Publication number: 20160144890Abstract: A steering control method for a steer-by-wire (SBW) system includes receiving an output value reflecting a current steering wheel state and a current driving state of a vehicle. A current Ackerman effect value of the vehicle is determined according to the output value. If the current Ackerman effect value is different from an optimum Ackerman effect value which is determined according to the output value, toe angles of right and left wheels are changed and controlled such that the current Ackerman effect value becomes the optimum Ackerman effect value.Type: ApplicationFiled: May 14, 2015Publication date: May 26, 2016Inventors: Jong Min KIM, Soo Bo PARK

Publication number: 20140074355Abstract: A hybrid steering system and a method for controlling the same. A motor driving power steering (MDPS) module at the rear end of a steering wheel includes a first torsion bar connected to a steering wheel shaft, a first torque sensor for measuring the torque of the first torsion bar, and an MDPS motor for applying the torque to the steering wheel shaft. An electro-hydraulic power steering (EHPS) module at the rear end of the MDPS module includes a second torsion bar connected to the steering wheel shaft and a hydraulic mechanism for applying hydraulic steering power. A control unit controls both the torque of the MDPS motor and the steering power of the hydraulic mechanism depending on the speed or steering angle of a vehicle so that both powers from the MDPS motor and the hydraulic mechanism can be applied to the steering wheel shaft.Type: ApplicationFiled: December 7, 2012Publication date: March 13, 2014Applicant: Hyundai Motor CompanyInventors: Jong Min KIM, Soo Bo Park
