Title:
ステアリング角の絶対値を測定するための光学式ステアリング角センサ
Document Type and Number:
Japanese Patent JP5214626
Kind Code:
B2
Abstract:
An optical steering angle sensor for determining the absolute value of the steering angle even when a steering wheel has been revolved several times is provided, having a stator, a rotor with a barcode and evaluation electronics. In one form, the invention provides for the rotor to have a track groove which is arranged in the form of a worm in order to determine the number of revolutions, which track groove has an associated driver finger on the stator, which engages in the track groove and is arranged in a bearing such that it can pivot, and has a holder for a magnet which can pivot with the driver finger and which driver finger has an associated stationary Hall sensor, which is provided in an evaluation circuit.
