Problems solved by technology

[0004] However, this previous control method only calculates the control amount (control degree) through the departure distance and the angle between the self-vehicle and the lane, that is, the deviation angle. The device works sensitively
In addition, when calculating the control amount, the stability of the control performance against disturbances such as crosswinds and road gradients cannot be ensured due to the use of empirical steering torque graphs.
[0005] Although there are proposals to solve the above problems by estimating predictable future vehicle actions or variables and compensating them, it is difficult to improve the control performance due to the complexity of the control algorithm and its sensitivity to camera signal errors

Abstract

The present disclosure relates to a lane keeping assist system for controlling a vehicle on the basis of traveling information and road information of the vehicle when the vehicle begins to leave its lane in order to prevent the vehicle from deviating from its lane, which is a system for assisting the vehicle in keeping the lane by generating multiple target routes each being a path for the vehicle to travel without deviating from the lane, calculating a target yaw rate for each target route, and controls the vehicle according to a target steering angle calculated using the target yaw rate.

Description

technical field [0001] The present invention relates to a lane keeping assist system capable of preventing a driver from unintentionally leaving a lane, and in particular to a design of a target trajectory based on the current driving state of a vehicle, calculating a target yaw rate (yaw rate) according to the target trajectory, and according to A lane keeping assist system and method that can effectively prevent the vehicle from leaving a lane by controlling a steering device of the vehicle based on the target steering angle generated by the target yaw rate. Background technique [0002] The Lane Keeping Assist System (Lane Keeping Assist System: LKAS) refers to preventing the driving vehicle from leaving the lane by controlling the vehicle when it is predicted that the driving vehicle will leave the lane based on the driving information of the driving vehicle and road information. [0003] The LKAS control method invented in the past calculates the distance and angle betw...
