Description

Technical Field

[0001] This application relates to the field of vehicle-mounted device technology, and in particular to a method, device, equipment and storage medium for providing navigation information. Background Technology

[0002] Navigation information refers to various operational guidance information generated by a vehicle navigation system based on the planned driving route. This information helps the driver perform driving maneuvers such as turning, changing lanes, and entering / exiting ramps. When the driver is on a call, their attention shifts from the road environment and navigation information to the conversation. In this situation, the driver may miss crucial navigation information, leading to missed key points, traffic violations, or even accidents.

[0003] In related technologies, navigation information is primarily provided through visual prompts displayed on the vehicle's navigation interface or through voice prompts played via the in-vehicle audio system. When the driver is on a call, methods such as lowering the volume of the voice prompts, delaying their playback, or even completely muting them are typically employed to avoid auditory interference between navigation voice and call voice, ensuring the continuity of the call.

[0004] However, when the driver is on a call, the driving load varies depending on the driving conditions and the mode of communication. As a result, the above methods suffer from a lack of diverse prompting strategies and low effectiveness in transmitting navigation information. Summary of the Invention

Detailed Implementation

[0026] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0027] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0028] Figure 1 This is a schematic diagram of an implementation scenario provided in an embodiment of this application. (Reference) Figure 1 The implementation scenarios provided in this application include an information acquisition unit 11, a control unit 12, and a navigation information prompting unit 13.

[0029] The information acquisition unit 11 is used, but is not limited to, acquiring the real-time driving speed, current road conditions, and current vehicle location of the vehicle during driving, as well as the driver's communication status during driving, such as the driver's communication method and duration. This application does not impose any restrictions in this regard.

[0030] For example, the information acquisition unit 11 may include an in-vehicle positioning module, a vehicle-to-everything (V2X) traffic interaction module, and a vehicle CAN (controller area network) bus data acquisition module. The information acquisition unit 11 acquires driving conditions by, for example, analyzing the vehicle's current location and speed using the BeiDou / GPS (global positioning system) positioning signal received by the in-vehicle positioning module, acquiring real-time road traffic status and road type information through the V2X traffic interaction module, and acquiring dynamic data related to vehicle driving through the vehicle CAN bus. Furthermore, the information acquisition unit 11 may also include an in-vehicle camera, an in-vehicle Bluetooth module, and a vehicle-to-everything (V2X) call detection module. The information acquisition unit 11 acquires call status by, for example, identifying the driver's handheld phone gestures using the in-vehicle camera to determine the call mode, or detecting the Bluetooth call connection status through the in-vehicle Bluetooth system, and identifying the in-vehicle hands-free call trigger signal through the vehicle-to-everything (V2X) call detection module. This application makes no limitations in this regard.

[0031] The navigation information prompting unit 13 is used, but is not limited to, outputting navigation-related prompts to provide targeted guidance to the driver. The navigation information consists of multiple navigation guidance event nodes arranged in spatial order along the vehicle's driving path. Each of these navigation guidance event nodes is a critical path node requiring the vehicle to perform operations such as turning, lane changing, and entering / exiting ramps while traveling along the planned path. Each navigation guidance event node is also associated with a location in geographic space and corresponding navigation guidance operation information. The spatial order of the navigation guidance event nodes indicates the order in which their corresponding locations are located within the driving sequence, specifically based on their distance from the vehicle's current location. The closer the distance, the higher the navigation guidance event node's ranking in the navigation path queue, indicating that the vehicle will soon perform driving operations according to the navigation guidance information within that node to successfully pass its corresponding location. Conversely, the farther the distance, the lower the ranking of the navigation guidance event node in the navigation path queue, indicating that it will be a subsequent navigation guidance operation for the vehicle.

