For other terminal devices, the method of collecting data including address information is the same as that of the mobile phone side, and only the mobile phone is used as an example for introduction in this embodiment of the application. After other terminal equipment collects the data containing the address information, it can send the data containing the address information to the mobile phone. It should be understood that other terminal devices may uniformly send feedback messages to the mobile phone at fixed time intervals, the feedback message may contain data containing address information, or may send data containing address information to the mobile phone in a certain order, etc. This application is not limited to this. Of course, if the terminal device does not collect data containing address information within a fixed time interval, the feedback message does not include data containing address information at this time.

Exemplarily, taking the terminal equipment in the application scenario shown in FIG. Data containing address information is sent to the mobile phone 11 every 5 minutes. Or, when which terminal device collects the data containing address information first, it will first send the data containing address information to the mobile phone. For example, the tablet computer 12 collects the data containing address information at 7:30 in the morning, and the notebook computer 13 collects the data containing address information. When the data containing address information is collected at 7:35 in the morning, the tablet computer 12 first sends the data containing address information to the mobile phone 11, and the notebook computer 13 then sends the data containing address information to the mobile phone.

As shown in FIG. 4A , it is a schematic flowchart of a method for determining a destination provided in the embodiment of the present application. As shown in FIG. 4A , mobile phones and other terminal devices (for example, can be recorded as "8+N" devices, such as watches, speakers, etc.) can collect data. Specifically, mobile phones can collect data from multiple dimensions such as voice assistants, chat messages, input methods, clipboards, and applications, such as browsers, text messages, and calendars, and then obtain data containing address information in different dimensions, such as voice , chat history text, input method text, clipboard text, browser search terms, SMS parsing address, map navigation address, friend sharing address, etc. The following is an example of a specific scenario to introduce data containing address information collected in different dimensions.

1. Chat history

(1) User A tells user B via WeChat chat: "I'm going to the company" 5 minutes before getting on the bus.

(2) User A shared the address link with user B 10 minutes before getting on the bus, for example: No. 93, Xuegang Road, Longgang District, Building 1, Tianan Yungu.

2. Browser

User A searches the browser for "How to get to Tian'an Yungu?" 30 minutes before getting on the bus.

3. Map

User A searches for and navigates to "Building 1, Tian'an Yungu" on the map 20 minutes before boarding the bus.

4. SMS

User A sends a short message to user B or receives a short message from user B before getting on the bus. The content of the short message can be: No. 93, Xuegang Road, Longgang District, Building 1, Tianan Yungu.

5. Voice

User A said to the speaker 5 minutes before getting in the car: I am going to work; or said to the voice assistant "Xiaoyi Xiaoyi, navigate to Tianan Yungu".

It should be noted that the above-mentioned data source containing address information is only an example. In this application, data containing address information can also be obtained from other applications, such as a calendar, (for example: the user adds a Schedule information: Go to Sakata Hospital on August 21 to get the laboratory test form), etc., no specific restrictions on this. It should be understood that in the above application scenarios, for example, the content searched or sent by the user in the chat history, browser, and text message may be the content entered by the user through the input method, or the content pasted by the user from the clipboard, etc. No limit. Moreover, in the solution of this application, only soft sensing data is collected, which has the ability to cross operating systems and hardware devices, and has strong versatility.

Based on the above scenarios containing address information, the mobile phone can collect text data and voice data containing address information. At the same time, the mobile phone can collect the occurrence time of text data and voice data, such as the address link shared by user A to user B at 7:20 in the morning, and user A searched and navigated a certain address through AutoNavi Maps at 7:10 in the morning information etc. Exemplarily, after the mobile phone collects the data containing the address information, it may store the event corresponding to the data containing the address information and the time of occurrence of the event, for example, in the table shown in Table 1 below. Certainly, the mobile phone may also save the collected data including the address information according to the occurrence time of the event, which is not limited in this application.

Table 1

time	event
7:00 am	browser search
7:10 am	map search address
7:20 am	Share address link with friends
7:25 am	Say to the speakers: I'm off to work

It should be understood that the time information in the above table and the events that occurred at the corresponding time are only illustrative descriptions, which are not limited in the present application.

S302: The mobile phone determines a candidate address according to the acquired data.

For the convenience of description, the address corresponding to the data including the address information collected in S301 may be recorded as a candidate address, and there may be at least one candidate address.

