基于CCP的电控柴油机标定系统开发

Calibration System Development of Electronically-controlled Diesel Based on CAN Calibration Protocol

在分析研究CCP的基础上,开发了基于CCP的电控柴油机标定系统平台,实现了标定系统与ECU之间准确、可靠的数据通讯。利用存储区映射实现了标定工具对ECU数据的在线修改,大大提高了电控系统匹配、开发效率,最后利用该标定平台在高压共轨电控系统上进行了试验。

An electrically-controlled calibration platform of diesel is introduced based on CCP (CAN Calibration Protocol) after the study of CCP, and reliable, precise communication is created between calibration system and ECU (Electronically Controlled Unit). ECU data is modified on line through memory mapping by calibration tool, so the developing efficiency of electrically-controlled system is improved greatly, and finally an experiment iscarried out on high-pressure common rail system.
