New Car Info - Research in the USA showed a significant effect on ESC reduces the risk of fatal single accident and more than one car. Works very well in the SUV. But the system is also criticized.
ESC Electronic Stability Control (ESC) is designed to help drivers to maintain control of his vehicle at high speed maneuvers or on slippery roads. Usually the condition is causing symptoms of oversteer or understeer. ESC applies the brakes and engine control to control the car remained on track.
Research in the USA in 2004 showed significant effects of ESC reduces the risk of fatal single accident. Researchers from the Insurance Institute of Highway Safety (IIHS) reinforce the results of 2004 research by showing that ESC reduces the risk of fatal up to 32% on inter-vehicle accident.
The study also confirmed on a single accident ESC can reduce the risk of fatal to more than 40%. The researchers estimate that if all cars equipped with ESC, then 10.000 fatalities on the streets of the USA could be avoided each year.
"This discovery indicates the ESC should be standard on every vehicle," said Susan Ferguson, senior vice president for research institutions. "Jaranrg is a safety technology that shows the effect is so great in reducing fatal accidents."
In the USA, currently 40% of passenger vehicle output in 2006 is equipped with ESC as standard equipment and 15% offer it as optional. ESC became standard in every model Audi, BMW, Infiniti, Mercedes-Benz and Porsche output 2006. Cadillac, Jaguar, Land Rover, Lexus, Mini, Toyota, Volkswagen and Volvo also offers on each model, at least optional.
In Indonesia, the car-mobi premium is usually already equipped with this device. It could be that price considerations lead to the ESC is not installed in most cars. In the USA as the ESC is offered between $ 300 - $ 800 as a single system. When equipped with other features the price quickly rose above $ 1,000.
ESC is offered by many names, almost every brand has its own version and name of each, such as Electronic Stability Program (DaimlerChrysler, Hyundai, Jeep, Kia, Peugeot, Renault, VW), Dynamic Stability Control (BMW), Electronic Stabilization Program (Audi), and Vehicle Dynamic Control (Nissan).
How ESC works
ESC Working Method ABS brakes have speed sensors and a number of ESC adds sensors that continuously monitor how well a vehicle responds to input from steering wheel. These sensors can detect when the driver lost control because the car deviated from the path that should be passed, the problems that often arise in high-speed maneuvers or slippery-road. In this situation, the ESC automatically brakes individual wheels to keep the car under control. When the driver suddenly do a maneuver, such as 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 so the car under control.
ESC was first introduced by Robert Bosch GmbH, leading German automotive components company. This system called Elektronisches Stabilite tsprogramm (ESP) which was first used 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 its version respectively.
ESC is relatively new. Just a few years ago researchers had sufficient data to analyze their effects on actual accidents. Using data Fatality Analysis Reporting System and police reports about accidents in 10 states between 2001-04, IIHS crash rate compared to sedans and SUVs (same model) that uses the ESC and no.
ESC known to provide a greater benefit compared to sedans to SUVs. Single accident risk reduction for the SUV reached 49% compared to 33% for sedans. Many single accident also makes the car overturned. Effectiveness of ESC prevent rollover is very dramatic. ESC reduces the risk of the SUV rolled up to 80% and 77% sedan.
Critics ESC
However, ESC is also criticized for a number of drivers feel features restrict exploration of the dynamic behavior of the driver of their car. ESC 'rob' them pleasure driving, he said. Therefore, some automotive companies offer a system where the driver can choose to eliminate the function of ESC. Others add to the tolerance limit oversteer or understeer before the ESC menginterverensi. There are also drivers who modify their ESC.
Another criticism, because it uses the ESC, there are drivers who felt able to drag as he pleased when passing the bend, past the limits ditoleriri car or ESC system. When this happens, the car will be slammed with a very loud and pose a greater danger.
