To provide an electricity-carrying control device of a coil which can elongate a life.SOLUTION: A control device 8 comprises a switching element 64 arranged at a power supply line 62 being an electricity-carrying passage to a solenoid coil 41, and a microcomputer 71 for creating a PWM control signal S for turning off the switching element 64. The microcomputer 71 performs assist control for creating the PWM control signal S having a duty ratio based on a vehicle speed V and a steering angle θs according to a traveling state of a vehicle, or standby control for creating the PWM control signal S having a duty ratio at which a flow rate of a working fluid supplied to a hydraulic actuator reaches a prescribed flow rate or smaller. Then, when the vehicle speed V is higher than a middle/high-speed threshold at the execution of the assist control and the standby control, the microcomputer 71 sets a PWM frequency of the created PWM control signal S to a low frequency.SELECTED DRAWING: Figure 2

    【課題】長寿命化を図ることのできるコイルの通電制御装置を提供する。【解決手段】制御装置8は、ソレノイドコイル41への通電経路となる電源線62に設けられたスイッチング素子64と、スイッチング素子64をオンオフさせるPWM制御信号Sを生成するマイコン71とを備える。マイコン71は、車両の走行状況に応じて、車速V及び操舵角θsに基づくデューティ比のPWM制御信号Sを生成するアシスト制御、又は油圧アクチュエータに供給する作動油の流量が所定流量以下となるようなデューティ比のPWM制御信号Sを生成するスタンバイ制御を実行する。そして、マイコン71は、アシスト制御及びスタンバイ制御の実行時において、車速Vが中高速閾値よりも大きい場合には、生成するPWM制御信号SのPWM周波数を低周波数に設定する。【選択図】図2
