Title: Innovations by Christopher R. Wiles
Introduction
Christopher R. Wiles is an accomplished inventor based in Indianapolis, IN. He has made significant contributions to the field of automatic transmission technology, holding 2 patents that showcase his innovative approach to enhancing vehicle performance.
Latest Patents
One of Wiles' latest patents is focused on the adaptive control of an automatic transmission. This invention addresses the complexities of upshifting by controlling the pressure in both the off-going and on-coming clutches. The on-coming clutch is designed to achieve maximum pressure during an initial fill time, followed by a controlled ramping process that ensures a smooth engagement. The closed-loop control mechanism utilizes on-coming clutch slip to maintain a calculated slip speed profile, allowing for automatic adjustments to improve shift quality during vehicle operation.
Another notable patent by Wiles is a method for detecting clutch tie-up during transmission shifting. This invention monitors the disengagement of the off-going clutch to identify potential failures early in the process. By analyzing turbine speed and output speed, the system can determine if clutch slip has occurred. A fail signal is generated if a set number of no-slip conditions are detected, ensuring timely intervention to prevent transmission issues.
