Vehicle lateral control system having lane model with modulation weighting and control method thereof

A vehicle lateral control system having a lane model with modulation weighting for controlling a vehicle, the vehicle lateral control system comprising:

• a camera disposed on the vehicle and faced toward a front of the vehicle, wherein the camera is configured to capture a front image of the vehicle to generate a front image dataset;
• an image processing device signally connected to the camera and receives the front image dataset, wherein the front image dataset is analyzed by the image processing device to obtain a plurality of lane markers, and the image processing device establishes a lane fitting curve according to the lane markers and a target weighting;
• a controller signally connected to the image processing device and having a plurality of vehicle dynamic parameters and a target distance, wherein the target weighting is changeable according to the target distance, and the controller generates a steering control weighting according to the lane fitting curve and the vehicle dynamic parameters;
• and
• a steering device signally connected to the controller and disposed on the vehicle, wherein the steering device is configured to control a turning direction of the vehicle according to the steering control weighting.
