<P>PROBLEM TO BE SOLVED: To realize proper charge/discharge control according to a capacitor state such as temperature of a storage apparatus to assure the life of an electric double layer capacitor which constitutes the storage apparatus, related to a vehicle hybrid system comprising a clutch which connects/disconnects the output shaft of an engine from the input shaft of a transmission, a rotary electric machine which acts both as a motor and as a generator, a power transmission mechanism which connects the input/output shaft of the rotary electric machine to the input shaft of the transmission, and the electric double layer capacitor which constitutes the storage apparatus connected to the rotary electric machine. <P>SOLUTION: There are provided a means (S4. 03) which detects the capacitor state of the storage apparatus, means (S4. 04-S4. 07 and S4. 10) which decides an abnormality of the capacitor state based on a detection signal, means (S4. 11 and S4. 12) which sets a limit value according to the abnormality of the capacitor state, and means (S4. 13 and S4. 14) which control charging/ discharging with the storage apparatus by deciding a torque command value for the rotary electric machine by considering the set value. <P>COPYRIGHT: (C)2004,JPO |
