Abstract
The present invention provides a lane following system and method considering a driving assistance lane that can flexibly cope with complex roadway situations and enable lane following to improve the reliability of an LCA system, and furthermore, expand a range of a road to which an autonomous driving system is applied.
Claims12
A lane following system for controlling a steering device of a driving vehicle and responsive to a driving assistance lane formed in a vehicle path, the lane following system comprising:
- an image receiving unit configured to receive front image data of the driving vehicle;
- an image analysis unit configured to input the front image data to a pre-stored network and analyze a feature map for each pixel of the front image data;
- an analysis processing unit configured to extract a lane change driving lane to be followed by the driving vehicle by using a result by the image analysis unit;
- and
- a steering control unit configured to compare a driving line currently followed by the driving vehicle with the lane change driving lane extracted from the analysis processing unit, and, in response, generate a control signal for controlling a steering angle of the vehicle.
A lane following method responsive to a driving assistance lane and performed by a processor, the lane following method comprising:
- an image input step of inputting front image data of a driving vehicle;
- an image analysis step of inputting the front image data to a pre-stored network to analyze feature maps for each pixel;
- a lane change extraction step of applying the result of the image analysis step to a pre-stored analysis algorithm to extract a lane change driving lane to be followed by a driving vehicle;
- a steering control step of comparing a driving lane currently followed by the driving vehicle with the lane change driving lane determined by the lane change extraction step, and, in response, generating a control signal for controlling a steering angle of the vehicle;
- and
- a driving extraction step of analyzing the front image data input by the image input step to extract the driving lane currently followed by the driving vehicle.
