Evaluation system for vehicle operating conditions and evaluation method thereof

An evaluation system for operating conditions applied to a vehicle, comprising:

• a controller which functions to:
• determine whether or not an operation which worsens fuel economy has been performed;
• when it is determined that the operation which worsens fuel economy has been performed, respectively calculate an actual amount of consumed fuel and an amount of fuel which would have been consumed had the operation which worsens fuel economy not been performed;
• and
• calculate an amount of fuel consumed in excess due to the operation which worsens fuel economy by subtracting the amount of fuel which would have been consumed had the operation which worsens fuel economy not been performed from the actual amount of consumed fuel,
• the evaluation system further comprising a display device for displaying the calculated excess fuel consumption;
• wherein the controller further functions to determine that the operation which worsens fuel economy has been performed when the vehicle decelerates by a greater deceleration than a predetermined rapid deceleration determination value;
• and
• wherein the controller further functions to:
• rank the driving skill of a driver based on the frequency with which operations which worsen fuel economy are performed;
• and
• reduce the rapid deceleration determination value as the driving skill rank increases.

• the evaluation system further comprising a display device for displaying the calculated excess fuel consumption;
• wherein the controller further functions to:
• calculate a drive force of the vehicle based on the vehicle operating conditions;
• calculate an excess drive force by subtracting a running resistance from the calculated drive force;
• and
• calculate an excess drive force ratio by dividing the excess drive force by a drive force at full load, and
• the display device displays the calculated excess drive force ratio.
