LIVONIA — TRW Automotive Holdings Corp. (NYSE: TRW) is developing its second generation scalable airbag control unit (ACU) designed for the growing low-cost vehicle and emerging markets.
The system allows the ACU to be adapted within a vehicle platform to offer two options — standard and enhanced — for models sold within emerging territories and also for those exported to developed markets.
“We continue to seek ways to ensure that all vehicles can be equipped with advanced safety equipment,” said Ed Carpenter, vice president of TRW Electronics. “Our second generation scalable ACU offers emerging market OEMs the opportunity to fit their vehicles with advanced safety equipment and the new units will include the option to integrate the inertial measurement unit into the ACU to sense vehicle yaw, a key technology for the growing electronic stability control market.”
The standard ACU is configured for cost-effective frontal crash protection with one to four squib outputs and no satellite interfaces, but provides the flexibility to be upgraded for use in an enhanced safety system.
The enhanced ACU supports up to twelve squibs and four satellite interfaces to provide front and side impact detection and protection, and is designed to handle the additional functional requirements to meet European and / or North American safety requirements. This includes the option to add an inertial measurement unit to support active safety systems such as ESC.
With the updated design, costs have been further reduced for the enhanced ACU variants with 8 squibs or more, providing vehicle manufacturers greater flexibility and competitiveness. To reduce tooling and engineering costs and design complexity further, the scalable ACU family uses a standardized mechanical design including the connector. This enables economic production of ACUs even for relatively small OEMs with low volume platforms and/ or low airbag fitment rates.
TRW is leading the way in the performance/price ratio with this second generation airbag controller, fulfilling the need for cost effective ACUs not only for value oriented manufacturers but also for emerging markets including Brazil, Russia, India and China. The Company envisions that the technology will be ready for production by 2014.
With 2011 sales of $16.2 billion, TRW Automotive ranks among the world’s leading automotive suppliers. Headquartered in Livonia, the company operates in 26 countries and employs over 60,000 people worldwide. TRW Automotive products include integrated vehicle control and driver assist systems, braking systems, steering systems, suspension systems, occupant safety systems (seat belts and airbags), electronics, engine components, fastening systems and aftermarket replacement parts and services.
