Title: Lian Yu and Transmission Innovation.

Introduction

Lian Yu is an inventor associated with Whitestown, Indiana, and Allison Transmission, Inc. His patent work concerns monitoring the performance of multi-speed planetary transmissions.

Latest Patents

The provided information identifies one patent associated with Yu: “Slip Speed Monitoring of a Multi-Speed Planetary Transmission.” The invention describes a transmission with planetary gearsets and selective couplers that can provide at least eight forward speed ratios. One configuration uses four planetary gearsets and six selective couplers, comprising two clutches and four brakes.

A transmission controller operates the selective couplers and monitors their condition. Speed sensors placed on selected rotating components can provide enough information to monitor slip speeds across all the couplers. The record lists 1 patent for Yu.

Career Highlights

Yu’s listed patent reflects work on transmission control and component-health monitoring. The disclosed approach uses sensor data to assess coupler slip without requiring a separate speed sensor for every coupler.

Collaborations

The supplied information lists Tristan Cox as Yu’s coworker at Allison Transmission, Inc. It does not specify whether Cox collaborated on the patent.

Conclusion

Lian Yu’s listed invention focuses on monitoring selective-coupler slip in multi-speed planetary transmissions, supporting transmission control and health assessment.
