Signals from the vertical acceleration sensor, the horizontal acceleration of the vehicle, sensors and wheel speed ... were collected to determine the actual state of motion. The computer compares the results with the steering wheel angle from which the brake command control, or reduce engine power, fast car is taken according to the desired state of the driver.
Electronic balancing system incorporated with the antilock brake system allows ABS-independent ESC brake each wheel individually. Any vehicles which are equipped with electricity as the brakes are equipped with ABS, but a car with ABS is unlikely to have ESC.
Balance electronic modules using hydraulic control similar to the ABS. But between the two systems still differ, only the ABS car, the control module can only function hydraulic control or reduce brake pressure effects on brake cylinder. For vehicles equipped with ESC than two functions on the module can increase the hydraulic oil pressure to the area needed to be asked to create a braking force difference between the wheels.
Because of inseparable elements that many people confuse the functions and working principles of the ESC and ABS. Antilock brake system works when the driver brakes, wheels hardware bundle at risk. State control system to work when there is a difference between steering angles and angles of the vehicles. This means that ESC works completely automatically.
You imagine on a sunny day you drive on a familiar path. Today, on the road appeared a bunch of big oil. Seemingly harmless, you drive into the app as usual crab. Suddenly the car suddenly spins, wheels losing traction, centrifugal force as the car was thrown, hundreds of thousands of bad things can happen then. A car going the opposite direction occurs, or sex of the lane across the abyss ...
But if you go car equipped with electronic weighing systems things will happen in the other direction. As soon as the body tends to be turned or thrown by centrifugal force of inertia for reduced traction. ESC automatically reduces engine power and braking the appropriate wheel. Thus moving vehicle remains stable.
But there are cases where electronic balancing system becomes incapacitated. That's when the roads too slippery, or excessive tire wear or improper vapor pressure standard reduces traction.
By the irreplaceable role of the car manufacturers spend considerable time in favor of the research and development system. Each company has different names, such as the principle of operation is not much different.
Toyota, Suzuki often called control system dynamics VSC (Vehicle Stability Control), Mercedes, Audi, Volkswagen and Hyundai to name this system is the electronic stability program ESP (Electronic Stability Program). System VSA (Vehicle Stability Assist) of the Honda, VDC (Vehicle Dynamic Control) of Nissan or ASC (Active Stability Control) Mitsubishi's also a similar function.
