Abstract

An advice provision apparatus calculates the driving condition of the vehicle for every predetermined travel section, for the purpose of comparison with the driving condition in the previous travel section. The driving condition of the current section is evaluated in a relative manner based on the comparison of at least two travel sections, even when the absolute assessment of the driving condition is difficult. Thus, the advice provision apparatus can accurately and precisely diagnose the driving condition of the driver.

Claims

1. An advice provision apparatus comprising:

a vehicle information acquisition unit for acquiring vehicle information that represents a condition of a vehicle;

a diagnosis unit for diagnosing a driving condition of the vehicle for a travel section based on the vehicle information acquired by the vehicle information acquisition unit and for providing a diagnosis result for the travel section, the travel section being a unit of travel by the vehicle having a predetermined travel distance;

an advice generation unit for generating advice to be provided for a driver of the vehicle based on the diagnosis result provided by the diagnosis unit; and

an advice notification unit for notifying the driver of the advice generated by the advice generation unit, wherein

the diagnosis unit provides the diagnosis result for each travel section that satisfies the predetermined travel distance, and compares the diagnosis result of a subject travel section during a travel event with the diagnosis result of a previous travel section that was diagnosed before the subject travel section and occurred within the same travel event as the subject travel section, and

the advice generation unit generates the advice in regards to the diagnosis result of the subject vehicle when the diagnosis unit determines that the diagnosis result of the subject travel section is worse than the diagnosis result of the previous travel section,

wherein the travel event starts when an accessories (ACC) switch is turned on and ends when the ACC switch is turned off.

2. The advice provision apparatus of claim 1, wherein the diagnosis unit diagnoses multiple items of a driving condition and determines whether two of the multiple items have an individual diagnosis result of the subject travel section that is greater than a standard threshold when the diagnosis result of the subject travel is worse than the diagnosis result of the previous travel section, and

the advice generation unit does not generate the advice when the diagnosis result of the subject travel section is greater than the standard threshold.

3. The advice provision apparatus of claim 1, wherein

the diagnosis unit diagnoses multiple items of the driving condition, and

the advice generation unit generates the advice on each of the multiple items based on the diagnosis result of each of the multiple items with the reservation that the advice for a specific item is not generated for a predetermined period if the specific item has deteriorated diagnosis results for consecutive travel sections.

4. The advice provision apparatus of claim 3, wherein each of the multiple items has a weighting factor, and

the driving condition of the target travel section is diagnosed based totally on the diagnosis results of the multiple items respectively weighted by the weighting factor.

5. The advice provision apparatus of claim 4, wherein

the advice notification unit notifies the driver of the advice in an order based on weighting.

6. The advice provision apparatus of claim 1, wherein the advice notification unit notifies the driver of the advice when the vehicle is stopping.

7. The advice provision apparatus of claim 1, wherein the advice generation unit generates the advice when the vehicle is stopping.

8. A driving condition diagnosis apparatus comprising:

a vehicle information acquisition unit for acquiring vehicle information that represents a condition of a vehicle; and

a diagnosis unit for diagnosing a driving condition of the vehicle for a travel section based on the vehicle information acquired by the vehicle information acquisition unit, and for providing a diagnosis result for the travel section, the travel section being a unit of travel by the vehicle having a predetermined travel distance, wherein

the diagnosis unit provides the diagnosis result for each travel section that satisfies the predetermined travel distance, and compares the diagnosis result of a subject travel section during a travel event with the diagnosis result of a previous travel section that was diagnosed before the subject travel section and occurred within the same travel event as the subject travel section, to enable advice regarding the diagnosis result of the subject vehicle to be generated when the diagnosis unit determines that the diagnosis result of the subject travel section is worse than the diagnosis result of the previous travel section,

wherein the travel event starts when an accessories (ACC) switch is turned on and ends when the ACC switch is turned off.

9. A method for advice position, the method comprising:

acquiring vehicle information that represents a condition of a vehicle diagnosing a driving condition of the vehicle for a travel section based on the vehicle information acquired by an act of acquiring the vehicle information, and providing a diagnosis result for the travel section, the travel section being a unit of travel by the vehicle having a predetermined travel distance;

generating advice to be provided for a driver of the vehicle based on the diagnosis result; and

notifying the driver of the advice generated by an act of generating the advice, wherein

the act of diagnosing a driving condition further comprises providing a diagnosis result for each travel section that satisfies the predetermined travel distance, and comparing the diagnosis result of a subject travel section during a travel event with the diagnosis result of a previous travel section that was diagnosed before the subject travel section and occurred within the same travel event as the subject travel section, and

the act of generating advice further comprises generating the advice based on the diagnosis result of the subject vehicle when the diagnosis result of the subject travel section is worse than the diagnosis result of the previous travel section,

wherein the travel event starts when an accessories (ACC) switch is turned on and ends when the ACC switch is turned off.

10. A method for diagnosing a driving condition comprising:

acquiring vehicle information that represents a condition of a vehicle; and

diagnosing a driving condition of the vehicle for a travel section based on the vehicle information acquired by an act of acquiring the vehicle information, and providing a diagnosis result for the travel section, the travel section being a unit of travel by the vehicle having a predetermined travel distance, wherein

the act of diagnosing a driving condition further comprises providing a diagnosis result for each travel section that satisfies the predetermined travel distance, and comparing the diagnosis result of a subject travel section during a travel event with the diagnosis result of a previous travel section that was diagnosed before the subject travel section and occurred within the same travel event as the subject travel section, to enable advice regarding the diagnosis result of the subject vehicle to be generated when the diagnosis result of the subject travel section is worse than the diagnosis result of the previous travel section,

wherein the travel event starts when an accessories (ACC) switch is turned on and ends when the ACC switch is turned off.
