Input/output device and steering measurement device

Abstract

An input/output device includes: an identification signal command unit that outputs, to an electric power steering device that adds a steering assist force to a steering provided in a vehicle, an identification signal for identifying a parameter of the electric power steering device, or an instruction signal that instructs the electric power steering device to start outputting the identification signal; and a parameter identification unit that identifies the parameter of the electric power steering device from a response of the electric power steering device to the identification signal, in which the parameter identification unit identifies the parameter of the electric power steering device based on a response to a first identification signal for identifying a linear parameter and a second identification signal for identifying a nonlinear parameter, which are output when the steering is in a predetermined rotation state.
