Research on driverless truck PLATOON control based on improved variable time headway policy

To look for the impact of road adhesion coefficient on the safe distance of unmanned trucks while truck platoon driving, the truck platoon control model based on improving variable time headway was designed taking the longitudinal speed of the vehicle and the road adhesion coefficient as variables. A scene was set according to the actual situation of the East China Sea Bridge and a simulation was carried out by TruckSim simulation platform. The results show that compared with the traditional variable time headway policies, this policy can effectively shorten the following distance between unmanned trucks, ensure safe driving and reduce carbon emissions.
