Description

根据限速调整定速巡航的方法的方法和定速巡航 技术领域
本发明属于汽车领域，提供了一种根据限速调整定速巡航的方法的方法和定速巡航。
背景技术
'你不是开得太快，是'飞'得太低。'这一小品台词诙谐夸张，但却发人深省。 11 月 8 日，现实版的'飞车'表演就在西宁市惊心上演。当日 17 时 10 分许，驾驶人雷某某驾驶青 B · 05170 号东风货车沿昆仑大道西段由东向西行驶至刘家寨村东口时，由于超速加之雷某某不注意观察前方事物，造成与由北向南横过道路的行人严某某相撞，致使严某某受伤，经送医院抢救无效于当日死亡。
超速行驶对行车安全为什么构成这么大的威胁？超速行驶主要有以下危害：一是超速行驶，视力下降，判断不准。驾驶人在行车中的视力称为动视力。一般来说，动视力比静视力低 10% 至 20% 。动视力与速度成反比，车速越快，视力下降越多。当时速为 60 公里时，视认距离为 240 米，而 80 公里时，视认距离减少到 160 米；车速越快，视野越窄，这就是所谓的'隧道型视野'。当时速为 40 公里时，视野为 100 度，时速为 100 公里时，视野仅为 40 度，这时两边的景物无法看清；二是超速行驶，反应距离延长。当时速为 60 公里时，人的反应距离为 16.7 米，当时速达 100 公里时，反应距离为 27.8 米。车速越快，反应距离越长，危险越大；三是超速行驶，制动距离延长。不同的路面，摩擦系数不同，车速越快，制动距离越长，发生事故的可能性陡增；四是超速行驶，干扰正常车流。超速行驶的车辆必然时刻处于超越正常行驶车辆的状态，每次超车无论是变道还是驶回原车道，都会形成交织点，而每个交织点就是一个交通事故隐患；五是超速行驶，加重事故后果。车速越快，动能越大，冲击力越大，发生事故碰撞时后果越严重。数据显示，当汽车时速 20 公里，把人撞死的几率为 10% ， 40 公里时超过 30% ， 60 公里时超过 90% ， 80 公里以上时则达到 100% 。由此可见，超速行驶是危险可怕的，'超速行驶'历来是公安交管部门整治的重点交通违法行为。
在高速路上行驶时，由于路面直且较宽，很多驾驶者会选择定速巡航功能，这样虽然可以省去一些操作上的麻烦，但是定速巡航往往会让人掉以轻心，高速路上路面情况虽然不太复杂，但是因为速度快偶尔的变化也会造成很严重的危害，所以在高速路上限速的路段也很多，而定速巡航往往让人在限速路段忘记减速，给自身和他人行车安全带来和很大的危害。
综上，需要针对使用定速巡航时经常忽略限速而给行车带来危害的情况，提供一种过预设车辆行驶道路匹配的限速，当车辆行驶在道路上时，根据道路限速设置定速巡航功能，使定速巡航更加智能化，同时增加行车安全性，避免超速。
