How does vehicle stability control work?
Vehicle stability control was created in cars back in the late 1990s as a way to offer drivers additional assistance with their steering. This is an electronic control system which involves the use of high-tech sensors and the car’s central computer to perform certain mechanical actions while driving. For example, if it is raining outside and the roads get slippery, it can be very easy to veer your car off the road by oversteering or understeering. Oversteering is when you turn the wheel and the car turns more than you wanted it to. Understeering is when you turn the wheel and the car continues to go forward rather than turn in the direction you wanted it to. Vehicle stability control will correct these problems before they occur.

The vehicle stability control system of your car works in conjunction with its traction control and anti-lock brakes to stabilize the car properly. You’ll find the vehicle stability control system in the central location of your vehicle. Its job is to detect when your car does not turn far enough or when it turns too far. In other words, it compares the direction your vehicle is moving to the direction you turned the wheel. Once it detects a difference between the direction you move and the direction you turned the wheel, the stability control system will send a signal to the brakes to control the throttle and slow down the car. That way the originally desired turn will be able to be sustained without any failure.
There are three types of sensors that the stability control system uses to make this all happen. The wheel-speed sensor is one type of sensor that is located in each of the vehicle’s wheels. These sensors measure the speed at which the vehicle is traveling and then sends the information back to the computer. From there, the computer compares this speed to the speed of the engine. The steering-angle sensor is another type of sensor which calculates the direction in which the wheel is being turned. If the sensor detects you are traveling in a different direction then the stability control will activate. Finally, the rotational-speed sensor measures the motion of the car from each side.
If you live in snowy, rainy or icy conditions, then you need to have stability control in your vehicle or else the chances of you getting into an accident will increase. Chances are you probably already own a car that has this system in it but make sure you double check anyway.
