Madrid demo EBSF_2

Driver Assistance
In Madrid, TEKIA and CRTM will focus on green driver assistance systems implementation. The main goals are to change the driving style of the drivers to a more efficient one and to estimate the variation in fuel consumption due to the change in driving style by using a driving style indicator that correlates with fuel consumption and results, intuitive for drivers.

The green driver assistance systems includes an on-board driving processor and driver HMI, a back office application for data processing and report, and a smartphone application for drivers. An algorithm will model a reference acceleration and braking profile for each of the bus movements (approach to stop, detention, exit from stop and traffic), by considering static and dynamic factors (type of vehicle, route characteristics, use of A/C, passenger load, service delays and others). It extracts global indicators which characterize driving style independently of external factors (factors affecting fuel consumption but not dependent on driving style, such as traffic conditions) and are correlated to fuel saving and comfort (also including on board temperature and sharp turn monitoring).

Madrid demonstrator will analyse driver style and fuel savings because of the application of the green driver assistance and comparing with a scenario before “no EBSF_2 situation”. It will also focus on minimizing the impact on travel times, optimizing (reducing the need for) previous driver training, and normalizing fuel consumption in order to accurately measure fuel savings. Normalization algorithms will take into account factors such as route slope, obtained dynamically, passenger load and traffic factors.
