Title: Chris Mantjios: Innovator in Electric Power Steering Systems
Introduction
Chris Mantjios is a notable inventor based in Rochester, MI (US), recognized for his contributions to the field of electric power steering systems. With a total of 2 patents, he has developed innovative methods that enhance the performance and reliability of these systems.
Latest Patents
One of Mantjios's latest patents is focused on active disturbance rejection for electrical power steering systems. This method controls disturbances associated with electric power steering (EPS) systems by maintaining an original assist torque to feedback signals, such as column torque. It minimizes the impact from disturbance sources, ensuring that the original steering feel is preserved. The method also considers the interaction of the rejection feature with other EPS functions. In one embodiment, relationships for isolating disturbances are achieved through a combined feedback and feed-forward compensator.
Another significant patent involves a method of controlling an electric motor of a power steering system with at least three windings. In this invention, a control unit applies current to the windings of the electric motor to generate total torque, which is determined from a set-point torque for steering assistance and a set-point torque for damping. A damping set-point circuit ascertains the damping torque, while a steering assist set-point circuit determines the torque for steering assistance. Additionally, a monitoring circuit oversees the function of the motor windings, outputting an error signal in case of a malfunction, which leads to a reduction in the set-point torque for steering assistance.
