Information processor, information processing method, and recording medium

An information processing method executed by a computer, comprising:

• acquiring section position information for identifying a position of a first section on a traveling lane for the traveling of a driver's vehicle and a position of a second section on an oncoming lane at an intersection located in front of the driver's vehicle;
• sequentially acquiring vehicle behavior information regarding behavior of the driver's vehicle when traveling through the intersection and storing, as history information, a history of driving characteristic parameters representing the driving characteristics of the driver included in the sequentially acquired vehicle behavior information;
• sequentially calculating the driver's vehicle position information for identifying the driver's vehicle position where the driver's vehicle exists when traveling through the intersection based on the vehicle behavior information;
• determining which of the first section and the second section the driver's vehicle position identified by the driver's vehicle position information is located, based on the section position information;
• and
• extracting a specific driving characteristic parameter corresponding to at least one of the first section and the second section from the history information based on the result of the determination in the determining.

A recording medium having embodied thereon a program comprising computer-implemented modules including:

• a module that acquires section position information for identifying a position of a first section on a traveling lane for the traveling of a driver's vehicle and a position of a second section on an oncoming lane at an intersection located in front of the driver's vehicle;
• a module that sequentially acquires vehicle behavior information regarding behavior of the driver's vehicle when traveling through the intersection and stores, as history information, a history of driving characteristic parameters representing the driving characteristics of the driver included in the sequentially acquired vehicle behavior information;
• a module that sequentially calculates the driver's vehicle position information for identifying the driver's vehicle position where the driver's vehicle exists when traveling through the intersection based on the vehicle behavior information;
• a determination module that determines which of the first section and the second section the driver's vehicle position identified by the driver's vehicle position information is located, based on the section position information;
• and
• a module that extracts a specific driving characteristic parameter corresponding to at least one of the first section and the second section from the history information based on the result of the determination by the determination module.
