Abstract

A drive diagnosis device includes: a storage unit in which travel records of a moving body and past drive diagnosis results from past drive diagnoses executed for the moving body are stored; and a diagnosis processing unit that executes a drive diagnosis based upon driver'"'"'s skills for driving the moving body, and personal characteristics of the driver and/or experience of the driver by using the travel records and the past drive diagnosis results stored in the storage unit.

Claims

1. A drive diagnosis device, comprising:

a storage device configured to store travel records of a moving body and past drive diagnosis results from past drive diagnoses executed for the moving body, wherein the travel records of the moving body are transmitted, via a network, from a terminal device in the moving body and are obtained based on signals outputted from a plurality of sensors including a gyro sensor, an azimuth sensor, and an acceleration sensor; and

a hardware processor configured to execute a drive diagnosis based upon driver'"'"'s skills of a driver for driving the moving body, personal characteristics of the driver, and experience of the driver by using the travel records and the past drive diagnosis results stored in the storage device,

wherein the hardware processor determines the personal characteristics of the driver based on records of past drive diagnosis results including (i) a plurality of frequencies each indicating a number of times that a score value representing drive diagnosis results was awarded over a predetermined time period in the past, (ii) a plurality of succession values each indicating a number of times that a score value was successively awarded over the predetermined time period in the past, and (iii) a score variance indicating an extent of variance among score values representing the drive diagnosis results obtained over the predetermined time period in the past.

2. The drive diagnosis device according to claim 1, wherein:

the hardware processor determines the driver'"'"'s skills based upon the travel records.

3. The drive diagnosis device according to claim 1, wherein:

the hardware processor determines the personal characteristics of the driver based on;

(i) records each indicating a number of times the moving body was driven during a traveling time block, (ii) records indicating durations of time over which the moving body was continuously driven, (iii) records indicating intervals between drive diagnoses, and (iv) an age and a gender of the driver.

4. The drive diagnosis device according to claim 1, wherein:

the hardware processor determines the experience of the driver based upon (i) a length of time over which the drive diagnosis has been in the use, and (ii) a number of times the drive diagnosis has been used.

5. A drive diagnosis system, comprising:

a terminal device configured to obtain information pertaining to travel of a moving body based on signals outputted from a plurality of sensors including a gyro sensor, an azimuth sensor, and an acceleration sensor; and

a center device comprising a hardware processor and configured to communicate with the terminal device via a communication line,

wherein the hardware processor of the center device is configured to;

receive, via a network, travel records pertaining to the moving body based upon the information from the terminal device;

store, in a storage device, the travel records of the moving body and past drive diagnosis results from past drive diagnoses executed for the moving body;

execute a drive diagnosis based upon driver'"'"'s skills of a driver for driving the moving body, personal characteristics of the driver, and experience of the driver by using the travel records and the past drive diagnosis results stored in the storage device,

wherein the personal characteristics of the driver are determined based on records of past drive diagnosis results including (i) a plurality of frequencies each indicating a number of times that a score value representing drive diagnosis results was awarded over a predetermined time period in the past, (ii) a plurality of succession values each indicating a number of times that a score value was successively awarded over the predetermined time period in the past, and (iii) a score variance indicating an extent of variance among score values representing the drive diagnosis results obtained over the predetermined time period in the past; and

transmit results of the drive diagnosis to the terminal device; and

wherein the terminal device is configured to display the results of the drive diagnosis transmitted from the center device.

6. The drive diagnosis system according to claim 5,

wherein the terminal device comprises a diagnosis result screen displaying a score value determined based upon the personal characteristics and/or the experience of the driver of the moving body.

7. A terminal device comprising:

a communication interface configured to receive information pertaining to travel of a moving body obtained based on signals outputted from a plurality of sensors including a gyro sensor, an azimuth sensor, and an acceleration sensor;

a storage device configured to store travel records pertaining to the moving body based upon the information received by the communication interface and past drive diagnosis results from past drive diagnoses executed for the moving body; and

a hardware processor configured to execute a drive diagnosis based upon driver'"'"'s skills of a driver for driving the moving body, personal characteristics of the driver, and experience of the driver by using the travel records and the past drive diagnosis results stored in the storage device,

wherein the personal characteristics of the driver are determined based on records of past drive diagnosis results including (i) a plurality of frequencies each indicating a number of times that a score value representing drive diagnosis results was awarded over a predetermined time period in the past, (ii) a plurality of succession values each indicating a number of times that a score value was successively awarded over the predetermined time period in the past, and (iii) a score variance indicating an extent of variance among score values representing the drive diagnosis results obtained over the predetermined time period in the past,

wherein the communication interface is further configured to provide results of the drive diagnosis.
