Abstract
A system includes an engine, a motor and a transmission coupled to the engine and the motor and that can be shifted from a first gear ratio to a second gear ratio. The system also includes an ECU that may receive or generate a shift command corresponding to an instruction for the transmission to shift from the first gear ratio to the second gear ratio and may determine a target engine speed corresponding to a desired speed of the engine when the transmission shifts from the first gear ratio to the second gear ratio. The ECU may control the motor to adjust the motor torque such that the motor torque causes the engine speed to become close or equal to the target engine speed and may cause the transmission to shift to the second gear ratio when the engine speed is within a threshold of the target engine speed.
