MOST150网络及其在车载电控系统中的应用

MOST150 network and its application in vehicle electronic control system

传输通信系统(Media Oriented System Transport,MOST)网络在车载多媒体通信等场合有着广泛的应用,目前针对MOST网络的研究多针对MOST25、MOST50等,而MOST150网络具有带宽高,速率快的优点,适用于车载多媒体通信,但其在车载电控系统中的应用较少。为此,本文针对MOST150网络及其功能特点进行了介绍,提出了MOST150网络及CAN-MOST模块在电动汽车用电池管理系统(Battery Management System,BMS)的应用,并进行实验验证,结果表明加入MOST的电池管理系统抗干扰以及复杂环境下的信号长距离传输能力有较大提升。

Media Oriented System Transport (MOST) networks have been widely used in automotive multimedia communications and other occasions. At present, the research on MOST networks is mainly directed to MOST25 and MOST50. The MOST150 network has the advantages of high bandwidth and high speed, and is applicable to Car multimedia communication, but its application in the vehicle electronic control system is less. Therefore, the MOST150 network and its functional characteristics are introduced, and the application of MOST150 network and CAN-MOST module in Battery Management System (BMS) for electric vehicles are proposed. The experimental verification is also carried out, andthe experimental results show that the BMS based on MOST shows better ability of antielectromagnetic interference and long distance signal transmission in complex environment.
