混合动力系统故障诊断技术.pdf

第四部分：混合动力第四部分：混合动力OBD的标准的标准DTC清单清单 OBDII standard DTC codes for Hybrid Powertrain 下面是SAE J2012 和 ISO 15031 标准： 混合动力系统的 OBD DTC 完整清单 这些DTC 基本包含了近十几年来已经量产的混合动力车型的所有故障码 注：很多故障码是重复的， 因为要覆盖不用OEM 的不同整车混合动力系统 主机厂混合动力系统HCU的故障码，将是这个DTC 清单里的一个子集 就是说只需要支 持其中的一小部分DTC 即可 具体需要指出哪些故障码， 需要根据汽车主机厂的整车设计和HCU的控制系统功能，来 一一甄别 很多DTC 是需要在BMS 和MCU ， 以及TCU 里支持的 不一定在HCU里做 但是因为汽车主机厂的BMS， MCU， 和TCU 的故障诊断功能本身也不完善；所以很多 DTC可能要在HCU里支持 EON可以在项目开展后， 根据汽车主机厂混合动力系统的特点，来取出下列DTC 的一个 小的子集， 来做HCU的故障诊断开发 同时，汽车主机厂的混合动力系统还有一些最新的系统配置和功能，这些子系统和功能的 故障诊断在现有的DTC清单里，并没有体现。

这部分故障诊断功能， 需要专门定义新的 制造商特有的故障码DTC例如：汽车主机厂混合动力系统里的离合器，是混合动力技 术里一个比较新的设计；在现有的 DTC 清单里没有这个子系统的DTC； 需要专门定义制 造商自有的DTC来处理这个离合器的故障诊断 TABLE D11 - P0AXX HYBRID PROPULSION DTC Number DTC Naming Location Foot Note HCU DTC – 混合动力混合动力控制器控制器DTC 清单清单 HCU 硬线硬线连接的子系统故障：连接的子系统故障： P0A1D Hybrid Powertrain Control Module P0A94 DC/DC Converter Performance P0AB9 Hybrid System Performance P0AC4 Hybrid Powertrain Control Module Requested MIL Illumination P0C2F Internal Control Module Drive Motor/Generator - Engine Speed Sensor Performance U0028 Vehicle Communication Bus A U0029 Vehicle Communication Bus A Performance U0030 Vehicle Communication Bus A (+) Open U0031 Vehicle Communication Bus A (+) Low U0032 Vehicle Communication Bus A (+) High U0033 Vehicle Communication Bus A (-) Open U0034 Vehicle Communication Bus A (-) Low U0035 Vehicle Communication Bus A (-) High U0036 Vehicle Communication Bus A (-) shorted to Bus A (+) U0037 Vehicle Communication Bus B U0038 Vehicle Communication Bus B Performance U0039 Vehicle Communication Bus B (+) Open U0040 Vehicle Communication Bus B (+) Low U0041 Vehicle Communication Bus B (+) High U0042 Vehicle Communication Bus B (-) Open U0043 Vehicle Communication Bus B (-) Low U0044 Vehicle Communication Bus B (-) High U0045 Vehicle Communication Bus B (-) shorted to Bus B (+) 注：黄色DTC 是HCU 应该支持的，但是从目前东风HCU的硬件配置图看，HCU硬件还 不支持。
