The invention relates to the technical field of vehicle speed control, and discloses a vehicle speed energy-saving control method and device based on vehicle road fusion perception, and the method comprises the following steps: S1, judging whether a current vehicle activates vehicle speed energy-saving control or a reminding scene flag, if yes, entering a vehicle speed energy-saving control mode and implementing S2, and if not, entering a manual driving mode; s2, calculating the guiding speed of the current vehicle based on the combination of the vehicle-road fusion perception information and the road gradient, camber and speed limit information in the scene; s3, judging whether a barrier vehicle or a barrier vehicle driving into the same lane exists in a road section in front of the current vehicle or not, and obtaining a judgment result; and S4, calculating the optimal energy-saving vehicle speed of the current vehicle according to a judgment result. Through the V2V or V2I technology, fusion of vehicle-mounted sensing information and roadside sensing information is achieved, so that the vehicle obtains more accurate and reliable front traffic information, the vehicle obtains the front traffic state in time, the optimal energy-saving vehicle speed of the vehicle is calculated through a control strategy, and the purpose of saving energy during vehicle driving is achieved.
本发明涉及车速控制技术领域,公开了一种基于车路融合感知的车速节能控制方法及装置,包括以下步骤:S1:判断当前车辆是否激活车速节能控制或提醒场景flag,若是,进入车速节能控制模式并实施S2,若否,则为人工驾驶模式;S2:基于车路融合感知信息与场景内的道路坡度、弯度及限速信息的结合,计算出当前车辆的引导车速;S3:判断当前车辆前方路段是否存在障碍车辆或正驶入同车道的障碍车辆,获取判断结果;S4:根据判断结果计算出当前车辆的最优节能车速。通过V2V或V2I技术实现车载感知和路侧感知信息的融合,使车辆获得更为精确、可靠的前方交通信息,实现车辆及时获取前方交通状态并通过控制策略计算出车辆最优节能车速以达到车辆行驶节能的目的。
