Title:
FUNCTION CONTROL DEVICE OF MOBILE SYSTEM UTILIZING BATTERY
Document Type and Number:
Japanese Patent JPH0686471
Kind Code:
A
Abstract:
PURPOSE: To maximally lengthen the operating time of all systems by a battery having limited capacity by successively suspending functions, in which a large quantity of power are consumed, on the basis of supply voltage and continuously operating only a part of important functions of the systems. CONSTITUTION: The battery 1 supplies this moving system with power. A first voltage comparing section 2 compares the voltage level of the battery 1 with a minimum reference voltage for driving a motor and output the result to a microcomputer 10. A second voltage comparing section 3 compares the voltage level of the battery 1 with the minimum reference voltage for driving a gas- sensing section and outputs the result to the microcomputer 10. The consumption of power is suppressed by inhibiting the operation of a motor drive section 7 for moving the moving system and a gas-sensing section 4 which senses the presence of gas leaks, in response to the outputs of comparison results from the first and second voltage comparing sections 2, 3 by the microcomputer 10.
