A device for detecting the turning angle and steering of a vehicle steering wheel comprises a steering wheel sleeve and a photoelectric detection unit. An annular colored tape is arranged on the rear side of the steering wheel cover and is divided into 256 continuous areas at equal angles, the 256 areas are numbered in sequence and are respectively numbered as 0-255, and the colors of all the areas are different. The photoelectric detection unit comprises an outer shell, a power supply, a controller and a memory are arranged in the outer shell, three photoelectric sensors capable of identifying colors are arranged on the front side of the outer shell, each photoelectric sensor is fixed on the front side of the outer shell through a universal joint, and the photoelectric sensors and the memory are connected with the power supply through the controller. Along with the synchronous rotation of the colored tape and the steering wheel, the photoelectric sensor detects red, green and blue values of colors in different areas on the colored tape, the turning angle and the turning direction of the steering wheel can be obtained and output in real time through analysis and calculation of the controller, and the system is stable, reliable, convenient to install, not prone to interference and free of influence on driving safety.

    一种检测车辆方向盘转角及转向的装置,包括方向盘套和光电检测单元;方向盘套后侧设有环形色带,环形色带等角度分隔为256个连续的区域,并且对这256个区域依次编号,分别编为0号‑255号,每个区域的颜色均不相同;光电检测单元包括外壳体,外壳体内设有电源、控制器、存储器,外壳体前侧设有三个可以识别颜色的光电传感器,每个光电传感器均通过万向节固定于外壳体前侧,光电传感器、存储器均通过控制器与电源相连。随着色带与方向盘的同步转动,光电传感器检测到色带上不同区域颜色的红、绿、蓝色量值,通过控制器分析计算,可实时获取并输出方向盘的转角及转向,系统稳定可靠,便于安装,不易受干扰,不影响驾驶安全。
