A comprehensive simulation capability is presented for the analysis of vehicular platoons with or without collisions. A separate collision module (CDM) is integrated within the Platoon Simulation Package (PSP) to allow the recognition and dynamic simulation of intra- platoon collisions. Test simulations are presented and an alternative control strategy, one based on H , optimization, is described. This control approach allows an explicit account to be taken unknown disturbances and system variations, i.e. it produces a robust design.
