Title: Electric power steering device
Inventor: CHIKARAISHI KAZUO
IPC: B62D6/10
Filed: 1999-11-09
Abstract: PROBLEM TO BE SOLVED: To effectively restrain generation of noise. SOLUTION: A torque sensor, when a torsional condition of a torsion bar is within a specified angle, linearly outputs a detection signal converted at a first conversion ratio to the torsional condition thereof, and then when the torsional condition thereof exceeds the specified angle but is within a limit angle, outputs a detection signal converted at a second conversion ratio being smaller than the first conversion ratio.
