成都盘沣科技汽车电子开发之二:
继续*一讲的内容,根据汽车电子整车网络开发流程*一步网络规定与协议制定,我们应该如果建立的一套完整CAN网络通信规则和协议呢?
首先,我们应该要学习如下汽车行业规范。
1、CAN总线通信标准:
ISO 11898-1 Road Vehicle - Controller Area Network (CAN) - Part 1: Data link layerand physical signalling;
ISO 11898-2 Road Vehicle - Controller Area Network (CAN) - Part 2: High-speed medium access unit;
SAE J2284-1 High-Speed CAN (HSC) for Vehicle Applications at 125 KBPS;
SAE J2284-3 High-Speed CAN (HSC) for Vehicle Applications at 500 KBPS。
2、CAN总线诊断标准:
ISO 15765-1 Road vehicles - Diagnostics on Controller Area Networks (CAN) - Part 1:General information;
ISO 15765-2 Road vehicles - Diagnostics on Controller Area Networks (CAN) - Part 2:Network layer services;
ISO 15765-3 Road vehicles - Diagnostics on Controller Area Networks (CAN) - Part 3:Implementation of unified diagnostic services (UDS on CAN);
ISO 14229-1 Road vehicles - Unified diagnostic services (UDS) - Part 1: Specification and requirements;
ISO 15031-6 Road vehicles - Communication between vehicle and external equipment for emission-related diagnostics - Part 6: Diagnostic trouble code definitions。
3、CAN总线应用层:
具体的请参考就J1939相关协议,根据具体的车型,是由主机厂采用相关修改具体协议来设计。
明天我们将会,根据具体的协议内容作参考案例讲解。
