Airbag and Crash Detection

Overview

NXP enables passive vehicle safety features such as crash detection to maintain drivers and passenger safe in case of collision

NXP sensors and MCU developped following ISO26262 standard monitor vehicle acceleration variation and help deploy airbag in case of detected collision.Multiple accelerometers sense vehicle motion to detect abrupt change in acceleration. An integrated IC helps transmitting data from remote sensor to the main Electonic Control Unit (ECU). An MCU analyse sensor data and enable the control of squib driver to deploy airbag. NXP also offer multipe solution for ECU power management designed to meet airbag application requirement.
