The invention discloses an automobile warming control method of an automobile engine, wherein the engine comprises an EGR valve and an EGR cooler, and the EGR valve is located between the EGR cooler and a vent pipe of the engine. The method comprises the steps that engine warming calibration values corresponding to each parameter which respectively stand for an engine working condition, an engine state and an environment state are stored; each of the current parameters which respectively stand for the engine working condition, the engine state and the environment state under a current state is obtained; a precondition of engine warning is that each of the current parameters is less than the corresponding engine warming calibration values, and an opening degree of the EGR valve is adjusted according to the current engine working condition in order to realize the engine warming; and the engine warming is completed when a current engine temperature exceeds a preset engine temperature. The method realizes the quick engine warming by an EGR system installed in the engine and will not influence parts and normal work of the engine during the engine warming. The invention also discloses an automobile warming control device of the automobile engine and the automobile engine with the device.
