[0025] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0026] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0027] Based on digital maps, vehicle navigation, automatic driving and other functions can be realized. Due to the frequent construction of urban infrastructure, the resources consumed in collecting and making digital maps are huge. If the vehicle does not download the latest digital map in time, it will bring safety hazards to the vehicle's navigation, automatic driving, etc. In addition, the road conditions of the road section may change at any time, and it is difficult to update the digital map at any time every day. Therefore, how to enable the vehicle to complete automatic driving on these sections when the road conditions of the section change frequently and the digital map needs to be updated has become an urgent problem to be solved.

[0028] In order to solve the above problems, the embodiments of the present disclosure provide a vehicle navigation method, apparatus, device, medium and vehicle.

[0029] Figure 1 The flowchart of a vehicle navigation method provided by the embodiment of the present disclosure can be executed by a vehicle navigation device, a navigation device in a vehicle, etc., wherein the vehicle navigation device can be implemented by software and / or hardware, and can generally be integrated in an electronic device, and the vehicle navigation device and / or electronic device can be configured in a vehicle. Figure 1 As shown, the method includes:

[0030] Step 101, when the target vehicle is navigating according to the initial digital map, if the target vehicle obtains a traffic update mark of a traffic update section, then the update information of the traffic update section is downloaded according to the traffic update mark; wherein the traffic update section is the section that the target vehicle is about to enter.

[0031] The target vehicle may be a moving vehicle, and this embodiment does not limit the energy supply type of the target vehicle, for example, the energy supply type of the target vehicle may be pure electric power or hybrid power, etc. This embodiment does not limit the type of the target vehicle, for example, the type of the target vehicle may be a sport utility vehicle (SUV) or a sedan, etc.

[0032] The target vehicle may be equipped with a device or apparatus having the function of collecting images of the vehicle's exterior. In one embodiment of the present application, the target vehicle may be equipped with an image sensor, which may be used to collect images of one or more directions of the vehicle's exterior. For example, the image sensor may collect images in the direction of the vehicle's travel, in the opposite direction of the vehicle's travel, or in the directions of both sides of the vehicle, etc. In the embodiment of the present application, there is no restriction on the direction in which the image sensor collects images.

[0033] This embodiment does not limit the image sensor. For example, the image sensor may be a vehicle-mounted camera specifically used to collect road condition update signs, or the image sensor may be a sensor with image acquisition function in a vehicle's automatic driving system, an Around View Monitor (AVM) system, or other systems.

[0034] A digital map is also called an electronic map. The digital map may be a map that is stored and consulted in digital form using computer technology. This embodiment does not limit the type of the digital map. For example, the digital map may be a high-precision map, which is a high-precision map used for autonomous driving. The high-precision map may include information such as road shapes and traffic signs. The initial digital map may be the original version of the map used by the target vehicle. In the initial digital map, the road condition information of the road condition update section is not updated in time, and the road condition of the road condition update section in the initial digital map is inconsistent with the actual road condition. In an optional implementation, the initial digital map may be an initial high-precision map.

[0035] The road section may be a section of road, and the road section may include an intersection. The road condition update section may be a section where the road condition has changed, and the latest road condition of the road condition update section is not recorded in the initial digital map. In an optional implementation, after the road condition of the road condition update section has changed, the target vehicle has not passed through the section, and the probability that the target vehicle will pass through the section is greater than a preset passing threshold. The road condition update identifier may be an identifier corresponding to the road condition update section one by one, and the road condition update identifier may be a road condition update code. This embodiment does not limit the specific type of the road condition update code, for example, the type of the road condition update code may be a QR code. This embodiment does not limit the setting method of the road condition update identifier, for example, the road condition update identifier may be set on one or more of a traffic sign, a traffic sign, an electronic screen, and a road surface. The update information is also called the road condition update information. The update information may be the road condition information corresponding to the road section after the road condition of the road condition update section changes. The update information may include at least one of: lane information, guidance information, speed information, traffic light information, road sign information, avoidance information, and road section digital map.

[0036] In the disclosed embodiment, the road condition update mark can be a road condition update QR code, and the target vehicle can travel under the navigation of the initial digital map by manual operation or automatic driving. The target vehicle can be equipped with an image sensor, through which the target vehicle can collect images of the environment outside the vehicle in real time to obtain an environmental image. The vehicle navigation device can obtain the application map mark of the digital map currently taken by the vehicle, and compare the application map mark with the initial map mark corresponding to the initial digital map. If the application map mark is consistent with the initial map mark, it means that the target vehicle is navigating under the guidance of the initial digital map. Before the target vehicle enters the road condition update section, the vehicle navigation device can recognize the environmental image collected by the image sensor in real time through the optical character recognition (OCR) technology, and determine whether there is a road condition update QR code in the environmental image. If so, the download link corresponding to the road condition update QR code is accessed, and then the update information corresponding to the road condition update section is downloaded.

