Abstract

PURPOSE: To reduce the vibration of front and back parts of a wheel by detecting accurately the distance deviation from a running reference line (command value) and the angle (shape angle) made by the wheel and the reference line to determine the steering direction.
CONSTITUTION: Reference laser beam LB is divided into two beams LB1 and LB2 by half-mirror 20. Beam LB1 is condensed through cylinder lens 21, and position sensor 22 outputs position signal e corresponding to the light receiving position from center position P. Beam LB2 is irradiated to displacement detection part 23, and displacement detection part 23 constituted by four light receiving elements D1 to D4 outputs a position signal corresponding to the light receiving position. Operation circuit 24 calculates shape angle Δθ on a basis of input signal eb and outputs signal eθ. Then, horizontal displaced position ΔX is calculated on a basis of input signals e1 to e4 to output signal ex.
