<P>PROBLEM TO BE SOLVED: To provide a torque distribution control device of a vehicle capable of securing straight travel stability and turning travel stability in an abnormal time of a motor or a braking system where the wheel speed of the right and left wheels deviates from the target wheel speed. <P>SOLUTION: The vehicle is equipped with the right and left torque distribution control means where at least one set of right and left wheels of the front and rear wheels are driven by two motors respectively, and the torque distribution to the right and left wheels is controlled by a torque output command to both motors. The vehicle is provided with an abnormality determination means (step S2) which determines the abnormality when the difference between the actual wheel speed of the right and left wheels and the target wheel speed is not less than the rated value. When determining the abnormality by the abnormality determination means, the right and left torque distribution control means executes a torque distribution control (step S5 to step S15) responding to the abnormal time which adjusts the torque distribution to the right and left wheels so as to return the actual wheel speed of the right and left wheels to an appropriate value. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
