<P>PROBLEM TO BE SOLVED: To provide a drive control device for a vehicle capable of reducing any impact due to backlash even when the rotational direction of the gear of a reduction gear on a power transmission path is changed. <P>SOLUTION: The drive control device for a vehicle is provided with: a drive source capable of outputting drive power to a first axle which is one of the front and rear wheel axles; an electric motor capable of outputting a drive power to a second axle which is the other axle; a reduction gear installed on a power transmission path between a second axle and the electric motor; a unidirectional power transmitting unit for transmitting the vehicle drive power from the electric motor to the second axle; and a brake for transmitting a rotational power from the second axle to the electric motor when the regenerative drive of the electric motor is performed. The drive control device for a vehicle is also provided with: a vehicle speed detection means; a means for determining the target rotational speed of the electric motor on the basis of the speed of the vehicle; a means for detecting the rotational speed of the electric motor; and a control unit which, when starting the drive of the electric motor in the traveling state of the vehicle from the drive source, controls the electric motor so that the rotational speed of the electric motor is synchronized with the target rotational speed, and controls the output torque of the electric motor or the drive of the brake. <P>COPYRIGHT: (C)2011,JPO&INPIT |
