学习混合动力车辆的发动机离合器接合点的方法
摘要：
本发明涉及学习混合动力车辆的发动机离合器接合点的方法，包括：由控制器控制将发动机与电动机连接或使发动机与电动机断开的发动机离合器，使得在控制器确认发动机和电动机的停止之后接合发动机离合器，并且执行发动机离合器的液压管路的稳定化操作；在稳定化操作之后，控制电动机使其具有特定速度；在电动机的速度稳定之后，控制发动机离合器使其接合；确定当发动机离合器接合时的电动机的扭矩变化是否等于或大于阈值；以及确定扭矩变化为阈值时的液压作为发动机离合器的接合点。
摘要（英）：

A method for learning an engine clutch kiss point of a hybrid vehicle includes: controlling, by a controller, an engine clutch which connects an engine with a motor or disconnects the engine from the motor so that the engine clutch is engaged after the controller checks stop of the engine and of the motor and stabilization operation for a hydraulic pressure line of the engine clutch is performed; controlling the motor to have a certain speed after the stabilization operation; controlling the engine clutch to be engaged after speed of the motor is stabilized; determining whether torque variation of the motor when the engine clutch is engaged is equal to or greater than a threshold value; and determining a hydraulic pressure at which the torque variation is the threshold value as the kiss point of the engine clutch.
