Four-wheel drive vehicle

A four-wheel drive vehicle comprising:

• main drive wheels and auxiliary drive wheels;
• a drive-power distribution device including (a) a drive-power distribution clutch configured to distribute a drive power of a drive power source, between the main drive wheels and the auxiliary drive wheels, (b) an electric motor, (c) a press mechanism configured to press the drive-power distribution clutch by converting a rotary motion of the electric motor into a linear motion in an axial direction of the drive-power distribution clutch, the drive-power distribution device being configured to adjust a torque capacity of the drive-power distribution clutch so as to adjust a drive-power distribution ratio that is a ratio of distribution of the drive power between the main drive wheels and the auxiliary drive wheels;
• an engine serving as the drive power source and configured to output the drive power;
• and
• a control apparatus configured to execute a drive-power distribution control for adjusting the drive-power distribution ratio, and configured to execute an engine automatic-stop control for causing the engine to be automatically stopped upon satisfaction of an engine-stop condition,
• wherein the control apparatus is configured, when the engine is in a stop state by execution of the engine automatic-stop control, to inhibit change of the drive-power distribution ratio which is to be made by change of a rotational direction of the electric motor.
