What is TCS?
TCS stands for Traction Control System and is a safety feature used in cars to maintain the traction between the road and the driven wheels. In the past, driver had to remove his feet odd the accelerator pedal on slippery roads to avoid slipping of the wheels. Today with the help of electronic traction control system, the power from the engine delivered to the wheels can be limited.
When was TCS introduced?
Before TCS, rear wheel drive cars were installed with limited slip differential, a mechanical system that delivers more torque to the non slipping wheel, while still allowing some wheel spin to occur.
In the year 1971, Buick introduced MaxTrac system to detect the rear wheel spin with the help of a computer system. MaxTrac system modulated the engine power to those slipping wheels to provide more traction. Cadillac came up with Traction Monitoring System (TMS) in 1979 on its Eldorado model.
How TCS works?
Electronic Traction Control system makes use of the same wheel speed sensors used for Anti-lock Braking System (ABS). When the TCS system detects that one wheel is rotating slower than the other wheels, it modulates the brake valves to reduce the brake pressure on that particular wheel and avoid slipping. In addition to this, TCS also regulates the engine power delivered to the slipping wheels.
Traction Control System does not increase traction, but only prevents the wheels from slipping by maintaining traction. A vehicle might still get stuck or lose control even with TCS on it. For better protection, a car should feature both TCS and ABS.
The powertrain can reduce the torque supplied to the slipping wheels by cutting off the fuel supply, limiting throttle action, retarding spark ignition, shutting down some cylinders, and many other methods.
Traction Control can also help in cornering. If too much throttle is supplied, then the wheels might lose traction and slip sideways. TCS limits the power supplied to those wheels and thus help in increasing the grip of the tires.
