<P>PROBLEM TO BE SOLVED: To provide a control device of a hybrid electric vehicle, which is advantageous to the suppression of the deterioration of a battery caused by an excessive rise of a battery temperature while suppressing fuel consumption. <P>SOLUTION: A temperature rise rate operation means 48B calculates a temperature rise rate α which is a rise amount per unit time of the battery temperature TB on the basis of the battery temperature TB which is detected by a battery temperature sensor 46. An engine control means 48C starts a generator by starting an engine 22 when the temperature rise rate α calculated by the temperature rise rate operation means 48B is not lower than an engine start determination value α1 which is a preset threshold. An engine start determination value setting means 48D sets the engine start determination value α1 so that the engine start determination value α1 is lowered as the battery temperature TB detected by the battery temperature sensor 46 becomes high. <P>COPYRIGHT: (C)2013,JPO&INPIT |
