Abstract


AMT intelligent shift control is the direction of the development and study of automatic transmission today , how to obtain reliable information about the vehicle is the key to its realization . CAN bus as a serial bus , has a simple structure , real-time , high reliability , and maturity of the technology has been widely applied in the field of foreign auto control . In this thesis, the main work is the CAN bus AMT system . The paper first reviewed the automotive automatic transmission and AMT principle , and then introduced the AMT system its based MC9Sl2C32 microcontroller of TCU , input channels and drive circuit design, its minimum system engineering design , the AMT shift law discussed . The focus of this paper is based on the design and analysis of the application of the AMT TCU CAN bus interface object . The paper compares the fully introduced the works of CAN , CAN bus interface . CAN bus in the car one of the most widely used fieldbus vehicle communication module design based on high and low speed CAN network using MC9S12DG128 microcontroller as the high and low speed CAN network gateway , enabling AMT and other automotive electrical data communication between the control system . In this paper, a general-purpose modular hardware and software design thinking , complete each module hardware circuit design and software programming , simplifies the system hardware and software development , to ensure that the system control functions , and shorten the development cycle , reduce system cost has laid a good foundation for the AMT developed to achieve .
