[0002] Car navigation is an intelligent in-vehicle positioning and route planning system designed for car driving scenarios. It uses positioning technologies such as the Global Positioning System (GPS) and Beidou to accurately obtain the real-time location of the vehicle.

[0077] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0078] Understandably, in existing technologies, car navigation technology mainly focuses on the independent navigation needs of individual vehicles. Its functional architecture and application scenarios are designed around this core. For the special scenario of convoy driving, there is often a lack of special adaptation and optimization. The navigation of each vehicle in the convoy usually operates independently, which cannot form close collaboration and information sharing, thus limiting the flexibility and safety of convoy driving.

[0079] To address the aforementioned issues, the intelligent automotive instrument navigation information overlay display method and system disclosed in this invention identifies multiple convoy vehicles and dynamically determines the leading and trailing vehicles from among them. The system overlays and displays information based on the navigation provided by the vehicle in front of and behind the convoy. When alternative routes are available, if the leading vehicle selects or travels to the alternative route, the system follows and switches the route display for the vehicle in front. The system receives abnormal monitoring data from the leading vehicle in front of the convoy, determines the abnormal location, and dynamically overlays and displays recommended obstacle avoidance lanes for the vehicle in front, while also capturing and transmitting abnormal monitoring data to the trailing vehicles. When the vehicle deviates from its route, the system generates and displays a convoy return route, selects the nearest vehicle in real time, and overlays and displays the reference for the return route for the vehicle in front. After the vehicle completes the route return, the leading and trailing vehicles in the convoy are re-determined. It can dynamically determine the leading and trailing vehicles in a convoy, and perform basic navigation overlay display, route following and switching display, dynamic overlay display of obstacle avoidance lane recommendations, and reference overlay display for regression. It is suitable for special scenarios of convoy driving, and can form collaboration and information sharing among multiple convoy vehicles, breaking the independent navigation of each vehicle and improving the flexibility and safety of convoy driving.

[0080] Specifically, Figure 1 A flowchart of the intelligent automotive instrument navigation information overlay display method provided by an embodiment of the present invention is shown.

[0081] In a preferred embodiment of the present invention, the intelligent vehicle instrument navigation information overlay display method specifically includes the following steps:

[0082] Step S101: Determine multiple vehicles in a convoy, and dynamically determine the leading vehicle and trailing vehicle from the multiple vehicles in the convoy. Display these vehicles on top of the convoy navigation provided by this vehicle.

[0083] In this embodiment of the invention, by acquiring convoy information, multiple convoy vehicles other than the vehicle itself are identified. During the convoy's operation, real-time positioning data of the vehicle and the multiple convoy vehicles is acquired. Based on the real-time positioning data, the vehicle in front of the vehicle and the vehicle behind the vehicle are dynamically identified from the multiple convoy vehicles. The positioning data of the vehicle in front and the vehicle behind the vehicle are extracted from the real-time positioning data. Then, on the vehicle's instrument navigation interface, the navigation is scaled according to the proximity distance between the vehicle and the vehicle in front and the vehicle behind the vehicle, so that the upper part of the instrument navigation interface can be visually overlaid with the positioning data of the vehicle in front, and the lower part of the instrument navigation interface can be visually overlaid with the positioning data of the vehicle behind, thus realizing the basic overlay display of navigation.

[0084] Understandably, dynamically determining the leading and trailing vehicles in a convoy means that when a vehicle's position in the convoy changes, it can automatically re-determine the leading and trailing vehicles in the convoy.

[0085] It is understood that, in this embodiment of the invention, the visualization and overlay display of the positioning data of the preceding vehicle and the following vehicle is based on the proximity distance between the preceding and following vehicles in the convoy and the vehicle itself. The icons of the preceding and following vehicles in the convoy are displayed on the instrument navigation interface, and the proximity distances are compared according to a preset standard convoy distance. Based on different comparison results, the icons of the preceding and / or following vehicles in the convoy are displayed in different colors, intuitively showing the following status to the driver. This allows the driver to adjust the driving speed according to different following statuses. For example, if the proximity distance of the preceding vehicle in the convoy does not exceed the standard convoy distance, the icon of the preceding vehicle in the convoy is displayed in green; if the proximity distance of the preceding vehicle in the convoy exceeds the standard convoy distance, the icon of the preceding vehicle in the convoy is displayed in red.

[0086] Specifically, Figure 2 A flowchart illustrating the basic overlay display for navigation in the method provided by an embodiment of the present invention is shown.

[0087] In another preferred embodiment of the present invention, the step of determining multiple platooned vehicles, dynamically determining the leading vehicle and the trailing vehicle from the multiple platooned vehicles, and overlaying and displaying the navigation of the leading vehicle and the trailing vehicle by the vehicle itself specifically includes the following steps:

[0088] Step S1011: Obtain fleet grouping information and identify multiple vehicles for the fleet.

