- Understand effect of driving behaviour on fuel consumption.
- Quantify potential of accelerator pedal force feedback to reduce fuel consumption by encouraging long-term retention of eco-driving training.
- Analysis of the behaviour of two drivers identified differences in driving styles, and explained 7% fuel consumption differences between the two drivers when negotiating roundabouts.
- Driving simulator experiments showed that pedal force feedback led to a reduction in throttle pedal displacement of approx. 20%, with a corresponding reduction of fuel use.
% fuel saving
Pedal force feedback provides continuous in-cab cues to encourage retention of an eco-driving strategy, which otherwise tends to diminish with time.
% CO2e Saving
CO2 reduction not quantified directly but estimated to be proportional to fuel saving.
Cost of implementation
Per-vehicle cost could be less than £5000.
Pedal force feedback would have to be implemented by the vehicle manufacturer, but the technology has appeared on some cars. Field trials are needed to assess in-service performance and driver acceptability.
