Abstract：The platooning of automated vehicles can greatly improve the fuel efficiency of road transportation. Current studies will reduce fuel consumption by using very short car-following distances to reduce the aerodynamic drag on the following vehicles, which increases rear-end collision risks. This paper presents a periodic control method, pulse and glide (PnG) operation, for heterogeneous vehicle platoons to minimize the overall fuel consumption. The switching control method controls each vehicle to maintain the given the inter-vehicle distance while reducing the fuel consumption. Simulations show that this controller can maintain the inter-vehicle distance within a bounded range and reduce fuel consumption by up to 23.3% compared to linear quadratic (LQ) controllers.
