The automotive manufacturers today have to put more products faster to the market using shorter vehicle development time and also face significant challenges in vehicle design optimisation due to trade-offs mainly caused by increased focus on fuel economy and CO2 reduction. The market expectation on vehicle acoustics refinement is also increasing and plays a significant role in terms of product perception. With extensive introduction of enablers for improved fuel economy, like automated combustion engine stop/start system as well as down speeding/sizing and more aggressive shift maps for automatic transmissions, additional requirements and development tasks are needed for the noise and vibration (N&V) integration of a driveline. The scope of this paper describes the application of transfer path analysis techniques for low frequency driveline excitation at different low engine speed driving conditions focusing on engine start-up/shut-down events.
