Evaluation system for vehicle operating conditions and evaluation method thereof
First Claim
1. 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 accelerates by a greater acceleration than a predetermined rapid acceleration 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 acceleration determination value as the driving skill rank increases.

Abstract
A calculation unit (3) determines whether or not an operation which worsens fuel economy has been performed, and if it is determined that an operation which worsens fuel economy has been performed, the calculation unit (3) respectively calculates the actual amount of consumed fuel and an amount of fuel that would have been consumed had the operation that worsens fuel economy not been performed. The calculation unit (3) then calculates an amount of fuel consumed in excess due to the operation which worsens fuel economy by subtracting the amount of fuel that would have been consumed had the operation that worsens fuel economy not been performed from the actual amount of consumed fuel. A display (4) displays the calculated excess fuel consumption amount.
