First Claim
Patent Images
1. A driving mental condition detecting apparatus comprising:
- physiological data detector for detecting physiological data of a driver of a vehicle;
navigator for obtaining travel data of said vehicle;
driving mental condition judger for judging a mental condition of a driver by multiplying each of said physiological data and said travel data by predetermined judgment coefficients, adding the products of the multiplications and comparing the sum of the products to a predetermined judgement threshold value; and
alarm generator for generating an alarm when the sum of the products is greater than the predetermined judgement threshold value, thereby indicating that said driver has a deteriorated driving mental condition.

Abstract
A driving mental condition detecting apparatus for detecting a deterioration state of driving mental conditions such as sleepiness, fatigue, and impatience occurring in a driver on the basis of physiological data detected from the driver and road travel data of a vehicle derived from a navigation system, thereby generating an alarm.

20. A driving mental condition detecting apparatus comprising:
-
physiological data detecting means for detecting physiological data of a driver of a vehicle; navigation means for obtaining travel data of said vehicle; driving mental condition judging means for judging whether said driver feels sleepy based on said physiological data and said travel data; and alarm generating means for generating an alarm when it is judged that said driver feels sleepy, wherein said driving mental condition judging means judges sleepiness of said driver in accordance with said physiological data and said travel data during a predetermined driving period of time. - View Dependent Claims (21, 22, 23, 24)
