Description

Vehicle navigation control method and device and vehicle

Technical Field

The present invention relates to the field of vehicle navigation systems. And more particularly, to a control method, apparatus and vehicle for controlling navigation muting by acquiring a selected geographical location.

Background

In the existing navigation system, a user only needs to input a destination, a navigation display does not need to be checked in the driving process, and the navigation system can perform real-time voice broadcasting on a driving route in the traveling process. Audio navigation is an essential function for almost all navigation systems in view of the fact that users can receive route guidance without having to observe a navigation display, thereby improving the convenience and safety of users driving along a planned route.

Vehicle navigation systems are commonly integrated within the audiovisual infrastructure of a vehicle, providing navigation services through the display and speakers of the vehicle infotainment system. This also causes a user to be confused by voice navigation from time to time when using the in-vehicle entertainment system or receiving a voice call. Voice navigation is no longer necessary when the user is traveling on a familiar route or a simple road segment, such as a very familiar route around a daily commute route, residence, workplace, school, or the like, or a simple route such as a highway, or even when the user has traveled several times in the past and no longer needs voice prompts. And continuous high-decibel voice navigation prompt may cause user annoyance, distract and increase driving fatigue. Typically in such a scenario, the user would choose to mute the voice navigation, or turn off the navigation directly.

The conventional navigation system resumes voice broadcast only after the user cancels the mute after being muted by the user, which may cause the user to miss a destination when the user does not concentrate on the driving route, or miss an important exit or intersection on a road section such as an expressway of a simple route. And further increases the risk of the user driving if he/she is going to look at the route on the display while the navigation is silent. And obviously, the behavior of directly turning off the navigation is more unfavorable for the full use of the navigation.

In the prior art, according to the number of times that a user traverses a route, a scheme for automatically making a navigation decision to stop voice navigation on road sections which traverse more frequently is adopted, but the scheme has more problems that the travel needs to be recorded according to different users so as to distinguish familiar routes determined for different users, and whether the same user needs to automatically mute when driving the route which was familiar before a long time again after a long time interval, and the like, and the user needs to perform complicated operations and the like. Further, the degree of familiarity of the user with the route depends not only on the number of traversals, but also on the memory and concentration of the user, the time interval of the traversals, and the like, and even if the user is familiar with the route, some important intersections may be missed due to the attention and the like, and the automatic mute navigation causes great trouble to the user and is not convenient for the navigation system to provide services for the user.

Therefore, how to provide a technical scheme for stopping voice navigation when a user does not need voice guidance and automatically recovering the voice navigation in time when the user wants to give a voice prompt is a problem to be solved in the prior navigation technology.

< method examples >

The vehicle navigation control method of the embodiment realizes that the user can preset the path using the voice guidance prompt according to the self requirement, stops broadcasting in the path where the user does not need to use the voice navigation, and resumes the voice broadcasting in the path where the user wants to obtain the voice navigation again, and does not need to operate when the user resumes the voice navigation. The voice guidance prompt method has the advantages that the trouble of a user or the interruption of the use of video entertainment of the user caused by the continuous voice navigation prompt of the familiar route or the simple route is avoided, the voice guidance prompt can be timely recovered according to the location information selected by the user in advance, the user is reminded of the location of an exit or an intersection of an important road section to be reached, and the user is prevented from missing when the user is distracted. Meanwhile, the operation convenience of the user is improved through various setting modes such as voice input and touch input, the operation is simple, the flexibility of navigation voice broadcasting and mute setting is improved, and the use experience of the user is enriched.

FIG. 2 is a flow diagram of a vehicle navigation control method according to one embodiment. The control method of the present embodiment will be described below by taking a vehicle 1000 in fig. 1 as an example.

As shown in fig. 2, the control method of the present embodiment includes the following steps:

in step S210, a planned navigation route is provided;

the user may make a route planning request via, for example, an onboard navigation device on a vehicle that provides a planned navigation route. The navigation route generally includes data such as the total length of the navigation route, the time required for the navigation route, the coordinates of the start point and the end point of the navigation route, the coordinates of the passing points of the route, all coordinate points in the navigation route, and the route sections on the navigation route. The navigation data based on the planned navigation route further comprises navigation action information, such as the name of the next navigation action, the distance from the next navigation action, etc.; road information such as a current road name, a next road name, and the like; destination information such as remaining distance from the destination, remaining time from the destination, etc.; navigation states, such as start of navigation, yaw recalculation, congestion recalculation, etc.; the monitoring camera information includes, for example, latitude and longitude of the monitoring camera, distance from the monitoring camera, type and speed limit of the camera, etc.

Meanwhile, map data is also prestored in the vehicle navigation device. The map data mainly includes road network data, such as expressway, national road, provincial road, county road, country street and urban road; background data, e.g., parks, greenbelts, river seas, and railways, etc.; name data, such as road names, point of interest names, building names, etc.

In step S220, a mute setting start instruction is received;

in step S230, a selected geographic location is obtained;

the interface for receiving the command for starting the mute setting and acquiring the selected geographical location may be a unified interface or two associated interfaces. The geographic location may be a geographic coordinate location or a road segment, or may be a location of an associated building.

