A method for intelligent control of engine initiation, comprising following steps: S101: acquiring a current drive mode of a vehicle; S102: determining whether the current drive mode meets a first predetermined drive mode, wherein the first predetermined drive mode is one of a pure electric drive mode or a hybrid drive mode; S103: acquiring current remaining capacity of a battery when the current drive mode meets the first predetermined drive mode; S104: determining whether the current remaining capacity is greater than a first predetermined capacity threshold, wherein the first predetermined capacity threshold is a sum of a capacity value required for starting an engine, a capacity threshold required for heating a catalytic converter by a heating plate and a capacity threshold required for operating the vehicle in the pure electric drive mode; S105: no need to start the engine when the current remaining capacity is greater than the first predetermined capacity threshold; S106: determining whether an operating state of the vehicle meets a predetermined operating state when the current remaining capacity is not greater than the first predetermined capacity threshold, wherein the predetermined operating state is represented as the vehicle being not in an acceleration state or a torque increasing state; S107: acquiring a temperature of the catalytic converter when the operating state of the vehicle meets the predetermined operating state; S108: determining whether the temperature of the catalytic converter is less than a first predetermined temperature threshold; S109: heating the catalytic converter by the heating plate to not less than the first predetermined temperature threshold when the temperature of the catalytic converter is less than the first predetermined temperature threshold; and S1010: starting the engine to rotate forward with fuel cut-off when the temperature of the catalytic converter is not less than the first predetermined temperature threshold.
