A method of controlling driving of a CVT vehicle during cornering performed by a controller, may include determining whether it is necessary to perform an auxiliary control process to enhance a re-acceleration response after entering the corner, by determining a travelling state of the vehicle; setting a target gear ratio instead of a gear ratio obtained based on a shift pattern when the determining produces an affirmative result indicating that it is necessary to perform the auxiliary control process; and performing gear shifting of a CVT to follow the target gear ratio set in the setting ofthe gear ratio. 一种控制CVT车辆转弯期间的行驶的方法，由控制器执行并可包括以下步骤：通过确定车辆的行驶状态来确定是否有必要执行用以提高进入弯道后的再加速响应的辅助控制处理；当确定步骤产生表示有必要执行辅助控制处理的肯定结果时，取代基于换挡模式获得的传动比而设定目标传动比；以及执行CVT的换挡以跟随在设定传动比的步骤中设定的目标传动比。
