1. A vehicle driver feedback system comprising a control unit and a display unit, the control unit being arranged for registering a driver-influenced vehicle driving parameter, and the display unit being positioned in the vehicle and arranged for displaying information to the vehicle driver, the control unit further being arranged for:
iteratively calculating and storing at least one score value based on the at least one driver-influenced vehicle driving parameter, wherein the at least one score value (SE, SF, SW, SU) reflects a magnitude of driver-induced energy waste; driver-induced fuel wasted; driver-induced vehicle wear; unsafe driving; or a weighted combination of at least two thereof, and displaying on the display unit during driving of the vehicle a graphical score value development over time or relative to a travelled route as feedback to the vehicle driver,wherein the score value, when reflecting unsafe driving, reflects the sum of one or more of:
the level of lateral acceleration above a threshold value; the rate of change of vehicle longitudinal deceleration above a threshold value; the level of vehicle speed above the current vehicle speed limitation; the level of acceleration above a threshold value in residential areas, urban areas or in areas with low vehicle speed limitation; or the distance to the vehicle in front below a threshold value,or
wherein the score value development relative to the travelled, route is displayed for a route length in the range of 0.1-80 kilometres. |
