lkas lane compensation device and method

Abstract

The present invention provides a lane compensation device and method for LKAS, which compensates the lane by judging the lane recognition and misrecognition status of a camera equipped with LKAS, thereby removing the noise of lane information in the case of lane recognition, and preventing lane misrecognition Under the circumstances, it can also make it correctly identify the lane, the device includes: a camera for detecting a lane; a lane compensation logic part, which inputs the lane information detected from the camera, and uses a moving average filter algorithm to convert the In the lane information, multiple lane values ​​input within a certain period of time are averaged to calculate the estimated lane value; and LKAS (Lane Keeping Assistance System), based on the estimated lane value, assists in preventing the vehicle from departing from the lane.

Description

technical field [0001] The present invention relates to a lane compensation device and method of LKAS (Lane Keeping Assistance System), and more specifically relates to compensating lanes by judging the recognition and misrecognition status of a camera equipped with LKAS, thereby removing lanes in the case of lane recognition Information noise; in the case of lane misrecognition, the LKAS lane compensation device and method can also identify the lane in a manner similar to the information of the actual lane. Background technique [0002] Lane Keeping Assist System (LKAS: Lane Keeping Assistance System) is a system that detects lanes through sensors and converts the detected lane position signals into torque values ​​to prevent the vehicle from leaving the lane. [0003] This type of lane keeping assist system uses road information measured by a camera to assist the vehicle in staying in the lane, so it is greatly affected by the accuracy of the camera. [0004] When driving...

AI Technical Summary

Problems solved by technology

[0004] When driving on the road, there are frequent cases where the camera does not recognize or misidentify the lane due to environmental factors such as guardrails, brake marks, two-way lanes, snow, rain, etc., and because of such unrecognized or misidentified lanes, When the LKAS operation malfunctions, it will not only make the driver feel uncomfortable, but also lead to a dangerous situation

[0005] Conventional lane recognition devices use lane width information and noise levels to compensate lanes when estimating lanes. However, since lane widths are not actual road information but arbitrary values, there is a problem of low accuracy.
