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.
