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.
Claims24
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.

- 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.
