Abstract
A vehicle drive control device performs acceleration/deceleration running by alternately repeating acceleration running and deceleration running, wherein it compares between an efficiency of the motor at a first operation point determined by a rotation speed and a torque of a motor and an efficiency of the motor at a second operation point for outputting a higher torque than the first operation point, and if a difference between the efficiencies is greater than a determination value, the acceleration running at the second operation point and the deceleration running being repeated, the second operation point being set a maximum efficiency line of the motor with the rotation speed and the torque of the motor as parameters to perform the acceleration running, and if acceleration during the acceleration running becomes larger than an acceleration limit value, a rotating machine acting at least as an electric generator generating electricity to charge a battery.
