PROBLEM TO BE SOLVED: To avoid a state where power cannot be generated by a motor at the breakdown of a high-pressure battery and power cannot be supplied to a low-pressure battery, in a hybrid vehicle with a twin clutch-type transmission.SOLUTION: When the breakdown of a high-pressure battery (30) is detected, a driving force of an engine (2) is transmitted to an output shaft (CS) through a second transmission mechanism (G2) by engaging a second clutch (C2) to travel a vehicle, and a part of the driving force of the engine (2) is transmitted to a motor (3) through a fist clutch (C1) by setting a first transmission mechanism (G1) neutral and engaging the first clutch (C1) to generate power by the motor (3). Power supply to a 12 V battery (22) is covered only by the power generated by the motor (3). It is controlled so that the transmission and reception of the power of the high-pressure battery (30) are not performed, and upshift by the second transmission mechanism (G2) is prohibited and only downshift is permitted. |
