Title: Detecting device of steering angle
Inventor: IWASHITA SHIGEO
IPC: G01B21/22
Filed: 1984-07-03
Abstract: PURPOSE:To enable the detection of an angle of rotation of a steering wheel starting from the neutral position of this wheel, i.e. a steering angle, by detecting an angle of rotation of maximum frequency as the neutral position, and by computing an angle of rotation starting from said neutral position. CONSTITUTION:A detecting device is so designed that it detects an angle of rotation of maximum frequency as a neutral position and that an angle of rotation is computed with this neutral position as a starting point. In other words, the neutral position is determined from the frequency of an angle of relative rotation by an encoder 10, and a steering angle is computed therefrom. Accordingly, the steering angle can be detected accurately from the state of running after a power source is made even when the content of the steering angle is erased by the turning-OFF of the power source.
