Item Driving cycle and road grade on-board predictions for the optimal energy management in EV-PHEVs(Institute of Electrical and Electronics Engineers Inc., 2014-10-01) Valera, J. J.; Heriz, B.; Lux, G.; Caus, J.; Bader, B.; Tecnalia Research & InnovationThe prediction of the driving cycle (vehicle speed profile versus time) and the road grade cycle (road grade profile versus time) can improve a variety of vehicle functions, especially the energy management of HEVs and PHEVs. The variability of the driving conditions (environment) together with the nonlinear and variable driver behaviour (driving style) makes the driving cycle 'on-board & real-time' prediction a highly complex task. This paper proposes an intelligent technique for the real time prediction of the vehicle speed and road grade profiles for the (selected) time horizon whilst the vehicle is in route. The proposed method uses an Artificial Neural Network which processes both the vehicle speed measurement (current and previous data samples) and some information related to the driving conditions present in the route, which could be obtained in advance from the new generation of vehicle navigation systems. The driving cycle and road grade on-board predictions allow the energy management system of HEV/PHEVs to achieve further reductions of fuel consumptions.Item NCV2015: A networked range extended electric vehicle for clean and efficient mobility(2012) Valera, J. J.; Heriz, B.; Arejita, B.; Isasi, L.; Tecnalia Research & Innovation; CCAMA Networked Range Extended Electric Vehicle (NCV2015) has been developed as a mobile platform for researching in technologies, powertrain system components and control algorithms for the future generation of low environmental impact electrified vehicles. An overview of the NCV2015 vehicle, including its control & I2V (Infrastructure to Vehicle) communication systems are presented in this paper. Thanks to the Information & Communication Technologies (ICTs) and the Intelligent Transport Systems (ITSs), the intelligent and optimized energy management strategies (i-EMSs) can be designed and tested thus improving the vehicle performance in terms of range, fuel consumption, and emissions. The i-EMS installed on the NCV2015, including its benefits and future improvements, is finally presented and discussed in this paper.
