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 computer control system needs the front drive shaft to turn, so that it can monitor and compare the rotational speed of both the front and rear drive shafts. If the rear drive shaft starts to turn faster than the front, the system interprets that (along with input from other sensors) as traction loss.
The computer operated control rods in a nuclear power station provide an active safety system, whereas a fuel that produces less heat at abnormally high temperatures constitutes a passive safety feature; Collision avoidance systems in a modern car
The terms "active" and "passive" are simple but important terms in the world of automotive safety. "Active safety" is used to refer to technology assisting in the prevention of a crash and "passive safety" to components of the vehicle (primarily airbags, seatbelts and the physical structure of the vehicle) that help to protect occupants during a crash.
If this occurs, the hacker can then control the vehicle, putting the safety and privacy of the driver and passengers in jeopardy. Many devices are being designed to help protect drivers' private information along with the safety of their vehicle technology, and the NHTSA is working closely with engineers to develop this future technology.

An active rollover protection (ARP), is a system that recognizes impending rollover and selectively applies brakes to resist. [1]ARP builds on electronic stability control and its three chassis control systems already on the vehicle – anti-lock braking system, traction control and yaw control.
While conventional traction control systems at the time featured only a slip control function, Mitsubishi's TCL system had an active safety function, which improved course tracing performance by automatically adjusting the traction force (called "trace control"), thereby restraining the development of excessive lateral acceleration while turning.
