ABS brakes have speed sensors and a number of Electronic Stability Control (ESC) adds sensors that continuously monitor how well the vehicle to respond to input from the steering wheel.

Electronic Stability Control

These sensors can detect when the driver lost control because the car deviated from the path that should be passed,-a problem that frequently appears in high speed maneuvers or slippery-road. In this situation, the ESC automatically breaks individual wheels to keep the car under control. When the driver suddenly maneuvering motion, e.g. cornering too fast, lost control of the car at risk then the ESC will conduct a series of braking is required and in some cases also reduce the speed of the car if the car is under control.

ESC was first introduced by Robert Bosch GmbH, a leading German automotive components company. This system called Elektronisches Stabilitts programm (ESP) which was first used by Mercedes-Benz and BMW in 1995. Continental Automotive System and then offer it to a wider market with the name of Electronic Stability Control which later became a generic name, although many automotive manufacturers use a different name for each version.

ESC is relatively new. Just a few years ago the researchers have enough data to analyze its effect on actual accidents. Using data Fatality Analysis Reporting System and police reports about accidents in 10 states at 2001 until 2004, IIHS comparing accident rate for sedans and SUVs (same model) that uses the ESC and no.

ESC is known to provide benefits greater than the sedans to SUVs. Reduction of the risk of a single accident to an SUV achieving 49% compared to 33% for sedans. Lots of single accidents also make the car overturned. Effectiveness of ESC prevent rollover is very dramatic. ESC reduces the risk of SUVs rolled up to 80% and 77% sedan.
