Multi-speed electric vehicle power-on upshift control

A method for multi-speed electric vehicle power-on shift control, comprising:

• displacing an accelerator pedal;
• detecting a shift event for a multi-speed gearbox adapted to receives a first motor torque from a first electric motor and outputs a first axle torque to a first axle, wherein the multi-speed gearbox includes a plurality of actuatable clutches for effectuating a gear ratio change;
• determining a percentage of accelerator pedal travel when the shift event is detected;
• retrieving a clutch calibration, a first electric motor calibration, and a second electric motor calibration correlating with the determined percentage of accelerator pedal travel;
• applying the clutch calibration in actuating the plurality of actuable clutches to effectuate the gear change ratio and applying the first electric motor calibration in modulating the first electric motor, wherein the actuating of the plurality of actuable clutches and the modulating the first electric motor generates a first axle torque oscillation in the first axle;
• and
• applying the second electric motor calibration in modulating the second electric motor to generate a second axle torque oscillation effective to compensate for the first axle torque oscillation in the first axle to reduce a vehicle acceleration oscillation of the electric vehicle.

A method for multi-speed electric vehicle shift control for damping an acceleration oscillation of the electric vehicle, comprising:

• determining a percentage of accelerator pedal travel;
• retrieving a clutch calibration, a first electric motor calibration, and a second electric motor calibration correlating with the determined percentage of accelerator pedal travel;
• applying the clutch calibration in actuating a clutch-to-clutch gear ratio change, thereby generating a vibration fluctuation in a first axle;
• applying the first electric motor calibration in modulating a first electric motor to dampen the vibration fluctuation, thereby generating a first axle torque oscillation;
• the second electric motor calibration in modulating the second electric motor in generating a second axle torque oscillation sufficiently out-of-phase with the first axle torque oscillation to dampen the acceleration oscillation of the electric vehicle.