In some embodiments of the present application, the mobile phone can parse the data containing address information to obtain the address information included therein. Taking FIG. 4A as an example, for example, for speech, the speech may be converted into text first, and then steps such as word segmentation, keyword extraction, semantic understanding, address recognition and other steps are performed on the text to obtain address information. For example, for the voice "I'm going to work", the keyword: go to work can be obtained, and then after semantic understanding, it can be obtained: go to the company to work, so the candidate address in the voice "I'm going to work" is: company. Another example, for text, such as the text searched in the browser: "How to go to Tianan Yungu", the mobile phone can segment the text, keyword extraction, semantic understanding, and address recognition to get the "How to go to Tianan Yungu" The candidate address is: Tianan Yungu.

S303: The mobile phone determines the destination address according to the candidate address.

Continuing to take Figure 4A as an example, after the mobile phone obtains the candidate address, it can modify the candidate address based on the user's frequent driving address, event occurrence time information, distance, visit times, etc., to obtain the destination address. The process of how to obtain the destination address will be described in detail below.

As a possible implementation, after the mobile phone performs address recognition on at least one piece of data containing address information to obtain at least one candidate address, the confidence level of the at least one candidate address may be determined based on the address frequently visited by the user. Among them, the user's frequent driving address can be the address manually entered and saved by the user on the car or mobile phone, or the GPS location information of the user's frequent driving address obtained according to the GPS location information of the vehicle and the time information of the user's getting on and off the car, and then Get the user's frequent driving address, or it can also be learned by the mobile phone within a preset period of time (for example, 1 month) based on the address entered by the user, or it can also be obtained by the mobile phone based on the data on the car (for example, the user is in the car Afterwards, the address information is input on the car, the mobile phone establishes a connection with the car, and the mobile phone can obtain the data on the car) and so on, which are not limited in this application.

Exemplarily, it is assumed that the candidate addresses include: (1) Tian'an Cloud Valley; (2) the company; (3) three addresses of Block A of Tian'an Cloud Valley. Assume that the user’s frequent driving addresses include two: (1) parking lot No. 101, Building A, Building 1, Tian’an Yungu; (2) B2 underground parking lot, Building 2, Shenzhen Bay No. 1. The mobile phone can match the above three candidate addresses with the two frequent addresses respectively to obtain the first confidence level of each candidate address. For example, the first confidence level of Tianan Cloud Valley is 0.8, and the company's first confidence degree is 0.6, and the first confidence degree of Block A of Tianan Yungu is 0.9. It should be noted that in practical applications, names such as "company" and "home" in candidate addresses need to be replaced with corresponding address information for calculation.

In this application, the address information is obtained by combining voice, text, search words, navigation addresses, and friends’ shared address links and other soft-sensing data, and the matching degree is calculated with the user’s historical address, which can avoid misidentifying addresses and improve the accuracy of address identification Rate.

It should be understood that "Parking Space No. 101, Building A, Building 1, Tian'an Yungu" in the above example may be the company's address, and "Shenzhen Bay No. 1, Building 2, B2 Underground Parking Lot" may be the location of the home. Not limited.

Further, after the mobile phone obtains the first confidence degree of the candidate address according to the user's frequent driving address, it can obtain the second confidence degree of the candidate address according to the time length between the current time (that is, the time when the user boards the car) and the event occurrence time. Wherein, the second confidence degree is a confidence degree calculated based on the first confidence degree combined with time.

As a possible implementation, the second confidence degree can be calculated through the time decay function, that is, the longer the event occurrence time is from the current time, the lower the confidence coefficient is, and the closer the event occurrence time is to the current time, the higher the confidence coefficient . For example, the events collected before the user gets on the bus include: Event 1: User A tells user B through WeChat chat at 7:30 in the morning 5 minutes before getting on the car: "I'm going to the company now"; Event 2: User A is in the The address link shared with user B at 7:20 in the morning; event 3: User A searched and navigated a certain address information through Gaode map at 7:35 in the morning. Among the above three events, the confidence coefficient of the address information included in event 2 is smaller than the confidence coefficient of the address information included in event 1, and the confidence coefficient of the address information included in event 1 is smaller than that of the address information included in event 3 confidence coefficient.

Exemplarily, the second confidence degree can be calculated by the following formula:

s _i ＝exp(-k*t _i )·m _i , k is a constant

Among them, t _i represents time, m _i represents the first confidence degree, and s _i represents the second confidence degree.

