1. A four-wheel-drive vehicle comprising:
a drive power source configured to include at least a rotary machine;
a drive power distribution device configured to transmit a drive power from the drive power source to main driving wheels and sub driving wheels and to adjust a main-side distribution ratio which is a ratio of a drive power which is transmitted to the main driving wheels to a total drive power which is transmitted from the drive power source to the main driving wheels and the sub driving wheels; and
a control device configured to control the rotary machine and the drive power distribution device,
wherein the control device is configured to perform regeneration control using the rotary machine at the time of deceleration of the vehicle, to limit a regenerative torque of the rotary machine using a preset upper limit of the regenerative torque in the regeneration control, and to set the upper limit to a value which is larger when the main-side distribution ratio is small than when the main-side distribution ratio is large.
