Abstract: To invesigate the feasibility of control strategy in hybrid electric transmission tracked vehicle, the hardware-in-the-loop simulation is introduced. A new control strategy based on voltage control for hybrid electric transmission tracked vehicle is proposed, according to vehicles structure style and DC-DC convertion control. Real drivers input and controller are applied, and the controlled object and its plant are simulated based on the model of hybrid electric transmission tracked vehicles drive system by real-time computation in dSPACE. The hardware-in-the-loop simulation platform for studying on the control strategy is established, including CAN in the loop. The control strategy is validated by experiment through the hardware-in-the-loop simulation platform. The results show that the control strategy is feasible and effective, and drivers demand is satisfied.
