Abstract

Vehicle operation diagnosis devices, methods, and programs diagnose a driver'"'"'s operation of a vehicle based on a vehicle parameter and a driving diagnosis judgment standard that is set for a diagnosis item. The devices, methods, and programs acquire information that pertains to an accident factor for a high-accident location in the vicinity of the vehicle where not less than a specified number of accidents have occurred in the past, modify the driving diagnosis judgment standard based on the accident factor for the high-accident location, in a case where the vehicle is traveling in the high-accident location, and acquire the vehicle parameter. The devices, methods, and programs diagnose the driver'"'"'s operation of the vehicle based on the modified driving diagnosis judgment standard and the acquired vehicle parameter.

Claims

1. A vehicle operation diagnosis device that diagnoses a driver'"'"'s operation of a vehicle based on a vehicle parameter and a driving diagnosis judgment standard that is set for a diagnosis item, the vehicle operation diagnosis device comprising:

a factor acquisition unit that acquires information that pertains to an accident factor for a high-accident location in the vicinity of the vehicle where not less than a specified number of accidents have occurred in the past;

a diagnosis judgment standard modification unit that, in a case where the vehicle is traveling in the high-accident location, modifies the driving diagnosis judgment standard based on the accident factor for the high-accident location;

a parameter acquisition unit that acquires the vehicle parameter; and

a vehicle operation diagnosis unit that diagnoses the driver'"'"'s operation of the vehicle based on the driving diagnosis judgment standard that was modified by the diagnosis judgment standard modification unit and on the vehicle parameter that was acquired by the parameter acquisition unit.

2. The vehicle operation diagnosis device according to claim 1, wherein

the driving diagnosis judgment standard is defined by a threshold value for a parameter that pertains to the vehicle,

the vehicle operation diagnosis unit diagnoses the driver'"'"'s operation of the vehicle by comparing the vehicle parameter that was acquired by the parameter acquisition unit with the parameter threshold value that defines the driving diagnosis judgment standard, and

the diagnosis judgment standard modification unit changes a threshold value of a parameter that pertains to the accident factor for the high-accident location.

3. The vehicle operation diagnosis device according to claim 2, wherein

the diagnosis judgment standard modification unit changes the threshold value of the parameter that pertains to the accident factor for the high-accident location to a value that is more readily attainable than the value in a case where the vehicle is not traveling in a high-accident location.

4. The vehicle operation diagnosis device according to claim 1, further comprising:

a diagnosis result guidance unit that provides guidance with respect to a result of the diagnosis of the driver'"'"'s operation of the vehicle by the vehicle operation diagnosis unit.

5. A vehicle operation diagnosis method that diagnoses a driver'"'"'s operation of a vehicle based on a vehicle parameter and a driving diagnosis judgment standard that is set for a diagnosis item, the vehicle operation diagnosis method comprising the steps of:

acquiring information that pertains to an accident factor for a high-accident location in the vicinity of the vehicle where not less than a specified number of accidents have occurred in the past;

modifying the driving diagnosis judgment standard based on the accident factor for the high-accident location, in a case where the vehicle is traveling in the high-accident location;

acquiring the vehicle parameter; and

diagnosing the driver'"'"'s operation of the vehicle based on the modified driving diagnosis judgment standard and the acquired vehicle parameter.

6. A computer program that is installed in a computer and that diagnoses a driver'"'"'s operation of a vehicle based on a vehicle parameter and a driving diagnosis judgment standard that is set for a diagnosis item, the computer program causing the computer to perform the functions of:

acquiring information that pertains to an accident factor for a high-accident location in the vicinity of the vehicle where not less than a specified number of accidents have occurred in the past;

modifying the driving diagnosis judgment standard based on the accident factor for the high-accident location, in a case where the vehicle is traveling in the high-accident location;

acquiring the vehicle parameter; and

diagnosing the driver'"'"'s operation of the vehicle based on the modified driving diagnosis judgment standard and the acquired vehicle parameter.
