PURPOSE:To prevent a battery-available time from being shortened at a low temperature, by regulating the set values of the respective control elements of a running controller according to the temperature of a battery. CONSTITUTION:The running controller 1 of an unmanned carrier is provided with a differential amplifier 3 for finding an output difference between two pick-up coils 2 to amplify the difference, a deviation gain control section 4 with the output of the differential amplifier 3 multiplied by a gain, a running control section 5 for selecting a running speed so that the output signal of the deviation gain control section 4 may be zero, and an accelerated or reduced speed control section 6 for receiving the output signal from the running control section 5 and for controlling a time constant on accelerating or reducing the speed of the unmanned carrier. By a temperature monitor 11, according to the temperature of a battery 10, the set value of the running speed at the running control section 5, a gain value to be multiplied at the deviation gain control section 4, and an accelerated or reduced speed time constant at the accelerated or reduced speed control section 6 are controlled. |
