Abstract:
1. A drive power transmission device comprising: a differential control device configured to distribute transmission torque from an engine to front and rear wheels, the differential control device further configured to vary a torque distribution ratio between the front and rear wheels; and a control device configured to execute a tight-corner braking prevention control under which the transmission torque of the differential control device to the front wheels or the rear wheels is decreased to prevent a tight-corner braking phenomenon from occurring when a turning radius of a predetermined one wheel of the wheels or a motor vehicle is equal to or smaller than a predetermined turning radius, wherein the control device is further configured so that when the motor vehicle under the tight-corner braking prevention control being executed is restarted after being stopped momentarily or is accelerated to a higher speed than a predetermined vehicle speed from a lower speed than the predetermined vehicle speed, the control device executes the tight-corner braking prevention control from beginning of the restarting or the acceleration.
