<h2>手自一体中的手动档</h2>
<p>我建议如果买自动档的话一定要买手自一体的，其实这个还不叫手动档，叫自动档中的手动模式。</p>
<p>什么时候用呢？</p>
<p>a. <strong>刹车失灵</strong>。在高速时直接拉手刹是会有翻车风险的，这时候最好的方法就是切换到手动档模式，一档一档往下降。这个方法其实纯手动档会更明显，只是会对变速箱有破坏作用，而自动档在降档时会自动提高转速来匹配当前的时速，会影响减速效果。</p>
<p>b. <strong>出地库时</strong>。地库的出口一般都有比较大的坡度，这时候为了保持高扭矩，就要持续的保持1或者2档，我一般是1档。用手动模式控制在1档，即可，回到平地时，切换到自动模式即可。</p>
<p>c. <strong>拥堵时</strong>。拥堵时跟车，很怕和前车距离太大导致有车TMD插进来，这时候怎么办？用手动模式，2档起步，跟车时油门大一点就行，因为1档有时候起步确实比较慢......</p>
<h2>如何起步更快</h2>
<p>要决：快速脱离1档和2档（按6档位进行讲解）。
操作：迅速把油门踩到2000转或以上，这时候智能点的变速箱是不会给你升档的，但是不升档的话，后面转速再高速度也不会太快，而且太高转速嘛，对发动机影响不好。所以在到2000转或以上地，松一下油门，这时候变速箱会自动给你到2档。2档到3档也一样，只是踩到2500再松，再同理3档4档，根据我的经验起步加速时，3档或4档踩到3000左右，加速效果会非常好。总结一下就是1和2档是过渡档，快速脱离，3和4是起步加速最佳档位，5档是高速超车最佳档位，6档是巡航档位。</p>
<p>这里有个小技巧不知该说不该说：停车时停在人行横道那根线那儿留点距离，然后等垂直方向的红灯亮起一秒之后，松刹车滑行，脚放油门，大概2秒左右我们方向的绿灯亮起，开始上面的操作。因为有了怠速的滑行，1档加速会顺很多，而且对发动机也好一点。
（为了安全起见，请慢速起步，这里只是技术研究）</p>
<h2>自动起停如何使用？</h2>
<p><strong>要决</strong>：短时间停车（<8s）不要启用
<strong>操作</strong>：istop还有其他类似的功能，现在大部分车都有了。怎么用呢？大部分车不会车一停就直接熄火，像小马哥，有个判断机制，轻踩刹车到停车，是不会熄火的，深踩刹车才会熄火。这样我会先轻踩到红绿灯处，如果到绿灯的时间超过5秒就会再深踩刹车，没超过的话就轻踩着，保持发动机启动状态。</p>
<h2>什么时候使用自动降档？</h2>
<p>自动降档是要油门<strong>快速</strong>踩<strong>到底</strong>才会触发的功能。所以我们要根据这两个触发条件来决定何用用该功能。</p>
<p>a. <strong>超车</strong>。上一篇文章也讲到了，中途超车，操作方式非常简单，快速把油门踩到底。</p>
<p>如果起步超车就不能用降档了，因为起步时是从1档加上去的，没必要降，用<strong>快速起步</strong>的操作方式就行，起步时如果你想很猛烈的超车，就在3档时猛踩油门，记住这时不能踩到底，而且踩得要线性，不要突然一下。如果对手没有那么强，等4档时再踩猛点油门也行。</p>
<p>b. <strong>上坡</strong>。这里不是指出地下车库哈，因为从车库出来，起步就1档，还降个毛线啊。这里指的是比如上一座桥，这座桥有一定的坡度。我之前还蛮多次碰到这种情况，在桥上有点坡度时，速度上不去，这时候一脚踩到底，车子速度一下就起来了。</p>
<p>最后讲到这里，回顾一下与发动机和变速箱相关的影响操控的几个点：</p>
<p>速度输出线性，动力强，油门极速反应（<strong>发动机</strong>）
智能变速，极速升降档，无感升降档，自动降档（<strong>变速箱+电控</strong>）</p>
<p>这几个点都与我们整车的这些表现相关，缺一不可：<strong>超车成功率，上坡速度，油门灵敏度，加速的线性程度。</strong></p>
<p>这也引申出一个非常重要的结论：<strong>买车前可以先多看看车评，然后一定要根据这些点自己去试驾，看能否满足自己操控感受，因为操控是在参数里面看不出来的。</strong></p>
<p><strong>*驾车安全最重要，优良的操控性能也能大大的提升安全性</strong></p>
