摘要： A rotation transmitting apparatus comprises a first sun gear (3) joined to a first shaft (1) so as to rotate interlockingly, a second shaft (2) arranged to the first shaft (1) coaxially, a second sun gear (4) joined to the second shaft (2) so as to rotate interlockingly, a first planetary gear (5) meshed with the first sun gear (3), a second planetary gear (6) rotating with the first planetary gear (5) and meshed with the second sun gear (4), and a carrier (7) supporting the first and second planetary gears (5) and (6) and arranged to be driven by a differential electric motor (10). In particular, the number of teeth of each of the first and second sun gears (3) and (4) and the first and second planetary gears (5) and (6) is determined so that the ratio of a torque applied to the second shaft (2) to a torque applied to the first shaft (1) ranges from 1:0.7 to 1:0.9.

摘要： A control section (10) of a vehicle steering system has a steer-by-wire mode, a power steering mode, and a transition mode. In the steer-by-wire mode, a steering actuator (19) is controlled for steering and a reaction force actuator (11) is controlled for reaction force. In the power steering mode, steering assistance control is performed with either of the steering actuator (19) and the reaction force actuator (11) caused to function as an assistance unit. In the transition mode, in a transition period from either of the steer-by-wire mode and the power steering mode to the other, the reaction force actuator (11) is controlled for reaction force.
