PURPOSE:To indicate directions exactly with a simple constitution, by subjecting the outputs from a vertical direction angular sensor, a horizontal direction angular sensor and a speed sensor. CONSTITUTION:A vertical direction change angle lambda and a horizontal direction change angle theta are detected by a vertical direction angular sensor 5 and a horizontal direction angular sensor 6, respectively, and by function arithmetic circuits 8, 9 f(lambda) and f(theta) are calculated. These outputs and the output v(t) of a speed sensor 7 are inputted into an arithmetic circuit 14, 15 thereby, vertical directon change signal and a horizontal direction change signal are obtained. These signals are indicated on a vertical direction indicator 18 and a horizontal direction indicator 19. |
