Abstract

A driving diagnosis device includes storage device which stores plural pieces of advice and a processor. The processor makes a diagnosis on driving by a driver according to vehicle information indicating at least one of behavior of a certain vehicle and an operation of the driver while the driver is driving the certain vehicle. The processor judges a degree of influence, on the diagnosis, of a driving experience of the driver before the driver drives the certain vehicle according to history information as for a history of the driver driving one or more different vehicles including the certain vehicle. And the processor determines to present to the driver a piece of advice stored in the storage device, from among plural pieces of advice, in association with a combination of a result of the diagnosis and the judged degree of influence.

determines to present to the driver a piece of advice stored in the storage device, from among plural pieces of advice, in association with a combination of a result of the diagnosis and the judged degree of influence.

2. The driving diagnosis device according to claim 1, wherein the processor extracts or calculates from the history information a value indicating a temporal factor which affects a degree of adaptability of the driver to the certain vehicle, and judges the degree of influence using the value.

3. The driving diagnosis device according to claim 2, wherein:

the history information includes at least starting time information indicating time at which the driver has started driving the certain vehicle;

the processor judges the degree of influence so that magnitude of the degree of influence may monotonically decrease with respect to a length of time lapse from the time indicated by the starting time information.

4. The driving diagnosis device according to claim 2, wherein:

the history information includes at least driving time information indicating a length of time in which the driver drives another vehicle other than the certain vehicle; and

the processor judges the degree of influence so that magnitude of the degree of influence may monotonically increase with respect to the length of the time indicated by the driving time information.

5. The driving diagnosis device according to claim 2, wherein:

the history information includes at least ending time information indicating time at which the driver has completed driving another vehicle other than the certain vehicle;

the processor judges the degree of influence so that magnitude of the degree of influence may monotonically decrease with respect to a length of time lapse from the time indicated by the ending time information.

6. The driving diagnosis device according to claim 1, wherein:

the history information includes at least first vehicle specification information indicating a specification of the certain vehicle, and second vehicle specification information indicating a specification of another vehicle other than the certain vehicle in the one or more vehicles; and

the processor judges the degree of influence so that the magnitude of the degree of influence may monotonically increase with respect to magnitude of a difference between the specification indicated by the first vehicle specification information and the specification indicated by the second vehicle specification information.

7. The driving diagnosis device according to claim 6, wherein the processor judges the degree of influence using a coefficient which regulates whether the degree of influence is positive or negative when the difference between the specification indicated by the first vehicle specification information and the specification indicated by the second vehicle specification information is positive.

8. The driving diagnosis device according to claim 1, wherein:

the history information includes at least number-of-vehicle information indicating a number of the one or more vehicles;

the processor judges the degree of influence as zero when the number of vehicles indicated by the number-of-vehicle information is 1;

the processor judges the degree of influence so that the magnitude of the degree of influence monotonically decreases with respect to the number of vehicles indicated by the number-of-vehicle information when the number of vehicles indicated by the number-of-vehicle information is larger than 1.

9. The driving diagnosis device according to claim 1, wherein:

in the storage device, each piece of the plural pieces of advice is stored in association with a combination of the result of the diagnosis, the degree of influence, and a result of a prior diagnosis;

the history information includes the result of the prior diagnosis obtained when the driver drove another vehicle other than the certain vehicle; and

the processor determines to present to the driver apiece of advice stored in the storage device in association with a combination of the obtained result of the diagnosis, the judged degree of influence, and the result of the prior diagnosis included in the history information.

10. The driving diagnosis device according to claim 1, further comprising:

a reader which reads the history information from a non-transitory computer-readable storage medium which stores the history information; and

a writer which writes the history information as for driving the certain vehicle to the non-transitory computer-readable storage medium.

11. The driving diagnosis device according to claim 1, further comprising:

a receiver which receives the history information over a network from an information storage device; and

a transmitter which transmits to the information storage device the history information as for the driving of the certain vehicle over the network.

12. The driving diagnosis device according to claim 1, further comprising an output device which outputs the advice which the processor determined to present.

13. The driving diagnosis device according to claim 12, wherein the processor controls timing of outputting by the output device the advice which the processor determined to present according to the vehicle information.

14. A driving diagnosis system, comprising:

an onboard device equipped into a certain vehicle; and

a management device which communicates information with the onboard device over a network, wherein;

the onboard device includes;

a first processor which acquires, from the certain vehicle, vehicle information indicating at least one of behavior of the certain vehicle and an operation of the driver while a driver is driving the certain vehicle; and

a first transmitter/receiver which communicates with the management device over the network;

the management device comprises;

a second processor;

a second transmitter/receiver which communicates with the onboard device over the network; and

a history storage device which stores first history information as for a history of the driver driving a vehicle other than the certain vehicle;

the onboard device or the management device comprises an advice storage device which stores plural pieces of advice;

the first processor or the second processor makes a judgment on driving of the driver according to the vehicle information;

the first processor or the second processor judges a degree of influence, on the diagnosis, of a driving experience of the driver before the driver driving the certain vehicle according to at least one of the first history information and second history information as for a history of the driver driving the certain vehicle; and

the first processor or the second processor determines to present advice stored in the advice storage device in association with a combination of a result of the obtained diagnosis and the judged degree of influence to the driver.

15. The driving diagnosis system according to claim 14, wherein:

the onboard device generates or acquires the second history information, and transmits the second history information from the first transmitter/receiver to the management device over the network; and
