Abstract
In this paper, an adaptive rule based controller for an anti-lock regenerative braking system (ARBS) of a series hybrid electric bus (SHEB) has been proposed. The proposed controller integrates the regenerative braking and wheel anti-lock functions by controlling the electric motor of the hybrid vehicle, without using any conventional mechanical anti-lock braking system. The performance of the proposed system is evaluated by a comprehensive vehicle dynamics model in MATLAB/Simulink. Using the designed ARBS, the braking and regenerative performances of SHEB have significantly improved in slippery roads while the slip ratios are kept between 0.15 and 0.20.

Abstract
In this paper, the development and optimization of Power Distribution Control Strategy (PDCS) have been
performed for a Hybrid Energy Storage Systems (HESS) of a Series Hybrid Electric Bus (SHEB). A
common PDCS is based on the use of Ultra-Capacitor (UC) pack. A new simple PDCS is developed as a
battery based one. For the battery based PDCS, four parameters are introduced for tuning the PDCS
performance. The Design of Experiment (DoE) method is utilized to optimize the parameters of the battery
based PDCS for the driving cycles and the vehicle controllers. The results show the optimized battery based
PDCS performance for some cases are better than the UC based PDCS performance. Vice versa, for some
cases the performance of the UC based PDCS is better than the battery based PDCS. Finally, the costs
rising from the HESS (about 66%) is reasonable when considering the over double increase in the battery
life-time when using an appropriate PDCS.
