Description

Technical Field

[0001] The present application relates to the field of intelligent driving technology, and in particular to a method, device, equipment and storage medium for controlling a navigation-assisted driving function. Background Art

[0002] With the rapid development of internet technology bringing revolutionary changes to the automotive industry, intelligent control technology has also rapidly advanced in automotive applications. Intelligent driving systems are also requiring vehicles' navigation and driving assistance functions to be able to handle increasingly complex traffic scenarios. Because intelligent driving technology is limited by its perception capabilities, it cannot guarantee that intelligent vehicles can operate safely in all road conditions and weather conditions. Therefore, it is necessary to predefine the operating range of navigation and driving assistance functions based on the technical capabilities of the intelligent driving system. Then, the navigation and driving assistance functions should be controlled within this operating range. By limiting its usage environments, the user experience of navigation and driving assistance functions can be improved.

[0003] At present, the determination of operating range information in related technologies is highly dependent on high-precision maps. Since high-precision maps may contain errors or discontinuous fragments, when users use the navigation driving assistance function, the intelligent driving system cannot well control the activation and exit of the navigation driving assistance function, which may easily lead to the occurrence of misactivation of the function, too short a usable range, frequent entry and exit, etc., affecting the user experience.

[0026] The following will describe the embodiments of the present application with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand the other advantages and effects of the present application from the contents disclosed in this specification. The present application can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present application. It should be understood that the preferred embodiments are only for the purpose of illustrating the present application and are not intended to limit the scope of protection of the present application.

[0027] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present application. Therefore, the illustrations only show components related to the present application and are not drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component can be changed at will, and the component layout type may also be more complicated.

[0028] In the following description, a large number of details are discussed to provide a more thorough explanation of the embodiments of the present application. However, it is obvious to those skilled in the art that the embodiments of the present application can be implemented without these specific details. In other embodiments, well-known structures and devices are shown in the form of block diagrams rather than in detail to avoid making the embodiments of the present application difficult to understand.

[0029] Currently, the determination of the operating range information of the navigation-assisted driving function is highly dependent on high-precision maps. Since intelligent driving technology is limited by its perception capabilities, it cannot guarantee that intelligent driving vehicles can drive safely in all road conditions and weather conditions. Therefore, it is necessary to set the operating range of the navigation-assisted driving function in advance based on the technical capabilities of the intelligent driving system, and then control the navigation-assisted driving function based on the operating range. By limiting its usage environment, the user's experience of the navigation-assisted driving function can be improved. However, the inventors of this application have discovered that because high-precision maps may contain erroneous or discontinuous segments, that is, they do not match the real-time environmental information, the intelligent driving system cannot effectively control the activation and exit of the navigation-assisted driving function when the user uses it. This can easily lead to situations such as the navigation-assisted driving function being mistakenly activated, the usable range being too short, and frequent entry and exit, which affects the user's driving experience.

[0030] To solve the above problems, the present invention provides a method for controlling navigation-assisted driving functions. Figure 1 , Figure 1 FIG. 1 is a schematic diagram of an implementation environment of a navigation-assisted driving function control device according to an exemplary embodiment of the present application. Figure 1 As shown, the implementation environment includes a vehicle 101 and a control device 102, wherein the control device 102 is embedded in the vehicle 101 and is used to control the activation and exit of the navigation driving assistance function in the vehicle 101. The control device 102 includes but is not limited to a vehicle system, an on-board computer, etc., and corrects the initial operating range and the initial distance of the vehicle from the end of the operating range in the initial operating range information of the navigation driving assistance function determined based on the high-precision map through the real-time environmental information collected by the vehicle, so that the obtained corrected operating range information can more accurately reflect the operating range of the navigation driving assistance function, thereby achieving precise control of the activation and exit of the navigation driving assistance function, effectively solving the problems of incorrect activation of the navigation driving assistance function, too short a usable range, frequent entry and exit, etc. due to possible errors or discontinuous fragments in the high-precision map, thereby improving the user's driving experience.

