PURPOSE:To simplify the hydraulic control means of a continuously variable transmission, embody detection of abnormality and improve the control responsiveness. CONSTITUTION:The number of connection lines is reduced in such a way that a current command outputted from a microcomputer 100 produced a pulse width modulating signal and by inputting a current feedback signal from a solenoid 306 to the microcomputer 100, so that diagnosis of abnormality may become practicable. By connecting a resistor 352 for quick break in series to a reflux diode 351, the current reducing speed of the solenoid 306 is increased. |
