[0021] The invention provides a method for controlling an automobile air conditioner. The car air conditioner may specifically be an overhead car air conditioner.

[0022] figure 1 It is a schematic diagram of an embodiment of an automobile air conditioning control method provided by the present invention.

[0023] Such as figure 1 As shown, according to an embodiment of the present invention, the automobile air conditioning control method includes at least step S110 and step S120.

[0024] Step S110: Acquire the current ambient temperature outside the vehicle and the current cumulative heating operation time of the air conditioner.

[0025] Specifically, after the air conditioning unit starts heating operation, the current ambient temperature outside the vehicle and the current heating cumulative operation time of the air conditioner are detected. Wherein, when the air conditioner has not been defrosted after being turned on, the heating cumulative operation time is the time from when the air conditioner is turned on to the current moment, and when the air conditioner has been defrosted after being turned on, The heating cumulative running time is the time from the end of the last defrosting to the current moment.

[0026] Step S120: Determine whether the air outlet and/or air inlet of the air conditioner are covered with ice and snow according to the current ambient temperature outside the vehicle and the current cumulative heating operation time.

[0027] Specifically, according to the current ambient temperature outside the vehicle and the current cumulative heating operation time, it is determined whether the air outlet and/or air inlet of the air conditioner are covered with ice and snow, so as to determine whether the air conditioner needs to be exhausted. The tuyere and/or the wind inlet conduct ice and snow melting operation. Depending on the air conditioning structure, the air intake and/or exhaust may be covered by ice and snow.

[0028] In a specific embodiment, determine the heating cumulative operating time set value corresponding to the current outdoor ambient temperature; determine whether the current heating cumulative operating time is less than or equal to the set value; if so, determine The air outlet and/or the air inlet of the air conditioner are covered with ice and snow; if not, it is determined that the air outlet and/or the air inlet of the air conditioner is not covered by ice and snow.

[0029] Optionally, determining the heating cumulative operating time setting value corresponding to the current ambient temperature outside the vehicle may specifically include: obtaining a corresponding relationship between at least one preset temperature interval and the heating cumulative operating time setting value, and determining The current ambient temperature outside the vehicle belongs to a temperature interval in at least one preset temperature interval, and the set value corresponding to the temperature interval is determined as the heating cumulative operating time set value corresponding to the current ambient temperature outside the vehicle. For example, divide the outer ring into n temperature ranges, X1 represents the T1-T2 temperature range, X2 represents the T2-T3 temperature range,..., Xn represents the Tn-Tn+1 temperature range; the cumulative heating operation time corresponding to the X1 temperature range Set values ​​Y1, X2, corresponding to the heating cumulative operating time setting Y2, ..., Xn temperature range corresponding to the heating cumulative operating time setting Yn.

[0030] According to the above-mentioned embodiments of the present invention, it is possible to accurately determine whether the air outlet and/or the air inlet of the air conditioner are covered with ice and snow according to the current ambient temperature outside the vehicle and the current accumulated heating operation time of the air conditioner, so as to perform the ice and snow melting operation and solve the problem. The air outlet and/or the air inlet are covered with ice and snow, which leads to the problem that the heating effect of the air conditioner decreases.

[0031] Optionally, the foregoing step of acquiring the current outdoor ambient temperature and the current cumulative heating operation time of the air conditioner (step S110), and according to the current outdoor ambient temperature and the current cumulative heating operation time The step of determining whether the air outlet and/or the air inlet of the air conditioner are covered with ice and snow (step S110) may be performed before the air conditioner performs the defrosting operation, or after the air conditioner performs the defrosting operation.

[0033] In step S130, if it is determined that the air outlet and/or the air inlet of the air conditioner are covered with ice and snow, the air outlet and/or the air inlet are melted by controlling the heat dissipation fan of the outside heat exchanger.

[0034] Specifically, if it is determined that the air outlet and/or the air inlet of the air conditioner are covered with ice and snow, the air outlet and/or the air inlet need to be melted. After the air conditioner performs the defrosting operation, pass The heat dissipation fan of the heat exchanger outside the vehicle is controlled to melt the ice and snow on the air outlet and/or the air inlet of the air conditioner.

Preferably, in order to better avoid ice and snow coverage, step S140 may be performed while step S130 is performed, that is, the air outlet and/or air inlet are melted by controlling the heat dissipation fan of the outside heat exchanger. At the same time, an electric heating device is used to assist in melting snow and ice.
