Introduction

John G Fowler is an accomplished inventor based in Livonia, MI (US). He holds a total of three patents, showcasing his expertise in powertrain technology and control systems. His innovative contributions have significantly impacted the automotive industry.

Latest Patents

One of his latest patents is titled "Coordinated control of transmission and accessories." This invention involves a powertrain that includes an engine, a transmission, and various accessories, such as an alternator or an air conditioning compressor. The system operates based on commands from a controller, which is programmed to coordinate commands to the transmission with those to the accessories. This coordination helps mitigate the impacts of transmission state changes. Additionally, the accessory drive torque can be adjusted to compensate for the torque required to change the speed of a transmission internal shaft. The effective inertia of the accessory may also be adjusted to maintain a powertrain's natural frequency, ensuring active damping throughout transmission state change events.

Another significant patent by Fowler is "Clutch control using dither." This invention addresses the challenges during state transitions by incorporating an oscillating component called a dither into the clutch actuator position command. This dithering technique helps avoid abrupt jumps in the actuator position due to friction when the commanded position is gradually changed. Furthermore, dither during the transition from fully released to slipping allows the natural frequency of the system to change gradually, facilitating the use of another slipping clutch for active damping based on measured oscillation.
