Latest Patents

Holthoff holds a patent for a "Fuel Efficient Power Steering Control System and Method." This invention focuses on a system and method for controlling the flow outlet from a hydraulic pump. The system is designed to provide the necessary flow to execute the driver's steering commands while reducing the average torque requirement of the hydraulic pump. This innovative method improves fuel economy by unloading the vehicle's accessory drive and offers a variable assist power steering feature. The Fuel Efficient Power Steering (FEPS) control algorithm optimally regulates flow by actuating an electronic flow control device in the pump assembly. This device increases hydraulic fluid flow to the steering gear when additional assist is needed and reduces flow to enhance fuel economy when it is not required. The desired flow control device current is calculated based on vehicle speed and steering wheel rate, with additional input signals such as steering angle or engine RPM for enhanced functionality.
