The invention relates to a method for controlling a disconnect clutch (6) operated by means of a hydraulic unit of a hybrid module (2) arranged between an internal combustion engine (3) and a drive wheel (14), having an electric machine (4, 5) connected upstream of the disconnect clutch (6) and downstream of the disconnect clutch (6), wherein an output cylinder operated with the working pressure of the hydraulic unit, by means of its output cylinder piston, completely actuates the disconnect clutch (6) along the ventilation path up to a contact point of the disconnect clutch (6) and from there a friction torque is formed. In order to shorten the closing time of the disconnect clutch (6), after a closing signal for closing the disconnect clutch (6), a contact point is first set by means of an output cylinder piston (115) and the disconnect clutch (6) is held here until a rotational speed balance is formed between the electric machines (4, 5).
本发明涉及用于控制布置在内燃机(3)和驱动轮(14)之间的混合动力模块(2)的借助液压单元操作的分离离合器(6)的方法,混合动力模块具有连接在分离离合器(6)之前以及连接在分离离合器(6)之后的电机(4、5),其中用液压单元的工作压力运转的输出缸借助其输出缸活塞沿着通风路径完全地操作分离离合器(6)直至分离离合器(6)的接触点并且从此处形成摩擦力矩。为了缩短分离离合器(6)的闭合时间,在用于闭合分离离合器(6)的闭合信号之后首先借助输出缸活塞(115)设置接触点并且将分离离合器(6)保持在此处,直至在电机(4、5)之间形成转速平衡。
