Airbags deploy when a moderate to severe crash impact triggers the electrical control mechanism that inflates the bags. More advanced airbag computer systems use crash sensors, seat belt sensors, weight sensors in seats and car speed to determine exactly when to deploy.Know More
When triggered, an igniter fires and sets off a chemical reaction that quickly produces a gas that inflates the airbags. Airbags inflate in less than half a second in frontal crashes.
Airbag computers are programmed with must-deploy speed thresholds to ensure that they only deploy when needed to prevent injury. These thresholds take into account readings from sensors. For example, if front passengers are wearing seat belts, the deploy threshold for a frontal crash is approximately 16 mph.Learn more about Car Parts & Maintenance
Airbags, a standard technology in cars, exist as small pieces of material that inflate instantaneously upon sensing an accident or impact; they operate in conjunction with special sensors that signal their inflation to protect occupants. Airbags appear in many locations throughout cars; they are standard on the front seats, and newer cars have them on the back side doors too. Although small, airbags are critical safety features in accidents as they may keep passengers protected from hitting glass, the steering wheel, dashboard and other objects during crashes.Full Answer >
Airbags save lives by rapidly deploying a nylon bag in order to prevent drivers and passengers from impacting hard parts of the vehicle such as the steering wheel and windshield. The aim is to keep occupants from sustaining serious head and upper body injuries. A study published in 2009 by the National Highway Transportation and Safety Administration states more than 28,000 American lives have been saved because of airbag technology.Full Answer >
Airbag control modules from 2007 and on evaluate sensor data and deploy when doing so is less dangerous than injuries from the accident. In general, this threshold is equivalent to hitting a rigid wall at 10 to 12 miles per hour if the occupants are not wearing seat belts.Full Answer >
Some of the most common causes for a car's stalling whilst driving include: a poor idle speed control, or ISC, system, low fuel pressure, loss of ignition and vacuum or EGR leaks. Diagnosing the specific problem should be a priority in order to get it fixed.Full Answer >