In one such embodiment, as shown in FIG. 3, the interface implementation for receiving the initiate mute setting instruction and obtaining the selected geographic location may be a voice input. For example, a voice instruction model may be preset, where the model may be an instruction keyword, such as "mute navigation", "mute", "exit navigation voice", or the like, or may be an instruction keyword plus a parameter, such as "mute" plus location information, or may be an instruction keyword, an object, and a parameter, such as "mute", "car navigation", and location information. The preset voice instruction model is not limited, and the required functions can be realized. Model parameters such as instruction keywords and the like are prestored in the voice instruction model. At the moment, the user only needs to speak a mute command and a place, for example, the user receives the voice input of place information such as 'mute' and 'east-straight subway station'. After receiving, recognizing a starting mute setting keyword and location information in voice input according to a preset voice instruction model, and after recognizing the location information, matching the location information with pre-stored map data to determine the geographical position selected by a user. The method can reduce the complexity of manual operation of a user by a voice input mode, is convenient for the user to input when the user is inconvenient to manually operate, is simple to operate, and enhances the flexibility of navigation use.

When the voice-recognized geographic information corresponds to a plurality of target locations, matching the location information with pre-stored map data to determine the selected geographic location further comprises: providing a prompt for the one or more matching results; receiving a selection of the one or more matching results to determine the selected geographic location. The method and the device provide a plurality of matched target location results for the user to select the expected location, give more options to the user, can better determine the location where the user wants to hear the voice navigation prompt, and have the advantage of providing accurate service for the user.

As shown in fig. 3, further, the interface implementation for receiving the command to start the mute setting and obtaining the selected geographic location may be a touch input in addition to a voice input. In one embodiment, the interface implementation for receiving the mute setting start instruction and acquiring the selected geographic location may be a touch input. For example, the navigation display screen provides a mute button and a planned navigation route and map. Receiving a selection of a mute button of a display screen; and receiving clicking on the map displayed by the display screen, and acquiring the geographic position of the touch point on the map as the selected geographic position. The operation convenience of the user is improved by multiple input modes of touch input and voice input, the flexibility of navigation use is improved, and the use experience of the user is enriched. Besides, the input mode can be a plurality of combination modes combining the voice and the touch, such as a physical button, a knob and the like.

In step S240, the selected geographic location is mapped to a geographic location on the planned navigation route according to a predetermined policy;

the preset strategy is a strategy of corresponding the selected geographic position to a geographic position on the planned navigation route, and aims to determine a position on the navigation route which is most in line with the requirement of a user as a reference position for recovering the voice prompt according to the geographic position selected by the user on the basis of not changing the planned navigation route.

In one embodiment, as shown in FIG. 3, where the selected geographic location can correspond to a plurality of locations on the planned navigation route, the predetermined policy comprises: and corresponding the selected geographic position to the geographic position coordinate with the shortest straight-line distance to the selected geographic position on the planned navigation route. And further determining the specific position on the planned navigation route which is actually expected to be selected by the user by selecting the geographical position with the shortest straight-line distance on the navigation route. The method of the embodiment can accurately acquire the position where the user wants to recover the voice navigation prompt, and the position has uniqueness.

In another embodiment, as shown in fig. 4, the predetermined policy includes: step S310, determining a relevant area on a map by taking the selected geographic position as a center; the determination of the association area may be, for example, a circle having a certain distance as a radius and centered on the selected geographic location, or an arbitrary shape determined based on an arbitrary distance and centered on the selected geographic location. Step S320, determining road segments within the associated region range in the road segments forming the planned navigation route; there may be one or more of the segments of the planned navigation route within the associated area. Step S330, calculating the distance between the selected geographic position and the geographic position coordinate of the marked key point of each road section in the associated region range; the distance between the selected geographic position and the geographic position coordinate of the key point in the road segment is calculated here, for example, the distance may be calculated by the geographic coordinate of the selected position and the geographic position coordinate of the key point in the road segment, and the calculation method is various and is not limited here. Step S340, as shown in fig. 3, corresponds the selected geographic position to the geographic position coordinate of the marked key point of the road segment with the shortest distance. The geographical position selected by the user is corresponding to the geographical position coordinates of the marked key points of the road section in the planned navigation route, so that the voice navigation prompt user is timely recovered based on the geographical position of the key points, the user is reminded of arriving at important intersections or exits and other places, and missing is avoided.

Further, in an embodiment, as shown in fig. 5, steps S241 to S243 correspond to steps S210 to S230 in fig. 2, and steps S246 to S248 correspond to steps S250 to S270 in fig. 2, which are described in detail in the embodiment corresponding to fig. 2, and therefore will not be described again here. In particular, as shown in fig. 5, the predetermined policy includes: step S244, determining whether the selected geographic location matches a certain road segment that constitutes the planned navigation route; step S245, if yes, the selected geographic location is corresponding to the geographic location coordinate of the marked key point of the road segment. By the method, the selected geographical position as the road section can be directly searched and matched in the road section of the planned navigation route, the complex step of distance calculation is omitted, and the geographical position where the user wants to recover the voice navigation prompt can be quickly corresponded.

In one embodiment, the key points marked in the above steps include: one or a combination of a start point, an end point, or a routing key point of the road segment. The planned navigation route includes information of each planned road section, each road section has a starting point and an end point, and the planned navigation route may also have important passing key points, for example, the passing key points may be a certain intersection or a traffic light. The key point used to correspond to the selected geographic location may be a start point, an end point, or a route key point of the road segment, or may be a combination of a start point, an end point, or a route key point of the road segment. Therefore, the voice prompt can be recovered when the user reaches the starting point of the road section where the voice navigation prompt is expected to be recovered, and the user can pay higher attention to the road section in time.

In step S250, according to the start-mute setting instruction, keeping the voice navigation prompt mute in the navigation process of the planned navigation route; by the steps, the situations that the user is annoyed or interrupted to use audio-video entertainment, answer a call and the like caused by continuous voice navigation prompt in the process of driving on a familiar route or a simple route are avoided.

Step S260, judging whether the navigation object reaches the vicinity of the geographic position on the corresponding planned navigation route on the planned navigation route;

in step S270, the voice navigation prompt is restored.