[0037] Step 102 : Navigate the target vehicle based on the updated information and the initial digital map.

[0038] In the disclosed embodiment, after the update information of the road condition update section is determined by the road condition update identifier, the target vehicle is navigated according to the update information and the original initial digital map.

[0039] The vehicle navigation method provided by the disclosed embodiment includes: during the process of the target vehicle navigating according to the initial digital map, if the target vehicle obtains the road condition update mark of the road condition update section, then downloading the update information of the road condition update section according to the road condition update mark; wherein the road condition update section is the road condition update section that the target vehicle is about to enter; navigating the target vehicle based on the update information and the initial digital map. In the disclosed embodiment, when the target vehicle is about to enter the road condition update section, the road condition update mark of the road condition update section is collected, and the updated road condition information is obtained based on the road condition update mark, and then the vehicle is navigated based on the updated road condition information and the original digital map, so that the road condition corresponding to the digital map of the vehicle entering the road condition update section is consistent with the actual road condition, thereby improving the safety of the vehicle.

[0040] In some embodiments of the present disclosure, the update information includes: at least one of lane information, guidance information, speed information, traffic light information, road sign information, and avoidance information.

[0041] Accordingly, based on the update information and the initial digital map, the target vehicle is navigated, including: updating the initial road information in the initial digital map according to the update information to obtain an updated digital map; wherein the initial road information is the road information corresponding to the road condition update section in the initial digital map, and the updated digital map includes the road information of the road condition update section corresponding to the update information; and navigating the target vehicle according to the updated digital map.

[0042] Figure 2 A flow chart of another vehicle navigation method provided by an embodiment of the present disclosure is shown as follows: Figure 2 As shown, the vehicle navigation method includes:

[0043] Step 201, during the process of the target vehicle navigating according to the initial digital map, if the target vehicle obtains a road condition update mark of a road condition update section, then the update information of the road condition update section is downloaded according to the road condition update mark; wherein the road condition update section is the road condition update section that the target vehicle is about to enter, and the update information includes: at least one of lane information, guidance information, speed information, signal light information, road sign information, and avoidance information.

[0044] The lane information may be information characterizing the characteristics of the lane, and the lane information may include at least one of lane position information and lane type information. The lane position information may characterize the position of the edge line of the roadway, and the lane position information may include the longitude and latitude information of multiple position points on the edge line of the roadway; the lane type information may characterize the type of the edge line of the roadway, and the lane type information may include: solid white line, dashed white line, double yellow line, etc. The guidance information may be information characterizing the corresponding direction of the lane guide line in the lane, and the driving direction of the vehicle in each lane may be determined based on the guidance information, and the guidance information may include but is not limited to: straight driving information, left turn information, etc. The speed information may be information characterizing the speed limit of the vehicle, and the speed information may include but is not limited to: speed limit information and / or speed limit cancellation information.

[0045] The signal light information may be information indicating the current traffic state of the traffic light, and the signal light information includes but is not limited to: at least one of prohibited traffic information, permitted traffic information, and warning information. The road sign information is also called road traffic sign information, and the road sign information may include road traffic sign information for indication and / or road traffic sign information for warning. The avoidance information may be information instructing the vehicle to avoid. This embodiment does not limit the number of lanes corresponding to the avoidance information. For example, the number of lanes corresponding to the avoidance information may be one or more.

[0046] The road condition update mark corresponding to the lane information is the lane mark, the road condition update mark corresponding to the guidance information is the guidance mark, the road condition update mark corresponding to the speed information is the speed mark, the road condition update mark corresponding to the signal light information is the signal light mark, the road condition update mark corresponding to the road sign information is the road sign mark, and the road condition update mark corresponding to the avoidance information is the avoidance mark.

[0047] In this embodiment, the road condition change in the road condition update section is small, and the small road condition change can be recorded through the update information. After the vehicle navigation device determines the update mark, it downloads the update information corresponding to the update mark. It should be noted that the road condition update mark corresponding to the information with a high frequency of change, such as the traffic light information, can be displayed in the form of an electronic screen to facilitate the modification of the road condition update mark.

