The invention relates to an electrified powertrain with a maximum performance mode control strategy using extended inverter limits. A method controls an electrified powertrain having a traction motor and a traction power inverter module (TPIM). The controller determines current component capabilities and usage of the electrified powertrain. In response to the current component capability being less than a capability threshold and the usage matching a predetermined approved usage, the controller determines whether a predetermined margin exists in the component capability for operating the electrified powertrain in a maximum performance mode (MPM) throughout the duration of the enhanced driving maneuver. When there is a predetermined margin, the controller temporarily applies an Extended Inverter Limit (EIL) of the TPIM to enable the MPM. The EIL allows operation of the traction motor to occur above default torque and speed operation limits throughout the duration of the enhanced driving maneuver. The MPM/EIL availability is communicated to an operator.
本发明涉及具有使用扩展逆变器限制的最大性能模式控制策略的电气化动力总成。一种方法控制具有牵引电动机和牵引功率逆变器模块(TPIM)的电气化动力总成。控制器确定电气化动力总成的当前部件能力和使用情况。响应于当前部件能力小于能力阈值,并且使用情况与预定的批准使用情况匹配,控制器确定在部件能力中是否存在预定裕度,以用于在增强的驾驶操纵的整个持续时间内在最大性能模式(MPM)中操作电气化动力总成。当存在预定裕度时,控制器暂时应用TPIM的扩展逆变器限制(EIL)以启用MPM。EIL允许牵引电动机的操作在增强的驾驶操纵的整个持续时间内高于默认的扭矩和速度操作限制发生。MPM/EIL可用性被传达给操作者。