[0032] For example, the navigation information prompting unit 13 may include an in-vehicle audio system for playing, but not limited to, voice prompts in the prompting information, such as controlling the corresponding side of the in-vehicle audio system to output voice prompts according to the steering type of any navigation guidance event node; or, the navigation information prompting unit 13 may also include an in-vehicle display terminal for playing, but not limited to, visual prompts in the prompting information, such as displaying turn arrows, distance countdowns, lane-level guidance diagrams, etc., on the central control screen, instrument panel, or head-up display; or, the navigation information prompting unit 13 may also include an in-vehicle haptic feedback module for playing, but not limited to, haptic prompts in the prompting information, such as controlling the corresponding side of the steering wheel or the corresponding area of ​​the seat to vibrate according to the event type of the key node, or causing the gear lever to vibrate at a fixed point.

[0033] The control unit 12 is used, but is not limited to, to control the navigation information prompting unit based on the driving conditions and call status obtained by the information acquisition unit 11. For example, it adjusts the volume of the voice prompts, the contrast, brightness, and flashing frequency of the visual prompts, and the vibration frequency of the tactile information based on the driving conditions and call status obtained by the information acquisition unit.

[0034] Optionally, the control unit may be, for example, an on-board controller, a control unit, or any other type of on-board terminal or cloud server capable of performing control functions; this application makes no restrictions in this regard.

[0035] Those skilled in the art should understand that the above-described information acquisition unit 11, control unit 12, and navigation information prompting unit 13 are merely examples. Other existing or future information acquisition units, control units, and navigation information prompting units that are applicable to this application should also be included within the scope of protection of this application, and are hereby incorporated by reference.

[0036] Figure 2 This is a flowchart of a navigation information prompting method provided in an embodiment of this application. This method can, for example, be... Figure 1 The control unit shown performs the actions, and this application makes no limitations in this regard. See also Figure 2 The navigation information prompting method provided in this application embodiment may include steps S210-S250.

[0037] Step S210: Obtain the vehicle's driving conditions and navigation information. The navigation information consists of multiple navigation guidance event nodes arranged in spatial order along the vehicle's driving path.

[0038] For example, vehicle driving conditions are used to indicate the overall environment and vehicle status during vehicle operation, including but not limited to the vehicle's real-time speed, current road conditions, number of lanes, and road type. Navigation information consists of a series of ordered navigation guidance operation requirements that the vehicle must follow to travel along the planned route. It includes multiple navigation guidance event nodes arranged in spatial driving order. Each of these navigation guidance event nodes represents a location in geospatial space and associated navigation guidance operation information matching that location. The navigation guidance information corresponding to any navigation guidance event node is used to indicate the driving operation procedures and route guidance requirements for guiding the vehicle to successfully pass through the corresponding location.

[0039] In some embodiments, the planned driving route is, for example, a route determined by the navigation system installed in the vehicle based on the location of the destination and the location of the departure point for this trip. The location of the destination is, for example, input by the driver through interactive methods provided by the vehicle, such as manual input via the vehicle's touchscreen, voice command, selection via an in-vehicle navigation app, or synchronization via smartphone mirroring. The location of the departure point is, for example, determined by the current real-time location collected by an in-vehicle positioning module such as BeiDou / GPS installed in the vehicle; this application does not impose any limitations on this.

[0040] Step S220: When the driver of the vehicle is in a call state, determine the driver's load level based on the driving conditions and the call mode. The load level indicates the degree of attention the driver is paying while in a call state.

[0041] For example, the call status is used to indicate the state of the driver interacting with an external communication object through a communication terminal while the vehicle is in motion. The call status includes, but is not limited to, information such as call method, call duration, and call connection status. The call method indicates how the call status is implemented, such as, but not limited to, handheld calling, calling via in-vehicle Bluetooth, or the hands-free function of the communication terminal; the communication terminal is, for example, a mobile phone, a smartwatch, or a dedicated in-vehicle communication terminal, etc., and this application does not impose any limitations in this regard.

[0042] The driver's workload level indicates the degree of attention the driver is engaged during a call. It reflects, but is not limited to, the amount of cognitive resources the driver can allocate to road observation, vehicle control, and navigation information reception after considering the call status and the vehicle's driving conditions. For example, a higher driver workload level indicates fewer cognitive resources available for these tasks, while a lower workload level indicates more.

