成都盤灃科技汽車電子開發(fā)之二:
繼續(xù)*一講的內(nèi)容,根據(jù)汽車電子整車網(wǎng)絡(luò)開發(fā)流程*一步網(wǎng)絡(luò)規(guī)定與協(xié)議制定,我們應(yīng)該如果建立的一套完整CAN網(wǎng)絡(luò)通信規(guī)則和協(xié)議呢?
首先,我們應(yīng)該要學(xué)習(xí)如下汽車行業(yè)規(guī)范。
1、CAN總線通信標(biāo)準(zhǔn):
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總線診斷標(biāo)準(zhǔn):
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總線應(yīng)用層:
具體的請參考就J1939相關(guān)協(xié)議,根據(jù)具體的車型,是由主機廠采用相關(guān)修改具體協(xié)議來設(shè)計。
明天我們將會,根據(jù)具體的協(xié)議內(nèi)容作參考案例講解。
