【Abstract】 We take nonlinear vehicle dynamic model as the controlled object of the system,use Matlab /Simulink software to have designed a lane-keeping-assist system for driving which is based on Kalman filter algorithm. The Kalman algorithm is employed to evaluate the driving state information of the vehicle,and the driver model consisting of pre-targeting-following driver model,vehicle model and controller is utilised to verify the designed system in means of driver-in-the-loop simulation. Result demonstrates that the designed lane-keeping-assistance system can effectively improve the vehicle lane-following capability.更多还原