[0043] In some embodiments, the driver's workload level is a graded quantitative indicator based on driving conditions and communication methods in common driver call scenarios. For example, it includes low workload level, medium workload level, and high workload level. In the low workload level, the communication method is, for example, the driver making calls via in-vehicle Bluetooth or the hands-free function of the communication terminal. The driving conditions are, for example, the vehicle speed is less than a first speed threshold, and the vehicle is on rural roads, open roads, or other first-class driving conditions that do not require frequent acceleration or deceleration and have no complex intersections. In this case, the driver can operate the steering wheel with both hands, only hearing is occupied, and the driver can allocate more cognitive resources to road observation, vehicle control, and navigation information reception, meaning the driver's attention is less occupied.

[0044] Under medium load level, the communication method is not limited, that is, the communication method is, for example, through the vehicle's Bluetooth or hands-free communication terminal, or the driver's handheld communication terminal. The driving conditions are, for example, the vehicle speed is greater than the first speed threshold but less than the second speed threshold, and / or the road conditions where the vehicle is located are the second driving conditions that require frequent acceleration and deceleration, such as traffic lights and intersections. At this time, due to one or more interference factors such as high vehicle speed, complex road conditions, and one-handed driving, the cognitive resources that the driver can allocate to road observation, vehicle control and navigation information reception are reduced compared to low load level, that is, the degree of attention required by the driver is higher.

[0045] In the high-load level, the communication method is, for example, the driver uses a handheld communication terminal, and the driving conditions are, for example, the vehicle speed is greater than the second speed threshold, and the vehicle is in the third driving condition, such as a high-speed wind tunnel or a complex urban intersection, which requires lane changing and turning. At this time, due to the further increase in vehicle speed, the driver's judgment window for driving operations is shorter, and there are one or more interfering factors such as high speed, complex road conditions, and one-handed driving. The cognitive resources that the driver can allocate to road observation, vehicle control, and navigation information reception are reduced compared to the medium-load level, and the degree of attention occupancy of the driver is the highest.

[0046] Step S230: Determine the first key node among multiple navigation guidance event nodes.

[0047] Step S240: If the first critical node meets the first specified condition, determine the first prompt information of the first critical node according to the load level.

[0048] For example, the method for determining the first critical node is as follows: among a plurality of navigation guidance event nodes arranged in spatial order, the navigation guidance event node in the first position is determined as the first critical node. The first-position navigation guidance event node is, for example, the navigation guidance event node whose corresponding second position is closest to the vehicle's first position. In this case, the vehicle is about to perform driving operations according to the navigation guidance information in the first critical node, requiring the driver to obtain navigation information in a timely manner to successfully pass the second position corresponding to the first critical node.

[0049] Alternatively, the method for determining the first critical node could be as follows: based on the driver's driving habits, the highest priority node among multiple navigation guidance event nodes is identified as the first critical node. High-priority nodes are, for example, nodes where the driver is prone to illegal driving operations, easily misses them, or hesitates in operation, potentially leading to driving risks. The priority of multiple navigation event nodes can be adjusted according to the actual scenario, and this application does not impose any restrictions in this regard.

[0050] Optionally, driving habits may be automatically generated by the vehicle's control unit based on historical data related to the driver's driving operations; or they may be obtained by actively questioning the driver. This application does not impose any restrictions in this regard.

[0051] In some embodiments, the first specified condition is, for example, that the distance between the vehicle's first position and the second position corresponding to the first key node is less than a first distance threshold. When the distance between the second position corresponding to the first key node and the vehicle's current first position is less than the first distance threshold, it indicates that there is key information in the navigation information that requires the driver to pay attention to it in a timely manner and prepare to perform the corresponding driving operation. That is, the driver needs to allocate cognitive resources to obtain navigation information and perform driving operations. Therefore, the first prompt information of the first key node can be determined based on the driver's current workload level to achieve accurate triggering and personalized adaptation of navigation prompts, ensuring that the driver can effectively receive and respond to key navigation commands under the current cognitive workload. The value of the first distance threshold can be adjusted according to the actual application scenario, and this application does not impose any restrictions in this regard.