In the above formula, the confidence coefficient C _i =exp(-k*t _i ), that is, s _i =C _i ·m _i . Since the confidence coefficient is related to the time difference (the difference between the user's boarding time and the event occurrence time), in the embodiment of the present application, the confidence coefficient can be set according to the time difference. Exemplarily, when the time difference<10 minutes, the confidence coefficient C _i can take a value of 1; when 10 minutes<time difference<=30 minutes, the confidence coefficient C _i can take a value of 0.8; When the difference is >30 minutes, the confidence coefficient C _i can take a value of 0.5. It should be understood that the value of the above confidence coefficient is only an example, and the present application does not specifically limit it.

Since multiple identical addresses may appear in candidate addresses, the third confidence degree of the address can be obtained by summing the confidence degrees of the same address at this time, for example, it can be calculated by the following formula:

ω＝∑s _i

Wherein, s _i represents the second confidence degree, and ω represents the numerical value of the third confidence degree obtained by summing the confidence degrees of the same address.

It should be understood that the third confidence level may be the same as or different from the second confidence level. When a candidate address appears only once, the third confidence level is the same as the second confidence level; when the same candidate address appears multiple times, the third confidence level is different from the second confidence level.

The third confidence level of the candidate address can be calculated through the above formula. For example, the third confidence level of Tianan Cloud Valley is 0.7, the third confidence level of the company is 0.85, and the third confidence level of Block A of Tianan Cloud Valley is 0.95.

Further, after obtaining the third confidence degree of the candidate address, the mobile phone may weight the third confidence degree based on the distance information, the number of visits, etc., that is, continue to modify the candidate address to obtain the destination address. In some embodiments, the mobile phone can query the detailed address list corresponding to the destination address through the map application, and then correct the candidate address based on the distance between the user's frequented address and the address in the list. Exemplarily, taking Block A of Tianan Yungu among the candidate addresses as an example, the mobile phone can query Block A of Tianan Yungu on the map, and then find the detailed address list corresponding to Block A of Tianan Yungu. Frequently visited parking addresses, such as the distance between "Parking Space No. 101, Parking Lot No. 101, Building A, Building 1, Tian'an Yungu" and each address in the list.

As a possible implementation, in this embodiment of the application, a distance threshold (for example, 200 meters) can be set, and some addresses can be filtered through the distance threshold, for example, addresses with the same name and far from the addresses frequently visited by the user can be filtered out, for example Search for "Tianan Yungu Block A" and you will find: Tianan Yungu in Guangming District, Tianan Yungu in Longgang District, etc. When the distance between the address frequently visited by the user and the addresses in the list is greater than 200 meters, the address may be filtered out. Assuming that the frequent driving address is "Parking Space No. 101, Block A, Building 1, Tian'an Yungu (Longgang District)" and "Tianan Yungu, Longgang District", the nearest is "Tianan Yungu Building A", then correct "Tianan Yungu Building A" to "Tianan Yungu Parking Space No. 101, Block A, Building 1". That is, in the solution of the present application, a more precise address can be obtained, such as a parking space, so that the destination information is more accurate.

As another possible implementation manner, after some addresses are filtered out by the distance threshold, the addresses may be further filtered based on the number of visits. For example, if there are two addresses within the range of the distance threshold, one address needs to be selected from the two addresses, and the candidate address is corrected to this address, which can be compared according to the number of visits. Exemplarily, assuming that addresses satisfying the threshold range include D1 and D2, if the number of times the user has visited D1 within a month is higher than the number of visits to D2, the confidence coefficient of D1 can be set higher than that of D2. In this way, the candidate address can be corrected to the address with the highest confidence, for example, the candidate address can be corrected to the address of D1.

Through the above method, the corrected address of the candidate address with the highest confidence can be obtained, and the corrected address of the candidate address with the highest confidence can be used as the destination address.

S304: The mobile phone sends the destination address to the vehicle.

In some embodiments, before the user gets on the car, the mobile phone can obtain the destination of the user, and then when the user gets on the car, the destination address can be directly sent to the car machine, so that the user does not need to manually input the destination, which can Reduce user operations and improve user experience.

Specifically, the trigger conditions for the mobile phone to send the destination address to the vehicle may include the following situations:

The first situation: After the user gets on the car, the camera on the car can collect the user's face image, and then perform face recognition authentication. After the authentication is passed, the mobile phone can establish a connection with the car, and the mobile phone can transmit data with the car. For example, the mobile phone can send the determined destination address to the car.

Case 2: When the user gets in the car, the user can log in the account on the car device, which is the same as the account logged in on the mobile phone, for example, it can be the same Huawei account. When the account on the car machine is successfully logged in, the mobile phone can establish a connection with the car machine. At this time, the mobile phone can send the determined destination address to the car machine.

