information 21 is the normal bubble information 2122, and the color of the edge of the normal bubble information 2122 is white; please refer to

[0064] the right figure of

[0065] . When the vehicle speed of vehicle 10 exceeds the speed limit set by the speed limit photography, the bubble information 21 is the warning bubble information 2124, and the color of the edge of the warning bubble information 2124 is red. Of course, the bubble information 21 can also be marked in other ways. For example, the bubble information 21 blinks as a mark, the style of the bubble information 21 changes as a mark, etc., which are not specifically limited here. Figure 6 The display method further includes:

[0066] 022: Determine the style of the bubble information 21 according to the number of violation records of the traffic camera.

[0067] In this way, the user can determine the number of violation records of the traffic camera through the style of the bubble information 21, and thus better control the vehicle 10 according to the number of violation records.

[0068] Specifically, the style of the bubble information 21 includes the size of the bubble information 21, the amount of information content included in the bubble information 21, the shape of the bubble information 21, etc. Please refer to Figure 7, taking the speed limit camera as an example, when the number of violation records of the speed limit camera is more than the preset number, the bubble information 21 can be the first bubble information 2132. The first bubble information 2132 can be an oval bubble information. The first bubble information 2132 includes a circular area, and the content in the circular area is the speed limited by the speed limit camera, such as "60". In addition, it can also include the distance between the target position point and the vehicle 10, such as "200 meters", and can also display the words "more violations". When the number of violation records is 0 (no violation records), the bubble information 21 can be the second bubble information 2134. The second bubble information 2134 can be a circular bubble information. The content in the circular area is the speed limited by the speed limit camera, such as "80". When the number of violation records is greater than 0 and less than the preset number, the bubble information 21 can be the third bubble information 2136. The third bubble information 2136 can be a circular bubble information. The content in the circular area is the speed limited by the speed limit camera, such as "80". Among them, the size of the second bubble information 2134 is smaller than the size of the third bubble information 2136.

[0069] The target position point includes the turn-by-turn point, and the navigation assistance information includes the diverging information, merging information or turning information. Different navigation assistance information corresponds to different bubble information 21.

[0070] In this way, the navigation assistance information of the turn-by-turn point can be prompted through the bubble information 21, so that the user can drive safely and regularly according to the bubble information 21.

[0071] Specifically, the turn-by-turn point includes key turn-by-turn points such as diverging, merging, and turning. When the navigation assistance information is the diverging information, the bubble information 21 can be the diverging bubble information. When the navigation assistance information is the merging information, the bubble information 21 can be the merging bubble information. When the navigation assistance information is the turning information, the bubble information 21 can be the turning bubble information 2142. Please refer to Figure 8 , this invention takes the navigation assistance information as the turning information and the bubble information 21 as the turning bubble information 2142 as an example for illustration. The turning bubble information 2142 can be a circular bubble information, and the content in the circular area can be a turning graphic.

[0072] Please refer to Figure 9 , the display method further includes:

[0073] 024: Obtain the distance between the target position point and the vehicle 10;

[0074] Step 014 (generating the bubble information 21 according to the navigation assistance information of the target position point) includes:

[0075] 0142: Generate bubble information 21 based on navigation assistance information and distance.

[0076] In this way, distance information can be incorporated into the bubble information 21, so as to display the distance between the target position point and the vehicle 10, facilitating the user to accurately determine the position of the target position point.

[0077] Specifically, as Figure 10 shown, the target position point includes a speed camera, the navigation assistance information includes speed limit photography, and the bubble information 21 is, for example, speed limit photography bubble information 2112. The speed limit photography bubble information 2112 can be an oval bubble information. The speed limit photography bubble information 2112 includes a circular area, and the content in the circular area is the speed limited by the speed limit photography, such as "80", and the distance can be displayed in other areas, such as "20 meters", "78 meters", "300 meters", etc. As Figure 11 shown, the bubble information 21 is, for example, turning bubble information 2142. The turning bubble information 2142 can be an oval bubble information. The turning graph can be displayed in the left area, and the distance can be displayed in the right area, such as "87 meters".

[0078] In the environmental simulation screen, the size of the object is negatively correlated with the object distance (the distance between the object and the vehicle 10). For example, the larger the object distance, the farther the object is from the vehicle 10, and the smaller the object is. The size of the bubble information 21 can be independent of the distance (the distance between the target position point and the vehicle 10), that is, at different distances, the size of the same type of bubble information 21 is consistent. In this way, it can be ensured that the size of the bubble information 21 is appropriate for the user to view.

[0079] Please refer to Figure 12 , and the display method further includes:

[0080] 026: Determine a progress bar according to the ratio of the distance to the preset distance;

[0081] Step 0142 (generating bubble information 21 based on navigation assistance information and distance) includes:

[0082] 01422: Generate bubble information 21 based on navigation assistance information, distance, and a progress bar.

[0083] In this way, a progress bar can be incorporated into the bubble information 21, and the user can more intuitively see the distance between the target position point and the vehicle 10 through the progress bar.

