[0066] Step S44: According to the statistical analysis and collation of the above steps, the emergency prediction module calculates the emergency impact index U through a formula; wherein:

[0067]

[0068] Where k is the coefficient value, which is a constant greater than 0. It can be seen from the formula that the emergency impact index is proportional to the number of times judged as emergencies within the period, the average travel distance of emergencies within the period, and the ratio of marked emergencies to all emergencies.

[0076] Step S6 further comprises the following steps:

[0077] Step S61: The system estimates the remaining cruising range S of the current vehicle based on the actual power consumption per 100 kilometers and the current remaining power of the current vehicle;

[0078] Step S62: Taking "day" as a cycle, the system retrieves all the planned travel events of the car owner before the next cycle and all the trip information of the daily fixed travel corresponding to the required total mileage c;

When the frequency and impact of the emergency events in the current car owner's car use process are relatively large, the timing of energy replenishment will be advanced to reserve as much reserve power as possible for use in emergencies; the comprehensive energy replenishment cost index R of the car owner is inversely proportional to the timing of energy replenishment. When the energy replenishment cost is higher, the time cost of the car owner's energy replenishment will be greatly increased, and the control in the formula will affect the delayed energy replenishment timing; ultimately, it can achieve the role of fully, comprehensively and accurately making decisions for the car owner, achieving a worry-free effect;

Step S42: Also taking half a year as a cycle, the travel distances of all emergencies within half a year are counted in the historical event log library, and the average travel distance l of the emergencies within the period is calculated by the summation and average formula; Step S43: then count and calculate the ratio b of the marked emergency events to all emergency events in the historical event log library; Step S44: According to the statistical analysis and collation of the above steps, the emergency prediction module calculates the emergency impact index U through a formula; wherein: Step S5: Further retrieve the owner's energy replenishment facility construction status through the Internet of Vehicles technology, analyze and evaluate the owner's rapid energy replenishment cost index when traveling, and output the family energy replenishment cost fixed index when recharging at home; The step S5 further comprises the following steps: Step S51: The system retrieves the density of charging piles near the car owner's permanent residence through the Internet, including the density of charging piles p1 within 5 kilometers of the car owner's permanent residence and the density of charging piles p2 within 200 kilometers of the car owner's permanent residence; Step S52: the system further retrieves the electricity price of charging piles near the car owner's permanent residence area, and calculates the average electricity price j1 of charging piles within a radius of 5 kilometers and the average electricity price j2 of charging piles within a radius of 200 kilometers; Step S53: By formula Calculate the owner's short-distance rapid energy replenishment cost index R1; through the formula Calculate the cost index R2 of long-distance rapid energy replenishment for vehicle owners; Step S54: outputting the household energy replenishment cost fixed index R3; Step S55: When the owner's family has a fixed charging parking space, the charging cost evaluation module outputs a comprehensive charging cost index When the owner's family does not have a fixed charging parking space, the charging cost assessment module outputs a comprehensive charging cost index Step S6: When the vehicle owner is using the vehicle, the system analyzes and calculates the energy replenishment timing, and when it is determined that the energy replenishment timing has been reached, the energy replenishment trip is automatically planned on the vehicle computer through the energy replenishment trip output module; The step S6 further comprises the following steps: Step S61: The system estimates the remaining cruising range S of the current vehicle based on the actual power consumption per 100 kilometers and the current remaining power of the current vehicle; Step S62: Taking "day" as a cycle, the system retrieves all the planned travel events of the car owner before the next cycle and all the itinerary information of the daily fixed travel corresponding to the required total mileage c; Step S63: Calculate the remaining cruising range S0 until charging is ready by using a formula; where S0 satisfies: Where δ is the control parameter of the remaining cruising range S0 at the time of charging, which is a constant greater than 0, and S max The maximum remaining range given by the system when the charging time is reached, when S0 is greater than S max When S0=S max Analyze and calculate the results for energy replenishment opportunities; Step S64: When Sc≤S0, the energy replenishment timing calculation module triggers an electrical signal, and the system controls the vehicle computer to automatically plan the vehicle computer navigation to a nearby charging station. The owner receives the system planning information to perform rapid energy replenishment of the electric vehicle or home charging.
