The predecessor of modern electronic traction control systems can be found in high-torque, high-power rear-wheel-drive cars as a limited slip differential.A limited-slip differential is a purely mechanical system that transfers a relatively small amount of power to the non-slipping wheel, while still allowing some wheel spin to occur.
Traction control system (TCS) helps prevent traction loss in vehicles and prevent vehicle turnover on sharp curves and turns. [47] By limiting tire slip, or when the force on a tire exceeds the tire's traction, this limits power delivery and helps the driver accelerate the car without losing control. [47]
The ECM is a type of electronic control unit (ECU), which is an embedded system that employs software to determine the required throttle position by calculations from data measured by other sensors, including the accelerator pedal position sensors, engine speed sensor, vehicle speed sensor, and cruise control switches.
Electronic stability control (ESC), also referred to as electronic stability program (ESP) or dynamic stability control (DSC), is a computerized technology [1] [2] that improves a vehicle's stability by detecting and reducing loss of traction . [3]
These motors providing a maximum power of 2700 kW are controlled in order to adjust their speeds when cornering, thus increasing traction and reducing tire wear. The Eliica is also equipped with electronic differential; this eight-wheeled electric vehicle is capable of driving up to 370 km/h whilst maintaining perfect torque control on each wheel.

However, active safety is increasingly being used to describe systems that use an understanding of the state of the vehicle to both avoid and minimise the effects of a crash. These include braking systems, like brake assist , traction control systems and electronic stability control systems, that interpret signals from various sensors to help ...
A special transmission unit was used in the experimental 2014 car MUTE of the Technical University of Munich, where the bigger motor is providing the driving power and the smaller for the torque vectoring functionality. The detailed control system of the torque vectoring is described in the doctoral thesis of Dr.-Ing. Michael Graf. [14]
