    在实际行车中,正确运用行车制动器是保证轿车行驶平顺、乘客舒适的重要条件。要使乘客安全、平顺、舒适,必须做到少用制动踏板,正确运用制动。

    方法是:处理情况要有(you)预见性(xing),要提前抬起加速踏板,利用发动(dong)(dong)(dong)(dong)机(ji)怠速牵(qian)阻作用减速和(he)采取预见性(xing)剐动(dong)(dong)(dong)(dong),尽金避(bi)免(mian)(mian)紧(jin)急(ji)制(zhi)(zhi)动(dong)(dong)(dong)(dong)。假如行(xing)(xing)驶(shi)中(zhong)遇到突然(ran)(ran)情况。可采用“先急(ji)后松法”进行(xing)(xing)制(zhi)(zhi)动(dong)(dong)(dong)(dong),即******脚(jiao)制(zhi)(zhi)动(dong)(dong)(dong)(dong)先急(ji)速踩下,紧(jin)接着(zhe)级补第二脚(jiao),然(ran)(ran)后根据发生情况的距离慢慢松开(kai)制(zhi)(zhi)动(dong)(dong)(dong)(dong)踏板,并根据车(che)(che)速换入适当档位(wei),加速恢(hui)复正常行(xing)(xing)驶(shi),这(zhei)(zhei)种制(zhi)(zhi)动(dong)(dong)(dong)(dong)方法的特点(dian)是:当轿(jiao)车(che)(che)随着(zhe)制(zhi)(zhi)动(dong)(dong)(dong)(dong)的惯性(xing)点(dian)头(tou)时,乘客前俯成弓(gong)形,这(zhei)(zhei)时若马上松开(kai)制(zhi)(zhi)动(dong)(dong)(dong)(dong)踏板,乘客随着(zhe)轿(jiao)车(che)(che)回位(wei)的惯性(xing)必然(ran)(ran)往(wang)后仰(yang),这(zhei)(zhei)种运(yun)动(dong)(dong)(dong)(dong)很容易使人恶(e)心呕吐(tu)。为避(bi)免(mian)(mian)这(zhei)(zhei)种情况的发生,必须在(zai)轿(jiao)车(che)(che)点(dian)头(tou)刚开(kai)始(shi)间位(wei)时再补上******脚(jiao),使其不(bu)能迅(xun)速回位(wei),而后再慢慢松开(kai)制(zhi)(zhi)动(dong)(dong)(dong)(dong)踏板,使轿(jiao)车(che)(che)和(he)乘客渐(jian)渐(jian)复原以降低由于车(che)(che)速的变化所造(zao)成的来回冲击(ji),使乘客感(gan)到稳(wen)定。

    遇到(dao)突然悄(qiao)况需(xu)要紧急制(zhi)动时,为防(fang)(fang)止(zhi)车(che)轮抱死。应采用(yong)间歇(xie)踩(cai)(cai)制(zhi)动踏板的方法,即(ji)紧急制(zhi)动时不可一脚将(jiang)制(zhi)动踏板踩(cai)(cai)到(dao)底不动,而是踩(cai)(cai)到(dao)底后(hou)马上放(fang)松一点再踩(cai)(cai)下,越(yue)踩(cai)(cai)越(yue)重,越(yue)放(fang)越(yue)小。如(ru)此就可以防(fang)(fang)止(zhi)车(che)轮抱死而取(qu)得与ABS系(xi)统同样(yang)的制(zhi)动效果。这种方法需(xu)要在平坦(tan)的场(chang)地下、进行反复地练习(xi)才(cai)能掌握。
