Abstract
A torque vectoring device for a vehicle is provided, comprising an electrical motor (110) being connected to a differential mechanism (20) via a transmission (120), wherein the torque vectoring device further comprises at least one control means (130, 150) for changing the torque path of the transmission (120) between a first mode, in which the transmission connects the electrical motor (110) to the input shaft of the differential mechanism (20) for hybrid drive mode, and a second mode, in which the transmission connects the electrical motor (110) to the output shaft of the differential mechanism (20) for torque vectoring mode.
