The invention discloses a control method for preventing a sparking plug from being frozen in winter. In winter, the control method is adopted before parking every time, a parking switch is connected to an electronic control unit (ECU), logic values of a temperature signal and a shift position signal are set in the ECU, logic and operation of two signals are carried out under triggering of the parking switch, and a water steam removing strategy or a direct halt strategy is selected according to the calculation result, so that the phenomenon of a frozen electrode of the sparking plug at a low temperature is avoided, normal smooth start of an engine in a low temperature environment can be guaranteed, and unnecessary expenditure caused by deicing the sparking plug is avoided, and meanwhile, the load to a valve by opening a gas tank valve repeatedly by a driver as the sparking plug is frozen is also avoided, so that the service life of the valve is prolonged.
