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 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 >
As of 2015, BMW recalled thousands of 2002 and 2003 BMW 3 Series and M3s vehicles. The automaker first conducted limited recalls for the 2001 through 2005 BMW 325xi, 330xi, and 2001 through 2006 325 Ci and 330Ci cars registered in Hawaii, Florida, Puerto Rico and the U.S. Virgin Islands.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 >
