To suppress the damage of an electromagnetic valve resulting from electricity-carrying without causing a cost increase and the complication of a structure, in an opening/closing control device of a soft top roof.SOLUTION: An opening/closing control device comprises: a plurality of electromagnetic valves for controlling the supply of hydraulic pressure to a hydraulic cylinder by on/off-switching; a thermistor of a pump motor; and an ECU for calculating estimation temperatures TV of the electromagnetic valves, and controlling on/off-states of the electromagnetic valves. The ECU uses a function having a positive inclination α on the basis of a detection temperature TS of the thermistor when at least one of the electromagnetic valves is turned on, whereas when all the electromagnetic valves are turned off, calculates the estimation temperatures TV of the electromagnetic valves by using a function having a negative inclination -β, also when the estimation temperatures TV are equal to a first threshold TP1 or higher, prohibits electricity-carrying to the electromagnetic valves which correspond to opening operations, whereas when the estimation temperatures TV are equal to a second threshold TP2 or higher, entirely prohibits the electricity-carrying to the electromagnetic valves.SELECTED DRAWING: Figure 7
【課題】ソフトトップルーフの開閉制御装置において、コスト上昇や構造の複雑化を招くことなく、通電に起因する電磁バルブの損傷を抑制する。【解決手段】ON/OFF切り替えで、油圧シリンダへの油圧の供給を制御する複数の電磁バルブと、ポンプモータのサーミスタと、電磁バルブの推定温度TVを算出して、電磁バルブのON/OFFを制御するECUと、を備える開閉制御装置である。ECUは、サーミスタの検出温度TSに基づき、且つ、電磁バルブが1つでもONの場合には正の傾きαの関数を用いる一方、電磁バルブがすべてOFFの場合には負の傾き−βの関数を用いて、電磁バルブの推定温度TVを算出し、推定温度TVが第1閾値TP1以上の場合には、開操作に対応する電磁バルブへの通電を禁止する一方、推定温度TVが第2閾値TP2以上の場合には、電磁バルブへの通電を全面的に禁止する。【選択図】図7