[0048] Step 202, updating the initial road information in the initial digital map according to the update information to obtain an updated digital map; wherein the initial road information is the road information corresponding to the road condition update section in the initial digital map, and the updated digital map includes the road information of the road condition update section corresponding to the update information.

[0049] The updated digital map may be understood as a digital map whose road condition is consistent with the actual road condition of the road section where the road condition is updated. The initial road information may be information representing the original road condition of the road section where the road condition is updated. The initial road information may be all or part of the road information corresponding to the road section where the road condition is updated in the initial digital map. The road condition dimension represented by the initial road information is consistent with that represented by the updated information. For example, the initial road information and the updated information may both be lane information.

[0050] In the disclosed embodiment, the vehicle navigation device can determine the initial road information corresponding to the road condition update section in the initial digital map, and replace the initial road information with the update information to obtain the updated digital map. In some embodiments, if the initial road information is empty, the empty initial road information is replaced with the update information. For example, if there is no speed limit in the road condition update section originally, and there is a speed limit in the road condition update section after the update, the initial road information and the update information are both speed information, and the initial road information representing the original road condition is empty.

[0051] In some embodiments of the present disclosure, lane information includes avoidance information, which is information indicating that a road section is closed after a road condition update. The editor of the avoidance information may include a road construction party and / or an accident occurrence party, where the road construction party is the party carrying out the road construction, and the accident occurrence party is the person who has a traffic accident.

[0052] In this embodiment, when road construction is being carried out, one or more lanes need to be closed. The road construction party can edit the section location information, closure time information and other information of the road condition update section that needs to be closed, and summarize the section location information, closure time information and other information into avoidance information, and generate an avoidance sign corresponding to the avoidance information, so that vehicles that are about to pass through the road condition update section can scan the avoidance sign and then detour to avoid the road condition update section.

[0053] Similarly, in the event of a traffic accident, one or more lanes are blocked due to the occupation of the accident vehicle. The party where the accident occurred can edit the section location information, closure time information, etc. of the road condition update section that is blocked, and summarize the section location information, closure time information, etc. into avoidance information, and generate an avoidance sign corresponding to the avoidance information, so that vehicles about to pass through the road condition update section can scan the avoidance sign and then detour to avoid the road condition update section.

[0054] Step 203: Navigate the target vehicle according to the updated digital map.

[0055] In this embodiment, after the initial digital map is adjusted according to the update information to obtain an updated digital map, the target vehicle is navigated by manual control or automatic driving according to the updated digital map.

[0056] Optionally, in some embodiments of the present disclosure, the section between the location where the traffic condition update mark is set and the exit of the traffic condition update section can be determined as a passable section, the average time for vehicles to pass through the passable section is determined, and the pass time greater than the average time is determined, and the navigation of the target vehicle according to the updated digital map is used as the starting time. After the pass time has passed at the starting time, the updated digital map is switched to the initial digital map, and the target vehicle is navigated by the initial digital map. In this way, the temporary vehicle condition occurring in the section is prevented from affecting the subsequent vehicles when they pass through the section again, and the driving safety of the vehicle is improved.

[0057] In the above scheme, the initial digital map is updated according to the update information to obtain an updated digital map, and the target vehicle is navigated according to the updated digital map. This scheme is suitable for scenarios where the road conditions change slightly or the road conditions change frequently. It can make the road conditions corresponding to the digital map used by the target vehicle consistent with the actual road conditions, thereby improving the safety of vehicle driving.

[0058] In some embodiments of the present disclosure, the update information includes: a road segment digital map corresponding to the road condition update section.

[0059] Accordingly, the target vehicle is navigated based on the update information and the initial digital map, including: when the target vehicle is navigating according to the initial digital map, if an entrance mark of the road condition update section is obtained, the initial digital map is switched to a road section digital map; and navigation is performed according to the road section digital map.

[0060] Correspondingly, the vehicle navigation method further includes: if the target vehicle obtains the exit mark of the road condition update section, switching the road section digital map to the initial digital map, and navigating the target vehicle exiting the road condition update section according to the initial digital map.

[0061] Figure 3 A flow chart of another vehicle navigation method provided by an embodiment of the present disclosure is shown as follows: Figure 3 As shown, the vehicle navigation method includes:

[0062] Step 301, when the target vehicle is navigating according to the initial digital map, if the target vehicle obtains a traffic update mark of a road section with traffic update, then the update information of the road section with traffic update is downloaded according to the traffic update mark; wherein the road section with traffic update is the road section that the target vehicle is about to enter, and the update information includes: a road section digital map corresponding to the road section with traffic update.

