Travel controller of operatorless traveling vehicle

Abstract

Abstract PURPOSE:To increase a range of a slope to be applied by traveling a vehicle at a constant speed on a smooth descent and decelerating on a sharp descent. CONSTITUTION:When a start command 22 is output, a gradually rising voltage is output from a start compensator 16. A comparator 25 applies a PWM signal in response to the voltage to a transistor 2 to control an armature current. On the other hand, the output of the compensator 16 outputs the highest voltage to a peak priority circuit 9 for the prescribed time. A comparator 10 applies a PWM signal in response to the output of the priority circuit 9 to a transistor 6 to control a field current. When the speed of a vehicle is accelerated, the output of a rotation detector 12 becomes the highest input of the circuit 9. When the slope of a descent becomes sharp, the voltage of a resistor 3 becomes the prescribed value or higher, and the deceleration command signal from a decelerator 15 becomes the highest input of the circuit 9.
