Claim 7:
8. A system for operating an electric vehicle, comprising:
a first motor; and
a transmission coupled to the first motor configured to shift gears when a speed of the electric vehicle crosses a shift threshold, wherein the shift threshold is independent of a position of an acceleration pedal of the electric vehicle, wherein the transmission is configured to perform an upshift in one of a first mode when the position of the acceleration pedal is less than a first pedal threshold, a second mode when the position of the acceleration pedal is greater than the first pedal threshold and less than a second pedal threshold, and a third mode when the position of the acceleration pedal is greater than the second pedal threshold, wherein the first mode includes offloading torque entirely from the first motor to a second motor, the second mode includes offloading some but not all torque from the first motor to the second motor, and the third mode includes no offloading of torque.
