Introduction

Rahul Rangarajan is an accomplished inventor based in Rochester Hills, MI (US). He has made significant contributions to the field of vehicle transmission technology. His innovative approach has led to the development of a unique patent that addresses critical aspects of transmission shifting.

Latest Patents

Rahul Rangarajan holds a patent titled "Vehicle transmission hydraulic circuit fill time learn." This invention involves a system for controlling transmission shifting, which includes a controller that receives a shift request signal. The controller determines if a clutch has been unapplied for more than a predetermined time. If so, it calculates a maximum fill time value for hydraulic fluid to be applied to a clutch control circuit. This value is influenced by the time the clutch has been unapplied and the temperature. The system also receives a signal indicative of engine RPM flare after executing the requested shift, allowing for a modified maximum fill time value to be determined. This innovation effectively reduces air in the control circuit and minimizes flare during subsequent transmission shifts.
