Abstract: A method for controlling a hybrid vehicle is provided. The method includes setting a driving path of the vehicle based on an input destination and current position and predicting a future speed of the vehicle using information regarding the driving path, environmental information, and driving pattern information of a driver. An optimum power distribution map is derived including an optimum SOC trajectory and a power distribution ratio of the engine and the motor using the predicted future speed. Additionally, engine power and motor power is distributed using the optimum SOC trajectory and a power distribution ratio of the engine and the motor.

Abstract: A refrigerator includes a housing and a door hinged to the housing. The hinge carries a door opening/closing apparatus in the form of a follower slide member carried by the door and arranged to slide upwardly along a camming slide member during opening of the door, and to slide downwardly along the camming slide member during closing of the door to assist in such closing. The follower slide member is able to rotate slightly before making contact with the camming slide member upon initial opening movement of the door so that the opening/closing apparatus does not increase the force needed to initially open the door.
