摘要
介绍一种自动变速器CAN总线接口技术的实现。在研究自动变速器半实物仿真试验台的基础上,设计了以Motorola公司16位微处理器MC9S12DP256 B为核心的CAN总线硬件接口电路,采用标准CAN总线的通讯协议,编制了CAN总线结点软件。在试验台上成功实现了CAN结点之间的数据相互通讯,为车载CAN总线开发设计奠定了基础。
A CAN bus interface technic was introduced. Based on the simulation test-rig of automatic transmission, CAN bus hardware circuit was designed, which uses the Motorola Corporation 16-bit microprocessors Mcgs12DP256B as the central processing unit. According to standard CAN bus communication protocol, the CAN bus node software was programmed and designed. The data communication between CAN bus nodes was realized on the test-rig. The foundation technic of the developing and designing the car CAN bus is obtained.
