1. A driving assistance system for assisting a driver to drive a vehicle, comprising:
- a behavior detecting unit in the vehicle and configured to detect a current behavior of the driver;
a processor;
a memory storing a program which causes the processor to perform a process, the process comprising;
storing a behavior history, which is a past behavior history of the driver, in a history storage unit;
determining an unsafe state by comparing a transition of the current behavior detected by the behavior detecting unit with the behavior history of the driver corresponding to a current driving path, in a state determining unit; and
storing attention-necessary place information representing an attention-necessary place where the driver should carefully drive the vehicle, in a place information storage unit; and
a notifying unit disposed in the vehicle and configured to give a notification to the driver when the processor determines the unsafe state,wherein, on the basis of the attention-necessary place information, the processor determines a distance between a current place and the attention-necessary place, andwherein the processor causes the notifying unit to increase a notification level of the notification as the vehicle get close to the attention-necessary place.

Abstract
A driving assistance system includes a history storage unit, a behavior detecting unit, a state determining unit, and a notifying unit. The history storage unit stores a behavior history which is a past behavior history of a driver. The behavior detecting unit detects a current behavior of the driver. The state determining unit determines an unsafe state by comparing the transition of the behavior detected by the behavior detecting unit with the behavior history of the driver corresponding to a current driving path. If the state determining unit determines the unsafe state, the notifying unit gives notification to the driver.

5. A driving assistance method executed in a driving assistance system for assisting a driver to drive a vehicle, the drive assistance system comprising:
-
a behavior detecting unit disposed in the vehicle; a notifying unit disposed in the vehicle; a processor; and a memory storing a program to be executed by the processor, the driving assistance method comprising; a history storing step of storing a behavior history, which is a past behavior history of the driver, in a history storage unit; a behavior detecting step of detecting a current behavior of the driver, by the behavior detecting unit; a behavior comparing step of comparing a transition of the current behavior detected by the behavior detecting step with the behavior history of the driver corresponding to a current driving path, using the processor; a state determining step of determining an unsafe state on the basis of a comparison result of the behavior comparing step, using the processor; a notifying step of giving a notification to the driver, by the notifying unit, when the unsafe state is determined by the state determining step; and a place information storing step of storing, in a place information storage unit, attention-necessary place information representing an attention-necessary place where the driver should carefully drive the vehicle, wherein, on the basis of the attention-necessary place information, the processor determines a distance between a current place and the attention-necessary place, and wherein the processor causes the notifying unit to increase a notification level of the notification as the vehicle get close to the attention-necessary place.
