In the sharing and interaction of vehicle information, in addition to the need for users to perceive the state of the vehicle and themselves in a timely manner to understand their own driving conditions and avoid accidents, users and some social organizations need to obtain other people's vehicle state information to perceive traffic conditions, such as , obtain the vehicle status information of friends to timely perceive whether some roads are congested, and obtain the status information of many vehicles to statistically analyze the current urban traffic conditions; users need to obtain other people's vehicle status information for social interaction, for example, asking friends for their geographic location Location information, monitor the driving habits of friends, remind and correct them, and remind friends of the abnormal situation of the vehicle; users need to publish their own vehicle status information to interact with others socially, for example, users publish vehicle breakdown information to seek help and rescue from others, users publish Vehicle breakdown information to get technical support from others, and users publish vehicle location information to get other people's route guidance.

In terms of safe driving, users need to ensure the safety of vehicle driving when sharing and interacting with vehicle information. The sharing of vehicle information needs to change from passive information acquisition to active information acquisition. The interaction of vehicle information needs to minimize manual intervention and Operation, so that the user can concentrate on the process of driving the vehicle and ensure safe driving.

The existing vehicle information publishing system can collect the basic data information of the vehicle, and then provide the collected information to the vehicle owner through a specific application program, so that the vehicle owner can understand his own vehicle information. However, there are still some problems in the existing vehicle information publishing system. Specifically, the vehicle information released by it is simple basic vehicle information, which is not processed and analyzed in real time in combination with the current external situation, so that ordinary vehicle users cannot obtain real-time And judge the advanced information of the vehicle and the real-time driving status of the vehicle; the vehicle information is only released to the vehicle user, and it is impossible or difficult for others to actively obtain the vehicle status information other than themselves, which cannot meet the sharing requirements of the vehicle user for vehicle information; When a user wants to obtain other people's vehicle information, he needs to manually send a query request to the other party. When faced with other people's vehicle information query, the vehicle user needs to manually complete the information query and manually inform others of the results. The interaction of vehicle information The process is cumbersome and cannot meet the user's interactive needs for vehicle information; at the same time, these processes require the absolute intervention of the user, which interferes with the driving vehicle user and poses a threat to the safe driving of the vehicle, and cannot meet the user's demand for safe driving. need.

Aiming at the problems existing in the existing vehicle information release system, the social network provides achievable technical support for users to share and interact with vehicle information and their needs for safe driving. Social Networking (Social Networking) refers to Internet applications that use certain social relationships or common interests as a link to provide communication and interactive services for online aggregated users in various forms. It has the characteristics of sharing, interactivity and openness.

At the same time, record the The type of information subscribed to.

The information push unit is used to generate personalized information results for the user according to the pre-set vehicle information publishing rules and the types of information subscribed by the user after the information processing is completed, and then push the information results to the external social network through the Internet Server, displayed to message subscribers.

The social interaction unit is used to obtain the user's interaction intention from the external social networking site server through the Internet, obtain the type of information the user wants to query through the method of keyword matching, and then query the information, and push the query results to the querying user in real time on the social network through the Internet .

The social network communication unit encapsulates the communication interface of the social networking site, and is used for transmitting and interacting with the external social networking site server through the Internet according to the communication protocol and mechanism of the social networking site.

As shown in Figure 2, the release method of vehicle information in this embodiment is as follows:

First, the external situational information collection unit collects external situational information from the Internet in real time every 1 minute. In this example, the external situational information collected includes oil prices, weather, road conditions, and current road speed limits. For example, the data collected at a certain moment is: Hangzhou April 14, 2012 16:00 93# The oil price of gasoline is 7.88 yuan/liter, the weather is cloudy, the current road condition is an expressway, and the road speed limit standard is 60Km/h ~120Km/h.

The vehicle information collection unit collects vehicle information through the on-board computer and external sensors every 30 seconds. In this example, the basic information of the vehicle itself collected includes vehicle speed, steering wheel, brake, gear position, accelerator, headlights, handbrake, ignition, clutch , Whether to wear seat belts and left and right steering information, vehicle situation information includes temperature, humidity, light, geographical location and motion status information. For example, the data collected at the same time is: the vehicle speed is 100Km/h, the steering wheel is +0.1 ("+" marks the right deviation, "-" marks the left deviation, the total range is -1~+1), the brake is 0 , the gear position is 3, the throttle is 0.4 (the total range is 0~1), the headlight is 0, the handbrake is 0, the ignition is 0, the clutch is 0, the seat belt is 1, and the left and right steering is +0.2 (“+” sign Right offset, "-" mark left offset, the total range is -1~+1), the temperature is 23°, the humidity is 38%, the light is 350Lux, the geographical location is Desheng intersection, and the motion state is acceleration.

