Abstract: An electrified vehicle includes: a battery; a motor drive device configured to drive a motor through an inverter, based on a voltage of the battery; and a battery controller configured to determine whether to perform output limiting on the battery, based on whether a ratio of regenerative braking is less than or equal to a preset ratio, wherein the ratio of regenerative braking is varied according to an amount of charging of the battery and an amount of discharging of the battery within a preset time interval, and adjust, based on the output limiting being performed on the battery, a derate ratio associated with a battery output limit value.

Abstract: Disclosed herein are a cooperative driving method based on driving negotiation and an apparatus for the same. The cooperative driving method is performed by a cooperative driving apparatus for cooperative driving based on driving negotiation, and includes determining whether cooperative driving is possible in consideration of a driving mission of a requesting vehicle that requests cooperative driving with neighboring vehicles, when it is determined that cooperative driving is possible, setting a responding vehicle from which cooperative driving is to be requested among the neighboring vehicles, performing driving negotiation between the requesting vehicle and the responding vehicle based on a driving negotiation protocol, and when the driving negotiation is completed, performing cooperative driving by providing driving guidance information for vehicle control to at least one of the requesting vehicle and the responding vehicle.

Abstract: The present invention relates to a sword for a trainee in the art of swordsmanship; and more particularly, to a multistructured sword of a double or triple structure having a shock-absorbing space in a sword body. Accordingly, the trainee can effectively practices stabbing and cutting actions in the traditional swordsmanship by reducing a shock imposed on him. The present invention includes: a grip formed at an end of the training sword; a sword body member, wherein the sword body member includes at least one sword body inner cover for reducing a shock generated by a striking action and a sword body outer cover, which covers the sword body inner cover, wherein a gap is provided between the sword body inner cover and the sword body outer cover; a cross-guard formed at a boundary between the sword body member and the grip; and a scabbard for protecting the sword body member, wherein a length of the scabbard is shorter than that of the sword body member so that the sword body member passes through the scabbard.
