Control Oriented Modeling Of An Automotive Drivetrain For Anti-Jerk Control, Gurijala Venkat Prithvi Reddy Jan 2018

Control Oriented Modeling Of An Automotive Drivetrain For Anti-Jerk Control, Gurijala Venkat Prithvi Reddy

Dissertations, Master's Theses and Master's Reports

Drivability is an important metric during the development of an automobile. Calibration engineers spend a significant amount of time trying to improve the drivability of vehicles for various driving conditions. With an increase in the available computational power in an automobile, novel model-based methods are being implemented for further improving the drivability, while reducing calibration time and effort. Phenomenon known as clunk and shuffle, which are caused due to backlash and compliance in the driveline, are a major cause of issues related to drivability and noise, vibration and harshness (NVH) during tip-in and tip-out scenarios.

This thesis focuses on developing ...


Drivability Of The Fiat 500 Multi-Air Engine Under Simulated Poor Maintenance, Andrew Croxell Oct 2016

Drivability Of The Fiat 500 Multi-Air Engine Under Simulated Poor Maintenance, Andrew Croxell

ASA Multidisciplinary Research Symposium

The FIAT Multi-Air valve-train uses hydraulic, mechanical, and electric components to control engine intake valves for more precise combustion. However, the incorporation of electronics and hydraulics creates additional potential for drivability issues. This study will simulate poor vehicle maintenance in a FIAT 500 Multi-Air engine to identify drivability concerns generated.
