应用程序生成用户界面，该用户界面包括采用虚拟车辆的第一视角或第三视角对虚拟世界进行观察的行驶画面、以及叠加在该用户界面上的目标交互控件。目标交互控件是用于触发虚拟车辆处于漂移状态的控件或控件组。
步骤S102，根据操作开始事件控制虚拟车辆在虚拟世界中处于漂移状态；
在一些实施例中，操作开始事件是用户操作在目标交互控件上开始作用时触发的。可选地，目标交互控件包括触摸显示屏上显示的方向控件和漂移控件。或者，目标交互控件是赛车驾驶模拟外设上的若干个物理组件所对应的控件。
在一些实施例中，操作开始事件是通过触摸显示屏上的触控操作所触发的；或者，也可以是通过控制外部输入设备的物理操作所触发的，比如：控制鼠标、或VR手柄等物理操作所触发的。
在一些实施例中，用户操作包括单击操作、连击操作、长按操作、或滑动操作等类型，本实施例不对触控操作的类型进行限定。
比如，操作开始事件是用户同时按压左方向键和漂移控件的触控操作在开始触摸时所产生的；或者，操作开始事件是用户同时按压右方向键和漂移控件的触控操作在开始触摸时所产生的。
漂移状态是指车头方向与行驶方向之间产生较大的夹角，使车身侧滑过弯的移动状态。车头方向是指向车头正前方的方向。行驶方向是虚拟车辆在 行驶过程中的速度所对应的方向，或者说，行驶方向是虚拟车辆在地面环境上的实际移动方向。
步骤S103，在接收到目标交互控件对应的操作结束事件后，若车头方向与行驶方向之间的夹角大于或等于第一阈值时，则控制虚拟车辆保持漂移状态。
在一些实施例中，终端需要监测虚拟车辆的车头方向与行驶方向之间的夹角。示意性地，包括但不限于如下四种方式中的至少一种：
1、在虚拟车辆处于漂移状态的过程中，实时监测虚拟车辆的车头方向与行驶方向之间的夹角；
2、当接收到目标交互控件对应的操作结束事件后，终端实时监测虚拟车辆的车头方向与行驶方向之间的夹角；操作结束事件是用户操作在目标交互控件上开始消失时触发的；比如，操作结束事件是同时按压方向键和漂移控件的触控操作在取消触控时所产生的事件。
3、终端每隔预定时间间隔监测虚拟车辆的车头方向与行驶方向之间的夹角；
4、终端在接收到方向控制操作时，监测虚拟车辆的车头方向与行驶方向之间的夹角。
在接收到目标交互控件对应的操作结束事件后，若终端车头方向与行驶方向之间的夹角大于或等于第一阈值时，则控制虚拟车辆保持漂移状态。“保持漂移状态”是指：在虚拟车辆处于漂移状态的过程中，即便用户不再施加漂移触发操作，但只要车头方向与行驶方向之间的夹角保持大于或等于第一阈值，则终端也自动控制虚拟车辆处于漂移状态(或者说，延续漂移状态不中断)。
如图2所示，终端显示赛车程序的用户界面20，该用户界面20包括：左方向键21、右方向键22、漂移按键23和虚拟车辆24，左方向键21是用来控制虚拟车辆24向左侧移动的控件，右方向键22是用来控制虚拟车辆24向右侧移动的控件，漂移按键23是用于触发虚拟车辆24处于漂移状态的控件。
当虚拟车辆24在弯道中行驶时，用户同时按压右方向键22和漂移按键23作为漂移触发操作(图中以黑色填充色代表控件被按下)，终端接收到该 漂移触发操作后，控制虚拟车辆24处于漂移状态。
当用户取消同时按压右方向键22和漂移按键23(图中以白色填充色代表控件未被按下)后，终端监测到该漂移触发操作结束，然后终端监测虚拟车辆24的车头方向和行驶方向之间的夹角α大于或等于阈值，则终端控制虚拟车辆24保持漂移状态。
综上所述，本实施例提供的方法，在接收到目标交互控件对应的操作结束事件时，若车头方向与行驶方向之间的夹角大于或等于第一阈值，则控制虚拟车辆保持漂移状态；使得在控制保持虚拟车辆处于漂移状态的过程中，用户可以只控制车头方向与行驶方向之间的夹角即可，不需要同时按压方向键和漂移控件，只需要按压方向键来控制车头方向即可，降低了操作难度，提高了在某些不适合双手长时间操作场景下的人机交互便捷度。
