Abstract
The invention provides a warm-up control device of a hybrid electric vehicle, which warms up an engine for generator while extending the life of the engine and improves the quietness. If an engine temperature is not greater than a set temperature after the start of the engine for generator, the warm-up control device controls a load of the generator and controls an engine output in accordance with the load of the generator so as to maintain an engine revolution speed at a predetermined low revolution speed.
