What are different sensors used to deploy airbags in the car and explain their role in the operation?
The sensors relay signals to the airbag control unit, which analyzes the data and can orchestrate safety features like seat belt lock, automatic door locks, as well as airbag deployment. Two types of airbag sensors used in cars are electrical and mechanical. Electrical sensors vary in design.
How does the airbag system work in a car crash?
Airbag deployment has saved thousands of lives through the years. But how exactly do they work? The airbag system is extremely complex and needs to activate within milliseconds after a crash occurs to ensure the protection of the driver and passengers. What Are Airbags?
Can a mechanical airbag sensor be deactivated?
Since a mechanical sensor does not require a power source, it cannot be deactivated like an electrical sensor can when the battery is disconnected.
How does an accelerometer trigger an airbag?
If the deceleration is great enough, the accelerometer triggers the airbag circuit. Normal braking doesn’t generate enough force to do this. The airbag circuit passes an electric current through a heating element (a bit like one of the wires in a toaster ).
How can you tell if your car has a faulty airbag?
If the vehicle does not have an airbag indicator light there is no real way of knowing if the vehicle has a faulty airbag. If the airbag light comes on, it is best to have the vehicle checked out by a professional.
How does an airbag sensor work in a car?
Your car has a number of airbag sensors, which can basically tell when the vehicle has been involved in an accident by sensing rapid deceleration. It can distinguish dangerous from non-dangerous collisions, and communicate with the airbag system to tell it whether or not to activate the airbags.
Why does my airbag light keep coming on?
Faulty airbag sensors are probably the most common cause of airbag lights coming on. Your vehicle has a number of different sensors which are designed to activate the airbag system in the event of an accident. Naturally, these can become faulty, which would cause the airbag light to illuminate.
How does an air bag work in an accident?
When accident happens, the air bag will operate and reduce most of the damage for driver and other people on car. Yet many drivers do not know airbag deployment conditions nor its operation to deploy. In this article, we will tell you more about how air bag system works and in what exact conditions airbag would deploy.
What to do if your airbag sensor is not working?
It may self-correct once the battery is fully charged again, if not, you may have to perform a sensor reset. If you’ve recently driven through floodwaters, or accidently left the window open in the rain, chances are the airbag module that sits under the driver’s or passenger’s seat got wet.
