自动变速器半实物仿真试验台CAN总线接口设计

Design of interface for CAN bus on hardware in the loop test-rig of automatic transmission

在研究自动变速器半实物仿真试验台的基础上,进行了相对应系统的CAN总线接口研究.设计了以Motorola公司16位微处理器MC9S12DP256 B为核心的CAN总线接口电路.并且编制了CAN总线结点软件,设计了CAN总线的协议,并在试验台上实现了CAN结点的相互通讯,为车载CAN总线开发设计奠定了基础.

Based on the research of hardware-in-the-loop test-rig of automatic transmission, the paper studied the corresponding CAN bus interface, designed the CAN bus circuit, which takes the Motorola Corporation 16-bit microprocessors MC9S12DP256 B as the core, programmed the CAN bus node software, designed the CAN bus protocol, and realized the CAN node intercommunication on the test-rig. All those laid the foundation of the developing and designing the car CAN bus.
