Claims (1)
状の反射面をステアリングホイールに同軸状に設
ける一方、この反射面に向けて発光する発光素子
と前記反射面からの反射光を受ける受光素子の組
合わせを備え、受光信号のレベル変化に基づいて
舵角及び転舵速度を求める検出部を静止部に取付
けたことを特徴とする自動車用舵角検知装置。 A ring-shaped reflective surface whose reflectance changes at least in the circumferential direction is provided coaxially on the steering wheel, and a combination of a light-emitting element that emits light toward this reflective surface and a light-receiving element that receives light reflected from the reflective surface. What is claimed is: 1. A steering angle detection device for an automobile, characterized in that a detection section for determining a steering angle and a steering speed based on changes in the level of a received light signal is attached to a stationary section.
