随着汽车电子和网络的发展,汽车空调的控制也向人性化,自动化和网络化发展;文中介绍了一种基于CAN总线的汽车空调的自动控制器的设计;该系统由32位单片机构成,主要包括有模拟信号输入模块,信号处理模块,驱动模块,CAN通信模块和在线编程调试模块;控制器可以根据传感器的信息和ECU的指令,实现自动控制以达到最佳的舒适性要求,也可以实现手动调节,满足不同人的需求,另外还可以与整车控制系统通信;经实验证明,该系统具有较强的抗EMC特性和可靠的系统稳定性。
With the development of automotive electronics and network, the control of automotive air conditioners is also humane, automated and networked development. In this paper, a CAN bus-based design of automatic controller for automotive air conditioners is introduced. The system consists of 32- Mainly includes the analog signal input module, the signal processing module, the drive module, CAN communication module and online programming debugging module; The controller can be based on the sensor information and ECU instructions to achieve automatic control to achieve the best comfort requirements, you can also Achieve manual adjustment to meet the needs of different people, in addition to communicate with the vehicle control system; the experiment proved that the system has strong anti-EMC features and reliable system stability.
