标准摘要
[中文适用范围]： 本标准规定了FlexRay通信系统的电气物理层。FlexRay的电气物理层设计用于时间触发网络，数据速率高达10 Mbit/s，用于连接汽车电子控制单元（ECU）。所使用的介质是双绞线。总线上的信号通过在这两根导线之间施加差动电压来实现。拓扑结构的变化范围从点对点连接、线性无源总线和无源星型到主动星型拓扑。本标准包括对传输本身电气特性的定义，以及总线驱动器（BD）和主动星型（AS）设备基本功能的文档。 [外文原描述]： ISO 17458-4:2013 specifies the electrical physical layer for FlexRay communications systems. The electrical physical layer for FlexRay is designed for time-triggered networks with data-rates up to 10 Mbit/s to connect automotive electronic control units (ECUs). The medium that is used is dual wires. Signalling on the bus is accomplished by asserting a differential voltage between those wires. Topology variations range from point-to-point connections via linear passive busses and passive stars up to active star topologies. ISO 17458-4:2013 includes the definition of electrical characteristics of the transmission itself and also documentation of basic functionality for bus driver (BD) and active star (AS) devices.
