The invention provides hybrid vehicle control with rate limited energy management torque. A system and method for controlling a hybrid vehicle having an engine and a traction motor includes operating the engine at an operating point selected based on system efficiency; operating the electric machine to provide an electric machine torque in response to a difference between a driver demand torque and an engine torque associated with the operating point; and limiting a rate of change of the motor torque in response to the rate of change of the driver demand torque. The motor torque rate limit may continuously vary in response to a rate of change in driver demand torque and whether the driver demand torque is increasing or decreasing.

    本公开提供了“具有速率受限的能量管理扭矩的混合动力车辆控制”。一种用于控制具有发动机和牵引马达的混合动力车辆的系统和方法包括:在与基于系统效率选择的操作点处操作所述发动机;响应于驾驶员需求扭矩与和所述操作点相关联的发动机扭矩之间的差值而操作所述电机以提供电机扭矩;以及响应于所述驾驶员需求扭矩的变化速率而限制所述电机扭矩的变化速率。电机扭矩速率限制可以响应于驾驶员需求扭矩的变化速率以及所述驾驶员需求扭矩是在增加还是在减少而连续变化。
