Summary: | 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.
