Abstract: For the starting noise problem of a hybrid vehicle,first,the location of the problem is determined through subjective and objective evaluation and analysis methods.Secondly,the key factors were analyzed by combining the rattling mechanism.Then,a power simulation model of the drivetrain of the vehicle was established,and engineering control factors were proposed based on the simulation results,which finally led to the successful solution of the starting noise problem.At present,there are fewer st... More
