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.