The third case: the mobile phone and the car are connected through the near-end communication technology, for example, the mobile phone and the car are connected through Bluetooth. During or after the connection is established, data can be synchronized between the mobile phone and the vehicle. For example, the mobile phone can send destination data to the vehicle.

Of course, the above trigger conditions are only a schematic illustration. In practical applications, other trigger conditions can also be used. For example, the mobile phone and the car can also synchronize data periodically (for example, synchronize data every 1 minute). Applications are not limited to this.

S305: The car machine outputs prompt information.

In some embodiments, the prompt information may be in the form of a card, for example, a navigation card may be displayed on the vehicle. As shown in FIG. 4B , it is a schematic diagram of a display interface of a car machine provided by the embodiment of the present application. After the user gets on the car, an interface 400 can be displayed on the car machine, and a navigation card 401 can be included in the interface 400. Of course, the interface 400 may also include icons of application programs, such as icons of a map application program and application icons of a Xiaoyi suggestion application program. Wherein, the destination name 4011 can be displayed on the navigation card 401, such as "navigate to the company", and time prompt information 4012, such as "driving to the company now, it is expected to take 20 minutes longer than usual". After the user clicks the navigation card 401 , the car machine can respond to the user's click operation, open the map application program, and display multiple navigation routes to the company, such as the display interface 410 . The user can select a route among the multiple routes shown in the interface 410, and then click the "Start Navigation" button 411, and the car machine can respond to the user's click operation on the "Start Navigation" button to start the navigation function.

In some other embodiments, after the user clicks the navigation card 401, the car machine can directly enter the navigation interface in response to the user's click operation. That is, there is no need for the user to select a route, the vehicle can select a route according to preset rules, and then navigate according to the selected route. For example, the preset rule may be the route with the shortest driving time, or the route that the user often drives, etc., which is not limited in this application.

It should be noted that Xiaoyi suggests that it can dynamically recommend services for users based on their usage habits. It can display users' frequently used applications, and can also display cards, services and other content based on users' habits.

It should be understood that if the company's address is saved on the car and the address is "Parking Space No. 101, Building A, Building 1, Tian'an Yungu", then when the destination address is the company's address, "navigate to the company" can be displayed; If the address of the company is not saved on the vehicle, the display interface of the vehicle may display "Navigate to parking space No. 101, parking lot, Block A, Building 1, Tian'an Yungu", which is not limited in this application. It should be noted that the addresses of "home", "company" and other locations can be set by the user on the vehicle, or learned by the vehicle itself, and of course can also be set by the user on the mobile phone or other terminal devices. There is no limitation on the synchronization to the car machine by the mobile phone or other terminal equipment.

As a possible implementation, the vehicle can calculate the navigation time from the current location to the destination. If the navigation time is abnormal (for example, the time is 20% longer than the usual time), it will display the time prompt information, such as the display in the figure The displayed prompt message 4012 is: "It is expected to take 20 minutes longer than usual to drive to the company now". Of course, the above time prompt information is only a schematic description, for example, it may also display "It is expected to take 50 minutes" or "It is expected to arrive at 9:20", etc., which is not limited. It should be noted that, in practical applications, more or less content than that shown in the figure may be displayed on the display interface of the vehicle, which is not limited in this application. Exemplarily, if the time required for the user to depart from the current location to the destination is within a certain range from the time required for normal driving, for example, within 5 minutes, the time prompt information 4012 may not be displayed.

In some other embodiments, the prompt information may be voice prompt information, for example, it may be: Please confirm whether you want to navigate to the company? At this point, the user can interact with the voice assistant on the car, such as replying "navigate to the company" or replying "yes". Then, the voice assistant on the car machine can receive the user's reply information, and then the car machine can call the map application to display multiple routes to the company for navigation, and then the user selects a route for navigation.

For example, assume that the user says to the voice assistant on the mobile phone 5 minutes before boarding the car: Xiaoyi Xiaoyi, navigate to Bantian Primary School. Since the user is relatively close to the boarding time, it is considered that the user's intention to go to Bantian Primary School is relatively high. Strong, that is, the user has the highest possibility of navigating to Bantian Elementary School, then when the user gets on the car, the car can output voice prompt information, such as "Do you want to navigate to Bantian Elementary School?". Or, if the user shared the address link with friends 10 minutes before getting on the bus, it can also be considered that the user is more likely to go to the shared address, then when the user gets on the car, he can give a voice prompt message, such as "Do you want to navigate?" Go to xxx amusement park?".