Next, classify the vehicle information to be released. In this example, the collected vehicle information and statistically analyzed information are divided into three categories, namely vehicle data information, driving status information and safety warning information. Vehicle data information includes vehicle speed, steering wheel, brake, gear position, accelerator, lights, handbrake, ignition, clutch, whether to wear seat belts, left and right steering information, temperature, humidity, light and geographical location; driving status information includes motion status, average Vehicle speed, fuel consumption/km, cost/km, whether it is in a traffic jam, and whether it is broken down; safety warning information includes whether the vehicle speed exceeds the standard, whether it is in a safe driving state, and vehicle failure information.

Then, combined with the collected situational data information and vehicle information, statistical analysis of information is carried out according to certain rules. For example, in this instance,

The formula for calculating the average vehicle speed is:

${\mathrm{<span\; class="notranslate">\; V</span>}}_{\mathrm{<span\; class="notranslate">\; average</span>}}<span\; class="notranslate">\; =</span>{\mathrm{<span\; class="notranslate">\; \&Sigma;</span>}}_{\mathrm{<span\; class="notranslate">\; i</span>}<span\; class="notranslate">\; =</span>\mathrm{<span\; class="notranslate">\; 1</span>}}^{\mathrm{<span\; class="notranslate">\; no</span>}}{\mathrm{<span\; class="notranslate">\; V</span>}}_{\mathrm{<span\; class="notranslate">\; i</span>}}<span\; class="notranslate">\; /</span>\mathrm{<span\; class="notranslate">\; no</span>}<span\; class="notranslate">\; ;</span>$

The formula for calculating the amount spent/km is:

Cost _average = N _{total fuel consumption} * P _{oil price} / L _{total travel}

The rules for judging whether the vehicle speed exceeds the standard are as follows:

Tag _overspeed = (V _aberage ≤ V _{speed limit upper limit} ) && (V _average ≥ V _{speed limit lower limit} );

According to the formula and calculation rules, the calculated average vehicle speed V _average = 113.5Km/h, the cost/km Cost _average = 0.52 yuan/km, whether the vehicle speed exceeds the standard Tag _Overspeed = True, that is, the vehicle speed does not exceed the standard.

The processed information is released according to the rules defined by the vehicle user when it is released, and the information is pushed according to the user's subscription information. The device allows the vehicle user to define the release rules of the information. At the same time, the user can also independently choose the type of information to be received; each type of information and each type of information has its release rules. The information release rules include whether the information can be released, information Frequency of publication and type of information to be published. For example, in this instance, the publishing rules for vehicle data information are:

Types of information subscribed by a user A:

After the information is processed, the information is released and pushed according to the rules of publishing and subscription. The information publishing process is shown in Figure 2, and the specific steps are as follows:

(1) Query the information table subscribed by each information subscriber to obtain the type of information subscribed;

(2) Query the information release rules for each type of information subscribed to. If the release is not allowed, then judge the next type of information. If the release is allowed, the information data will be obtained and converted into the set information Publish form, loop until all the information subscribed by the user is obtained;

(3) After the information is obtained, push the information result to the external social network server.

In this example, for user A, he has subscribed to the vehicle speed information, so he inquires about the publishing rules of the vehicle speed information. Since the vehicle speed information cannot be released in the publishing rules, he enters the data acquisition process of the next information. Finally, the data results of all the information subscribed by user A are obtained and sent to the social network server through the social network communication unit.

The social interaction unit can receive user interaction requests, and then automatically make intelligent replies and responses, including a remote vehicle information query mechanism.

As shown in Figure 4, the remote vehicle information query method obtains user query statements through social platforms, analyzes the user's query intent through keyword matching, and then obtains the type of information to be queried according to the user's query intent, and queries the corresponding vehicle information, and then respond to the user's corresponding query. The specific process is as follows:

1. Use the general information query interface of the open interface of social platforms such as Sina Weibo, Tencent Weibo and other broadcast social networks and open source IM (such as Spark, Instantbird) and instant messaging software such as mobile phone SMS gateways to obtain each unread user Asked for information. For a broadcast social network, the roll call information of the vehicle information account is obtained through the roll call information query interface; for instant messaging software, the dialogue request information for the vehicle information account is obtained through the dialogue information query interface;

2. Through the method of keyword matching, use the obtained user's roll call or dialogue information to analyze the user's query intention, where the user's intention includes querying various information of vehicle information;

3. According to the user's query intention, the corresponding vehicle information is obtained through the information management and control unit of the present invention, and the general reply interface of the open platform of the social network is used to reply to the corresponding information of the user. For broadcast social networks such as Sina Weibo and Tencent Weibo, reply to the Weibo; for instant messaging software such as open source IM and SMS gateways, reply to the conversation. Return to step 2.
