The integrated electric park brake (EPBi) system from TRW is a further development of its electric park brake technology (EPB). The EPBi removes the requirement for a separate electronic control unit (ECU) due to its integration with the electronic stability control system. According to the company, the EPBi system helps to enhance driving safety and comfort and provides greater freedom in interior design and packaging. A fully integrated part of the braking system, EPBi makes four-wheel anti-lock braking functionality possible during emergency braking. EPBi includes additional functions such as drive-away assist, automatic hill hold, and electronically controlled deceleration, which are features not available with conventional mechanical park brake systems. According to the company, the benefits of EPBi compared to EPB are the reduction of system complexity, mass, and installation effort in addition to offering vehicle manufacturers a potential cost reduction as a result of the elimination of the ECU.
