Abstract

A driving advice provision apparatus generates an advice, based on diagnosis performed on multiple diagnosis items regarding the driving condition of the vehicle and based on the diagnosis results from those diagnosis items, and provides the generated advice to the driver. The multiple diagnosis items are classified into different categories according to the diagnosis methods. For the diagnosis items suitable to the comparative evaluation rather than the quantitative evaluation, a diagnosis result A for the previous evaluation section is compared with a diagnosis result B for the current evaluation section for yielding a comparative evaluation and for advice generation, thereby enabling an effective advice generation and provision in terms of diagnosis item category.

Claims

1. A driving advice provision apparatus comprising:

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

a diagnosis unit for diagnosing on diagnosis items regarding a driving condition of the vehicle based on the vehicle information acquired by the information acquisition unit;

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

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

the diagnosis items are multiple items of diagnosis,

the diagnosis unit uses a diagnosis method that is suitable for respective items of diagnosis,

the advice generation unit notifies the advice at a timing that is suitable for respective items of diagnosis,

the notification unit notifies the generated advice at a time of stopping the vehicle or during a stopping of the vehicle,

the notification unit includes an advice selection unit that at least selects an advice having a high priority assigned to each of the advices in advance, and

the notification unit notifies the driver of the vehicle of the advice selected by the advice selection unit in a prioritized manner.

2. The driving advice provision apparatus of claim 1, wherein

the advice generation unit generates the advice at a time of stopping the vehicle or during a stopping of the vehicle.

3. The driving advice provision apparatus of claim 2, wherein

the multiple items of diagnosis includes environment-related diagnosis items and safety-related diagnosis items,

the advice selection unit selects a high priority environment-related advice having the highest priority from among the generated advices on the environment-related diagnosis items, and selects a high priority safety-related advice having the highest priority from among the generated advices on the safety-related diagnosis items, and

the notification unit notifies the driver of the high priority environment-related advice and the high priority safety-related advice.

4. The driving advice provision apparatus of claim 3, wherein

the advice selection unit selects the high priority environment-related advice first, and then selects the high priority safety-related advice.

5. The driving advice provision apparatus of claim 3, wherein

the environment-related diagnosis items include (a) diagnosis items that are diagnosed by a travel section comparison diagnosis method that compares a target travel section with other travel section and (b) diagnosis items that are diagnosed by a stop time event diagnosis method that diagnoses a generation condition of an event that is possibly generated during the stopping of the vehicle, and

the safety-related diagnosis items include (a) diagnosis items that are diagnosed by a single section diagnosis method that diagnoses a driving condition of the target travel section based on a travel of the target travel section and (b) diagnosis items that are diagnosed by a travel time event diagnosis method that diagnoses a generation condition of an event that is possibly generated during a travel of the vehicle.

6. The driving advice provision apparatus of claim 5, wherein

among the environment-related diagnosis items, the advice concerning the diagnosis items diagnosed by the stop time event diagnosis method has higher priority than the advice concerning the travel section comparison diagnosis method, and

among the safety-related diagnosis items, the advice concerning the diagnosis items diagnosed by the travel time event diagnosis method has higher priority than the advice concerning the single section diagnosis method.

7. The driving advice provision apparatus of claim 6, wherein

each of the four diagnosis methods includes multiple diagnosis items, and

the generated advice concerning each of the multiple diagnosis items has a preset priority.

9. The driving advice provision apparatus of claim 1, wherein

the advice generation unit generates the advice at a time of stopping the vehicle or during a stopping of the vehicle.

10. The driving advice provision apparatus of claim 2, wherein

the multiple items of diagnosis includes environment-related diagnosis items and safety-related diagnosis items,

the environment-related diagnosis items and the safety-related diagnosis items are classified into respectively different diagnosis methods,

the advice selection unit selects a high priority environment-related advice having the highest priority from among the generated advices on the environment-related diagnosis items, and selects a high priority safety-related advice having the highest priority from among the generated advices on the safety-related diagnosis items, and

the notification unit notifies the driver of the high priority environment-related advice and the high priority safety-related advice.

11. The driving advice provision apparatus of claim 3, wherein

the advice selection unit selects the high priority environment-related advice first, and then selects the high priority safety-related advice.

12. The driving advice provision apparatus of claim 3, wherein

the environment-related diagnosis items include (a) diagnosis items that are diagnosed by a travel section comparison diagnosis method that compares a target travel section with other travel section and (b) diagnosis items that are diagnosed by a stop time event diagnosis method that diagnoses a generation condition of an event that is possibly generated during the stopping of the vehicle, and

the safety-related diagnosis items include (a) diagnosis items that are diagnosed by a single section diagnosis method that diagnoses a driving condition of the target travel section based on a travel of the target travel section and (b) diagnosis items that are diagnosed by a travel time event diagnosis method that diagnoses a generation condition of an event that is possibly generated during a travel of the vehicle.

13. The driving advice provision apparatus of claim 5, wherein

among the environment-related diagnosis items, the advice concerning the diagnosis items diagnosed by the stop time event diagnosis method has higher priority than the advice concerning the travel section comparison diagnosis method, and

among the safety-related diagnosis items, the advice concerning the diagnosis items diagnosed by the travel time event diagnosis method has higher priority than the advice concerning the single section diagnosis method.

14. The driving advice provision apparatus of claim 6, wherein

each of the four diagnosis methods includes multiple diagnosis items, and

the generated advice concerning each of the multiple diagnosis items has a preset priority.

8. A driving advice provision apparatus comprising:
