用于控制车辆动力传动系的系统和方法
摘要：
一种用于控制车辆动力传动系的系统和方法，所述车辆动力传动系包括可操作以推进所述车辆的发动机和马达，所述方法包括：响应于减速请求而使马达的扭矩以第一扭矩减小速率从高于最小马达扭矩的扭矩水平减小。响应于所述减速请求而使发动机的扭矩以小于第一扭矩减小速率的第二扭矩减小速率减小。
摘要（英）：

A system and method for controlling a vehicle powertrain including an engine and a motor operable to propel the vehicle includes reducing a torque of the motor at a first torque reduction rate from a torque level above a minimum motor torque in response to a deceleration request. A torque of the engine is reduced at a second torque reduction rate less than the first torque reduction rate in response to the deceleration request.
