Title: James R. Bartshe: Vehicle Control and Diagnostic Inventions.

Introduction

James R. Bartshe is an inventor based in Plymouth, Michigan, whose work focuses on vehicle systems, hydraulic pressure management, and friction-element diagnostics. He is associated with GM Global Technology Operations, Inc. His portfolio includes 2 patents.

Latest Patents

Bartshe’s listed patents address two vehicle-control challenges.

“System and Method of Managing Line Pressure in a Vehicle During a Fault Pending Condition” describes a system that measures hydraulic pressure and regulates fluid flow. When a potential fault is detected, the control module increases pressure and repeatedly enables and disables an actuator to assess whether it has failed.

“System and Method of Detecting a Failed Friction Element” concerns diagnosing a friction element by monitoring the difference in rotational speeds between its driving and driven mechanisms. During a shift, the control processor induces a slip condition and identifies a possible failure if the measured slip speed remains substantially zero.

Career Highlights

Bartshe’s patent work reflects an emphasis on control strategies that help vehicle systems respond to faults and identify component failures. His inventions combine sensors, actuators, and control processing to monitor system behavior and support diagnostics.

Collaborations

Bartshe’s listed coworkers include Syed Naqi and Ali K. Naqvi. His work is associated with GM Global Technology Operations, Inc.

Conclusion

James R. Bartshe’s patents focus on managing hydraulic line pressure and detecting friction-element failures, contributing diagnostic and control approaches for vehicle systems.
