Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a flowchart of a navigation information processing method according to a first embodiment of the present invention. As shown in fig. 1, the navigation information processing method includes:
in step S101, the in-vehicle device receives a navigation request message including a destination input by a user.
Specifically, in the process of navigating by using the vehicle-mounted device, a user needs to input a destination name needed to arrive in a navigation system provided by the vehicle-mounted device, and the vehicle-mounted device searches the navigation system and a navigation map according to the destination name needed to arrive input by the user to determine the destination of the current navigation. The user input mode can be self-input by the user, clicking on a navigation map, selecting from a menu provided by the vehicle-mounted device, and the like.
Step S102, the vehicle-mounted device determines whether the destination input by the user exists in the frequent destination record, wherein the frequent destination record comprises the position information corresponding to the frequent destination of the user, which is automatically recorded by the vehicle-mounted device in the past driving process.
Specifically, the navigation system provided by the vehicle-mounted device stores a frequent destination record, the frequent destination record stores information such as position information and name of destination information which is once arrived by a user in the past driving process and is selected and recorded by the user according to the prompt of the vehicle-mounted device, and the vehicle-mounted device judges whether the frequent destination record contains the position information corresponding to the destination input by the user.
In step S103, if the destination exists, navigation processing is performed based on the position information corresponding to the destination.
Specifically, if the frequent destination record contains the position information corresponding to the destination which is input by the user and needs to be reached, the vehicle-mounted equipment establishes a navigation route from the current position to the destination on a navigation map according to the position information corresponding to the destination in the frequent destination record, and then guides the user to drive the vehicle to the destination according to the established navigation route by using the GPS.
In the embodiment, the vehicle-mounted device automatically records the destination information in the past driving process, so that when a user needs to arrive at the destination again, the vehicle-mounted device can automatically establish a navigation line to the destination by inputting the name of the destination, the purpose of accurate navigation is realized, and the problem that in the prior art, when the destination which the user needs to arrive at is not identified in the vehicle-mounted device, accurate navigation cannot be performed is solved.
Fig. 2 is a flowchart of a navigation information processing method according to a second embodiment of the present invention. As shown in fig. 2, the navigation information processing method includes:
in step S201, the in-vehicle device receives a navigation request message containing a destination input by a user.
In step S202, the vehicle-mounted device determines whether there is a destination input by the user in the frequent destination record, where the frequent destination record includes location information corresponding to the user frequent destination automatically recorded by the vehicle-mounted device in the past driving process. If yes, go to step S203, and if not, go to step S204.
In step S203, if the destination exists, navigation processing is performed based on the position information corresponding to the destination.
In step S204, if the destination does not exist, after the user arrives at the destination, the current position information of the destination is recorded in the past driving record.
Specifically, if it is determined in step S202 that there is no location information corresponding to the destination that needs to be reached and is input by the user in the frequent destination record, the user performs the navigation operation by using a general method for performing the navigation operation by using the existing in-vehicle device. Firstly, inputting a place name which is relatively known near a destination to be reached in a navigation system or selecting a rough position near the destination to be reached on a navigation map, then establishing a navigation route from the current position to the selected place by vehicle-mounted equipment, guiding a user to drive a vehicle to move to the vicinity of the destination to be reached, and then finding the destination to be reached by the user. After the user arrives at the destination and stops the vehicle, the vehicle-mounted device records the current position information of the destination in the past driving record. The past driving record is used for recording the position information of the destination which the user has arrived at and the number of times of arriving at the destination.
The position information of the destination to be reached recorded in the past driving record may be:
first, after the user arrives at the destination, current location information of the arrival destination is acquired.
Specifically, after a user drives a vehicle to reach a destination, the vehicle-mounted device determines that the user has reached the destination according to a certain parking trigger signal, and the vehicle-mounted device acquires the position information of the current location through the GPS module. The parking trigger signal may be an operation of stopping the vehicle such as turning off the vehicle or engaging a shift position to a parking position by a user.
Then, the current position information and the position information of the destination recorded in the past driving record are weighted and averaged, the position information of the destination recorded in the past driving record is updated by adopting the position information after weighted and averaged, and the arrival times of the destination are recorded.
Specifically, if the distance between the current position information acquired by the vehicle-mounted device after the user parks the vehicle and the position information of a destination recorded in the past driving record is smaller than a preset value, the current position of the user is considered to be the same as the destination recorded in the past driving record, the coordinate value of the current position and the coordinate value of the destination recorded in the past driving record are weighted and averaged, the obtained coordinate value is a new coordinate value of the destination, and the position information of the destination in the past driving record is updated to the new coordinate value. And records the number of times the destination is reached, each time the destination is reached, the number of times is incremented by one. The weighted average calculation method comprises the following steps: the number of times that a destination has arrived in a past record is used as a weight of a coordinate value of the destination that has arrived in a past record, the weight of the coordinate value of the current position is set as 1, the coordinate value in the past record is multiplied by the sum of the weight and the coordinate value of the current position, the sum of the two weight values is divided, the calculated coordinate value is used as a new coordinate value of the destination, and the position information of the destination in the past record is updated.
