Abstract

PURPOSE:To achieve suitable speed control by detecting and controlling a speed of a car always correctly even at running on a curve, in the speed control of a self-running surface car requiring automatic and unattended remote control running. CONSTITUTION:When a car 1 goes straight, detected outputs of speed detectors 50 and 51 are almost equal and those of detectors 60 and 61 are also similar, and suitable speed control can be achieved by any output of the detectors. When the car 1 rapidly turns, since the radius of swing of inside and outside wheels 10 and 11 is different, the output of the detectors 50 and 51 for left and right wheels causes a difference. The detected outputs of the detectors 50 and 51 are added at 55 after multiplying suitable coefficients respectively by coefficient elements 500 and 510, and the sum is further multiplied by a suitable coefficient 5 and treated as a speed of the car 1. The value is compared and subtracted by a reference value Vr at a subtractor 55 and driving motors 30 and 31 are controlled according to the difference.
