1. A dual-motor electrical transmission for an electrical vehicle, the transmission comprising:
a first and a second electric motor for driving the vehicle;
a first gear arrangement, a second gear arrangement, a summation box, and a control unit, wherein
the first gear arrangement comprises a first gear arrangement first shaft and at least a first gear and a second gear, wherein each of the first and the second gears can be selectively engaged and disengaged with the first gear arrangement first shaft via a first and second clutch element, and the first gear arrangement is configured to supply a first torque from the first electric motor via one of the first and second gears to the summation box;
the second gear arrangement comprises a second gear arrangement first shaft and at least a second gear arrangement first gear, wherein the second gear arrangement first gear can be engaged and disengaged with the second gear arrangement first shaft via a second gear arrangement first clutch element, and the second gear arrangement is configured to supply a second torque from the second electric motor to the summation box;
the summation box is configured to combine the first and second torques and to output a combined output torque; and
the control unit is configured to control the second electric motor to provide an increased second torque during a gear shifting process in the first gear arrangement such that the combined output torque is basically constant during the gear shifting process.
