Abstract
Being an excellent field-bus, CAN bus has increasingly been used in automotive electronic systems. MC9S08DZ60, an MCU of the S08D Series of Freescale company is an 8-bit universal automotive electronics controller with a CAN module. In this paper, the design of automotive electronic control unit is introduced based on the MC9S08DZ60. The hardware structure and software design processes have been shown. This circuit has characteristics of simple, low cost, high reliability and real-time. It has provided a scientific basis for the development of the CAN communication electronic control unit based on a microprocessor.
