The invention provides a control system for an engine disconnect clutch in a hybrid vehicle. A vehicle includes an engine, an electric machine, a disconnect clutch, and a controller. The engine and the electric machine are each configured to generate power. And the separation clutch is arranged between the engine and the motor. The controller is programmed to close the disconnect clutch to transfer power from the electric machine to the engine in response to a command to start the engine. The controller is also programmed to control the torque of the disconnect clutch via increasing the pressure applied to the disconnect clutch based on a first order model of the pressure applied to the disconnect clutch. The controller is also programmed to adjust the model based on a difference between an expected pressure of the disconnect clutch and a measured pressure of the disconnect clutch during a time period prior to transmitting torque through the disconnect clutch.

    本公开提供了“用于混合动力车辆中的发动机分离离合器的控制系统”。一种车辆包括发动机、电机、分离离合器以及控制器。所述发动机和所述电机各自被配置为产生动力。所述分离离合器设置在所述发动机与所述电机之间。所述控制器被编程为响应于起动所述发动机的命令,闭合所述分离离合器以将动力从所述电机传递到所述发动机。所述控制器还被编程为经由基于施加到所述分离离合器上的压力的一阶模型增加施加到所述分离离合器上的所述压力来控制所述分离离合器的所述扭矩。所述控制器还被编程为基于在通过所述分离离合器传递扭矩之前的时间段期间所述分离离合器的预期压力与所述分离离合器的测量压力之间的差值来调整所述模型。
