Overview


The Hydraulic Power Brake (HPB) is a braking and vehicle control system for vehicles in class 4 through 7 and buses that are equipped with hydraulic brakes. The full power system does not require an external source to provide power assist to achieve a low pedal effort as required in a conventional hydraulic braking system. HPB provides “Best in Class” stopping distance and pedal feel. HPB also provides brake control functions including ABS, automatic traction control (ATC), electronic brake force distribution (EBD), and optional auto-apply electronic parking brake control.
HPB also has the advantage of serving as an enabling platform, allowing for custom tailoring to meet the needs of various OEMs and fleet applications. In addition to ATC, the system can accommodate additional optional features such as electronic stability control, hill holder, and 4-wheel traction control.