请参考图3，其示出了本申请另一个示意性实施例提供的虚拟世界中的虚拟车辆漂移方法的流程图。本实施例以该方法应用于运行有应用程序的终端中来举例说明，该应用程序是支持虚拟车辆在行驶过程中处于漂移状态的程序，该应用程序用于执行如下方法。该方法包括：
步骤S301，启动应用程序。
终端上安装有各种各样的应用程序。终端的桌面上可以显示有应用程序的启动图标。
用户可以点击应用程序的启动图标，终端在该启动图标被触发后，启动该应用程序。该应用程序是提供有虚拟环境以及位于虚拟环境中的虚拟车辆的应用程序。该应用程序还支持虚拟车辆在行驶过程中处于漂移状态。
步骤S302，显示应用程序的用户界面，该用户界面包括虚拟车辆在虚拟世界中行驶的行驶画面。
终端运行该应用程序，显示该应用程序的用户界面。该用户界面包括虚拟车辆在虚拟世界中行驶的行驶画面。该行驶画面上显示有按照虚拟车辆的第一视角或第三视角对虚拟环境进行观察的画面。第一视角也称为驾驶员视角或车内视角，第三视角也称为车后视角或远视角。
当虚拟世界是三维虚拟世界时，第一视角可以由设置在驾驶员位置的第一摄像机实现；第三视角可以由设置在虚拟车辆后面的第二摄像机来实现。 该第一视角和第三视角会跟随虚拟车辆的移动而移动。本实施例中，以第三视角来对行驶画面进行举例说明，但对此不加以限定。
在一些实施例中，该用户界面上还在行驶画面上叠加有各种类型的控件。该控件至少包括：方向键和漂移控件，方向键是用于控制虚拟车辆的移动方向的控件，方向键包括前方向键、左方向键、后方向键和右方向键中的至少一种。漂移控件是用于控制虚拟车辆触发和/或保持漂移状态的控件，当方向键和漂移控件被同时按下时，控制虚拟车辆进入漂移状态。当方向键和漂移控件被持续按压时，虚拟车辆在按压持续期间保持漂移状态。
本实施例中，以目标交互控件包括方向键和漂移控件来举例说明。
在一些实施例中，该控件还包括：排名显示控件、速度信息控件、缩略地图控件、刹车控件、喷气控件、和氮气加速控件中的至少一种。排名显示控件是用于显示当前虚拟车辆在所有虚拟车辆中的赛车排名的控件。速度信息控件是用于显示个人记录时间、单圈赛车时间、和本局总赛车时间中的至少一项时间信息的控件。缩略地图控件是以俯视视角采用预设缩放比例对整个赛道地图(以及当前虚拟车辆在赛道地图上所在的实时位置)进行显示的控件。刹车控件是控制虚拟车辆减速的控件。喷气控件是控制虚拟车辆在相对较短的第一时间段内进行爆发性加速的控件，第一时间段的时长可以是固定时长。氮气加速控件是控制虚拟车辆在相对较长的第二时间段内进行爆发性加速的控件，第二时间段的时长可以是根据氮气属性值的多少来动态确定的。
在一些实施例中，喷气控件和氮气加速控件均为奖励性道具控件，需要虚拟车辆在行驶过程中满足预设条件时，得到该奖励性道具后才能触发使用。否则，喷气控件和氮气加速控件会被显示为无法使用的非激活状态。示意性的，氮气加速控件是可用氮气值累积达到门限值后，才能触发使用的道具控件。
步骤S303，在虚拟世界中的虚拟车辆处于正常行驶状态的过程中，接收目标交互控件对应的操作开始事件。
用户控制虚拟车辆在虚拟世界中的地面环境上进行行驶。在行驶过程中，用户可以使用方向键来控制虚拟车辆的行驶方向。
如图4所示，当虚拟车辆在虚拟世界中行驶时，虚拟车辆会受到正常行 驶牵引力F1和阻力f的影响。正常行驶牵引力F1是指向车头前方的牵引力，阻力f包括来自地面的摩擦力和风阻中的至少一种。正常行驶牵引力F1等于或大于摩擦力f。
