  • Perception of a road profile by the varying a gain as a function of a vehicle speed and steering wheel torque
    Patent number: 11597432
    Abstract: A power-steering system for a motor vehicle includes a steering wheel and an assistance motor controlled by a closed-loop regulation system, the regulation system determining a motor torque of the assistance motor as a function of a measured steering-wheel torque, using at least one “setpoint monitoring” arm calculating a component of the motor torque, referred to as “variant motor torque”, by subtracting a set steering-wheel torque from the RFe corresponding to the sum of the measured steering-wheel torque and the motor torque, wherein the variant motor torque is multiplied by a gain determined by a three-dimensional map as a function of a vehicle speed and the measured steering-wheel torque.
