Control device for hybrid four-wheel-drive vehicle and hybrid four-wheel-drive vehicle
First Claim
1. A control device for controlling a hybrid-four-wheel-driven vehicle wherein one of the front-wheel pair and the rear-wheel pair is engine-driven-wheel pair which is driven by an engine, and the other pair is an electric-motor-driven-wheel pair which is driven by an electric motor, comprising:
- slipping detecting means for detecting slipping of said engine-driven wheels;
first output control means for reducing the output of the engine and reducing the output of the electric motor corresponding to the reduction of engine output when the slipping detecting means detect slipping;
second output control means for increasing the output of the electric motor and increasing the output of the engine corresponding to the increase of electric-motor output when the slipping detecting means detect slipping; and
switching means for making switching between said first output control means and said second output control means.

Abstract
A control device controls a hybrid-four-wheel-driven vehicle wherein one of the front-wheel pair and the rear-wheel pair is an engine-driven-wheel pair which is driven by an engine, and the other pair is an electric-motor-driven-wheel pair which is driven by an electric motor. In the event of slipping of the engine-driven wheels, the system increases the engine output so as to increase the driving force of the electric-motor-driven wheels for increasing the total driving force mad up of the engine-driven-wheel driving force and the electric-motor-driven-wheel driving force, thereby improving acceleration performance, unlike conventional techniques. This provides a control device for suppressing deterioration in acceleration performance of the vehicle in a case of slipping of engine-driven wheels during acceleration.
