A vehicle warm-up control apparatus which can utilize waste heat of a converter no matter whether in a driving or parking process. The device includes: a boost converter (3) comprising a first switching device (T31) as an upper arm, a second switching device (T32) as a lower arm, and a reactor (L), wherein the second switching device (T32) is composed of a semiconductor device variable in resistance value, and when warm-up is requested, a control unit (6) executes warm-up control to set the resistance value of the second switching device higher than the resistance value during operation when the warm-up is not requested, and supply heat generated in the second switching device (T32) by passing current through the second switching device (T32) to a device for which the warm-up is requested.
本发明提供一种车辆的预热控制装置,其无论是行驶中还是停车中都利用转换器的废热进行预热。车辆的预热控制装置具备升压转换器(3),升压转换器(3)具有作为上支路的第一开关元件(T31)、作为下支路的第二开关元件(T32)、以及电抗器(L),其中,第二开关元件(T32)由电阻值可变的半导体元件构成,控制部(6)在存在预热要求的情况下,执行预热控制,所述预热控制将第二开关元件(T32)的电阻值设定为比不存在预热要求的情况的动作时的电阻值高,并使电流向第二开关元件(T32)流动而将由该第二开关元件(T32)产生的热向存在预热要求的设备供给。
