FUEL-SAVING DRIVING DIAGNOSTIC DEVICE, FUEL-SAVING DRIVING DIAGNOSTIC SYSTEM, TRAVEL CONTROL DEVICE, FUEL-SAVING DRIVING RATING DEVICE, AND FUEL-SAVING DRIVING DIAGNOSTIC METHOD
First Claim
1. A fuel-saving driving diagnostic device, comprising:
- an accelerator operation quantity condition calculating unit that calculates an upper limit value of an accelerator operation quantity during fuel-saving driving of a vehicle based on vehicle type information of the vehicle;
an accelerator operation quantity condition determining unit that determines whether the accelerator operation quantity of the vehicle is larger than the upper limit value of the accelerator operation quantity calculated by the accelerator operation quantity condition calculating unit;
a travel situation determining unit that determines whether a travel situation of the vehicle is a predetermined travel situation; and
a fuel-saving driving diagnosing unit that diagnoses fuel-saving driving by determining whether to make a determination by the accelerator operation quantity condition determining unit in accordance with a determination result by the travel situation determining unit.

Abstract
An accelerator opening determining unit determines whether an accelerator opening achieved through an accelerator operation by a driver of a vehicle exceeds an upper limit value thereof. A travel distance adding-up unit adds up a travel distance within accelerator-opening upper limit value when the accelerator opening is not determined to exceed the upper limit value. When the accelerator opening is determined to exceed the upper limit value, the travel distance adding-up unit adds up a travel distance exceeding accelerator-opening upper limit value. A fuel-saving driving rating unit rates the driving of the driver based on each added-up value added up by the travel distance adding-up unit.

12. A fuel-saving driving diagnostic method executed by a fuel-saving driving diagnostic system that diagnoses fuel-saving driving of a vehicle, comprising:
-
calculating an upper limit value of an accelerator operation quantity during fuel-saving driving of a vehicle based on vehicle type information of the vehicle; firstly determining whether the accelerator operation quantity of the vehicle is larger than the upper limit value of the accelerator operation quantity calculated in the calculating; secondly determining whether a travel situation of the vehicle is a predetermined travel situation; diagnosing fuel-saving driving by determining whether to make a determination in the firstly determining in accordance with a determination result in the secondly determining; and rating step of rating the fuel-saving driving based on a determination target travel distance, which is a travel distance of the vehicle selected as a target for the determination in the firstly determining, and a travel distance of the determination target travel distance for which the accelerator operation quantity is not determined to be larger than the upper limit value of the accelerator operation quantity in the firstly determining.
