<p><P>PROBLEM TO BE SOLVED: To provide a deterioration determining device capable of correctly determining the deterioration of a battery even in a winter when the battery is in a low-temperature. <P>SOLUTION: In starting of an engine 9, a hybrid control section 15 sets a motor generator 7 and a clutch 33 in a non-connected drive state, an internal-resistance detection section 57 detects internal resistance of a battery 9, a battery temperature sensor 55 detects an environmental temperature, and the hybrid control section 15 determines the degree of deterioration of the battery 9 based on the internal resistance detected by the internal-resistance detection section 57 and on the environmental temperature detected by the battery temperature sensor 55. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