[0089] Step S1012: During the driving process of this vehicle, obtain real-time positioning data of this vehicle and multiple vehicles in the convoy.

[0090] Step S1013: Based on the real-time positioning data, dynamically determine the leading vehicle and the trailing vehicle in the convoy from among the multiple convoyed vehicles.

[0091] Step S1014: Based on the real-time positioning data, the system overlays and displays the navigation data of the vehicle in front of the convoy and the vehicle behind the convoy.

[0092] Furthermore, the intelligent vehicle instrument navigation information overlay display method also includes the following steps:

[0093] Step S102: When there is an alternative driving route, if the vehicle in front of the convoy selects or drives to the alternative driving route, the vehicle will switch to follow the alternative driving route.

[0094] In this embodiment of the invention, when there is an alternative driving route, the alternative driving route will be displayed as a dashed line in the navigation of the vehicle and multiple convoy vehicles. During the convoy driving, if the vehicle in front of the convoy selects or drives to the alternative driving route, a route switching signal is generated and transmitted to the vehicle. Then, according to the route switching signal, the route is automatically switched on the navigation of the vehicle, so that the alternative driving route is displayed as a solid line in the navigation interface, while the previous route is displayed as a dashed line, realizing the route switching display of the vehicle.

[0095] Understandably, displaying route changes ensures consistency in fleet switching even when routes are being changed.

[0096] Specifically, Figure 3 A flowchart illustrating the route-following switching display in the method provided by an embodiment of the present invention is shown.

[0097] In another preferred embodiment of the present invention, when there is an alternative driving route, if the vehicle in front of the convoy selects or drives to the alternative driving route, the following steps are specifically included:

[0098] Step S1021: When there is an alternative driving route, the alternative driving route is displayed as a dashed line on this vehicle.

[0099] Step S1022: If the vehicle in front of the convoy selects or travels to an alternative route, a route switching signal is generated and transmitted to this vehicle.

[0100] Step S1023: According to the route switching signal, the route is switched and displayed in this vehicle.

[0101] Furthermore, the intelligent vehicle instrument navigation information overlay display method also includes the following steps:

[0102] Step S103: Receive the abnormal monitoring data of the preceding vehicle in the convoy, determine the abnormal location, dynamically overlay and display the recommended obstacle avoidance lane on this vehicle, and take pictures and transmit the abnormal monitoring data of this vehicle to the following vehicles in the convoy.

[0103] In this embodiment of the invention, by receiving abnormal monitoring data of the preceding vehicle transmitted by the preceding vehicle in the convoy, and then performing abnormal identification on the abnormal monitoring data to determine the abnormal location, and then performing lane-level obstacle avoidance analysis based on the abnormal location, a target obstacle avoidance lane that can avoid collision is selected, and the length of the road segment required to complete the obstacle avoidance is planned to determine the obstacle avoidance lane segment. Then, according to the target obstacle avoidance lane and the obstacle avoidance lane segment, the obstacle avoidance lane recommendation is dynamically overlaid and displayed on the instrument navigation interface of the vehicle. When the vehicle passes through the abnormal location, abnormal photography is performed to obtain the abnormal monitoring data of the vehicle. The abnormal monitoring data of the vehicle is then transmitted to the following vehicles in the convoy, and the following vehicles in the convoy can also perform the corresponding dynamic overlay display of obstacle avoidance lane recommendations.

[0104] Understandably, the dynamic overlay display of obstacle avoidance lane recommendations is based on the original route navigation, overlaying and enlarging the target obstacle avoidance lane and obstacle avoidance road segment. This allows drivers to intuitively determine how to adjust their driving lane and avoid obstacles (such as: fallen cargo, fallen tires, vehicles involved in accidents, etc.) in advance, thereby improving driving safety.

[0105] Specifically, Figure 4 A flowchart illustrating the dynamic overlay display of obstacle avoidance lane recommendations in the method provided by an embodiment of the present invention is shown.

[0106] In another preferred embodiment of the present invention, the steps of receiving the abnormal monitoring data of the preceding vehicle in the convoy, determining the abnormal location, dynamically overlaying and displaying the recommended obstacle avoidance lane for the vehicle, and capturing and transmitting the abnormal monitoring data of the vehicle to the following vehicles in the convoy specifically include the following steps:

[0107] Step S1031: Receive the abnormal monitoring data of the vehicle in front of the convoy.

[0108] Step S1032: Identify the anomaly in the monitoring data of the preceding vehicle and determine the location of the anomaly.

