In general, when there is no fixation, the distance between the tire and the sensor is about 10cm. When the distance is set to 10cm or less due to the fixation, the sensor can detect this.

The sensor and tire separation can be calculated as follows.

Distance from tire = ultrasonic echo wave arrival time × sound velocity

Here, the reflected wave arrival time means a time from the tire signal to the start of the reflected signal.

In this way, the signal detected by the sensor 10 is sent to the control unit 11 to be described later, by outputting a control signal for the actuator operation in the control unit 11, a full-fledged removal work can be started.
