The Autoliv Gtw.Mod. B0110 627697900B is a specialized gateway communication module manufactured by Autoliv, a global leader in automotive safety systems. This module acts as a critical data router within a vehicle's passive safety network, facilitating reliable and high-speed communication between various safety system components, such as sensors and control units.
In a modern vehicle's safety system, multiple satellite sensors (e.g., front, side) need to communicate their status and crash data to the central safety electronic control unit (ECU) in real-time. The Autoliv Gtw.Mod. B0110 627697900B is deployed as a central communication node. It aggregates data from these distributed sensors via a high-speed bus (e.g., PSI5 or ASRB), performs necessary protocol processing, and ensures the robust and timely delivery of critical information to the main airbag control unit. This application solves the pain points of data integrity, network latency, and reliability, which are paramount for making correct deployment decisions within milliseconds during a collision event.
