The vehicle dealer database 30 includes a plurality of vehicle accounts 31, and each vehicle account 31 corresponds to a vehicle 20. The vehicle account 31 stores identification data of the vehicle 20 and data transmitted through the ADAS 25. The identification data of the vehicle 20 can be an identification code corresponding to the ADAS 25, or data such as the license plate number, model, horsepower, tonnage, etc. of the vehicle 20 can be additionally recorded. The data transmitted by the ADAS 25 mainly includes GPS trajectories. As shown in FIG. 1, the data transmitted by the ADAS 25 may still include the image taken by the camera 21 on the vehicle 20, or the gravity sensor (G-sensor) 22 or the gyroscope 23 on the vehicle 20. The data transferred.

A data analysis system 40 is connected to the vehicle dealer database 30. As shown in FIG. 2, the data analysis system 40 includes:

A trajectory construction unit 41 is connected to the vehicle dealer database 30 and is used to receive GPS trajectory data of the vehicle account 31. The trajectory construction unit 41 constructs the vehicle 20 according to the GPS trajectory data and the corresponding time, and cooperates with the map. Whereabouts. The whereabouts of the vehicle 20 include the road sections traveled by the vehicle 20 at various times. Therefore, the location of the vehicle 20 at a certain point in time can be learned from the whereabouts of the vehicle 20.

Sudden deceleration refers to rapid deceleration, and sudden braking refers to the state of stopping the vehicle after deceleration. The special situation analysis unit 42 sets corresponding upper limit values for these four special situations. When the acceleration, deceleration, braking or turning of the vehicle 20 exceeds the corresponding upper limit value, a specific mark is given, mainly to mark the vehicle 20 The time and location of the special situation. If necessary, the number of occurrences of each special situation in a period can be calculated.

The judgment methods of sudden acceleration, sudden deceleration, and sudden braking are calculated by GPS position and relative time point. When the upper limit is exceeded, the camera 21 on the vehicle 20 is ordered to transmit the video recorded a set period of time before the time point (for example, 10 seconds before the sudden acceleration occurs). Among them, acceleration, deceleration, braking or turning can be calculated on the ADAS 25 end or on the cloud server 10.

The analysis of the sharp turn by the special situation analysis unit 42 is mainly based on the data transmitted by the gyroscope 23. When the turning angle exceeds the set angle within a certain set period of time, it is regarded as a sharp turn.

A historical data statistics unit 43, used to count the number of special circumstances of a vehicle 20 (or a driver) in a certain period of time or a certain road section, such as the number of rapid accelerations in the current month,

Or the number of rapid decelerations during the entire journey of the expressway from south to north, etc. Historical data and driving records can also be used to estimate vehicle driving loss.

The vehicle dealer database 30 still receives image data from the vehicle 20. Since the transmission of image data requires a great amount of communication, the ADAS 25 only transmits the image data to the vehicle dealer database 30 and stores it in a specific vehicle account 31 only under certain circumstances.

The ADAS 25 sets the following conditions to transmit image data: sudden braking, sudden deceleration, and when the value of the gravity sensor 22 changes greatly. When the value of the gravity sensor 22 changes suddenly, it may be a crash. The ADAS 25 setting must transmit the image data of the previous period of time at the time when the above-mentioned situation occurs to the vehicle dealer database 30 for subsequent analysis of the situation. For example, images within 10 seconds before the occurrence of this situation must be transmitted.

A map display 50 is connected to the data analysis system 40. The map display 50 is used to display the data obtained by the data analysis system 40, including the path traveled by the vehicle 20 on the map, and mark the corresponding time. Moreover, when a specific location of the route displayed on the map display 50 is clicked, the data analysis results of the vehicle 20 at the specific location, such as safe driving, rapid acceleration, rapid deceleration, rapid braking, and rapid turning, can be displayed. In addition, the map display 50 can also display statistical information of the vehicle 20 during the entire driving process, such as the number of stops, the number of rapid accelerations, the number of rapid decelerations, the number of rapid braking, the number of sharp turns, and so on. The application of the map display 50 can help to clearly understand the entire driving situation.

A driving behavior analysis unit 60 is connected to the data analysis system 40. The driving behavior analysis unit 60 is used to retrieve data obtained by the data analysis system 40 and analyze the driving behavior of the vehicle 20. The results of these analyses help provide the driver himself, enable him to improve his driving habits, and remind him of the things he should pay attention to. On the other hand, the results of these analyses can also be provided to insurance companies. The company allows the insurance company to assess the risk of the driver while driving based on the driving behavior, and to consider other data to set different insurance rates for different drivers. FIG. 3 shows an application schematic diagram of this case, which shows that the data obtained by the data analysis system 40 obtains the driving behavior analysis report 100 through the driving behavior analysis unit 60, and performs the rate calculation program 120 in cooperation with the insurance company data 110.

In this case, the data analysis system 40 and the map display 50 in Figures 1 and 2 are located in the cloud server 10, but this is not used to limit the scope of the case. The data analysis system 40 and the map display 50 can also Located outside the cloud server 10.