The preset value of the distance difference between the current position and the position in the past driving record may be preset by a user, or may be automatically preset by the vehicle-mounted system, for example, the distance in the vehicle-mounted system is automatically preset to 100 meters, and if the vehicle-mounted device determines that the distance between the current position and the position of a destination recorded in the past driving record is less than 100 meters, the current position and the destination recorded in the past driving record are considered to be the same place.
The distance between the current position and the destination in the past driving record may be calculated according to longitude and latitude coordinate values of the current position and the destination in the past driving record, for example, the following formula may be used for calculation:
distance R2 × arcsin (sin)2((lat1-lat2)/2)+cos(lat1)×cos(lat2)×sin2((lng1-lng2)/2))
Where R is the average radius of the earth (assuming that the earth is a standard sphere), and the latitude and longitude GPS coordinates of the current position and the destination in the past driving record are (lat1, ng1), (lat2, ng2), respectively.
According to the method for recording the current position information of the destination in the past driving record, the vehicle-mounted equipment is triggered to automatically record the position information of the parking place through the parking of the user, the position information of the place is updated through weighted average calculation, the position information of the destination which the user currently arrives at is recorded more accurately, and accurate navigation can be achieved when the user needs to arrive at the destination again.
Further, before the user arrives at the destination, the vehicle-mounted device may record the position information during driving at intervals of a preset time. The preset time interval is preset in the vehicle-mounted device in advance (for example, 1 second), and the current position information is recorded every other time interval during the driving process. And after the user arrives at the destination, the position information recorded last time is taken as the current position information. Specifically, after the vehicle-mounted device detects the parking trigger information, a situation that the parking place has no GPS signal may occur, so that the vehicle-mounted device cannot acquire the position information of the parking place, and at this time, the vehicle-mounted device uses the last recorded position information before reaching the destination as the position information of the current parking place.
The method is used for when the destination to which the user needs to arrive is a place without a GPS signal, such as a basement, a high-rise building and the like, at the moment, if the user needs to record the position information of the place, the position information recorded when the GPS signal exists at the last time is taken as the position information of the place, the position is usually an entrance of the destination to which the user needs to arrive, and the vehicle-mounted equipment can accurately guide the user to travel to the place again by recording the position information at the entrance of the place.
In step S205, it is determined whether the number of times the destination has arrived exceeds a preset threshold.
Specifically, after the user stops the vehicle each time and triggers the vehicle-mounted device to record the current destination position information in the past driving record and update the position information, the number of times of arriving at the destination is recorded at the same time. The vehicle-mounted equipment can preset a threshold value of the arrival times in a mode set by a user or automatically set by a system, and each time the vehicle-mounted equipment updates the current destination position information in the past driving record, whether the arrival times of the destination exceed the preset threshold value is detected. If the vehicle navigation information exceeds the preset value, executing the step S206, and if the vehicle navigation information does not exceed the preset value, finishing the vehicle navigation process.
In step S206, if the destination arrival times exceeds the preset threshold, the user is prompted whether to add the name and the location information of the destination to the first prompt information in the frequent destination record.
Specifically, the vehicle-mounted device is preset with first prompt information for prompting a user whether to add the name and the position information of the destination to the frequent destination, when the user drives the vehicle to reach the destination, the vehicle-mounted device judges that the arrival times of the destination exceeds a preset threshold value, the first prompt information is prompted to the user for the user to select, if the user selects to add the name and the position information of the destination to the record of the frequent destination, the step S207 is executed, otherwise, the step S209 is executed. The method for prompting the user to select the first prompt information by the vehicle-mounted equipment can be provided for the user to select through a pop-up menu of a touch display screen of the vehicle-mounted equipment.
Step S207, receiving the name of the destination input by the user; or searching the place name within the preset distance range from the destination on the navigation map, providing a menu for the user to select, and taking the place name selected by the user as the name of the destination.
Specifically, the user selects the first prompt information, and the in-vehicle device may prompt the user to input the name of the destination currently reached. A user can perform manual input through a touch display screen provided by the vehicle-mounted equipment; or the user can search the place name within the preset distance range from the current destination from the navigation map according to the preset distance range on the vehicle-mounted equipment and select and input the place name on the provided menu. For example, the vehicle-mounted device may preset a distance range value, arrange the location names on the navigation map within the preset range from near to far according to the distance from the current destination, and generate a menu for the user to select, and if there is no location name that the user needs to use in the menu, the user may manually input the location name through a touch screen of the vehicle-mounted device. Specifically, for example, the destination where the user arrives is a certain office building of the work place of the user, and the preset distance range in the vehicle-mounted device is 200 meters, the vehicle-mounted device arranges the names of all the places on the navigation map within 200 meters near the current destination from near to far, a menu is generated for the user to select, and the user can find the name of the office building in the menu for selection and input; if the name of the office building is not in the menu generated by the vehicle-mounted device, the user can manually input the name of the office building through the touch screen of the vehicle-mounted device. The vehicle-mounted device takes the name of the place input by the user as the name of the destination.
