摘　　要：为提高商用车巡航系统的经济性与安全性,设计了考虑节油安全驾驶的商用车预见性自适应巡航控制系统(predictive adaptive cruise control system,PACC),基于前方道路坡度规划了预见性巡航经济车速,针对巡航过程中受前车影响产生制动干扰的问题,提出了一种利用前车信息进行优化的预见性自适应巡航控制策略。基于前方道路坡度设计了自适应车间距,规划主车行驶车速,实现了预见性自适应巡航行驶。基于一汽解放JH6重型商用车进行了实车试验,研究结果表明:该算法可以有效降低燃油消耗量并缓解驾驶员驾驶疲劳,为商用车辅助驾驶系统的开发提供了极为重要的理论及实际价值。In order to improve the economy and safety of commercial vehicle cruise system,a predictive adaptive cruise control system(PACC)is designed considering fuel saving and safe driving,and the economic speed of the predictive cruise is planned based on the road slope ahead. An optimized predictive adaptive cruise control strategy based on the front vehicle information is proposed to solve the problem of braking disturbance caused by the vehicle in front during cruise. Based on the gradient of the road ahead,the adaptive inter-vehicle distance is designed and the driving speed of the main vehicle is planned to realize the predictive adaptive cruising. A real vehicle test is carried out based on FAW JH6 heavy-duty commercial vehicle. The research results show that the algorithm can effectively reduce fuel consumption and driving fatigue,which provides extremely important theoretical and practical value for the development of commercial vehicle driving assistance system.
