Restraint Control System

The Restraint Control System is the core of a vehicle’s passive safety concept. Acceleration and pressure sensors detect vehicle crashes. An Airbag Control Unit hosts all features for impact protection (Airbag firing, seatbelt pretensioning) and provides a number of other, safety- and homologation relevant features, such as the Event-Data-Recorder and seat-belt-reminders.

Restraint Control System – Feature Overview

The following features can be realized by our Restraint Control System. All listed features are compliant with the upcoming General Safety Regulation requirements. As such, the Airbag Control Unit is a key enabler for vehicle legislation.

  • Front Crash detection
  • Side Crash detection
  • Rear Crash detection
  • Rollover detection
  • Warning Lamp
  • Event Data Recorder
  • Energy Reserve
  • Internal Sensors
  • Crash Output (CAN/PWM)
  • Seat Belt Reminder

Restraint Control System – Hardware Overview

Airbag Control Unit

The safety computing unit hosts all features of the safety restraint system. It supports up to 12 satellite sensors and additional 5 analogue inputs, e.g. from seat track sensors.
