An apparatus for controlling optimization of a charging amount of a battery for a vehicle charged with external power includes: a map storage, a position detector, and a controller to control the map storage and the position detector. The controller acquires a current position of the vehicle when a driver's desired charging setting value is input, acquires altitude information of topography corresponding to a driving path, calculates a gain charging amount in an uphill or downhill section on the driving path based on the altitude information, calculates an optimum charging setting value based on the driver's desired charging setting value and the gain charging amount, calculates a final target charging amount based on the optimum charging setting value and a current residual charging amount, and performs optimum charging of the battery.

A vehicular coolant flow system includes: a main cooling circuit configured to circulate a coolant through a power electronic device mounted on a vehicle so as to cool the power electronic device; a heat-radiating device provided in the main cooling circuit so as to cool the coolant; a bypass circuit that branches off at a point between the power electronic device of the main cooling circuit and the heat-radiating device, bypasses the heat-radiating device, and merges with the main cooling circuit; a heating device connected to the bypass circuit and heated by the coolant that has cooled the power electronic device; a first adjustment valve positioned at a point at which the bypass circuit branches off from the main cooling circuit or merges with the main cooling circuit; and a controller that controls the first adjustment valve so as to adjust a flow rate of the coolant supplied to the bypass circuit.

A control method and apparatus of a hybrid vehicle are provided. The control method includes determining whether the speed of a motor exceeds a first threshold value, when supply of power to a battery is cut off and thus the hybrid vehicle is driven by an engine. The speed is then adjusted to be the first threshold value or less, when the speed exceeds the first threshold value.

Control method and apparatus of hybrid electric vehicle

A method and system for controlling a low-voltage DC/DC converter (LDC) of a hybrid electric vehicle (HEV) includes performing a trial starting comprising steps of: trying ignition start, performing an immobilizer authentication process, and turning on a main relay of a high-voltage battery. The LDC is controlled after the trial starting, so that an operating voltage is applied from the LDC to an electric load including various kinds of controllers, thereby allowing starting of the HEV.