[0109] Step S1033: Based on the abnormal location, perform lane obstacle avoidance analysis and select the target obstacle avoidance lane and the corresponding obstacle avoidance lane segment.

[0110] Step S1034: Based on the target obstacle avoidance lane and the obstacle avoidance road segment, dynamically overlay and display the recommended obstacle avoidance lane on this vehicle.

[0111] Step S1035: When the vehicle passes through the abnormal location, take abnormal photos to obtain abnormal monitoring data of the vehicle.

[0112] Step S1036: Transmit the abnormal monitoring data of this vehicle to the vehicles in the convoy.

[0113] Furthermore, the intelligent vehicle instrument navigation information overlay display method also includes the following steps:

[0114] Step S104: When the vehicle deviates from the route, generate and display the team return route, select the nearest vehicle in real time, and overlay the reference for the return of the vehicle.

[0115] In this embodiment of the invention, by determining the current driving route of the vehicle, route positioning monitoring is performed based on the current driving route to determine whether the vehicle has deviated from the route. When a route deviation is determined, the current deviation position is determined, and a return position is selected from the current driving route. Then, based on the current deviation position and the return position, a group return route is planned and dynamically displayed on the vehicle's instrument panel navigation interface. Furthermore, based on real-time positioning data, the closest vehicle to the vehicle is selected from multiple group vehicles in real time, and the reference navigation data of the closest vehicle is obtained. The group return route and the reference navigation data are overlaid and merged on the vehicle's instrument panel navigation interface to achieve a reference overlay display for the return route, providing the driver with an intuitive display of the deviation situation and a reference for route return.

[0116] Specifically, Figure 5 A flowchart illustrating the reference overlay display during regression in the method provided by an embodiment of the present invention is shown.

[0117] In another preferred embodiment of the present invention, the step of generating and displaying a platoon return route when the vehicle deviates from its route, and selecting the nearest vehicle in real time for reference overlay display during the vehicle's return specifically includes the following steps:

[0118] Step S1041: Determine the current driving route of this vehicle.

[0119] Step S1042: Based on the current driving route, perform route positioning monitoring on the vehicle to determine whether the vehicle has deviated from the route.

[0120] Step S1043: When a route deviation occurs, select a return position from the current driving route.

[0121] Step S1044: Generate and display the team return route based on the return location.

[0122] Step S1045: Based on the real-time positioning data, select the nearest vehicle from the multiple platooned vehicles in real time.

[0123] Step S1046: Obtain the reference navigation data of the nearest vehicle.

[0124] Step S1047: Based on the platooning regression route, perform a reference overlay display on the reference navigation data in this vehicle.

[0125] Furthermore, the intelligent vehicle instrument navigation information overlay display method also includes the following steps:

[0126] Step S105: After the vehicle completes the route return, re-determine the leading vehicle and trailing vehicle in the convoy.

[0127] In this embodiment of the invention, after the vehicle arrives at the return position, it is determined that the vehicle has completed the route return. At this time, based on the real-time positioning data, the leading vehicle and the trailing vehicle in the platoon are re-determined from multiple platooned vehicles.

[0128] Specifically, Figure 6 The flowchart illustrating the re-determination of the leading and trailing vehicles in a platoon in the method provided by an embodiment of the present invention is shown.

[0129] In another preferred embodiment of the present invention, the step of re-determining the leading and trailing vehicles in the platoon after the vehicle completes its route return specifically includes the following steps:

[0130] Step S1051: When the vehicle arrives at the return position, it is determined that the vehicle has completed the route return;

[0131] Step S1052: Based on the real-time positioning data, re-determine the leading vehicle and trailing vehicle in the convoy.

[0132] Furthermore, Figure 7 The following is an application architecture diagram of the intelligent automotive instrument navigation information overlay display system provided in an embodiment of the present invention.

[0133] Specifically, in another preferred embodiment provided by the present invention, the intelligent automotive instrument navigation information overlay display system includes:

[0134] The basic overlay display module 101 is used to determine multiple convoy vehicles, dynamically determine the leading vehicle and the trailing vehicle from the multiple convoy vehicles, and perform basic overlay display for navigation of the leading vehicle and the trailing vehicle in this vehicle.

[0135] In this embodiment of the invention, the basic overlay display module 101 obtains convoy information to determine multiple convoy vehicles other than its own vehicle. During the convoy process, it obtains real-time positioning data of its own vehicle and the multiple convoy vehicles. Based on the real-time positioning data, it dynamically determines the convoy vehicle in front of its own vehicle and the convoy vehicle behind its own vehicle from among the multiple convoy vehicles. It extracts the positioning data of the vehicle in front of its own vehicle and the positioning data of the vehicle behind its own vehicle from the real-time positioning data. Then, in the instrument navigation interface of its own vehicle, it scales the navigation according to the proximity distance between its own vehicle and the vehicles in front and behind its own vehicle, so that the upper part of the instrument navigation interface can be visually overlaid with the positioning data of the vehicle in front, and the lower part of the instrument navigation interface can be visually overlaid with the positioning data of the vehicle behind, thus realizing the basic overlay display of navigation.

