1前言
斯堪尼亞(Scania)于2012年推出一款全新主動預(yù)測地形的高級巡航控制系統(tǒng),通過GPS確定車輛位置和預(yù)測前方道路地形,控制上坡和下坡路段車速,進(jìn)入坡道時,巡航系統(tǒng)識別坡度并計(jì)算合適的加速度,使驅(qū)動扭矩達(dá)到最大,避免在爬坡時多次切換擋位,下坡時免費(fèi)利用整車勢能獲得較大的車速,整車行駛過程可節(jié)省燃油 3%[1] O
利用ADAS智能地圖識別前方道路的坡度、彎道曲率、限速信息計(jì)算車輛所需的最優(yōu)扭矩和擋位,預(yù)見性巡航(PredictiveCruiseControl,PCC)系統(tǒng)比一般駕駛員節(jié)油 3%~4% ,對于特定有利路況,節(jié)油可達(dá) 6% ,成為商用車節(jié)能減排的重要手段[2-3]。(剩余2973字)
