The present application discloses a dual-motor vehicle control method and apparatus. The method comprises: when a vehicle is in a warm-up state, controlling the vehicle to operate in a series mode, acquiring an initial demand power of the engine, and determining whether the initial demand power is greater than or equal to a power value corresponding to a warm-up curve of the engine; on the basis of a determination result being that the initial demand power is greater than or equal to the power value corresponding to the warm-up curve of the engine, controlling the engine to output a first target power, and controlling the battery to output a limit target discharge power, the first target power being a difference between the initial demand power and the limit target discharge power; on the basis of the determination result being that the initial demand power is less than the power value corresponding to the warm-up curve of the engine, controlling the engine to output a second target power, and outputting a li
