Referring to fig. 1, a flow chart of a vehicle driving route navigation method is provided in an embodiment of the present application, and is applied to a server. As shown in fig. 1, the method of the embodiment of the present application may include the following steps:
s101, receiving a starting point coordinate and an end point coordinate sent by an APP mobile terminal aiming at a server;
the server may be a remote server, and is mainly used for performing related calculation according to the position data sent by the APP mobile terminal. The APP mobile terminal can be a mobile phone or a driving computer on a vehicle and is mainly used for positioning a starting point coordinate, receiving a terminal point coordinate input by a user and displaying a navigation route and a map.
Generally, before receiving a start coordinate and an end coordinate sent by an APP mobile terminal to a server, the APP mobile terminal firstly locates a current position coordinate according to a preset period and determines the current position coordinate as the start coordinate, then receives the input end coordinate, and finally sends the start coordinate and the end coordinate to the server according to the preset period.

Further, when determining the first weight of the first search unit according to the current road section information, the server determines whether a front road section corresponding to the current road section exists according to the current road section information; if not, calculating the length of the current road section, and determining the length of the current road section as the first weight of the first search unit; if so, calculating the length of the front road section, and calculating the length of the current road section; and finally, summing the length of the front road section and the length of the current road section to generate a first weight of the first search unit.
Further, when the server executes dequeuing operation of the route planning queue based on the first weight value and the second weight value and generates the second search unit, the server first obtains two weight values of each search unit in the route planning queue, then sums the two weight values of each search unit to generate a target weight of each search unit, sorts each search unit based on the target weight of each search unit to generate sorted search units, then sequentially intercepts a preset number of search units from the sorted search units, finally obtains a first weight value of each search unit from the preset number of search units, dequeues the search unit corresponding to the smallest first weight value, and generates the second search unit.
Further, when the server generates the navigation route according to the second search unit, firstly, the second search unit is adopted to inquire the front road section in the search unit deduplication set, and then whether the front road section can be inquired to a road section before the front road section in the search unit deduplication set is judged; and if not, splicing all the inquired road sections to generate a transportation route of the vehicle.
