接か明確にわかる。 Next, the operation will be described. When a car approaches an obstacle, the capacitance between the detector 1 and the obstacle changes in inverse proportion to the distance between the sensor 1 and the obstacle. In that case, the shorter the distance, the greater the change in the output of the detection circuit 2 due to a small change in distance. Furthermore, if the change is viewed as a differential amount per unit time, the faster the speed, the greater the output. This amount of change is determined by the level determination circuit 3 and displayed on the level display section 4. The level display section 4 is located in a part of the corner pole 5 that can be seen from the driver's seat, so that the driver can clearly see how close the vehicle is.

なお、レベル表示部４は、レベルに応じて色が
変化するようにすれば認識が一層容易となる。 Note that the level display section 4 can be more easily recognized if the color changes depending on the level.

Also, if the color is changed according to the level, recognition becomes easier.