[0031] See Figure 2 , Figure 2 This is a flow chart of a method for controlling a navigation-assisted driving function according to an exemplary embodiment of the present application. Figure 1 It should be understood that the method can also be applied to other exemplary implementation environments and be specifically executed by devices in other implementation environments, and this embodiment does not limit the implementation environment to which the method is applicable.

[0032] like Figure 2As shown, in an exemplary embodiment, the navigation-assisted driving function control method includes at least steps S210 to S250, which are described in detail as follows:

[0033] Step S210: Obtain the current road information and road change information of the vehicle in the high-precision map.

[0034] The current road information includes the current vehicle position and the current road type, and the road change information includes the road type ahead, the road change type, and the length of the road type change. The current vehicle position is the vehicle's current location, which can be considered the vehicle's real-time location during driving. The current road type is the road type at the current vehicle position, such as urban road, ramp, highway, and urban expressway. The road type ahead is the road type that needs to be determined when the road ahead is inconsistent with the current road type in the vehicle's driving path. It can include the road type at the first position ahead and the road type at the second position ahead. The road change type refers to the change between the current road type and the road type ahead, from road type A to road type B. For example, if the current road type is a highway and the road type ahead is an urban expressway, the road change type in this case is from highway to urban expressway. The road change type can also include the first road change type and the second road change type. The road type change length is the connection distance or transition distance when changing between road types A and B.

[0035] See Figure 3 , Figure 3 This is a schematic diagram of road change information shown in an exemplary embodiment of the present application. Figure 3 As shown, the current road type is urban road, the road type at the first position ahead is a ramp, the road type at the second position ahead is an urban expressway, the first road change type is from urban road to ramp, and the second road change type is from ramp to urban expressway. The length of the road type change is the dotted part of the middle line, which is the connection distance between the urban road and the ramp, and the connection distance between the ramp and the urban expressway, respectively.

[0036] Step S220 : determining the initial operating range information of the navigation-assisted driving function of the vehicle based on the current road information and the road change information.

[0037] Among them, the initial operating range information includes the initial operating range and the initial distance of the vehicle from the end point of the operating range. The initial operating range refers to the setting range of the vehicle's navigation driving assistance function, that is, on which road sections the navigation driving assistance function can be activated. It should be noted that the setting range of the navigation driving assistance function includes expressways, urban expressways, ramps between expressways, ramps between expressways and urban expressways, ramps between urban expressways and urban expressways, ramps between expressways and urban roads, and ramps between urban expressways and urban roads. The initial distance of the vehicle from the end point of the operating range refers to the length from the vehicle's current position to the end of the current road type plus the length of the road type change.

[0038] In one embodiment, the initial operating range information of the vehicle's navigation-assisted driving function is determined based on current road information and road change information, including: judging whether the vehicle is in the initial operating range based on the current road information; if the vehicle is in the initial operating range, determining the initial distance based on the current vehicle position and the length of the road type change.

[0039] It should be noted that determining whether the vehicle is in the initial operating range based on the vehicle's current road information specifically refers to determining whether the vehicle is in the initial operating range based on the vehicle's current position and the current road type. Figure 4 , Figure 4 FIG. 1 is a schematic diagram showing an exemplary embodiment of the present application showing the initial distance of a vehicle from the end point of the operating range. Figure 4 As shown in Figure 1, the vehicle is currently located on the urban expressway and can be considered to be in the initial operating range. When the vehicle is in the initial operating range, the initial distance is determined based on the length S1 from the vehicle's current position to the end of the urban road and the length S2 of the ramp to the urban road, as shown in Figure 1. Figure 4 , initial distance = S1 + S2.

[0040] Step S230 , correcting the initial operating range information based on the real-time environmental information collected by the vehicle to obtain corrected operating range information.

[0041] Taking into account that high-precision maps may contain errors or discontinuous fragments, that is, they are inconsistent with real-time or temporary environmental information, which will affect the accuracy of the initial operating range information, it is necessary to correct the initial operating range information based on the real-time environmental information collected by the vehicle to ensure the readiness of the operating range information. When using the navigation driving assistance function, users can achieve precise control over the activation and exit of the navigation driving assistance function to avoid situations such as incorrect activation of the navigation driving assistance function, too short a usable range, frequent entry and exit, etc.

