The invention provides a train jump control method, a dynamic testing method and a jump benchmark parking method under an FAM (Full Automatic Mode). The jump control method comprises the following steps: an ATP transmits a jump instruction to an ATO, delays for T1 and then synchronously transmits a direction instruction to the train and the ATO; the train receives the direction instruction, then finishes jump preparation and transmits an effective feedback of the direction instruction to the ATO; the ATO receives the direction instruction and the effective feedback, delays for T2 and transmits a traction instruction to a train traction system; the ATO delays for T3, then transmits an instruction carrying a preset traction level to the train traction system, enables the train traction system to output a traction force and enables the train to jump; after jump distance reaches preset distance, the traction instruction is ineffective, and the traction level returns to zero; the ATO delays for T4, then transmits a braking instruction carrying a preset braking level to a train braking system, enables the train braking system to output a braking force, and enables the train to slow down and stably stop; after the train stably stops, the ATO delays for T5, then transmits jump finishing information to the ATP, and enables the ATP to determine the finishing of the jump. Based on the jump control method of the train, a dynamic testing result is more accurate, and jump benchmark parking is more precise.
