Embodiment Construction
[0038] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0039] combine figure 1 As shown, the present invention provides a control method for controlling a defrosting heating device, comprising the following steps:
[0040] S11: Detect whether a defrosting command is input, if yes, go to step S12; if not, go to step S13;
[0041] S12: Detect the ambient temperature in real time, and enter step S14;
[0042] S13: the defrosting heating device does not work, and returns to step S11;
[0043] S14: Determine whether the ambient temperature is greater than the first preset temperature, if the ambient temperature is greater than the first preset temperature, go to step S15, if the ambient temperature is less than or equal to the first preset temperature, then Go to step S16;
[0044] S15: the defrosting...

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.
Description
technical field [0001] The invention relates to the technical field of automobile defrosting, in particular to a control method of a defrosting heating device. The present invention also relates to a system applying the above control method, and the defrosting heating device. Background technique [0002] Due to the low ambient temperature in winter and the large temperature difference between the cab and the outside, the windshield of the car is easy to frost. To solve the above problems, the existing defrosting scheme is: the front windshield and the glass on both sides are heated by engine cooling water. For defrosting, the rear windshield uses electric heating wires to defrost. [0003] However, for the defrosting of the front windshield and the glass on both sides, the cooling water of the engine is used to defrost. Frost waits longer. Contents of the invention [0004] The invention provides a control method for controlling a defrosting heating device, which can i...
