What is Design and Analysis of an Automated Lane Keeping Controller using MATLAB Simulink | MATLAB Solutions?
Design and Analysis of an Automated Lane Keeping Controller using MATLAB Simulink | MATLAB Solutions is a MATLAB-based technical project and simulation model. An Automated Lane Keeping Controller (LKC) is a key component of Advanced Driver Assistance Systems (ADAS) that helps a vehicle maintain its position within a lane by automatically controlling the steering angle. This project presents the design and analysis of an automated lane keeping controller using MATLAB/Simulink. A mathematical vehicle model based on lateral dynamics is developed, and a feedback control strategy is implemented to minimize lane deviation and heading error. The controller performance is evaluated under different driving scenarios such as curved roads and external disturbances. Simulation results demonstrate that the proposed controller effectively reduces lateral error and ensures stable lane tracking, making it suitable for autonomous and semi-autonomous vehicle applications.
