PROBLEM TO BE SOLVED: To provide an on-vehicle current controller, capable of easily correcting the dispersion in characteristics due to fluctuations of components. SOLUTION: This device is provided with an arithmetic processing unit 1 for outputting a current basic pulse width modulation signal, by calculating a current command value from engine control information and traveling control information, and for outputting a current-adjusting pulse width modulation signal from current-adjusting information, a current controller 60 for generating a current command pulse width modulation signal by modulating the current basic pulse width modulation signal by the current adjustment pulse width modulation signal, a smoothing filter 14 for converting a current command pulse width modulation signal into a DC current command signal, a comparator 21 for outputting a signal corresponding to deviation by comparing the DC current command signal with the current feedback signal, an output transistor 24 for controlling the current value corresponding to a load according to the output of the comparator, and a current-detecting means 46 for generating a current feedback signal by detecting the load currents.
