Abstract
ECU procedure likes car’s brain that controls the power source of motor vehicles heart-engine, controls the vehicle chassis, controls all doors ,controls of all instrument panels, and controls the entire vehicle's every move. The entire vehicle control is divided into modules. Effective and accurate control of the entire vehicle needs efficiently, real-time communication between the various modules. CAN bus meet these requirements.
At present, China's automotive electronic industry is still relatively backward. An urgent need is to improve automotive electronic industry research and investment.
In this paper, the ECU procedural framework, the typical design and how ECU controls the entire engine are discussed. The mainly study and application is CAN bus. This paper introduces the history and development of CAN bus technology. And then this paper introduces a CAN module. Because CAN bus is fast, there is the project-- design and implementation of programming of ECU procedure through the CAN bus . This is CAN Bus’s application. One microcontroller communicates with other microcontroller depending on CAN modules. This includes the serial communication and Flash programming.
