The invention discloses a new energy hybrid power switching system based on line change. The new energy hybrid power switching system comprises a vehicle bearing weight measuring unit used for measuring or collecting the value of the mass borne by vehicle wheels; the road slope angle detection unit is used for collecting a change value of a road surface inclination angle; the vehicle driving linear speed measuring unit is used for collecting the vehicle driving linear speed; the vehicle driving torque calculation unit is used for calculating the vehicle driving torque on the slope and keeping the vehicle driving torque unchanged; the electric driving and fuel driving judging unit is used for judging whether the vehicle driving torque required for keeping the vehicle running linear speed unchanged exceeds the preset maximum driving torque of electric driving or not when the inclination angle of the road surface changes or the vehicle bearing weight changes; and the hybrid power switching controller is used for controlling automatic switching between electric driving and fuel driving. A large amount of repeated operation data does not need to be adopted as a reference working condition, the driving mode of the hybrid power vehicle is adjusted in real time according to the driving road condition, and the vehicle is operated with the optimal efficiency.

    本发明公开一种基于线路变化新能源混合动力切换系统,包括:车辆承载重量测量单元用于测量或者采集车辆车轮承载的质量大小数值;道路坡度角检测单元用于采集采集路面倾角的变化数值;车辆行驶直线速度测量单元用于采集车辆行驶直线速度;车辆驱动转矩计算单元用于计算斜坡上车辆驱动转矩保持不变;电动驱动与燃油驱动判断单元,判断路面倾角变化或车辆承载重量变化时,车辆行驶直线速度保持不变所需车辆驱动转矩是否超出电动驱动预设的最大驱动转矩;混合动力切换控制器,控制电动驱动和燃油驱动的自动切换。本发明无需采用大量重复运作数据作为参考工况,实时根据行驶路况调节混合动力车辆的行驶模式,以达到最优的效率运行车辆。
