PROBLEM TO BE SOLVED: To provide a hydraulic control device for a road-rail vehicle, capable of preventing retreat operation easily and surely while preventing idling of an iron wheel, in slope start on a rail track.SOLUTION: A hydraulic control device controls brakes of iron wheels of a road-rail vehicle. A vehicle speed sensor detects that the road-rail vehicle is stopped (S1), an angle sensor detects that the road-rail vehicle is positioned on a slope face (S2), and a brake sensor detects operation of the brake (S3). When these conditions are satisfied, braking of the iron wheels by the brakes is maintained (S4). Then, based on an inclination angle detected by the angle sensor, a hydraulic oil pressure (required uphill pressure) which is required for the road-rail vehicle for going up the hill, is calculated (S5). When a pressure difference ΔP between ports of hydraulic motors for driving the iron wheels becomes equal to the required uphill pressure (S6), operation of the brakes is released (S7).

    【課題】軌道上の坂道発進に際して鉄輪の空転を防止しつつ後退動作を簡単且つ確実に防止する軌陸車用油圧制御装置の提供。【解決手段】この油圧制御装置は、軌陸車の鉄輪のブレーキを制御する。車速センサが軌陸車が停止していることを検知し(S1)、角度センサが軌陸車が斜面上に位置することを検知し(S2)、ブレーキセンサがブレーキの作動を検知する(S3)。この条件が揃えば、ブレーキによる鉄輪の制動が維持される(S4)。角度センサが検知した傾斜角度に基づいて軌陸車が登坂するために必要な油圧(必要登坂圧力)が算出される(S5)。鉄輪を駆動する油圧モータのポート間の圧力差ΔPが必要登坂圧力に等しくなったときに(S6)、ブレーキの作動が解除される(S7)。【選択図】図6
