Abstract
A driving skill in input driving data is acquired from driving skill classification unit, driving data, which includes a driving skill higher than the driving skill in the input driving data and of which a similarity to the input driving data is at least a predetermined similarity, is selected from among driving data stored in a driving data storage unit, a difference between the selected driving data and the input driving data is detected, and a notice on the detected difference is issued as driving advice. As a result, it is possible to present suitable advice to improve a driving skill taking into account the skill and type of a driver.
Claims4
A driving assistance device comprising:
- driving data storage unit configured to store driving data on a plurality of drivers in association with driving skills of the drivers;
- driving skill classification unit created on the basis of driving data on drivers whose driving skills are known, the driving skill classification configured to receive driving data as input, and determine a driving skill in the driving data;
- driving data acquisition unit configured to receive input of driving data;
- similarity calculation unit configured to calculate a similarity between two pieces of driving data;
- difference detection unit configured to detect a difference in driving operation from the two pieces of driving data;
- driving assistance unit configured to give advice on driving, wherein
- the driving assistance unit further configured to:
- acquire, from the driving skill classification unit, a driving skill in the driving data input to the driving data acquisition unit;
- select driving data, which includes a driving skill higher than the driving skill in the input driving data and of which a similarity to the input driving data calculated by the similarity calculation unit is at least a predetermined similarity, from among the driving data stored in the driving data storage unit;
- detect a difference between the selected driving data and the input driving data by the difference detection unit;
- and
- issue a notice on the detected difference as driving advice.
