VCU-based Troubleshooting and Handling System Test Verification Analysis
Compared with conventional cars,pure electric vehicles have the following three outstanding ad-vantages:zero emission of carbon dioxide and other exhaust gases,low noise and brake energy recovery.More and more electronic devices are applied to pure electric vehicles,resulting in the increasing difficulty of diagno-sing pure electric vehicles.Therefore,there is an urgent need to study the fault diagnosis system of electric vehi-cles.The fault diagnosis and processing system in this paper analyzes the failure modes of the power system of pure electric vehicles in detail,which is a great reference for both the later pure electric vehicle fault repair and the development of new models.In addition,a set of fault diagnosis software logic algorithm based on vehicle controller is established.At the same time,the median value average filtering algorithm is applied to optimize the fault diagnosis conditions of analog data acquisition electronic devices,which makes the fault diagnosis conditions more reasonable and accurate.
