Method and apparatus for applying a brake force in a towed vehicle hydraulic brake system proportional to a hydraulic pressure generator power input

摘要

A braking system for a towed vehicle having a hydraulic brake system wherein a continuously variable hydraulic pressure is generated to provide a corresponding and proportional brake force in the towed vehicle. A hydraulic pressure generator having an electric motor with variable electric input is employed to provide a corresponding a proportional hydraulic pressure by a hydraulic pressure generator, wherein the resulting variable hydraulic pressure is employed to provide a proportional braking force in the towed vehicle.
