Torquevectoringis a technology employed in automobile differentials that has the ability to vary thetorqueto each half-shaft with an electronic system; or in rail vehicles which achieve the same using individually motored wheels.
The possibility of independently controlling thetorqueon each wheel quickly and precisely makes applyingTorqueVectoringControl (TVC) strategies easy. Indeed,TorqueVectoring(TV) consists in applying different longitudinal forces to the wheels of the same axle, resulting in a yaw moment that is used to control the vehicle lateral dynamics.
Torquevectoringaims to improve steering response and handling through the distribution oftorquebetween the wheels. At first glance, this may seem similar to what limited-slip differentials (LSD) do. However,torquevectoringis a more advanced technology. Perhaps the best way to differentiate ...
Through already made simulation-based analysis, this paper quantifies and compares the impact of various ITVC methods on key vehicle performance metrics, such as yaw stability, lateral acceleration, and energy consumption (kWh), of vehicle with and withouttorquevectoring.
The difference between these values indicates the adjustment thattorquevectoringshould apply to achieve the target response. Enhancing Eq. 1 with the vehicle parameters and incorporating thetorquevectoringcontribution, the yaw moment generated by the real vehicle is described by equation:
