    Specification of CAN Transceiver Driver AUTOSAR CP R20-11 CAN收发器驱动器规范 1 Introduction 1 Introduction This specification describes the functionality, APIs and configuration of CAN Trans- ceiver Driver module. The CAN Transceiver Driver module is responsible for handling the CAN transceiver hardware chips on an ECU. The CAN Transceiver is a hardware device, which adapts the signal levels that are used on the CAN bus to the logical (digital) signal levels recognised by a microcon- troller. In addition, the transceivers are able to detect electrical malfunctions like wiring is- sues, ground offsets or transmission of long dominant signals. Depending on the in- terfacing with the microcontroller, they flag the detected error summarized by a single port pin or very detailed by SPI. Some transceivers support power supply control and wake up via the CAN bus. Dif- ferent wake up/sleep and power supply concepts are usual on the market. Within the automotive environment, there are mainly three different CAN bus physics used. These are ISO11898 for high-speed CAN (up to 1Mbits/s), ISO11519 for low- speed CAN (up to 125Kbits/s) and SAE J2411 for single-wire CAN. Latest developments include System Basis Chips (SBCs) where power supply con- trol and advanced watchdogs are implemented in addition to CAN. These are en- closed in one housing and controlled through single interface (e.g. via SPI). 本规范描述了CAN收发器驱动模块的功能、API和配置。CAN收发器驱动模块负责处理E CU上的CAN收发器硬件芯片。CAN收发器是一种硬件设备，它将CAN总线上使用的信 号电平调整为微控制器识别的逻辑（数字）信号电平。此外，收发器还能够检测电气故 障，例如布线问题、接地偏移或长主导信号的传输。根据与微控制器的接口，它们会标 记检测到的错误，该错误由单个端口引脚汇总或由SPI详细记录。一些收发器支持电源 控制并通过CAN总线唤醒。市场上常见不同的唤醒睡眠和电源概念。在汽车环境中，主 要使用三种不同的CAN总线物理结构。它们是适用于高速CAN（高达1Mbits）的ISO11 898、适用于低速CAN（高达125Kbits）的ISO11519和适用于单线CAN的SAEJ2411。 最新的开发成果包括系统基础芯片(SBC)，其中除了CAN之外还实现了电源控制和高级 看门狗。它们封装在一个外壳中，并通过单一接口（例如通过SPI）进行控制。 8 of 84 Document ID 71: AUTOSAR_SWS_CANTransceiverDriver 8 of 84 文档ID71：AUTOSAR_SWS_CANTransceiverDriver 趣卡翻译（fanyi.qukaa.com）
