Abstract

본 발명은 자동차의 속도를 검출하기 위한 장치로서 발명의 주된 목적은 구동력을 가지지 않은 바퀴의 축에 센서를 장치하므로서 진행하지 않고 헛바퀴도는 경우 속도가 나타나지 않도록 하고, 또 후진을 할 경우에도 바퀴의 축이 회전하면 속도가 있는 것으로 표시하는 등 보다 정확한 값을 검출토록 하는데 주된 목적이 있고, 또 한편으로는 상기한 검출값을 E.C.U를 통해 별도의 S-RAM에 저장되도록 하여 임의 조작을 할 수 없도록 하기 위한 것이다.The present invention is a device for detecting the speed of the vehicle, the main object of the invention is to install the sensor on the axis of the wheel does not have a driving force, so that the speed does not appear when the wheel does not proceed without turning, even when reversing Its main purpose is to detect more accurate values, such as marking the speed as the axis rotates. On the other hand, the above detected values can be stored in a separate S-RAM through the ECU so that arbitrary operation cannot be performed. It is to.

그리고 이를 위한 특징적인 구성은 차축의 일측 표면상에 매설한 영구자석과, 상기한 차축의 상부에 고정된채 상기한 영구자석의 펄스를 감지하는 센서로 이루어진 검출기구를 설치하되, 자전능력을 가지지 못한 채 회전하는 차축상에 설치하며, 상기한 검출기구에 의한 검출값을 이.씨.유를 통해 속도계 및 거리계에 표시되도록 하는 한편, 기억장치에 그 값을 저장토록 하는데 있다.And a characteristic configuration for this is to install a detector mechanism consisting of a permanent magnet embedded on one surface of the axle, and a sensor for detecting the pulse of the permanent magnet fixed to the upper portion of the axle, but has a rotating capability It is installed on the axle which does not rotate, and the detection value by the detector is displayed on the speedometer and the rangefinder through E.C.U., while the value is stored in the storage device.
