What is torque vectoring and how does it work? Moreover, what is a torque vectoring differential? Well, unlike the traditional mechanical differentials that we’re quite used to seeing, TVD or the torque vectoring differential employs both electronic and mechanical means to determine the distribution of torque.
This particular systems features a pair of multi-plate clutches. The amount of pressure that is applied to the clutches via a small valve is controlled by electric motors. That level of pressure determines the level of torque distributed to each of the rear wheels during deceleration and acceleration.
Now, a torque vectoring differential acts very much like an open differential, expect for the several things. The amount of torque that is sent to each wheels is bigger in when the system features a torque vectoring differential.
In the video below, Engineering Explained takes a differential from a Lexus RCF, the first front engine, rear-wheel drive vehicle to be offered with such a system, and explains what it is and how it works.
