TRW Automotive Holdings Corp. (NYSE: TRW), the global leader in active and passive safety, has launched its latest-generation Electric Park Brake (EPB) technology with three major Japanese based vehicle manufacturers and will begin production with a fourth automaker in the near future. The EPB system functions as a conventional hydraulic brake for standard service brake applications, and as an electric brake for parking and emergency braking.
“Because EPB is electronically rather than mechanically controlled it can work with a variety of vehicle systems and sensors,” said Peter Lake, executive vice president, sales for TRW. “As an example, in the U.S. following NHTSA’s recent FMVSS 111 amendment that will require rear backup cameras, an EPB system could be integrated with the video signal and automatically brake the vehicle if a potential issue is detected.”
“In addition EPB can be integrated with a vehicle’s Electronic Stability Control system to enable full four-wheel anti-lock functionality enhancing safety in an emergency braking situation. There is also a drive away assist function which holds the vehicle in a stopped position without the need to constantly depress the brake pedal – an excellent traffic jam feature,” Lake said.
The EPB system, utilizing electrical cables and a control switch instead of a typical foot pedal or hand lever, simplifies routing and allows for greater freedom of design for vehicle interiors. Its smaller package becomes even more attractive as vehicle manufacturers continue to requisition vehicle space for new features and options and it can significantly reduce weight when compared to conventional park brake systems.
TRW continues to be a global leader in Electric Park Brake technology with more than 25 million units on world roadways. The Company was first-to-market with an integrated electronically controlled park brake, pioneering the technology in 2001.
