Patent application numberDescriptionPublished
20090216407ELECTRICAL POWER STEERING SYSTEM FOR A MOTOR VEHICLE - An electrical power steering system for a motor vehicle. The system includes a rack actuator and a sensor for measuring torque applied to the steering wheel by the driver, the actuator and the sensor being arranged on the steering column, respectively between the steering wheel and the rack, and between the actuator and the steering wheel. The system develops a final assistance torque of the electrical power steering, which is adapted to simulate an identical localization of the rack actuator and the torque measuring sensor on the steering column, such that the Bode diagram phase representing the operation of the system is essentially nil at the two main frequencies of the mechanical resonance of the system.08-27-2009
