控制车辆动力传动系的方法
摘要：
本发明提供一种控制车辆动力传动系的系统和方法。所述系统和方法在瞬时事件期间设定所需的变速器输入扭矩。组合式地设定所需的牵引电动机扭矩和所需的发动机扭矩以满足所需的变速器输入扭矩。所述系统和方法包括：估计在瞬时事件期间提供所需的发动机扭矩时的延迟期间的实际发动机扭矩。基于实际发动机扭矩和所需的变速器输入扭矩之间的差异来命令瞬时牵引电动机扭矩。命令的瞬时电动机扭矩对提供所需的发动机扭矩时的延迟进行补偿，从而防止瞬时事件期间的扭矩扰动。
摘要（英）：

A system and method for controlling a vehicle powertrain is provided. The system and method sets a required transmission input torque during a transient event. A required traction motor torque and a required engine torque, in combination, are set to fulfill the required transmission input torque. The system and method includes estimates an actual engine torque during a delay in providing the required engine torque during the transient event. A transient traction motor torque is commanded based on a difference between the actual engine torque and the required transmission input torque. The commanded transient motor torque compensates for the delay in providing the required engine torque in order to prevent torque disturbances during the transient event.
