Kind Code:
A1
Abstract:
Provided is a power steering device capable of suppressing a sudden change in steering force. This power steering device comprises: a steering mechanism which transmits the steering operation of a steering wheel to steered wheels; a first actuation unit and a second actuation unit which apply steering force to the steering mechanism; and a controller which outputs a first drive command signal for driving the first actuation unit and a second drive command signal for driving the second actuation unit. The controller is equipped with an output distribution control unit which changes the output rate of the first drive command signal and the output rate of the second drive command signal, and which performs output distribution control to increase the output rate of one of the first drive command signal and the second drive command signal and decrease the output rate of the other to a value greater than 0.
