TRW Automotive Holdings’ second-generation scalable airbag control unit (ACU) is designed for the growing low-cost vehicle and emerging markets. Using a standardized mechanical design including the connector, the ACU can 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. Configured for cost-effective frontal crash protection with one to four squib outputs and no satellite interfaces, the standard ACU also provides the flexibility to be upgraded for use in an enhanced safety system. The enhanced ACU supports up to 12 squibs and four satellite interfaces to provide front- and side-impact detection and protection.
