Attention calling system for vehicle
First Claim
1. An attention calling system for a vehicle, which calls attention of a driver when an attention level of the driver to driving the vehicle is lowered, comprising:
- attention level estimation means for estimating the attention level of the driver;
abnormal behavior detection means for detecting a predetermined abnormal behavior of the vehicle; and
alarm means including tactile information-presenting means for presenting tactile information via a tactile sense to the driver and a first alarm means for presenting information via at least one of an auditory sense and a visual sense to the driver,wherein said alarm means performs a presentation of the information by said first alarm means, as a first alarm, when the estimated attention level of the driver has become lower than a predetermined level, and performs a presentation of the tactile information by said tactile information-presenting means, as a second alarm, on condition that the attention level of the driver is lower than the predetermined level, the abnormal behavior of the vehicle is detected, and the first alarm has been performed at least once within a predetermined driving time period of the vehicle,wherein said attention level estimation means estimates the attention level of the driver, using steering amount parameters indicative of a steering amount by the driver acquired during a first predetermined acquiring time period, andwherein said abnormal behavior detection means detects the predetermined abnormal behavior of the vehicle, using the steering amount parameters acquired during a second predetermined acquiring time period shorter than the first predetermined acquiring time period.

Abstract
An attention calling system for a vehicle, which is capable of performing an alarm by presenting tactile information while causing a driver to have a feeling of being convinced and a feeling of trust, thereby making it possible to effectively and appropriately call attention of the driver. In the attention calling system according to the present invention, the attention level of the driver is estimated, and an abnormal behavior (unstableness) of the vehicle is detected. Then, on condition that the estimated attention level of the driver is lower than a predetermined level and the abnormal behavior of the vehicle is detected, the tactile information is presented to the driver as an alarm for calling attention of the driver.
