Today, sensors are widely used in automobiles, and they have a growing number of uses. A significant driver of sensor growth in the automotive market has been and will continue to be the rising demand for durable and trustworthy car safety systems.
The primary automotive application for inertial sensors is crash sensing for airbag control. An accelerometer is used in these applications to continuously measure the car’s acceleration.
A microcontroller calculates the integral of the acceleration when this parameter exceeds a preset threshold to see if a significant change in velocity has taken place.
The airbag is fired if it has. Because the car door is closer to the occupant than the steering wheel or dashboard, the choice to deploy side airbags must be made even faster.
The Global Automotive Acceleration Satellite Market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2026, registering a CAGR of XX% from 2022 to 2027.
Continental AG’s gSAT decentralized acceleration satellite sensor for all-around protection: in a crash, the intelligent crash sensors are the ideal complement to the airbag control unit. In the event of a collision, the acceleration satellites gSAT provide further support.
They measure and send information to the airbag control unit about the acceleration values in stiff vehicle structures. In milliseconds, the airbag control unit can evaluate both the duration of the intrusion and the severity of the accident, and activate lifesaving restraint systems.
A dual-channel, high-g accelerometer satellite sensor from Bosch with a PSI5 interface is used in airbag systems. The sensor provides frontal or side impact information for airbag systems. The same 2-wire connection is used to handle both power and digital communication.
