Example two
The embodiment provides a vehicle-mounted navigation method, which is applied to a navigation device, and as shown in fig. 2, the method comprises steps S201, S202, S203, S204, S205 and S206, which will be described in detail below.
In step S201, the navigation device receives a keyword, where the keyword is obtained by identifying voice data collected by the voice device by the cloud voice identification server.
The voice device may be a microphone disposed in the car, and the voice device receives the user's spoken words, for example, the user speaks "go a shop", the voice data collected by the voice device is "go a shop",
the voice device sends the collected voice data to the cloud recognition server through the Ethernet,
the cloud identification server identifies the received voice data, extracts keywords in the voice data, for example, the keyword of going to market A is market A,
specifically, the method for the cloud recognition server to recognize the voice data may adopt an algorithm based on Dynamic Time Warping (DTW), a Hidden Markov Model (HMM) method based on a parametric Model, or a Vector Quantization (VQ) method based on a non-parametric Model,
the cloud recognition server extracts the keywords, sends the keywords to the navigation equipment through the Ethernet,
optionally, the cloud recognition server further recognizes the received voice data, extracts voiceprint information therein, judges the identity of the user according to the voiceprint information, extracts a corresponding identity, stores a corresponding database of voiceprints and the identity in the cloud recognition server, and can enable the user to add and store the voiceprints and the identity by using the voice device and the navigation device, and the cloud recognition server also sends the identity to the navigation device through the ethernet.
In step S202, points of interest are determined from the keywords.
The navigation equipment matches with the interest points stored in the navigation equipment according to the received keywords, takes the interest points with similarity larger than a first threshold value as the interest points to be selected, plays the audio of the interest points to be selected, or displays the interest points to be selected on a screen, and determines the interest points according to the selection operation of the user when the selection operation in the form of voice or touch of the user is received so as to determine the interest points which the user wants to go forward from the interest points to be selected.
In the step S202, the interest point desired by the user is determined from the interest points to be selected, and the following method may also be adopted:
according to the identity identification information sent by the cloud identification server, the historical selection record of the user corresponding to the identity identification is obtained, and according to the historical selection record, the interest point with the largest user selection frequency is directly determined from the interest points to be selected and used as the interest point which the user wants to go forward.
In step S203, a corresponding route and route guidance information corresponding to the route are generated according to the point of interest.
Specifically, the navigation device generates route navigation information for each key position on the route, and configures a route navigation information trigger position for each route navigation information according to the corresponding key position, the route navigation information trigger position is a position where the route navigation information starts to be played under the condition that the corresponding route navigation information can be played right before the vehicle reaches the key position when the route navigation information trigger position is driven to the key position at the preset highest speed, when the vehicle runs along the planned route, the key position and the navigation information trigger position corresponding to the same piece of navigation information always reach the navigation information trigger position first and then reach the key position, thereby playing the role of informing the user in advance, so that the user is prepared in advance and controls the vehicle, the running time between the route navigation information trigger position and the key position is enough for the driver to control the vehicle according to the route navigation information, for example, a key position on the route is an intersection, and the navigation information of the key position is used for reminding the user to turn right at the intersection, the trigger position corresponding to the navigation information is 50 meters away from the intersection and close to the direction in which the vehicle drives, so that when the vehicle drives to the trigger position of the navigation information, the navigation information is broadcasted, and the user is reminded in advance.
In step S204, the route is sent to the cloud query server.
The navigation device may send the route to the cloud query server using ethernet,
optionally, the navigation device further sends the identity to a cloud query server using ethernet.
In step S205, route expansion information obtained by the cloud query server according to the route query is received and stored.
Receiving and storing route expansion information of a predetermined type obtained by the cloud query server according to the route query, wherein the predetermined type is determined according to history selection records or voice data,
specifically, the cloud query server obtains a historical selection record corresponding to the identity according to the identity sent by the navigation device, and determines a preset type of route extension information according to the historical selection record, for example, a certain user prefers to obtain food and drink information along the way, and in the historical selection record, the selection times of the extension information of the selected food and drink type are the most, so that after the identity of the user is obtained, the preset type of the extension information needing to be generated is determined to be the food and drink type according to the historical selection record, and the cloud query server obtains the route extension information of the food and drink type according to the route query.
As an alternative embodiment, the route extension information includes voice route extension information, for example, when the route extension information is a restaurant-type route extension information, the voice route extension information may be a voice introducing the location and the dish characteristics of each restaurant; the system also comprises a corresponding route expansion information triggering position and priority, the priority can be determined by means of real-time selection of a user or pre-storage of the system, and the route expansion information with high priority is played preferentially. Different types of route extension information have different priorities, for example, the system can default that the priority of the route extension information of the traffic condition type is higher than that of the route extension information of the catering information; for example, when the route extension information is a restaurant type route extension information, the priority may be set according to the score of each restaurant or the selection history of the user, and the priority is higher for restaurants that have been selected by the user and higher for restaurants that have been selected by the user. In step S206, route guidance information and route extension information are played according to the current arrival position of the vehicle.
