the left-right split screen comprises a vehicle-mounted screen, a first display area and a second display area, wherein the vehicle-mounted screen is divided into the first display area and the second display area along the horizontal direction, and the first display area is positioned on one side close to a driver seat;
the vertical split screen comprises the steps that the vehicle-mounted screen is divided into a third display area and a fourth display area along the vertical direction, and the third display area is located above the fourth display area;
the steps of acquiring the short message content and the driving information of the vehicle and judging whether the short message content needs to be displayed on the vehicle-mounted screen in a split screen mode comprise the following steps:
acquiring a running route segment with a next preset time length in the navigation route map as a segment to be analyzed, and setting the path length of the segment to be analyzed as L a ；
Obtaining the running times M of the vehicle in the latest period z And the number of times M of driving including the section to be analyzed in the driving route in each driving 0 Then the first driving reference X = M for the section to be analyzed 0 /M z ；
Collecting waiting for sortingDividing the section to be analyzed into k sections to be analyzed by each turnout, and setting the path length of the ith section to be analyzed as L i ，
Respectively collecting traffic flow conditions of each lane in each section to be analyzed in the same time period in the latest period, and setting the traffic flow of the lane in which the ith section to be analyzed is the same as the advancing direction of the vehicle and the running path direction as C i The traffic flow of the lane having the same traveling direction as the vehicle but different traveling path direction is D i ，
Then the second driving reference component of the segment to be analyzed
，
Then the integrated driving reference amount Z =0.68 x +0.32 y;
if the comprehensive driving reference quantity is smaller than the comprehensive driving reference threshold value, the vehicle-mounted screen is divided into an upper screen and a lower screen, the short message content is displayed in a fourth area, and the navigation route map is displayed in a third area;
otherwise, the vehicle-mounted screen is split left and right, the short message content is displayed in a first area, and the navigation route map is displayed in a second area;
the analyzing the received short message content to obtain the short message identifier comprises the following steps:
collecting keywords of short message content and sender, obtaining the short message content sent to driver's mobile terminal by sender, and extracting keywords of each historical short message content,
if the similarity between the keywords of the historical short message content and the keywords of the currently received short message content is larger than or equal to the similarity threshold value, marking the short message content with a first mark,
otherwise, marking the short message content with a second mark;
the displaying the short message content in the first area comprises: acquiring the distance length from the nearest fork junction to the current position in the advancing direction, wherein if the distance length is greater than the distance reference length, the area of the first region is greater than that of the second region;
the displaying the short message content in the fourth area comprises: and acquiring the distance length from the nearest fork road to the current position in the advancing direction, wherein if the distance length is less than the distance reference length, the area of the fourth area is less than that of the third area.
