TRW Unveils EPB System
The company is planning to launch front EPB in 2013.
TRW's EPB offers a number of safety benefits in addition to space optimization in the vehicle's passenger compartment thanks to the elimination of the handbrake lever or pedal.
Similar to conventional rear EPB applications, the front axle system offers simple vehicle assembly within the wheel environment and enhances emergency braking performance through integration with ABS/ESC in the event of hydraulic failure, said TRW.
In addition, a wide range of comfort and safety features can be included, for example: hill and drive away assist, electronically controlled deceleration (ECD), rollaway detection, and premium stand still management to support stop and go and auto hold functionality.
Josef Pickenhahn, vice president of braking engineering at TRW, said: â€œUntil recently, vehicle manufacturers have been reluctant to routinely fit disc brakes to the rear axles of small cars - normally a pre-requisite for EPB because they are relatively expensive and lower cost drum brakes can comfortably meet performance specifications.
â€œOur front axle EPB has the potential to further reduce the cost and weight of the rear drum brake systems which no longer require shoe actuators, linkages, fixing devices, cables, or the handbrake lever itself. It's a further example of how we're taking existing products and improving their affordability and fuel savings potential in line with market requirements to deliver the safety and efficiency that all drivers deserve.â€
Will the new system benefit vehicle manufacturers?