在处于正常行驶状态的行驶过程中，用户还可在目标交互控件上触发漂移触发操作。在一些实施例中，漂移触发操作包括作用于漂移控件上的触发操作。或者，漂移触发操作包括作用于方向控件和漂移控件上的触发操作。或者，漂移触发操作包括作用于驾驶模拟外设上的触发操作。
在一些实施例中，漂移触发操作可以是通过触摸显示屏触发的操作；或者，也可以是通过控制外部输入设备触发的操作，比如：控制鼠标、VR手柄、驾驶模拟外设等触发的操作。驾驶模拟外设包括方向盘、档位杆、油门和刹车中的至少一项。
在一些实施例中，漂移触发操作可以是单击操作、连击操作、长按操作、或滑动操作等类型，本实施例不对漂移触发操作的类型进行限定。
比如，漂移触发操作是同时按压左方向键和漂移控件的操作；或者，漂移触发操作是同时按压右方向键和漂移控件的操作。
以漂移触发操作是同时按压触摸屏上显示的方向键和漂移控件为例，当上述触摸屏检测到用户触控时，终端的操作系统中会产生触控开始事件。该触控开始事件也即操作开始事件。
示意性的，终端的操作系统中的触控事件(touch)会在用户手指放在屏幕的时候、在屏幕上滑动的时候或者是从屏幕上移开的时候触发。触控事件可以有如下几种：
touchstart事件(触控开始事件)：当手指开始触控屏时触发，即使在已经有一个手指放在触摸屏上的情况下，当有其它手指触控屏时，也会触发该事件。
touchmove事件(触控移动事件)：当手指在触摸屏上滑动的时候连续触发。在该事件发生期间，调用preventDefault()事件可以阻止滚动。
touchend事件(触控结束事件)：当手指从触摸屏上离开的时候触发。
终端中的应用程序可以将上述程序层面获得的触控开始事件，确定为目标交互控件对应的操作开始事件。
步骤S304，根据操作开始事件控制虚拟车辆在虚拟世界中处于漂移状态。
漂移状态是指让车头方向与行驶方向之间产生较大的夹角,使车身侧滑过弯的移动状态。车头方向是指向虚拟车辆的车头正前方，行驶方向是虚拟车辆在虚拟世界中移动时的方向。
步骤S305，监测虚拟车辆的车头方向与行驶方向之间的夹角。
在一些实施例中，终端监测虚拟车辆的车头方向与行驶方向之间的夹角，包括但不限于如下四种方式中的至少一种：
1、在虚拟车辆处于漂移状态的过程中，实时监测虚拟车辆的车头方向与行驶方向之间的夹角；
2、当接收到目标交互控件对应的操作结束事件后，终端实时监测虚拟车辆的车头方向与行驶方向之间的夹角；操作结束事件是用户操作在目标交互控件上开始消失时触发的；比如，操作结束事件是同时按压方向键和漂移控件的触控操作在取消触控时所产生的事件。
3、终端每隔预定时间间隔监测虚拟车辆的车头方向与行驶方向之间的夹角；
4、终端在接收到方向控制操作时，监测虚拟车辆的车头方向与行驶方向之间的夹角。
在本实施例中，当用户不再触摸目标交互控件(比如用户手指在方向键和漂移控件上松开)时，终端的操作系统会产生目标交互控件对应的touchend事件，终端中的应用程序将touchend事件确定为操作结束事件。当接收到目标交互控件对应的操作结束事件后，终端监测虚拟车辆的车头方向与行驶方向之间的夹角。
在一些实施例中，在监测夹角的过程中，终端接收用户的方向控制操作，根据方向控制操作改变虚拟车辆的车头方向，确定改变后的车头方向与行驶方向之间的夹角。方向控制操作可以是作用于方向键上的操作，也可以是作用于方向盘上的操作。
比如，方向控制操作是按压左方向键的操作；又比如，方向控制操作是按压右方向键的操作。
在终端确定虚拟车辆的车头方向与行驶方向之间的夹角后，终端还判断该夹角与第一阈值和第二阈值之间的大小关系，第一阈值大于第二阈值。示意性的，第一阈值为45度，第二阈值为10度。
