Fuzzy, driving/regeneration, hybrid, sliding mode, 14-DoF model
In a front differential vehicle, four-wheels-drive ability called 4WD can be designed by using the electric traction system on rear wheels. Using in-wheel-electrical machine coupled to each of the rear wheels, driving/regeneration and stability enhancement can be obtained synchronously by summation and difference of enforced torques, respectively. For research section of mentioned pattern, proper modelling and simulation of driving realities are important for trust-worthy simulation results. So, a dynamical model with 14 degrees of freedom (14-DoF), using Dugoff’s tire model is considered in this paper. Also, power-train subsystems include of engine, clutch, gear box, and differential with electrical machine and battery models are used from ADVISOR vehicle simulation software. Considering an electrical machine on each rear wheel, sliding mode and fuzzy controllers have been designed to direct yaw moment control and driving mode control, respectively. Furthermore, braking pedal has been used for activation of regenerative braking operation in driving mode control. Forward simulation of vehicle, intelligent vehicle control based on road/driving condition and synchronous control of driving/regeneration and stability enhancement is the advantages of this paper. Simulations performed in MATLAB/SIMULINK environment demonstrate that the proposed structure can effectively enhance the vehicle performance in different modes.
