The present application is suitable for the technical field of vehicle controlling, and discloses a method for coordinated control over starting and gear shifting of an engine of a vehicle, an apparatus and a terminal device. The method includes: if a starting type of the vehicle is gear-shifting dynamic starting, controlling a clutch to reduce a torque, the clutch being inside a gearbox, and regulating a speed regulating torque for establishing a slip of a P2 motor, so that an absolute value of a difference between a rotational speed of the P2 motor and a target rotational speed is less than a first preset difference; controlling a rotational speed of the engine to reach a first preset rotational speed, and when the rotational speed of the engine reaches the first preset rotational speed, sending an oil-injection and ignition command to the engine; determining a slip exiting moment, and at the slip exiting moment, controlling the P2 motor to exit from the speed regulating torque, and controlling the clutch inside the gearbox to perform a return-torque action; and controlling the rotational speed of the P2 motor, the rotational speed of the engine and a shaft speed of an input shaft of the gearbox to be synchronous. The present application can effectively solve the problem in the prior art that the rotational speed of the engine is high and the entire-vehicle NVH performance is poor at a low vehicle speed.
