Vehicle air conditioner control method, control device and vehicle

Abstract

The invention provides a controlling method and device for a vehicle-mounted air conditioner and the vehicle. The controlling method comprises the following steps that the terminal voltage of an air blower is determined according to air volume gear chosen by a user; the frequency range of a driving signal of an air door is determined according to the terminal voltage of the air blower, wherein thegreater the terminal voltage of the air blower, the smaller the frequency range of the driving signal of the air door; a driving motor of the air door is controlled according to the determined driving signal of the air door, so that the opening degree of the air door is adjusted to the target opening degree. According to the controlling method, the driving motor of the air door can be controlledaccording to the air volume gear, not only is the control precision of the motor improved, safety and reliability of the motor are better guaranteed, but also the controlling accuracy of the air dooris improved, so that running of the air condition is more user-friendly and intelligent, the performance of the air conditioner is improved accordingly, and user comfortable sensation is improved.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a control method, a control device and a vehicle of a vehicle air conditioner. Background technique [0002] In related technologies, vehicle-mounted air conditioners generally have three basic air outlets: surface blowing, foot blowing, and defrosting, and are adjusted through the mode damper, and the temperature has cooling and heating, and is adjusted through the heating and cooling damper, and to ensure fresh air in the car. , with basic functions such as internal and external circulation and air volume adjustment, so as to meet the comfort needs of users. [0003] However, there are certain deficiencies in the related technology, for example, the quality of the air cannot be effectively improved, and due to the need to perform air volume compensation and correction on the air conditioner's mode actuator, heating and cooling actuator, and internal and external circulation...

AI Technical Summary

Problems solved by technology

[0003] However, there are certain defects in the related technology, for example, the quality of the air cannot be effectively improved, and due to the need to perform air volume compensation and correction on the air conditioner's mode actuator, cooling and heating actuator, and internal and external circulation, the related technology only uses limited parameters (For example, the temperature outside the vehicle, the temperature inside the vehicle, and the air volume of the blower) are compensated and corrected, resulting in the inability to meet the user's sensory needs, and the control of the damper mode is chaotic. For example, the load of the damper drive motor is different when the air volume is different, which may easily lead to the damper drive motor. Or stalled, and when controlling the damper drive motor, it is easy to fail to reach the target position, reducing the user's comfort
