Preview Controller Design for Vehicle Stability With V2V Communication

This paper presents a design method of a preview controller for vehicle stability with vehicle-to-vehicle (V2V) communication. Using V2V communication technology, a driver's steering input of a preceding vehicle is obtained on a following vehicle for preview control. To cope with changes in speed and intervehicle distance in a real situation, a position-based sampling is used. With the position-based sampling data, the time-based preview data are resampled by interpolation. For the controller design, linear vehicle modes describing yaw and roll motions are used. To design a preview controller on the following vehicle with the previewed steering input, a linear optimal preview control methodology is adopted. To validate the preview control with V2V communication in terms of vehicle stability, a simulation is conducted using a vehicle simulation package.
