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.

Description

technical field [0001] The present invention relates to a torque vectoring device, and more particularly, the present invention relates to a torque vectoring device controlled to operate in at least a first mode and a second mode. Background technique [0002] In modern four-wheeled vehicles, such as cars, electric motors can provide an alternative to conventional internal combustion engines and provide additional control over drive torque distribution through so-called torque vectoring. [0003] With the electric motor providing the drive torque, the electric propulsion motor can be set up as the sole drive unit of the vehicle, or connected in series or parallel with the internal combustion engine, resulting in a so-called hybrid vehicle. [0004] An example of a drive combination comprising an electric drive motor and a torque vectoring motor is disclosed in WO2010101506 by the same applicant. [0005] Today, the electrical system of passenger cars is based on 12V. Due t...
