The present disclosure provides a system and method for controlling engine torque. Methods and systems are provided for controlling engine torque of an engine of a vehicle. The method includes determining a drive torque demand on a crankshaft of an engine; determining an accessory torque demand on the crankshaft, the accessory torque demand including a first torque demand from a first electric machine and a second torque demand from a second torque; determining whether a sum of the drive torque demand and the accessory torque demand is greater than an available torque capacity output from the engine crankshaft; and in response to determining that the sum of the drive torque demand and the accessory torque demand is greater than the available torque capacity output from the engine crankshaft, increasing a speed of the engine.

    本公开提供了“用于控制发动机扭矩的系统和方法”。提供了用于控制车辆的发动机的发动机扭矩的方法和系统。所述方法包括:确定发动机的曲轴上的驱动扭矩需求;确定所述曲轴上的附件扭矩需求,所述附件扭矩需求包括来自第一电机的第一扭矩需求和来自第二扭矩的第二扭矩需求;确定所述驱动扭矩需求和所述附件扭矩需求的总和是否大于来自所述发动机曲轴的可用扭矩容量输出;以及响应于确定所述驱动扭矩需求和所述附件扭矩需求的所述总和大于来自所述发动机曲轴的所述可用扭矩容量输出,增加所述发动机的转速。