[0052] In this scenario, the method for determining the first prompt information for the first critical node based on the load level includes, for example: if the load level does not reach the first level threshold, weakening the first voice prompt information in the second prompt information and enhancing the first visual prompt information in the second prompt information to obtain the first prompt information; if the load level reaches the first level threshold, weakening the first voice prompt information, enhancing the first visual prompt information, and adding tactile prompt information to obtain the first prompt information. The second prompt information is used to provide a prompt for the first critical node when the driver is not in a call state.

[0053] As mentioned above, the driver's load level is, for example, a categorized quantitative indicator that classifies the driver's driving conditions and communication methods under common communication scenarios, including low load level, medium load level, and high load level. Based on this, the first level threshold is, for example, the high load level.

[0054] In this situation, a method to weaken the first voice prompt, enhance the first visual prompt, and add tactile prompts can be employed. This includes, for example, weakening the volume of the first voice prompt in the second prompt, enhancing the brightness and flashing frequency of the first visual prompt in the second prompt, and simultaneously adding tactile information by vibrating the steering wheel, seat, etc. This reduces the driver's auditory load when the driver is on a call and under high cognitive load. Furthermore, multi-channel fusion prompts compensate for the limitations of single visual prompts, and the strong perceptual characteristics of touch are used to deliver key navigation instructions to the driver under high cognitive load, ensuring the driver can quickly identify and respond to upcoming driving operations, effectively reducing driving safety risks.

[0055] Optionally, when the load levels include low load, medium load, and high load, and the first load threshold is high load, if the load level does not reach the first load threshold, the method for weakening the first voice prompt in the second prompt information and strengthening the first visual prompt in the second prompt information to obtain the first prompt information includes, for example, weakening the first voice prompt in the second prompt information once and strengthening the first visual prompt in the second prompt information once if the load level is low load and the load level is medium load if the load level is medium load and the first voice prompt in the second prompt information is weakened a second time and the first visual prompt in the second prompt information is strengthened a second time to obtain the first prompt information.

[0056] A method for weakening the first voice prompt in the second prompt and enhancing the first visual prompt in the second prompt may include, for example, weakening the volume and number of syllables of the first voice prompt in the second prompt, i.e., lowering the volume and reducing the number of syllables, and enhancing the brightness and flashing frequency of the first visual prompt in the second prompt. This is to reduce the auditory interference of navigation voice on the call while ensuring the effective transmission of key navigation information by enhancing visual prompts when the driver is on a call and the load level has not reached a high load level, thus balancing call continuity and navigation prompt effectiveness.

[0057] In the above method, by pre-calibrating low, medium, and high load levels and setting the high load level as the first level threshold, the method provided in this application embodiment can realize a step-by-step, refined, and dynamic adaptation of the navigation prompt strategy according to the actual cognitive load level of the driver during the call. It matches the appropriate voice attenuation and visualization enhancement for low and medium load levels, which not only avoids the problem that a single prompt adjustment strategy cannot adapt to different load scenarios, but also ensures the effectiveness of the transmission of key navigation information under different load conditions by reducing the interference of navigation voice on the call and through gradient visualization enhancement, accurately balancing the call continuity and the prompt needs of driving navigation, and improving the adaptability and practicality of the navigation prompt strategy.

[0058] Step S250: Play the first prompt message according to the type of the first key node to provide a prompt for the first key node.

[0059] For example, the type of the first key node is used to indicate the navigation guidance operation type and road driving scenario characteristics corresponding to the node. For example, it indicates a scenario where the second position corresponding to the first key node requires going straight through a non-forking intersection, a scenario where a turning is required at a forking intersection, or a scenario where an entry or exit ramp is required, etc. This application does not impose any restrictions in this regard.

