Abstract
The dynamics and fuel efficiency of hybrid electric tracked vehicle are largely restricted with energy management strategy. A new energy management strategy for engine power following and battery pack power compensating is proposed according to the output characteristics of power source and the driving demand of vehicle, and a power balance method is presented for engine, battery pack and motor, etc. A real-time simulation platform for the energy management of hybrid electric tracked vehicle with "driver and vehicle controller" is established in dSPACE. The real-time simulation research on the operation input of driver is conducted. The simulation results show that the engine works according to the optimal fuel consumption curve and the in-time power compensation of battery packs, and the energy management strategy meets the power changes of some vehicle driving, such as maximum speed and B/2 steering situation, to implement the better dynamics and fuel efficiency of hybrid electric tracked vehicle.
