基于FPGA的汽车空调智能温控系统的设计

long with the development of automobile industry and the microelectronic technology, there are more and more requirements about the performance of automobile air-conditioning system. This article first analyzes the main parameter of the automobile air-conditioning in view of the human body’s comfortable requests on the compartment air and then put forward an intelligent hierarchical control concept, which includes two control levels namely entire vehicle air conditioning control and multiple temperature zones distribution control. As a result, it presents a simulation intelligent system which employs FPGA and DS18B20.to control the automobile air-conditioning temperature. An experimental stage is constructed based on FPGA of Xilinx lnc on which both hardware and software are tested and proved to be correct. The experimental data indicate that the control property is satisfactory and the system performs reliably. This experimental system provides with a solution scheme for the applications of FPGA on automobile industry
