PROBLEM TO BE SOLVED: To achieve stable 4WD start off by a driving force start at a front wheel side and rear wheel side without delay and equalizing each driving force of the front wheel and the rear wheel when the vehicle begins to move, when a four-wheel drive hybrid vehicle departs from idle stop conditions. SOLUTION: During an idle stop, an excitation current is made to flow continuously to a second induction motor 10. When starting the vehicle from the idle state, firstly the supply of a torque current to the second induction motor 10 and the supply of the excitation current to a first induction motor 2 are started after the timing of the braking force having begun to decrease, and then further with the timing of the braking force having decreased, the first induction motor 2 is supplied with the torque current, and an engine 1 is cranked to restart the engine 1. The driving force of the second induction motor 10 is decreased according to the rise of the total driving force of the engine 1 and the first induction motor 2, thus the start off is performed so that each driving force of the front and rear wheels when the vehicle begins to move is equal to each other. |