[0136] Specifically, Figure 8 A structural block diagram of the basic overlay display module 101 in the system provided by an embodiment of the present invention is shown.

[0143] The follow-up switching display module 102 is used to switch the route of the vehicle when there is an alternative driving route, and if the vehicle in front of the convoy selects or drives to the alternative driving route.

[0144] In this embodiment of the invention, when there is an alternative driving route, the follow-up switching display module 102 will display the alternative driving route as a dashed line in the navigation of the vehicle and multiple convoy vehicles. During the convoy driving of the vehicle and multiple convoy vehicles, if the vehicle in front of the convoy selects or drives to the alternative driving route, a route switching signal is generated and transmitted to the vehicle. Then, according to the route switching signal, the route is automatically switched on the navigation of the vehicle, so that the alternative driving route is displayed as a solid line in the navigation interface, while the previous route is displayed as a dashed line, realizing the follow-up switching display of the vehicle's route.

When the vehicle passes through the abnormal location, it takes an abnormal picture to obtain the abnormal monitoring data of the vehicle, and then transmits the abnormal monitoring data of the vehicle to the following vehicles in the convoy. The following vehicles in the convoy can also perform the corresponding dynamic overlay display of obstacle avoidance lane recommendations.

[0147] Specifically, Figure 9 The diagram shows a structural block diagram of the lane recommendation display module 103 in the system provided by an embodiment of the present invention.

Claims

1. A method for superimposed display of navigation information on an intelligent automobile instrument, characterized in that, The method specifically includes the following steps: Multiple vehicles in a convoy are identified, and the leading and trailing vehicles in the convoy are dynamically determined from among the multiple vehicles in the convoy. The vehicles in the convoy are then overlaid and displayed on the basis of the navigation provided by the vehicle in front of the convoy and the vehicles in the convoy. By acquiring convoy information, multiple vehicles in the convoy besides the vehicle itself are identified. During convoy travel between the vehicle and these vehicles, real-time location data of the vehicle and the convoy is acquired. Based on this real-time location data, the vehicle in front of the vehicle and the vehicle behind the vehicle in the convoy are dynamically identified. The location data of the vehicle in front and the vehicle behind the vehicle are extracted from the real-time location data. Then, on the vehicle's instrument panel navigation interface, the navigation is scaled according to the proximity of the vehicle to the vehicle in front and the vehicle behind, allowing the location data of the vehicles in front to be visually overlaid and displayed at the top of the instrument panel navigation interface. The lower part of the screen can visually overlay and display the location data of the following vehicles, realizing the basic overlay display of navigation; in the instrument navigation interface, the icons of the vehicles in front and behind the convoy are displayed, and the proximity distance is compared according to the preset standard convoy distance. Based on different comparison results, the icons of the vehicles in front and / or behind the convoy are displayed with different colors, intuitively showing the following status to the driver, so that the driver can adjust the driving speed according to different following statuses. Specifically: if the proximity distance of the vehicle in front of the convoy does not exceed the standard convoy distance, the icon of the vehicle in front of the convoy is displayed in green; if the proximity distance of the vehicle in front of the convoy exceeds the standard convoy distance, the icon of the vehicle in front of the convoy is displayed in red. When there is an alternative driving route, if the vehicle in front of the convoy selects or drives to the alternative driving route, the vehicle will switch to follow the alternative driving route. Receive abnormal monitoring data of the vehicle in front of the convoy, determine the abnormal location, dynamically overlay and display the recommended obstacle avoidance lane in this vehicle, and take pictures and transmit the abnormal monitoring data of this vehicle to the vehicle behind the convoy. When the vehicle deviates from its route, a convoy return route is generated and displayed, and the nearest vehicle is selected in real time for reference overlay display during the return process. By determining the vehicle's current driving route, the system monitors the vehicle's location to determine if it has deviated from the route. If deviation is detected, the system identifies the current deviation position and selects a return position from the current driving route. Based on the current deviation and return positions, the system plans a group return route and dynamically displays it on the vehicle's instrument panel navigation interface. Furthermore, based on real-time positioning data, the system selects the closest vehicle from multiple group vehicles and obtains its reference navigation data. This data is then overlaid and integrated on the vehicle's instrument panel navigation interface, providing a reference overlay display for the return route. This provides the driver with a clear view of the deviation and a reference for route return. After this vehicle completes its route return, the leading and trailing vehicles in the convoy will be reassigned.
