Abstract
In a non-stage transmission control system, the output current instruction signal of a microcomputer is provided as a pulse-width-modulated signal, with a result that the number of signal lines from the microcomputer is reduced. Furthermore, the current feedback signal of a solenoid is applied to the microcomputer, for detection of abnormal conditions, and a quick break resistor is connected in series to a feedback diode to increase the current reduction rate of the solenoid.