In some other embodiments, after getting on the car, the user can click on the

The application program and the car machine can respond to the user's click operation to open the interface of the Gaode map application program. At this time, if the user clicks on the address search interface, the address search interface can display a list of destination addresses, for example, the interface shown in Figure 4C. Wherein, the destination address list is a list of all/partial addresses in which the candidate addresses are sorted according to the second confidence level, and the first address is the candidate address with the highest second confidence level. For example, in the destination address list on the interface shown in Figure 4C, "Tian'an Yungu (company)" is at the first, "Bantian Primary School" is at the second, and "Shenzhen Bay No. 1 (home)" is at the third.

In some other embodiments, the car machine can learn the driving route of the user according to the location information input by the user on the mobile phone or the location information input by the user in the map application program of the car machine. For example, when the user goes to work in the company every day, he will send his children to school first, such as driving to "Sakata Elementary School" first, and then continue to drive from "Sakata Elementary School" to the company. When the user gets on the car, if the user clicks

application, then

The address search interface of the application can display a list of destination addresses according to the user's habits. For example, the first address is Bantian Primary School, and the second address is Tian'an Yungu (Company). Go to Bantian Elementary School, then switch the destination to the company after arriving at Bantian Elementary School, and then navigate from Bantian Elementary School to the company.

In some other embodiments, the destination address can be obtained in combination with multiple dimensions. For example, user A added schedule information on August 21 in the calendar: go to Sakata Hospital to get the test sheet, and the reminder time is: 10:00-10:00 in the morning 10. Then at 9:55 a.m. on August 21, he sent a message to user B via WeChat chat: I was going to pick up the laboratory test form, but the company needed me to deal with something temporarily, so I might not be able to pick it up today. The mobile phone side understands the semantics of the message sent by user A, and concludes that the user cannot go to the hospital temporarily, but needs to go to the company, that is, the destination is the company. In this way, when the user gets on the car, a prompt message can be displayed on the car, such as "navigate to the company", or the voice assistant sends a reminder "do you want to go to the company". Of course, the voice assistant can also send out a reminder "to go to the company or the hospital", and then the user can respond to the voice assistant's message and interact with the voice assistant.

It should be understood that FIG. 4C and FIG. 4D are only schematic illustrations, and the destination address list may display more or fewer addresses when an actual product is realized.

The above method is described below by taking a specific scenario as an example.

Scenario 1: Map Navigation

Referring to Figure 5A, assuming that the user opens the AutoNavi map 5 minutes before getting in the car to check the road conditions for driving to the company (for example, check whether there is a traffic jam), the mobile phone can collect this data, and think that the user has a strong intention to go to this address , then the address can be used as the destination of the user's current trip. When the user gets on the car, the car machine can output prompt information. For example, the car machine can display the interface 500 in FIG. 5A, which can include the prompt information 501 output by the voice assistant. Navigate to the company? At this point, the user can interact with the voice assistant to confirm the destination to be navigated to.

Scenario 2: Friends share addresses

As shown in Figure 5B, assume that user A chats with a friend through WeChat 10 minutes before getting on the bus, and the friend shares an address link with user A, for example, the address is Shenzhen Bay Park. After the mobile phone collects the data, it can be considered that the user has a strong intention to go to the address, and the address is recorded as the destination address. When the user gets on the car, prompt information may be displayed on the car, for example, the interface 510 shown in FIG. 5B may be displayed. Among them, the interface 510 may include a navigation card 511, and the navigation card 511 may include prompt information, such as "navigate to Shenzhen Bay Park" 512, and then the user clicks on the navigation card 511, and the vehicle can automatically select a route to navigate to Shenzhen Bay Park.

Through the above-mentioned embodiment, the destination of the user can be inferred before the user gets on the car, and then after the user gets on the car, the car machine can output the destination prompt information, that is, the user does not need to manually input the destination information, which reduces the user operation , can improve user experience.

Based on the above embodiments, the present application also provides a flow chart of a destination navigation method, as shown in Figure 6, the method may include the following steps:

S601: The mobile phone collects data including address information.

S602: The mobile phone determines a candidate address according to the collected data.

S603: The mobile phone sends the candidate address to the vehicle.

It should be noted that the mobile phone can obtain data containing address information from other terminal devices, and then the mobile phone will organize the data uniformly to obtain candidate addresses, and finally the mobile phone will send the candidate addresses to the vehicle. Alternatively, the mobile phone and other terminal devices may also send data including address information to the vehicle, which is not limited in this application.

S604: The vehicle and the machine correct the candidate address to obtain the destination address.

S605: The car machine outputs prompt information.