[0042] In one embodiment, initial operating range information is corrected based on real-time environmental information collected by the vehicle to obtain corrected operating range information, including: comparing the real-time environmental information with the initial operating range information to determine the operating range to be corrected in real time; identifying target obstacles in the real-time environmental information, where the target obstacles include dynamic obstacles and stationary obstacles; correcting the operating range to be corrected based on the target obstacles to obtain a corrected operating range, and determining whether the vehicle is within the corrected operating range; and correcting the initial distance based on the target obstacle to obtain a corrected distance.

[0043] It should be noted that the real-time environmental information is only the environmental conditions around the vehicle, while the initial operating range information determined based on the high-precision map involves environmental information within a large range of the vehicle's driving path. Therefore, after obtaining the initial operating range information and the real-time environmental information, the vehicle compares the two to obtain the operating range to be corrected, where the operating range to be corrected can be understood as the road section around the vehicle. Then, the target obstacles in the real-time environmental information are identified, where the target obstacles include dynamic and static obstacles, such as vehicles, pedestrians, buildings, etc. Of course, the target obstacles can also be temporary conditions on the road, such as traffic accidents, road repairs, etc. The target obstacles will affect the operating range information of the navigation driving assistance function. Therefore, the operating range to be corrected and the initial distance are corrected based on the target obstacles to determine whether the current position of the vehicle is in the corrected operating range and obtain the corrected distance.

[0044] In one embodiment, the initial operating range information is corrected based on real-time environmental information collected by the vehicle. Before obtaining the corrected operating range information, the process also includes: determining whether the initial distance between the vehicle and the end point of the operating range can be determined based on the type of road ahead and the length of the road type change; if the initial distance cannot be determined, using the operating range distance threshold as the initial distance.

[0045] Due to the limited perception capabilities of the vehicle's intelligent driving system, it may be impossible to determine the type of road ahead and the length of the road type change, and thus the initial distance of the end point of the vehicle's operating range cannot be determined. In order to ensure the normal activation, operation or exit of the navigation driving assistance function, the operating range distance threshold is used as the initial distance. Among them, the operating range distance threshold can be understood as the maximum distance over which the navigation driving assistance function can continue to operate.

[0046] Please refer to Table 1, which shows the logic for determining whether the vehicle is within the corrected operating range and the distance from the end of the operating range (i.e., the corrected distance) based on current road information and road change information, according to an embodiment of the present application. It should be noted that Table 1 only lists some possible situations and does not represent all possible situations in the embodiments of the present application.

[0047] Table 1

[0048] The “ / ” in Table 1 indicates that due to the limited perception capability of the vehicle's intelligent driving system, the type of road ahead may not be determined; the first corrected distance represents the corrected distance between the vehicle's current position and the road type at the first position ahead, and the second corrected distance represents the corrected distance between the vehicle's position on the first road type ahead and the road type at the second position ahead.

[0049] Step S240 : judging the activation condition or exit condition of the navigation-assisted driving function based on the corrected operating range information and the road change information.

[0050] Specifically, if the vehicle is not in the corrected operating range, it is determined that the activation condition is not met; if the vehicle is in the corrected operating range, the corrected distance is compared with the road type change length; when the corrected distance is greater than or equal to the road type change length, it is determined that the activation condition is met; when the corrected distance is less than the road type change length, it is determined that the exit condition is met.

[0051] In one embodiment, before comparing the corrected distance with the road type change length, it also includes: when the road change type is a change between any two road types among expressways, urban expressways, ramps between expressways and expressways, ramps between expressways and urban expressways, ramps between urban expressways and urban expressways, ramps between expressways and urban roads, and ramps between urban expressways and urban roads, if the vehicle is in the corrected operating range and the navigation driving assistance function has been activated, the vehicle continues to travel with the navigation driving assistance function.

