Advanced safety systems to help prevent vehicle rollovers

Livonia, Michigan – TRW Automotive Holdings, a manufacturer of automotive safety systems, is accelerating the integration of advanced active and passive safety technologies to help drivers mitigate vehicle rollovers and protect passengers in the event a rollover occurs. These technologies are particularly valuable for Sport Utilities and other high-center-of-gravity vehicles.

“In the wake of rollover accidents and resulting fatalities, particularly in North America where the light truck market has grown significantly in recent years, TRW continues to pursue advances in vehicle safety systems that help mitigate rollover accidents and their effects,” said Peter Lake, executive vice president, Sales and Business Development for TRW Automotive.

Data collected by NHTSA shows that nearly 90 percent of single-vehicle rollovers occur when a vehicle leaves the roadway, digging its tires into soft soil or striking a curb or guardrail that typically “trips” the vehicle.

To help vehicles remain on the road, TRW Automotive continues to drive the evolution of several active safety technologies:

  • Electronic Stability Control (ESC) – This combines the capabilities of TRW Automotive’s anti-lock braking system and traction control technologies with a lateral stability control feature.

  • Active Suspension Safety Systems – This suite of safety technologies developed by TRW Automotive includes its Active Dynamic Control (ADC) and Semi-Active Roll Control (SARC) systems. The ADC system uses stabilizer bars connected to computer-controlled actuators fitted to the front and/or rear stabilizer bars that use hydraulic pressure to reduce body lean and hold the vehicle flatter during cornering.
  • Cold Gas Rollover Inflator – Should a rollover accident occur, this technology is used in side curtain airbags and was the first inflator on the market to utilize cold gas to inflate the airbag. The combination of cold gas and specially coated curtain airbags allow the bags to stay inflated for up to six seconds to help keep passengers inside the vehicle during a rollover event and assist in mitigating head and other injuries.
