Introduction
Ashraf A Zeid is a notable inventor based in Troy, MI (US). He has made significant contributions to the field of automotive technology, particularly in power steering systems and motor control. With a total of 2 patents, his work reflects a commitment to enhancing vehicle performance and safety.
Latest Patents
One of his latest patents is for an "Electric power assist torque check." This innovative power steering system incorporates at least one motor to assist the operator in steering the vehicle. It features a computer or microprocessor controller that adjusts the motor assist torque based on specified requirements defined by boost curves. A second microprocessor controller calculates the output of the power steering motor and ensures that the power assist torque aligns with the driver's input. If the relationship between the driver torque and power assist torque falls outside specified bounds, the system may enter a power-off state to prevent undesirable torque generation.
Another significant patent is for "Active current-limiting control for dc motor speed regulation." This motor controller regulates the speed of a dc motor while limiting its input current. It includes an electronic control unit, a current sensor, and a speed sensor. The controller applies varying voltage to maintain motor speed under varying loads and monitors input current to predict potential overcurrent conditions. When necessary, it switches to a current-limiting mode to protect the motor and ensure optimal performance.
