TRW's Hydraulic Park Brake (HPB) system combines TRW's EPB and ESC technology to provide enhanced park brake functionality. By utilizing electronic communication and hydraulic pressure assistance from TRW's ESC system at the onset of a park brake apply, EPB functionality is achieved at a competitve cost. Additional benefits include lighter weight, quicker release times, and reduced complexity when compared to existing systems. Suitable for both cars and light trucks, TRW's HPB approach is another example of integrating different safety systems to provide greater value and performance. Features •Electro-hydraulic pressure generated by TRW's ESC system allows for HPB caliper actuator optimization •Vehicle stabilization by ESC in case of emergency HPB activation while driving •Reduced power consumption of HPB caliper actuator results in lower system noise •No pressure re-apply required for release – improves release time over existing systems •Integration of automatic hold, hill assist/drive-away and other functions typically provided by TRW‘s EPB systems •Increased clamp force possible if required for light trucks •Elimination of discreet ECU provides greater value, lighter weight, and reduced complexity
