A pulse reduction control system of a high-pressure hose and a controlling method thereof are provided to reduce the pulsation effectively by installing a sub high-pressure hose connected via a solenoid valve. A pulse reduction control system of a high-pressure hose comprises a hollow part(10a) and a spiral tuner(20) placed at the hollow part. The high-pressure hose(10) is penetrated through a hose inlet connection pipe(30) and a hose outlet connection pipe(40), and includes a sub high-pressure hose(11) joined by a solenoid valve(50) between the hose inlet connection pipe and the hose outlet connection pipe. The high-pressure hose has a first pulse reduction property(Q1), and the sub high-pressure hose has a second pulse reduction property(Q2). At least portions of the transmission characteristics in frequency band in the second pulse property are different from the first pulse property. The high-pressure hose is connected to a hydraulic pump(P) generating the hydraulic pressure, and to a steering unit(such as a gear) adjusting a steering wheel by supplying the hydraulic pressure. The solenoid valve is coupled with an electronic control device(60) for controlling the steering force according to a pulse signal due to the hydraulic pressure.
