=∑ Distancei·RSi, DistanceiFor the predicted travel distance that number is between the target location of i and vehicle；
Wherein, the distance weighting value not only predicted travel distance dependent between target location and vehicle, but also and mesh
The road conditions marked between place and vehicle are related, can pass through DWi=∑ Distancei·RSiObtain the gas station pair that number is i
The distance weighting value answered.
S206: the driving range LD of vehicle is calculated according to Fuel Oil Remaining；
It is understood that can calculate in conjunction with the energy consumption of vehicle can travel under the premise of known Fuel Oil Remaining
Distance LD, driving range LD are exactly the maximum distance that vehicle can travel.Embodiment as one preferred, it is known can
Under the premise of operating range LD, the gas station that the distance apart from vehicle is greater than driving range LD can be excluded in advance.
S207: the navigation weight value of each target location is calculated using navigation weight calculation formula；Wherein, navigation weight meter
Calculation formula is AOPrivityi=(LD-DWi)·OSi, AOPrivityiThe corresponding navigation weight of target location for being i for number
Value.
S208: all target locations are ranked up to obtain destination column according to the sequence of navigation weight value from high to low
Table；
S209: after determining selected objective target place from communication identifier list, the corresponding navigation road in selected objective target place is generated
Line.
It is understood that the present embodiment can be used for the navigation of other target locations, as parking ground navigation, maintenace point are led
Boat etc..
Illustrate the process of above-described embodiment description below by embodiment in practical applications.
A RSU (drive test unit) is bound by the first step, each gas station, dynamically can constantly transmit the oiling of the gas station
It stands multidate information, includes which gasoline types, queuing vehicle etc..RSU also passes through V2I technology simultaneously can send out to surrounding vehicles
Send fuel station information.
When second step, car owner refuel if necessary, it can be issued and be requested by V2N technology, and by self-position and required vapour
Oil type uploads
After third step, cloud server receive request, it can be believed according to the gas stations met the requirements all near location finding
It ceases (being mentioned in the first step), and information is handed down to the mobile unit of vehicle.
4th step, mobile unit can combine distance, vehicle body Fuel Oil Remaining, gas station's queueing message, road by local computing
Condition information is weighted, and is ranked up to all gas stations.