Specifically, the route extension information includes the voice route extension information, a corresponding route extension information trigger position, and a priority, and step S206 specifically includes:
calculating a distance difference value between the current arrival position of the vehicle and the next route navigation information triggering position;
calculating a first predicted time for reaching the next route navigation information triggering position according to the current speed and distance difference value of the vehicle;
alternatively, the following method may be used to calculate the first estimated time:
calculating a first predicted time for reaching the next route navigation information triggering position according to the average speed and the distance difference value of the vehicle;
acquiring all route expansion information to be played at a route expansion information triggering position between a current arrival position of a vehicle and a next route navigation information triggering position;
judging whether the sum of the playing time of all the route extension information to be played is less than a first predicted time, namely judging whether all the route extension information to be played can be completely played before the vehicle reaches the next route navigation information triggering position;
if the judgment result is yes, namely all the route expansion information to be played cannot be played completely before the vehicle reaches the next route navigation information triggering position, all the route expansion information to be played is played in the order of high priority to low priority, so that a user can preferentially obtain more meaningful route expansion information within limited time and distance, for example, when the route expansion information of a catering type and the route expansion information of a traffic condition type exist at the same time, the route expansion information of the traffic condition type with high priority is preferentially broadcast; when catering type route extension information is broadcasted, if the fact that the route extension information to be broadcasted cannot be broadcasted completely is judged, a restaurant with a high score and selected by a user is broadcasted preferentially. .
If the judgment result is negative, directly playing all the route extension information to be played,
specifically, if the judgment result is negative, it is judged that all the route extension information to be played can be completely played before the vehicle reaches the next route navigation information triggering position, and in this case, all the route extension information to be played is played, so that the user can obtain richer and more comprehensive extension information.
When the navigation route information and the route extension information are played by using the method of the step S206, since the first predicted time is estimated according to the current vehicle speed and the distance difference, the vehicle speed generally does not keep the current vehicle speed unchanged, when the vehicle speed becomes fast, the actual time for the vehicle to reach the next navigation route information trigger position is shorter than the first predicted time, and the vehicle reaches the next navigation route information trigger position in advance, there is a possibility that the navigation route information should be played and the route extension information is not played completely, at this time, the following method is used to ensure that the user can obtain the navigation route information in time:
when the vehicle currently arrives at the route navigation information triggering position and detects that the route extension information is being played, the playing of the route extension information is paused, the route navigation information is played,
and after the route navigation information is played, the playing of the route extension information is resumed, so that the user can acquire the route navigation information in time and adjust the vehicle in time to drive along the planned route.
According to the vehicle navigation method provided by the embodiment, the keywords are received, and the keywords are obtained by identifying the voice data acquired by the voice equipment through the cloud voice identification server; determining interest points according to the keywords; generating a corresponding route and route navigation information corresponding to the route according to the interest points; sending the route to a cloud query server; receiving and storing route expansion information obtained by the cloud query server according to the route query; according to the current arrival position of the vehicle, the route navigation information and the route extension information are played, so that the user can obtain more abundant and multivariate extension information while obtaining necessary navigation information in the driving process.

the distance calculation submodule 3061 is used for calculating a distance difference between the current arrival position of the vehicle and the next route navigation information triggering position;
the time calculation submodule 3062 is used for calculating a first predicted time for reaching the next route navigation information triggering position according to the current speed and the distance difference value of the vehicle;
alternatively, the time calculation submodule 3062 may calculate the first estimated time by:
calculating a first predicted time for reaching the next route navigation information triggering position according to the average speed and the distance difference value of the vehicle;
the obtaining submodule 3063 is configured to obtain all route expansion information to be played between the current arrival position of the vehicle and the next route navigation information triggering position of the route expansion information triggering position;
the judging submodule 3064 is configured to judge whether the sum of the playing times of all the route expansion information to be played is smaller than the first expected time, that is, judge whether all the route expansion information to be played can be completely played before the vehicle reaches the next route navigation information triggering position;
the sequential playing sub-module 3065 is configured to, if the determination result is yes, that is, if it is determined that all the route extension information to be played cannot be completely played before the vehicle reaches the next route navigation information trigger position, play all the route extension information to be played in the order of the higher priority to the lower priority, so that the user can preferentially obtain more meaningful route extension information within a limited time and distance, for example, when route extension information of a catering type and route extension information of a traffic condition type exist at the same time, preferentially broadcast route extension information of a traffic condition type with a higher priority; when catering type route extension information is broadcasted, if the fact that the route extension information to be broadcasted cannot be broadcasted completely is judged, a restaurant with a high score and selected by a user is broadcasted preferentially. The playing module 306 further includes: the direct playing module sub-module 3066, is used for directly playing all the route expansion information to be played if the judgment result is negative,
specifically, if the judgment result is negative, it is judged that all the route extension information to be played can be completely played before the vehicle reaches the next route navigation information triggering position, and in this case, all the route extension information to be played is played, so that the user can obtain richer and more comprehensive extension information.
When the playing module 306 is used to play the navigation route information and the route extension information, since the first predicted time is estimated according to the current vehicle speed and the distance difference, the vehicle speed generally does not keep the current vehicle speed unchanged, when the vehicle speed becomes fast, the actual time for the vehicle to reach the next navigation route information trigger position is shorter than the first predicted time, and the vehicle may reach the next navigation route information trigger position in advance, which may cause that the route extension information is not played completely, and in order to avoid this problem, the playing module 306 further includes:
a pause submodule 3067 for pausing the playing of the route extension information, playing the route navigation information,
the resume play sub-module 3068 is configured to resume playing the route extension information after the route navigation information is played, so as to ensure that the user can obtain the route navigation information in time, and adjust the vehicle in time to drive along the planned route.
