Abstract: A drive control apparatus includes a motor control unit and a gear shift control unit, and controls a power transmission system including first and second motors and a gear shift mechanism. When the gear shift mechanism is changed from a first gear stage to a second gear stage during deceleration of the vehicle, the motor control unit controls the first motor to be at a target rotation speed determined based on a gear ratio of a second power transmission gear and a rotation speed of an output shaft, and controls a second motor such that required brake torque is generated by the second motor. The gear shift control unit controls the gear shift mechanism so as to be in a neutral state in which power is not transmitted between an input shaft and the output shaft, until a rotation speed of the first motor becomes the target rotation speed.

Abstract: A second rotor and a third rotor are accommodated in a first rotor. A fitting portion of the third rotor is located in an engagement hole of the second rotor to engage the third rotor with the second rotor. The third rotor is rotational about an axis, which is eccentric to an axis of the first rotor, to vary a relative rotational phase of the first rotor to the second rotor and to accelerate and decelerate rotation of the second rotor. When friction arises between the second rotor and the fitting portion, a frictional force acts in a direction to reduce a rotational moment acting on the third rotor. A friction coefficient between the second rotor and the fitting portion is greater than a friction coefficient between ferrous objects.
