Patents by Inventor Byoung Soo Yoo

Byoung Soo Yoo has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10974710
    Abstract: An electric vacuum pump applied to a vacuum boosting brake system is provided. The pump has a water containing capacity that is greater than a backflow water capacity of an internal space defined in a pump housing which forms vacuum pressure. The pump includes a watertight chamber that is coupled to an exhaust port of a pump housing.
    Type: Grant

  • Publication number: 20170158176
    Abstract: An apparatus and method are provided for determining a vehicle braking. The apparatus includes a braking light switch that generates a switch on signal or a switch off signal, corresponding to a brake operation of a vehicle. A sensor senses a pressure that corresponds to the brake operation and generates a pressure value that corresponds to the sensed pressure. A controller determines an operation of a brake based on the switch on signal, the switch off signal, and the pressure value, that are transmitted and also determines the brake to be operated when the switch on signal is received, or the pressure value is greater than a predetermined threshold pressure.

  • Patent number: 9168902
    Abstract: A method and a system controls braking of a vehicle. The method includes: detecting a pedal stroke, booster negative pressure, and master cylinder hydraulic pressure; setting target master cylinder hydraulic pressure on the basis of the detected pedal stroke and the detected booster negative pressure in a case in which a magnitude of the detected booster negative pressure is smaller than a magnitude of predetermined reference booster negative pressure; and compensating for the master cylinder hydraulic pressure in a case in which the detected master cylinder hydraulic pressure is smaller than the predetermined target master cylinder hydraulic pressure.