当该夹角大于或等于第一阈值时，进入步骤S306；当该夹角小于第一阈值且大于或等于第二阈值时，进入步骤S307；当该夹角小于第二阈值时，进入步骤S311。
当漂移触发操作结束后，虚拟车辆的车头方向或行驶方向会受到牵引力方向、方向控制操作以及阻力等多方面因素的影响而改变。而且由于用户有可能多次施加方向控制操作，因此本步骤可以对应地执行多次。
步骤S306，在接收到目标交互控件对应的操作结束事件后，若车头方向与行驶方向之间的夹角大于或等于第一阈值时，沿车头方向向虚拟车辆增加动态拖漂牵引力，该动态拖漂牵引力用于控制虚拟车辆保持漂移状态。
当用户在目标交互控件上触发的漂移触发操作结束后，若终端确定虚拟车辆的车头方向与行驶方向之间的夹角大于第一阈值，则终端沿车头方向向该虚拟车辆增加动态拖漂牵引力，该动态拖漂牵引力用于控制虚拟车辆保持漂移状态。
在一些实施例中，该“保持漂移状态”可称为拖漂状态。
如图5所示，虚拟车辆的动态拖漂牵引力F2的方向指向车头的正前方，处于漂移状态的虚拟车辆按照速度V沿行驶方向进行移动，该虚拟车辆还收到与速度V反向的摩擦力f的影响，动态拖漂牵引力F2在行驶方向上的分量F21等于或大于摩擦力f，使得虚拟车辆保持在漂移状态。同时，动态拖漂牵引力F2的另外一个牵引力分量F22会改变车头方向，需要用户的方向控制操作来控制虚拟车辆的车头方向。可选地，在正常行驶状态下，摩擦力f与虚拟车辆的速度呈正相关关系。
在一些实施例中，应用程序还会增加一个额外的回正力，该回正力用于在无控制信号时，引导虚拟车辆在漂移过程中自动回正车头方向和行驶方向重合。
在一些实施例中，该动态拖漂牵引力在行驶方向上的牵引力分量等于或大于阻力。
在一些实施例中，该动态拖漂牵引力的大小与虚拟车辆的速度呈正相关关系。或者，在预设速度区间内，动态拖漂牵引力的大小与虚拟车辆的速度呈正相关关系；在超出该预设速度区间后，动态拖漂牵引力的大小保持不变。
在一个可能的实现方式中，虚拟车辆收到的阻力为地面摩擦力，该地面 摩擦力在预设速度区间内与虚拟车辆的速度呈正相关关系，且该地面摩擦力的方向与行驶方向相反，虚拟车辆所受到的动态拖漂牵引力在行驶方向上的牵引力分量与地面摩擦力保持相同，或者，该牵引力分量会略大于地面摩擦力。以使得虚拟车辆保持漂移状态。
步骤S307，在接收到目标交互控件对应的操作结束事件后，若车头方向与行驶方向之间的夹角大于第一阈值时，将虚拟车辆的地面摩擦力，从第一摩擦力数值修改为第二摩擦力数值；第一摩擦力数值大于第二摩擦力数值。
在一些实施例中，第一摩擦力数值是根据虚拟车辆的速度实时确定的。在预设速度区间内，虚拟车辆的速度和地面摩擦力呈正相关关系。
在一些实施例中，第二摩擦力数值是预先设定的较小经验值。当应用程序在保持漂移状态中减小虚拟车辆的地面摩擦力时，可以降低地面摩擦力对虚拟车辆的速度的衰减，从而使得虚拟车辆更加容易地保持在漂移状态。
当虚拟世界中存在多个虚拟车辆时，每个虚拟车辆的地面摩擦力可以互相独立设置，视虚拟车辆的当前速度以及行驶状态而定。
步骤S308，在漂移状态的持续期间，持续增加虚拟车辆的氮气属性值。
在虚拟车辆处于漂移状态的过程中，应用程序根据漂移状态的持续期间，持续增加氮气加速控件的氮气属性值。该持续时间与累积的氮气属性值呈正相关关系。
步骤S309，当氮气属性值达到触发门限值时，将虚拟车辆的氮气加速控件激活为可用状态。
氮气加速控件对应有自身的触发门限值。当氮气属性值未累积到触发门限值时，氮气加速控件处于不可用状态，未激活状态是在用户界面上显示但不可触发的状态，或者，未激活状态是在用户界面上不显示的状态。当氮气属性值累积到触发门限值时，氮气加速控件会激活为可用状态，可用状态是在用户界面上显示且可触发的状态。
