Airbag and Crash Detection

Overview

NXP enables passive vehicle safety features such as crash detection to maintain driver and passenger safety.

NXP sensors and MCU, developed following ISO26262 standard, monitor vehicle acceleration variation and help deploy airbags in case of a collision. Multiple accelerometers detect abrupt changes in acceleration. An integrated IC helps transmit data from remote sensors to the main electronic control unit (ECU). NXP also offers multiple solutions for ECU power management, designed to meet airbag application requirements.
