Pollution derived from transportation systems is a worldwide, timelier issue than ever. The abatement actions of harmful substances in the air are on the agenda and they are necessary today to safeguard our welfare and that of the planet. Environmental pollution in large cities is approximately 20% due to the transportation system. In addition, private traffic contributes greatly to city pollution. Further, “vehicle operating life” is most often exceeded and vehicle emissions do not comply with European antipollution standards. It becomes mandatory to find a solution that respects the environment and, realize an appropriate transportation service to the customers. New technologies related to hybrid–electric engines are making great strides in reducing emissions, and the funds allocated by public authorities should be addressed. In addition, the use (implementation) of new technologies is also convenient from an economic point of view. In fact, by implementing the use of hybrid vehicles, fuel consumption can be reduced. The different hybrid configurations presented refer to such a series architecture, developed by the researchers and Research and Development groups. Regarding energy flows, different strategy logic or vehicle management units have been illustrated. Various configurations and vehicles were studied by simulating different driving cycles, both European approval and homologation and customer ones (typically municipal and university). The simulations have provided guidance on the optimal proposed configuration and information on the component to be used.

Braking torque distribution strategy is not only related to the tracking performance of the blended braking system in commanding the braking signal, but is also related to the energy utilization efficiency of the blended braking system. In this paper, a new braking torque distribution strategy is designed for a blended braking system consisting of a motor braking system and a friction braking system. In contrast to the classic braking torque distribution strategy, which adjusts the braking torque distribution ratio based on the braking strength, the newly designed braking torque distribution strategy adjusts the braking torque that is allocated to the motor braking system and friction braking system, according to the command braking torque signal, the braking actuators’ dynamic characteristics and the motor's electrical characteristics. In addition, a three‐layer controller is designed to ensure the execution of the proposed braking torque distribution strategy and the stability of the blended braking system. Compared to the classic distribution strategy, based on braking strength, numerical simulation results show that the braking energy recovery of the blended braking system has been improved by 16% in normal braking conditions and has been improved by 84% in emergency braking conditions under the new braking torque distribution strategy.
