Abstract

A method for exchanging information between in-vehicle terminals, and an in-vehicle terminal is provided. The method includes a first in-vehicle terminal that triggers, by sending a broadcast message, at least one surrounding second in-vehicle terminal to establish a first relationship with the first in-vehicle terminal, and establishes a second relationship with at least one third in-vehicle terminal. The first in-vehicle terminal separately exchanges information about a correspondence type with the at least one second or third in-vehicle terminal so that more vehicles can intelligently exchange in-vehicle information, and exchange different information with different in-vehicle terminals. This can properly protect privacy information.

Claims

automatically sending, by a first in-vehicle terminal, a broadcast message, wherein the broadcast message comprises an identifier of the first in-vehicle terminal;

establishing, by the first in-vehicle terminal, a first relationship with at least one second in-vehicle terminal that receives the broadcast message;

selecting, by the first in-vehicle terminal, a third in-vehicle terminal from the at least one second in-vehicle terminal to establish a second relationship based on a rule generated by the first in-vehicle terminal;

establishing, by the first in-vehicle terminal, the second relationship with the third in-vehicle terminal from the at least one second in-vehicle terminal in response to selecting the third in-vehicle terminal from the at least one second in-vehicle terminal based on the rule generated by the first in-vehicle terminal;

separately exchanging, by the first in-vehicle terminal, first information corresponding to the at least one second in-vehicle terminal and second information corresponding to the third in-vehicle terminal with each of the at least one second in-vehicle terminal and the third in-vehicle terminal, respectively, wherein the first information comprises non-privacy information, and wherein the second information comprises privacy information and non-privacy information;

recording, by the first in-vehicle terminal in a relational database according to at least one of the identifier of the at least one second in-vehicle terminal and an identifier of the third in-vehicle terminal, a quantity of times of establishing the first relationship with the at least one second in-vehicle terminal in a valid time period;

recording a quantity of times of establishing the second relationship with the third in-vehicle terminal in the valid time period; and

recording the information exchanged with the at least one second in-vehicle terminal or the third in-vehicle terminal.

2. The method according to claim 1, wherein establishing, by the first in-vehicle terminal, the first relationship with at least one second in-vehicle terminal that receives the broadcast message comprises:

receiving, by the first in-vehicle terminal, a first relationship establishment request message sent by the at least one second in-vehicle terminal, wherein the first relationship establishment request message comprises the identifier of the first in-vehicle terminal and an identifier of the at least one second in-vehicle terminal; and

sending, by the first in-vehicle terminal, a first relationship establishment confirmation message to the at least one second in-vehicle terminal according to the identifier of the at least one second in-vehicle terminal, to establish the first relationship, wherein the first relationship establishment confirmation message comprises the identifier of the first in-vehicle terminal and the identifier of the at least one second in-vehicle terminal.

3. The method according to claim 2, wherein establishing, by the first in-vehicle terminal, the second relationship with the third in-vehicle terminal selected from the at least one second in-vehicle terminal comprises:

sending, by the first in-vehicle terminal, a second relationship establishment request message to the third in-vehicle terminal, so that the third in-vehicle terminal determines, according to the generated rule, whether to agree to establish the second relationship; and

receiving, by the first in-vehicle terminal, a second relationship establishment confirmation message sent by the third in-vehicle terminal, to establish the second relationship.

4. The method according to claim 1, wherein the generated rule comprises at least one of the following:

a quantity of times that the first in-vehicle terminal and the at least one second in-vehicle terminal share a same destination that is greater than a first specified threshold according to destination information comprised in the information;

a quantity of times that the first in-vehicle terminal establishes the first relationship with the at least one second in-vehicle terminal that is greater than a second specified threshold;

or

a quantity of times that the first in-vehicle terminal establishes the second relationship with the third in-vehicle terminal that is greater than a third specified threshold.

5. The method according to claim 4, further comprising updating, by the first in-vehicle terminal, a relationship with the third in-vehicle terminal that does not meet the generated rule in a valid time period or that is indicated by a relationship change indication received by user input to the first relationship.

6. The method according to claim 1, wherein the first relationship is an encounter relationship, and wherein the second relationship is a friend relationship.

7. The method according to claim 1, wherein the broadcast message further comprises a vehicle type of an in-vehicle terminal that exchanges information with the first in-vehicle terminal, and a vehicle type of the at least one second in-vehicle terminal is consistent with the vehicle type carried in the broadcast message.

8. The method according to claim 1, further comprising:

separately sending, by the first in-vehicle terminal, positioning information request to the at least one second in-vehicle terminal or the third in-vehicle terminal that has established the first relationship and/or the second relationship with the first in-vehicle terminal;

receiving, by the first in-vehicle terminal, at least one of positioning information sent by the at least one second in-vehicle terminal and the third in-vehicle terminal; and

determining, by the first in-vehicle terminal, a current location of the first in-vehicle terminal according to at least one of the positioning information sent by the at least one second in-vehicle terminal and the third in-vehicle terminal.

9. An in-vehicle terminal, comprising:

a memory comprising instructions; and

a processor coupled to the memory, wherein the instructions cause the processor to be configured to;

automatically send a broadcast message, wherein the broadcast message comprises an identifier of a first in-vehicle terminal;

establish a first relationship with at least one second in-vehicle terminal that receives the broadcast message;

select a third in-vehicle terminal from the at least one second in-vehicle terminal to establish a second relationship based on a rule generated by the first in-vehicle terminal;

establish the second relationship with the third in-vehicle terminal from the at least one second in-vehicle terminal in response to selecting the third in-vehicle terminal from the at least one second in-vehicle terminal based on the rule generated by the first in-vehicle terminal;

separately exchange first information corresponding to the at least one second in-vehicle terminal and second information corresponding to the third in-vehicle terminal with each of the at least one second in-vehicle terminal and the third in-vehicle terminal, respectively, wherein the first information comprises non-privacy information, and wherein the second information comprises privacy information and non-privacy information;

record, in a relational database according to at least one of the identifier of the at least one second in-vehicle terminal and an identifier of the third in-vehicle terminal, a quantity of times of establishing the first relationship with the at least one second in-vehicle terminal in a valid time period;
