摘　　要：This paper investigates the minimal-energy driving problem for high-speed electric train, and then proposes a three-stage optimal strategy. First, a switching system model is introduced to describe the new dynamics in high-speed electric train, which considers the extended range of speed, the energy efficiency and the regenerative brake. Based on the new model, the optimal driving strategy with minimal-energy consumption is studied, and the problem is boiled down to optimal control for switching systems. Using a numerical algorithm, a three-stage driving strategy is concluded, in which the traditional quasi-coasting stage is discarded and the maximal traction and brake are not suitable anymore. Finally, a case study on CRH is illustrated.This paper investigates the minimal-energy driving problem for high-speed electric train, and then proposes a three-stage optimal strategy.
