Driver feedback

  1. Understand effect of driving behaviour on fuel consumption.
  2. Quantify potential of accelerator pedal force feedback to reduce fuel consumption by encouraging long-term retention of eco-driving training.
  1. 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.
  2. 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.

Implementation strategy

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.
