坡道定點停車與起步的2大注意事項

坡道起步技巧是新駕駛員必須具備的基本技能,坡道起步是否有技巧呢?坡道起步要注意哪些問題呢?坡道起步一般問題會出在哪里呢?下面駕校聯盟小編給大家講解下坡道起步的兩大注意事項。

從坡道起步技巧的操作失敗現象來看,主要有兩種情況:一是起步熄火;二是起步后溜。

探尋坡道起步失敗的原因無外乎三個方面:一是油門跟不上;二是松手制動的時機不當;三是油門和離合器配合不好。

分析了坡道起步的原因,下面就是坡道起步技巧中的2大注意事項:

1、有手制動的坡道起步技巧

保持正確的駕駛姿勢,注意前方道路的各種交通情況,不得低頭下看。其操作順序是左腳踩離合器踏板,加速桿掛入低速檔,右腳徐徐踏加速踏板,左腳慢放離合器踏板,當反映至發動機聲音有變化或車身稍有抖動時,迅速松開手制動,并再稍踏下加速踏板,慢抬離合器踏板。注意,此時不能立即放松離合器踏板,而是要先跟油門后松離合器。因為上坡時汽車阻力大,起步所需動力也要大一些。關鍵點是松手制動的時機。若松得過早,會使車輛后溜:若松得過遲會造成熄火。最佳時機是當離合器踏板抬至半聯動位置,發動機聲音有變化時,立即松開。坡道起步要領可歸納為:音變、車抖、稍一停,緊跟油門松制動,油門大小看坡度,不溜不沖不熄火。

2、無手制動的坡道起步技巧

因無手制動或手制動有故障時,應采取無手制動起步方法。操作程序是左腳踩下離合器踏板,右手將變速桿掛入低速檔;右腳腳跟踏下制動板,左腳前掌踏在加速踏板上。起步時,右腳前掌踏下加速踏板,左腳前掌稍踏下加速踏板,左腳慢抬離合器。起步后,應完全松開離合器踏板。關鍵點是右腳前掌與腳跟隨的配合。這種坡道起步方法難度較大,不易掌握,一般配情況下不提倡使用,只作為一種應急方法。
