Description

A method for collecting active vehicle safety information and an information service system

technical field

The invention relates to a vehicle information service system, in particular to a method for collecting vehicle active safety information and a vehicle information service system.

Background technique

As the number of cars continues to increase and the frequency of people driving cars increases, users have higher and higher requirements for follow-up services for car consumption, so the car information service system (usually called Telematics) came into being. 

Through the investigation and statistics of vehicle safety accidents, most of the accidents are caused by negligence in the first 3 seconds of the accident. In order to effectively avoid these accidents, there are corresponding applications of lane departure alarm, anti-collision alarm and auxiliary braking, pedestrian detection and anti-collision alarm on the car. The application of these systems provides users with forward-looking safety. Alarm prompt, effectively reducing the incidence of accidents. However, most common vehicle models do not possess these types of alarm systems, and the vehicle types (users) that do not possess these types of alarm systems should also enjoy the safety results brought by this type of alarm system, which has not yet been involved in the prior art.

When using GPS navigation, it is often encountered that the route does not match the actual situation. For example, the indicated road is impassable due to diversion, construction, etc. question.

In the prior art, most automobile information service systems can provide services such as GPS navigation, weather entertainment information, vehicle condition detection, driving safety information, and rescue. Among them, the driving safety information is all safety reminder information on road speed limit, fatigue driving reminder, maintenance, etc., and it is not timely to reflect information such as newly opened roads and road rerouting.

The relatively mature Shanghai GM "On Star" car-specific information service system can provide a number of characteristic information services, such as vehicle remote diagnosis, stolen vehicle alarm and tracking, accident rescue assistance, etc., but safety tips such as how to prevent driving accidents In addition, the navigation information provided by the GPS navigation system is single, and the navigation map downloaded to the user terminal is too simple. Another example is that the publication date is January 06, 2010, and the publication number is CN101621735, which discloses such a technical solution. The vehicle integrated information system based on the third-generation mobile communication includes a server and a vehicle-mounted terminal that communicate through a 3G network. The terminal includes: the automobile bus interface module, which is connected to the internal control bus of the automobile through the OBD interface, obtains the driving information of the vehicle and transmits it to the embedded control module; the 3G mobile communication modem module; the embedded control module, obtains the driving information of the vehicle and Process, carry out interactive communication with server by the 3G mobile communication modem module connected with it; Server comprises: information receiving module, receives the information of the vehicle-mounted terminal transmitted by 3G network; Information storage module, stores information receiving module information and application information; The function module is used to realize application functions such as vehicle positioning, map navigation, real-time route planning, and vehicle anti-theft; the information publishing module is used to send the information provided by the server to the vehicle terminal. However, this solution also has deficiencies. One is that there is no safety assessment for specific road sections, so active safety information in this area cannot be provided; Ways and means of how to obtain information on road construction and intersection traffic rules modification.

Contents of the invention

The main purpose of the present invention is to provide a method for collecting active safety information of automobiles and an information service system, so that the automobile information service system can have active safety information prompts to prevent accidents, as well as the functions of timely correcting and updating GPS navigation maps.

The present invention mainly solves the problems in the prior art through the following technical solutions, a method for collecting active safety information of automobiles, comprising:

(A) Vehicles equipped with lane departure warning system, front anti-collision warning system, pedestrian detection and anti-collision warning system will send the warning information, vehicle speed at the time of warning, and GPS positioning information to the remote service platform through the wireless communication network;

(B) The remote service platform counts the alarm events that occur in each road section, and calculates the probability of occurrence of the corresponding alarm event on the road section where the alarm is located, and stores the calculation results and road section information in the database;

(C) When the vehicle-mounted user terminal uses the remote service platform for navigation, the remote service platform will download the planned route and the alarm event occurrence probability of each road section on the route to the vehicle-mounted user terminal through the wireless communication network, and perform security checks before entering the road section. Driving Tips.

The vehicle-mounted user terminal is divided into an information collection vehicle-mounted terminal and an ordinary vehicle-mounted terminal. ,Information collection The vehicle-mounted user terminal is equipped with lane departure warning system, front anti-collision warning system, pedestrian detection and anti-collision warning system, GPS positioning device, controller, display, speaker device, wireless communication module, controller management and control The various components of the vehicle user terminal work in harmony. Ordinary vehicle-mounted user terminals are not equipped with lane departure warning system, front collision warning system, pedestrian detection and collision prevention warning system. Information collection The on-board client sends the alarm information, vehicle speed and GPS positioning information of the alarm system to the remote service platform, and the remote service platform performs alarm event statistics and evaluation of dangerous road sections on the received information. The navigation map is displayed on the monitor, the voice prompt is played by the speaker device, and the remote service platform is equipped with a GPS navigation map correction unit and a database to timely correct and supplement the navigation map, and write information and data such as alarm information, road section evaluation, and dangerous road sections. into the database.

Preferably, the vehicle-mounted user terminal is provided with a newly opened road GPS positioning information sending key and an unused road GPS positioning information sending key. When the driver finds a newly opened road and is driving on the newly opened road, he operates the button to send the GPS positioning information of the newly opened road. The correction unit makes corrections and supplements in time.

Preferably, the wireless communication network is the operator's 3G communication network, and its high-speed data transmission capability is used for real-time transmission of data and navigation maps.

The beneficial effect brought by the present invention is that the automobile information service system has active safety information prompts for all users under the system to prevent accidents, displays on the display for high-accident road sections, and gives voice prompts before entering dangerous road sections, effectively improving The safety of the vehicle is improved, and the GPS navigation map is corrected and supplemented in time, which further increases the practicability of the GPS navigation.