In step S208, the name and location information of the destination reached is added to the frequent destination record.
Specifically, the in-vehicle apparatus matches the name of the destination input by the user and the location information of the destination, and adds the destination information to the frequent destination record. After the operation is completed, the navigation process of the vehicle-mounted equipment is completed.
Step S209 is to prompt the user whether or not to add the location information of the destination to the second prompt information in the record of the destination.
Specifically, the vehicle-mounted device is also provided with second prompt information for prompting the user whether to add the position information of the destination to the destination. In step S206, if the user confirms that the name and the location information of the destination are not to be added to the frequent destination record according to the first prompt information, further prompting a second prompt information to the user for the user to select, and if the user selects to add the location information of the destination to the frequent destination record, performing step S210, otherwise, the navigation process of the vehicle-mounted device is completed. The method for prompting the user to select the second prompt message by the vehicle-mounted device can be provided for the user to select through a pop-up menu of a touch display screen of the vehicle-mounted device.
In step S210, the location information of the destination to be reached is added to the destination record.
Specifically, in step S209, if the user confirms to add the location information of the destination to the emergency destination record according to the second prompt message, the vehicle-mounted device may add the location information of the destination currently reached to the emergency destination record. The emergency destination record is stored in the vehicle-mounted device, and when the user arrives at the destination with the destination arrival frequency exceeding the preset threshold value, the vehicle-mounted device does not prompt the first prompt message and the second prompt message to the user again. The vehicle-mounted device can also provide an option, and when certain destination information is deleted from the record of the destination, the user arrives at the destination, and the arrival times of the destination exceed the preset threshold, the vehicle-mounted device can send out the first prompt information and the second prompt information again. After the operation is completed, the navigation process of the vehicle-mounted equipment is completed.
According to the method for prompting the user to select the second prompt information by the vehicle-mounted equipment, the destination which does not need navigation guidance or destination information which is not interested by the user can be shielded, and the efficiency of the user in navigation operation is improved.
In the embodiment, whether the destination to be reached is added into the frequent destination record is judged by detecting the number of times that the user reaches the destination, so that the user can directly select from the frequent destination record when the user needs to reach the destination again, and the vehicle-mounted equipment can automatically establish a navigation line and achieve the purpose of accurate navigation.
FIG. 3 is a flowchart of a navigation information processing method according to a third embodiment of the present invention. The embodiment of the method may be performed after the first embodiment of the method, and as shown in fig. 3, the navigation information processing method includes:
in step S301, the in-vehicle device receives a navigation request message including a destination input by a user.
Step S302, the vehicle-mounted device determines whether the destination input by the user exists in the frequent destination record, wherein the frequent destination record comprises the position information corresponding to the frequent destination of the user, which is automatically recorded by the vehicle-mounted device in the past driving process.
In step S303, if the destination exists, navigation processing is performed based on the position information corresponding to the destination.
Step S304, sending out the message to the user.
Specifically, when the user drives the vehicle to travel to the destination selected in the frequent destination record in accordance with guidance of the in-vehicle device, the user may be issued a message to the user. In addition, after the user drives the vehicle to travel to the destination selected in the frequent destination record according to the guidance of the vehicle-mounted device and performs parking triggering, the vehicle-mounted device can send out the message to the user. The vocalizing information can be preset in the vehicle-mounted equipment by a user or automatically set by the vehicle-mounted equipment.
Further, the issuing of the uttering information to the user includes: one or more of voice message information, image message information, character message information and animation message information. The voice message information, the image message information, the character message information and the animation message information can be preset in the vehicle-mounted equipment by a user or automatically matched and set by the vehicle-mounted equipment; the combination of the utterances can also be preset in the vehicle-mounted equipment by the user or automatically matched and set by the vehicle-mounted equipment. The voice message information and the character message information can be automatically generated by the vehicle-mounted equipment according to the frequent destination name input by the user, and the image message information and the animation message information can be automatically matched according to the semantics of the frequent destination name input by the user. For example, when the user has driven a car many times to reach the place of the home and joins the home as a destination to a usual destination named "home" under the prompt of the in-vehicle device, the in-vehicle device may issue voice greeting information of "welcome home" when the user reaches the destination corresponding to the name "home" and display a short animation film representing the family on the display screen while displaying a word of "welcome home" on the display screen when the destination name input by the user on the in-vehicle device is "home" and the combination of issuing greeting information is automatically set by the in-vehicle device by default.
According to the embodiment, the user sends out the message information to the user after arriving at the destination, the diversity of the navigation function of the vehicle-mounted equipment is enriched, and the experience of the user is improved.
