Abstract
An on-board current control device comprising: a processing unit operating a current command value from engine control information and driving control information, outputting a current basic pulse width modulating signal, and outputting a current adjusting pulse width modulating signal from current adjusting information; a current regulator modulating the current basic pulse width modulating signal by the current adjusting pulse width modulating signal and generating a current command pulse width modulating signal; a smoothing filter converting the current command pulse width modulating signal to a current command signal like a direct current; a comparator comparing the current command signal like the direct current with a current feed-back signal and outputting a signal corresponding to thus obtained deviation; an output transistor controlling a current value to a load by an output from the comparator; and a current detecting means detecting the load current and generating the current feed-back signal, whereby dispersion of characteristics caused by dispersion of components can be easily corrected.
