The invention relates to a downshift operation system using road curvature, comprising: a gear switching machine comprising a gear handle, a transmission shift fork shaft, a reverse gear shaft, a clutch shift fork, a clutch, a first transmission shaft, a second transmission shaft, a transmission intermediate shaft and a plurality of gear combination sleeves; the pushing mechanical arm is arranged at the joint of the gear handle and the transmission shifting fork shaft and used for driving the gear handle to execute downshift processing on the gear switching machine when receiving the downshift control command; and the information conversion mechanism is used for sending out a downshift control command when a position where the imaging depth of field is smaller than or equal to a set depth of field threshold and the corresponding curvature is larger than or equal to a set curvature threshold exists in the current fitting curve. The downshift operation system utilizing the road curvature is safe, reliable and wide in application. Due to the fact that automatic downshift decision and downshift operation can be carried out based on the maximum curvature of the front road surface and the distance of the position where the maximum curvature appears, the situation that automobile turning is difficult to deal with is avoided.

    本发明涉及一种利用路面曲率的降档操作系统,包括:档位切换机械,包括档把、变速器拨叉轴、倒挡轴、离合器拨叉、离合器、变速器一轴、变速器二轴、变速器中间轴以及多个档位结合套;推送机械手臂,设置在挡把与变速器拨叉轴的连接处,用于在接收到降档控制命令时,驱动挡把执行对档位切换机械的降档处理;信息转换机构,用于在当前拟合曲线中存在成像景深小于等于设定景深阈值且对应曲率大于等于设定曲率阈值的位置时,发出降档控制命令。本发明的利用路面曲率的降档操作系统安全可靠、应用广泛。由于能够基于前方路面的最大曲率以及出现最大曲率的位置远近进行自动化降档决策和降档操作,从而避免汽车转弯难以应对的场景发生。