步骤S310，当接收到作用于氮气加速控件的触发信号时，控制虚拟车辆进行加速。
在一些实施例中，氮气加速控件是触摸显示屏上显示的控件。当氮气加速控件处于可用状态时，若用户对氮气加速控件进行按压，则终端接收到作用于氮气加速控件上的触发信号，从而根据该触发信号控制虚拟车辆进行加 速。
终端可根据氮气属性值的剩余可用氮气进行加速，也即加速过程需要不断消耗氮气属性值中的氮气，当氮气属性值中的氮气消耗完毕时，控制虚拟车辆退出加速状态。
在一些实施例中，若虚拟车辆在加速过程中与其它物体发生碰撞，则终端也会控制虚拟车辆退出加速状态。
步骤S311，在控制虚拟车辆保持漂移状态的过程中，若车头方向与行驶方向之间的夹角小于第一阈值时，控制虚拟车辆恢复为正常行驶状态。
终端可将动态拖漂牵引力切换为正常行驶牵引力，该正常行驶牵引力用于控制虚拟车辆处于正常行驶状态。
步骤S312，在控制虚拟车辆保持漂移状态的过程中，若车头方向与行驶方向之间的夹角小于第一阈值时，将虚拟车辆的地面摩擦力，从第二摩擦力数值修改为第一摩擦力数值。
同时，应用程序还将虚拟车辆的地面摩擦力，从第二摩擦力数值修改为第一摩擦力数值。
在一些实施例中，第一摩擦力数值是根据虚拟车辆的速度实时确定的。在预设速度区间内，虚拟车辆的速度和地面摩擦力呈正相关关系。
在一些实施例中，第二摩擦力数值是预先设定的较小经验值。
步骤S313，在接收到目标交互控件对应的操作结束事件后，若车头方向与行驶方向之间的夹角小于第二阈值时，控制虚拟车辆在目标时长后从漂移状态切换为正常行驶状态。
在接收到目标交互控件对应的操作结束事件时，若车头方向与行驶方向之间的夹角较小(比如小于10°)，会进入另一种短暂的漂移状态。该“短暂的漂移状态”可称为点漂状态，点漂状态是与拖漂状态不同的一种状态。应用程序会控制虚拟车辆在短暂的目标时长后，从漂移状态切换为正常行驶状态。
在一些实施例中，应用程序根据虚拟车辆的速度和地面摩擦力，计算虚拟车辆从漂移状态衰减为正常行驶状态之间的衰减时长；当衰减时长大于最短漂移时长时，控制虚拟车辆按照衰减时长从漂移状态衰减为正常行驶状态；当衰减时长小于最短漂移时长时，控制虚拟车辆按照最短漂移时长从漂移状 态衰减为正常行驶状态。
在一些实施例中，在接收到目标交互控件对应的操作结束事件时，若车头方向与行驶方向之间的夹角小于第二阈值时，应用程序还将虚拟车辆的地面摩擦力，从第二摩擦力数值修改为第一摩擦力数值，以便虚拟车辆从点漂状态切换为正常行驶状态。
此外，由于点漂状态也是漂移状态，因此应用程序还执行步骤S308，在漂移状态(点漂状态)的持续期间，持续增加所述虚拟车辆的氮气属性值。点漂状态可以供用户快速积攒少量的氮气属性值，在通过拖漂方式或普通漂移方式累积的氮气属性值即将达到触发门限值时，用户可利用点漂状态积攒够剩余的氮气值。
综上所述，通过本实施例提供的方法，在接收到目标交互控件对应的操作结束事件后，若车头方向与行驶方向之间的夹角大于第一阈值，则控制虚拟车辆保持漂移状态；使得在控制保持虚拟车辆处于漂移状态的过程中，用户可以只控制车头方向与行驶方向之间的夹角即可，不需要同时按压方向键和漂移控件，只需要按压方向键来控制车头方向即可，降低了操作难度，提高了在某些不适合双手长时间操作场景下的人机交互便捷度。
本实施例提供的方法，还通过在接收到目标交互控件对应的操作结束事件后，在每次接收到用户的方向控制操作时，判断虚拟车辆的车头方向与行驶方向之间的夹角是否大于阈值，若虚拟车辆的车头方向与行驶方向之间的夹角大于第一阈值，则保持漂移状态，并根据虚拟车辆处于漂移状态(拖漂)的持续时间来累积氮气加速控件的氮气属性值。通过较为简洁的人机交互方式，使得用户能够快速积攒可用氮气值，从而更多地获得奖励性质的氮气加速控件。
