Embodiment Construction

[0030] As shown in Figure 4, the path planning device with advance turning lane information of the present invention includes:

[0031] Early turning lane information collection module 1 is used to collect the early turning lane information of the actual road;

[0032] road database 2 for storing information about roads;

[0033] The path planning module 3 is used to determine the driving path of the vehicle according to the start point and end point and the advance turning information of the road.

[0034] As shown in Figure 5, the path planning module 3 includes:

[0035] The destination road module 31 is used to find out the road where the destination coordinates are located;

[0036] The starting point road module 32 is used to find out the road where the starting point coordinates are located;

[0037] The shortest path selection module 33 is used to find other roads connected to the road where the starting point coordinates are located, select the road with the shorte...

Abstract

The invention discloses a path programming device with advanced turning lane information, which comprises an advanced turning lane information collecting module, used for collecting the advanced turning lane information of actual road; a road database, used for storing the related information of road; a path programming module, used for fixing the driving track of vehicle according to the initial point, the end point and the advanced turning information. By adopting the path programming device with advanced turning lane information, the invention can make the programmed path clearer and more rational.

Description

technical field [0001] The invention relates to the field of vehicle navigation, in particular to a path planning device with advance turning lane information. Background technique [0002] The early turning lane refers to a special lane used for vehicles to turn right (left) ahead of time and diverge at the intersection. Such lanes are separated from ordinary lanes by physical barriers, zebra crossings (that is: white diagonal solid lines) or solid line barriers. As shown in Figure 1, the oblique line segment is an early right-turn road. [0003] As shown in Figure 2, it is an actual road model. The road at the dotted elliptical frame is used to divert right-turning vehicles (ie: early right-turning lanes), and in the existing path planning device, there is no early-turning road indication, as shown in Fig. 3. Among them, there are only lane lines perpendicular to each other, and there is no oblique line indicating an early right turn. [0004] Therefore, the existing pa...
