Control method and control system for vehicle air conditioner

Abstract

The invention discloses a control method for a vehicle air conditioner. The control method comprises the steps that S1, the demand temperatures of riding areas in a vehicle are detected; S2, whether the demand temperatures of the riding areas are the same or not is compared; if all the demand temperatures are the same, a S3 is conducted; and if at least two of the demand temperatures are different, a S4 is conducted; S3, unified temperature control is conducted on all the riding areas; and S4, unified temperature control is conducted on the riding areas which have the same demand temperature, and independent temperature control is conducted on the riding areas which have different demand temperatures. According to the control method for the vehicle air conditioner, by detecting and comparing the demand temperatures of the different riding areas, the possibility that unified control or independent control is chosen to be conducted when different demands are needed is achieved, and using of users is convenient. The invention further discloses a control system used for implementing the control method. Temperature control of the control system is flexible, and the control system more accords with the demands of the users.

Description

technical field [0001] The present invention relates to the technical field of vehicle control, more specifically, to a control method and control system for vehicle air conditioners. Background technique [0002] Automobile air conditioners provide a comfortable interior temperature for car occupants, but individual needs require different ambient temperatures in different areas of the car, mainly for the main and co-pilot areas to provide different temperature controls. For the automotive air-conditioning system, how to automatically identify the needs of the drivers and occupants for the dual-temperature zone control mode and the single-temperature zone control mode, and automatically switch is the real realization of the dual-temperature zone control of the automotive air conditioner. [0003] In the dual-temperature zone control mode in the prior art, the control program stored in the dual-temperature zone automatic air-conditioning controller performs logical analysis ...

AI Technical Summary

Problems solved by technology

[0005] In addition, in practical applications, automotive air conditioners are not always controlled by dual temperature zones, and in some cases, single temperature zone control is also required. The existing technology requires a specific manual operation for switching between the dual temperature zone control mode and the single temperature zone control mode. This brings great inconvenience to the passengers
