Patent ID: 6841955

Claim:
A moving body drive control device for controlling drive of a moving body driven by at least a first motor and a second motor to move the moving body at a specified target speed. the drive control device comprising: a detector detecting a velocity of the moving body; a first motor driving circuit forming a circuit that determines a direction of current flow of the first motor by a combination of ON/OFF state of switches; a second motor driving circuit forming a circuit that determines a direction of current flow of the second motor by a combination of ON/OFF state of switches; and a controller controlling the first and second motor driving circuits; wherein the controller controls the first and second motor driving circuits based on detection of the detector such that the controller brings one of the first and second motor driving circuits into operation as a power source and the other of the first and second motor driving circuits into operation as a regenerative brake for reducing the velocity of the moving body, wherein the controller further comprises a pulse generating circuit for generating a first pulse for controlling the first motor and a second pulse for controlling the second motor based on detection of the detector; and wherein the controller controls a length of actuating time that the first and second motors are actuated as the power source and the regenerative brake by controlling a pulse-length being input to the first and second motors by using a pulse-width modulation control.