[0084] Specifically, the progress bar can be determined according to the ratio of the distance to the preset distance. The preset distance can be set in advance. For example, 300m is set in advance as the preset distance. The preset distance can also be determined according to the driving scenario. For example, when the vehicle speed of vehicle 10 is greater than the preset vehicle speed, since the vehicle speed is relatively fast, in order to ensure driving safety, the navigation assistance information of the target position point needs to be prompted earlier. The preset distance can be the first preset distance. When the vehicle speed of vehicle 10 is less than the preset vehicle speed, since the vehicle speed is relatively slow, the navigation assistance information of the target position point can be prompted slightly slower. The preset distance can be the second preset distance, and the first preset distance is greater than the second preset distance. Please refer to Figure 10 , when the distance between the target position point and vehicle 10 is less than the preset distance, the distance between the target position point and vehicle 10 has a positive correlation with the progress of the progress bar. That is to say, the greater the distance between the target position point and vehicle 10, the closer the progress of the progress bar is to 100%. As vehicle 10 travels, the smaller the distance between the target position point and vehicle 10, the closer the progress of the progress bar is to 0. In addition, when the distance between the target position point and vehicle 10 is greater than the preset distance, the distance and the progress bar may not be displayed. After vehicle 10 passes the target position point, the bubble information 21 disappears.

[0085] Please refer to Figure 13 , the display method further includes:

[0086] 028: When the target position point is a navigation maneuver point, obtain lane information;

[0087] Step 0142 (generating the bubble information 21 according to the navigation assistance information and the distance) includes:

[0088] 01424: Generate the bubble information 21 according to the navigation assistance information, the distance, and the lane information.

[0089] In this way, the lane information can be incorporated into the bubble information 21. The lane information can provide a more intuitive lane-changing prompt, and the user can plan the driving route of the navigation maneuver point according to the lane information.

[0090] Specifically, the lane information may include the types of each lane. The types of lanes include one or more of a straight lane, a left-turn lane, a right-turn lane, a U-turn lane, etc. According to the lane information, the user can relatively easily determine how to control vehicle 10 when passing through the navigation maneuver point. Please refer to Figure 14, the navigation assistance information includes steering information. The bubble information 21 is, for example, steering bubble information 2142. The steering bubble information 2142 can be oval bubble information. The left area can display the graphics of each lane as lane information. Among them, the steering graphics can be highlighted by bolding, different colors, etc. The right area can display the distance, such as "87 meters".

[0091] The target location point includes a congested section. The navigation assistance information includes the length of the congested section and the congestion time.

[0092] In this way, the navigation assistance information of the congested section can be prompted through the bubble information, so that the user can drive safely and regularly according to the bubble information 21.

[0093] Specifically, please refer to Figure 15 , the navigation assistance information includes the length of the congested section and the congestion time. The length of the congested section can refer to the total length of the congested section. The congestion time can refer to the estimated time spent passing through the congested section. The bubble information 21 can be congestion bubble information 2152. The congestion bubble information 2152 can be square bubble information. The left area can display the relevant graphics of the congested section. The right area can display the length of the congested section and the congestion time, such as "800 meters", "15 minutes".

[0094] The target location point includes a section with bad weather. The navigation assistance information includes the bad weather condition.

[0095] In this way, the navigation assistance information of the section with bad weather can be prompted through the bubble information, so that the user can drive safely and regularly according to the bubble information 21.

[0096] Specifically, please refer to Figure 16 , the navigation assistance information includes the bad weather condition. The bad weather condition includes weather conditions such as heavy rain, snow, hail, and fog that affect the normal driving of the vehicle 10. The bubble information 21 can be weather bubble information 2162. The weather bubble information 2162 can be square bubble information. The left area can display the relevant graphics of the bad weather condition. The right area can display the text information and prompt information of the bad weather condition, such as "Heavy rain ahead", "Please drive carefully".

[0097] Please refer to Figure 17 , the vehicle 10 of the present invention includes one or more processors 15 and a memory 17. The memory 17 stores a computer program. When the computer program is executed by the processor 15, the steps of the display method of any of the above embodiments are implemented.

[0098] For example, when the computer program is executed by the processor 15, it can implement:

[0099] 012: When lane-level data of a map and environmental data when the vehicle 10 is traveling on the current road are obtained, an environmental simulation screen is generated according to the lane-level data and the environmental data, and the environmental simulation screen displays a plurality of lanes corresponding to the current road;

[0100] 014: Generate bubble information 21 according to the navigation assistance information of the target location point;

[0101] 016: Integrate the bubble information 21 with the environmental simulation screen to generate a navigation simulation screen.

[0102] In the above vehicle 10, the user can know the navigation assistance information of the target location point through the bubble information 21, so as to facilitate the user to control the vehicle 10 and improve driving safety.

[0103] The computer-readable storage medium of the present invention stores a computer program thereon, and when the computer program is executed by the processor 15, the display method of any of the above embodiments is implemented.

[0104] For example, when the computer program is executed by the processor 15, it can implement:

[0105] 012: When lane-level data of a map and environmental data when the vehicle 10 is traveling on the current road are obtained, an environmental simulation screen is generated according to the lane-level data and the environmental data, and the environmental simulation screen displays a plurality of lanes corresponding to the current road;

[0106] 014: Generate bubble information 21 according to the navigation assistance information of the target location point;

[0107] 016: Integrate the bubble information 21 with the environmental simulation screen to generate a navigation simulation screen.

[0108] In the above computer-readable storage medium, the user can know the navigation assistance information of the target location point through the bubble information 21, so as to facilitate the user to control the vehicle 10 and improve driving safety.