本实施例提供的方法，还通过在接收到目标交互控件对应的操作结束事件后，若虚拟车辆的车头方向与行驶方向之间的夹角小于第二阈值，则进入点漂状态，并根据虚拟车辆处于漂移状态(点漂)的持续时间来累积氮气加速控件的氮气值。通过较为短暂的人机交互方式，使得用户能够快速积攒少量的可用氮气值，同时不会大幅度改变虚拟车辆的行驶方向，从而在拖漂状态或普通漂移状态下已经累积的氮气属性值即将达到门限值时，用户可利用点漂状态更快地获得奖励性质的氮气加速控件。
在一个示意性的例子中，S601，用户打开应用程序，开始赛车游戏；S602，用户通过按压按键(方向键和漂移键)的方式，控制车辆进入漂移；S603，用户松开按键，取消漂移触发操作；S604，应用程序控制赛车保持漂移状态，保持漂移状态也可称为拖漂。
S605，若用户选择回正车头，则用户可以触发如下操作：
1、点击方向键，把车头朝着漂移方向反向转动；
2、持续减小车头与车运动方向之间的夹角；
3、当这个夹角小于一定度数后，可以脱离漂移状态。
S606，应用程序控制赛车结束漂移，当漂移回正车头成功后，车辆进入正常行驶状态。
S607，若用户选择不回正车头，则用户可以触发如下操作：
1、当车处于拖漂的时候，车头会有一个自动回正力；
2、适当的点击方向键，把车头朝着漂移方向同向转动；
3、保持住车头与车运动方向之间的夹角基本不变；
4、保持无限拖漂状态。
在一些实施例中，在拖漂过程中，用户界面上还可以叠加显示第一字样“拖漂”71，如图7所示。另一方面，在拖漂过程中，虚拟车辆在赛道上因拖漂而产生的轮胎痕迹72也会明显偏长，如图8所示。
参考图5可知，本申请实施例中的赛车在延续漂移的过程中，不单单有一个惯性速度V，同时还有一个比较大的‘拖漂’动力F2存在，这个动力会和摩擦力f共同作用。同时，F/f的力量计算方式是动态变化的，最终的感觉类似于赛车在做匀速圆周运动(是实际情况肯定是动态的弧线)，理论上可以保持赛车的‘拖漂’状态无限持续下去。
示意性的，图9示出了一种示意性实施例下的动态漂移牵引力F2和摩擦力f的计算方式。动态漂移牵引力F2是随着赛车的实时速度变化，车速越快，动态漂移牵引力F2越大；车速达到一定程度后，动态漂移牵引力F2不再增大；摩擦力f也是随着赛车的实时速度变化，且摩擦力f的大小与赛车实时速度的平方成正比。
在拖漂过程中，用户需要实时操控虚拟赛车的车头方向，比如控制车头 方向与行驶方向之间的夹角在35°至45°左右。之所以用户需要操控车头方向，是因为用户需要实时的控制车头方向不能与行驶方向的夹角太小，太小会退出漂移状态。拖漂的操作核心就在于，用户要控制住车头方向与行驶方向的夹角，保持赛车受到的合力类似一个向心力，做类似圆周运动。实际上路线并不是标准的圆弧，是实时都在变化的不标准弧线。这就是赛道设计出的乐趣，不同的赛道弧度需要玩家控制不同的拖漂角度。
在一些实施例中，在拖漂需要结束的时候，玩家需要操控车头转动，让车头方向与行驶方向的夹角为0°，这样赛车就处于正常行驶状态了，动态漂移牵引力F2切换成了正常行驶牵引力F1。F1是一个定值，摩擦力f依然随着速度增大而增大，正常行驶牵引力f与摩擦力F1最终能达到平衡，赛车能在直线上做匀速直线运动，符合真实世界中的车辆的动力设计原理。
在一个可选的实施例中，在步骤603之后，若用户松开按键后，虚拟车辆的车头方向与行驶方向之间的夹角在10°以内，则不进入拖漂状态。而是进入另一种短暂的漂移状态，也称点漂状态。赛车会保持短暂的漂移状态后，从漂移状态切换为正常行驶状态。在一些实施例中，在点漂过程中，用户界面上还可以叠加显示第二字样“点漂”74，如图10所示。
