<p>PROBLEM TO BE SOLVED: To provide an electronic valve drive unit which can sufficiently apply a voltage to an electronic valve at a start of in-boosting drive control for valve-opening the electronic valve during a boosting operation of a boosting voltage to a set value by a boosting circuit, and thereby can improve the controllability of the electronic valve.SOLUTION: In an electronic valve drive unit 1, drive control for valve-opening an electronic valve by applying a boosting voltage generated by a boosting circuit to the electronic valve is performed, and it is predicted whether or not there is performed in-boosting drive control being drive control which is performed during a boosting operation for boosting the boosting voltage VC which is lowered accompanied by the drive control to a set voltage by the boosting circuit (steps 1, 3), and when it is predicted that the in-boosting drive control is performed, the drive control is performed so that the boosting voltage at a start of the in-boosting drive control approximates the set voltage (steps 4, 5).</p> |
