In this study, the traction/braking force distribution in electric vehicles for minimizing travel resistance when taking a turn is investigated in relation with power conservation. The travel resistance of a front-steer-rear-drive vehicle decreases owing to the faster rotation of the outer drive wheel than that of the inner one. The yaw moment is generated by the difference between the rotation speeds of the left and right wheels; hence, the power consumption rate is minimized by weaker yaw moment compared to that minimizes the travel resistance. Owing to this relation, the power conservation effect is not so large as expected by the decrease of the travel resistance. In the case of a four-wheel-drive vehicle, the equivalent distribution of the traction/braking force between the front and rear wheels enhances the power conservation effect but only to a limited extent.
