Problems solved by technology

[0010] Assume that the user vehicle 101 enters the intersection C1 along lane B, and turns left according to the prompt of the optimal guidance route. At this time, if the user chooses to leave the intersection C1 along the lane E corresponding to lane B, it may be due to C1 and C2 The distance is too close, and the user has no time to change to lane D before reaching C2, but can only drive along lane E; or, due to traffic jam or other reasons, lane D is already full of vehicles, the user's vehicle 101 cannot drive at C1 Enter lane D, but can only drive along lane E or F, so that the vehicle cannot make a left turn at C2 and enter road R1, which deviates from the optimal guidance route

Abstract

The invention discloses an automobile navigation processing method, comprising: according to the prior position of an automobile, selecting a target guide point in a guide lane, while the lane guide information of the target guide point comprises the information of at least two lanes accessing into the guide point; judging if there is other guide points exist in an appointed distance from the target guide point, if there is, extracting the guide point nearest to the target guide point as a correlative guide point; reading the lane guide information of the target guide point and the correlative guide point; generating lane guide information according to preset laws. The automobile navigation processing method can provide accurate lane guide information, avoid users deviating guide lanes and provide good application feel for users.

Description

technical field [0001] The invention relates to the field of vehicle navigation, in particular to a vehicle navigation processing method, a vehicle navigation processing device and a vehicle navigation system. Background technique [0002] With the development of urban traffic network and the improvement of people's living standards, the vehicle navigation system based on mobile positioning and wireless Internet technology has become an indispensable part of people's life. [0003] The current vehicle navigation system is characterized by installing an on-board computer host on the vehicle, using GPS (Global Positioning System, Global Positioning System) combined with inertial navigation equipment as positioning equipment, and connecting display equipment or audio equipment. Under the action of GPS satellites and inertial navigation equipment, this vehicle navigation system can accurately locate the position of the vehicle, including which road the vehicle is on, the speed o...
