ELECTRIFIED POWERTRAIN WITH MAXIMUM PERFORMANCE MODE CONTROL STRATEGY USING EXTENDED INVERTER LIMIT

A method controls an electrified powertrain having an electric traction motor and a traction power inverter module (TPIM). A controller determines a current component capability and use case of the electrified powertrain. In response to the current component capability being less than a capability threshold and the use case matching a predetermined approved use case, the controller determines whether a predetermined margin exists in the component capability for operating the electrified powertrain in a maximum performance mode (MPM) for a full duration of a boosted driving maneuver. When the predetermined margin exists, 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 operating limits for the full duration of the boosted driving maneuver. MPM/EIL availability is communicated to the operator.
