1前言
斯堪尼亚(Scania)于2012年推出一款全新主动预测地形的高级巡航控制系统,通过GPS确定车辆位置和预测前方道路地形,控制上坡和下坡路段车速,进入坡道时,巡航系统识别坡度并计算合适的加速度,使驱动扭矩达到最大,避免在爬坡时多次切换挡位,下坡时免费利用整车势能获得较大的车速,整车行驶过程可节省燃油 3%[1] O
利用ADAS智能地图识别前方道路的坡度、弯道曲率、限速信息计算车辆所需的最优扭矩和挡位,预见性巡航(PredictiveCruiseControl,PCC)系统比一般驾驶员节油 3%~4% ,对于特定有利路况,节油可达 6% ,成为商用车节能减排的重要手段[2-3]。(剩余2973字)
