The present disclosure provides methods and systems for increasing available propulsion motor torque during engine startup. Systems and methods for starting an engine that may be started via an electric machine and a driveline disconnect clutch are described. In one example, the method estimates a maximum motor propulsion torque during an engine start. The maximum motor propulsion torque may be based on an estimated speed at which the torque converter impeller speed will be at the end of the engine start-up period.
本公开提供了“在发动机起动期间增加可用推进马达扭矩的方法和系统”。描述了用于起动可以经由电机和传动系分离离合器起动的发动机的系统和方法。在一个示例中,所述方法估计发动机起动期间的最大马达推进扭矩。最大马达推进扭矩可以是基于发动机转动起动时段结束时变矩器泵轮转速将处于的估计转速。
