Autoliv B0760 627913600B Controller Module
Overview
Autoliv B0760, part number 627913600B, is a 6U VME‑bus SRS restraint‑system simulation controller board developed by Autoliv, engineered specifically for bench‑based development of Airbag Control Units (ACU).This module is laboratory‑grade test hardware rather than an on‑vehicle production airbag ECU. It virtually simulates real‑vehicle firing circuits, acceleration sensor signals, temperature signals and switch signals, and supports fault injection. It enables full‑condition validation of airbag controllers without physical pyrotechnic airbag initiators, lowering crash‑test risks and test costs. Operation requires pairing with the B0110 gateway module, a VME chassis and dedicated host‑PC software.
Core Functions
- Airbag firing circuit simulation: Simulates equivalent loads for driver‑side and passenger‑side airbags, side curtain airbags and seat‑belt pretensioner initiators. It can simulate open‑circuit, short‑circuit and impedance‑shift faults to validate ACU diagnostic strategies.
- Dynamic sensor waveform simulation: Outputs crash acceleration waveforms; supports playback of NCAP standard crash waveform libraries and import of custom waveforms to reproduce various impact conditions. It is also compatible with RTD temperature signals, digital switch signals and pulse signal simulation.
- Fault‑injection testing: Implements channel disconnection, short‑to‑ground / short‑to‑supply, signal offset and CAN message tampering for FMEA failure‑mode validation.
- Electrical isolation protection: Independent isolated drivers for each signal channel with 3000 VAC isolation withstand voltage. Resists bench‑level EMI interference and protects the unit‑under‑test airbag control unit.
- On‑board waveform storage: Local flash memory stores multiple sets of crash‑condition waveforms, enabling one‑click recall via host PC software and compatibility with automated batch‑test scripts.
- System‑level coordinated operation: Communicates with the B0110 gateway via the VME backplane. The gateway handles CAN/LIN bus forwarding while the B0760 generates analog signals, forming a complete SRS test system.
