[0055] 1. When the vehicle is driving, the vehicle position is monitored in real time through GPS or cellular network positioning to obtain the real-time vehicle position of the vehicle.

[0056] S2. According to the real-time vehicle position, obtain historical traffic accident information and real-time traffic conditions of the road within a preset distance in front of the vehicle; wherein the historical traffic accident information includes: the location of historical traffic accidents and the number of historical traffic accidents; the real-time traffic conditions include: the current traffic flow and the critical point of the current traffic light change;

[0057] 2. The vehicle map is pre-connected with the data system of the traffic management department or emergency rescue agency to collect and store the historical traffic accident information of the road in the TBOX storage module. The traffic management department can open specific application program interfaces, and the vehicle map service provider can apply to use these interfaces to achieve data interaction through interface connection. The historical traffic accident information of the road includes the location of historical traffic accidents, the number of historical traffic accidents, etc. Then, according to the real-time vehicle position, the historical traffic accident information of the road within a preset distance in front of the vehicle is obtained.

[0058] Then, the real-time traffic conditions of the road within the preset distance in front of the vehicle are obtained: the current traffic flow and the critical point of the current traffic light change. Among them, the traffic department data sharing: the traffic management department has set up a large number of monitoring cameras, speed measuring equipment, etc. on the road. These devices can monitor the current traffic flow and the critical point of the current traffic light change in real time. Map software companies cooperate with the traffic department to obtain these official traffic data and integrate them into the map to provide users with more accurate real-time road traffic conditions.

[0059] S3. According to the real-time vehicle position of the vehicle and the location of historical traffic accidents within a preset distance in front of the vehicle, the distance between the vehicle and the location of historical traffic accidents within the preset distance in front of the vehicle is obtained, and according to the number of historical traffic accidents within the preset distance in front of the vehicle, the current traffic flow and the critical point of the current traffic light change, whether there is a traffic accident risk within the preset distance in front of the vehicle;

[0060] Preferably, the method of judging whether there is a traffic accident risk within a preset distance in front of the vehicle based on the number of historical traffic accidents within a preset distance in front of the vehicle, the current traffic flow and the current traffic light change critical point includes: obtaining the historical average traffic flow within the preset distance in front of the vehicle; judging that there is a traffic accident risk within the preset distance in front of the vehicle when the number of historical traffic accidents within the preset distance in front of the vehicle is greater than a preset accident number threshold, the current traffic flow within the preset distance in front of the vehicle is greater than a preset traffic flow threshold, the difference between the current traffic flow within the preset distance in front of the vehicle and the historical average traffic flow is greater than a preset flow difference threshold, or there is a current traffic light change critical point within the preset distance in front of the vehicle.

[0061] 3. If the vehicle is about to reach the location of a historical traffic accident, or the system predicts that there may be a risk of a traffic accident in the area where the vehicle is approaching, the pre-start function of the ECALL system will be automatically triggered.

[0062] According to the obtained historical traffic accident locations, historical traffic accident frequency, current traffic flow and current traffic light change critical point, if multiple accidents occur (i.e., the historical traffic accident frequency within a preset distance in front of the vehicle is greater than the preset accident frequency threshold), it is judged that there is a risk of traffic accidents; areas with large traffic flow (i.e., the current traffic flow within a preset distance in front of the vehicle is greater than the preset traffic flow threshold) are judged to have a traffic accident risk; fluctuating traffic flow (i.e., the difference between the current traffic flow within a preset distance in front of the vehicle and the historical average traffic flow is greater than the preset traffic flow difference threshold) is judged to have an accident or road construction and a traffic accident risk; the traffic light change critical point (i.e., the current traffic light change critical point exists within the preset distance in front of the vehicle) is judged to have a traffic accident risk (risks: rear-end collision, running a red light, car accident, rollover, scratch).

[0063] S4. When it is detected that the distance between the vehicle and the location of a historical traffic accident is less than a preset distance threshold, or there is a risk of a traffic accident within a preset distance in front of the vehicle, the preset software program and system data of the ECALL system are loaded into the memory, and the ECALL system is pre-started.

