Autoliv introduces the next generation safety control system

October 28, 2011 // By Christoph Hammerschmidt
Automotive safety technology supplier Autoliv has developed a system that combines the controls for vehicle brakes with the controls for vehicle restraints.

Autoliv's combined brake control system can provides key safety functions such as Electronic Stability Control (ESC), Anti-lock braking (ABS) and Traction control (TCS). A study performed by United States Insurance Institute for Highway Safety (IIHS) concluded that ESC reduces the likelihood of all fatal crashes by 43%, fatal single-vehicle crashes by 56% and fatal single-vehicle rollovers by 77-80%.

Already in 2008, Autoliv was the first company to integrate the ESC inertial sensors with the control electronics for airbags and other restraint systems. Now the Swedish company said it plans to integrate not only the inertial sensors, but also the control logic for the brake and restraint control systems. The approach thus combines the controls of the two main life-saving technologies, available in modern vehicles: stability and restraints systems. The move promises provides significant savings to vehicle manufacturers and enhanced performance compared to separate systems, the company said.

Autoliv plans to further drive integration to higher levels. The goal is to develop a single, comprehensive Safety Domain Controller that coordinates all the safety systems in a vehicle, explained David Scroggie, Autoliv Senior Director Motion Control Systems.

“This paves the way for new enhancements of the safety system. For instance, by using signals from our radar, vision and night vision systems, we can improve the performance of both the restraint system and the motion control of the vehicle", Scroggie said.