[0063] The road section digital map may be a digital map of the road section area where the road condition is updated, and the road condition corresponding to the road section digital map is consistent with the actual road condition of the updated road section area. If the initial digital map is an initial high-precision map, the road section digital map is a road section high-precision map.

[0064] In this embodiment, due to the large change of road conditions in the road condition update section, or the re-surveying of the road condition update section, the complete digital map of the road condition update section is recorded by the road section digital map. After the vehicle navigation device determines the update mark, the road section digital map corresponding to the update mark is downloaded.

[0065] Step 302: When the target vehicle is navigating according to the initial digital map and an entrance mark of a road section with updated road conditions is obtained, the initial digital map is switched to a road section digital map.

[0066] The entrance sign may be a sign corresponding to the entrance of the road section where the traffic is updated, and the entrance sign indicates that the vehicle is about to pass the entrance of the road section where the traffic is updated, and enter the road section where the traffic is updated. This embodiment does not limit the location of the entrance sign, for example, the entrance sign may be set at the entrance of the road section where the traffic is updated, or the entrance sign may be set within the road section where the traffic is updated, and the distance between the entrance sign and the entrance of the road section where the traffic is updated may be determined based on the distance at which the vehicle can successfully perform OCR recognition at the entrance of the road section where the traffic is updated.

[0067] In this embodiment, after the download of the road section digital map is completed, the target vehicle still navigates according to the initial digital map. At the same time, the image sensor of the target vehicle continues to automatically capture the environment image and recognize the environment image. If the entrance sign of the road condition update section is recognized, it means that the vehicle is about to enter the road condition update section. Since the road condition of the road condition update section in the initial digital map is inaccurate, the target vehicle is no longer navigated according to the initial digital map, and the initial digital map is switched to the road section digital map.

[0068] Step 303: Navigate and drive according to the digital map of the road section.

[0069] In this embodiment, after the map used for vehicle navigation is switched from the initial digital map to the road section digital map, the target vehicle navigates according to the road section digital map.

[0070] Step 304: If the target vehicle obtains the exit mark of the road section with updated traffic conditions, the road section digital map is switched to the initial digital map, and the target vehicle is navigated out of the road section with updated traffic conditions according to the initial digital map.

[0071] The exit sign may be a sign corresponding to the exit of the road section where the traffic is updated, and the exit sign indicates that the vehicle is about to pass the exit of the road section where the traffic is updated, and is away from the road section where the traffic is updated. This embodiment does not limit the location of the exit sign, for example, the exit sign may be set at the exit of the road section where the traffic is updated, or the exit sign may be set outside the road section where the traffic is updated, and the distance between the exit sign and the exit of the road section where the traffic is updated may be determined based on the distance at which the vehicle can successfully perform OCR recognition at the exit of the road section where the traffic is updated.

[0072] In the above scheme, the road condition of the updated section is recorded by the section digital map. By alternating the section digital map with the initial digital map, the road condition recorded by the map used by the vehicle is consistent with the actual road condition, thereby improving the safety of vehicle driving.

[0073] Next, the vehicle navigation method in the embodiment of the present disclosure is described through a specific example.

[0074] In this example, the road condition update identifier may be a road condition update QR code, which may correspond to road condition update information including traffic information, and the road condition update QR code may be set on the road surface. During the driving process of the target vehicle, the on-board camera automatically captures the image, and the road condition update QR code is extracted from the captured environmental image using OCR technology. By using the road condition update QR code corresponding to the road condition update information, the recognition and navigation capabilities of the autonomous driving can be improved, thereby improving the accuracy and efficiency of the autonomous driving.

[0075] The traffic condition update information may include one or more of the following information.

[0076] Lane position information, which records the position of the lane boundary. The lane position information can be obtained by scanning the lane position mark of the lane position information. Automatic driving based on the lane position information can enable the vehicle to drive within the lane more accurately.

[0077] Guidance information, the road condition update mark corresponding to the guidance information is a guidance mark, and the guidance mark can correspond to the vehicle's driving direction one by one. The guidance mark can be set in a more conspicuous location such as a signboard, a road sign, or the center of a city. The guidance information can be obtained by scanning the guidance mark. During the process of automatic driving, the vehicle can automatically navigate based on the guidance information.

