The calculation of optimal driving speed profiles for metro vehicles that improve energy saving and, thus, reduce costs, are investigated. The optimization problem is solved in two different steps: in the first one, a Dynamic Programming Optimization (DPO) algorithm (including slopes and curves effects) is used to find a set of pseudo-optimal speed cycles; the objective is to minimize the electrical...
The TU/e has developed a battery electric vehicle (BEV) using a VW Lupo 3L as donor platform. The differences between the initial design calculations and actual vehicle performance are analysed. Battery charging and discharging efficiency, acceleration performance and top speed are as expected. The range at low, constant speeds is less than expected, due to a higher rolling resistance and lower power...
Due to increased public discussion on global climate change and increased awareness of environmental issues in general, a variety of transport related strategies are being developed to reduce the energy consumption of road travel. Pre-trip journey planners and on-trip navigation systems are widely used to identify optimal routes. Travel time, trip distance and travel cost are usually used as criteria...
