在驾校:学习手动挡 上路后:适应自动挡

  大多数人在驾校学习的车是手动挡,而在买车时很多人考虑到使用的方便与省力往往会选择自动挡。

  驾驶自动变速器的车一般只需要将挡位挂在“D”上,就可以放心上路了。汽车的自动变速器能够根据转速与油门的情况自动地从1挡升到4挡。然而,目前几乎所有的自动挡的车都设有“限制挡”,即“1”、“2”、“3”、“4”等一些挡位,其功能是限制自动变速箱的换挡时机,以实现发动机转速持续提升的目的,有利于发动机功率和扭矩的输出。如果挂到“3”,最高可以自动升到3挡;挂到“2”,可以最高升至2挡;如果挂到“1”就意味着变速器只能在1挡工作。

  利用“限制挡”的特殊功能,可以给人以驾驶手动挡车的类似感觉,车的动力性更易于表现。如在需要加速、超车或者上坡时,将“D”挡转换为“3”挡,可以令自动挡车普遍存在的“油门滞后”感得以明显改善。下坡时,由于车子自身的重力带动,车子会越跑越快。如果挂在D挡,而且轻踩油门,变速箱会自动升至高挡,这样车速就会越来越快。如果你不想有这样的结果,那么可以考虑挂在“3”挡或者“2”挡。
