And step S303, if the vehicle is different from the current destination, generating historical driving information after the vehicle reaches the current destination.

If not, the historical travel information of the vehicle is not stored in the previous database, so the historical travel information is generated and the steps S10 to S20 are repeated.

And step S105, acquiring any one or more of preset historical driving information of a specific turn and historical driving information of an intersection. Through the step, the historical information of the specific position can be obtained, and in the using process of the road, the conditions of slow vehicle running and large vehicle flow can occur at the positions of partial curves, intersections where a plurality of branches intersect and the like of the road, so that the positions of the curves, the intersections and the like are blocked, and the preset historical driving information of the specific turn and the historical driving information of the intersections can be collected and counted.

The historical driving information is obtained through the multiple modes, the types and the quantity of the historical driving information are expanded, and the matching degree of the current driving information and the historical driving information is improved.

In step S20, the method includes:

step S201, presetting a database, and dividing the database into a plurality of storage units, wherein each storage unit has different index information;
