Air conditioner control box and system control method thereof

Abstract

The invention discloses an air conditioner control box, which includes a power supply module, an MCU micro control unit, a signal access module, a communication module and a drive module, the power supply module provides power management for the MCU micro control unit, and the signal access module and The input end of the MCU micro-control unit is connected, the drive module is connected with the output end of the MCU micro-control unit, the communication module is connected with the communication end of the MCU micro-control unit, and the software operation of the MCU micro-control unit passes the state machine, and adopts the AUTOSAR architecture, the AUTOSAR architecture includes a basic software layer, an environment variable transmission layer and an application layer, and the application layer is set by the user. The invention separates the control part of the air conditioning control system from the operation panel, can adapt to various types of panels with communication functions or multimedia touch screens, can fully meet the needs of consumers, and can be used across platforms and models to form scale effects and reduce costs .

Description

Technical field [0001] The invention relates to the technical field of air conditioning control for automobiles, in particular to an air conditioning control box and a system control method thereof. Background technique [0002] As an automotive electronic product, automobile air conditioning control box has relatively high requirements for reliability, error handling, and intelligent diagnosis. It collects sensor information and bus control information to control the air conditioning body assembly, compressor, blower and other actuators to achieve temperature Adjustment, air volume control, and panel display are also standard configurations of the center console. Nowadays, most of the controllers on the market are panel + driver board integrated controllers. The advantages of this method are low cost but the disadvantages are also obvious. There are many product types, short life cycles, poor versatility, and long development cycles. It is difficult to form a platform. Moreover...

Problems solved by technology

Currently, most of the controllers on the market are panel + driver board integrated controllers. The advantages of this method are low cost, but the disadvantages are also obvious. There are many types of products, short life cycle, poor versatility, and long development cycle. It is difficult to form a platform.

Moreover, with the development of automotive electronics technology and consumers' increasingly discerning vision, the requirements for panels are gradually changing, and the current integrated controllers are difficult to meet the needs of consumers.
