| For the abnormal noise caused by vehicle control parameters, a kind of analysis method based on synchronous acquisition of vehicle control parameters and NVH data is introduced. Through the adoption of the double conversion method for protocol and data format, it has realized the synchronous data acquisition of the vehicle/engine control parameters and NVH testing data to complete the control parameters and NVH signal correlation analysis of time domain. The cause of NVH problem can be quickly and accurately located. Through the chassis impact abnormal sound, turbine airflow abnormal sound, vehicle shift jitter three cases. The practical application of vehicle control parameters synchronous acquisition in engineering is introduced. Quickly and accurately identify the cause of abnormal sound, Verification of optimization results was completed. The paper provides a new method and idea for the cause and control of abnormal sound. |
