What is a car’s torque vectoring system and how does it work?

, , , ,

A car’s torque vectoring system is a technology that improves a vehicle’s stability and handling by controlling the distribution of power between its wheels. This system uses different methods to achieve the desired outcome but, essentially, torque vectoring is all about individually controlling the speed of each wheel.

One of the most common ways to achieve this is by using a differential that can distribute torque between the left and right wheels. A limited-slip differential can sense if one of the wheels is slipping and send more torque to the wheel with more traction, improving traction and stability during acceleration, cornering, and braking.

Another way to achieve torque vectoring is through a system that can selectively apply brakes to specific wheels. This method is called brake-based torque vectoring, and it can help to distribute torque and reduce understeer or oversteer during cornering.

Finally, some vehicles use an all-wheel-drive system or electric motors to directly control the torque delivered to each wheel, achieving much faster and more precise control over the car’s power delivery, improving vehicle performance and handling.

In summary, the torque vectoring system is all about controlling how much torque is sent to each wheel to improve stability, handling, and traction on the road. The system uses different methodologies, including the application of brakes, the use of all-wheel-drive system or electric motors, and the use of limited-slip differentials, depending on the vehicle’s manufacturer and model.
