【摘要】：為得到駕駛?cè)嗽诳v坡路段上行車時(shí)的駕駛負(fù)荷及其影響因素,在山區(qū)復(fù)雜線形公路上開展了自然駕駛試驗(yàn),采集了真實(shí)駕駛習(xí)慣條件下的汽車行駛速度、軌跡、加速度等運(yùn)行參數(shù)和駕駛?cè)诵碾娦盘?hào),分析了公路縱面線形參數(shù)、汽車加(減)速度與駕駛?cè)诵穆试鲩L(zhǎng)率H_(RI)之間的關(guān)系.結(jié)果表明,縱坡參數(shù)、加速度與H_(RI)三者之間相互影響.坡長(zhǎng)與H_(RI)之間存在較弱的正相關(guān)性;坡度與H_(RI)之間存在較強(qiáng)的相關(guān)性,其中下坡路段的相關(guān)性強(qiáng)于上坡路段,并且坡長(zhǎng)越長(zhǎng),坡度增加導(dǎo)致H_(RI)的增長(zhǎng)越明顯;H_(RI)與加(減)速度正相關(guān),坡度越大,H_(RI)對(duì)加(減)速度的變化越敏感,且下坡路段減速度與H_(RI)的相關(guān)性較上坡路段加速度與H_(RI)的相關(guān)性更顯著.
[Abstract]:To get the driving load and its influence factors when driving the driver in the longitudinal section, in the mountains on the road to carry out complex linear driving test, collecting real driving habits under the condition of the vehicle speed, trajectory, acceleration and other operating parameters and driving exciting signal, the paper analyzes the highway vertical alignment parameters of vehicle (minus) speed and the driver's heart rate H_ (RI). The relationship between the results show that the longitudinal slope parameters, acceleration and H_ (RI) the mutual influence between the three. The length of slope and H_ (RI) and there was weak positive correlation between slope degree and H_; (RI) there is a strong correlation between. The correlation is stronger than the downhill and uphill road, slope length, slope of the increase of H_ (RI) growth is more obvious; H_ (RI) and plus (minus) rate of positive correlation, the greater the slope, H_ (RI) on the plus (minus) the more sensitive the speed change, and downhill reduction with the speed of H_ (RI The correlation between the acceleration of the upper slope and the H_ (RI) is more significant than that of the upper slope.
