20120111656 | UNITED TYPE MOTOR DRIVEN POWER STEERING SYSTEM - A u-MDPS (United Motor Driven Power Steering) system includes one MDPS motor, one MDPS ECU that assists steering force using power of the MDPS motor, and has a logic implementing tilting-up/down and telescopic movement, and a multi-function generator that switches a power transmission path of the MDPS motor to the steering path for assisting a steering force, the tilt path for tilting up/down a column tube, or the telescopic path for facilitating a telescopic movement of the column tube. The multi-function generator may include a motor power converting unit, a motor power transmitting unit and a tilt•telescopic motion unit. The tilt•telescopic motion unit further includes an electromagnetic clutch, which makes it possible to implement fail-safety function by switching to a lock-manual mode of one MDPS motor. | 05-10-2012 |

20140345965 | POWER STEERING SYSTEM - A power steering system includes an EPS and a HPS. At normal times, an assist force required by a steering system is computed based on a steering torque and a vehicle speed, and the required assist force is generated by the EPS and the HPS. The torsional stiffness of a torsion bar of the HPS is equal to or substantially equal to the torsional stiffness of a torsion bar of the EPS. Therefore, even if the EPS malfunctions, it is possible to gain the steering feel similar to that when the EPS is operating properly. | 11-27-2014 |
20150041238 | VEHICLE GUIDANCE SYSTEM - A vehicle guidance system is disclosed where the vehicle includes a steering wheel assembly including a steering wheel and a hub, the hub connected to a steering shaft rotatable about a steering wheel axis within a steering column for steering the vehicle. The vehicle guidance system includes a receiver for receiving a position indication signal, a steering controller for generating a steering control signal based on the position indication signal and a drive assembly to directly drive the steering wheel assembly responsive to the steering control signal. The drive assembly generates a torque about a drive axis to rotate the steering wheel assembly, wherein the drive axis of the drive assembly is coaxial to the steering wheel axis. | 02-12-2015 |
