The invention relates to a noise and vibration reduction device for a steering system, a car including the device and a noise and vibration reduction method for the system. The device is arranged on a hydraulic steering system. The device comprises a vibration sensor, a control unit and a steering oil tube valve. The vibration sensor is arranged on a steering high-pressure oil tube of the hydraulic steering system to detection the vibration situation of the steering high-pressure oil tube. The control unit is electrically connected with the vibration sensor which sends detected vibration signals to the control unit. A steering oil tube valve is arranged on the steering high-pressure oil tube and is electrically connected with the control unit which controls the steering oil tube valve to change the oil passing section size according to the vibration signals, and accordingly, the steering liquid flowing speed is changed, and the liquid flow frequency is changed.