[0065] 4. If the vehicle is about to reach the site of a historical accident, or the system predicts that there may be risks in the area where the vehicle is approaching, the pre-start function of the ECALL system is automatically triggered. TBOX pre-starts by loading the relevant software programs of the ECALL system and the necessary data into the memory in advance to reduce the startup time.

[0066] After the ECALL system is pre-started, it can also collect and transmit more information about the accident, such as vehicle model, number of passengers, accident type, etc. The real-time vehicle location, vehicle model, number of passengers and possible accident type of the vehicle are stored in the preset vehicle accident information database. This information helps rescue agencies to prepare in advance and dispatch appropriate rescue personnel and equipment.

[0067] Preferably, the method further comprises: obtaining historical driving data of the vehicle; wherein the historical driving data comprises: the historical driving trajectory of the vehicle, the instantaneous speed at each moment in the historical driving process of the vehicle, and the average speed of each historical trip of the vehicle; analyzing and obtaining the vehicle's common route according to the vehicle's historical driving trajectory, obtaining the maximum instantaneous speed of the vehicle in the historical driving process according to the instantaneous speed at each moment in the historical driving process of the vehicle, and obtaining the total average speed of the vehicle in all historical trips according to the average speed of each historical trip of the vehicle; judging whether the vehicle currently has a risk of a traffic accident according to the common route of the vehicle, the maximum instantaneous speed of the vehicle in the historical driving process, and the total average speed of the vehicle in all historical trips; judging whether the vehicle currently has a risk of a traffic accident when it is detected that the current driving trajectory of the vehicle deviates from the common route of the vehicle, the current driving speed of the vehicle is greater than the maximum instantaneous speed of the vehicle in the historical driving process, or the difference between the current driving speed of the vehicle and the total average speed is greater than a preset speed difference threshold, judging that the vehicle currently has a risk of a traffic accident, loading the preset software program and system data of the ECALL system into the memory, and pre-starting the ECALL system.

[0068] In the above-mentioned traffic accident prediction process, the historical driving data of the vehicle can also be obtained to analyze the driving habits of the owner and statistical laws: according to the historical driving trajectory of the vehicle, the vehicle's common route is analyzed, the maximum instantaneous speed of the vehicle in the historical driving process is obtained according to the instantaneous speed of the vehicle at each moment in the historical driving process, and the total average speed of the vehicle in all historical trips is obtained according to the average speed of each historical trip of the vehicle. Then, according to the common route of the vehicle, the maximum instantaneous speed of the vehicle in the historical driving process and the total average speed of the vehicle in all historical trips, it is judged whether the vehicle currently has a traffic accident risk; when it is detected that the current driving trajectory of the vehicle deviates from the common route of the vehicle, the current driving speed of the vehicle is greater than the maximum instantaneous speed of the vehicle in the historical driving process, or the difference between the current driving speed of the vehicle and the total average speed is greater than the preset speed difference threshold, it is judged that the vehicle currently has a traffic accident risk, the preset ECALL system software program and system data are loaded into the memory, and the ECALL system is pre-started.

[0069] It can be seen that the present invention provides an ECALL system pre-start method, and the following beneficial effects can be achieved through the present invention:

[0070] 1. Quick rescue: In the event of an emergency, the pre-activated ECALL system can immediately trigger the sending of a distress signal, greatly shortening the time from the occurrence of the accident to the rescue agency receiving the distress message;

[0071] 2. Reduce manual operation time: In an emergency, the driver may be unable to manually start the ECALL system in time due to injury or panic. The pre-start system does not require manual operation by the driver and automatically enters the working state, ensuring that the distress signal can be sent out in time;

[0072] 3. Accurate positioning: The pre-activated ECALL system can start acquiring vehicle location information earlier and continuously update it, which enables rescue agencies to more accurately determine the location of the accident and reduce the time spent searching for the accident scene;

[0073] 4. Provide more information: In the pre-startup phase, the system can collect and transmit more information about the accident, such as vehicle model, number of passengers, accident type, etc. This information helps rescue agencies prepare in advance and dispatch appropriate rescue personnel and equipment.
