Latest Patents

Jean-Marie Loisel's latest patents include an analog-to-digital converter and an electronic power steering method and apparatus. The analog-to-digital converter is designed for a power steering control unit used in electric motor-assisted vehicle power steering systems. This control unit features two microprocessor controllers that monitor vehicle speed and torque applied through the steering column. It calculates a duty cycle for the assist motor, allowing for adjustments via four control switches on the vehicle dashboard. Each microprocessor not only optimizes motor energization but also monitors performance. If performance deviates from expected ranges, the assist is removed, and corrective steps may be taken. Additionally, an electrically erasable read-only memory (EEROM) is coupled to the microprocessors to store constants for energization sequences and performance indicators for diagnostics.
