An automated method for predicting the best locations to begin coasting when approaching a breaking event, such as a roundabout or slip road, or negotiating undulating terrain.
This approach accounts for differences in vehicle payload, aerodynamics, rolling resistance and elevation changes.
Results showed a 5-13% increase in coasting distance compared to an experienced driver attempting to maximise coasting without assistance.
% fuel saving
Up to 10% reduction in fuel consumption (5% on average) depending on route, payload and choice of coasting strategy.
% CO2e Saving
Up to 15 kg reduction in CO2e per trip (7 kg on average)
Cost of implementation
Less than £5000 required to implement an in-cab driver assist tool which integrates with the SRF Logger.
The research team can advise on optimal coasting locations based on offline calculations. A real-time implementation may be ready for commercial use within 5 years.