[0060] In some embodiments, the first prompt information includes, for example, a second voice prompt information; the type of the first key node includes, for example, a first type for indicating vehicle steering; the vehicle is equipped with, for example, multiple audio playback channels, which are installed in different positions; the method of playing the first prompt information according to the type of the first key node includes, for example,: if the type of the first key node is the first type, determining a target audio playback channel among the multiple audio playback channels according to the steering direction indicated by the first type; and playing the second voice prompt information through the target audio playback channel. For example, if the first key node is a first type indicating that the vehicle is turning left at a second position corresponding to the first key node, then the audio playback channel corresponding to the left turn among the multiple audio playback channels is determined as the target audio playback channel.

[0061] Optionally, the first prompt information may include, for example, a second tactile prompt information, such as vibration of the steering wheel, seat, etc. Playing the first prompt information according to the type of the first key node may also include determining the vibration position of the second tactile prompt information according to the type of the first key node.

[0062] In some possible scenarios, the navigation information prompting method provided in this application embodiment may further include: prompting the first key node through a second prompt message when the driver exits the call state and does not re-enter the call state within a first specified time period. The value of the first specified time period can be adjusted according to the actual application scenario. After the driver exits the call state, the first specified time period provides a reasonable buffer window for adjusting the navigation prompt strategy, avoiding frequent or erroneous adjustments to the prompt message. This helps ensure the stability and smoothness of navigation prompt mode switching, while also preventing operational interference to the driver caused by repeated switching of the prompt strategy due to brief call interruptions, thus improving the overall user experience of navigation prompts.

[0063] Considering that in practical applications, if driving conditions are complex and the driver's workload is too high, simply playing prompts may not guarantee effective reception of navigation information, potentially leading to driving safety hazards. Therefore, the navigation information prompting method provided in this application embodiment further includes, for example, generating third prompt information when the driving conditions meet a second specified condition and the workload level reaches a third workload level threshold. This third prompt information prompts the driver to interrupt the call and provides a reminder of the first key node, enabling the driver to concentrate on performing navigation guidance operations, effectively avoiding the driving risks caused by high-load call activity combined with complex driving conditions, and ensuring vehicle driving safety.

[0064] The second specified condition includes, but is not limited to, complex road scenarios such as vehicles traveling on highway ramps, continuous curves, intersections, or construction sections, or operating conditions requiring high driver concentration such as high real-time vehicle speed, sudden reduction in the number of road lanes, or the presence of sudden road condition warnings. The third load level threshold may be the same as or different from the first load level threshold; this application makes no restrictions in this regard.

[0065] In other embodiments, the first key node includes key navigation guidance information that guides the vehicle through the second location corresponding to the first key node. The navigation information prompting method provided in this application embodiment further includes, for example,: after playing the first prompting information according to the type of the first key node, if the vehicle does not pass through the second location according to the key navigation guidance information within a second specified time period, updating the navigation information; generating a fourth prompting information based on the updated navigation information, the fourth prompting information being used to prompt the driver to interrupt the call and prompt the second key node in the updated navigation information; playing the fourth prompting information so that the driver can pay attention to the route deviation in a timely manner and concentrate on performing the corrected navigation operation, avoiding the continuous deviation of the route due to the distraction of attention during the call, while ensuring the timeliness and accuracy of the navigation prompts, and further improving the reliability of navigation guidance during driving.

[0066] The technical solution provided in this application, on the one hand, can monitor the driver's workload level in real time based on the vehicle's driving conditions and the call mode when the driver is on a call. This helps to accurately characterize the driver's attention level during the call, providing a quantitative basis for the dynamic adaptation of navigation information prompts. On the other hand, the method provided in this application also determines the first prompt information of the first key node based on the driver's real-time workload level when a first key node that meets the first specified condition appears among multiple navigation guidance event nodes. This achieves accurate matching between navigation information prompts and the driver's current workload level, improving the effectiveness and relevance of navigation information transmission and helping to avoid navigation information reception failures caused by insufficient or excessive prompts. In addition, since different types of navigation guidance event nodes correspond to different driving operation requirements, this application embodiment can also determine the output method of the first prompt information according to the type of the first key node, ensuring that the driver can quickly identify and respond to key navigation commands even under high workload levels, effectively reducing driving safety risks.
