Power distribution method and power distribution control apparatus for vehicle

摘要

A vehicle has a transmission apparatus (19) that changes the distribution of power transmitted from a power source (11) to a plurality of wheels (16, 17, 24, 25). The method for distributing power of the vehicle includes detecting the temperature (Tx) of a part located on a power transmission path between the power source (11) and a wheel (16, 17, 24, 25) to which power is transmitted from the power source (11) through the transmission apparatus (19), the heat of the part being increased as the power distribution ratio is increased; determining that the current state is a specific state in which the detected temperature (Tx) reaches a previously set first reference temperature; and controlling the transmission apparatus (19) to lower the power distribution ratio to the wheel (16, 17, 24, 25) from the transmission apparatus (19) when the current state is determined to the specified state.
