在混合电动车辆中提供电动机转矩储备的方法
摘要：
一种操纵车辆动力系系统的方法，所述方法包括：通过执行将预定的最大发动机输出转矩降低到一个最大储备电动机输出转矩和将最小发动机输出转矩升高到一个最小储备电动机输出转矩的至少一个来建立一个电动机机转矩储备，其中最大储备电动机输出转矩和最小储备电动机输出转矩都是用来分别取代预定的最大发动机输出转矩和预定最小发动机输出转矩，以便确定至少一个变速器控制参数的许可控制点的范围。电动机转矩储备可以包括一个静态电动机转矩储备、一个动态电动机转矩储备，或者静态和动态转矩储备的组合。动态转矩储备可以包括一个预期动态储备、一个反应动态储备或预期动态储备与反应动态储备的组合。
摘要（英）：

A method of operating a vehicle powertrain system comprising an electric motor and transmission where the electric motor is operably and selectively coupled to the transmission and adapted to provide an output torque contribution thereto, and the electric motor has a predetermined maximum motor output torque and a predetermined minimum motor output torque which are used to determine a range of permissible control points for at least one transmission control parameter. The method includes establishing a motor torque reserve by performing at least one of decreasing the predetermined maximum motor output torque to a maximum reserved motor output torque and increasing the minimum motor output torque to a minimum reserved motor output torque, wherein the maximum reserved motor output torque and the minimum reserved motor output torque are used in place of the predetermined maximum motor output torque and the predetermined minimum motor output torque, respectively, to determine the range of permissible control points for the at least one transmission control parameter.
