The subject of the present invention is a method for limiting the current in a device of "H-bridge" type comprising a plurality of transistors (T1, T2, T3, T4), characterized in that it comprises thefollowing steps: detection of a failure in a transistor (T) from among said plurality of transistors; disabling of said transistor in which a failure has been detected; detection in the transistors opposite to said transistor, of the discharging of the energy accumulated at output; and disabling of the other transistors of said plurality of transistors. The present invention also relates to a system for limiting the current in a device of "H-bridge" type comprising a plurality of transistors. 本发明是针对种用于在包括多个晶体管（T1、T2、T3、T4）的"H桥"型装置中限制电流的方法，其特征在于其包括以下步骤：* 检测所述多个晶体管（T1、T2、T3、T4）中的晶体管（T）上的故障；* 关断在其上检测到故障的所述晶体管（T）；* 在与所述晶体管（T）相对的晶体管上检测输出端上积累的能量的放电；以及* 关断所述多个晶体管（T1、T2、T3、T4）中的其它晶体管。本发明还涉及种用于在包括多个晶体管的"H桥"型装置中限制电流的系统。