[0078] Speed ​​information, which may be speed limit information. The road condition update mark corresponding to the speed limit information is a speed limit mark. Automatically obtaining the speed limit information by scanning the speed limit mark can enable the vehicle to automatically adapt to the updated road conditions, thereby reducing the possibility of speeding and the like.

[0079] Signal light information, also known as traffic light information, corresponds to a traffic light sign, which is a road condition update sign. The signal light sign can be set on the display screen at the intersection in the form of an electronic QR code. The signal light sign can be changed in real time according to demand to direct traffic. The traffic light sign can be bound to the lane. If a vehicle scans the signal light sign to determine the corresponding signal light information, the vehicle is determined to move forward or stop according to the signal light information.

[0080] Road sign information, road sign information is also called special road sign information. The road condition update mark corresponding to the road sign information is the road sign mark. By scanning the road sign mark, road sign information related to the road sign can be obtained. The road sign information includes but is not limited to: road safety reminder information, bus lane information, etc.

[0081] It should be noted that the above-mentioned road condition update information can be prompted through a human-machine interface (Human Machine Interface, HMI).

[0082] In the above scheme, by scanning the QR code, the self-driving vehicle becomes more intelligent and efficient, which improves the driving safety of the vehicle, avoids the vehicle's driving route errors caused by incorrect road conditions, and saves the vehicle's energy and traffic time.

[0083] In another optional implementation, a traffic condition update mark (i.e., the first two-dimensional code), an entrance mark (i.e., the second two-dimensional code), and an exit mark (i.e., the third two-dimensional code) of the traffic condition update section can be set respectively. Specifically, the traffic condition update mark can be set N meters before entering the traffic condition update section, where N is a positive integer. The entrance mark can be set at the entrance of the traffic condition update section. The exit mark can be set at the exit of the traffic condition update section.

[0084] The traffic condition update mark corresponds to the download information of the high-definition map of the road section with the traffic condition update. When the vehicle collects the traffic condition update mark through the image sensor, the high-precision map of the road section with the traffic condition update is downloaded according to the download information.

[0085] The entrance mark is used to enable the vehicle to switch the high-precision map used in autonomous driving from the initial high-precision map to the high-precision map of the road section with the road condition update. When the vehicle passes through the entrance of the road section with the road condition update and captures the entrance mark through the image sensor, the vehicle navigation device will switch the high-precision map used in autonomous driving to the high-precision map of the road section with the road condition update. After that, the vehicle can use the high-precision map of the road section for autonomous driving when driving in the road section with the road condition update.

[0086] The exit sign is used to enable the vehicle to switch the high-precision map used in autonomous driving from the high-precision map of the road section with the road condition update back to the initial high-precision map. When the vehicle passes the exit of the road section with the road condition update and captures the exit sign through the image sensor, the vehicle navigation device will switch the high-precision map used in autonomous driving back to the initial high-precision map.

[0087] In the above scheme, frequent updates of high-precision maps in the vehicle are avoided. When there is construction on a road section, the update information consistent with the actual road conditions is obtained through the road condition update mark, so that the vehicle can use the automatic driving function to pass through the road section without updating the version of the high-precision map. In addition, in the present application, when the vehicle is about to enter the road condition update section, the update information is downloaded and used when the vehicle enters the road condition update section, and the utilization rate of the update information is relatively high. In the related art, if a high-precision map is updated for multiple sections at one time, the multiple sections are not associated with the section entered by the target vehicle, and the possibility of the vehicle entering the multiple sections is relatively small, and the utilization rate of the updated information is relatively low.

[0088] In addition, traffic signs are displayed in the form of QR codes, which have high recognizability, reducing the time spent on understanding or identifying traffic signs through image processing, and also reducing the occurrence of misreading. Autonomous vehicles can more accurately identify road rules such as speed limits and traffic lights, allowing vehicles to maintain appropriate speeds and distances, improving driving safety.

[0089] Figure 4 A schematic structural diagram of a vehicle navigation device provided by an embodiment of the present disclosure is shown.

[0090] In some embodiments of the present disclosure, Figure 4 The vehicle navigation device shown can be executed by an electronic device or a server. The electronic device may include but is not limited to mobile terminals such as smart phones, laptops, personal digital assistants (PDAs), tablet computers (PADs), portable multimedia players (PMPs), vehicle terminals (such as vehicle navigation terminals), wearable devices, etc., and fixed terminals such as digital TVs, desktop computers, smart home devices, etc. The server can be a server cluster or a cloud server.
