The disclosure provides 'a system for controlling an engine disconnect clutch in a hybrid vehicle'. A vehicle includes: an engine having a crankshaft, an electric machine having a rotor, a disconnect clutch having an input secured to the crankshaft and an output secured to the rotor, a hydraulic pump mechanically powered via rotation of the rotor and configured to supply hydraulic fluid to the actuate the disconnect clutch, a torque converter having an impeller secured to the rotor, and controller. The controller is programmed to, responsive to a speed of the impeller decreasing to less than a first threshold, which is indicative of a subsequent shutdown of the hydraulic pump, and responsive to the disconnect clutch being open while the engine is shut down, advance the disconnect clutch to a touch point where opposing sides of disconnect clutch make contact but substantially zero power is transferred between the engine and the electric machine.
本公开提供了“用于控制混合动力车辆中的发动机分离离合器的系统”。一种车辆包括:具有曲轴的发动机;具有转子的电机;分离离合器,所述分离离合器具有固定到所述曲轴的输入端和固定到所述转子的输出端;液压泵,所述液压泵经由所述转子的旋转被机械地提供动力并且被配置为供应液压流体以致动所述分离离合器;变矩器,所述变矩器具有固定到所述转子的泵轮;和控制器。所述控制器被编程为响应于所述泵轮的转速减小到小于指示所述液压泵的随后停机的第一阈值,并且响应于在所述发动机停机时所述分离离合器打开,将所述分离离合器推进到接触点,在所述接触点处,分离离合器的相对侧接触,但在所述发动机与所述电机之间传递基本上为零的功率。
