Vehicle air conditioner control method and control method thereof

Abstract

The invention provides an auto air-conditioner control system and a control method thereof, and aims to satisfy the requirements of security and comfort. The system comprises an air-conditioner control unit. The air-conditioner control unit receives signals from an internal temperature sensor, a sunlight sensor, an external temperature sensor, an air quality sensor and an evaporator temperature sensor and sends control commands to control the work of an electric velocity modulation module, a blower, an internal and external throttle actuator, a mixture throttle actuator, a pattern throttle actuator and a defrosting throttle actuator, especially the air-conditioner control unit is connected with a front body electronic control system and an engine electronic injection control system through a CAN bus; and the air-conditioner control unit adjusts the work of the air condition system through the state information of the front body electronic control system and the engine electronic injection control system. The system optimizes circuit design, simplifies the operation procedure, satisfies the comfort requirement of a driver, and improves maintenance convenience and the reliability and safety of the system.

Description

technical field [0001] The invention relates to the field of automotive electronic system control, in particular to the automotive air-conditioning control system. Background technique [0002] With the rapid development of automobile electronic and electrical technology, people have higher and higher requirements for the safety and comfort of automobiles. As far as modern cars are concerned, the air conditioner is usually evaluated from the following indicators: temperature index, humidity index, air freshness, defrosting function, and ease of operation. At present, the air-conditioning control system in the automobile circuit can only meet the functional requirements for air conditioning such as temperature adjustment, dehumidification, ventilation, filtration, and defrosting. Usually, all functions are adjusted through the knobs on the automobile air-conditioning control panel. This control method requires driving. Drivers often look down at the air-conditioning control ...
