A method and system for controlling an engine clutch of a vehicle includes: determining whether a learning mode entry condition is satisfied according to whether a kick-down occurs during execution of variable hydraulic control of the engine clutch and based on a degree to which the engine clutch slips; deriving and storing, when the vehicle state satisfies a predetermined learning mode entry condition, a learning hydraulic pressure value for suppressing slipping that will occur when a kick-down occurs during execution of the variable hydraulic pressure control so that slipping does not occur; and when the same kick-down situation occurs, calculating a final hydraulic pressure by adding the hydraulic pressure compensation value to the target hydraulic pressure, and controlling the engine clutch using the calculated final hydraulic pressure.

    一种控制车辆的发动机离合器的方法和系统,包括以下步骤:根据在发动机离合器的可变液压控制执行期间是否发生强制降档,并且基于发动机离合器发生打滑的程度,确定是否满足学习模式进入条件;当车辆状态满足预定的学习模式进入条件时,导出并存储学习液压值,该学习液压值用于抑制在可变液压控制执行期间发生强制降档时将要发生的打滑,以使得不发生打滑;并且当发生相同的强制降档情况时,通过将液压补偿值与目标液压相加来计算最终液压,并使用计算出的最终液压来控制发动机离合器。
