摘要
介绍了一种基于CAN总线的电动汽车数字控制系统的研究过程。该数字控制系统基于Cygnal公司的C8051F040单片机为控制核心,选用Phliips公司的CAN总线收发器PCA82C250芯片作为CAN控制器和物理层总线之间的接口;数字控制系统嵌入μC/OS-Ⅱ实时操作系统,提高了工作稳定性和可靠性。同时还详细讲述了其硬件结构和软件的设计思路。
The design scheme of a digital control system of electric vehicle based on CAN bus is presented in this paper, the control core of which is based on C8051F040 micro-controller of Cygnal company. The CAN bus transceiver PCA82C250 chip is chosen to be the interface of the CAN controller and the physical layer bus. Embedding the real operation system uC/OS-II, the working stability and reliability of digital control system are improved. This article describes its design idea of the hardware and software in details.
