The invention discloses an engine starting method of a hybrid power vehicle power system. The method comprises the following steps: (1) when an engine is in a stop state and a gearbox is in a non-neutral state, and after a motor drives a vehicle to reach the set vehicle speed, a clutch is gradually joined; (2) the clutch is gradually joined to a half joint point, the engine begins to operate; (3) the clutch is continuously and gradually joined from the half joint point to enable the rotating speed of the engine to synchronize with the rotating speed of the motor; and the position of the clutch serves as a synchronization point; and (4) the clutch is continuously and gradually joined totally from the synchronization point; the engine and the motor perform the torque conversion; and the engine drives the vehicle to travel. The method solves the technical problem of reduction of power performance directly caused by a no-power driving state of the vehicle in the starting process because of shifting to a neutral gear in the engine starting process of the hybrid power vehicle power system.
