Abstract：Aiming at the problem in high consumption of fuel oil，large starting torque and starting slowly in the truck，the energy saving

principle and working mode of electro- hydraulic hybrid system were investigated，and electro- hydraulic hybrid technology was put

forward to apply to the truck.Vehicle drving mode was changed according to logic threshold control strategy，and the simulation model was

established on AMESim according to the vehicle dynamics modle. The parameters of the system were established according to the actual

conditions.The simulation results show that the electro-hydraulic hybrid system has improved significantly in the driving performance and

fuel economy of the vehicle. Compared with the traditional vehicle，electro-hydraulic hybrid system has saved fuel consumption about

27.9%. The simulation results will be a certain reference value for the later research of electro-hydraulic hybrid car in energy saving.

Key words：heavy-duty truck；electro-hydraulic hybrid technology；AMESim；energy saving
