The transfer function from crankshaft torque to acceleration at steering wheel and driver seat is calculated using finite element model of vehicle. Meanwhile the output torque of engine at idling condition is meas-ured by test. Thus the idle vibration of vehicle can be well predicted and controlled with A/T model at early phase of vehicle development. Finally the applicability and accuracy of the method in vehicle performance design are veri-fied by analysis and test.
