Abstract:
A system and method for controlling a motor of an electric drivetrain having a multi-speed transmission with at least a first clutch and a second clutch. The system and method includes initiating a transmission shift requiring engagement of the first clutch, applying synchronizing torque commands to the motor based on an engagement parameter of the first clutch until the shift is complete, and applying non-shifting torque commands to the motor after the shift is complete.
