Provided is a relative velocity train protection method and apparatus. The method includes he following steps: a preceding train and a following train in two successive trains calculate their safe spatial-temporal trajectory information in a stopping process using an electronic map, velocity measurement and positioning information, and performance of the train (S11); the following train obtains the spatial-temporal trajectory information of the preceding train through vehicle-to-vehicle communication (S12); the following train creates a safety condition according to a constraint that a position of the following train does not surpass that of the preceding train at any time, and solves the emergency brake intervention (EBI) velocity of the following train (S13); the following train determines whether its measured velocity v2(t0) exceeds the EBI velocity E2(t0), and if so, make the following train decelerate until the following train stops (S14).
