PROBLEM TO BE SOLVED: To improve the efficiency of regeneration of a motor by providing a means for computing the target output in response to the speed reduction condition of a vehicle, a means for computing the optimal number of revolution, which can obtain the maximum regenerative output of the motor, in response to the computed target output, and a means for controlling the number of revolution of the motor at the optimal number of the revolution. SOLUTION: Various operation parameter is detected (S121), and the basic change gear ratio RBASE is computed (S122). Continuously, target change gear ratio RK is computed on the basis of the computed deviation of the number of revolution SNE (S123), and the computed shift actuator operated variable is set in an output register (S125). At the time of regenerating the reduction, the optimal number of revolution NEOPT, which can obtain the maximum regenerative output of the motor, is computed, and change gear ratio is controlled so that the number of revolution of the motor achieves the optimal number of revolution NEOPT. Kinetic energy of a vehicle at the time of speed reduction can be thereby efficiently recovered as the electric energy. |