[0052] It should be noted that when the road change type is a change between any two of the above road types, for example, when the current road type is an urban expressway and the road type ahead is a ramp between a highway and an urban expressway, and when the vehicle is within the correction operating range and the navigation driving assistance function has been activated, the correction distance and the length of the road type change do not need to be considered, that is, the navigation driving assistance function will not exit and the vehicle will continue to drive with the navigation driving assistance function. Of course, the road change type between any two of the above road types is also subject to certain restrictions, that is, there must be a natural connection between the two road types. For example, the two road types of highway and the ramp between the highway and the urban expressway have a natural connection, and the highway can have a connection relationship with the ramp; for example, the ramp between the highway and the urban expressway and the urban road has no natural connection, and the highway has no connection with the ramp.

[0053] See Figure 5 , Figure 5 FIG. 1 is a schematic diagram showing the operating range of the navigation driving assistance function according to an exemplary embodiment of the present application. Figure 5As shown, the road types in the figure include urban roads or other types, ramps between expressways or urban expressways and urban roads, and expressways or urban expressways. Urban roads are not included in the operating range involved. Of course, other road types that are not included in the operating range are also included. Ramps between expressways and urban roads, expressways, or urban expressways are variations between any two of the aforementioned road types. Therefore, if the vehicle's revised operating range includes the portion of the designed operating range enclosed by the dotted box in the figure, the vehicle's current position is within it, and the navigation driving assistance function has been activated, the two factors of the correction distance and the length of the road type change do not need to be considered. In this case, the navigation driving assistance function will not be exited, and driving with the navigation driving assistance function will continue.

[0054] Step S250: If the activation condition is met, the navigation driving assistance function is activated; if the navigation driving assistance function has been activated and the exit condition is met, the navigation driving assistance function is exited.

[0055] When the vehicle meets the activation conditions of the navigation driving assistance function, the navigation driving assistance function is controlled to be activated. When the navigation driving assistance function has been activated and the exit conditions of the navigation driving assistance function are met, the navigation driving assistance function is controlled to exit. Of course, if the navigation driving assistance function has not been activated and the activation conditions of the navigation driving assistance function are not met, the vehicle will not enter the navigation driving assistance mode.

[0056] In one embodiment, after exiting the navigation driving assistance function, it also includes: in response to the exit of the navigation driving assistance function, sending a display instruction to the human-computer interaction interface of the center console, and the display instruction carries an exit notification of the navigation driving assistance function to prompt the user that the navigation driving assistance function has been exited.

[0057] After the navigation driving assistance function is exited, the vehicle will respond to the exit of the navigation driving assistance function by sending a display instruction to the center console human-computer interaction interface, so that the center console human-computer interaction interface will display an exit notification to prompt the user that the navigation driving assistance function has been exited, so that the user can take over.

[0058] The navigation-assisted driving function control method provided in the above embodiment uses real-time environmental information collected by the vehicle to correct the initial operating range and the initial distance of the vehicle from the end point of the operating range in the initial operating range information of the navigation-assisted driving function determined based on the high-precision map to obtain the corrected operating range information. The obtained corrected operating range information can more accurately reflect the operating range of the navigation-assisted driving function. Then, based on the corrected operating range information and the road change information determined based on the high-precision map, the activation conditions or exit conditions of the navigation-assisted driving function are judged, thereby achieving precise control of the activation and exit of the navigation-assisted driving function, effectively solving the problems of incorrect activation of the navigation-assisted driving function, too short a usable range, frequent entry and exit, etc. due to possible errors or discontinuous fragments in the high-precision map, thereby improving the user's driving experience.

[0059] See Figure 6 , Figure 6 This is a block diagram of a navigation-assisted driving function control device shown in an exemplary embodiment of the present application. The device can be applied to Figure 1 It should be understood that the apparatus may also be applicable to other exemplary implementation environments and specifically executed by devices in other implementation environments, and this embodiment does not limit the implementation environment to which the method is applicable.

[0060] like Figure 6 As shown, this embodiment provides a navigation-assisted driving function control device 600, which includes:

[0061] Acquisition module 610, for acquiring the vehicle's current road information and road change information from the high-precision map, where the current road information includes the current vehicle position and the current road type, and the road change information includes the type of the road ahead, the type of road change, and the length of the road type change;
