“…Recovering the braking energy and reusing it can significantly improve the fuel economy of a vehicle which is subject to frequent braking events such as a city bus. [6][7][8][9] The more regenerative braking operates, the greater the improvement in fuel economy which can be obtained theoretically. When the driving motor as the generator operates in all feasible fields without any constraint to the greatest extent possible, the vehicle can acquire the greatest amount of additional energy.…”

The extended-range electric vehicle (E-REV) is an electric vehicle concept that has a light engine to allow an extended driving range. One of the most important features of these vehicles, based on electricity, is their ability to recover significant amounts of braking energy in a process known as regenerative braking. The more driving motor operates widely as generator, the more braking energy can be absorbed. However, it is not realistic in terms of performance for components. This study proposes three regenerative braking torque maps as the constraints to consider their performance. The results of fuel economy for simulations while applying proposed torque maps are compared with those of simulations without any constraints to evaluate effect of regenerative braking for E-REV bus according to characteristic of driving cycle. The characteristics of driving cycles are analyzed to find relationship between driving cycle and fuel economy. The aggressiveness of the driving cycles shows a linear relationship with regard to the difference in the fuel economy. This result can be used to develop power distribution control strategies with regenerative braking models to improve fuel economy levels.

“…When the regenerative braking power is bigger than the driver's intended braking power, the brake system generates only the regenerative braking torque. When this occurs, the BCU should control the magnitude of regenerative braking torque from the regenerative electric power of motor/generator in order to maintain a brake feeling similar to that of a conventional vehicle (Gao et al, 1999). In this paper, the control algorithm for maximizing regenerative braking torque is performed in order to increase the quantity of battery charge.…”

“…Therefore, friction braking should be needed together with the regenerative braking and a control algorithm is required to ensure active co-operative control between the regenerative braking and friction braking [3] [4]. This study proposes a co-operative control system of the regenerative braking for an automatic transmission (AT)-based HEV using the electronic wedge brake (EWB) on the front wheel, and the hydraulic brake on the rear wheel.…”

This research proposes a regenerative braking co-operative control system for the automatic transmission (AT)-based hybrid electric vehicle (HEV). The brake system of the subject HEV consists of the regenerative braking and the electronic wedge brake (EWB) friction braking for the front wheel, and the hydraulic friction braking for the rear wheel. A regenerative braking co-operative control algorithm is suggested for the regenerative braking and friction braking, which distributes the braking torque according to the driver's demand. A vehicle test was performed to evaluate the proposed braking system and cooperative control algorithm.
