The invention provides a travel control method and a travel control device for a vehicle. The present invention makes it possible to accurately predict the elastic slip limit of a tire of a main drivewheel, prevent a sharp decrease in power transmission efficiency and instability in performance during straight travel, and improve the followability of an actual travel path with respect to a targettravel path during turning. A vehicle is provided with a main drive wheel and a sub drive wheel to which power from a drive source is transmitted. A driving state of only transmitting power to the main driving wheel and a driving state of transmitting power to the main driving wheel and the auxiliary driving wheel can be realized; the vehicle travel control method performs the following control:a control for controlling the travel of a vehicle; before tires of main drive wheels of a traveling vehicle exceed an elastic slip limit, a drive state in which power is transmitted only to the main drive wheels is set, and when tires of the main drive wheels of the traveling vehicle exceed the elastic slip limit, a drive state in which power is transmitted to the main drive wheels and sub drive wheels is set.

    本发明提供车辆的行驶控制方法和行驶控制装置。可准确地预测主驱动轮的轮胎的弹性滑动极限,防止直行时的动力传递效率的急剧降低及性能的不稳定化,且使转弯时的实际行驶轨道相对于目标行驶轨道的追随性提高。车辆具备被传递来自驱动源的动力的主驱动轮和副驱动轮,能够实现仅向主驱动轮传递动力的驱动状态及向主驱动轮和副驱动轮传递动力的驱动状态,该车辆的行驶控制方法进行如下的控制:在行驶中的车辆的主驱动轮的轮胎超过弹性滑动极限之前,设为仅向主驱动轮传递动力的驱动状态,当行驶中的车辆的主驱动轮的轮胎超过弹性滑动极限时,设为向主驱动轮和副驱动轮传递动力的驱动状态。
