The present disclosure provides control and methods for calculating clutch torque including seal friction. A hybrid vehicle includes an engine, an electric machine, a disconnect clutch configured to selectively couple the engine to the electric machine, and a controller. The controller is programmed to command a target pressure to the disconnect clutch in response to a request to start the engine with the electric machine, the target pressure depending on a seal friction force derived from a measured line pressure of the disconnect clutch and a rate of change of the measured line pressure.
本公开提供了“将密封件摩擦力包括在内来计算离合器扭矩的控制和方法”。一种混合动力车辆包括发动机、电机、分离离合器和控制器,所述分离离合器被配置为将所述发动机选择性地联接到所述电机。所述控制器被编程为响应于用所述电机起动所述发动机的请求,向所述分离离合器命令目标压力,所述目标压力取决于从所述分离离合器的测量的管线压力和所述测量的管线压力的变化率得出的密封件摩擦力。
