碩士 === 國立交通大學 === 電控工程研究所 === 101 === Research of electric vehicle attracts attention of people nowadays. With the increasing of automotive electronic control units, the data type and quantity of communications units are also growing up. In order to achieve a higher speed and real-time actuation between important components, a high-speed and secure network protocol is needed, and hence the FlexRay vehicle network protocol was developed. Although the FlexRay satisfies high-speed requirement, however it cannot completely replace the low-speed part of the network in the automotive. The main reason behind this is that for electric vehicles, a hybrid network protocol is always a better solution than individual network for electric vehicles due to cost. It is also known that a powerful controller is needed to achieve multiple network protocols integration. Therefore, multicore technology should be used to automotive electronic control units design. In this study, we focus on applying the FlexRay protocol to analyze the network system and achieving internal communications by using multicore technology. To solve message delay problems and to integrate CAN network protocol, a planning network system is proposed based on multicore conception. In the sequel, a more reliable drive-by-wire vehicle with hybrid network system is designed.
