Operating method for air conditioning system for vehicle, and air-intake system thereof, and vehicle

An operating method of an air conditioning system for a vehicle, wherein the air conditioning system comprises a motor, an operating dial, an internal-circulation ventilation door and an external-circulation ventilation door, the motor is fixedly connected to the operating dial, the operating dial is provided with an internal-circulation track and an external-circulation track, the internal-circulation ventilation door and the external-circulation ventilation door are provided with an internal connecting shaft and an external connecting shaft, respectively, the internal connecting shaft and the external connecting shaft are capable of sliding in the internal-circulation track and the external-circulation track, respectively, to drive the internal-circulation ventilation door and the external-circulation ventilation door to rotate, and the operating method of the air conditioning system comprises:

• receiving a pulse signal, wherein the pulse signal comprises a preset direction of rotation and a preset step count of rotation of the motor;
• and
• driving the motor to rotate in the preset direction by the preset step count, to drive the operating dial to rotate, so as to cause the internal-circulation ventilation door to rotate to a first preset angle, and the external-circulation ventilation door to rotate to a second preset angle, so that an air-intake ratio of an internal air-intake volume to an external air-intake volume of the air conditioning system is a preset first ratio;
• wherein in a preset fourth air-conditioning-system operation mode, the air conditioning system operates as:
• the preset direction is a counterclockwise direction, the preset step count is 2440 steps, the internal-circulation ventilation door rotates to the first preset angle of 75°, and the external-circulation ventilation door rotates to the second preset angle of 39°, so that the air-intake ratio of the internal air-intake volume to the external air-intake volume of the air conditioning system is 55:45;
• wherein the method further comprises:
• determining temperature intervals of an outdoor temperature T1, an engine water temperature T2, a preset air-conditioner temperature T3 and an indoor temperature T4, or determining a speed interval of a speed of a vehicle-speed signal V1;
• and
• when the outdoor temperature T1 is within a first preset temperature interval, the engine water temperature T2 is within a second temperature interval, the preset air-conditioner temperature T3 is within a third temperature interval, the speed of the vehicle-speed signal V1 is within a first speed interval, the preset air-conditioner temperature T3 is greater than the indoor temperature T4 by a first preset temperature difference, and an air conditioner is in a heating demand, executing the third air-conditioning-system operation mode, the fourth air-conditioning-system operation mode or the fifth air-conditioning-system operation mode.
