Patent number: 10180369Abstract: The present invention relates to a fault diagnosis apparatus for a brake of a train, an automatic train operation system operated due to degradation of braking performance using the same, and a fault diagnosis method for the brake of the train. In particular, the present invention is directed to determining that a fault has occurred in the brake when the difference between the current acceleration of the train and the required acceleration is greater than or equal to a reference value and safely moving the train to a stopping point through a powering operation or coasting operation such that emergency braking is not applied by an automatic train protection (ATP) system if the fault has occurred in the brake.

Patent number: 7499826Abstract: A method of estimating a mass of a vehicle. If a yaw rate is smaller than a reference value, a straight direction model algorithm is applied to obtain an estimated mass. If a measured speed and a measured steering angle are larger than reference values, a lateral direction model algorithm is applied to obtain another estimated mass. If a measured vertical acceleration is larger than a reference value, a vertical direction model algorithm is applied to obtain yet another estimated mass. If each of the estimated masses is in an allowable range, and is constant for a given time period, the masses are applied to a recursive least square method, thereby estimating the mass of the vehicle.Type: GrantFiled: September 17, 2007Date of Patent: March 3, 2009Assignee: Hyundai Motor CompanyInventors: Kun-Soo Huh, Jong-Chul Jung, Dae-Gun Hong, Sung-Hyun Lim
