Development of shift comfort for manual transmissions in passenger cars

Abstract

GM Powertrain has in close cooperation between testing and simulation areas established a development method for shift comfort analysis for manual transmissions in passenger cars. The focus has been to improve the process from the first measurement and simulation downwards to the implementation of a design measure into production. The standardization of how to measure and how to handle data in conjunction with good analytical methods and accurate simulation has been important factors for this work.
