Reducing the fuel consumption of vehicles leads often to an optimization task of the complete drive train. A significant influence to the fuel consumption is caused by the energy consumption of electric loads. An oversized generator, to supply the loads, leads to additional weight of the vehicle and additional costs, which should be avoided. To obtain the right size of the generator an analytical...
Optimization of systems is a challenging task. During this process adjustments of the model and the optimization algorithm will influence its success. Therefore, this paper introduces an analytical approach to verify the results achieved by an optimization process. This is done by pushing the observed mild hybrid electric vehicle (HEV) into the recuperation mode and the generator mode of the electrical...
The reduction of CO2 emissions and fuel consumption is a continuous challenge towards the optimization of hybrid and electric vehicles. The approach in this paper is to use the claw pole alternator as boost-recuperation-machine (BRM), to realize a mild hybrid electrical vehicle. The investigated parameters are the control strategy and the pulley ratio of the BRM. These parameters are easily adjustable...
