Problems solved by technology

[0004] In the process of road matching and navigation using GPS navigators, on the one hand, due to the GPS signals often have some errors or interference, the existing navigators are often unable to distinguish adjacent and parallel main and auxiliary roads, resulting in inability to accurately match them as their carrier The road where the vehicle (commonly known as: the current vehicle) is located, which in turn affects the accuracy and real-time performance of the navigation (that is, the existing navigator cannot accurately determine whether the current vehicle is on the main road in real time, or whether the current vehicle has left the main road. and enter the side road to be turned)

Embodiment 1

[0020] Such as figure 1 , the navigator of the present embodiment comprises: a CPU, a touch display screen connected to the CPU, a GPS unit connected to the CPU, a program database connected to the CPU, a camera connected to the CPU, and a map connected to the CPU database. The road path information is stored in the map database, and the road path information includes the attributes of each road section, which includes information such as whether the corresponding road section is a main road or an auxiliary road, and whether the main road and the auxiliary road are adjacent.

[0021] The working methods of the above-mentioned navigator include:

[0022] If the current vehicle is on a main road, and there is an exit leading to the side road on the right side of the main road within 2Km ahead of the current vehicle, the CPU of the navigator obtains the driving on the main road in real time through the camera arranged at the rear of the current vehicle road image to determine w...

Embodiment 2

[0027] On the basis of Embodiment 1, the navigator of this embodiment also includes: a turn signal lever sensor connected to the CPU, the turn signal lever sensor adopts a magnetic induction switch or a toggle switch connected to the CPU for detecting Whether the turn signal lever of the current vehicle is in zero position, left turn position or right turn position.

[0028] On the basis of embodiment 1, the matching method of the road main and auxiliary roads of the navigator of the present embodiment has the following variants:

[0029] The working method of the navigator of the present embodiment includes: if the current vehicle is on a main road, and there is an exit leading to an auxiliary road on the right side of the main road within 2Km ahead of the current vehicle, the CPU of the navigator passes through the The camera at the rear acquires the lane image on the main road in real time to determine whether the current vehicle is in the rightmost lane of the main road; i...

Embodiment 3

[0031]The matching method of the main and auxiliary roads of the navigator in this embodiment includes: if the current vehicle is on an auxiliary road, and there is a main road adjacent to the auxiliary road, and there is a road leading to the left side of the auxiliary road within 1.5Km ahead of the current vehicle. the entrance of the main road, then the CPU of the navigator obtains the lane image of the side road in real time through the camera arranged at the rear of the current vehicle to judge whether the current vehicle is in the leftmost lane of the side road; if the current vehicle In the leftmost lane of the auxiliary road, when the entrance (generally within 30 to 40m from the exit) is about to be reached, it is judged in real time whether the lane line in the image is deflected counterclockwise, if If the lane line deflects counterclockwise, the CPU judges that the current vehicle has entered the main road; the navigator matches the current driving path to the main ...

Abstract

The invention relates to a method for matching main and side roads by a navigator with high real-time performance. The method comprises the following steps: obtaining image of a traffic lane of a side road by virtue of a camera which is arranged at the rear part of the current vehicle by a CPU of the navigator if the current vehicle runs on a side rod, a main road is adjacent to the side rod and an entrance communicated to the main road on the left side of the side rod is 1.5 Km ahead from of the current vehicle so as to judge whether the current vehicle runs on the traffic lane on the leftmost side of the side road; judging whether the traffic lane line in the image counterclockwise deflects or not if the current vehicle runs on the traffic lane on the leftmost side of the side road and arrives at the entrance soon, and judging the current vehicle enters the main road by the CPU if the traffic lane line counterclockwise deflects; and matching the current driving path with the main road by the navigator.

Description

[0001] This application is a divisional application, the application number of the parent application is: 201210173021.4, the name: the matching method of main and auxiliary roads of roads for navigators, and the application date: 2012-05-30. technical field [0002] The invention relates to the technical field of working methods of navigators, in particular to a method for matching main and auxiliary roads of roads by a navigator according to road lanes. Background technique [0003] Existing urban arterial roads often have main and auxiliary roads, such as the second, third and fourth ring roads in Beijing. The closed ring roads only allow motor vehicles, which are main roads; main roads generally include: elevated roads, expressways, etc. The auxiliary road is outside the closed area, next to the main road, and connected with other fork roads. [0004] In the process of road matching and navigation using GPS navigators, on the one hand, due to the GPS signals often have s...
