example 1

[0152] Example 1: If Figure 13 In the standby state or in the natural wind mode, when the temperature adjustment knob is turned right by one gear, the expected effect is to adjust the system to the heating mode of +1 heating level, but because the heating is not pressed Activator, the operation judgment is invalid, and the system still maintains the state of natural air supply. Then, when the temperature adjustment knob is turned left by one gear, the expected effect is to turn off the heating mode of the +1 heating level of the system, and the system still maintains the state of natural air supply. This design is intended to avoid the waste of energy caused by passengers operating the temperature control parts too casually, thereby avoiding the reduction of driving mileage.

example 2

[0153] Example 2: If Figure 14 In the standby state or in the natural wind mode, when the temperature adjustment knob is turned right by six gears, the expected effect is to adjust the system to the heating mode of the maximum heating level, but because the heating is not pressed Components, the operation judgment is invalid, and the system remains in the state of natural wind supply. Then, when the temperature adjustment knob is turned left to the sixth gear, the expected effect is to turn off the heating mode of the maximum heating level of the system, and the system still maintains the state of natural air supply. This design is intended to avoid the waste of energy caused by passengers operating the temperature control parts too casually, thereby avoiding the reduction of driving mileage.

example 3

[0154] Example 3: If Figure 15 In the standby state or in the natural wind mode, when the temperature adjustment knob is turned rightward to the seventh gear and above, the angle of rotation exceeds the starting gear on the hot air side, the passenger's intention is clear, and the desired effect of the passenger is to adjust the system to Heating mode for maximum heating level. At this time, the operation judgment is valid, and the system starts the heating mode at the maximum heating level. Since the maximum heating level of the system is level 4, the heating level remains at level 4 when the temperature adjustment knob is turned to the left at a small angle, and the heating level decreases when the temperature adjustment knob is turned to the +3 level.

[0155] In addition, in the standby state, when the temperature adjustment knob is turned rightward from 0 to the seventh gear and above, the wind speed is at the third gear; in the natural wind mode, when the temperature a...

Abstract

The invention discloses a control method of an air-conditioning system of an electric automobile. The air-conditioning system comprises a fan and a wind quantity adjusting knob, wherein the wind quantity adjusting knob is provided with a wind quantity gear, a wind quantity neutral gear, and a fan braking gear, and the wind quantity neutral gear is positioned between the wind quantity gear and the fan braking gear. Under a standby condition, when the wind quantity adjusting knob rotates to the wind quantity gear, the fan runs to operate in a natural wind mode; in the process that the natural wind mode is operated, when the wind quantity adjusting knob rotates to the fan braking gear, the fan stops running. According to the control method disclosed by the invention, the natural wind mode can be rapidly opened and closed through the wind quantity adjusting knob; the wind quantity neutral gear is arranged, so that energy waste caused by the careless operation of a passenger can be avoided, and the situation that the driving range is reduced is avoided; and segmental display screens of an air conditioning control panel are cancelled, and the display screen is utilized to show the air conditioner operating information, so that the occupied area of the air conditioning control panel is reduced, and the air conditioning control panel is simple and artistic in structure, and complex in control functions.

Description

technical field [0001] The invention relates to the field of electric vehicles, in particular to a control method for an air conditioning system of the electric vehicle. Background technique [0002] The control method of the air conditioner on the electric vehicle is complicated, which is not conducive to reducing energy consumption and saving energy. [0003] There are many control parts, fragmented small display screens, and control panels that need to be installed on the center console of electric vehicles, and the shapes are different, which will give people a sense of heterogeneity and fragmentation as a whole. For example, the air conditioner control panel will form an irregular shape, and the panel is provided with two or three rows of buttons, keys and two or three small display blocks, etc., which is not conducive to the simple and beautiful design of the interior of the electric vehicle. Contents of the invention [0004] The present application is intended to ...
