Abstract

PURPOSE: To ensure an easy detection for the form of the travelling path of an automobile, by calculating the difference of the detected value of the rotational frequencies between the inner and outer wheels of an automobile to then convert the difference into the direction varied angle to the fixed travelling section via the rotational frequency/direction varied angle converter and then displaying the curve form of the travelling path on the X-Y face via an integral network.
CONSTITUTION: The rotational frequencies of the inner and outer wheels 4 and 5 of the automobile 1 are detected by the rotation detectors 8 and 9, and then the difference of the frequencies us calculated by the arithmetic unit 10 and with every fixed travelling section. And the output of this difference is converted into the direction varies angle with every fixed section by the rotational frequency/direction varied angle converter 11 and then integrated by the integral network 12. Thus the locus of the travelling route of the automobile 1 is displayed on the display unit 13. In such way, the curve form can be detected easily for the travelling path of an automobile.
