Analysis of a Driver Behaviour Improvement Tool to Reduce Fuel Consumption

A number of technologies have been introduced into new automobiles with the aim of reducing CO2 emissions. One method of improving fuel consumption is to improve driver behaviour, since eco-driving techniques can help save 10-15% of fuel. A retro-fittable driver behaviour improvement device has been developed and tested in real world conditions. The device provides real-time audio and visual feedback to the driver to improve his/her driving style. It was tested on 15 vans belonging to various companies in the UK and over 39,000km of data was collected. It was observed that use of the device saved an average 7.6% of fuel. Further analysis showed that the savings were obtained as a result of improvement in driving behaviour through reduction in harsh accelerations and early gear shifting into higher gears. There was also a reduction in the pedal busyness of drivers with the system fitted. A model was created using the data obtained to predict the fuel savings that can be achieved if the device is fitted onto a new vehicle.
