PROBLEM TO BE SOLVED: To make compatible the detection of an abnormality of a linear solenoid and cost reduction.SOLUTION: This control device of an automatic transmission of a vehicle comprises: a control part which controls the energization of a linear solenoid for controlling hydraulic pressure supplied to a clutch arranged at the automatic transmission from, for example, a hydraulic control device of the automatic transmission of the vehicle; and a detection part which detects a current value of the linear solenoid when the linear solenoid is energized by the control part. When it is determined that the solenoid is operated, the control part quickly starts the control of the solenoid on the basis of a threshold which is set according to a lapse time after a start of the energization for operating the linear solenoid, and a current value which is detected by the detection part.SELECTED DRAWING: Figure 3 |
