ABSTRACT
This paper presents an active roll preview control with vehicle-to-vehicle (V2V) communication. In intelligent transportation system (ITS) environments, several states and measured signals can be transmitted to following rear vehicle through V2V communication device. The preceding vehicle’s lateral acceleration is sent to the following vehicle. A LQ optimal preview controller for application to active roll control(ARC) is designed using the lateral acceleration. To cope with the speed change of vehicles, a position-based sampling on lateral acceleration is adopted. Based on the data, a distance-based interpolation is performed to resample the time-based lateral acceleration for preview control of ARC. To check the performance of the proposed method, simulation is performed with linear and nonlinear vehicle models.
Key Words: Active roll control, Position-based sampling, Distance-based interpolation, Preview control, V2V communication
