Abstract: An eco-CACC controller is established to realize cooperative adaptive cruising with enhanced fuel efficiency on rolling terrain. It has the following features: i) with better performance on rolling terrain; ii) with enhanced fuel-saving benefits; iii) ready for real-time implementation while guaranteeing optimality; iv) enabling transportation with mobility and ecology improvement. The performance of the proposed eco-CACC controller was evaluated. The influence of different road types on the performance was analyzed. Experiment results showed that applying the proposed system can improve fuel economy while guaranteeing the effectiveness of platooning. The average fuel saving is about 44.75% at collector road and about 27.18% at major arterial compared to a traditional CACC controller.
