Abstract: A method for controlling a vehicle includes determining the number of driving legs according to an output current target value of a DC-DC converter; selecting one or more legs to be switched as many as the number of the driving legs from among a plurality of legs included in the DC-DC converter based on accumulated operation time for each of the plurality of legs; and controlling an output current value of the DC-DC converter to follow the output current target value by switching the selected one or more legs.

Abstract: A vehicle is provided that includes a DC converter having a first end connected to a fuel cell, a second end connected to a high-voltage battery, and at least one switching element connected between the first end and the second end, a fuel cell control unit which controls an activation state of a running command for start of the fuel cell based on an on-off state of vehicle start, and a converter controller which controls a running state of the DC converter according to an initial start sequence, a shutdown sequence, or a restart sequence for the fuel cell based on the activation state of the running command.

Abstract: A direct current to direct current (DC-DC) converter, a vehicle including the converter, and a controlling method thereof are proposed. The DC-DC converter is capable of efficiently detecting and responding to miscoupling of a connector. The DC-DC converter includes a first inlet corresponding to a first DC terminal, a transformation circuit connected to the first DC terminal and a second DC terminal while being located therebetween, and a converter controller, wherein when receiving a voltage command corresponding to the first DC terminal from an external controller, the converter controller is configured to determine whether or not a connector coupled to the first inlet is miscoupled thereto based on whether or not a voltage of the first DC terminal follows the voltage command.

Abstract: A DC-DC converter, a vehicle including the converter, and a controlling method thereof are provided. The DC-DC converter includes a first capacitor connected to a first DC terminal, a second capacitor connected to a second DC terminal, a plurality of converting circuits each including at least an inductor and a plurality of switching elements, and connected to each other in parallel between the first capacitor and the second capacitor, and a controller configured to control an ON/OFF state of the plurality of switching elements provided of each of the converting circuits. When external power connection with respect to each of the first DC terminal and the second DC terminal is disconnected, the controller is configured to control states of the plurality of switching elements to sequentially provide a plurality of different discharge paths between opposite terminals of the second capacitor via the plurality of converting circuits.

Abstract: A DC-DC converter may include a first capacitor connected to a first DC end, a second capacitor connected to a second DC end, a power conversion circuit connected between the first capacitor and the second capacitor and including at least one switching element, and a controller determining, when the second capacitor is charged as the battery is connected to the second DC end, whether the at least one switching element has failed based on a first voltage that is a voltage between opposite ends of the first capacitor and a second voltage that is a voltage between opposite ends of the second capacitor.

Abstract: A seat-interlocking leg rest control system includes: a first actuator configured to move a seat for a vehicle, the seat including a seat cushion and a seatback, in a forward-backward direction or an upward-downward direction of the vehicle; a second actuator configured to rotate a leg rest, rotatably coupled to the front end portion of the seat cushion, in the upward-downward direction; and a controller connected to the first actuator and the second actuator to control operation of the second actuator such that the rotation angle of the leg rest is limited based on the position of the seat.
