Abstract

In a drive controller for a vehicle including: a drive source configured to output a drive force to a first axle serving as one of front and rear wheel axles; an electric motor configured to output a drive force to a second axle serving as the other of the front and rear wheel axles; a one-way power transmission device disposed on a power transmission pathway between the second axle and the electric motor so as to transmit a power drive force from the electric motor to the second axle; a two-way power transmission device that transmits a rotation power from the second axle to the electric motor or transmits the power drive force and a regeneration drive force from the electric motor to the second axle, the drive controller includes: a first detector that detects a speed of the vehicle or a rotation speed of the second axle; a target rotation speed determination section that determines a target rotation speed of the electric motor based on the speed of the vehicle or the rotation speed of the second axle; a second detector that detects a rotation speed of the electric motor; and a controller that controls the electric motor such that the rotation speed of the electric motor is synchronized with the target rotation speed and that controls an output torque of the electric motor or an activation of the two-way power transmission device, when the electric motor starts power drive or regeneration drive while the vehicle is traveling by the drive force from the drive source.
