Development of AMT Fault Diagnosis Technique Based on KWP2000 总被引:1,自引:1,他引:0
In order to make automatic mechanical transmission (AMT) capable of performing fault self-diagnoses and adaptive to standard communication interface,through technical analysis and intensive study concerning on-board diagnostic protocols now widely applied in Europe and America,KWP2000 on CAN is accepted as a technological path.An AMT fault communication system using hardware-in-the-loop simulation by dSPACE is developed,and communications compatible with ISO 15031-6 is realized on this module.Moreover,a han... 相似文献

AMT-Fault-Diagnosis Device Based on ISO 15765 总被引:1,自引:0,他引:1
To debug automatic mechanical transmission (AMT) more quickly and accurately, an AMT-fault-diagnosis device is designed based on the ISO 15765 protocol, which adopts the flow control mechanism and has off-line diagnostics function. Requirements for the device are analyzed and diagnostic trouble code (DTC) is defined. Electrically controlled hardware with graphics display function and fault diagnostic software flowchart are designed based on the electronic control hydraulic AMT system. Bench and vehicle driving tests showethat the AMT-fault-diagnosis device can read and delete the fault message successfully with a stable performance. 相似文献
