Abstract

When there is a demand for a heating operation of a vehicle and when there is a remaining charging capacity in a main battery, an upper limit value of a charging state of the battery is changed to a level-up upper-limit value, which higher than an ordinary upper-limit value. And an operating mode of an engine is changed to an efficiency prioritizing mode. When there is no remaining charging capacity in the main battery, the upper limit value of the charging state is changed to the ordinary upper-limit value. And the operating mode of the engine is changed to a waste-heat prioritizing mode, an engine efficiency of which is lower than that of the efficiency prioritizing mode. According to such a control, it becomes possible to warm up the engine and the battery, even in the case that there is no remaining charging capacity because of high charging state in the battery.
