NVH Testing of Hybrid Electric Powertrains 2001-01-1543
The purpose of his paper is to further the understanding of NVH test techniques for hybrid electric powertrains. It addresses dynamometer testing specifically. Due to the nature of the hybrid electric function, which includes situations when the engine is not running as well as different ratios of torque for power component combinations, typical testing methods are not adequate. Hybrid electric testing requires unique test conditions, dyno control, instrumentation and analysis. This paper attempts to establish some test standards directed specifically to the data needs of hybrid electric power trains.
