The invention discloses a control method for controlling a defrosting heating device. The control method comprises the steps of first of all, detecting whether a defrosting instruction is input, detecting the environment temperature after the input of the defrosting instruction is confirmed, when the temperature environment is greater than a first preset temperature, detecting the outlet temperature of cooling water and the air outlet temperature of a defrosting duct, and when the outlet temperature is less than or equal to a second preset temperature and the air outlet temperature is less than or equal to the first preset temperature, enabling the defrosting heating device to be at the second-gear working condition; and when the outlet temperature and the air outlet temperature are both greater than or equal to a third preset temperature, enabling the defrosting heating device to be at the first-gear working condition, and when the outlet temperature is greater than or equal to a fourth preset temperature and the air outlet temperature is greater than or equal to a fifth preset temperature, enabling the defrosting heating device not to work. By adopting the control method, the defrosting requirement of a windshield can be met, and the defrosting time is shortened. The invention also provides a system employing the control method, and the defrosting heating device.
