The invention provides a train emergency self-walking optimization control method, relates to the technical field of train emergency guidance, comprehensively considers complex constraint conditions such as a bidirectional arrival distance (line condition), a train speed grade, a life support system demand, regenerative braking energy feedback and a vehicle-mounted energy storage system state (train state parameter), and has the advantages of low energy consumption, high reliability and high reliability. The train speed curve is optimized by taking short-time return as an optimization target and taking available power and energy of an energy storage system as constraint conditions, when the train enters an emergency self-walking state, optimization of running time and running energy consumption is considered at the same time, rapid self-rescue of the train is achieved, life safety of passengers is guaranteed, and the problem that the train cannot run quickly during self-walking is solved. The defects of the existing emergency operation scheme in solving the speed curve are overcome, and the rapid self-rescue of the train under the traction network power-free working condition is realized.
