example 1

[0129] Example 1: If image 3 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

[0130] Example 2: If Figure 4 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

[0131] Example 3: If Figure 5In 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.

[0132] 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 adj...

Abstract

The invention discloses a control method for an air conditioning system of an electric automobile. The air conditioning system has a standby state and a working state. In the working state, the air conditioning system has a natural air mode and comprises a draught fan and an air volume adjusting knob; the air volume adjusting knob is provided with an air volume gear, an air volume neutral gear and a draught fan braking gear; and the air volume neutral gear is located between the air volume gear and the draught fan braking gear. In the standby state, when the air volume adjusting knob is rotated to the air volume gear, the draught fan operates so that a natural air mode can be started. In the process that the air conditioning system operates in the natural air mode, when the air volume adjusting knob is rotated to the draught fan braking gear, the draught fan stops operating. According to the control method for the air conditioning system of the electric automobile, a passenger can conveniently and rapidly start and stop the natural air mode through the air volume adjusting knob; and the situation that energy is wasted due to the fact that the passenger incautiously touches the air volume adjusting knob or casually operates the air volume adjusting knob can be avoided by arranging the air volume neutral gear, so that decreasing of the driving mileage is avoided.

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. Contents of the invention [0003] The present application is intended to solve at least one of the problems existing in the prior art. Therefore, the present invention aims to provide a control method of an air-conditioning system of an electric vehicle, according to which the energy consumption can be reduced. [0004] According to the control method of the air-conditioning system of an electric vehicle in an embodiment of the present invention, the air-conditioning system has a standby state and a working state, and the air-conditioning system has a natural wind mode in the working state, and the air-conditioning system ...
